DC Bonus Tax Calculator:
Employers' Trusted Tool for Accurate Bonus Payments
The Washington, DC bonus tax calculator available on this page helps employers and employees estimate the correct withholding and net (take-home) pay for supplemental wage payments such as bonuses or commissions.
Does Washington, DC Tax Bonuses?
Yes. The District of Columbia treats bonuses as taxable wages subject to both federal and DC income tax withholding. Unlike some states that apply a flat supplemental rate, DC uses its standard progressive income tax brackets to determine withholding on bonuses.
If the bonus is paid together with regular wages, the combined total is taxed as ordinary income using the DC withholding tables.
If the bonus is paid separately, employers typically calculate withholding based on the employee’s marginal DC tax rate, which can range from 4% to 10.75% depending on total annual income.
How to Calculate Bonus Tax in Washington, DC
For separately paid bonuses, employers can approximate withholding by applying the employee’s marginal DC rate to the bonus amount.
If the bonus is paid in the same check as regular wages, DC requires withholding using the aggregate method—that is, combining the bonus and regular wages to calculate the total tax from the tables.
What Is the Bonus Tax Rate in Washington, DC?
DC does not have a flat bonus tax rate.
Instead, employees are subject to the same graduated income tax brackets used for all wages:
– 4% on the first $10,000 of taxable income
– 6% on income between $10,001 and $40,000
– 6.5% on income between $40,001 and $60,000
– 8.5% on income between $60,001 and $250,000
– 9.25% on income between $250,001 and $500,000
– 9.75% on income between $500,001 and $1,000,000
– 10.75% on income above $1,000,000
When a bonus pushes an employee into a higher bracket, the portion of income above the threshold is taxed at the higher rate.
How Do Bonuses Work in Washington, DC?
Employers can pay bonuses either as a lump-sum payment or include them with a regular paycheck.
If the payment is made separately, the employer must withhold federal taxes at 22% (or 37% above $1M YTD) and apply the employee’s estimated DC marginal rate as shown above.
All bonus payments must be properly reported on the employee’s Form W-2.
Why Are Bonuses Taxed Differently from Regular Pay?
The federal and DC tax systems treat bonuses as supplemental wages.
Federal law applies a flat 22% rate to simplify withholding on separate bonus payments, while DC taxes the same income using its progressive brackets.
This approach ensures accurate withholding and avoids underpayment when income varies throughout the year.
How Can Washington, DC Employers Pay Bonuses?
Bonuses can be paid through any of the following methods:
– Check
– Direct deposit
– Pay card or electronic pay system
Employers should also ensure that Social Security and Medicare (FICA) taxes are withheld on the bonus, as these apply in addition to federal and DC income tax.
How Much Tax Is Taken Out of a Bonus in Washington, DC?
Total withholding—excluding FICA contributions—will generally equal 22% federal plus the employee’s DC marginal rate (typically between 4% and 10.75%).
For example, a DC resident in the 8.5% bracket would see approximately 30.5% total withholding (22% + 8.5%) before Social Security and Medicare.
