The number one reason for not getting your Motor Vehicle tax bill is that your registration with the DMV had expired when the bills were generated. Re-register your vehicle with the DMV and you should get a supplemental or regular tax bill when they are generated 2 times a year (July and January). DMV registration issues can include: Plate changes, emissions test failures or non-compliance, changes of address, wrong domicile classification (What Town your vehicle is registered in) Orange is Town 107, Death of one of the owners and subsequent owner redesignation, and #1 failure to register your vehicle on time. Check online at the CT Department of Motor Vehicle website to verify your information before coming to the Tax Office. DMV errors must be cleared first since our data source is the CT DMV database.
