Short-Term vs. Long-Term Capital Gains

Short-term gains (assets held less than 1 year) are taxed at your ordinary income tax rate — which can be as high as 37% federally plus 7.15% in Maine. Long-term gains (assets held 1+ years) receive preferential federal rates of 0%, 15%, or 20%, but Maine does not offer a preferential state rate — gains are taxed as ordinary income.

5 Strategies to Reduce Capital Gains Tax in Maine

Hold investments for 1+ years — Long-term gains qualify for 0/15/20% federal rates instead of up to 37%
Tax-loss harvesting — Sell losing investments to offset gains (up to $3,000 excess losses deductible)
Use tax-advantaged accounts — 401(k), IRA, Roth IRA, HSA shield gains from taxation
Qualified Opportunity Zones — Defer and potentially reduce capital gains by investing in QOZ funds
Consider your timing — Sell in years when your income is lower to stay in a lower federal bracket
