Purpose of Form
Complete Form W-4 so that your employer can withhold the correct federal income tax from your pay. If too little is withheld, you will generally owe tax when you file your tax return and may owe a penalty. If too much is withheld, you will generally be due a refund. Complete a new Form W-4 when changes to your personal or financial situation would change the entries on the form. For more information on withholding and when you must furnish a new Form W-4, see Pub. 505.
Exemption from withholding. You may claim exemption from withholding for 2020 if you meet both of the following conditions: you had no federal income tax liability in 2019 and you expect to have no federal income tax liability in 2020. You had no federal income tax liability in 2019 if (1) your total tax on line 16 on your 2019 Form 1040 or 1040-SR is zero (or less than the sum of lines 18a, 18b, and 18c), or (2) you were not required to file a return because your income was below the filing threshold for your correct filing status. If you claim exemption, you will have no income tax withheld from your paycheck and may owe taxes and penalties when you file your 2020 tax return. To claim exemption from withholding, certify that you meet both of the conditions above by writing “Exempt” on Form W-4 in the space below Step 4(c Then, complete Steps 1(a), 1(b), and 5. Do not complete any other steps. You will need to submit a new Form W-4 by February 16, 2021.
Your privacy. If you prefer to limit information provided in Steps 2 through 4, use the online estimator, which will also increase accuracy.
As an alternative to the estimator: if you have concerns with Step 2(c), you may choose Step 2(b); if you have concerns with Step 4(a), you may enter an additional amount you want withheld per pay period in Step 4(c If this is the only job in your household, you may instead check the box in Step 2(c), which will increase your withholding and significantly reduce your paycheck (often by thousands of dollars over the year
When to use the estimator. Consider using the estimator at www.irs.gov/W4App if you: 1. Expect to work only part of the year; 2. Have dividend or capital gain income, or are subject to additional taxes, such as the additional Medicare tax; 3. Have self-employment income (see below); or 4. Prefer the most accurate withholding for multiple job situations.
Self-employment. Generally, you will owe both income and self-employment taxes on any self-employment income you receive separate from the wages you receive as an employee. If you want to pay these taxes through withholding from your wages, use the estimator at www.irs.gov/W4App to figure the amount to have withheld.
Nonresident alien. If you’re a nonresident alien, see Notice 1392, Supplemental Form W-4 Instructions for Nonresident Aliens, before completing this form.
