The countdown begins! ⏲️
The Extended Due Date for Business tax returns is Tuesday, September 15th. If you own a business, file a Form 1065 (Partnership) or 1120-S (S-Corporation) based on a calendar year-end, and filed an extension back in March — you have 2 WEEKS to file your 2025 business returns timely. If you have not yet provided ATLAS with all the necessary information to complete your 2025 returns, please do so as soon as possible.
Don't get caught short - late returns are subject to penalties and interest from the IRS and state. 😯
