Each state varies on how they handle deductions or credits related to property taxes. The amount and how it is applied varies state-by-state. It is likely that any assistance you received will reduce the tax benefit available to you.
If you received assistance under specified programs, any benefit received may reduce the amount you are allowed to deduct for mortgage interest and property taxes. Generally, if taxpayers do not pay out of pocket for an item, it minimizes the tax benefit, whether it be similar taxes, interest, medical expenses, education expenses, etc. Property taxes are itemized deductions and not refunded in their entirety on your return. They are included as state and local taxes with a combined deduction capped at $10,000. If your total itemized deductions are less than your standard deduction for your filing status, itemized deductions will not have any affect on your tax return, as the standard deduction will provide you with the most benefit.
