The first big tax filing deadline of the year is upon us: The deadline for calendar year corporations (both C Corporations and S Corporations) to file their tax returns is Thursday, March 15th. What if you have a corporation and just now realize you need to file your return? That’s simple: File an extension.
You can download the extension form here; you can get the instructions here. Just make sure you mail the form using certified mail, return receipt requested. If you use a tax professional, he or she can likely file your extension electronically.
S Corporations generally don’t owe tax. However, C Corporations may owe tax. If you’re filing the extension for a C Corporation, make an estimate of the tax you owe and set it with the extension.
The next deadline, April 17th, is for individuals, partnerships, and fiduciary returns (trusts and estates).
