Grayson County is requesting to turn off the automatic calculation of the late fees and penalties in SIT. Currently, there are a lot of factors affecting the late fees. For motor vehicle accounts, it has to be postmarked by the 10th of the month to avoid late filing penalty. For heavy equipment, it is the 20th. The receipt date also influences the fees, so they also have to check the receipt dates when making the payment. Grayson County would like to turn off this automatic feature and let them manually code the late fees.
