Taxpayers should file their tax return by the deadline even if they cannot pay their full tax bill. Taxpayers who owe tax and don't file on time may be charged a failure-to-file penalty. This penalty is usually five percent of the tax owed for each month, or part of a month that the tax return is late, up to 25%.

If an individual taxpayer owes taxes, but can't pay in full by April 18, 2022, deadline, they should:

File their tax return or request an extension of time to file by the April 18 deadline.

• People who owe tax and do not file their return on time or request an extension may face a failure-to-file penalty for not filing on time.
• Taxpayers should remember that an extension of time to file is not an extension of time to pay. An extension gives taxpayers until October 17, 2022, to file their 2021 tax return, but taxes owed are still due April 18, 2022.

To get an extension to file, taxpayers must do one of the following:

• File Form 4868 through their tax professional, tax software, or using Free File on IRS.gov.
• Submit an electronic payment with Direct Pay, Electronic Federal Tax Payment System or by debit, credit card or digital wallet and select Form 4868 or extension as the payment type.

Pay as much as possible by the April 18 due date.

• Whether filing a return or requesting an extension, taxpayers must pay their tax bill in full by the April deadline to avoid interest and penalties.
• People who do not pay their taxes on time will face a failure-to-pay penalty.
• The IRS has options for taxpayers who can't afford to pay taxes they owe.

Set up a payment plan as soon as possible.

• Taxpayers who owe but cannot pay in full by April 18 don't have to wait for a tax bill to set up a payment plan.
• They can apply for a payment plan on IRS.gov.
• Taxpayers can also submit a payment plan request using Form 9465, Installment Agreement Request.

Interest is based on the amount of tax owed and for each day it's not paid in full. Interest rates are determined every three months and can vary, based on the type of tax; for example, individual or business-tax liabilities. More information is available on the Interest on Underpayments and Overpayments page of IRS.gov.
