Almost everything written about Indiana's Senate Bill 1 talks about homeowners. New credits, a shrinking standard deduction, a bigger supplemental deduction. All of it aimed at owner-occupied homes.
Buried inside that same bill is a separate provision that actually applies to rental property, and it has gotten far less attention than it deserves.
We manage rentals across Westfield and the rest of Hamilton County, so we track exactly how new tax law affects investment property, not just primary residences. Here is what SB 1 actually does for landlords.
Key Takeaways
- Most of SB 1's headline provisions, the new homestead credit and expanded supplemental deduction, apply only to owner-occupied primary residences, not rental property.
- SB 1 also created a separate deduction for residential non-homestead properties subject to the 2 percent tax cap, which includes most rental homes.
- This rental property deduction starts at 6 percent of assessed value for 2025 and grows gradually to 33.4 percent by 2030.
- The deduction is expected to apply automatically in most cases, similar to the homestead credit, though it's worth confirming with your county auditor.
- SB 1 also requires a statewide property tax transparency portal, giving owners an easier way to compare their bill year over year.
What Most Coverage of SB 1 Gets Wrong for Landlords
Nearly every headline about Senate Bill 1 focuses on the new homestead tax credit, worth 10 percent of a homeowner's bill up to $300, and the shifting balance between the standard and supplemental homestead deductions. Both of these apply specifically to homestead property, meaning a home the owner occupies as their primary residence.
If you own a rental property, none of those headline provisions apply to you directly. That does not mean SB 1 ignored rental property entirely, though. It just means the relevant provision has gotten far less press.
The Deduction That Actually Applies to Rental Property
Buried in the same bill is a new deduction specifically for residential non-homestead properties subject to the 2 percent property tax cap, which is the category most rental homes fall into. This deduction begins at 6 percent of assessed value for the 2025 tax year and increases each year gradually, reaching 33.4 percent by 2030.
In plain terms, this means a growing share of your rental property's assessed value will be shielded from taxation over the next several years, similar in spirit to what homeowners are getting through the homestead deduction, just under a different mechanism.
How the Phase-In Actually Works
The deduction is modest in its first year at 6 percent of assessed value, but it climbs meaningfully over time. By 2030, roughly a third of your rental property's assessed value will be deducted before your tax bill is calculated, a substantial shift from current law.
This phase-in mirrors the multi-year approach the state took with the homestead changes, spreading the impact out rather than implementing it all at once.
Do You Need to Apply for This?
Based on how the state has implemented similar credits, including the new homestead credit, which applies automatically without a separate application, county auditors are expected to apply this rental property deduction without requiring a new filing in most cases.
Given how new this provision is, confirming directly with the Hamilton County Auditor's office that your rental properties are receiving the correct deduction on your 2026 bill is a smart, low-effort check.
The New Transparency Portal Is Worth Using
SB 1 also required the state to build a property tax transparency portal, giving taxpayers an easier way to compare their current bill against prior years. Once available, this tool should make it considerably easier to verify that new deductions, including this one, are actually reflected correctly on your rental property's bill.
What This Means for Your Hamilton County Portfolio
A gradually growing deduction on your assessed value is a genuine, multi-year tailwind for rental property profitability in Westfield and across Hamilton County. Our accounting team tracks these changes directly so our owners see the benefit reflected accurately, rather than discovering a discrepancy after the fact.
