Your tags must be kept up to date. There is only a 30 day grace period until you are penalized for a late tag. The penalty is $8.00 for each month that has elapsed. The Oklahoma Tax Commission charges $1.00 every day up to a total of $100, then other fees arise having to pay the $100, in addition to other late fees that are more than the Tribe's present $8.00 fee per month. Only waivers are given by the Director of Tax Commission under rare circumstances if the vehicle has lapsed more than a year.
