When Are Business Taxes Due?

If you're wondering when business taxes are due, they have due dates that can vary depending on the company type. Sole proprietorships, corporations, and partnerships tend to have different deadlines for filing tax returns. Due dates typically stay the same from year to year, but it is possible for them to change.

To avoid missing an important due date accidentally, it is important to check for important tax deadlines for your business every year. The Internal Revenue Service (IRS) could give you a penalty if you miss the time frames.

Tax returns start being processed by the IRS on January 23 and they accept paper-filed and electronically filed returns. The following are the various forms and their due dates which could change, so always check.

  • Businesses must send their employees W-2 forms or Form 1099's by February 1.

  • February 15 is the deadline for financial institutions to send Form 1099-B that relates to sales of mutual funds, stock, or bonds through a brokerage account, Form 1099-S that relates to real estate transaction, and Form 1099-MISC if the sender has to report payment in boxes 8 or 14.

  • February 28 is the deadline for paper versions of Form 1099. March 31 is the deadline for electronic forms.

  • For a business that has independent contractors as employees, you may file Form 1099-MISC with Box 7 for non-employee compensation empty.

  • Form 1120, 1120A (C-corporations) or 1120S (S Corporations) is due March 15. You should also use this date to file a tax extension if using Form 7004. Any taxes due should be getting paid by this date even if you did not file an extension. For business partnerships, you should Form 1065 by this date. For partnerships using Form 7004, tax extensions can get filed at this time as well.

  • Paper filing for businesses of Forms 1099 and 1096 have a deadline of February 28.

Tax extension requests are due by this date. However, any owed taxes are due at that time, regardless, if you filed for an extension.
