On my VA state tax return, there's a line called Addition to Tax. I don't know what this is or why it's there. Can someone explain, please? The same amount shows up on page 1 of the return as Addition to Tax, Penalty and Interest. We used TT last year and paid the amount due by the filing deadline. I imagine this can't be a penalty or interest. Taxes were withheld throughout the year and the amount we owe was calculated. This Addition to taxes is a below-line addition to what we owe.
