Clear comparisons, with the assumptions visible.

HoosierTaxBill is an independent project by Dustin Rasener to help Indiana residents understand school referendum estimates. It includes every active school proposal on the state’s November 2026 referendum list and does not recommend a vote. Tax changes are described numerically, without language intended to favor an outcome.

Two kinds of calculator

Carmel, Hamilton Southeastern, Noblesville, Westfield and Zionsville have full-bill scenarios that compare passage with failure. The other 33 district calculators estimate the proposed operating or safety referendum tax using the ballot maximum or a lower rate you choose. Those amounts are not the increase in your bill: existing referendum taxes have not yet been subtracted. Whiting’s separate construction question has an official example and source documents, but a personalized estimate still needs a verified rate or debt-payment schedule.

What the comparisons mean

Pass versus fail compares the same future year and assessed value. If the measure fails, an existing referendum continues through its own expiration date. The ballot’s stated tax increase uses a separate statutory calculation, which can differ from the pass/fail comparison.

Old law is a hypothetical comparison using pre-SEA 1 deduction rules and renewal of existing referendum rates. It is not another option on the ballot.

What is estimated

Calculations support ordinary homestead and non-homestead residential real property. They account for the modeled deduction schedules, tax caps, and supplemental homestead credit. Other property classes, mixed-use parcels, special deductions and credits, and separately assessed mobile or manufactured homes require a separate calculation.

Future referendum rates are projections or explicitly described assumptions. Other levy rates are held at their 2026 levels. Assessed-value growth is a visitor-selected assumption. These are estimates, not tax bills.

Sources and review

Each calculator links its sources and explains its rate assumptions. We’ve checked how the calculators apply tax deductions, caps and credits, how the five full-bill calculators handle existing referendum expiration dates, and how ballot dollar amounts are rounded. The new referendum-only calculators use maximum rates and terms from the state-approved questions. Their year-by-year tables hold your assessed value and chosen rate constant; they do not predict what the district will charge. Indianapolis’s four-year proposal ends in 2030 in this model.

Carmel’s 2028–2030 rates assume equal annual steps between the published 2027 and 2031 rates. HSE and Noblesville’s projected annual rates still need to be fully checked against district sources. We have not yet confirmed why Noblesville’s published $1.88 monthly average differs from this calculator. We are still checking which year’s deductions were used in Zionsville’s ballot example.

Address lookup and privacy

All 38 district calculators offer address lookup using public Indiana DLGF property, tax-bill and deduction files for assessment year 2025, payable in 2026. School assignments use the state school code on the tax record, checked against Indiana GIS tax-district labels. Selecting an address fills the calculator and opens your results. You can edit the inputs and check the property details against your latest tax bill. Properties outside the calculator’s coverage show an explanation instead of an estimate. These records are a starting value for future scenarios, not a forecast of your next assessment.

Lookup covers parcels with a usable street address and matching property records. Some records are missing, withheld, duplicated or have no street address. Properties marked confidential are excluded. Multiple parcels at one address remain separate. Farm, business, mixed-use and specially adjusted properties may appear in results but require a separate calculation. Owner names and mailing addresses are not included.
