Deadline for individuals who filled an extension.

The 2025 tax season is here, and it’s time to get prepared. Staying on top of key deadlines will help you avoid last-minute stress and ensure your filings are accurate and on time.

March 15 is the deadline to file 2024 federal business tax returns for S corporations and partnerships, or to request an extension. To ensure on-time filing, we recommend dropping off your business tax information at least 2–3 weeks before this date.

Today is the final day to file your 2024 S corporation or partnership tax return, or to submit an extension request. All required tax documents must be filed by the end of the day to avoid late penalties.

All drop-offs will be processed in the order they are received. If we are unable to complete your return by the deadline, an extension will be filed on your behalf.

April 15 is the deadline to file your 2025 federal and Colorado state individual income tax returns or request an extension. Make sure to submit your return or extension by this date to avoid late filing penalties and interest.

Reminder, an extension gives you more time to file — but not more time to pay.

If you filed for an extension, October 15 is the final deadline to submit your 2024 federal and Colorado state individual income tax returns. Returns must be filed by this date to avoid further penalties. Remember, any taxes owed should have been paid by April 15 — this deadline is only for filing your completed return.
