What property tax deductions are available to homeowners on federal income taxes?

Homeowners who itemize deductions on their federal income tax return can deduct property taxes paid on their primary residence and other real property. The Tax Cuts and Jobs Act of 2017 capped the total deduction for state and local taxes, including property taxes and state income or sales taxes, at 10,000 dollars per year for most filers. This cap significantly reduced the benefit for homeowners in high-tax states. Mortgage interest remains separately deductible on loans up to 750,000 dollars for homes purchased after December 2017.
