A tax payment is money you send to the IRS or your state tax authority before you file your return, to cover the income tax you expect to owe

Most people have taxes taken out of their paychecks automatically through withholding. But if you're self-employed, have investment income, receive a pension, or earn money that isn't subject to withholding, you may need to send the IRS money on your own schedule. That's a tax payment. You can also make a tax payment if you want to pay down what you owe before filing your return, or if you received a notice from the IRS telling you to pay.

Tax payments are different from a tax refund. A payment is money you send in; a refund is money the government sends back to you after you file. Some people make payments throughout the year to avoid owing a large amount when they file. Others make a single payment when they file their return. The IRS accepts payments by mail, phone, online through its official website, or through a third-party payment processor.

Key Takeaways

  • A tax payment is money you send to the IRS or state tax authority to cover income tax you owe, separate from any withholding your employer may already be taking.
  • Self-employed people, contractors, and those with investment income often make quarterly estimated tax payments to avoid a large bill at tax time.
  • You can pay the IRS directly through IRS.gov, by phone, by mail, or through an approved payment processor, and each method has different fees and processing times.
  • Making a tax payment does not reduce your tax bill itself — it only pays down what you owe, and you still file a return to report your actual income and calculate your final tax.

When you need to make a tax payment

You need to make a tax payment if your employer is not withholding enough tax from your paycheck to cover what you'll owe. This happens most often if you're self-employed or run a business, because no withholding happens automatically. The IRS expects you to send in estimated tax payments four times a year — usually in April, June, September, and January — if you expect to owe $1,000 or more when you file.

You also make a tax payment if you receive income that has no withholding attached: rental income, investment gains, prize money, or income from a side job paid in cash or as a 1099 form. Retirees who receive a pension or Social Security may need to make payments if they didn't request enough withholding when they set up their pension. And if the IRS sends you a notice saying you owe money from a previous year, you can pay that amount before or when you file your next return.

Some people make a tax payment simply to reduce the amount they'll owe at tax time. If you know you'll have a large bill, paying part of it during the year means you won't face as big a balance due when you file.

How to calculate what to pay

If you're self-employed or have income without withholding, you can estimate your tax using IRS Form 1040-ES. This form walks you through your expected income, deductions, and credits for the year, then tells you what your quarterly payment should be. You can download it free from IRS.gov or ask a tax preparer to help you calculate it.

The calculation depends on your total expected income, your filing status, the number of dependents you claim, and any deductions or credits you expect to take. If your income varies month to month, you can adjust your quarterly payments as the year goes on — you don't have to pay the same amount each quarter. If you pay too much, you'll receive a refund when you file. If you pay too little, you'll owe the difference plus interest and possibly a penalty.

If you're unsure what to pay, a tax professional can calculate it for you. Many charge a flat fee for this service, and it may save you from underpaying and facing penalties later.

Payment methods and where to send money

The IRS offers several ways to pay. The fastest and most direct is through IRS Direct Pay on IRS.gov, which is free and lets you schedule a payment for a future date. You'll need your Social Security number, date of birth, and bank account information. The payment usually posts within one business day.

You can also pay by credit card or debit card through an approved payment processor. The IRS does not charge a fee, but the processor does — typically 1.87% to 2.35% of the amount you pay. Common processors include PayPal, Stripe, and Square. If you pay by phone, call the IRS at 1-800-829-1040 and speak to a representative who can take your payment information over the phone.

For mailed payments, send a check or money order to the IRS address listed in the Form 1040-ES instructions — the address varies by state. Write your Social Security number, tax year, and form type on the check. Mail payments take longer to process and may take two to three weeks to show up in your IRS account.

What happens after you make a payment

Once the IRS receives your payment, it's credited to your tax account. You can check the status of your payment on IRS.gov using the Where's My Payment tool, which updates every 24 hours. If you paid by direct debit from your bank, the money leaves your account on the date you scheduled. If you paid by check or mail, allow two to three weeks for processing.

Making a tax payment does not file your tax return or reduce your tax bill. You still need to file a return by April 15 (or the next business day if April 15 falls on a weekend or holiday) to report your actual income and calculate your final tax. When you file, the IRS will compare what you paid during the year to what you actually owe. If you paid more than you owe, you'll receive a refund. If you paid less, you'll owe the difference.

If you make a payment and then realize you overpaid, you can request a refund or ask the IRS to apply the overpayment to next year's tax bill. You can make this request when you file your return, or you can call the IRS to request it sooner.

Penalties and interest if you underpay

If you don't pay enough in estimated taxes during the year, the IRS may charge you underpayment penalties and interest on the amount you owe. The penalty is calculated based on how much you underpaid and for how long. Interest accrues daily from the due date of each quarterly payment until you pay the full amount.

You can avoid the penalty if you pay at least 90% of your current year's tax or 100% of your previous year's tax (110% if your previous year's adjusted gross income was over $150,000). If you have a large change in income partway through the year, you can adjust your remaining quarterly payments to catch up, and the IRS may waive the penalty for earlier quarters if you can show the underpayment was due to circumstances beyond your control.

If you receive a notice from the IRS about underpayment penalties, read it carefully. It will explain how much you owe and when to pay. You can dispute the penalty if you believe it was calculated incorrectly, but you must respond to the notice within the deadline given.

State tax payments

Most states that have an income tax also require estimated tax payments if you have income without withholding. The rules and payment schedules vary by state. Some states follow the same quarterly schedule as the federal government; others have different due dates. Some states allow you to pay online through their tax authority website; others require mailed checks.

If you live in a state with no income tax, you won't make state estimated tax payments. If you work in one state but live in another, you may need to make payments to both. Check your state's tax authority website for the specific rules and payment methods for your state.

Frequently Asked Questions

Can I make a tax payment without filing a return?

Yes. You can send money to the IRS at any time, and it will be credited to your account. However, you still must file a return by April 15 to report your income and claim any refunds or deductions you're due. The payment alone does not satisfy your filing requirement.

What if I can't pay the full amount I owe?

You can pay part of what you owe now and set up a payment plan for the rest. The IRS offers short-term plans (120 days or less) at no cost and long-term installment agreements that charge a setup fee and monthly interest. You can set up a plan online through IRS.gov or by calling the IRS.

Do I get a receipt when I make a tax payment?

Yes. If you pay online through IRS Direct Pay or a payment processor, you'll receive a confirmation number immediately. Keep this number for your records. If you mail a check, the IRS will send you a notice when the payment is received and posted to your account.

Can I make a tax payment for someone else?

You can send money to the IRS on behalf of someone else, but the payment must include that person's Social Security number so it's credited to the correct account. The IRS will not accept a payment without a valid taxpayer identification number to match it to.

What's the difference between a tax payment and a refund?

A tax payment is money you send to the IRS to cover tax you owe. A refund is money the IRS sends back to you after you file your return, if you paid more in taxes than you actually owed. Payments reduce what you owe; refunds are money returned to you.
