With the start of the 2026 Tax Season, one of the main issues we see every year relates to filing deadlines and the improper use of extensions. Requesting an extension does not change the amount of tax due; it only extends the filing deadline. Confusing these concepts often leads to unnecessary interest and penalties.

Some entities are due on March 16, while others are due on April 15. In addition, filing an extension does not mean the IRS will delay the payment if tax is owed. For this reason, before requesting an extension, it is essential to properly estimate the tax liability and coordinate both the filing and the payment.

As a FINANCERS client, we take care of determining your applicable deadlines, correctly managing extensions, and coordinating the entire process so the Tax Season does not become a problem. Feel free to reach out to us.
