A provision buried in Connecticut's property tax bill will change how your trucks, trailers, and equipment are taxed—and most business owners don't know it yet.
Most Connecticut trucking and transportation owners assume their personal property taxes work the same way across the state. They don't. Until now, municipalities could choose whether to use a standardized depreciation schedule for business equipment, or opt out and use their own methods. That flexibility ends October 1, 2026.
Senate Bill 362, titled "An Act Concerning Revisions To Statutes Relating To Municipal Property Tax Assessment," contains a provision that eliminates the municipal opt-in requirement for personal property depreciation schedules. Starting with assessment years that begin on or after October 1, 2026, every Connecticut municipality must apply the same cost-based depreciation methodology to all tangible personal property—trucks, trailers, machinery, equipment, and fixtures.
Personal property tax assessments directly affect your annual tax bill on vehicles, equipment, and machinery. Under the old system, your town could choose to follow a standardized depreciation schedule or develop its own approach. Some municipalities were stricter; others more lenient. This created inconsistency across the state.
The new mandatory schedule removes that local discretion. Your depreciation rates—and therefore your assessed values—will be determined by a statewide cost-based formula, not local judgment. For a trucking company, this applies to your entire fleet: tractors, trailers, specialized equipment, and any other tangible business property on your assessment rolls.
The change affects every business in Connecticut with personal property, not just transportation companies. But for fleet-heavy industries, the impact is more significant because equipment represents a larger portion of total business assets.
The provision becomes effective October 1, 2026, and applies to assessment years beginning on or after that date. This gives municipalities and assessors time to prepare, but it also means your 2026 tax bills may reflect the transition. You should expect your local assessor to begin implementing the new schedule in the months leading up to October 2026.
The specific language appears in Section 10 of SB362 (pages 9–10), which strikes the prior ordinance requirement that allowed municipalities to opt in to the depreciation schedule. By removing the opt-in language, the bill makes the schedule mandatory statewide.
Review your current personal property tax assessments and understand what depreciation methodology your municipality currently uses. When October 2026 approaches, contact your local assessor's office to confirm how the new statewide schedule will affect your specific equipment and fleet. If you have questions about how the depreciation formula applies to your assets, your assessor or a tax professional can walk you through the calculation.
This change is technical but real. It removes a layer of local flexibility and standardizes how Connecticut values business equipment for tax purposes. For transportation and trucking owners, that standardization may mean changes to your annual tax obligations.
