For freelance designers, developers, writers and other 1099 professionals in Connecticut. Connecticut has a graduated state income tax for 2026: 2% to 6.99% (top rate starts at $500,000 for single filers). Here are the 2026 rules, a worked example and the official sources.
Connecticut rules for freelancers
- State income tax (2026)
- Connecticut has a graduated state income tax for 2026: 2% to 6.99% (top rate starts at $500,000 for single filers). Rates are percentages. 2026 single brackets: 2% on the first $10,000 of Connecticut taxable income, then 4.5%, 5.5%, 6%, 6.5% and 6.9%, with 6.99% on income over $500,000 (DRS IP 2026(7), 2026 tax calculation schedule). Higher earners also lose the benefit of the 2% bracket through a phase-out add-back.
- State estimated tax
- You must pay estimated tax if your Connecticut income tax after withholding and any pass-through entity tax credit will be $1,000 or more and your withholding will be less than your required annual payment. Same dates as federal: 25% each on April 15, June 15 and September 15, 2026 and January 15, 2027. Farmers and fishermen make one payment by January 15, 2027. Form CT-1040ES.
- ABC test for unemployment insurance
- For unemployment insurance, the Connecticut Department of Labor treats a worker as an employee unless all three are true: the worker is free from direction and control, the work is outside the usual course of the business or outside all its places of business, and the worker is customarily engaged in an independently established trade or business. The Department of Revenue Services uses common-law control rules for tax purposes instead.
- State retirement program

Federal rules for 2026
Self-employment tax
On top of income tax, self-employed people pay 15.3% on 92.35% of net profit: 12.4% Social Security up to the 2026 wage base of $184,500, plus 2.9% Medicare with no cap. Half of it is deductible.
All income counts, form or no form
Clients and marketplaces send 1099-NEC or 1099-K forms only above IRS reporting thresholds, but every dollar of freelance income is taxable whether or not a form arrives.
Home office and tools
If you use part of your home regularly and only for work, the simplified home-office deduction is $5 per square foot up to 300 square feet. Software, equipment and a business share of your phone and internet are deductible too.
Quarterly estimated taxes
No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.
A worked example
| Self-employment tax | $12,010 |
|---|---|
| Self-employment tax per quarter | $3,003 |
| Solo 401(k) maximum | $40,299 |
| SEP IRA maximum | $15,799 |
Federal figures only. Income tax comes on top; the quarterly tax calculator estimates both. Computed from 2026 IRS limits (Notice 2025-67, Rev. Proc. 2025-32) and the SSA wage base.
