Every state has a different deadline, ratio, and cap — the rules are not portable
For a UHNW owner with properties in multiple states, property tax is not one system but many — and the differences are enormous. A $5M home costs roughly $115,000 per year in New Jersey and roughly $25,500 per year in Colorado. Each state has a different assessment ratio, a different appeal deadline, a different reassessment cycle, and different exemptions. This is the complete comparison for luxury owners, cross-linked to the detailed guide for each market.

The Pattern That Holds in Every State
Regardless of which state your luxury property is in, the same fundamentals apply: 30–60% of properties are overassessed, fewer than 5% of owners appeal, and 40–60% of those who do win reductions. The deadline is the single most important date, comparable sales (ideally including off-market transactions) are the primary evidence, and at $3M+ the dollar amounts justify professional representation. The state determines the deadline, the ratio, and the cap — but the strategy for winning is consistent everywhere. See: How to Win a Luxury Property Tax Appeal.
Ryan Brown, Principal Broker & CEO — Own Luxury Homes®
“A client with homes in four states once told me he assumed property tax worked the same everywhere and his accountant handled it. His New Jersey home was costing him four times what his Colorado home cost on a similar value, and nobody had ever appealed any of them. Property tax is the most state-specific cost in real estate. The owner who treats it as one system is leaving money in every state at once.”
Which state has the highest property taxes for luxury homes?
New Jersey has the highest effective property tax rate in the US at approximately 2.3%, with Essex County averaging 2.54%. A $5M New Jersey estate costs roughly $115,000 per year. Illinois (Cook County) and Texas are also among the highest.
Which state has the lowest property taxes for luxury homes?
Among major luxury markets, Colorado has one of the lowest effective rates at approximately 0.51%. A $5M Colorado property costs roughly $25,500 per year — less than a quarter of the New Jersey cost on the same value. Tennessee and Florida are also relatively low.
Do property tax appeal rules differ by state?
Significantly. Each state has its own deadline, assessment ratio, reassessment cycle, and appeal process. Texas reassesses annually with a May 15 deadline; California reassesses only on sale; Colorado reassesses every two years with a June 1 deadline. The strategy for winning is consistent, but the rules are not portable between states.
