Week in Insights: Massachusetts Mileage Tax Plans Lack Nuance

Jan. 11, 2026, 3:00 PM UTC

It’s 5:00 p.m. on the interstate, and you’re sitting in heavy traffic. It’s 5:00 a.m. on a rural highway, and you’re the only conveyance without a saddle and a mane for miles. Under Massachusetts’ new vehicle mileage tax exploratory, both trips could be taxed the same. That would be a missed opportunity.

Earlier this month, state lawmakers introduced SB 2404, which would establish a task force and pilot program to explore a vehicle mileage tax. The goal is to replace the gas tax, which has seen dwindling revenue thanks to rising fuel efficiencies and electric cars. The proposed pilot would equip 1,000 volunteer drivers with mileage-tracking devices to evaluate how a per-mile fee would work in practice.

A per-mile fee is a reasonable upgrade from the gas tax. The downside of the Massachusetts proposal is that it assumes every mile driven imposes the same cost on society. But an additional vehicle on I-93 at rush hour contributes more to gridlock—and consequently emissions and lost economic productivity—than the same car cruising down a country lane at dawn.

A well-designed VMT pilot could introduce dynamic pricing, charging more during peak hours in high-congestion zones and less when roads are empty. Just look at New York. A bit over a year into the country’s first congestion pricing program, vehicle volume is down, air quality is up, and the city is on track to generate $500 million annually in net revenue.

Massachusetts should design the VMT pilot with congestion pricing in mind from first principles—testing variable rates based on time of day, road type, and even proximity to public transit alternatives. This would send a clear message: If you drive when and where it causes the most disruption and you have alternatives, you will pay accordingly.

Technically Speaking design by Jonathan Hurtarte/Bloomberg Tax

Hawaii’s “green fee” for cruise ships brings parity to accommodations and should survive constitutional scrutiny if the state successfully links cruise cabins to hotel rooms, Andrew Leahey argues in his latest Technically Speaking column.

“Hawaii’s approach offers a blueprint for other coastal states to follow suit,” Andrew writes, adding that equally applied taxes on land-based and waterborne lodging would sidestep the legal minefield of targeting ships or charging for harbor access. Read More
