Year-end bonus: how it is taxed and how to use it well

No 13th month, but often a bonus

Unlike many countries in Latin America and Europe, the U.S. has no law requiring a 13th-month salary. Year-end bonuses are up to each employer: some pay a fixed holiday bonus, others tie it to company or individual performance, and many pay nothing at all. If your offer letter or employee handbook promises a bonus, the rules there are what count.

Why your bonus looks so heavily taxed

For federal income tax, the IRS treats bonuses as supplemental wages. Employers often withhold a flat 22% federal rate on them (37% on the part above $1 million), plus Social Security, Medicare and any state income tax. That is why a $2,000 bonus can land in your account closer to $1,400 or $1,500.

Withholding is not your final tax. When you file your return, the bonus is added to your other income and taxed at your actual rates. If too much was withheld, you get the difference back as a refund; if too little, you owe it.

Ways to keep more of it

• Ask about deferring part to your 401(k), if your plan allows contributions from bonuses. It lowers your taxable income now.
• Use a health savings account, if you have one, for tax-advantaged medical savings.
• Check your W-4 if you regularly owe or get large refunds, so your total withholding matches your situation.

Decide where it goes before it arrives

Money that arrives with no plan tends to disappear in holiday shopping. A simple split works for many people: one part to expensive debt, like credit card balances; one part to your emergency fund; and one part to enjoy, guilt-free. Deciding the percentages before the bonus hits your account makes them much easier to stick to.
