Fill out IRS Form 1040-ES Online in 2026

Form 1040-ES is used to calculate and pay estimated tax on income that isn't subject to withholding. This includes earnings from self-employment, interest, dividends, and rental income. People who do not have enough tax withheld from their salary or who receive income without withholding need to complete this form to avoid underpayment penalties. It helps you plan and pay taxes quarterly, ensuring you meet your tax obligations throughout the year.

The Form 1040-ES is crucial for managing your taxes throughout the year. Here's what it's designed for:

• To estimate your taxes for the current year.
• To make quarterly tax payments if you're self-employed or have other income without withholding.
• To avoid underpayment penalties by accurately calculating payments.

1. Gather your records:

• Have your prior year's tax return (Form 1040) ready.

• Collect documents showing expected income — W-2s, 1099s, business earnings, and investment income.

2. Estimate your income and deductions (Worksheet, lines 1–7):

• Line 1: Enter your expected adjusted gross income for the year.

• Lines 2–4: Enter expected adjustments to income (IRA deductions, self-employment tax, etc.).

• Lines 5–6: Enter your expected deductions — either the standard deduction for your filing status or your estimated itemized deductions.

• Line 7: Subtract deductions from AGI to get your estimated taxable income.

3. Calculate your estimated tax (Worksheet, lines 8–11b):

• Lines 8–9: Figure your expected income tax and subtract estimated credits.

• Lines 10–11a: Add self-employment tax and any other taxes you expect to owe.

• Line 11b: This is your total estimated tax for the year.

4. Subtract withholdings (Worksheet, lines 12–13):

• Line 12: Enter expected federal income tax withholding from wages and other sources.

• Line 13: Enter any refundable credits you expect (earned income credit, etc.).

5. Determine your required payment (Worksheet, lines 14a–17):

• Line 14a: Subtract withholdings and credits from total tax to find your balance due.

• Lines 14b–17: Compare your current year's estimated tax with your prior year's tax to determine the required annual payment using the safe harbor rules.

6. Complete the payment voucher:

• Enter your name, address, and Social Security number.

• Enter the quarterly payment amount (one-quarter of your required annual payment).

7. Submit your payment:

• Mail the voucher with a check or money order to the IRS address listed for your state.

• Or pay electronically through IRS Direct Pay, EFTPS, or by credit/debit card at irs.gov.

Form 1040-ES is for anyone who expects to owe $1,000 or more in tax after subtracting withholdings and refundable credits. This typically includes self-employed individuals, freelancers, gig workers, small business owners, and those earning income from investments, rent, or alimony.

The IRS uses this form to collect taxes quarterly rather than waiting until the annual return is filed.

Not everyone needs to fill out Form 1040-ES.

If you expect to owe less than $1,000 in taxes for the year after subtracting your withholdings and credits, you might not need to use this form. Additionally, individuals who receive salaries and wages with taxes automatically withheld by their employer typically do not need to use Form 1040-ES.

The Form 1040-ES deadline is quarterly. The due dates are April 15, June 16, September 15 of the current year and January 15 of the following year. If a due date falls on a weekend or holiday, the deadline moves to the next business day.

If you're making estimated tax payments, marking these dates on your calendar helps ensure your payments are timely and avoid penalties.
