It depends on if you took the Standard Deduction or Itemized deductions on your 2017 return...and your tax bracket.  For example, if you are in the 15% tax bracket and Itemized deductions, it's possible you could get a refund of 15% of that sales tax.  However, this only works IF on the Schedule A (Itemized Deductions) you claimed sales tax and not the state "income" tax deduction (line 5).   I would suggest looking at your tax return to confirm you itemized on Schedule A, then look at line 5 of that form and see what would be higher...sales tax or income tax.   Hope that helps with your decision.

Thanks for the reply. I have not be able to Itemize for a long time so I am guessing  my return will stay the way it was.

If that is the case, then yes, it's unlikely it would benefit you.  You're welcome!
