Step 2: Multiple Jobs or Spouse Works
Complete this step if you (1) hold more than one job at a time, or (2) are married filing jointly and your spouse also works. The correct amount of withholding depends on income eraned from all these jobs.
Do only one of the following.
TIP: To be accurate, submit a 2021 Form W-4 for all other jobs. If you (or your spouse) have self-employment income, including as an independent contractor, use the estimator.
Complete steps 3-4(b) on Form W-4 for only ONE of thse jobs. Leave those steps blank for the other jobs. (Your withholding will be most accurate if you complete steps 3-4(b) on the FOrm 2-r for the highest paying job)
