October 15 Is the Deadline to File Under a 6-month Extension

The October 15 deadline applies to taxpayers who requested a 6-month extension to file their 2023 tax return. The IRS encourages filers to submit their returns as soon as possible to avoid penalties. If you are owed a refund, filing sooner means receiving your money faster. If you owe taxes, remember that the extension only applies to filing the return—not to paying taxes owed. Interest charges accrue daily on unpaid balances after the April deadline. If you cannot pay in full, you should still file promptly to minimize penalties.
