Mahoning County, Ohio Property Tax Due Dates and Penalties (2026)

Posted On February 4, 2026February 4, 2026

In Mahoning County, Ohio, property taxes are paid in two instalments each year. For 2026 (tax year 2025), the first half is usually due in March, and the second half is due in July or early August. If taxes are not paid by the due date, a 10% late penalty is added immediately, even if you did not receive the tax bill. Paying on time is important to avoid penalties, interest, and possible delinquency actions.

Property Tax Due Dates and Penalties Explained

Property tax due dates and penalties can be confusing, but they follow a simple rule. Property taxes are due on specific dates set by the county, usually in two installments each year. If payment is not made by the deadline, a late penalty (often 10%) is added automatically, with no grace period. Continued non-payment may lead to interest charges, delinquent status, or tax lien actions, so paying before the due date helps avoid extra costs and legal issues.

Key Points:

• Property taxes are paid in two installments each year.
• Due dates are set by the county and must be followed strictly.
• A 10% late penalty is added immediately after the due date.
• Not receiving a tax bill does not remove responsibility to pay on time.
• Ongoing non-payment can result in interest, delinquency, or tax liens.

Understanding Property Tax in Mahoning County

In Mahoning County, property tax is based on your property’s value and is paid in two yearly instalments. Late payments receive a 10% penalty, so paying on time is important.

Who pays property tax?

• Property owners are responsible for paying property tax.
• If there’s a mortgage, the lender may pay taxes through an escrow account.
• Businesses or organizations that own property also must pay property tax.
• Renters do not pay property tax directly, but landlords may include it in rent.

How it works:

1. The County Auditor determines your property’s assessed value based on market value.
2. Local tax rates (mills) are applied to the assessed value to calculate your tax bill.
3. The Treasurer’s Office sends tax bills, usually in two installments per year.
4. You pay the taxes by the due dates (online, by mail, or in person).
5. Late payments incur penalties (e.g., 10%) and may lead to interest or delinquency actions.
6. Funds collected are used to support schools, local government, and public services.

Tip: Keep your property assessment up to date and verify your tax bill every year.
