Income Tax

General Information

The Income Tax Office provides the service of collection, audit, and enforcement of the 2.25% income tax for the City of Miamisburg as well as Austin Center Joint Economic Development District (JEDD) and the Miami Crossing JEDD.

Calendar year end tax returns are due the same date as federal tax returns. Taxpayers can also request a federal filing extension to October 15th that will be honored by the City of Miamisburg. This will be an extension of time to file, not an extension to pay.

Residents of the City of Miamisburg are allowed full credit up to (2.25%) for taxes due and paid to other cities on the same income taxed by Miamisburg.

The interest rate is calculated based on the federal short-term rate plus 5%. The rates are as follows:

  • Calendar year 2021: 5% per year or 0.42% per month
  • Calendar year 2022: 5% per year or 0.42% per month
  • Calendar year 2023: 7% per year or 0.58% per month
