An estimate for planning purposes, not tax advice or a filing. Uses 2026 federal brackets (Rev. Proc. 2025-32), self-employment tax with the §199A (QBI) deduction, and state-level rates (Tax Foundation, 2026). Married-filing-separately filers should use "Single" as the closest estimate. Local income taxes (e.g. NYC, Ohio municipal) aren't modeled and would owe more than shown.

Frequently asked questions
How much should I set aside for taxes as a freelancer in Massachusetts?
For a single filer with $75,000 of 2026 self-employment income and no deductions, about 26% — roughly $1,625 a month. That covers $10,597 of self-employment tax, $4,898 of federal income tax and $3,750 of Massachusetts income tax. Your rate moves with your income, filing status and deductions, so use the calculator for your own numbers.
Does Massachusetts have a state income tax?
Yes. Massachusetts's 2026 individual income tax is progressive, 5%–9% across 2 brackets. Self-employment profit is taxed as ordinary income under that schedule.
What is the self-employment tax rate in Massachusetts?
Self-employment tax is federal, so it's the same in Massachusetts as everywhere else: 15.3% (12.4% Social Security on earnings up to the 2026 wage base of $184,500, plus 2.9% Medicare) applied to 92.35% of your net profit. An extra 0.9% Medicare tax applies above $200,000 for single filers. You can deduct half of it when figuring federal income tax.
When are quarterly estimated taxes due?
The next federal estimated payment is due January 15, 2027, covering income from Sep 1 – Dec 31, 2026. The 2027 payments are due April 15, 2027, June 15, 2027, September 15, 2027.
Do I also make estimated payments to Massachusetts?
Usually, yes — if you'll owe Massachusetts income tax that isn't covered by withholding, the state generally expects quarterly estimated payments too. Most states follow the federal due dates, but thresholds and schedules vary, so confirm with Massachusetts's revenue department.
