🎁 The 401(k) Balancing Act: Handling Retirement Benefits in Payroll

For a small business, offering a 401(k) or other qualified retirement plan is a powerful retention tool, but it adds a layer of complexity to your payroll. The key is proper classification of the employee's contribution.

Most employee 401(k) contributions are made on a pre-tax basis. This means the deduction is taken from the gross wages before federal income tax is calculated and withheld.

- The employee's taxable income is lowered, reducing their current federal income tax liability.

- Roth 401(k) contributions are made on an after-tax basis. The deduction is taken from the wages after federal income tax is calculated and withheld.

- The employee pays current income tax, but the money grows tax-free and is withdrawn tax-free in retirement.

Critically, both pre-tax and Roth contributions are still subject to Social Security, Medicare (FICA), and Florida Reemployment Tax (SUTA). You must deduct FICA and calculate SUTA on the full gross wage before the 401(k) contribution is taken out. Working closely with your payroll provider and 401(k) administrator is essential to avoid mistakes on W-2s and tax filings.
