Car repair costs in Massachusetts: shop rates, labor and parts

One of the dearest hours in the country

The federal occupational wage survey finds about 12,700 automotive technicians in Massachusetts, paid 12 % more than the national mean. Multiplying the national band of posted shop rates, centered on $134, by that ratio gives the Massachusetts band. It is a model, not a count of what Boston or Worcester shops post; greater Boston may run above it and the Berkshires below. Parts cost the same from one state to the next in the catalog survey, so the gap with the national figure grows with the hours a job takes.

Authorization under the Attorney General's rules

Massachusetts regulates repair shops through Attorney General regulations under the consumer protection law, chapter 93A (Massachusetts Attorney General, 940 CMR 5.00). Before it starts, the shop records your name, the odometer reading and the work you asked for. It can bill you only if you signed a written authorization listing the repairs and the total price, if the prices are posted, or if you were told the repairs and the total and agreed. You may instead sign a waiver up to a dollar amount you pick yourself. No minimum job size applies.

If the price will pass the authorized or posted figure by more than $10, or if more work turns out to be needed, the shop must tell you and get your go-ahead before carrying on, and an approval given by phone has to be written down. Before you authorize the job, the shop must also let you know, by a sign on the wall if it likes, that you can have the replaced parts back at the end, or inspect them when they must go back to the manufacturer. Bring the authorized figure to the estimate checker to see whether it sits inside the state band.

An inspection every year

Massachusetts inspects every registered car once a year, safety and emissions together, and a newly registered vehicle has seven days to pass (Massachusetts registry rules, 540 CMR 4.03). A car that fails goes back for repairs and a retest. The state follows the federal rule for converters rather than the California one (U.S. EPA converter policy), so the estimate above uses a federal unit; the catalytic converter page sets out the difference.

Tax on the parts only

A Massachusetts shop collects sales tax on the parts. The labor is not taxed provided the parts are priced separately on the invoice and in the shop's records; a single lump sum is treated as the price of property and taxed in full (Massachusetts Department of Revenue, 830 CMR 64H.1.1). Asking for an itemized bill keeps the tax off the hours.
