Deductions & credits

Thanks for your help.

 

I understand that If I do not reach the $10,000 maximum in SALT (state and local) tax deductions, I may
deduct my QEE contribution (up to that $10,000 SALT cap). In this situation, I was told that I would take a deduction for my QEE contribution as “additional state income taxes paid" which is part of the Schedule A and the Tax Payment worksheet.

 

When I add the QEE contribution, my Georgia State tax bill gets two credits, one for the QEE contribution itself, and one for the "additional state income tax paid" so the Georgia state refund is larger (as I overpaid the state even without the QEE contribution). If I don't add the QEE contribution as "additional state income taxes paid" then the Georgia State tax bill gets only one credit, the one for the QEE contribution.

 

So my question is if I can add this "additional state income taxes paid" item even if initial SALT is more thank $10K.  And if not, then for the future (this year) I should estimate my W2 withholding to get me to $7.5K so next year I can be under the SALT limit - or does it make any difference?
