How these estimates work
What’s on the ballot
Noblesville Schools has an operating referendum on the November 3, 2026 ballot. It authorizes a rate of up to $0.57 per $100 of net assessed value for up to 8 years, replacing the 2018 operating referendum ($0.37), which expires after 2026. A separate $0.08 referendum debt rate, approved in 2010, continues through 2032 regardless of this vote— so “fails” does not mean zero referendum tax. DLGF determination · district referendum page
Why we show two “passes” numbers
The ballot authorizes up to $0.57. The district has publicly committed to set a rate no higher than $0.41 for 2027 (and says it will not use the full $0.57 in all eight years), but that commitment is not legally binding and later years may be higher. We show the bill at $0.41 and at $0.57 so you can see both the plan and the ceiling. Source
This is also why you may have seen two very different cost figures: the ballot’s statutorily-required “$955 per year for a median $350,000 residence” is computed at the $0.57 maximum, while the district’s “$2.30 more per month” framing reflects its below-maximum rate plan. Both are arithmetic from the same law — at different rates.
Why does my estimate go down if it passes?
For many higher-value owner-occupied homes, the estimate with the referendum passing (at the district’s committed $0.41 rate) is slightly lowerthan the current bill. That isn’t an error — it’s how the 2025 property tax law interacts with the two referendum rates:
- Above roughly $333,000 in assessed value (in Noblesville City’s taxing district), the 1% constitutional cap already limits the non-referendum part of the bill, so that part is the same whether the referendum passes or fails.
- What changes is the referendum line: today’s $0.37operating rate applies to this year’s net assessed value; the proposed $0.41would apply to next year’s net assessed value, which the 2025 law makes substantially smaller — and the reduction is proportionally larger for higher-value homes.
- Above about $440,000 assessed value, the shrinking net assessed value outweighs the higher rate, so the estimated bill dips slightly below today’s.
This applies at the district’s committed $0.41rate. At the ballot’s authorized maximum of $0.57, the estimate increases for homes at every value — which is why both figures are always shown.
The 2025 property tax law (SEA 1)
Indiana’s 2025 reform changes homestead deductions each year: for taxes paid in 2026 your home’s assessed value is reduced by $48,000 and then by 40% of the remainder; for taxes paid in 2027 it’s $40,000 and 46%. It also adds a credit of 10% of your bill (up to $300) that excludes referendum taxes. Because referendum rates apply to that shrinking net assessed value, a 57¢ maximum in 2027 raises fewer dollars per home than it would have in 2026 — which is the district’s stated reason the replacement maximum is higher than the expiring 37¢ rate.

Estimates, not bills
- 2027 non-referendum rates are not certified until January 2027; we hold them at certified 2026 levels (2026 budget order).
- Assessed values come from Hamilton County’s public parcel data at lookup time and reflect the most recent assessment.
- This tool models owner-occupied homesteads only (1% cap class). Rentals, farms, and businesses follow different rules.
- Other deductions some households have (mortgage age 65+, veteran, etc.) are not modeled and would lower all three columns.
