Indiana property tax payments are due twice a year, on May 10 and November 10

Indiana splits property tax bills into two installments. The first half is due May 10, and the second half is due November 10. If either date falls on a weekend or holiday, the important date moves to the next business day. You will receive a bill in the mail before each due date, though the exact timing varies by county.

The bill itself shows the property address, the assessed value, the tax amount owed, and where to send payment. Most counties accept checks, money orders, and online payments through their treasurer's office website. Some also accept credit cards, though a processing fee may explore. Payment by mail should arrive several days before the important date to may support it is received on time.

Key Takeaways

  • Property tax bills in Indiana are due twice yearly: May 10 for the first installment and November 10 for the second.
  • Your county treasurer's office processes payments and can tell you the exact due date if it falls on a weekend or holiday.
  • Late payments trigger a penalty of 10 percent of the unpaid amount, plus interest that accrues monthly.
  • If you do not pay property taxes for two years, the county can sell your property at a tax sale.
  • Homeowners over 65 and disabled homeowners may reduce their tax burden through the Homestead Property Tax Deduction.

Where to send your payment

Each county in Indiana has a treasurer's office that handles property tax payments. You can find your county treasurer's mailing address and payment options on your property tax bill or on your county's official website. The bill itself lists where to send checks or money orders.

Many counties now offer online payment through their treasurer's website, which allows you to pay by bank transfer or debit card. Some treasurers also accept payments in person at their office during business hours. If you pay online, confirm the payment went through before the due date—do not rely on the date you submitted it, since processing can take a few days.

What happens if you miss the important date

A 10 percent penalty is added to any unpaid property tax balance after the due date passes. Interest also begins to accrue at a rate set by Indiana law, compounding monthly on the unpaid amount plus the penalty. For example, if your bill is $1,000 and you pay 30 days late, you owe $1,000 plus $100 (the 10 percent penalty) plus interest calculated from the due date.

If property taxes remain unpaid for two years, the county treasurer can place your property in a tax sale. This means the county sells your property rights to recover the unpaid taxes. You may have a chance to reclaim the property by paying the full amount owed plus costs, but the window to do so is limited and varies by county. Avoiding late payment is far simpler than dealing with a tax sale later.

Payment plans and hardship options

Indiana does not have a statewide property tax payment plan program, but some counties offer arrangements for taxpayers facing hardship. Contact your county treasurer's office directly to ask whether they can work with you on a payment schedule. Treasurers have discretion to negotiate in some cases, especially if you are current on one installment but struggling with the other.

If you own a home and are over 65 or disabled, you may reduce your property tax bill through the Homestead Property Tax Deduction. This program caps the amount of property tax you pay based on your income. You must file a claim with your county assessor's office, and the deduction applies to future tax bills once approved. This is separate from the payment important date but can lower what you owe overall.

How property tax amounts are set

Your property tax bill is calculated by multiplying your property's assessed value by the tax rate set by your county and local taxing units. The assessed value is determined by your county assessor and is supposed to reflect the market value of your home. The tax rate varies by location because different school districts, fire departments, and municipalities levy their own taxes on the same property.

You can challenge your assessed value if you believe it is too high. File a formal objection with your county assessor's office, usually within 45 days of receiving your assessment notice. The assessor will review your claim and may adjust the value. If you disagree with their decision, you can appeal to the county property tax assessment board of appeals. This process takes time but can lower your bill if successful.

Setting up automatic payments

Some county treasurers allow you to set up automatic payments for both installments each year. This removes the risk of forgetting a important date and avoids late penalties. Ask your county treasurer whether they offer automatic payment through bank draft or online bill pay. If they do, you will need to provide your bank account information and authorize the county to withdraw funds on or before each due date.

Even with automatic payment, review your bill when it arrives to make sure the amount is correct. If your assessed value changes or a special assessment is added, the automatic payment amount may not cover the full bill. Catching errors early gives you time to adjust the payment or file an objection before the important date.

Frequently Asked Questions

Can I pay my property taxes online in Indiana?

Most Indiana counties accept online payments through their treasurer's website. Check your county treasurer's site or your property tax bill for the payment portal. Some counties charge a small processing fee for online or credit card payments, so confirm the total cost before submitting.

What if I own property in more than one Indiana county?

Each county sends separate bills and has its own due dates and payment methods. You must pay each bill to the correct county treasurer by May 10 and November 10. Set reminders for each property to avoid missing a important date and triggering penalties on multiple bills.

Do I have to pay property taxes if I have a mortgage?

Yes. Even if your lender pays property taxes through an escrow account, you are legally responsible for the bill. If your lender fails to pay, the county can still place a lien on your home or sell it at tax sale. Confirm your lender is paying on time by reviewing your annual escrow statement.

Can I deduct Indiana property taxes on my federal income tax return?

You may deduct state and local property taxes on your federal return, but the total deduction for all state and local taxes is capped at $10,000 per year. Consult a tax professional to determine whether itemizing deductions benefits you more than taking the standard deduction.

What is a tax sale, and can I stop it?

A tax sale occurs when unpaid property taxes are two years overdue. The county sells your property rights to recover the debt. You can stop the sale by paying the full amount owed plus costs and interest before the sale date. Once the sale happens, you have a limited time to reclaim the property by paying the buyer, but this window is short and the cost is higher.
