SALT and the Relocation Decision
The SALT cap is the most direct federal tax incentive for high earners to relocate from California, New York, and New Jersey to Florida, Texas, Nevada, or Wyoming. The math is straightforward: a California high earner paying $40,000 in state income tax and $20,000 in property tax ($60,000 total SALT) can only deduct $10,000 federally. The $50,000 in lost deductions costs approximately $18,500 in additional federal tax annually at the 37% marginal rate. That is a $18,500/year tax penalty for living in California that disappears entirely upon establishing Florida or Texas domicile — on top of eliminating the $40,000/year California income tax itself. Total financial incentive to leave California at $500K income: approximately $58,500–$65,000/year. Over 10 years: $585,000–$650,000.

FAQ
What is the SALT deduction cap and how does it affect real estate?
The SALT (State and Local Tax) deduction cap was introduced by the 2017 Tax Cuts and Jobs Act and limits the federal itemised deduction for state income taxes, property taxes, and local taxes combined to $10,000 per year ($5,000 if married filing separately). Before 2017, SALT was fully deductible, making high-tax states like California, New York, New Jersey, and Illinois significantly more affordable for high earners on a net-of-tax basis. The $10,000 cap effectively increased the after-tax cost of living in high-tax states by $20,000–$50,000+ annually for earners in the highest state tax brackets. This is the primary legislative driver of the California-to-Florida and New-York-to-Florida migration patterns that accelerated dramatically after 2018.
How does SALT affect California real estate buyers and sellers?
California’s 13.3% top state income tax combined with high property taxes creates a SALT situation where the $10,000 cap eliminates most of the deductibility. A California high earner paying $40,000 in state income tax and $15,000 in property tax ($55,000 total SALT) can only deduct $10,000 federally — losing $45,000 in deductions worth approximately $16,000–$18,000 in federal tax savings annually (at the 37% bracket). This hidden cost makes California real estate approximately 3–4% more expensive per year in net-of-tax terms than it appears before the SALT cap. For high-income California homeowners considering a move to Florida, the SALT cap improvement is approximately $16,000–$18,000/year in additional federal tax savings, on top of the $26,000–$110,000/year California income tax elimination.
Will the OBBBA change the SALT deduction?
The One Big Beautiful Bill Act as proposed includes modifications to the SALT deduction — the specific provisions have been one of the most politically contested elements of the legislation. Various versions have proposed raising the cap to $20,000–$40,000 or restoring full deductibility. Any SALT increase benefits high-income homeowners in California, New York, New Jersey, and other high-tax states by reducing their effective federal tax cost of remaining in high-tax states. However, even a doubled SALT cap ($20,000) captures less than half of the SALT burden for California’s top earners — meaning the financial advantage of Florida and Texas relocation would remain significant even with a SALT increase. Consult a CPA about the final OBBBA SALT provisions before making any relocation decision based on the proposed language.
Which states are most affected by the SALT cap?
States most financially affected by the $10,000 SALT cap: California (13.3% income tax + high property taxes), New York (10.9% income tax + NYC surcharge), New Jersey (10.75% income tax), Connecticut (6.99%), Massachusetts (5% income tax but high property taxes), Oregon (9.9%), Minnesota (9.85%). States unaffected by the SALT cap: Florida, Texas, Nevada, Wyoming, Tennessee, South Dakota, Alaska (no state income tax). The SALT cap is the primary financial mechanism driving the luxury real estate migration from high-tax states to no-income-tax states, which shows up in the strong demand for Florida, Texas, and Nevada luxury real estate among buyers from California and New York.
