Self-employed workers in Maine must pay both federal estimated taxes to the IRS and state estimated taxes to the Maine Revenue Services. Maine has a progressive income tax with 3 brackets and rates ranging from 5.8% to 7.15%. If you expect to owe $1,000 or more in Maine state income tax after withholding and credits, you must make quarterly estimated payments using Form 1040ES-ME.
Maine has relatively high income tax rates, but offers a generous standard deduction and personal exemption. The state also provides a tax credit for property taxes paid, which can benefit self-employed individuals who work from home.

All self-employed workers must pay federal self-employment (SE) tax of 15.3% on 92.35% of net earnings. This consists of 12.4% for Social Security (on earnings up to $184,500 in 2026) and 2.9% for Medicare (no cap). An additional 0.9% Medicare surtax applies to earnings above $200,000 (single filers).
Both Maine and federal estimated tax payments follow the same quarterly schedule:
| Quarter | Income Period | Due Date |
|---|---|---|
| Q1 | January 1 – March 31 | April 15, 2026 |
| Q2 | April 1 – May 31 | June 15, 2026 |
| Q3 | June 1 – August 31 | September 15, 2026 |
| Q4 | September 1 – December 31 | January 15, 2027 |
To avoid underpayment penalties, pay at least 100% of your prior-year tax liability (or 110% if your AGI exceeds $150,000) spread across four equal payments, or at least 90% of your current-year tax. You can deduct 50% of your self-employment tax from your adjusted gross income, reducing both your federal and Maine taxable income.
