Which method does your employer use? Most employers use the flat 22% federal supplemental withholding rate — it's simpler to administer. The aggregate method applies if your employer combines your bonus with a regular paycheck. Either way, your actual tax liability is the same when you file your return — only the withholding differs.
Frequently Asked Questions
Does my state tax my bonus the same as regular income?
Most states treat bonus income as ordinary income subject to the same rates as your regular salary. A handful of states mirror the federal supplemental withholding rate for administrative convenience, but all states reconcile your actual tax liability when you file your return. The calculator above applies your state's income tax rate to the bonus amount directly.
What is the difference between flat and aggregate method for state taxes?
Most states default to the aggregate method — they combine the bonus with your regular pay and withhold at the combined rate. A few states have their own supplemental withholding rate. Either way, the actual tax owed is determined at filing based on your total annual income. This calculator uses the differential (aggregate) approach to estimate state tax on your bonus.
