Can I take my personal property taxes off my taxes my fiancé already claimed them

[CarolynM]

Yes, you can remove your personal property taxes if you have not already filed your tax return.

Go to Deductions & Credits

Scroll to Cars and Other Things You Own

Select Personal Property Taxes, select Edit

If you are taking the standard deduction ($12,000 for single filers) this removal will have no impact on your tax return
