Can I pay the fourth quarterly estimated tax that is due January 17, 2017 in December 2016 so that I can deduct it for the 2016 tax year?

[VolvoGirl · Accepted solution]

Yes. I assume you mean a state estimated payment?   If you pay a state estimated payment in 2016 it can be deducted on schedule A for Deductions.  If you pay a federal estimate in January it still goes on your 2016 federal return as a payment.

Yes you can.

You do not deduct it per se, but rather will credit it against your taxes due.
