Step 2(b)—Multiple Jobs Worksheet (Keep for your records
If you choose the option in Step 2(b) on Form W-4, complete this worksheet (which calculates the total extra tax for all jobs) on only ONE Form W-4. Withholding will be most accurate if you complete the worksheet and enter the result on the Form W-4 for the highest paying job.
Note: If more than one job has annual wages of more than $120,000 or there are more than three jobs, see Pub. 505 for additional tables; or, you can use the online withholding estimator at www.irs.gov/W4App.
