2026 Form 1040-ES Estimated Tax for Individuals Purpose of This Package Use Form 1040-ES to figure and pay your estimated tax for 2026. Estimated tax is the method used to pay tax on income that isn’t subject to withholding (for example, earnings from self-employment, including gig economy work, interest, dividends, rents, alimony, etc.). In addition, if you don’t elect voluntary withholding, you should make estimated tax payments on other taxable income, such as unemployment compensation and the taxable part of your social security benefits. Preprinted vouchers. If you made estimated tax payments for 2025, this package may contain vouchers that are preprinted with your name, address, and SSN. If your name or SSN isn’t correct, make the necessary changes on the vouchers. Cross out the name and SSN of a deceased or divorced spouse. Change of address. If your address has changed, file Form 8822, to update your record. Future developments. For the latest information about developments related to Form 1040-ES and its instructions, such as legislation enacted after they were published, go to IRS.gov/Form1040ES. Who Must Make Estimated Tax Payments The estimated tax rules apply to: • U.S. citizens and resident aliens; • Residents of Puerto Rico, the U.S. Virgin Islands, Guam, the Commonwealth of the Northern Mariana Islands, and American Samoa; and • Nonresident aliens (use Form 1040-ES (NR)). General Rule In most cases, you must pay estimated tax for 2026 if both of the following apply. 1. You expect to owe at least $1,000 in tax for 2026, after subtracting your withholding and refundable credits. 2. You expect your withholding and refundable credits to be less than the smaller of: a. 90% of the tax to be shown on your 2026 tax return, or b. 100% of the tax shown on your 2025 tax return. Your 2025 tax return must cover all 12 months. Note: These percentages may be different if you have income from farming or fishing or are a higher income taxpayer. See Special Rules, later. TIP Exception. You don’t have to pay estimated tax for 2026 if you were a U.S. citizen or resident alien for all of 2025 and you had no tax liability for the full 12-month 2025 tax year. You had no tax liability for 2025 if your total tax was zero or you didn’t have to file an income tax return. Special Rules There are special rules for those who have income from farming and fishing, for certain household employers, and for certain higher income taxpayers. Farming and fishing. If at least two-thirds of your gross income for 2025 or 2026 is from farming or fishing, substitute 662/3% for 90% in (2a) under General Rule. Household employers. When estimating the tax on your 2026 tax return, include your household employment taxes if either of the following applies. • You will have federal income tax withheld from wages, pensions, annuities, gambling winnings, or other income. • You would be required to make estimated tax payments to avoid a penalty even if you didn’t include household employment taxes when figuring your estimated tax. Higher income taxpayers. If your adjusted gross income (AGI) for 2025 was more than $150,000 ($75,000 if your filing status for 2026 is married filing separately), substitute 110% for 100% in (2b) under General Rule, earlier. If at least two-thirds of your gross income for 2025 or 2026 is from farming or fishing, this rule doesn’t apply. Increase Your Withholding If you also receive salaries and wages, you may be able to avoid having to make estimated tax payments on your other income by asking your employer to take more tax out of your earnings. To do this, file a new Form W-4, Employee’s Withholding Certificate, with your employer. Generally, if you receive a pension or annuity, you can use Form W-4P, Withholding Certificate for Periodic Pension or Annuity Payments, to start or change your withholding from these payments. You can also choose to have federal income tax withheld from certain government payments (see Form W-4V, Voluntary Withholding Request) or from nonperiodic payments and eligible rollover distributions (see Form W-4R, Withholding Certificate for Nonperiodic Payments and Eligible Rollover Distributions). You can use the Tax Withholding Estimator at IRS.gov/W4App to determine whether you need to have your withholding increased or decreased. Additional Information You May Need You can find most of the information you will need in Pub. 505, Tax Withholding and Estimated Tax, and in the 2025 Instructions for Form 1040.

How To Figure Your Estimated Tax You will need: • The 2026 Estimated Tax Worksheet; • The Instructions for the 2026 Estimated Tax Worksheet; • The 2026 Tax Rate Schedules; and • Your 2025 tax return and instructions to use as a guide to figuring your income, deductions, and credits (but be sure to consider the items listed under What's New, earlier). Matching estimated tax payments to income. If you receive your income unevenly throughout the year (for example, because you operate your business on a seasonal basis or you have a large capital gain late in the year), you may be able to lower or eliminate the amount of your required estimated tax payment for one or more periods by using the annualized income installment method. See chapter 2 of Pub. 505 for details. Changing your estimated tax. To amend or correct your estimated tax, see How To Amend Estimated Tax Payments, later. You can’t make joint estimated tax payments if you or your spouse is a nonresident alien, you are separated under a decree of divorce or separate maintenance, or you and your spouse have different tax years. Additionally, individuals who are in registered domestic partnerships, civil unions, or other similar formal relationships that aren’t marriages under state law cannot make joint estimated tax payments. These individuals can take credit only for the estimated tax payments that they made. Payment Due Dates You can pay all of your estimated tax by April 15, 2026, or in four equal amounts by the dates shown below. CAUTION ! 4 Form 1040-ES (2026)

1st payment . . . . . . . . . . . . . . . . . April 15, 2026 2nd payment . . . . . . . . . . . . . . . . June 15, 2026 3rd payment . . . . . . . . . . . . . . . . . Sept. 15, 2026 4th payment . . . . . . . . . . . . . . . . . Jan. 15, 2027* * You don’t have to make the payment due January 15, 2027, if you file your 2026 tax return by February 1, 2027, and pay the entire balance due with your return. If you mail your payment and it is postmarked by the due date, the date of the U.S. postmark is considered the date of payment. If your payments are late or you didn’t pay enough, you may be charged a penalty for underpaying your tax. See When a Penalty Is Applied, later. Recent clarification to the U.S. Postal Service (USPS) postmark rules makes clear that for purposes of the “timely mailing treated as timely filing/paying” rule for tax returns and payments, the postmarked date of a return/payment is the date the return is processed at a facility. This date may or may not be the date you drop your payment off in the mailbox or at a USPS location. You can make more than four estimated tax payments. To do so, make a copy of one of your unused estimated tax payment vouchers, fill it in, and mail it with your payment. If you make more than four payments, to avoid a penalty, make sure the total of the amounts you pay during a payment period is at least as much as the amount required to be paid by the due date for that period. For other payment methods, see How To Pay Estimated Tax, later. No income subject to estimated tax during first pay- ment period. If, after March 31, 2026, you have a large change in income, deductions, additional taxes, or credits that requires you to start making estimated tax payments, you should figure the amount of your estimated tax payments by using the annualized income installment method, explained in chapter 2 of Pub. 505. If you use the annualized income installment method, file Form 2210, including Schedule AI, with your 2026 tax return even if no penalty is owed. Farming and fishing. If at least two-thirds of your gross income for 2025 or 2026 is from farming or fishing, you can do one of the following. • Pay all of your estimated tax by January 15, 2027. • File your 2026 Form 1040 or 1040-SR by March 1, 2027, and pay the total tax due. In this case, 2026 estimated tax payments aren’t required to avoid a penalty. Fiscal year taxpayers. You are on a fiscal year if your 12-month tax period ends on any day except December 31. Due dates for fiscal year taxpayers are the 15th day of the 4th, 6th, and 9th months of your current fiscal year and the 1st month of the following fiscal year. If any payment date falls on a Saturday, Sunday, or legal holiday, use the next business day. See Pub. 509, Tax Calendars, for a list of all legal holidays. CAUTION ! TIP Name Change If you changed your name because of marriage, divorce, etc., and you made estimated tax payments using your former name, attach a statement to the front of your 2026 paper tax return. On the statement, show all of the estimated tax payments you (and your spouse, if filing jointly) made for 2026 and the name(s) and SSN(s) under which you made the payments. Be sure to report the change to your local Social Security Administration office before filing your 2026 tax return. This prevents delays in processing your return and issuing refunds. It also safeguards your future social security benefits. For more details, call the Social Security Administration at 800-772-1213 (TTY/TDD 800-325-0778). How To Amend Estimated Tax Payments To change or amend your estimated tax payments, refigure your total estimated tax payments due (see the 2026 Estimated Tax Worksheet). Then, to figure the payment due for each remaining payment period, see Amended estimated tax in chapter 2 of Pub. 505. If an estimated tax payment for a previous period is less than one-fourth of your amended estimated tax, you may owe a penalty when you file your return. When a Penalty Is Applied In some cases, you may owe a penalty when you file your return. The penalty is imposed on each underpayment for the number of days it remains unpaid. A penalty may be applied if you didn’t pay enough estimated tax for the year or you didn’t make the payments on time or in the required amount. The penalty may be waived under certain conditions. See the Instructions for Form 2210 for details. How To Pay Estimated Tax Pay Online Paying online is convenient and secure and helps make sure we get your payments on time.

To find out about the different cash payment methods, go to IRS.gov/PayCash. Don’t send cash payments through the mail. Pay by Check or Money Order Using the Estimated Tax Payment Voucher Before submitting a payment through the mail using the estimated tax payment voucher, please consider alternative methods. One of our safe, quick, and easy online payment options might be right for you. If you choose to mail in your payment, there is a separate estimated tax payment voucher for each due date. The due date is shown in the upper-right corner. Complete and send in the voucher only if you are making a payment by check or money order. If you and your spouse plan to file separate returns, file separate vouchers instead of a joint voucher. To complete the voucher, do the following. • Print or type your name, address, and SSN in the space provided on the estimated tax payment voucher. Enter your SSN even if your SSN does not authorize employment or if you have been issued an SSN that authorizes employment and you lose your employment authorization. If you have an ITIN, enter it wherever your SSN is requested. An ITIN will not be issued to you once you have been issued an SSN. If you received your SSN after previously using an ITIN, stop using your ITIN. Use your SSN instead. If filing a joint voucher, also enter your spouse’s name and SSN. List the names and SSNs in the same order on the joint voucher as you will list them on your joint return. • Enter in the box provided on the estimated tax payment voucher only the amount you are sending in by check or money order. When making payments of estimated tax, be sure to take into account any 2025 overpayment that you choose to credit against your 2026 tax, but don’t include the overpayment amount in this box. • Make your check or money order payable to “United States Treasury.” Don’t send cash. To help process your payment accurately, enter the amount on the right side of the check like this: $ XXX.XX. Don’t use dashes or lines (for example, don’t enter “$ XXX—” or “$ XXX xx/100”). • Enter “2026 Form 1040-ES” and your SSN on your check or money order. If you are filing a joint estimated tax payment voucher, enter the SSN that you will show first on your joint return. • Enclose, but don’t staple or attach, your payment with the estimated tax payment voucher. Notice to taxpayers presenting checks. When you provide a check as payment, you authorize us either to use information from your check to make a one-time electronic funds transfer from your account or to process the payment as a check transaction. When we use information from your check to make an electronic funds transfer, funds may be withdrawn from your account as soon as the same day we receive your payment, and you will not receive your check back from your financial institution.

On line 10, enter the total of those taxes, subject to the following two exceptions. Exception 1. Include household employment taxes from Schedule 2 (Form 1040), line 9, on this line only if: • You will have federal income tax withheld from wages, pensions, annuities, gambling winnings, or other income; or • You would be required to make estimated tax payments (to avoid a penalty) even if you didn’t include household employment taxes when figuring your estimated tax. If you meet either of the above, include the total of your household employment taxes on line 10. Exception 2. Because the following taxes are not required to be paid until the due date of your income tax (not including extensions), do not include them on line 10. • Uncollected social security, Medicare tax, or RRTA tax on tips or group-term life insurance (Schedule 2, line 13). • Recapture of federal mortgage subsidy (Schedule 2, line 17b). • Excise tax on excess golden parachute payments (Schedule 2, line 17k). • Excise tax on insider stock compensation from an expatriated corporation (Schedule 2, line 17m).

Note: If at least two-thirds of your gross income for 2025 was from farming or fishing, this doesn’t apply. • If you will file a joint return for 2026 but you didn’t file a joint return for 2025, add the tax shown on your 2025 return to the tax shown on your spouse’s 2025 return and enter the total on line 12b. • If you filed a joint return for 2025 but you will not file a joint return for 2026, first figure the tax both you and your spouse would have paid had you filed separate returns for 2025 using the same filing status as for 2026. Then multiply the tax on the joint return by a fraction, the numerator being the tax you would have paid had you filed a separate return, over the total tax you and your spouse would have paid had you filed separate returns. Enter this amount on line 12b. • If you didn’t file a return for 2025 or your 2025 tax year was less than 12 full months, don’t complete line 12b. Instead, enter the amount from line 12a on line 12c.
