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 earned from all of these jobs.
Do only one of the following.
- (a) Use the estimator at www.irs.gov/W4App for most accurate withholding for this step (and Steps 3–4); or
- (b) Use the Multiple Jobs Worksheet on page 3 and enter the result in Step 4(c) below for roughly accurate withholding; or
- (c) If there are only two jobs total, you may check this box. Do the same on Form W-4 for the other job. This option
is accurate for jobs with similar pay; otherwise, more tax than necessary may be withheld.
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.
