Property taxes chip away at a celebrity's net worth by turning home value into a yearly cash bill. A property tax is a local charge based on assessed home value, so a multimillion-dollar house can cost hundreds of thousands each year just to hold. Stars often own several luxury homes at once. Those bills stack, even when touring, filming, or endorsement income varies from year to year.

What one mansion costs to hold
Realtor.com reported that Jennifer Lopez and Ben Affleck's $68M Beverly Hills mansion faced about $476,000 in annual property tax, around $39,666 monthly, before insurance and upkeep, in its mansion cost breakdown. That monthly amount alone exceeds the price of many homes.
The effect on net worth is direct. Cash used for taxes cannot be invested, saved, or spent elsewhere. Holding an empty or unsold mansion keeps that drain going.
Why location changes the bill
The IRS defines deductible real property taxes as state or local value-based taxes levied for general public welfare at a uniform like rate. Local governments set the rate and spend the money, which is why property taxes were 28.9% of total U.S. state and local tax collections in FY2023, according to Tax Foundation data cited by Reason.
Rates differ sharply by state. Realtor.com, reporting Tax Foundation 2024 data, found New Jersey and Illinois tied for the highest effective rate on owner-occupied housing at 1.88%, or about $1,880 yearly per $100,000 of value, in its state tax rate map. On a $10M home, that math implies a far larger annual bill than in a low-rate state.
Why buying can reset the tax base
California's Board of Equalization says Proposition 13 rolled assessments to 1975 levels, caps the base rate at 1% plus voter-approved bonds, and limits annual growth to 2% maximum. Long-term owners therefore see slower growth in taxable value.
A purchase ends that protection. San Francisco's Assessor explains that a California purchase or new construction reassesses property to current market value, resetting the tax base for the new owner. A celebrity buying at a record price starts at that record value.
What deductions and exit taxes add
Federal tax law limits relief. The IRS states the 2025 federal SALT deduction limit rose to $40,000, $20,000 if married filing separately, capping how much property plus income or sales tax owners can deduct, in Publication 530 for 2025.
A star with a $476,000 bill cannot deduct most of it. Selling can bring another one-time hit:.
- Los Angeles Measure ULA adds a 4% transfer tax above about $5.3M and 5.5% above about $10.6M for housing programs, according to Commercial Observer.
- On a $68M sale, that percentage applies to the deal value, not the profit.
- The seller therefore pays recurring annual bills while holding plus a large exit tax when leaving.
