How this calculator works

  1. Net profit is your gross 1099 income minus deductible business expenses.
  2. Self-employment tax is 15.3% (12.4% Social Security up to the $184,500 wage base, plus 2.9% Medicare) on 92.35% of net profit.
  3. Federal income tax applies the 2026 brackets after subtracting half of your SE tax, the standard deduction and the 20% qualified business income (QBI) deduction.
  4. Massachusetts tax applies Massachusetts's brackets to your adjusted gross income after the state deduction or exemption.
  5. Quarterly payments divide the annual federal amount evenly.

Not included: credits, itemized deductions, retirement contributions (SEP-IRA, Solo 401(k)), self-employed health insurance deduction and local taxes. Each of these usually lowers the bill, so treat the result as a conservative upper estimate.

Frequently asked questions

How much should I set aside for 1099 taxes in Massachusetts?

A Massachusetts freelancer filing single with $100,000 of net profit owes roughly $26,791 in combined self-employment, federal and state income tax for 2026, an effective rate of about 26.8%. A practical rule of thumb is to move 30% of every client payment into a separate tax savings account, then fine-tune once you know your real deductible expenses.

What is the Massachusetts income tax rate for self-employed people?

Massachusetts has a progressive income tax from 5% to 9%. Self-employed people pay the same state rates as employees on their net business income; there is no separate state self-employment tax. On $100,000 of net profit, the Massachusetts portion comes to about $4,427.

When are Massachusetts quarterly estimated tax payments due?

Federal estimated payments for the 2026 tax year are due April 15, 2026, June 15, 2026, September 15, 2026 and January 15, 2027. Massachusetts estimated payments are made with Form 1-ES to the Massachusetts Department of Revenue and generally follow the same calendar.

Do Massachusetts freelancers pay self-employment tax on top of income tax?

Yes. Self-employment tax (15.3% for Social Security and Medicare, applied to 92.35% of net earnings) is a federal tax, so every 1099 earner pays it regardless of state. On $100,000 of net profit it is about $14,130. Half of it is deductible when calculating federal income tax, and the Social Security portion stops at the $184,500 wage base.

Does the Massachusetts millionaires' tax affect married couples differently?

Yes. The surtax threshold is the same for single filers and married couples filing jointly, so a two-earner household reaches it at the same combined income as one individual. Some high-income couples compare joint and separate filing for this reason.
