Here are some ways to figure it out:
- Checkbox 10 "Other" on Form 1098 from your mortgage company.
- Review your bank or credit card records if you paid the property/real estate tax yourself.
- Go to your city or county tax assessor's website and look for a link to Property search or Property Tax records.
Keep in mind
- If you pay your property tax with your mortgage, you can only deduct it after your lender has paid the tax on your behalf. You can contact your lender to find out when they typically make these payments. (For example, a lender might make the payment in October to cover the total amount of the following year’s taxes; or they might make quarterly payments. It depends on the taxing authority in your location).
- Claim the deduction in the year you made the payment. If you paid your 2020 property tax on December 14, 2019, claim it on your 2019 return.

How has the property (real estate) tax deduction changed from 2017 to 2018 and later due to Tax Reform?
Property (real estate) tax ]is part of a combined deduction: Property taxes (real estate taxes + personal property taxes); combined with sales tax or State and local income taxes.
Under the new tax law, this deduction is capped at $10,000 ($5,000 if married filing separately). Prior to that, there was no cap. Taxpayers must itemize to get this deduction – that part hasn't changed.
This hypothetical example illustrates the differences:
2018 and later
Deductible amount = $5,000 (married filing separately) or $10,000 (all others)
Deductible amount = $6,500 (married filing separately) or $13,000 (all others)
