Filing Extensions

Form 4868 can be used to request an extension, but it must be filed before the tax day deadline. If granted, the taxpayer has until October 15th to file their taxes.

A filing extension does not grant an extension for payment. Late fees will be charged if tax payments are late.

How to File

Depending on the document, IRS forms can be filed electronically, by mail, by fax, or by a tax professional.

Electronic Filing

  • IRS Free File Guided Tax Preparation – Available for free to any taxpayers with an AGI (adjusted gross income — or your net taxable income minus eligible deductions) of less than $79,000.
  • Free File Fillable Forms – Available for all taxpayers. The taxpayer must use publications and must do the legwork to understand and fill out the forms.
  • Paid Software – Popular tax software providers like TurboTax, H&R Block and TaxAct guide taxpayers through tax forms and electronically file forms. These paid platforms range from free to $200+.

Mail Filing

IRS tax forms can be filed by mail. Taxpayers can obtain the necessary forms for filing, complete them, and mail them to the IRS address listed on the form. Some addresses may differ when a payment is or is not included.

Returns processed via mail can be delayed by weeks. The IRS notes on its website that taxpayers and tax professionals are encouraged to file returns electronically.
