Can you write-off or deduct the convenience fee charged for paying property tax bills via credit card?

I live in Orange County, California. The tax assessor's office is offering the ability to pay my property tax bill by credit card (thus earnings me miles) through a third party vendor who charges a "convenience fee" of 2.5%. If I can deduct the fee, then it is a good deal for me. However, I'm not sure if I can.

I doubt it. It's not a tax and isn't part of your property taxes. The county reports how much your taxes are.

Reply:No. Not deductible. It is a personal expense.
