Does Connecticut Tax Overtime Pay? (2026)
Yes — at the state level, Connecticut taxes overtime exactly like regular wages. But the new federal overtime deduction (2025–2028) changes the overall math significantly. Here's the full picture.
The three layers of tax on Connecticut overtime
- Federal income tax: overtime is taxable — but for 2026, the premium ("half") portion of FLSA time-and-a-half is deductible up to $12,500 (single) / $25,000 (joint). Estimate yours with the overtime deduction calculator.
- Payroll taxes: Social Security (6.2%) and Medicare (1.45%) always apply to overtime — no exceptions.
- Connecticut state tax: overtime is added to your regular wages and taxed under the normal graduated brackets — about 5.5% for a typical full-time earner. Connecticut has not adopted the federal overtime deduction (connecticut uses personal exemptions and credits rather than a standard deduction; low earners owe much less than the raw brackets suggest).
What $5,000 of overtime actually costs in tax
Say you earn $5,000 of overtime (time-and-a-half) in Connecticut as a typical single filer:
- Payroll taxes take 7.65% ≈ $383.
- Connecticut state tax ≈ $275 (at 5.5%).
- Federal income tax applies to the full $5,000 through withholding — but at filing, the ~$1,667 premium portion is deductible, worth roughly $200–$400 back depending on your bracket.
Bottom line: working overtime in Connecticut is more rewarding in 2026 than the raw withholding suggests — most workers see the federal benefit as a larger refund.

Frequently asked questions
Did Connecticut adopt the federal "no tax on overtime" rule?
No. The overtime deduction is federal-only, and Connecticut continues to tax overtime as ordinary wages. A few states have debated their own exemptions — check the state DOR for current-year changes.
Is overtime withheld at a higher rate?
It can look that way on a single paycheck — a big OT check pushes that period's withholding into a higher bracket temporarily. At filing, everything settles to your actual annual rate, so the 'overtime is taxed more' feeling is a withholding illusion, not a real higher tax.
Does the federal overtime deduction lower my state taxable income?
Generally no — most states, including Connecticut, calculate state tax without the new federal deduction. It reduces federal taxable income only.
