Is There a Federal Rule for Final Paychecks?
It may come as a surprise, but the federal government does not establish a specific deadline for when final paychecks must be issued. In practice, final paycheck timing is generally governed by state law, which is why employers should review the rules that apply in the state where the employee worked.
Connecticut Final Paycheck Rule
Connecticut does have specific final paycheck timing rules. If an employee is discharged, final wages are generally due no later than the next business day. If an employee leaves voluntarily or is laid off, final wages are generally due by the next regular payday.
Because timing matters, employers should make every effort to pay all wages owed promptly and consistently under their normal payroll process.
Important Final Paycheck Considerations
Even when an employee is terminated, employers cannot withhold wages that have already been earned. A final paycheck should include all compensation due through the employee’s last day worked. Connecticut guidance also states that employers generally cannot withhold or divert wages unless permitted by law or authorized in writing in a manner allowed by statute.
Employers should also review whether the employee is entitled to payment for accrued or unused vacation or PTO. Connecticut does not have a broad statewide rule that requires PTO or vacation payout in every situation, so payout often depends on the employer’s handbook, contract, or established policy.
If severance is being paid, it is generally treated as taxable wages for withholding purposes. Employers should also remember that Connecticut state income tax withholding may still apply to taxable final wages when appropriate. Connecticut’s 2025–2026 withholding materials include the 2026 Form CT-W4 and 2026 withholding guidance, so employers should make sure their payroll setup reflects the current year’s forms and rules.
Because final paycheck rules and payroll tax requirements can vary depending on the situation, employers should confirm the rules that apply to their business and workforce before processing a final check.
