What Form 1040-ES Is For
Form 1040-ES helps taxpayers calculate and pay estimated taxes on income that does not receive withholding from an employer. It applies to income such as self-employment income, capital gains, business earnings, and other taxable income that requires estimated tax payments during the tax year.
When You’d Use Form 1040-ES
You use this form when you expect to owe a tax of at least one thousand dollars after withholding and refundable credits. It also applies when estimated payments do not cover enough tax to meet safe harbor rules or when a self-employed person receives income throughout the year.
Key Rules or Details for 2025
- Safe harbor rules: Safe harbor rules allow taxpayers to avoid penalties when estimated payments equal 90% of the current total tax or 100% of the prior year's figure. These protections help you pay estimated taxes properly.
- Quarterly deadlines: Each estimated tax payment is due on the IRS deadlines during the tax year, and missing a quarterly payment can result in underpayment penalties. These deadlines help ensure payments are made on time.
- Self-employment tax: Self-employed individuals calculate the SE tax using their net earnings and must pay self-employment tax, in addition to income tax, through estimated taxes. This applies to sole proprietors and independent contractors.
- Adjusted gross income limits: Higher-income taxpayers follow special rules requiring 110 percent of the prior tax liability for safe harbor protection. This rule prevents taxpayers from underpaying their taxes.
- Unequal payments: The IRS allows unequal payments when income changes during the year, but taxpayers must use the annualized installment method. This helps reduce penalties when income arrives irregularly.

Step-by-Step (High Level)
Step 1: Gather income and deduction information
Collect expected income, deductions, and credits, including self-employment income and net profit from Schedule C. This information helps estimate the amount of tax you owe during the tax year.
Step 2: Estimate adjusted gross income
Use your earnings, deductions, and expected changes to estimate adjusted gross income. This estimate helps determine the amount of tax you need to pay through estimated payments.
Step 3: Calculate taxable income
Subtract deductions from your adjusted gross income to figure your taxable income. This step shows how much tax applies before credits and payments.
Step 4: Figure total tax and credits
Apply the correct tax rate to your taxable income to calculate total tax, including self-employment tax when required. Subtract refundable credits to determine how much tax remains for income tax purposes during the tax year.
Step 5: Determine required estimated payments
Compare your calculated tax with withholding and refundable credits to see how much tax you still owe. Divide the remaining amount into each quarterly payment to avoid penalties and stay current with IRS requirements.
Step 6: Make each estimated tax payment
Submit each payment electronically or by voucher before the deadline to avoid underpayment penalties. Keep records of every payment made so you can file your annual return accurately for income tax purposes.

Common Mistakes and How to Avoid Them
- Missing income sources: Taxpayers sometimes overlook investment income, capital gains, or business earnings, which can cause them to owe tax unexpectedly. You can avoid this mistake by reviewing all income streams and checking prior returns to confirm nothing is overlooked.
- Incorrect SE tax calculations: Self-employed individuals sometimes miscalculate SE tax by skipping the net earnings adjustment. You can prevent this error by using IRS worksheets that calculate SE tax and show how much tax applies.
- Relying solely on withholding: Some taxpayers assume withholding covers enough tax, even with extra income, which can result in a larger tax bill later. You can avoid penalties by reviewing withholding and estimating whether estimated taxes are still required.
- Ignoring special rules: Higher earners sometimes overlook the higher safe harbor percentage, resulting in underpayment penalties. You can avoid this issue by checking adjusted gross income thresholds and applying the correct safe harbor rule.
- Unequal payments without adjustments: Taxpayers with uneven earnings sometimes send unequal payments without using the annualized method. You can prevent penalties by using the calculation method that matches how you receive income during the tax year.

What Happens After You File
The IRS applies each estimated payment to your account and credits it toward your annual return. When you file Form 1040, these payments reduce your tax liability, and the IRS issues a refund or requests payment depending on how much tax remains due.
