How to overpay real estate taxes?

[PennyPincher]

The new Federal tax law restricts state and local taxes to $10,000 per year.  I live in a high tax state.  I also pay the AMT. It appears the AMT prevents any substantial tax advantage of doing this.  How can I pay future RE taxes and get the state and local tax deduction in fiscal year 2017?

Did you receive a 2018 property tax bill from your city/county so that you know the amount to be paid in 2017 for the 2018 property taxes owed?

[PennyPincher]

No.  I have not received the 2018 tax bill.

Then you cannot prepay the 2018 property taxes in 2017 and deduct that payment on your 2017 tax return.
