For the STAR credit, I am not completely sure if what I entered is correct? Should I enter it anyway?

What if the amount I entered for STAR credit is incorrect?

If you are still working on your NYS return, you should enter your STAR credit as per the information listed here (or on the portal here) if you are unsure of the amount.

If the amount you entered is significantly off and you already filed your return, you may have to file an amended return if the state does not adjust your return automatically. For more information on amending your state return, click here.

I'm not sure how the STAR credit affects your state tax return (if you got it wrong).

The STAR credit is handled in 2 different ways.  If you bought your current home before about 2017, the credit is a direct reduction of your tax bill.  If you bought your house after that, you pay the full amount of your property tax and then you get a rebate check from the state.  I believe the instructions tell you to enter the amount of the rebate check, but to leave it blank if you are one of the older accounts that gets a direct credit on your bill.

Also remember, that when entering your property tax for your FEDERAL tax deduction, you should enter the net amount after subtracting the rebate (if you got one).
