Maine LLC Taxes Explained: 5.8–7.15%, No Entity Tax (2026)
Maine default LLC income generally passes to owners under its graduated income-tax schedule. The 2026 elective PTE tax and separate high-income surcharge require additional analysis. The illustration below does not calculate a complete return.
Default LLC income generally passes through to owners; corporate classification and eligible elections change the analysis. For taxable years beginning January 1,2026 or later, eligible pass-through entities may elect Maine entity-level tax. The tax is 7.15% of covered PTE taxable income, excluding the separate individual high-income surcharge. Qualified members may claim a refundable credit equal to 90% of their share of PTE tax paid. Separate nonresident estimated-payment and reporting rules can apply. This is distinct from default owner-level taxation and from the SOS annual report. For 2026, the separate 2% surcharge applies to Maine taxable income above $1,000,000 single,$750,000 married filing separately, or $1,500,000 joint/head of household. It is additional to the 5.8%/6.75%/7.15% marginal base-rate schedule.

The 4 Layers of Maine LLC Taxation
Federal: income + self-employment tax
Pass-through profits hit your 1040 at your federal bracket, plus 15.3% SE tax on 92.35% of net profit — usually the biggest line.
Maine income tax: graduated 5.8–7.15%
Three brackets — 5.8%, 6.75%, and a 7.15% top rate — applied to Maine taxable income. Unlike the flat-tax states earlier in this series, your effective rate climbs with profit.
Entity level: review classification and PTE election
For taxable years beginning January 1,2026 or later, eligible pass-through entities may elect Maine entity-level tax. The tax is 7.15% of covered PTE taxable income, excluding the separate individual high-income surcharge. Qualified members may claim a refundable credit equal to 90% of their share of PTE tax paid. Separate nonresident estimated-payment and reporting rules can apply. This is distinct from default owner-level taxation and from the SOS annual report.
Sales & use tax: 5.5% (if applicable)
Effective January 1,2026, Maine’s Service Provider Tax is repealed. Review current sales/use tax treatment of each previously covered service; repeal does not mean every service is exempt. The ordinary sales/use rate is 5.5%, with special rates including 8% prepared food and 9% lodging. Remote sellers and nonresident marketplace facilitators review the more-than-$100,000 current/prior-year gross-sales threshold. A seller with no Maine physical presence selling only through marketplaces need not register if the facilitator provides the required written collection statement. Direct sales require a separate threshold analysis; facilitator-collected marketplace sales do not count toward that seller’s direct-sales threshold. Maine physical presence changes registration duties.

Assumes no other wages, caps 2026 Social Security at $184,500, and subtracts half the illustrated SE tax before the assumed Maine base-rate calculation. Omits Maine deductions/exemptions and their phaseouts, federal income tax, QBI, credits, additional Medicare tax, PTE election and the high-income surcharge. Use current tax-year instructions for an actual return.
2026 high-income surcharge: Maine adds a 2% surcharge to the portion of Maine taxable income above the statutory high-income thresholds ($1,000,000 single, $750,000 married filing separately, or $1,500,000 married filing jointly/head of household for 2026). This is separate from the regular 5.8% / 6.75% / 7.15% brackets.
How Maine's Brackets Actually Work
| Rate | Applies To (single, approx. 2026) | MFJ (approx.) |
|---|---|---|
| 5.8% | First ~$26,800 of taxable income | First ~$53,600 |
| 6.75% | ~$26,800 – ~$63,450 | ~$53,600 – ~$126,900 |
| 7.15% | Above ~$63,450 | Above ~$126,900 |
Marginal, not flat: crossing a threshold taxes only the dollars above it at the higher rate. Thresholds are inflation-indexed each year — confirm current figures with Maine Revenue Services at filing time. Practical effect: a modest-profit LLC pays an effective state rate well under the 7.15% headline, while six-figure earners converge toward it.
The S-Corp Question
An S-corporation election requires actual reasonable wages, payroll costs, compliance and owner circumstances. Distributions do not automatically escape Maine owner-level income tax. Consider Maine classification, the elective PTE tax and nonresident obligations separately; no universal profit threshold establishes savings.

Ahmad Adil's Take: Maine does not impose a separate franchise tax on a default pass-through LLC, but owner-level income tax can reach 7.15% before the separate 2026 high-income surcharge applies. That makes tax planning worth modeling carefully. An S-Corp election is not triggered by one magic profit number: compare reasonable salary, profit consistency, payroll and accounting costs, retirement-plan options, and your own tax situation with a qualified tax professional.
