After Tax Deductions

After-tax deductions are amounts withheld from an employee’s paycheck after all mandatory taxes have been subtracted. These include deductions such as Roth 401(k) contributions, union dues, or wage garnishments.

How do after-tax deductions differ from pre-tax deductions?

Pre-tax deductions are taken from an employee’s paycheck before taxes, lowering their taxable income. Common examples include health insurance premiums and retirement contributions. After-tax deductions are taken from an employee's paycheck after mandatory taxes have been calculated, such as the Federal Insurance Contributions Act (FICA tax) and income tax.

What types of expenses are covered under after-tax deductions?

Types of after-tax deductions can include Roth 401(k) contributions, union dues, charitable donations, certain life insurance premiums, and wage garnishments. They may also include disability insurance premiums and post-tax commuter benefits.

How do after-tax deductions impact an employee’s net pay?

After-tax deductions reduce an employee’s earnings after income and payroll taxes are applied. The remaining amount, known as net pay or take-home pay, reflects the total earnings minus all pre-tax and after-tax deductions.
