Need more time to file taxes?

This year’s tax-filing deadline is April 18. Taxpayers needing more time to file their taxes can get an automatic six-month extension from the IRS.

Below are five things to know about filing an extension:

Use IRS Free File to file an extension. IRS Free File allows taxpayers to prepare and e-file their taxes for free. It can also be used to e-file a free extension to file request. Midnight April 18 is the deadline for receipt of an e-filed extension request. Free File is accessible for tax return preparation and e-filing through Oct. 17. It is only available through IRS.gov.

Use Form 4868. Fill out a request for an extension using Form 4868, Application for Automatic Extension of Time to File U.S. Individual Income Tax Return. The deadline for mailing the form to the IRS is April 18. Form 4868 is available on IRS.gov/forms.

More time to file is not more time to pay. Requesting an extension to file provides taxpayers an additional six months (until Oct. 16) to prepare and file taxes. However, it does not provide additional time to pay taxes owed. Taxpayers should estimate and pay any owed taxes by April 18 to avoid a potential late-filing penalty. To avoid penalties and interest, pay the full amount owed by the original due date.

Use electronic payment options to get an automatic extension. An extension of time to file will automatically process when taxpayers pay all or part of their taxes electronically by April 18. There is no need to file a paper or electronic Form 4868 when making a payment with IRS Direct Pay, the Electronic Federal Tax Payment System (EFTPS) or by debit or credit card. Select “Form 4868” as the payment type. Keep the confirmation as proof of payment.

The IRS can help. The IRS offers payment options for taxpayers who can’t pay all the tax they owe. In most cases, they can apply for an installment agreement with the Online Payment Agreement application on IRS.gov. They may also file Form 9465, Installment Agreement Request. If a taxpayer can’t make payments because of financial hardship, the IRS will work with them.

Taxpayers should keep a copy of their tax return. Beginning in 2017, taxpayers using a software product for the first time may need their Adjusted Gross Income (AGI) amount from their prior-year tax return to verify their identity.
