If Amanda and Steve Smith itemize deductions, what amount can they claim for combined property and state income taxes?

The correct amount for combined property and state income taxes that Amanda and Steve Smith can claim when itemizing deductions is $10,000. This figure aligns with the limitation set by the Tax Cuts and Jobs Act, which placed a cap of $10,000 on the combined total of state and local taxes (often referred to as SALT deductions) that taxpayers can deduct on their federal income tax returns. This limit applies regardless of whether the taxes are from property taxes or state income taxes, meaning that if their combined state income tax and property tax exceed $10,000, they can only deduct up to that cap. This is why $10,000 is the amount they can effectively claim when itemizing.
