September 15 is the fourth or fifth most important tax filing deadline for accountants. It’s the deadline for filing partnerships and S-corporations that got an extension from their earlier dates. Lots of fun for everyone involved, let us tell you.
If you have a calendar year S-Corporation that didn’t file on March 15th or a partnership that didn’t file on April 15, your taxes are NOW DUE.
Talk to your accountant if you have questions, and make sure all your paperwork is prepared.
