How to claim property tax deduction
Deducting Property Taxes
Property taxes are reported as an itemized deduction on Schedule A.
"Most state and local governments charge an annual tax on the value of real property. This is called a real estate tax. You can deduct the tax if it is assessed uniformly at a like rate on all real property throughout the community. The proceeds must be for general community or governmental purposes and not be a payment for a special privilege granted or service rendered to you." (Publication 530)
Property Taxes Paid Through Escrow Accounts
When property taxes are paid through an escrow account attached to a mortgage loan, the property owner can deduct only the amount paid out of the escrow account for property taxes.
Allocating Property Taxes When Real Estate is Sold
The IRS provides specific guidance on how to determine the amount of property taxes allocated to the buyer and to the seller:
"Real estate taxes paid at settlement or closing. Real estate taxes are generally divided so that you and the seller each pay taxes for the part of the property tax year you owned the home. Your share of these taxes
is fully deductible if you itemize your deductions." (Publication 530)
Certain Charges on Property Tax Bills are Non-Deductible
Sometimes a property tax bill includes charges or fees for services or assessments for local benefits. These are not deductible as property taxes. Also not deductible are transfer or stamp taxes or assessments made by a homeowner's association.
Service charges include things like water service, trash service, and services performed by the government that are related specifically to the property. "An itemized charge for services assessed against specific property or certain people is not a tax, even if the charge is paid to the taxing authority" (Publication 17).
Assessments for local benefits mean charges on your property tax bill that are for "local benefits that tend to increase the value of your property. Local benefits include the construction of streets, sidewalks, or water and sewer systems" (Publication 530). Because these expenses are related to increasing the value of your property, these expenses are not deductible as property taxes. Instead, these expenses increase your cost basis in the property.
