Important 2025 Tax Deadlines

2025 and all of its tax deadlines are upon us!

Below is a quick guide of the most important dates to keep in mind this calendar year.

• January 15th: due date to pay 4th quarter estimated taxes.

• September 30th: due date for extended trust returns.

• October 15th: due date for extended individual tax returns and C-Corp returns.

• November 17th: due date to file extended nonprofit returns.

A reminder as regards the April 15th deadline: an extension is an extension to file, not an extension to pay.

If you file an extension and still owe money you will be assessed the failure-to-pay penalty of 0.5% per month on the balance. This is a huge improvement over the 5% per month failure-to-file penalty (capping at 25%) – so by all means file an extension (or get us to file one for you) if you need one.

In addition, filing an extension for corporate entities (S-Corps, most multi-member LLCs, LLCs electing S-Corp status) is very important. The failure-to-file penalty for those entity returns is $245 per officer per month the return is late (capping at 12 months) – even if there was no activity. Since C-Corporations (Form 1120) pay tax at the entity level, their penalties are based on the percentage of tax owed. The penalty is 5% per month (up to a maximum of 25% of the tax owed).
