Yes. Maine treats bonuses as taxable wages and requires Maine income tax withholding on bonus and other supplemental wage payments. Maine uses a progressive income tax system, which means withholding may vary depending on income level, filing status, and payroll setup.
When a bonus is paid, Maine withholding may be handled differently depending on how the bonus is processed. If supplemental wages are paid separately from regular wages, Maine allows employers to use a flat supplemental withholding rate. You can use the calculator above, powered by Beyond, to estimate Maine withholding and take-home pay for bonus payments. The calculator uses a 2026 estimate based on Maine withholding guidance and current payroll assumptions.
How to Calculate Bonus Tax in Maine
Supplemental wages—including bonuses, commissions, overtime pay, back pay, and certain additional wage payments—are generally treated as wages for withholding purposes.
For Maine state withholding:
– Paid separately from regular wages: employers may apply a flat withholding rate of approximately 5.0% to the bonus amount
– Paid together with regular wages: withholding may be calculated on the total combined wages for the payroll period using Maine withholding tables or formulas
– Actual withholding may vary depending on payroll setup, employee elections, and Maine Form W-4ME details
For federal withholding:
– 22% applies to most supplemental wages
– 37% applies to supplemental wages above $1 million in a calendar year
Key Information on Maine Bonuses
How Are Bonuses Paid in Maine?
Employers may issue bonuses through:
– Check
– Direct deposit
– Pay card
How Do Bonuses Work?
Bonuses are treated as taxable compensation. They are generally subject to:
– Federal income tax withholding
– Maine income tax withholding
– Social Security tax
– Medicare tax
They are typically reported on the employee’s Form W-2 at year-end.
What Is the Maine Bonus Tax Rate?
Maine does not rely on a single flat tax rate in all situations. However, when bonuses are paid separately from regular wages, employers commonly use a flat 5.0% supplemental withholding rate.
If bonuses are combined with regular wages, Maine withholding is calculated using standard withholding tables or formulas, which may result in different effective rates based on income.
Are Bonuses Taxed Differently Than Standard Pay?
At the Maine level, bonuses are treated as taxable wages, but withholding may be calculated differently depending on whether the bonus is processed separately or combined with regular wages.
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 Maine, estimated withholding may include:
– Maine income tax withholding (often ~5.0% when paid separately under the supplemental method)
– 22% federal supplemental withholding in most cases
– FICA taxes, including Social Security and Medicare
Because Maine withholding depends on income level, payroll setup, and employee elections, the exact amount taken from a bonus may vary from one employee to another.
