A quiet change in Connecticut's property tax law could reduce annual assessments on older commercial vehicles—but only if you understand how it works.
Most Connecticut trucking and transportation business owners don't realize that a provision buried in SB362 fundamentally changed how the state assesses property taxes on vehicles 20 or more years old. The change takes effect October 1, 2026, and it directly affects your bottom line.
Here's what changed: Connecticut previously used a flat $500 minimum floor when calculating the assessed value of older commercial vehicles. Starting with assessment years on or after October 1, 2026, that floor is gone. Instead, assessed value will be the lesser of two numbers: 10% of the vehicle's original manufacturer's suggested retail price (MSRP), or $500.
If your business owns or leases commercial trucks, trailers, or other vehicles that are 20 or more years old, this applies to you. The change is particularly relevant for small fleets that rely on older equipment—the kind of vehicles that might have been assessed at $500 regardless of their actual condition or market value.
Under the old rule, a 25-year-old commercial truck with an original MSRP of $30,000 would have been assessed at $500 for property tax purposes. Under the new rule, the assessed value becomes the lesser of $3,000 (10% of $30,000) or $500—meaning it stays at $500.
But consider a vehicle with a lower original MSRP. A 22-year-old commercial van with an original MSRP of $20,000 would have been assessed at $500 under the old system. Under the new rule, 10% of $20,000 is $2,000—but since the cap is now $500, the assessed value becomes $500.
The real benefit emerges with vehicles that have very low original MSRPs. A specialized commercial vehicle with an original MSRP of $3,000 would have been assessed at $500. Under the new rule, 10% of $3,000 is $300—so the assessed value drops to $300, reducing your property tax liability.
The provision appears in Section 11 on Page 11 of SB362, An Act Concerning Revisions To Statutes Relating To Municipal Property Tax Assessment. It becomes effective October 1, 2026, and applies to assessment years commencing on or after that date. This means your first affected tax bill will depend on your municipality's assessment cycle—some towns assess annually, others on longer schedules.
Review your current fleet roster and identify vehicles that are 20 or more years old. Gather the original MSRP for each vehicle—your purchase records, manufacturer documentation, or historical pricing guides can help. When October 2026 arrives, work with your municipal assessor to ensure they apply the new calculation correctly.
This is a straightforward change, but only if you know it exists. The difference between a $500 assessment and a lower one compounds across multiple vehicles and multiple years.
