Frequently asked questions

Does interest accrue on the money I owe?

Yes. Interest begins to accrue on the unpaid deposit amount from the day the deposit was due until the day we receive the deposit in full. Interest will begin to accrue on the penalty if you don’t pay the penalty amount within 10 days of the date of the notice.

Will I receive more than one failure-to-deposit penalty?

Maybe. When an employer fails to make a proper tax deposit, even if the failure is due to an error, we assess a 10% failure-to-deposit penalty. You may or may not have received notice of the 10% penalty before receiving this notice. If you think the penalty is an error or you believe you have reasonable cause for not making the proper tax deposit, you can ask us to remove the penalty. The penalty notice will explain your right to appeal. If you pay the unpaid tax (deposit) by the payment due date on your notice, we won’t assess any additional penalties on the amount you owe. If you don’t pay the total tax due by the notice due date, we will assess an additional 5% failure-to-pay penalty on top of the 10% failure-to-deposit penalty.
