Olivia,
I think the income tax proposal is to take your annual income tax bill and multiply it by 1.05 or 1.025, depending on whether the state gets enough federal funding in Porkulus. It has nothing to do with how much you owe when you file taxes.
” It has nothing to do with how much you owe when you file taxes.”
It’s a 5% sur tax if you owe money when you file your tax return.
