Massachusetts Overtime Pay Calculator

Massachusetts sets its own overtime rule under Mass. Gen. Laws ch. 151 §1A, requiring 1.5 times the regular rate for hours worked beyond 40 in a workweek — the same 40-hour trigger as federal law, but enforced under a distinct state statute with its own exemption list and its own attorney general enforcement arm. Massachusetts does not require daily overtime, so the 40-hour weekly total is what matters, not the length of any single shift.

For decades, Massachusetts also required extra 'blue law' premium pay for many retail workers who worked Sundays and certain holidays, on top of any overtime owed. That separate premium pay requirement was phased out in stages and effectively ended on January 1, 2023, meaning Sunday and holiday work in Massachusetts retail is now paid the same as any other day unless a contract or collective bargaining agreement says otherwise — a meaningful and relatively recent change workers should know about.

Massachusetts's exemption list under ch. 151 §1A differs from the federal FLSA in some details — for example, Massachusetts has historically had narrower exemptions in areas like certain outside sales and specific retail/service roles, so a worker who is exempt under federal law is not automatically exempt under Massachusetts law. Both tests generally need to be satisfied for an employer to safely treat someone as exempt in Massachusetts.

Massachusetts wage and overtime enforcement runs primarily through the Attorney General's Fair Labor Division, not a separate labor department. Workers file a wage complaint with the AG's office, and Massachusetts law requires filing this complaint (or getting a private right-to-sue letter from the AG) before bringing certain private wage lawsuits, a procedural step unique to Massachusetts that surprises many workers.

Massachusetts has a three-year statute of limitations for wage claims, including unpaid overtime, which is longer than the federal FLSA's standard two years. Massachusetts law also provides for mandatory treble (triple) damages for proven wage violations under Mass. Gen. Laws ch. 149 §150, making Massachusetts one of the more worker-favorable states for recovering unpaid overtime once a violation is established.

A common trap is employers assuming the old Sunday/holiday blue law premiums still apply, or conversely assuming they never applied — the safest approach for workers is to check current pay stubs against the 2023 phase-out date and flag any remaining contractual premium obligations separately from ordinary overtime. Another trap involves misclassifying inside sales or certain retail supervisory staff as exempt under the federal test while ignoring the stricter or different requirements under Massachusetts's own statute.

Massachusetts's mandatory treble damages provision means employers who lose a wage claim generally owe three times the unpaid amount, not just the shortfall itself, which raises the stakes considerably compared to a purely federal FLSA claim. Tipped workers face a $6.75/hr direct cash wage in 2026 as long as tips bring total pay to $15.00/hr, but overtime must be calculated on the full $15.00 minimum, not the reduced tipped wage.
