It has to be a personal property tax, not an excise tax, in order to deduct it. Deductible personal property taxes are only those based on the value of personal property such as a boat or car. The tax must be charged to you on a yearly basis, even if it is collected more than once a year or less than once a year. To be deductible, the tax must be charged to you and must have been paid during your tax year. Taxes may be claimed only as an itemized deduction on Form 1040, Schedule A (PDF), Itemized Deductions.
