TIP: Consider using the estimator at www.irs.gov/W4App to determine the most accurate withholding for the rest of the year if: you are completing this form after the beginning of the year; expect to work only part of the year; or have changes during the year in your marital status, number of jobs for you (and/or your spouse if married filing jointly), dependents, other income (not from jobs), deductions, or credits. Have your most recent pay stub(s) from this year available when using the estimator. At the beginning of next year, use the estimator again to recheck your withholding. Complete Steps 2–4 ONLY if they apply to you; otherwise, skip to Step 5. See page 2 for more information on each step, who can claim exemption from withholding, and when to use the estimator at www.irs.gov/W4App.
