Individuals

Maine has a graduated individual income tax (about 7.15% at the top). Residents generally file Form 1040ME and start from their federal income.

Nonresidents and part-year residents who earn income from Maine sources (for example wages for work performed in Maine, rental property or a business here) generally file the nonresident or part-year version of the return or a schedule. Your home state normally gives a credit for tax paid to Maine, so the same income is rarely taxed twice.

Good to know: Maine has no local sales taxes, but has meals and lodging tax rates of its own.

Businesses

Entity-level taxes: Corporate income tax, graduated, about 8.93% at the top.

Pass-through businesses. S corporations, partnerships and most LLCs pass income to their owners, who report it on personal returns. Many states, including a large number of those that tax income, offer an elective pass-through entity tax (PTET) that can help work around the federal limit on deducting state taxes. Ask us whether it fits Maine and your situation.

Sales tax. About 5.5% state rate. After the Wayfair decision, out-of-state sellers can owe sales tax once their sales into Maine pass the state's threshold, even with no office there.

Payroll. Employers must register for state income tax withholding (where the state has an income tax) and for state unemployment insurance before the first payroll, and report new hires. Workers' compensation insurance is also required in most cases.

Annual filings. Most states also require corporations and LLCs to file a yearly report or pay a fee to the Secretary of State.

Working in more than one state

Maine is not commonly listed as having wage reciprocity with other states, so people who live in one state and work in another usually file nonresident returns and claim a credit at home.

Working or living in more than one state, or moving during the year? See our multi-state tax guide.

Common questions

What is the Maine income tax rate for 2026?

Maine has graduated rates with a top rate of about 7.15%. Rates, brackets and credits change, so confirm with the Maine Revenue Services.

Which form do I file for Maine income tax?

Residents generally file Form 1040ME. Nonresidents and part-year residents use the nonresident or part-year version or a schedule. The state agency's website has the current forms and instructions.

Do I need to file a Maine return if I live in another state?

If you earned income from Maine sources (wages for work performed here, rental property, or a business or partnership interest), you may need to file in Maine even if you live elsewhere. Your home state usually gives a credit for tax paid to another state.

Does Maine have reciprocity with other states?

Maine is not commonly listed as having wage reciprocity. Reciprocity applies only to wages and there are exceptions, so confirm before you stop withholding.

What business taxes apply in Maine?

Corporate income tax, graduated, about 8.93% at the top. Sales tax, payroll withholding and unemployment insurance may also apply.

  • You can put up to $24,500 of your pay into a 401(k), 403(b) or TSP in 2026. At 50 or older you can add $8,000, and at ages 60 to 63 you can add $11,250 (up to $35,750 in all). IRS: 2026 retirement limits →
  • Work for yourself with no employees? A solo 401(k) lets you save $24,500 as the "employee" and add an employer contribution on top, for up to $72,000 in total before catch-up. A SEP-IRA has the same top limit. IRS: One-participant 401(k) plans →
  • A SEP-IRA can be opened and funded as late as your tax filing deadline, including extensions. That makes it one of the best last-minute ways for a self-employed person to lower the tax bill. IRS: SEP plans →
  • You can put $7,500 in an IRA for 2026, or $8,600 if you are 50 or older, and you have until the April 2027 filing deadline to do it. IRS: IRA contribution limits →
  • A SIMPLE IRA is an easy retirement plan for a small business. Employees can defer $17,000 in 2026, $21,000 at 50 or older, and $22,250 at ages 60 to 63. IRS: SIMPLE IRA plans →
  • An HSA is taxed in your favor three times: money goes in tax-free, grows tax-free and comes out tax-free for medical costs. The 2026 limit is $4,400 for self-only and $8,750 for family coverage, plus $1,000 if you are 55 or older. IRS: Publication 969 →
  • A defined benefit or cash balance plan can let a business owner with steady, high income put away far more than a 401(k) allows, especially after 50. The yearly benefit limit for 2026 is $290,000. IRS: Defined benefit plans →
  • New in 2026: if your Social Security wages from the employer that sponsors your 401(k) were over $150,000 in 2025, your catch-up contributions must go in as Roth (after-tax) money. IRS: 2026 retirement limits →
  • If your income is modest, the saver's credit can cut your tax bill by up to $1,000 ($2,000 for a couple) just for saving for retirement. For 2026 it reaches incomes up to $40,250 single and $80,500 joint. IRS: Saver's credit →
  • When you work for yourself you pay both halves of Social Security and Medicare tax: 15.3% on net earnings up to $184,500 in 2026, and 2.9% above that. Half of it is deductible on your return. IRS: Self-employment tax →
  • The qualified business income deduction can take up to 20% off the tax on pass-through business income. The 2025 law made it permanent and added a $400 minimum deduction if you have at least $1,000 of qualified income. IRS: QBI deduction →
  • Estimated taxes are due four times a year: April 15, June 15, September 15 and January 15. Paying 100% of last year's tax (110% if your income was over $150,000) usually protects you from the underpayment penalty. IRS: Estimated taxes →
  • The business mileage rate rose to 76 cents a mile on July 1, 2026 (it was 72.5 cents from January to June). A simple log of dates, miles and purpose is what turns miles into a deduction. IRS: Standard mileage rates →

  • If you are self-employed, the health insurance premiums you pay for yourself, your spouse and your dependents may be deductible even if you do not itemize, up to your net profit. IRS: Self-employed health insurance →

  • S corporation owners who work in the business must pay themselves a reasonable salary. Too low, and the IRS can recharacterize distributions as wages and charge payroll tax and penalties. IRS: S corporation compensation →
  • Illinois lets partnerships and S corporations elect to pay Illinois tax at the entity level. The owners can then get a federal deduction that works around the $40,400 cap on state and local taxes. Illinois tax guide →
  • Startup costs for a new business: up to $5,000 can be deducted in the first year and the rest over 15 years, so keep every receipt from before opening day. IRS: Publication 535 →

  • Late payroll tax deposits can bring penalties of up to 15%. Payroll taxes are due on a fixed schedule, and the penalty grows the longer a deposit is late. IRS: Failure to deposit penalty →

  • Not filing costs ten times more than not paying: 5% of the unpaid tax per month (up to 25%) against 0.5% per month. If you cannot pay, still file on time. IRS: Failure to file penalty →
  • An extension to file is not an extension to pay. Pay what you expect to owe by the original due date to avoid penalties and interest. IRS: Extension to file →
  • You may qualify for IRS first-time penalty abatement if you filed and paid on time for the past three years. Ask before you pay a penalty. IRS: Penalty relief →
  • A Notice of Deficiency gives you 90 days (150 if you are outside the U.S.) to challenge the IRS in Tax Court before the tax is assessed. The date is on the letter and it cannot be extended. If you got an IRS letter →
