Massachusetts mileage questions split by context: workers' compensation, state employee travel, employer policy, and tax records do not use one universal rule.
Massachusetts has no single mileage rate. The Department of Industrial Accidents sets its own figure for workers' compensation travel to treatment — $0.62 per mile (from March 23, 2026) — Commonwealth employees travel under state employee rules, and an ordinary private-employer claim is decided by the employer's written policy, with the federal rate as the usual benchmark.
Massachusetts DIA publishes its own mileage table for injured workers traveling to and from medical treatment and certain approved rehabilitation activity; the figure in force is $0.62 per mile (from March 23, 2026).
State employee reimbursement can depend on whether travel is from home, the regular office, or a temporary assignment, with the reimbursable distance often limited to the lesser route.
For ordinary private-employer mileage claims, the practical workflow is employer policy, eligible business miles, and documentation rather than one universal Massachusetts mileage rate.
The three contexts do not share a number, and only one of them is published as a rate table.
| Context | 2026 figure | Set by |
|---|---|---|
| Workers' compensation travel to treatment | $0.62 per mile (from March 23, 2026) | Department of Industrial Accidents mileage rate table |
| Commonwealth employee travel | Transportation expenses for the lesser of home-to-assignment or office-to-assignment distance | Mass.gov state employee guidance on calculating auto mileage from home |
| Private-sector work mileage | Employer policy; the federal benchmark is 72.5 cents per mile for January through June and 76 cents per mile from July 1 | Employment contract or written policy |
Massachusetts mileage figures by context in 2026.
The IRS has not published a standard mileage rate for 2027. Until it does, two things decide what a trip pays: the year you drove it and the date within that year. A 2026 trip pays 72.5 cents per mile through June 30 and 76 cents per mile from July 1. Miles driven from January 1, 2027 will use whatever figure the IRS publishes next.
The next year's rate has arrived in December in each of the last nine years, between December 14 and December 31. An announcement is not always the last word. The IRS raised the 2026 figure on July 1, halfway through the year, so a 2027 claim may need two rate periods.
A state that publishes a rate for its own travelers follows its own calendar, so it can publish the next period before the IRS does. A private employer's rate changes when its own policy changes, or when the benchmark that policy follows moves. It does not change because the calendar year turns.

No. Massachusetts mileage reimbursement depends on the program or policy involved, such as workers' compensation, state travel, or a private employer's own reimbursement rule.
Because the state runs its own table for that program, so a workers' compensation claim uses a rate and a claim form that an ordinary employer reimbursement does not.
The DIA rate: $0.62 per mile (from March 23, 2026). Massachusetts runs its own table for travel to treatment and approved rehabilitation activity, and the insurer paying benefits provides the claim form.
