Deductions: Post-Tax (After-Tax) Definition
Deductions from gross payroll wages after taxes have been withheld.
Post-tax deductions, also known as after-tax deductions, have no impact on taxable wages. Examples include loan repayments, employee purchases, Roth 401 (k) deductions, standard (not SIMPLE) IRA deductions, life insurance or charitable donations. Employers are not legally required to offer voluntary deductions.
