Credits when you work in another city
Many buyers work in one city and live in another. Miamisburg residents may claim credit for municipal taxes paid to another city on the same income, typically up to 2.25%. The net effect depends on both cities’ rates and the credit rules. Compare rates and review the city’s filing instructions, especially if your household has income in multiple municipalities.

JEDDs you may encounter
Miamisburg administers income tax for some nearby Joint Economic Development Districts, including Austin Center and Miami Crossing/Dayton Mall. These districts commonly levy 2.25% and share revenue per their agreements. If you rent, buy, or work in an apartment, office, or mixed‑use property inside a JEDD boundary, municipal or JEDD income taxes may apply to income generated there. Always confirm parcel‑level boundaries before you buy or sign a lease.

Filing, deadlines, and penalties
Deadlines and extensions
Calendar‑year returns are due the same day as your federal return. The city honors the federal extension to October 15 for filing, but you must pay by the normal due date to avoid interest and penalties.

Estimated payments
If you have income without employer withholding, such as self‑employment or certain investment income, you may need to make estimated municipal payments. The city’s guidance explains how non‑W‑2 income is handled and notes that the online filing tool is best for full‑year residents with only W‑2 income.
Penalties and interest
Municipal tax offices charge penalties for late filing or payment and assess interest on unpaid balances. Miamisburg identifies a 10% annual interest rate for 2024 to 2025 on its page, based on the federal short‑term rate plus five percentage points. Interest and penalties can add up quickly, so file and pay on time.

Refunds and adjustments
If you overpay, you can request a refund following the procedures in the city code. Employers also have reconciliation and liability rules where withholding was required but not performed.
