Tax moves that matter most for Maine
If you own an S corporation, partnership or multi-member LLC, Maine's PTET election moves the Maine income tax on that profit to the business, where it is deductible federally and outside the SALT cap.
An S-corp election can cut self-employment tax once profit is large enough to pay yourself a reasonable salary and still cover payroll and filing costs. The Maine calculator adds Maine's own entity fees and taxes to that breakeven.
With 1099 income, a Solo 401(k) can take up to $72,000 a year (2026) — usually more than a SEP-IRA at the same income. Contributions lower both federal and Maine income tax.
