Maine Capital Gains Tax Rate (2026)
Maine capital gains tax overview
Three brackets: 5.8%, 6.75%, 7.15%. No preferential capital gains rate.
Federal + Maine combined rates
Your total capital gains tax bill includes both layers — federal and state. Here is what a Maine investor pays in 2026 for long-term gains:
| Federal Long-Term Rate | Maine State Rate | Combined Rate | Plus NIIT (if applicable) |
|---|---|---|---|
| 0% | 7.15% | 7.15% | 10.9% |
| 15% | 7.15% | 22.1% | 26.0% |
| 20% | 7.15% | 27.1% | 31.0% |
The NIIT (Net Investment Income Tax) adds an extra 3.8% for taxpayers whose MAGI exceeds $200,000 (single) or $250,000 (married filing jointly). It is a federal tax only — Maine does not have an equivalent.
How Maine compares to other states
Maine's top rate of 7.15% places it in the upper-middle tier of state capital gains taxation. For comparison:
- Zero-tax states (FL, TX, NV, etc.): 0% — total with 15% federal = 15%
- Low-rate states (AZ, IN, PA): 2.5–3.1% — total with 15% federal = 17.5–18.1%
- Maine: 7.15% — total with 15% federal = 22.1%
- High-rate states (NY, NJ): 10.75–10.9% — total with 15% federal = ~26%
- California: 13.3% — total with 15% federal = 28.3%
Tax-reduction strategies for Maine residents
With a top state rate of 7.15%, minimizing capital gains tax is particularly important in Maine. Key strategies:
- Hold over 1 year for long-term federal rates (0/15/20%). Maine does not offer a preferential state rate, but federal savings alone are often 7–17%.
- Tax-loss harvesting: Offset your gains with losses realized in the same year. A $20,000 loss offsets $20,000 of gains dollar-for-dollar, saving up to 27% ($5,430) on that $20,000 at top rates.
- 0% bracket planning: In lower-income years (retirement, sabbatical, between jobs), realize gains at the federal 0% rate. You still owe Maine state tax, but eliminating the federal component is significant.
- Donate appreciated stock directly to charity or a donor-advised fund to avoid capital gains tax entirely while generating a charitable deduction for the full fair market value.
- Installment sales: If selling a business or real estate, structuring as an installment sale spreads the gain over multiple years, potentially keeping each year's gain in a lower bracket.
Detailed Maine capital gains tax rules
Tax history and legal basis
Maine taxes capital gains as ordinary income using a progressive system with a top rate of 7.15% on income over $58,050 (single) for 2026.
Exemptions and special treatment
Maine offers a capital gains exclusion of up to $250,000 on gains from the sale of a Maine business if the business was owned for 5+ years and employed Maine residents. This makes Maine one of the most favorable states for business exit capital gains. General investment gains receive no preferential treatment.
Filing requirements
File Form 1040ME (resident). Maine largely conforms to federal AGI as the starting point. Estimated payments required if owing $1,000+. Filing deadline is April 15.
Recent changes and legislative updates
Maine's top rate of 7.15% has remained stable. The state's $250,000 business sale exclusion is one of the most generous in New England and significantly reduces the tax burden for entrepreneurs selling their businesses. This provision is specifically designed to encourage business formation and retention in Maine.
Worked example: $50,000 capital gain in Maine
Here's exactly what a Maine resident would owe on a $50,000 long-term capital gain with $80,000 in other income (single filer, 2026):
| Component | Amount | Notes |
|---|---|---|
| Capital gain | $50,000 | Long-term (held over 1 year) |
| Federal tax (15%) | −$7,500 | Based on $80,000 ordinary income + gain |
| Maine state tax (7.15%) | −$3,575 | Applied to the full gain amount |
| Total tax owed | −$11,075 | Federal + state combined |
| You keep | $38,925 | 77.8% of your gain |
After both federal and Maine state tax, you keep $38,925 of your original $50,000 gain. The effective combined rate is 22.1%. This is significantly higher than the national average — consider tax-loss harvesting or timing strategies to reduce your bill.
Frequently asked questions — Maine
Does Maine tax short-term and long-term gains differently?
No — Maine taxes both short-term and long-term capital gains as ordinary income at the same rates as wages. There is no state-level preferential rate for patience. The federal system, however, taxes long-term gains at 0/15/20% vs. up to 37% for short-term — a significant difference that applies regardless of state.
Do I need to file a Maine tax return if I only have capital gains?
If you have capital gains income and meet Maine's filing threshold, you are required to file a Maine state income tax return. The threshold is typically similar to the standard deduction amount — check the ME Department of Revenue for the current year's filing requirements.
What if I moved to Maine mid-year?
If you moved to Maine during the year, you are a part-year resident. Maine generally taxes capital gains realized while you were a Maine resident. Gains realized before you moved may be taxable by your prior state. Keep detailed records of when each sale occurred relative to your move date.
