Key takeaways
- Due to their nature as additional income, supplemental wages are subject to specific tax rates, both at the federal and state level.
- While the federal supplemental tax rate is a flat 22%, states have different approaches, with some imposing specific rates, others applying regular income tax rates, and some having no provisions for supplemental wages at all.
- Given the varying state regulations, ensuring accurate tax withholdings and payments can be challenging for employers. Using a payroll management solution like Deel US Payroll can help streamline this process.
Supplemental pay, also known as supplemental wages, is additional income an employee receives on top of their regular monthly wages or salary.
Since supplemental wages differ from regular wages in regard to payment dynamics, the tax rate applied also differs. The federal supplemental tax rate is a flat 22%, but states may have their own rates or provisions.
