Types of Performance-Based Supplemental Pay
- Annual performance review bonus: fixed or discretionary amount based on review rating
- Management by Objectives (MBO) payout: achievement-based percentage of salary
- Spot bonus: one-time recognition for a specific project or achievement
- Team-based performance bonus: split among a group based on collective results
- Deferred performance bonus: earned now, paid in a future year (NQDC-style)
- Equity performance units: performance shares or RSUs tied to metrics — different tax rules apply
How the Withholding Method Affects Performance Bonuses
Most performance bonuses are paid as separate checks and subject to the flat 22% federal withholding rate. Annual review bonuses, particularly large ones paid once per year, benefit from the flat method because they are naturally issued separately from regular salary. Spot bonuses added to a regular paycheck trigger the aggregate method.
Performance bonus types and typical withholding method
| Performance Bonus Type | Typically Paid | Method Used | Expected Federal Withholding |
|---|---|---|---|
| Annual review bonus | Separate check | Flat 22% | 22% predictable |
| MBO quarterly payout | Separate supplemental check | Flat 22% | 22% predictable |
| Spot bonus added to paycheck | Combined with regular pay | Aggregate method | Higher — varies by salary |
| Deferred compensation payout | Future year, separate payment | Flat 22% or aggregate | Depends on payment structure |
If your company is adding a spot bonus to your regular paycheck, request that it be issued as a separate payment. This qualifies it for the flat 22% federal rate rather than the aggregate method — potentially reducing withholding by thousands of dollars on larger awards.
Planning Around Annual Review Bonuses
Annual review bonuses typically arrive in Q1 of the following year (January-March), covering performance from the prior year. This means the bonus income falls in the new year — when your annual income starts at zero, and the 22% flat withholding may be much higher than your actual marginal rate on just that bonus amount. For employees in the 12% bracket, a January review bonus triggers 22% withholding, creating a reliable refund situation.
