State and local tax deductions are limited to $10,000 PER RETURN. But you can add up all the property taxes you pay on all homes you own. Rental property is treated differently.
The SALT deduction allows taxpayers to deduct state and local taxes paid from their federally taxable income, however the 2017 Tax Cuts and Jobs Act (TCJA) capped the deduction at $10,000 per year through 2025.
Consult your tax preparer on your own situation.
