If you plan to sell your home this year, understanding Indiana property tax deadlines can save you money, stress, and a surprise at the closing table. Timing matters more here than in many other states.
Indiana collects property taxes a year behind. That means when you sell, you may still owe taxes for time you already lived in the home, even if every bill so far is paid.
Missing a due date can add penalties, delay your closing, or even put your property at risk. Knowing the calendar helps you plan your sale with confidence.
This guide covers how Indiana property taxes work, the key dates, what happens if you miss one, how taxes are split at closing, and a simple checklist for sellers.
How Indiana Property Taxes Work
Before you can make sense of Indiana property tax deadlines, you need to understand one key idea: Indiana property taxes are paid in arrears.
Paid One Year Behind
Your home is assessed as of January 1 each year. The taxes for that year are billed and paid the following year. Locals often call this “2026 pay 2027.”
So the bills you pay in 2026 actually cover the 2025 tax year. If you sell in 2026, you are also building up 2026 taxes that will not be billed until 2027.
Who Sets the Bill
#1 County assessor. Determines your home’s assessed value each year and mails a notice of assessment.
#2 County auditor. Applies deductions like the homestead deduction and calculates the tax rate for your area.
#3 County treasurer. Mails the tax bill, collects payments, and handles delinquent accounts.
Property Tax Caps
Indiana’s constitution caps property taxes at 1% of assessed value for owner-occupied homes, 2% for rental homes and farmland, and 3% for other property. Some voter-approved levies can exceed these caps.
Key Indiana Property Tax Deadlines Every Seller Should Know
Mark these dates on your calendar. Together, these Indiana property tax deadlines shape what you owe before, during, and after your sale.
January 1: Assessment Date
Your home’s value and your eligibility for most deductions are set as of January 1. Whoever owns and lives in the home on that date matters for that tax year.
Spring: Notice of Assessment
Counties mail assessment notices in the spring. Read yours carefully, since it shows the value your taxes will be based on.
Appeal Deadline
If you think your assessment is too high, you can file an appeal with the county. The deadline is generally June 15 if your notice was mailed before May 1, or 45 days after the notice date if mailed later.
May 10: First Installment Due
The spring installment is due May 10. If that date falls on a weekend or holiday, it moves to the next business day.
November 10: Second Installment Due
The fall installment is due November 10, with the same weekend rule. Many sellers forget this payment if they are in the middle of moving.
Deduction Filing Deadline
Applications for deductions like the homestead deduction are generally due in early to mid-January of the year after the assessment date. Check your county auditor’s current deadline, as it has changed in recent years.
What Happens If You Miss a Deadline
Ignoring Indiana property tax deadlines gets expensive quickly, and unpaid taxes become a lien on your home that must be cleared before any sale can close.
#1. Late penalty. A penalty of 5% generally applies if you pay within 30 days of the due date and have no other delinquent taxes. After that, the penalty usually rises to 10%.
#2. Growing delinquency. Unpaid installments keep adding penalties each time another installment is missed.
#3. Tax lien. Delinquent taxes attach to the property. Your title company will find them, and they will be paid from your sale proceeds.
#4. Tax sale. If taxes stay unpaid long enough, the county can offer the property at a tax sale. Owners have a limited redemption period to pay and keep the home.
#5. Closing delays. Large unpaid balances, especially with a pending tax sale, can slow down title work and push back your closing date.
If you are already behind, contact your county treasurer right away. Paying before you list keeps your sale clean and your buyer confident.
How Indiana Property Tax Deadlines Affect Your Closing
Because taxes run a year behind, Indiana sellers often hand buyers a larger tax credit at closing than sellers in other states. This is called a proration.
The idea is simple. You pay for the time you own the home. The buyer pays for the time after closing. The title company handles the math on your settlement statement.
A Simple Proration Example
Say your annual property tax bill is $2,400, paid in two $1,200 installments. You close on September 1, 2026, and already paid the May 2026 installment.
#1. November 2026 installment. This $1,200 bill covers the 2025 tax year, when you owned the home. You either pay it at closing or credit the buyer, who pays it later.
#2. 2026 taxes, January through August. These will not be billed until 2027. You owned the home for about eight months, so you credit the buyer roughly $1,600.
#3. Total seller credit. About $2,800 comes out of your proceeds, even though you never missed a payment.
Why Sellers Get Surprised
Many sellers think they are “paid up” because their last bill is paid. Understanding Indiana property tax deadlines shows why you still owe for taxes not yet billed.
Proration customs can vary by county and by contract. Your purchase agreement controls how taxes are split, so read that section carefully.
What Happens to Your Deductions When You Sell
Deductions lower your assessed value and your bill. When you sell, they do not automatically follow you or pass to the buyer, which ties directly into Indiana property tax deadlines.
Common Indiana Homeowner Deductions
#1 Homestead deduction. The main deduction for an owner-occupied primary residence. It also unlocks the 1% tax cap.
#2 Supplemental homestead deduction. An added percentage reduction applied automatically with the standard homestead deduction.
#3 Over-65 and disability deductions. Available to qualifying owners who meet age, income, or disability requirements.
#4 Veterans deductions. Available to qualifying disabled veterans and certain surviving spouses.
What Sellers Need to Do
Your deductions stay tied to the tax year they were approved for. Once you no longer own or live in the home, you are not eligible for future years.
If you buy a new Indiana home, file for the homestead deduction there right away. Your old deduction will not move with you.
Tell the county auditor promptly if you become ineligible. Claiming a deduction you no longer qualify for can lead to back taxes and penalties.
Recent Law Changes
Indiana passed major property tax changes in 2025 that phase in over several years, including new credits for homesteads. Ask your county auditor how they apply to your bill.
Property Tax Checklist Before You Sell
Use this checklist a few weeks before you list. It turns Indiana property tax deadlines from a source of stress into a simple part of your selling plan.
#1 Look up your tax account. Visit your county treasurer’s website and confirm every installment is paid and no penalties are pending.
#2 Note the next due date. If May 10 or November 10 falls before your closing, decide whether to pay it yourself or have it paid at closing.
#3 Review your deductions. Confirm which deductions are on your bill so you understand what the buyer will and will not inherit.
#4 Estimate your proration. Ask your title company for a rough tax proration figure early. It helps you calculate your true net proceeds.
#5 Check for special assessments. Some areas add sewer, drainage, or other charges to the tax bill. These may need to be settled before closing.
#6 Gather recent tax bills. Buyers and title companies often ask for the last one or two years of statements.
#7 Watch for appeals. If you appealed your assessment, tell the buyer and title company. A pending refund or adjustment should be addressed in the contract.
#8 Plan for your next home. If you are buying in Indiana, put the homestead deduction filing date on your calendar so you do not lose a year of savings.
Working through these steps early prevents last-minute surprises and keeps your closing on schedule.
Frequently Asked Questions
What are the main Indiana property tax deadlines?
The two payment deadlines are May 10 and November 10. If either falls on a weekend or holiday, payment is due the next business day.
Why do Indiana sellers pay taxes at closing if their bills are current?
Indiana bills taxes a year behind. At closing, sellers usually credit buyers for taxes that built up during their ownership but have not been billed yet.
Who pays the property tax bill due after closing?
Usually the buyer pays it, using the credit the seller gave at closing. Your purchase agreement and settlement statement spell out the details.
Does my homestead deduction transfer to the buyer?
No. The buyer must apply for their own homestead deduction if they will live in the home as their primary residence.
Can I sell my house if I owe back property taxes?
Yes. Delinquent taxes and penalties are typically paid from your proceeds at closing. Contact the county treasurer early to confirm the exact payoff.
What if the tax bill comes out higher than the estimate used at closing?
Prorations are usually based on the most recent bill and are final unless your contract says otherwise. Some buyers and sellers agree to adjust later.
Final Thoughts
Selling a home in Indiana means planning around a tax system that runs a year behind. Knowing Indiana property tax deadlines helps you avoid penalties and understand every number on your settlement statement.
Pay installments on time, check your account before listing, and ask your title company for a proration estimate early. Those three steps prevent most closing day surprises.
With the calendar on your side, you can focus on what matters most: getting a fair price and moving on to your next chapter.
