How Massachusetts taxes 1099 income

If you’re a freelancer, independent contractor, gig worker, or solo business owner in Massachusetts, your net profit (1099 income minus business expenses) is taxed three ways:

  1. Federal self-employment tax: 15.3% on most of your profit (92.35% of it). That’s 12.4% for Social Security, on earnings up to $184,500 in 2026, plus 2.9% for Medicare with no cap. It replaces the payroll taxes an employer would split with you. Estimate it with the self-employment tax calculator.
  2. Federal income tax: 10% to 37% on what’s left after three deductions: the $16,100 standard deduction ($32,200 married filing jointly), half of your self-employment tax, and the 20% QBI deduction.
  3. Massachusetts income tax: a flat 5% on your profit minus up to $2,000 of self-employment tax and a $4,400 personal exemption ($8,800 married filing jointly). You report it on Form 1.

What’s different about Massachusetts

  • Its own deduction for self-employment tax. The IRS lets you subtract half of your self-employment tax. Massachusetts doesn’t; instead, it lets you deduct the Social Security and Medicare tax you pay, including self-employment tax, up to $2,000 per person. At $80,000 of profit, that’s $2,000 instead of the IRS’s $5,652.
  • No standard deduction. You subtract a $4,400 personal exemption ($8,800 married filing jointly, $6,800 head of household), plus $1,000 for each dependent.
  • No QBI deduction. The IRS lets you deduct up to 20% of your business profit. Massachusetts doesn’t. At $80,000 of profit, that’s $11,650 you deduct on your federal return but still pay Massachusetts tax on.
  • A 4% surtax on very high incomes. Taxable income over $1,107,750 in 2026 is taxed at 9% instead of 5%.
  • You need health insurance. Massachusetts requires residents to have qualifying coverage or pay a penalty on their state return, and you report your coverage on Schedule HC.

Because Massachusetts taxes nearly your whole profit at 5%, a self-employed person at $80,000 pays $20,327: about $1,067 more than in California and $3,680 more than in Texas, which has no income tax.

Example: Massachusetts tax on $80,000 of 1099 income

Here’s the math for a single self-employed person in Boston with $80,000 of profit and no other income.

StepAmount
Self-employment tax: $80,000 × 92.35% × 15.3%$11,304
$80,000 minus half of self-employment tax$74,348
Income the IRS taxes: $74,348 minus the $16,100 standard deduction and $11,650 QBI deduction$46,599
Federal income tax$5,344
Income Massachusetts taxes: $80,000 minus $2,000 of self-employment tax and the $4,400 exemption$73,600
Massachusetts income tax: 5%$3,680
Total 2026 tax$20,327 (25.4%)

Self-employment tax is the biggest piece. Every dollar you write off as a business expense lowers all three taxes, since your self-employment tax, federal income tax, and Massachusetts income tax are all based on your profit after expenses.

How to lower your Massachusetts 1099 tax bill

At $80,000 of profit, every $1,000 of business expenses you deduct cuts about $281 from your total tax. Common write-offs for self-employed people in Massachusetts include:

Most of these are small purchases spread across a year of bank and card statements, which is where they get missed. See the full list of tax write-offs for self-employed people.

Massachusetts estimated tax payments

If you expect to owe more than $400 in Massachusetts tax for 2026 on income with no tax taken out, make estimated payments to the Massachusetts Department of Revenue through MassTaxConnect or with Form 1-ES. They’re due on the same dates as your federal payments, and each is a quarter of your Massachusetts tax:

PaymentShare of your Massachusetts taxDue date
1st25%April 15, 2026
2nd25%June 15, 2026
3rd25%September 15, 2026
4th25%January 15, 2027
  • Federal payments are separate: you pay the IRS on the same four dates with Form 1040-ES.
  • To avoid a penalty for paying too little, pay at least 80% of this year’s Massachusetts tax, or 100% of last year’s if you filed a full-year Massachusetts return. That’s a lower bar than the IRS’s 90%.

Get your payment amounts with the Massachusetts quarterly tax calculator.

Should you form an LLC or S corp in Massachusetts?

You don’t need one to work as an independent contractor. If you work for yourself without forming a business, you report 1099 income on Schedule C, part of your regular tax return, and pay the taxes above. Massachusetts is one of the most expensive states to have one:

  • LLCs cost $500 to form and $500 a year for the annual report.
  • S corps can make sense once your profit is around $80,000, when the self-employment tax savings get significant. You pay yourself a reasonable salary and take the rest as profit payouts (distributions) that aren’t subject to self-employment tax. Massachusetts S corps pay a corporate excise of at least $456 a year.

Run the numbers for your income to see what you’d save.

Do self-employed people in Massachusetts charge sales tax?

Usually not. Most professional services, like writing, design, consulting, and bookkeeping, aren’t taxable in Massachusetts. Physical goods and prewritten software are, at 6.25%.
