If you are referencing a Form W-4 for your dependent who will be an employee you can see IRS.gov/W4app for help beyond the instructions to complete the form.
To provide maximum accuracy, you are encouraged to use the Tax Withholding Estimator. You should consider using the withholding estimator if you:
- expect to work only part of the year (this does not apply if you are only switching jobs),
- had a large balance due or refund last year and it is no longer the beginning of the current year,
- have dividend or capital gain income or are subject to additional taxes, such as the additional Medicare tax,
- have self-employment income,
- prefer the most accurate withholding for multiple job situations, or
- prefer to limit information provided in Steps 2–4 but do not want to sacrifice accuracy.
