Unlike some countries with a legally mandated year-end bonus, the US has no statutory requirement for employers to pay a 13th-month or holiday bonus — any bonus you receive is generally discretionary, set by your employer's own policy, not a guaranteed legal entitlement.
The IRS treats bonuses as "supplemental wages," and employers commonly withhold a flat 22% for federal tax on bonuses up to $1 million (37% on any amount above $1 million) — separate from how your regular paycheck withholding is calculated. This flat withholding rate is not necessarily your actual tax rate — it's just what's withheld upfront; your real tax liability on that bonus is reconciled when you file your return, based on your actual marginal tax bracket for the year, which may be higher or lower than 22%.
Before deciding what to spend a bonus on, check two things: whether you're carrying high-interest debt (see the debt payoff guide on this site — paying that down usually beats any low-risk investment return) and whether your emergency fund is fully funded (see the emergency fund guide). A bonus is a natural opportunity to make meaningful progress on either in a single lump sum, rather than relying only on gradual monthly contributions.
If high-interest debt is under control and your emergency fund is complete, a bonus is a good opportunity to make a larger-than-usual contribution to a tax-advantaged retirement account — see the 401(k)/IRA guide on this site, especially if you haven't yet maxed out your annual contribution limit for the year.
