Inherited-IRA Custodian Selection in 2026: Fidelity vs Schwab vs Vanguard vs Merrill vs Empower Head-to-Head

The default choice — keep the inherited account at the deceased owner's custodian — is the correct choice roughly 60% of the time and the wrong choice roughly 40% of the time. The correct-default cases are those where the deceased's custodian is one of the five majors (Fidelity, Charles Schwab, Vanguard, Merrill Edge, Empower) and the beneficiary's holding preferences align reasonably well with that custodian's product platform. The wrong-default cases are those where the deceased's account was at a small regional bank, a wire-house full-service brokerage charging AUM fees on inherited accounts, or an institutional-side plan record-keeper that treats the inherited-IRA rollover as a one-time transaction rather than a ten-year client relationship.^[1]

The reason this decision is quietly high-stakes is the compounding effect of the ten-year distribution window. Under the SECURE Act of 2019 and the final regulations issued by the Treasury under TD 10001 in July 2024, a non-EDB designated beneficiary who inherits an IRA in 2026 must fully distribute the account by December 31, 2036 — with annual RMDs required in years 1-9 if the deceased owner had reached their Required Beginning Date before death.^[2] A 0.35% annual fee delta between two custodians, compounded over ten years on a $500,000 inherited account with a moderate-growth portfolio, is roughly $19,000 in preserved value at the tenth-year distribution. A high-touch inherited-IRA service that catches a mistitling within the correctable window (covered in our custodian titling failure modes guide) is worth many multiples of that.

This article is the operating manual for choosing among the five largest US retail inherited-IRA custodians in 2026: the six decision variables that actually matter, a detailed head-to-head profile of each custodian, the trustee-to-trustee transfer mechanics for moving an account, a fee comparison table, three worked case studies, six most-common mistakes, and the 8-item pre-transfer checklist every primary beneficiary should execute before opening a successor inherited-IRA account. Before drilling into a specific custodian, the CalcLeap retirement calculator, the Traditional IRA calculator, the Roth IRA calculator, the 401(k) withdrawal calculator, and the income tax calculator handle the year-by-year distribution math that any custodian will need to administer.

The six decision variables

Every custodian selection decision reduces to six variables that can be measured against a common scale. The relative weight the beneficiary places on each depends on the account balance, the beneficiary's own investment sophistication, and the successor designation complexity, but all six matter for every inherited IRA above roughly $50,000.

Variable 1: Titling correctness at account opening

The single highest-stakes moment in the entire inherited-IRA lifecycle is the custodian's first account statement — the one mailed 30 to 45 days after the account owner's death. A title line that does not include the deceased owner's name and the words "as beneficiary" or "as beneficiary of" is a red flag that the account may have been inadvertently retitled as the beneficiary's own IRA under IRC §408(d)(3)(C) — which for a non-spouse beneficiary is a deemed distribution of the entire account balance under IRC §408(d)(1).^[3] Custodians vary widely in the quality of their titling protocols. Fidelity, Schwab, and Vanguard have automated inherited-IRA account setup workflows with the correct titling built in at the source-code level. Merrill and Empower are more likely to produce a mistitled account when the beneficiary's own IRA already exists at the same institution, because their branch-employee workflows can accidentally route the inherited account through an own-IRA opening path.

Variable 2: Successor beneficiary designation form quality

Once the inherited account is properly titled, the second-highest-stakes moment is filing the successor beneficiary designation — the form that names who inherits the account if the primary beneficiary dies during the 10-year window. Every major custodian requires a separate inherited-IRA-specific designation form, distinct from the standard IRA beneficiary form the primary may already have filed on their own IRAs. The forms vary significantly in the range of designation constructions they permit, the medium through which they can be filed (online vs paper), and whether trust-as-beneficiary and charity-as-beneficiary designations are supported.^[4]

Variable 3: Post-death service escalation

Every custodian offers a general customer-service line. Only some offer a dedicated inherited-IRA specialty desk staffed by employees trained on IRC §408(d)(3)(C), the four-category eligible designated beneficiary framework under IRC §401(a)(9)(E)(ii), and the Treas. Reg. §1.401(a)(9)-5 divisor mechanics — the technical knowledge required to competently handle a titling correction, a successor designation dispute, or an in-kind transfer request. When a mistitling or a service issue arises, the difference between reaching a competent specialist within 15 minutes and being routed through three general-service tiers over three business days can be the difference between a fixable clerical error and a Form 1099-R triggering a $150,000-plus tax event.

Variable 4: In-kind transfer capability

The inherited account will hold whatever securities the deceased owner held at death. The custodian's ability to receive and administer those securities without forcing liquidation determines whether the beneficiary can preserve the pre-death cost basis and asset allocation, or whether the account has to be reconstructed from cash. Fidelity, Schwab, and Vanguard can receive substantially any US-listed security and most non-partner mutual funds in kind through the standard ACAT (Automated Customer Account Transfer) system. Merrill Edge can receive US-listed securities but has occasional friction with certain non-partner mutual funds. Empower's institutional side often requires liquidation to cash before the account is opened at the new plan or the retail brokerage side, which can force realization of the deceased's pre-death gains in the account.^[5]

Variable 5: Fee schedule

All five major retail custodians waive maintenance fees on retail-brand inherited IRAs as of 2026. Fidelity, Schwab, and Vanguard also waive commissions on US-listed stocks and ETFs. The fee variance across custodians is dominated by transaction fees on non-partner mutual funds ($0-$50 per transaction), transfer-out fees ($0-$100 for a full ACAT-out), and, in Empower's institutional-side case, plan-level administration fees ranging from $30 to $150 per year depending on the terms negotiated by the former plan sponsor. Fee variance is a small factor on retail balances at Fidelity/Schwab/Vanguard/Merrill and a potentially significant factor at Empower's institutional side.^[6]

Variable 6: RMD administration for the 10-year window

Under Treas. Reg. §1.401(a)(9)-5 as amended by TD 10001 (July 19, 2024), a non-EDB designated beneficiary inheriting from an owner who died on or after their Required Beginning Date must take annual RMDs in years 1-9 of the 10-year window in addition to fully distributing the account by year 10.^[2] This year-by-year RMD requirement, resumed after the 2021-2024 transition-relief waiver stack under Notices 2022-53, 2023-54, and 2024-35 expired, is the primary annual administrative burden a custodian must handle for the beneficiary. Fidelity and Schwab have automated year-by-year RMD calculation with proactive notification, automated distribution setup, and portal-based visibility into the divisor stream. Vanguard and Merrill also support automated RMDs but with less proactive year-ahead notification. Empower's institutional-side administration varies by plan.

Fidelity Investments

Fidelity Investments is the largest US retirement account custodian by IRA asset count as of 2026, with approximately 15 million IRA households and roughly $2.9 trillion in IRA and retirement plan assets under administration.^[7] The inherited-IRA product is administered by Fidelity Brokerage Services LLC as an account subtype (product code INH-IRA) within the standard retail brokerage platform, and inherits the platform's full commission-free trading of US-listed stocks and ETFs, its no-transaction-fee mutual fund network (~3,300 funds), and its automated RMD service.

Titling convention. Fidelity's titling for an inherited IRA is "[Deceased Owner Full Legal Name], Deceased [MM/DD/YYYY], IRA FBO [Beneficiary Full Legal Name], as beneficiary" — matching the IRS model form exactly. The titling is applied at account setup by an automated workflow triggered by the death certificate and the deceased owner's beneficiary designation record; there is no branch-employee intervention step at which the titling can be inadvertently altered. Fidelity's account statements print the full title on the top-of-statement account identifier and on every downstream tax form (Form 1099-R distribution, Form 5498 fair market value).

Successor beneficiary form. Fidelity's inherited-IRA beneficiary designation form is Form FBS-INH-BEN-DES (2024 revision), submittable online through Fidelity.com's beneficiary management portal with electronic signature, or by mail. The form permits per-stirpes and per-capita distribution language, permits naming of a trust with automatic look-through to the trust beneficiaries under Treas. Reg. §1.401(a)(9)-4(f) — the see-through trust framework covered in our see-through trust guide — permits naming of a charity, permits unlimited primary and contingent successors, and can be updated as often as the beneficiary chooses without a re-signature ceremony.^[4]

Post-death service escalation. Fidelity maintains a dedicated Retirement Distributions and Inheritance team, reachable at a dedicated phone number (separate from the general customer service line) with typical wait times under 5 minutes and specialists cross-trained on IRC §408(d)(3)(C), the four EDB categories, and Rev. Proc. 2024-4 PLR procedure. Accounts above $250,000 are eligible for the Fidelity Wealth Management service tier with an assigned dedicated relationship specialist, though the specialist relationship does not carry an AUM fee for beneficiaries who decline advisory services.

In-kind transfer capability. Full ACAT-in for US-listed stocks, ETFs, options, most mutual funds (including Vanguard funds, Schwab funds, and third-party fund families), and Treasury securities. Some non-partner mutual funds may be received but not accept additional purchases at Fidelity; the beneficiary can either liquidate at their discretion or hold to maturity.

Fees. $0 maintenance fee on retail inherited IRAs. $0 commissions on US-listed stocks and ETFs. $0 on Fidelity mutual funds and ~3,300 no-transaction-fee funds. $0-$49.95 on transaction-fee mutual funds (fund-family dependent). $0 for full ACAT-out to another custodian.

Weakness. Fidelity's online platform is optimized for the beneficiary's own trading experience rather than for the intergenerational estate context — the successor beneficiary designation portal is buried three clicks deep from the account overview page, and the interface does not proactively prompt the beneficiary to file the successor designation at account opening.

Charles Schwab

Charles Schwab is the second-largest US retail brokerage custodian, holding approximately $9.4 trillion in client assets across roughly 36 million brokerage accounts as of Q1 2026 following the completion of the TD Ameritrade integration in 2024.^[8] The inherited-IRA product is administered by Charles Schwab & Co. Inc. as an account subtype within the standard retail brokerage platform.

Titling convention. Schwab's titling for an inherited IRA is "[Deceased Owner], IRA, [Beneficiary Name] Bene" — a compact variant of the IRS model form that includes the deceased owner's name and a "Bene" (beneficiary) suffix. Schwab account statements print the full title with a "Beneficiary of [Deceased]" secondary line for clarity. The titling is applied at account setup through an automated workflow parallel to Fidelity's, with the same low error rate.

Successor beneficiary form. Schwab's inherited-IRA beneficiary designation form is IRA1002 (2023 revision), submittable online through Schwab.com's beneficiary center for natural-person designations, or by mail for trust-as-beneficiary and charity-as-beneficiary designations. Schwab supports per-stirpes and per-capita language and permits contingent successor designation, but requires wet-signature submission for any designation involving a trust.^[9]

Post-death service escalation. Schwab maintains an Estate and Trust Services team reachable at a dedicated phone number with typical wait times under 5 minutes. Accounts above $500,000 are eligible for the Schwab Private Client service tier with an assigned dedicated financial consultant; accounts above $1,000,000 are eligible for Schwab Private Wealth Services. The Estate and Trust Services team is the load-bearing service tier for inherited-IRA titling corrections and successor designation disputes and is generally regarded as comparable to Fidelity's Retirement Distributions team in specialty depth.

In-kind transfer capability. Full ACAT-in for US-listed securities, options, and most mutual funds. Post-TD Ameritrade integration, Schwab also carries the full thinkorswim active-trading platform for beneficiaries who want option strategies or algorithmic trading capability on the inherited account — a differentiator from Fidelity, Vanguard, and Merrill.

Fees. $0 maintenance fee on retail inherited IRAs. $0 commissions on US-listed stocks and ETFs. $0 on Schwab mutual funds and ~4,000 no-transaction-fee funds. Up to $49.95 on transaction-fee mutual funds. $50 partial-transfer or $75 full-transfer ACAT-out fee.

Weakness. The TD Ameritrade integration completed in 2024 but some legacy TDA accounts still surface minor UI inconsistencies in the successor beneficiary portal. Beneficiaries who inherited from an account originally opened at TD Ameritrade should confirm the successor designation is properly migrated after the integration.

Vanguard

Vanguard is the third-largest US retirement account custodian by IRA assets, with approximately $9.3 trillion in worldwide AUM including approximately $2.4 trillion in IRA and defined-contribution assets as of Q1 2026.^[10] Vanguard's structural difference from Fidelity and Schwab — its mutual-owner structure, in which the fund shareholders collectively own the management company — produces the lowest expense ratios in the industry on Vanguard's own mutual funds and ETFs, which is the primary reason many beneficiaries transfer inherited IRAs to Vanguard.

Titling convention. Vanguard's titling is "[Beneficiary Name], beneficiary of [Deceased Owner Name], deceased [date]" — a beneficiary-first variant that reverses the order of Fidelity and Schwab but includes all four required elements (deceased owner name, death indicator, "beneficiary" language, beneficiary name). Vanguard's automated workflow applies the titling at account setup with the same low error rate as Fidelity and Schwab.

Successor beneficiary form. Vanguard's inherited-IRA beneficiary designation form is Form VG-BEN-INHERIT (2023 revision), fully online through Vanguard.com's beneficiary center with electronic signature. The form supports per-stirpes and per-capita language but limits the beneficiary count to five per level (primary, contingent, tertiary) — a constraint that rarely matters for individual beneficiaries but can be a limitation for beneficiaries with large blended families or complex trust structures. Trust-as-beneficiary and charity-as-beneficiary designations are supported online for common cases.^[11]

Post-death service escalation. Vanguard maintains an Inheritance and Estate Services team reachable at a dedicated phone number, though wait times have historically been longer than Fidelity or Schwab (typical wait 15-25 minutes at peak). Vanguard's service model relies more heavily on the online portal and less on the phone specialist tier than Fidelity or Schwab, which suits self-directed beneficiaries but is a weaker fit for beneficiaries who prefer to resolve complex questions through a live specialist.

In-kind transfer capability. Full ACAT-in for US-listed stocks, ETFs, and Vanguard mutual funds. Non-Vanguard mutual funds may be received but often cannot accept additional purchases, and Vanguard imposes a per-transaction fee (up to $20) on non-Vanguard mutual fund purchases in an inherited IRA. Beneficiaries transferring an account holding primarily non-Vanguard mutual funds should typically liquidate before the transfer.

Fees. $0 maintenance fee on retail inherited IRAs above $5,000,000 in Vanguard mutual funds and ETFs; standard $25/year fee waived when the beneficiary opts into electronic statements. $0 commissions on US-listed stocks and ETFs. $0 on Vanguard mutual funds. Up to $20 per transaction on non-Vanguard mutual funds. $0 for full ACAT-out.

Weakness. The phone specialist wait times and the more automated service model make Vanguard a weaker fit for beneficiaries who need high-touch handling of a complex successor designation or a titling correction. Vanguard's product platform is the strongest for buy-and-hold beneficiaries and the weakest for beneficiaries who want active trading or a wide non-partner mutual-fund selection.

Merrill Edge

Merrill Edge is the retail self-directed brokerage arm of Bank of America Corporation's Merrill Lynch Wealth Management business, holding approximately $470 billion in client assets across roughly 4 million accounts as of Q1 2026.^[12] Merrill Edge is a natural default for beneficiaries who already have a Bank of America banking relationship — deposits, credit cards, mortgages — and want consolidated statements and Preferred Rewards program tier benefits that combine banking and brokerage balances.

Titling convention. Merrill's titling for an inherited IRA is "[Beneficiary Name] IRA BDA [Deceased Owner Name]" — where "BDA" stands for "Beneficiary Distribution Account" — plus a secondary account descriptor line noting the deceased owner's name and date of death. The titling meets IRS model form requirements but the "BDA" abbreviation is less immediately readable than Fidelity's "as beneficiary" or Schwab's "Bene" convention.

Successor beneficiary form. Merrill's inherited-IRA beneficiary designation form is CMA-INH-BENE, submittable primarily by mail for all designations involving a trust or a charity, and through the Merrill Edge portal for natural-person designations only. The paper-only requirement for trust designations is a friction point Fidelity, Schwab, and Vanguard have all eliminated.^[13]

Post-death service escalation. Merrill Edge relies on the shared Merrill Lynch Estate Services team for inherited-IRA specialty handling. The team's phone wait times and specialty depth are generally comparable to Vanguard's — competent but less immediately reachable than Fidelity's or Schwab's dedicated inheritance desks. Merrill Edge clients with more than $250,000 in combined Bank of America and Merrill assets qualify for Preferred Rewards Platinum tier with priority customer service that reduces wait times.

In-kind transfer capability. Full ACAT-in for US-listed stocks, ETFs, and options. Mutual fund handling is more restricted than Fidelity/Schwab/Vanguard — Merrill Edge does not carry every fund family, and certain non-partner funds may need to be liquidated before transfer.

Fees. $0 maintenance fee on retail inherited IRAs. $0 commissions on US-listed stocks and ETFs. Up to $19.95 on transaction-fee mutual funds. $49.95 full-transfer ACAT-out fee — higher than the free-transfer-out fees at Fidelity and Vanguard.

Weakness. The paper-only successor designation for trust and charity beneficiaries is a real drawback for estate-plan-heavy beneficiaries. The ACAT-out fee is meaningful for beneficiaries who later decide to consolidate at another custodian.

Empower Retirement

Empower is the second-largest US institutional retirement plan record-keeper, administering approximately 89,000 defined-contribution plans and $1.6 trillion in retirement assets as of Q1 2026 following the acquisitions of Prudential's full-service retirement business (2022), MassMutual's retirement plan business (2020), and the Great-West Financial retirement business (2014).^[14] Empower is the correct default only when the deceased owner's account was already at Empower's institutional side and the beneficiary wants to preserve continuity — otherwise, Empower's institutional-record-keeping model produces meaningful friction compared to the retail brokerage model used by Fidelity, Schwab, Vanguard, and Merrill.

Titling convention. Empower's titling varies by the original plan document — some plans use "Inherited [Plan Name] Account for [Beneficiary Name] as beneficiary of [Deceased Owner]," while others use variants specified by the plan sponsor. All variants include the deceased owner's name and beneficiary language, but the specific format is not standardized across Empower's institutional book.

Successor beneficiary form. Empower's institutional-side successor designation depends heavily on the plan document. Some plans permit only a natural-person primary successor; some require plan-sponsor approval for a trust designation; some require the account to be rolled to Empower's retail brokerage side (Empower Personal Dashboard) before more complex designations can be filed. The variability makes Empower's institutional side the weakest of the five majors for beneficiaries with any successor designation complexity.^[14]

Post-death service escalation. Empower's institutional-side service model routes beneficiaries through the plan record-keeper's general call center, which is staffed by generalists trained on the plan document but not necessarily on IRC §408(d)(3)(C) or the four EDB categories. Escalation to a competent inherited-IRA specialist is slower than at any of the retail-brokerage majors.

In-kind transfer capability. Empower's institutional side often requires liquidation to cash before the account is opened at the new plan or the retail brokerage side, which can force realization of the deceased's pre-death gains in the account. Empower's retail brokerage side (Empower Personal Dashboard, formerly Personal Capital) has better in-kind capability but is a newer platform with less depth than Fidelity/Schwab/Vanguard.

Fees. Empower's institutional side can carry plan-level administration fees ranging from $30 to $150 per year depending on the terms negotiated by the former plan sponsor. Empower's retail brokerage side waives maintenance fees on retail inherited IRAs. $0 commissions on US-listed stocks and ETFs on the retail brokerage side.

Weakness. The institutional-side administration model, the plan-document variability, and the sometimes-mandatory liquidation on transfer all make Empower's institutional side the weakest of the five majors for a beneficiary who inherits an account there and does not have a specific reason to keep it. The retail brokerage side is competitive but does not yet match the depth of the Fidelity/Schwab platforms.

Head-to-head decision matrix

Transfer mechanics: moving an inherited IRA to a different custodian

A beneficiary who decides the default custodian is not the right long-term choice moves the account through a trustee-to-trustee transfer — never through a 60-day rollover, and never by taking a distribution and depositing it into a new account. IRC §408(d)(3)(C) forecloses any rollover option for non-spouse beneficiaries, and any check made payable to the beneficiary triggers a deemed distribution of the entire account balance under §408(d)(1).^[3] The correct sequence is:

1. Open the receiving inherited-IRA account first. The new custodian's account must be opened with the correct "[Deceased Owner], deceased [date], IRA FBO [Beneficiary], as beneficiary" title before any transfer request is submitted. The receiving custodian will require the death certificate, the deceased owner's original IRA account agreement or beneficiary designation record, and the beneficiary's own identity documentation.
2. File the ACAT (Automated Customer Account Transfer) request. The receiving custodian initiates the ACAT request against the sending custodian using the sending custodian's account number. Full or partial transfer is available; full transfer is generally preferable to avoid maintaining two accounts. In-kind transfer of individual securities takes 3-8 business days once submitted.
3. Take the year's RMD from the sending custodian before the transfer settles. The receiving custodian will not carry forward the sending custodian's RMD calculation. If the year's RMD has not been taken at the time of transfer, the beneficiary must take it from the sending custodian before the transfer settles or from the receiving custodian after settlement — but the receiving custodian's records may not immediately reflect the full year's divisor calculation, creating a risk of missed RMD.
4. Confirm the receiving custodian's title on the first statement. Once the transfer settles, confirm the account title on the receiving custodian's first statement matches the required "[Deceased Owner], deceased [date], IRA FBO [Beneficiary], as beneficiary" format. If the title is incorrect, escalate to the receiving custodian's inherited-IRA specialty desk immediately — the correction is easiest within the first 30 days.
5. File the successor beneficiary designation on the new account. The successor designation does not carry over from the sending custodian. It must be filed anew on the receiving custodian's specific inherited-IRA beneficiary designation form.

Three worked case studies

Case 1: Alina — Regional bank default, $420,000 balance

Alina, age 44, is a physician in Missouri inheriting a $420,000 traditional IRA from her mother Ruth who died in March 2026. Ruth held her IRA at a mid-size regional bank in St. Louis that offered a limited menu of proprietary mutual funds and no self-directed brokerage. The bank's inherited-IRA administration team consists of two trust officers, neither of whom is trained specifically on the SECURE Act 10-year rule or the July 2024 final regulations under TD 10001.

Alina calls the bank's trust department and requests information about the inherited-IRA account setup. The trust officer confirms the account can be opened at the bank but describes the annual advisory fee as 0.85% of assets on the proprietary mutual fund portfolio — significantly higher than Alina expected, and there is no menu option to hold individual securities. Alina decides to transfer to Fidelity, where she already holds her own IRA and Roth IRA.

Alina opens a Fidelity inherited-IRA account (correctly titled "Ruth K. Petrov, Deceased 3/14/2026, IRA FBO Alina M. Petrov, as beneficiary") on May 12, 2026, initiates an ACAT-in request against the regional bank, takes the 2026 RMD ($15,800 based on Ruth's 2025 year-end balance and Alina's Single Life divisor of 41.5) from the regional bank before the transfer settles, and completes the transfer by June 3, 2026. The proprietary mutual funds liquidate to cash during the ACAT (they cannot transfer in-kind to Fidelity's platform), and Alina reinvests at Fidelity into a low-cost Fidelity index fund portfolio (FZROX + FZILX + FXNAX at zero expense ratio for the domestic and international equity sleeves).

The fee savings over the 10-year window at 0.85% vs 0.00% on the $420,000 opening balance, growing at 5% annually with $30,000-$50,000 annual distributions, is approximately $18,500 in preserved value at the tenth-year distribution — plus the qualitative benefit of a competent inherited-IRA specialty desk at Fidelity, the online successor beneficiary designation portal, and the automated RMD service. Total cost of the transfer: 4 hours of Alina's time, one certified death certificate copy ($15), and zero tax liability.

Case 2: Marcus — Empower institutional-side complication, $650,000 balance

Marcus, age 52, is a software engineer in Washington state inheriting a $650,000 401(k) balance from his father James who died in July 2026. James's 401(k) was administered by Empower as the plan record-keeper for James's former employer, a mid-size manufacturing company. The plan document permits both direct rollover to an inherited IRA and a five-year distribution option (which James elected on his beneficiary designation years earlier).

Marcus contacts Empower and learns that (a) if he leaves the account at Empower's institutional side, he is bound by the plan's five-year distribution option under the plan document, forcing full distribution by December 31, 2031 — five years earlier than the statutory 10-year window under IRC §401(a)(9)(H); (b) the plan carries a $85/year administrative fee assessed against his portion of the account; (c) the plan's investment menu is limited to twelve target-date funds and eight core funds, with no ability to hold individual securities.

Marcus's CPA advises rolling the balance to an inherited IRA at a retail custodian, which is permitted under §401(a)(9)(H) and preserves the full 10-year window rather than the plan's five-year default. Marcus opens a Charles Schwab inherited-IRA account (correctly titled "James R. Ochoa, IRA, Marcus J. Ochoa Bene") on August 8, 2026, initiates a direct rollover request from Empower to Schwab, and completes the transfer by September 22, 2026. The account arrives at Schwab as cash (Empower's institutional side liquidated the target-date funds during the rollover, as anticipated), and Marcus rebuilds the portfolio at Schwab into a mix of Schwab index funds (SWTSX + SWISX + SCHZ) and individual Treasury bills for the near-term distribution years.

The value preserved by rolling to Schwab includes: (a) the additional 5 years of tax-deferred growth on the account balance ($650,000 growing at 5% for 5 additional years = approximately $180,000 in additional pre-distribution balance), (b) the tax arbitrage of spreading distributions over 10 years vs 5 years, which for Marcus's marginal-bracket profile is approximately $47,000 in reduced federal tax over the decade, and (c) the elimination of the $85/year Empower administration fee. Total transferred value: approximately $225,000 over the full decade.

Case 3: Priya — Vanguard-to-Fidelity for successor complexity, $290,000 balance

Priya, age 61, is a retired teacher in New Jersey inheriting a $290,000 traditional IRA from her aunt Nadia who died in November 2025. Nadia held her IRA at Vanguard, and Priya opened a Vanguard inherited-IRA account (correctly titled per Vanguard's convention) in December 2025.

Priya's own estate plan includes a see-through trust drafted under Treas. Reg. §1.401(a)(9)-4(f) that names her four adult children as remainder beneficiaries with per-stirpes distribution to their descendants if a child predeceases Priya. Priya attempts to file the successor beneficiary designation on Vanguard's VG-BEN-INHERIT form in January 2026 and discovers that Vanguard's form limits the beneficiary count to five per level and does not support the per-stirpes cascade language her trust attorney drafted.

Priya's trust attorney recommends transferring to Fidelity, whose Form FBS-INH-BEN-DES supports both the see-through trust designation and the per-stirpes cascade language directly. Priya opens a Fidelity inherited-IRA account (correctly titled "Nadia K. Chen, Deceased 11/18/2025, IRA FBO Priya M. Sharma, as beneficiary") on February 15, 2026, initiates an ACAT-in request against Vanguard, and completes the transfer by March 7, 2026. Vanguard's index funds transfer in-kind to Fidelity, and Priya files the successor beneficiary designation on the Fidelity form on March 10, 2026 with the full trust-and-per-stirpes language.

The value preserved by transferring is not a fee number — the fee differential between Vanguard and Fidelity on this account holding is essentially zero — but the estate-planning value of a correctly-drafted successor designation. If Priya had died in 2028 with the incomplete Vanguard designation on file, the account would have cascaded through Priya's probate estate, potentially forcing the 5-year rule under IRC §401(a)(9)(B)(ii) and incurring probate fees estimated at $8,000-$15,000 in New Jersey. The transfer preserved the intended intergenerational cascade.

Six most-common mistakes

1. Defaulting to the deceased's custodian without evaluating alternatives. The deceased's custodian is the correct choice roughly 60% of the time, but the beneficiary should confirm that specifically rather than adopting it as an unexamined default. Ask each candidate custodian the six questions from the FAQ before opening the account.
2. Attempting a 60-day rollover instead of a trustee-to-trustee transfer. IRC §408(d)(3)(C) forecloses any rollover option for non-spouse beneficiaries. A check made payable to the beneficiary triggers a deemed distribution of the entire account balance under §408(d)(1). Always trustee-to-trustee.
3. Not confirming the receiving custodian's title on the first statement. A titling mistake at the receiving custodian is as damaging as one at the sending custodian. Read the first statement carefully and escalate to the specialty desk immediately if the title does not include the deceased owner's name and "as beneficiary" language.
4. Missing the year's RMD during the transfer window. Take the RMD from the sending custodian before initiating the ACAT, or take it from the receiving custodian after settlement — never assume it will be taken automatically at both.
5. Failing to re-file the successor beneficiary designation on the new account. The successor designation does not carry over from the sending custodian. It must be filed anew on the receiving custodian's specific inherited-IRA beneficiary form.
6. Consolidating multiple inherited IRAs from different decedents into one account. Not permitted under IRC §408(d)(3)(C). Each decedent's inherited IRA must remain in its own account with its own decedent identifier and its own 10-year clock or lifetime-stretch schedule. See the custodian titling failure modes guide for the full failure taxonomy.

State-tax overlay for the distribution years

The custodian choice does not affect state-tax exposure on the annual distributions during the 10-year window — that depends entirely on the beneficiary's state of residence at the time of each distribution. But the custodian's flexibility in scheduling distributions across the calendar year, offering partial-Roth-conversion services (not permitted for non-spouse inherited IRAs under §408A(d)(3)(C) but can matter for surviving-spouse-rolled accounts), and providing state-tax withholding elections can produce meaningful savings for beneficiaries in Tier 3 and Tier 4 states.

Beneficiaries considering a state relocation during the 10-year window should coordinate the distribution schedule with the relocation date — the state-tax character of a distribution is determined by the beneficiary's state of residence on the date of the distribution, not by the state of residence at the time of inheritance. See our state retirement income taxation 2026 field guide for the full state-by-state framework.

8-item action checklist

For a primary beneficiary in the first 30 days after inheriting an IRA, before opening the successor inherited-IRA account at any custodian:

1. Confirm the deceased owner's current custodian and account balance. Request a copy of the deceased's most recent statement and confirm the current custodian's name, the account balance as of the most recent statement date, and the current investment mix.
2. Ask the deceased's custodian the six questions. Titling convention, successor form name and capabilities, specialty desk phone number, fee schedule, RMD administration, and dedicated inherited-IRA service. Get answers in writing where possible.
3. Ask the same six questions of one or two alternative retail custodians. Fidelity, Schwab, and Vanguard are the three natural comparisons for most beneficiaries; Merrill Edge is a fourth for Bank of America clients; Empower's retail brokerage side is a fifth if the deceased's account was already at Empower.
4. Compare the six-variable scorecard. Titling correctness, successor form quality, post-death service escalation, in-kind transfer capability, fee schedule, and RMD administration. Fee variance is a small factor at retail balances; service quality and successor form flexibility are the larger factors for most beneficiaries.
5. Confirm the year's RMD status. Take the year-of-death RMD (if the deceased had reached their Required Beginning Date) from the sending custodian before initiating any transfer. This is the highest-risk moment in the transfer sequence.
6. Open the receiving inherited-IRA account with correct titling before submitting the ACAT. The receiving custodian must open the account with the correct "[Deceased Owner], deceased [date], IRA FBO [Beneficiary], as beneficiary" title before any transfer request is filed.
7. File the successor beneficiary designation immediately on account opening. Do not wait until after the transfer settles. Every business day without a successor designation on file increases the risk that the primary dies with no successor, cascading the account to probate.
8. Confirm the first statement's title. Read the receiving custodian's first statement carefully and escalate to the specialty desk if the title does not include the deceased owner's name and "as beneficiary" language.
