Hello,
I and my partner owns the house. We are not married. Our property tax is more than $10k. My partner uses standard deduction so property tax doesn't help for standard deduction; however, she puts partial of property tax less than $10k in tax filing, and already filed. My tax deduction is itemized, so I can claim for property tax. I could see if I put total property tax instead of only $10k, I can get more state tax refund, here are my two questions.
1. Can I still put total property tax in tax filing even though my partner already put some amount of property tax in my partner tax filing?
2. If the answer of question 1 is no, is there anything I can do to be able to put total property tax for my tax filing such as requesting my partner tax amendment?
You can only claim the property tax that you actually paid - you cannot claim what someone else pays. You must have proof that you paid it, CC or bank statements, receipts, cancelled checks, etc.
In this scenario, property tax is paid from joint account that has both myself and my partner name on it, so can I still claim total property tax since my partner doesn't use property tax for standard deduction?
