Every Indiana taxing unit must post its Notice to Taxpayers (Budget Form 3) for the 2027 budget to Gateway by October 13, 2026. What each field means — proposed levy, current levy, percentage change, hearing details — and why the advertised number is a ceiling, not a forecast.
Gateway, PPOP-IN, the DLGF transparency portal, county GIS portals, SDF data, township lookup, memo library — the complete map of free government tools for Indiana property taxpayers, and what each one is actually for.
Your TS-1 statement is the output of four systems handing off data: county CAMA, the auditor's deduction rolls, DLGF rate certification via Gateway, and the treasurer's billing system. Tracing the pipeline tells you exactly where any error was born.
Every layer of Indiana property tax software, mapped: state systems like Gateway and PPOP-IN, the CAMA platforms counties run, online payment portals, and the lookup, data, and appeal tools taxpayers actually use.
