March 15 is the tax-filing due date for calendar year S-corporations and partnerships. While this filing deadline does not require making a tax payment, missing the due date could cost you a hefty penalty.
The penalty is calculated based on each partial month the tax return is late multiplied by each shareholder or partner. So a tax return filed 17 days late with no tax due could cost a married couple who jointly own a small S-corporation $800 in penalties!*
Here are some ideas to help you avoid penalties:
File on Time
If you are a partner or shareholder of an S-corporation or partnership, file your company's tax return on or before March 15. In addition to the penalties, filing late shortens the time you have to file your individual tax return and pay the taxes due by April 15.
Consider an Extension
Depending on the degree to which a state incorporates recent federal tax changes, you could see a big tax surprise on your state tax return. As a result, the nonprofit Tax Foundation is anticipating that many taxpayers will experience an increase in state taxes for 2018.
Your Personal Tax Return May be Delayed
Do not file your Form 1040 tax return until you receive all your K-1s from each of your S-corporation and partnership business activities. Be prepared — If the business files an extension, it's possible you may need to extend your personal tax return while you wait for the K-1. This does not extend the due date for paying taxes owed.
Challenge the Penalty
While you may not be successful, it doesn't hurt to try to abate the penalty. This is especially true if you file and pay your personal taxes on time. Kindly remind the US Treasury it is still receiving the taxes owed to them in a timely manner.
If you haven't filed your S-corporation or partnership return for 2018, there's still time to get it done or file an extension. Please call if you need assistance.
