Massachusetts Lemon Law Remedies

Massachusetts’s lemon-law remedy framework combines a tight 1-year / 15,000-mile Rights Period with Chapter 93A actual damages, double or treble damages on willful/knowing violations, and mandatory § 9(4) attorney fees — making Chapter 93A the load-bearing damages and fee engine in most Massachusetts lemon-law cases.

The basic recovery framework

For a Massachusetts Lemon Law refund under § 7N½(3):

Element	Amount
Cash paid (down payment + payments)	Full reimbursement
Loan payoff to lender	Paid directly to lender
Massachusetts sales/use tax (6.25%)	Reimbursed as collateral charge
Title, registration, and excise tax	Reimbursed
Dealer-installed options	Reimbursed
Incidental damages	Reimbursed when proven
Subtotal	(sum)
Less: reasonable allowance for use	Subtract
Net refund amount	Final amount
Plus: Chapter 93A damages + double/treble (when c. 93A applies, in court)	Variable
Plus: c. 93A § 9(4) mandatory attorney fees	Separate fee award

How the use deduction works

Massachusetts uses the statutory formula in § 7N½:

(Miles the vehicle traveled before the manufacturer’s acceptance of its return ÷ 100,000) × full contract price

For motorcycles, the divisor is 25,000 instead of 100,000. There is no separate multiplier and no percentage cap — the mileage fraction is applied directly to the full contract price, so the sooner the manufacturer takes the vehicle back, the smaller the deduction.

Massachusetts sales/use tax

Massachusetts applies a 6.25% sales/use tax on motor vehicle purchases. On a $42K vehicle, the sales tax is $2,625 — fully reimbursable as a collateral charge in a Lemon Law refund. Additionally, the annual motor vehicle excise tax (varies by city/town, typically $25 per $1,000 of valuation) is reimbursable for the year of purchase.

What makes Massachusetts distinctive

• Three separate Lemon Law statutes — § 7N½ (new), § 7N¼ (used), § 7N (Lemon Aid). Most states have one.
• Tightest combined Rights Period — 1 year / 15,000 miles. Tied with Michigan (1 year no cap).
• Shortest OOS threshold — 15 business days. NC at 20 business days is second-shortest.
• Chapter 93A § 9(3) mandatory demand letter — gates court action and triggers double/treble damages.
• Chapter 93A § 9(4) mandatory attorney fees — among the strongest UDAP fee provisions in the country.
• OCABR state arbitration — manufacturer required to participate if consumer elects. Few states have this.
• D. Mass. federal venue for Magnuson-Moss — Boston / Worcester / Springfield divisions.
