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 the box below. 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.
