Introduction This chapter discusses how to pay your tax as you earn or receive income during the year. In general, the federal income tax is a pay-as-you-go tax. There are two ways to pay as you go. Withholding. If you are an employee, your employer probably withholds income tax from your pay. Tax may also be withheld from certain other income, such as pensions, bonuses, commissions, and gambling winnings. The amount withheld is paid to the IRS in your name. Estimated tax. If you don’t pay your tax through withholding, or don’t pay enough tax that way, you may have to pay estimated tax. People who are in business for themselves will generally have to pay their tax this way. Also, you may have to pay estimated tax if you receive income such as dividends, interest, capital gains, rent, and royalties. Estimated tax is used to pay not only income tax, but self-employment tax and alternative minimum tax as well. This chapter explains these methods. In addition, it also explains the following. Credit for withholding and estimated tax. When you file your 2025 income tax return, take credit for all the income tax withheld from your salary, wages, pensions, etc., and for the estimated tax you paid for 2025. Also take credit for any excess social security or railroad retirement tax withheld. See Pub. 505. Underpayment penalty. If you didn’t pay enough tax during the year, either through withholding or by making estimated tax payments, you may have to pay a penalty. In most cases, the IRS can figure this penalty for you. See Underpayment Penalty for 2025 at the end of this chapter.

This section explains the rules for withholding tax from each of these types of income. This section also covers backup withholding on interest, dividends, and other payments. Salaries and Wages Income tax is withheld from the pay of most employees. Your pay includes your regular pay, bonuses, commissions, and vacation allowances. It also includes reimbursements and other expense allowances paid under a nonaccountable plan. See Supplemental Wages , later, for more information about reimbursements and allowances paid under a nonaccountable plan. If your income is low enough that you won’t have to pay income tax for the year, you may be exempt from withholding. This is explained under Exemption From Withholding , later. You can ask your employer to withhold income tax from noncash wages and other wages not subject to withholding. If your employer doesn’t agree to withhold tax, or if not enough is withheld, you may have to pay estimated tax, as discussed later under Estimated Tax for 2026 . Military retirees. Military retirement pay is treated in the same manner as regular pay for income tax withholding purposes, even though it is treated as a pension or annuity for other tax purposes. Household workers. If you are a household worker, you can ask your employer to withhold income tax from your pay. A household worker is an employee who performs household work in a private home, local college club, or local fraternity or sorority chapter. Tax is withheld only if you want it withheld and your employer agrees to withhold it. If you don’t have enough income tax withheld, you may have to pay estimated tax, as discussed later under Estimated Tax for 2026 . Farmworkers. Generally, income tax is withheld from your cash wages for work on a farm unless your employer: Pays you cash wages of less than $150 during the year, and Has expenditures for agricultural labor totaling less than $2,500 during the year. Differential wage payments. When employees are on leave from employment for military duty, some employers make up the difference between the military pay and civilian pay. Payments to an employee who is on active duty for a period of more than 30 days will be subject to income tax withholding, but not subject to social security, Medicare, or federal unemployment (FUTA) tax withholding. The wages and withholding will be reported on Form W-2, Wage and Tax Statement. Determining Amount of Tax Withheld Using Form W-4 The amount of income tax your employer withholds from your regular pay depends on the following two things. The amount you earn in each payroll period. The information you give your employer on Form W-4. Form W-4 includes steps to help you figure your withholding. Complete Steps 2 through 4 only if they apply to you. Step 1. Enter your personal information including your filing status. Step 2. Complete this step if you have more than one job at the same time or are married filing jointly and you and your spouse both work. Step 3. Complete this step if you claim dependents and other credits. Step 4. Complete this optional step to make other adjustments. —Other income —Deductions —Extra withholding New Job When you start a new job, you must fill out Form W-4 and give it to your employer. Your employer should have copies of the form. If you need to change the information later, you must fill out a new form. If you work only part of the year (for example, you start working after the beginning of the year), too much tax may be withheld. You may be able to avoid overwithholding if your employer agrees to use the part-year method. See Part-Year Method in chapter 1 of Pub. 505 for more information. Employee also receiving pension income. If you receive pension or annuity income and begin a new job, you will need to file Form W-4 with your new employer. However, you can choose to split your withholding between your pension and job in any manner. Changing Your Withholding During the year, changes may occur to your marital status, adjustments, deductions, or credits you expect to claim on your tax return. When this happens, you may need to give your employer a new Form W-4 to change your withholding status. If a change in personal circumstances reduces the amount of withholding you are entitled to claim, you are required to give your employer a new Form W-4 within 10 days after the change occurs. Changing your withholding for 2027. If events in 2026 will change the amount of withholding you should claim for 2027, you must give your employer a new Form W-4 by December 1, 2026. If the event occurs in December 2026, submit a new Form W-4 within 10 days. Checking Your Withholding After you have given your employer a Form W-4, you can check to see whether the amount of tax withheld from your pay is too little or too much. If too much or too little tax is being withheld, you should give your employer a new Form W-4 to change your withholding. You should try to have your withholding match your actual tax liability. If not enough tax is withheld, you will owe tax at the end of the year and may have to pay interest and a penalty. If too much tax is withheld, you will lose the use of that money until you get your refund. Always check your withholding if there are personal or financial changes in your life or changes in the law that might change your tax liability. Note: You can’t give your employer a payment to cover withholding on salaries and wages for past pay periods or a payment for estimated tax.
