It seems worse than an interest free loan. You become just another creditor when the state cannot pay its bills. You will be forced to overpay your taxes and then your refund will be withheld, perhaps paid with an IOU.
This is what happens when our elected officials don’t grow a pair and tell every group with their hand out...”NO MORE ENTITLEMENTS” They tax me $1.00 and spend $2.50... then cry that there’s not enough money to cover commitments. Then raise my taxes to $3.00
