Mississippi Bonus Tax Calculator:
Employers' Trusted Tool for Accurate Bonus Payments

The Mississippi bonus tax calculator available on this page helps employers quickly estimate the net pay, or take-home pay, an employee may receive from bonus payments.
Does Mississippi Tax Bonuses?
Yes. Mississippi treats bonuses as taxable wages and requires Mississippi income tax withholding on bonus and other supplemental wage payments. Mississippi has been transitioning toward a simplified income tax structure, and for 2026, taxable income above a certain threshold is generally subject to a flat rate.
When a bonus is paid, Mississippi withholding may be handled using the same general approach applied to regular wages. Unlike some states, Mississippi does not use a separate flat supplemental rate specifically for bonuses. You can use the calculator above, powered by Beyond HCM, to estimate Mississippi withholding and take-home pay for bonus payments. The calculator uses a 2026 estimate based on current Mississippi withholding guidance and payroll assumptions.
How to Calculate Bonus Tax in Mississippi
Supplemental wages—including bonuses, commissions, overtime pay, back pay, and certain additional wage payments—are generally treated as wages for withholding purposes.
For Mississippi withholding:
– Paid separately from regular wages: withholding is typically estimated using an effective statewide rate (approximately 4.0% in 2026 for income above the threshold)
– Paid together with regular wages: withholding may be calculated on the total combined wages for the payroll period using Mississippi withholding tables and the employee’s exemption information
– Actual withholding may vary depending on payroll setup, employee elections, and state withholding tables
For federal withholding:
– 22% applies to most supplemental wages
– 37% applies to supplemental wages above $1 million in a calendar year
Key Information on Mississippi Bonuses

What Is the Mississippi Bonus Tax Rate?
Mississippi does not apply a unique “bonus tax rate.” Instead, bonuses are subject to the same income tax structure as regular wages.
For 2026, Mississippi generally applies:
– 0% on the first portion of taxable income
– 4.0% on taxable income above the applicable threshold
Because of this structure, many payroll calculations use an estimated effective rate of approximately 4.0% for bonus withholding, especially in simplified calculators.
Are Bonuses Taxed Differently Than Standard Pay?
At the Mississippi level, bonuses are treated as taxable wages and are not subject to a separate supplemental tax rate. However, withholding may be calculated differently depending on how the bonus is processed and how the employer applies withholding tables.
At the federal level, bonuses may be taxed using the supplemental wage method, typically 22% when paid separately, subject to the higher $1 million rule.
How Much Tax Is Taken Out of a Bonus?
For most bonus payments in Mississippi, estimated withholding may include:
– Mississippi income tax withholding (commonly estimated around 4.0% for 2026)
– 22% federal supplemental withholding in most cases
– FICA taxes, including Social Security and Medicare
Because Mississippi withholding depends on exemption amounts, wage levels, and payroll setup, the exact amount taken from a bonus may vary from one employee to another.
