1099 Quarterly Taxes in Maine (2025-2026)
If you're self-employed in Maine — freelancer, contractor, gig worker, or single-member LLC — you owe quarterly estimated taxes to two agencies: the IRS (federal) and Maine Revenue Services (state). Maine's top marginal rate is 7.15%, applied progressively. Getting your estimates right matters because under-payment penalties stack on top of the actual tax owed.
Maine state income tax (2025)
Maine uses a progressive bracket system on top of federal tax. For single filers in 2025:

| $26,800 – $63,450 | 6.75% |
| $63,450+ | 7.15% |
How to pay Maine estimated taxes
Federal estimated tax due dates (April 15, June 16, September 15, 2026, and January 15, 2027) apply to your Maine state estimated payments as well — most states piggyback on the federal schedule. Pay Maine taxes through the Maine Revenue Services's online portal: www.maine.gov/revenue. You can also mail Form 1040ES-ME with a check.
Maine-specific quirk freelancers miss
Maine has only three brackets but the lowest is already 5.8% — making it among the highest 'starting' rates in the country. Self-employed Mainers should plan accordingly even at modest income levels.
