What Form 1040-ES (2021) Is For
Form 1040-ES is used to calculate and pay estimated taxes during the tax year on income that does not have duties withheld. It applies to income such as self-employment income, investment earnings, rental income, and the taxable part of Social Security benefits.
Most wage earners rely on taxes withheld from paychecks, but self-employed individuals, sole proprietors, independent contractors, and small business owners must pay estimated taxes directly. The form helps determine the amount of tax liability you owe for the current tax year and whether estimated tax payments are required to avoid penalties.
When You’d Use Form 1040-ES (2021)
You use Form 1040-ES when you expect to owe at least one thousand dollars after subtracting withholding and refundable credits on your annual return. This requirement applies when taxes withheld and refundable credits are not enough to cover the total tax for income tax purposes.
Resident alien taxpayers, self-employed individuals, sole proprietors, and independent contractors often pay estimated taxes because they do not have payroll taxes withheld from their income. If your prior tax year covered all twelve months, special rules also allow safe harbor protection based on prior-year tax.
Key Rules or Details for 2021
- Safe harbor rules: You can avoid penalties by paying at least ninety percent of your current tax liability or one hundred percent of your prior year tax when making estimated tax payments for the current tax year.
- High-income threshold: Taxpayers with higher adjusted gross income must pay 110 percent of the prior year's total tax, which ensures sufficient tax is paid even when income increases.
- Quarterly schedule: The IRS sets specific due dates for each quarterly payment, and each due date is based on when you earn income rather than evenly divided quarters.
- Income changes: If earnings rise significantly due to capital gains or self-employment income, you must increase payments by the next quarter to avoid underpayment penalties.
- Payment methods: Payments can be made electronically or by voucher. Careful tracking ensures that taxes withheld and payments are correctly applied to the expected tax bill.

Step-by-Step (High Level)
Step 1: Gather Your Financial Records
Collect your prior tax return, income statements, and documents showing deductions and credits so you can calculate how much tax you owe for the current tax year accurately.
Step 2: Complete the Estimated Tax Worksheet
Estimate taxable income by adding expected earnings, subtracting deductions, and applying the appropriate tax rate to determine total tax and whether estimated tax payment requirements apply.
Step 3: Determine Your Required Annual Payment
Compare ninety percent of the current tax with the applicable prior year tax to determine the safe harbor amount needed to avoid penalties when paying estimated taxes for the year.
Step 4: Calculate Your Quarterly Payments
Divide your required annual amount into quarterly estimated taxes so each quarterly payment aligns with IRS requirements and reflects any changes in income throughout the year.
Step 5: Submit Your Payments
Make payments electronically or by mail using the appropriate IRS form voucher, and ensure each payment is credited to the correct tax year to avoid issues with future filings.

Common Mistakes and How to Avoid Them
- Underestimating income: Many taxpayers miscalculate earnings and underpay, but you can avoid this by reviewing revenue often and increasing payments when income or capital gains rise unexpectedly. Both actions reduce the risk of penalties.
- Missing due dates: Late payments may result in increased underpayment penalties; however, you can prevent problems by setting reminders and scheduling electronic payments before each quarterly due date arrives.
- Ignoring self-employment tax: Some taxpayers omit self-employment tax from calculations, but you can avoid this by including SE tax on net earnings to ensure enough tax is paid for the year.
- Relying solely on withholding: Withholding may not cover additional income, yet you can prevent a tax bill by comparing taxes withheld with the total tax to decide whether making estimated tax payments is necessary.
- Using outdated figures: Outdated tax amounts cause inaccurate estimates, but you can avoid issues by using the updated IRS form and current tax year rules so payments match actual liability.

What Happens After You File
After you make estimated tax payments, the IRS applies each payment to the current tax year under your Social Security number. When you file your annual return, all fees and taxes withheld are compared with the total tax to determine whether you owe or receive a refund.
If you do not pay enough tax throughout the year, you may receive an estimated tax penalty unless reasonable cause or an unusual circumstance applies. If income changes or payment errors occur, you can correct them on the annual return without willful neglect penalties when reasonable cause exists.
