If you own a home in Northwest Indiana, property taxes are likely one of your biggest ongoing expenses. And in 2026, the rules changed. Indiana passed new legislation that reshapes how property taxes are calculated across the state, including right here in Lake County, Porter County, and the surrounding region.
Whether you are current on your taxes or struggling to keep up, understanding what changed and what it means for your situation is important. This post breaks it down in plain language.
What Changed With Indiana Property Taxes in 2026
The new law gradually shifts Indiana's property tax relief system away from a flat dollar deduction toward a larger percentage-based deduction. In practical terms, this means a larger share of your home's assessed value is protected from property taxes over time, but the transition happens slowly, running through 2031.
Here is the key timeline to understand:
- The 2026 property tax bills you paid this spring covered your 2025 assessed values. The new law did not affect those bills.
- The first time you will see the new changes is on your 2027 bill, which covers 2026 assessed values.
- Most homeowners do not need to apply for the new credit. If your homestead deduction is already on file with your county auditor, the credit applies automatically.
💡 Important: If you bought your home in 2025 or 2026, recently refinanced, or transferred the property into a trust, verify your homestead deduction is on file with your county auditor. If it is missing, the credit will not appear on your 2027 bill.
What This Means for Lake County and Porter County Homeowners
Property tax rates in Lake County and Porter County have historically been among the higher rates in Indiana, which makes these changes meaningful for local homeowners. If your homestead deduction is properly filed, you should see gradually increasing relief on your annual bill as the percentage-based system phases in over the next several years.
For homeowners who are current on taxes and plan to stay in their home, this is largely good news over the long run. The transition may feel slow, but the direction is toward lower effective tax burdens for owner-occupied homes.
What If You Are Already Behind on Property Taxes
This is where things get more urgent. If you have fallen behind on property taxes in Lake County or Porter County, the new law does not erase what you owe. Back taxes, penalties, and interest continue to accumulate regardless of the new credits coming down the road.
Indiana gives counties the ability to pursue a tax sale on properties with delinquent taxes. Once a property enters the tax sale process, options narrow quickly and costs increase significantly.
If you are behind on property taxes, here are the paths most homeowners consider:
- Payment plan through the county treasurer: Lake County and Porter County both offer payment agreements for delinquent taxes. Contact your county treasurer's office directly to ask about eligibility.
- Sell the property: If the tax debt is significant and the property no longer makes financial sense to hold, selling, including a cash sale, can clear the debt and put money back in your pocket rather than losing the property to a tax sale.
- Refinance to pull equity: If you have equity in the home and good enough credit to refinance, you may be able to roll the back taxes into a new loan. This works best when the debt is manageable and you intend to stay in the property long term.
