What IRS Form 1040-ES (2023) Is For
Form 1040-ES is the IRS form used to calculate estimated taxes for the current tax year when income is not subject to federal income tax withholding. It helps taxpayers determine how much tax they must pay throughout the tax year to avoid penalties. Individuals who earn income without taxes withheld, including self-employed workers, independent contractors, S corporation owners, and those with capital gains or Social Security benefits, must use it to make accurate estimated tax payments.
When You’d Use IRS Form 1040-ES (2023)
You use this form when you expect to owe at least one thousand dollars in income taxes after subtracting withholding and refundable credits. Taxpayers must pay estimated taxes if they receive earnings without taxes withheld, such as contract work or investment income. You also use it when prior-year-covered income was taxed too lightly, and you expect a similar situation in the current tax year.
Key Rules or Details for 2023
- Estimated tax requirement: Taxpayers must pay estimated taxes if they expect to owe enough tax that exceeds withholding and refundable credits. This requirement applies whenever income is earned without taxes withheld.
- Safe harbor threshold: You can avoid penalties by paying ninety percent of your current tax liability or one hundred percent of the previous year's total tax. This system protects taxpayers with fluctuating income.
- High-income rule: Taxpayers with a high adjusted gross income must pay 110 percent of the prior year's tax. This rule ensures that there are enough estimated payments when income increases.
- Quarterly schedule: Quarterly estimated tax payments follow four due dates throughout the tax year. Each payment period covers different months and requires accurate quarterly taxes.
- Withholding flexibility: Federal income tax withholding counts as paid evenly throughout the year. This helps taxpayers avoid penalties if they adjust withholding late.
- Special rules: Farmers, fishermen, and certain S corporation owners follow different estimated payment requirements. These rules are particularly useful when earnings are seasonal or unpredictable.

Step-by-Step (High Level)
Step 1: Estimate annual income
You begin by estimating all taxable income for the current tax year, including wages, self-employment earnings, capital gains, and other taxable income. This helps determine the amount of tax you are required to pay.
Step 2: Calculate adjustments and deductions
You calculate adjusted gross income by subtracting allowed deductions from gross income. You then estimate the taxable income that determines the applicable tax rate for the year.
Step 3: Figure federal tax and other taxes
You apply the correct tax rate to your taxable income and add other taxes, such as self-employment tax or the taxable part of Social Security benefits. This produces your estimated total tax.
Step 4: Apply withholding and refundable credits
You subtract taxes withheld and refundable credits from your estimated total tax. This determines how much tax you still owe for the year through estimated payments.
Step 5: Divide into quarterly payments
You divide the remaining tax into quarterly payment amounts. Each quarterly estimated tax payment must be paid by the correct due date to avoid penalties.

Common Mistakes and How to Avoid Them
- Underestimating income: Taxpayers often underestimate earnings and underpay estimated taxes, which increases the risk of penalties. You can avoid this by reviewing your income monthly and adjusting your estimated payments accordingly.
- Ignoring self-employment tax: Many self-employed taxpayers overlook the self-employment tax when calculating estimated payments. You can avoid such errors by including all payroll taxes when estimating liability.
- Missing due dates: Missing quarterly payment deadlines increases the estimated tax penalty. You can avoid this by setting reminders before each due date to ensure timely payment.
- Incorrect withholding assumptions: Some taxpayers assume that taxes withheld will cover new earnings, resulting in underpayment. You can avoid this by checking the tax withholding regularly and adjusting it as needed.
- Not updating estimates: Income changes during the year require updated estimates to avoid penalties. You can prevent this by recalculating your estimated income tax before the next quarter begins.

What Happens After You File
After you pay quarterly estimated taxes, the IRS credits each estimated tax payment to your account for the current tax year. These tax payments appear on your tax return and reduce the total tax you owe.
If you pay more than required, the IRS applies the overpayment to the following year or issues a refund. If you pay less, you may receive an estimated tax penalty unless you meet safe harbor rules or qualify for reasonable cause or other unusual circumstance relief.
