Amount You Owe: Federal Income Tax (2025 IRS Guide)

This guide covers “Amount You Owe” within federal income tax. The following material presents the IRS treatment of this topic, including the qualifications, exceptions, and examples in the source section. Read the rules alongside the facts of your own situation before deciding what to report, deduct, or document.

Adapted from Publication 17 (2025), Your Federal Income Tax, published by the Internal Revenue Service. This guide retains the source edition’s years, amounts, deadlines, and examples. It is guidance for that edition, not a statement that the same figures apply to every tax year.

Context for these rules

This section explains how to get ready to complete your tax return and when to report your income and expenses. It also explains how to complete certain sections of the form.

Amount You Owe

When you complete your return, you will determine if you have paid the full amount of tax that you owe. If you owe additional tax, you should pay it with your return.

.You don’t have to pay if the amount you owe is under $1..

If the IRS figures your tax for you, you will receive a bill for any tax that is due. You should pay this bill within 30 days (or by the due date of your return, if later). See Tax Figured by IRS in chapter 13.

.If you don’t pay your tax when due, you may have to pay a failure-to-pay penalty. See Penalties, later. For more information about your balance due, see Pub. 594. .

.If the amount you owe for 2025 is large, you may want to increase the amount of income tax withheld from your pay or make estimated tax payments for 2026. See chapter 4 for more information..

How To Pay

You can pay online, by phone, by mobile device, in cash, or by check or money order. Don’t include any estimated tax payment for 2026 in this payment. Instead, make the estimated tax payment separately.

Insufficient funds.

The penalty for making a payment to the IRS that was dishonored is $25 or 2% of the dishonored payment amount, whichever is more. However, if the dishonored payment amount is less than $25, the penalty equals the amount paid. This penalty applies to all acceptable forms of payment if the IRS doesn’t receive the funds.

Pay online.

Paying online is convenient and secure and helps make sure we get your payments on time.

You can pay online with a direct transfer from your bank account using IRS Direct Pay or the Electronic Federal Tax Payment System (EFTPS), or by debit or credit card.

Estimated tax payments.

Don’t include any 2026 estimated tax payment in the payment for your 2025 income tax return. See chapter 4 for information on how to pay estimated tax.

Interest

Interest is charged on tax you don’t pay by the due date of your return. Interest is charged even if you get an extension of time for filing.

.If the IRS figures your tax for you, to avoid interest for late payment, you must pay the bill by the date specified on the bill or by the due date of your return, whichever is later. For information, see Tax Figured by IRS in chapter 13. .

Interest on penalties.

Interest is charged on the failure-to-file penalty, the accuracy-related penalty, and the fraud penalty from the due date of the return (including extensions) to the date of payment. Interest on other penalties starts on the date of notice and demand, but isn’t charged on penalties paid within 21 calendar days from the date of the notice (or within 10 business days if the notice is for $100,000 or more).

Interest due to IRS error or delay.

All or part of any interest you were charged can be forgiven if the interest is due to an unreasonable error or delay by an officer or employee of the IRS in performing a ministerial or managerial act.

A ministerial act is a procedural or mechanical act that occurs during the processing of your case. A managerial act includes personnel transfers and extended personnel training. A decision concerning the proper application of federal tax law isn’t a ministerial or managerial act.

The interest can be forgiven only if you aren’t responsible in any important way for the error or delay and the IRS has notified you in writing of the deficiency or payment. For more information, see Pub. 556.

Interest and certain penalties may also be suspended for a limited period if you filed your return by the due date (including extensions) and the IRS doesn’t provide you with a notice specifically stating your liability and the basis for it before the close of the 36-month period beginning on the later of:

• The date the return is filed, or

• The due date of the return without regard to extensions.

For more information, see Pub. 556.

Installment Agreement

If you can’t pay the full amount due with your return, you can ask to make monthly installment payments for the full or a partial amount. However, you will be charged interest and may be charged a late payment penalty on the tax not paid by the date your return is due, even if your request to pay in installments is granted. If your request is granted, you must also pay a fee. To limit the interest and penalty charges, pay as much of the tax as possible with your return. But before requesting an installment agreement, you should consider other less costly alternatives, such as a bank loan or credit card payment.

To apply for an installment agreement online, go to IRS.gov/OPA. You can also use Form 9465.

In addition to paying by check or money order, you can use a credit or debit card or direct payment from your bank account to make installment agreement payments. See How To Pay, earlier.

Using the guidance

Keep the documents that establish the dates, amounts, and circumstances described above. References to other chapters, forms, worksheets, or earlier and later sections refer to the linked IRS publication. Check the full publication and its updates before relying on a rule for a different tax year or a situation not addressed here.
