A federal estimated tax payment is a quarterly payment you send to the IRS when you owe taxes but no employer is withholding from your paycheck
If you're self-employed, a freelancer, a business owner, or you have income that isn't subject to withholding—like rental income, investment gains, or retirement distributions—the IRS expects you to pay taxes four times a year instead of once at tax time. These are your estimated tax payments. You calculate what you think you'll owe for the full year, divide it by four, and send that amount to the IRS on specific dates.
The IRS calls this estimated tax, and it's a legal obligation, not optional. If you don't pay enough throughout the year, you'll owe the balance when you file your return, plus potential penalties and interest. If you pay too much, you'll get a refund.
Key Takeaways
- Estimated tax payments are due four times a year on specific dates: April 15, June 15, September 15, and January 15 of the following year.
- You calculate your estimated tax by predicting your income for the year, subtracting deductions, and dividing the result by four.
- You can pay by mail using Form 1040-ES, online through IRS Direct Pay, by phone, or through an authorized payment processor.
- If you underpay estimated taxes, you may owe penalties and interest when you file your return, even if you get a refund overall.
- Self-employed people, business owners, and anyone with significant non-withheld income should check whether they need to make these payments.
Who has to make estimated tax payments
You're required to make estimated tax payments if you expect to owe $1,000 or more in federal income tax after accounting for withholding and tax credits. This typically applies to self-employed people, sole proprietors, partners in partnerships, S-corporation shareholders, and people with substantial income from sources like rental properties, investments, or retirement account distributions.
If you're an employee with a W-2 job and your employer withholds taxes from your paycheck, you usually don't need to make estimated payments—unless you have significant side income or other non-withheld income on top of your job. The rule is about total tax owed, not the source of the income.
Farmers and fishermen have different rules and different payment deadlines, so check IRS Publication 505 if that applies to you.
The four payment dates and how to calculate what you owe
The IRS sets four payment deadlines each year. For the 2024 tax year, they fall on April 15, June 15, September 15, and January 15, 2025. If a deadline falls on a weekend or federal holiday, the due date moves to the next business day. The IRS website lists the exact dates each year.
To calculate your payment, estimate your total income for the year, subtract deductions you expect to claim, and multiply by your expected tax rate. Then divide that number by four. If your income is uneven across the year—for example, you earn more in summer than winter—you can use the annualized income method to pay different amounts each quarter, which may reduce penalties if you underpay early in the year.
Form 1040-ES, which the IRS provides free, includes a worksheet to walk you through the calculation. You don't have to file the form with the IRS; it's just a tool to help you figure out what to send.
How to send your estimated tax payment to the IRS
You have several options for paying. IRS Direct Pay is free and lets you pay directly from your bank account through the IRS website. You'll need your Social Security number or employer ID number, your filing status, and the amount you want to pay. The payment posts within one business day.
The Electronic Federal Tax Payment System (EFTPS) is another free option run by the U.S. Department of the Treasury. You enroll once, then schedule payments online or by phone. Payments typically post within one business day.
You can also pay by credit or debit card through an authorized payment processor, though they charge a fee (usually 1.5 to 2 percent of the payment). If you prefer to mail a check, include Form 1040-ES with your payment and send it to the IRS address listed on the form for your state. Mail payments take longer to process and are riskier if lost.
What happens if you underpay or overpay
If you pay less than you owe, you'll owe the difference when you file your tax return in April. The IRS will also charge you underpayment penalties and interest on the shortfall. The penalty amount depends on how much you underpaid and how late you were in paying it. Even if you get a refund overall because you overpaid in other ways, you can still owe an underpayment penalty.
If you pay more than you owe, you'll get a refund when you file your return. You can choose to have the refund applied to your next year's estimated tax payments instead of receiving it as a check or direct deposit.
The IRS provides a worksheet in Publication 505 to help you figure out whether you'll face a penalty, and it explains safe harbor rules—thresholds that protect you from penalties if you meet them.
Adjusting payments if your income changes mid-year
If your income is higher or lower than you predicted when you made your first payment, you can adjust your remaining quarterly payments. For example, if you had a strong first half of the year and expect to earn more than you initially thought, you can increase your third and fourth quarter payments to avoid underpayment penalties.
Conversely, if your income drops unexpectedly, you can lower your remaining payments. The key is to recalculate based on your current best estimate and adjust the next payment accordingly. Keep records of your reasoning in case the IRS questions your payments later.
Some people use the annualized income method, which lets you pay different amounts each quarter based on your actual income in each period rather than spreading an annual estimate evenly. This works well if your income is seasonal or lumpy.
Tracking your estimated tax payments and getting a receipt
When you pay through IRS Direct Pay or EFTPS, you'll receive a confirmation number immediately. Save this number—it's your proof of payment. The IRS records your payment in its system, and it will appear on your account when you log into IRS.gov using your credentials.
If you mail a check, include your Social Security number, filing status, tax year, and the amount on the check itself. Mail it with Form 1040-ES to the address for your state. The IRS processes mailed payments more slowly, so allow extra time. You won't receive a receipt in the mail, but you can check your payment status on IRS.gov after a few weeks.
Keep copies of all confirmation numbers and receipts until you file your tax return. If a payment doesn't show up in the IRS system after a reasonable time, contact the IRS or the payment processor to trace it.
Frequently Asked Questions
Can I skip a quarter if I didn't earn much income that quarter?
You can't skip a payment, but you can pay a smaller amount if your income was lower. The IRS expects four payments per year if you owe estimated tax. If you pay nothing in a quarter when you should have paid something, you may face underpayment penalties even if your total annual payment is correct. Use the annualized income method if your earnings vary by quarter.
What if I miss a payment deadline?
Pay as soon as you realize you missed it. The IRS will charge interest and penalties on the late amount, but paying late is better than not paying at all. The longer you wait, the more interest accrues. If you missed multiple quarters, catch up on all of them.
Do I need to make estimated tax payments if I'm also an employee with a W-2 job?
Only if your non-withheld income (self-employment, rental, investment, etc.) is substantial enough that your total tax owed exceeds $1,000 after accounting for withholding from your job. You can also adjust your W-4 with your employer to increase withholding, which may reduce or eliminate the need for estimated payments.
What's the difference between estimated tax and self-employment tax?
Estimated tax is income tax you owe on your profit. Self-employment tax is Social Security and Medicare tax on your net self-employment income. If you're self-employed, you owe both, and both are included in your estimated tax payment calculation. Form 1040-ES walks you through calculating both.
Can I pay estimated taxes monthly instead of quarterly?
The IRS requires four payments per year on specific dates. You can't make monthly payments to the IRS directly. However, you can set aside money monthly and pay it all at once on the quarterly due date, or you can pay early if you want to reduce interest on an underpayment.
