Maryland Form PV (Personal Tax Payment Vouchers) print out each year for us, but we have ignored these for years assuming they were "suggested payments" for the upcoming year (we pay what's due for the current filing tax year via direct debit). Never had a problem. My son had the same forms print out last year and ignored them too. However, in January he received a bill from Maryland with penalties and interest from not making the 4 payments. So are the payments mandatory, or just suggestions? I'm so confused.
