Proposing a constitutional amendment authorizing the legislature to exempt from ad valorem taxation income-producing tangible personal property for a certain period of time.

HJR 66 proposes a constitutional amendment to allow the state legislature to temporarily exempt income-producing tangible personal property (like rental equipment or commercial machinery) from ad valorem taxes. This amendment would not immediately change tax rules but would give the legislature the authority to create such exemptions for a limited period. The bill does not specify which properties would be exempted or the exact duration, only authorizing future legislative action. This is a procedural step toward potential tax policy changes, not a direct tax law.
