The firm
A property tax firm built around its own software.
Reserve Tax Group is the licensed appeal practice of Reserve. We combine the discipline of a top-tier tax consultancy with a valuation engine no traditional firm can match, and we answer to one standard: the reduction on your bill.

Why we exist
The best appeals never got filed.
Property tax is the largest line item on most real estate, and the most under-managed. The reason is simple: reviewing every parcel by hand is uneconomic, so consultants cherry-pick a few, charge a quarter to a third of any savings, and leave the rest of the portfolio on the table.
Reserve Tax Group was built to invert that. We built a valuation engine that can price an entire portfolio in the time a traditional firm prices one building, then put licensed counsel behind it to file and argue what the model finds. The result is broader coverage, a lower fee, and one firm that owns the whole engagement instead of a patchwork of local consultants.
We represent owners, operators, funds, and franchise groups, including Burger King franchisees under the brand’s preferred vendor program.
Leadership
Nathan Davidi
Founder & Chief Executive Officer
Nathan founded Reserve Tax Group after roughly four years in property tax consulting at Deloitte, where he saw first-hand how much value never reached owners because the manual model could not scale. He holds a Master of Science in Business Analytics from Cornell University and is an alumnus of the University of Connecticut.
He built Reserve's valuation engine and assembled the licensed team around it, with a single conviction: the analytical rigor of a national consultancy should be available to every owner, not just the largest accounts.
