As we move into the final days of the 2023 tax season, we’re continuing to complete returns as quickly as possible. For those returns that can’t be completed by April 18, an automatic extension (until October 16) will be filed, giving us time to achieve your best result!

The automatic extension provides additional time to file BUT payment is still due April 18. If you think you may owe, you can use links below to make 2022 extension payments. Electronic 1040 extensions will be transmitted on Sun, Apr 16. All clients not in "FINAL" status will be automatically extended.
