Massachusetts Mileage Reimbursement: Mandatory, With Triple Damages

Massachusetts requires employers to reimburse employees for business travel expenses, including mileage. Employers who violate this face treble damages, three times the unpaid amount, plus attorney's fees. It is one of the harshest penalties in any state.

The Law: 454 CMR 27.04

Massachusetts regulation 454 CMR 27.04(4)(b) requires employers to reimburse employees for mileage and transportation expenses incurred during the workday. The rule is specific: if you are "required or directed to travel from one place to another after the beginning of or before the close of the work day," your employer owes you for travel time and transportation costs.

This covers mileage, parking fees, tolls, and other essential costs of job-related travel.

The Penalty: Treble Damages

Failure to reimburse violates the Massachusetts Wage Act. Courts must award treble damages, three times the amount owed. This is not discretionary. The statute requires it.

If your employer owes you $3,000 in unreimbursed mileage, a successful claim awards $9,000 plus your attorney's fees. This makes Massachusetts, dollar for dollar, the riskiest state for employers to ignore mileage reimbursement.

What Is Covered

Travel between work locations during the day. Driving from your office to a client site, from one job site to another, or to a meeting at a different company location. Your regular commute, home to your primary office, is not covered.

Covered expenses include:

• Mileage (most employers use the IRS rate of 72.5¢/mile)
• Parking fees at work-related locations
• Tolls (the Mass Pike and harbor tunnels add up)

Who Is Exempt

The reimbursement requirement applies to most W-2 employees. Exemptions include:

• Outside sales workers (as defined by the regulation)
• Agricultural employees

Independent contractors (1099) are not covered. If you are self-employed in Massachusetts, you deduct business mileage on Schedule C. Massachusetts has a flat state income tax of 5% (plus a 4% surtax on income over $1M), so your federal mileage deduction reduces your state tax bill too.

No Set Rate, But a Clear Standard

Massachusetts does not mandate a specific cents-per-mile rate. The IRS rate of 72.5¢/mile for 2026 is widely accepted as reasonable. Employers can use a different rate, but it must actually cover the employee's costs. Underpaying consistently opens the door to a Wage Act claim.

How to Track Your Miles

Keep a mileage log with the date, destination, purpose, and miles for each trip. Whether you are tracking for employer reimbursement or a self-employment deduction, the IRS requires contemporaneous records.

FAQ
