Limit amount a county tax assessor can increase assessed value of antique or classic cars

HB 4039 limits how much a county tax assessor can increase the annual property tax value of antique or classic cars. It requires assessors to provide written justification for any increase, based on inflation, cost-of-living data, or actual market activity - not random adjustments or projected county revenue needs. This applies directly to owners of qualifying vehicles who would receive the justification before any tax increase takes effect. The bill aims to prevent arbitrary value hikes by mandating specific, documented reasons for changes to property tax assessments.
