1099 Tax Calculator for Connecticut — 2026

By Taxorly · Reviewed October 8, 2026 · How we calculate

Connecticut's top marginal rate is 6.99%, 12th of 51 states, and applies only to income in the top bracket. On $75,000 of 1099 income that is $3,084 to Connecticut on top of federal self-employment and income tax — about 17% of your total $18,579 bill, leaving $56,421. Neighbouring Rhode Island (top rate 5.99%) would take $890 less a year at this income.

Work in New York City? Freelancers who do their work in the city owe the NYC Unincorporated Business Tax on that share of their business income, wherever they live. It is not included here. For a non-resident it comes with New York State nonresident income tax and a credit on your Connecticut return, which this calculator does not model. Check with a tax professional.

About these Connecticut figures: state tax here is calculated from a compiled 2025/2026 rate table using each jurisdiction's brackets and standard deduction — not from Connecticut's own published schedule, and not every entry has been confirmed against it. Treat the result as an estimate and check anything you are relying on with Connecticut's revenue department. Federal figures come from published IRS releases and are cited on the pages that use them.

What Is a 1099 Tax in Connecticut?

No employer withholds tax from a 1099-NEC, so a Connecticut contractor settles the whole bill themselves. Worked through on $75,000 of net freelance income, the three pieces come out like this:

Self-employment tax — $10,597: 15.3% covering Social Security and Medicare, charged on 92.35% of net earnings. Federal, so it is the same in Connecticut as anywhere else.
Federal income tax — $4,898: what remains after deducting half your self-employment tax and the $16,100 standard deduction, then running the 2026 brackets.
Connecticut income tax — $3,084: 4.11% of your gross income once Connecticut's brackets and deductions are applied, which is 17% of everything you owe and ranks Connecticut 12 of 51 nationally.

That totals $18,579, an effective rate of 24.8%, leaving $56,421 once Connecticut has taken its share.
