Applicability

Use MVU-29 only when the transaction fits

The transaction facts determine the form, not the other way around.

  • A vehicle purchased outside Massachusetts is being titled and registered in Massachusetts
  • The owner is claiming an exemption recognized by Massachusetts for the out-of-state purchase and use history
  • The prior tax was legally due, paid, not refundable, and the reciprocity requirements apply, or another published exemption path fits
  • The affidavit accompanies the Registration and Title Application and ownership documents
