April 15 is the annual deadline for most people to file their federal income tax return and pay any taxes they owe. If, for whatever reason, you missed the deadline you may be assessed penalties for both failing to file a tax return and for failing to pay taxes they owe by the deadline. Here are eight important facts every taxpayer should know about penalties for filing or paying late:

1. Two penalties may apply. A failure-to-file penalty may apply if you did not file by the tax filing deadline. A failure-to-pay penalty may apply if you did not pay all of the taxes you owe by the tax filing deadline.

2. File even if you can’t pay. The failure-to-file penalty is generally more than the failure-to-pay penalty. You should file your tax return on time each year, even if you’re not able to pay all the taxes you owe by the due date. You can reduce additional interest and penalties by paying as much as you can with your tax return. You should explore other payment options such as getting a loan or making an installment agreement to make payments. Call if you need help figuring out how to pay what you owe.

3. Penalty for late filing. The penalty for filing late is normally 5 percent of the unpaid taxes for each month or part of a month that a tax return is late. That penalty starts accruing the day after the tax filing due date and will not exceed 25 percent of your unpaid taxes.

4. Penalty for late payment. If you do not pay your taxes by the tax deadline, you normally will face a failure-to-pay penalty of 1/2 of 1 percent of your unpaid taxes. That penalty applies for each month or part of a month after the due date and starts accruing the day after the tax-filing due date.

5. Late payment penalty may not apply. If you timely requested an extension of time to file your individual income tax return and paid at least 90 percent of the taxes you owe with your request, you may not face a failure-to-pay penalty. However, you must pay any remaining balance by the extended due date.

6. Combined penalty per month. If both the 5 percent failure-to-file penalty and the 1/2 percent failure-to-pay penalties apply in any month, the maximum penalty that you’ll pay for both is 5 percent.

7. Minimum late filing penalty. If you file your return more than 60 days after the due date or extended due date, the minimum penalty is the smaller of $135 or 100 percent of the unpaid tax.

8. No penalty if reasonable cause. You will not have to pay a late-filing or late-payment penalty if you can show reasonable cause for not filing or paying on time.

Special penalty relief may apply to taxpayers under certain conditions such as taxpayers affected by natural disasters. If you think this applies to you, don’t hesitate to connect with me on TaxConnections for more information.
