A Jefferson County tax waiver is for plate paperwork
Jefferson County's tax waiver, also called a statement of non-assessment, is mainly a vehicle-licensing document for people who did not owe personal property tax.
In Jefferson County plate paperwork, a “tax waiver” is not a break on a bill. It is the local name for a statement of non-assessment, the document showing that a person, business, or corporation did not owe personal property tax for a specified tax year.
New Missouri residents, people licensing a first vehicle or trailer, and people who did not own taxable personal property on January 1 are the ones most likely to run into it. The license office may ask for proof that no tax was due before it can finish the plate transaction.
Jefferson County’s tax-waiver instructions are the place to start, along with the proof the county asks for, since the plate office may not be able to sort out a missing non-assessment record at the counter.
