FAQs

For the W-4 calculator to estimate how much you should withhold, be sure to have on hand your paycheck info and estimates on any other income such as from a small business, interest, dividends, stocks, and more. You’ll also be asked about dependents and deductions.

Updating your W-4 changes how much federal tax your employer withholds from each paycheck. Increasing your withholding typically raises your tax refund or lowers what you owe at tax time, but it reduces your take‑home pay. Lowering your withholding increases your take‑home pay now but may reduce your refund or lead to a balance due.

Not at this time. This calculator only estimates federal tax withholding.

Yes, you can use the calculator to include self‑employment or freelance income when estimating your taxes. However, if you don’t also have wage income from an employer who issues a W‑2, you won’t be able to use the calculator to adjust your refund amount or generate a W-4 because those features require wage income.

Yes. You can submit a new W-4 to your employer at any time during the year.

It’s a good idea to review and update your W-4 each year or whenever a major life change happens, such as having a child, starting a new job, or other significant financial changes.

Yes. If you qualify for the head of household filing status, you can indicate it on your W-4. The W-4 calculator will ask questions about your situation to help determine your filing status and fill out the form accordingly.

In many cases, it’s possible to set your federal withholding to zero. The W-4 calculator can show you what your refund or balance due would look like with no withholding. However, be aware that you may face penalties if your balance due at tax time is too high.
