Severance pay in Connecticut
In Connecticut, the first decisions after a layoff are not just about the size of your severance check. You need to distinguish payroll withholding from your eventual federal tax bill, file unemployment promptly because CTDOL generally will not pay weeks before your first claim, and check whether severance, salary continuation, vacation pay, or partial work affects particular benefit weeks.

What severance means in Connecticut
Connecticut generally treats severance as wages for state withholding when it is subject to federal withholding. That does not mean Connecticut takes one flat rate from the check: the withholding system uses your CT-W4 code, annualized wages, exemptions, and payroll method. Your final Connecticut tax depends on filing status, deductions, credits, residency, payment timing, and total annual taxable income.
Federal separately identified supplemental wages commonly use 22% withholding in 2026, while severance is also subject to Social Security and Medicare taxes. A lump-sum check can therefore look heavily reduced even when your final tax liability is lower or higher after the full-year return. Ask payroll whether the payment is a lump sum, salary continuation, wages in lieu of notice, or accrued PTO, because those labels can affect unemployment treatment.
A worked example
- Salary $72,000 annually
- Years employed 4
- Severance 8 weeks
- Lump-sum payment
- Connecticut withholding calculated as $0 for illustration only because the example assumes no CT withholding is elected; actual CT withholding may apply
- Federal supplemental withholding 22%
- Employee FICA 7.65%
- Single filer; no dependents, credits, deductions, prior withholding, wage-base complications, or Additional Medicare Tax included
Illustrative payroll-withholding estimate - not final tax advice. The gross amount is $72,000 ÷ 52 × 8; actual payroll withholding and final tax can differ materially.
Run your own numbers →Unemployment in Connecticut
01A laid-off Connecticut worker generally must be able and available for work, totally or partially unemployed, have qualifying Connecticut work and wages, and meet CTDOL filing and job-search rules. The standard calculation is ((highest-quarter wages + second-highest-quarter wages) ÷ 2) ÷ 26, subject to the applicable minimum and the $721 weekly maximum; eligible dependents may add $15 per week each under CTDOL rules.
02File immediately through CTDOL even if paperwork is incomplete. Your benefit year starts on the Sunday of the week you file. Severance or salary continuation may disqualify you for weeks covered by the payment; accrued vacation paid at dismissal may be treated differently, while vacation pay during a shutdown can reduce or eliminate benefits. Report all work and gross earnings when earned, and expect CTDOL to decide disputed payment treatment.
Your first 72 hours
- 01The wording and covered dates can determine whether a payment is severance, salary continuation, wages in lieu of notice, or PTO for unemployment purposes.
- 02CTDOL generally will not pay weeks before your first claim unless a hearing later determines that backdating is justified.
- 03Connecticut benefit weeks run Sunday through Saturday, and late weekly filing can interrupt payment.
- 04Connecticut requires three weekly activities and records should be kept for three years.
- 05Federal COBRA generally gives at least 60 days to elect after the later of coverage loss or the election notice; Marketplace special enrollment may also apply.
- 06The federal 22% supplemental rate and FICA deductions are payroll rules, not a personalized final-tax calculation; Connecticut withholding depends on the payroll calculation and your CT-W4.
The Connecticut calculator estimates gross severance, common federal supplemental withholding, employee FICA, and an optional Connecticut withholding assumption from the inputs you provide. It uses Connecticut-specific unemployment maximum and formula references only where verified, and every result is an educational estimate rather than final tax, payroll, or CTDOL advice.
Connecticut severance FAQ
Does Connecticut take a flat tax percentage from my severance check?
No. Connecticut has graduated income-tax rates, and its withholding calculation uses annualized wages and your CT-W4 information. A payroll withholding amount is not the same as your final tax liability.
Should I wait until my severance ends before filing unemployment?
Usually file promptly rather than assuming. CTDOL says severance or salary continuation can make you ineligible during covered weeks, but filing timing affects the claim start and CTDOL should decide the weeks affected.
Will accrued vacation paid when I leave block Connecticut unemployment?
Not automatically. CTDOL guidance says accrued vacation paid at dismissal may not disqualify an otherwise eligible claimant, while vacation pay during a shutdown can reduce or disqualify benefits. Report it and follow CTDOL's determination.
What happens if I work part-time while claiming Connecticut unemployment?
Report gross earnings when earned. CTDOL says weekly benefits can be reduced by two-thirds of weekly gross earnings, and you generally must continue seeking full-time work unless an approved exemption applies.
How many job-search activities must I complete in Connecticut?
At least three each week, including at least one direct employer contact. Report them with the weekly claim and keep supporting records for three years.
When does my Connecticut unemployment benefit year begin?
It begins on the Sunday of the calendar week in which you file your claim, and the claim generally remains valid for 52 weeks. Benefits are normally payable for up to 26 weeks within that benefit year.
