What penalties or fees may apply if I miss the tax deadline?

Asked 2 years ago
When an individual or business fails to meet the tax deadline set by the Michigan Department of Treasury, several penalties and fees may come into play. The specific penalties can vary based on the type of tax and the duration of the delay. First, there is typically a late filing penalty, which is assessed on returns that are not submitted by the due date. This penalty can be a percentage of the unpaid tax amount and increases the longer the return remains unfiled. Additionally, if taxes owed are not paid by the deadline, a separate late payment penalty may be applicable. This penalty, too, is usually calculated as a percentage of the unpaid tax. Furthermore, interest accrues on unpaid taxes beginning after the deadline passes. The rate of interest is determined by the state and may change periodically. It is important to note that the Michigan Department of Treasury may impose additional consequences for more serious infractions, such as failure to file altogether or repeatedly failing to meet deadlines. The best practice is to check the official Michigan Department of Treasury website for the most current information, as well as specific guidelines regarding penalties, interest rates, and payment regulations. This resource is invaluable for anyone seeking clarity on tax responsibilities and potential consequences for noncompliance.
