How to Maximize Your Connecticut Tax Refund
1. Contribute to Retirement Accounts
Traditional 401(k) contributions reduce your taxable income dollar-for-dollar. For 2025, you can contribute up to $23,500 ($31,000 if 50+). Traditional IRA contributions may also be deductible up to $7,000 ($8,000 if 50+).
2. Maximize HSA Contributions
If you have a high-deductible health plan, contribute to an HSA. For 2025, limits are $4,300 (self) or $8,550 (family). HSA contributions are tax-deductible, grow tax-free, and withdrawals for medical expenses are tax-free.
3. Claim All Eligible Credits
Don't miss these valuable credits: Child Tax Credit ($2,000/child), Earned Income Tax Credit (up to $7,830), Education Credits (up to $2,500 AOTC), Child & Dependent Care Credit (up to $2,100).
4. Consider Itemizing Deductions
If your itemized deductions exceed the standard deduction ($14,600 single / $29,200 married), itemize. Common deductions: mortgage interest, state/local taxes (SALT, capped at $10,000), charitable contributions, medical expenses exceeding 7.5% of AGI.
5. Connecticut State-Specific Strategies
With Connecticut's progressive brackets (3-6.99%), reducing taxable income through deductions can move you into a lower bracket. Even small contributions to retirement accounts can yield significant state tax savings.
