Your portfolio is over‑assessed.
We’ll prove it.
70% of U.S. commercial parcels are over-assessed. Most owners never appeal.
Reserve Tax AI is a technology company focused on identifying and challenging over-assessed property tax portfolios using advanced artificial intelligence. Instead of relying on manual spreadsheets, the platform scans every parcel, flags potential over-assessments, and manages appeals from start to finish. The solution is supported by senior counsel to help ensure quality, compliance, and strong case outcomes. Reserve Tax AI serves clients nationwide, helping organizations reduce tax burdens and improve portfolio performance and reporting.
Two-time Winner, July 2026
Property tax is the largest line item no one audits.
For most commercial real estate portfolios, property tax is the #1 operating expense, and the only one nobody underwrites at a parcel level. Every cycle, billions are quietly overpaid. The problem isn’t that owners don’t care. It’s that no tool was ever fast enough or precise enough to find it.
Four steps. One outcome.
Upload your portfolio. The AI scans every parcel, flags over-assessment, and licensed counsel files the appeal. Under 7 minutes of your time, then we handle the rest.

Assessed values, certified tax rolls, and appeal deadlines read straight from county assessors and appraisers, refreshed as rolls certify and notices mail. How we source data
Every win trains the next one.
Reserve’s machine learning models are trained on successful commercial property tax appeals: the comparables, evidence, and arguments that actually won reductions in front of real assessors. Every appeal Reserve Tax Group wins feeds back into the AVM, so the platform keeps learning what moves each county assessor and each jurisdiction. The more we win, the sharper the next filing gets, a compounding accuracy advantage traditional property tax firms cannot match.
The automated valuation model learns from real property tax reductions that cleared, not theory. Every valuation is anchored to comparables and assessment appeals that have held up before county boards and value adjustment boards.
Because Reserve tracks what persuades each assessor and jurisdiction, every appeal is built around the evidence that specific office responds to, across multifamily, industrial, retail, and office property tax.
Each reduction Reserve secures makes the next filing smarter. The property tax appeal success rate climbs as the dataset grows, so owners who join now inherit every win that came before.
