The Massachusetts workers comp waiting period is the number of days you must be off work after a job injury before wage-loss benefits start — 5 days in Massachusetts, set by M.G.L. c. 152, § 29.
This guide explains how the Massachusetts workers comp waiting period is counted, when Massachusetts pays those days back, what is still covered during the wait, and what to do if your first check is late. Figures verified against Massachusetts sources as of October 2026.
Massachusetts at a Glance
| Waiting period | 5 days (M.G.L. c. 152, § 29) |
| Paid back after | 21 days of disability (M.G.L. c. 152, § 29 (if incapacity lasts 21 days or more, compensation is paid from the date incapacity began; if it lasts at least 5 but under 21 days, compensation starts on the 6th day)) |
| Medical care during the wait | Many claimants are covered for reasonable and necessary medical treatment from the first day under M.G.L. c. 152, § 30. The § 29 waiting period applies only to weekly wage benefits under §§ 34 and 35, not to medical benefits. Confirm with your insurer or the DIA. |
| First check due | 14 days. Under M.G.L. c. 152, § 7, within 14 days of receiving the employer’s first report of injury (Form 101) or the employee’s first written claim, whichever comes first, the insurer must either start weekly payments or send a written refusal to the DIA, the employer, and the employee (by certified mail). |
| Wage-loss rate | 60% of your average weekly wage |

How Long Is the Massachusetts Workers Comp Waiting Period?
Massachusetts applies a 5 days Massachusetts workers comp waiting period to wage-loss benefits — temporary total disability — not to medical care. The clock starts with your first day of disability, not the day you report the injury, so the two dates can differ. The minimum weekly rate for injuries on or after 10/1/2025 is 384.50, which is 20% of the state average weekly wage.
If a worker’s average weekly wage is below that minimum, they receive their actual average weekly wage instead. Massachusetts maximums and minimums change every October 1, not July 1 or January 1. Rates are set by the date of injury, so someone injured before October 1, 2026 stays on the rate for their injury date.
When the Massachusetts Workers Comp Waiting Period Is Paid Back
The second number matters as much as the first. In Massachusetts the Massachusetts workers comp waiting period is paid back once your disability lasts 21 days (M.G.L. c. 152, § 29 (if incapacity lasts 21 days or more, compensation is paid from the date incapacity began; if it lasts at least 5 but under 21 days, compensation starts on the 6th day)).
So a worker out for two weeks or more usually recovers the first 5 days; a worker back in a few days usually does not.
Massachusetts Workers Comp Waiting Period Rules at a Glance
Every number below comes from Massachusetts sources; the statute column is where to check it yourself.
| Waiting period (days) | 5 |
| Statute | M.G.L. c. 152, § 29 |
| Retroactive after (days) | 21 |
| Retroactive statute | M.G.L. c. 152, § 29 (if incapacity lasts 21 days or more, compensation is paid from the date incapacity began; if it lasts at least 5 but under 21 days, compensation starts on the 6th day) |
| Light-duty days | Under § 29, the waiting period applies to any injury that keeps the worker from earning full wages, and it covers partial incapacity under § 35 as well as total incapacity under § 34. The DIA guide says “full or partial” days count. This generally means days on light or modified duty at reduced pay count toward the 5 days. Confirm with the DIA and a licensed attorney. |
| First payment due | 14 days. Under M.G.L. c. 152, § 7, within 14 days of receiving the employer’s first report of injury (Form 101) or the employee’s first written claim, whichever comes first, the insurer must either start weekly payments or send a written refusal to the DIA, the employer, and the employee (by certified mail). |
| Wage-loss rate | 60% |
How Massachusetts Counts the Days
States differ on whether the day of injury counts, whether weekends and holidays count, and whether a half day at work breaks the streak. The Massachusetts rule is in the table above; when in doubt, count calendar days from the first full day you could not work and confirm with the insurer.
Under § 29, the waiting period applies to any injury that keeps the worker from earning full wages, and it covers partial incapacity under § 35 as well as total incapacity under § 34. The DIA guide says “full or partial” days count. This generally means days on light or modified duty at reduced pay count toward the 5 days. Confirm with the DIA and a licensed attorney.
What Is Covered During the Waiting Period
Many claimants are covered for reasonable and necessary medical treatment from the first day under M.G.L. c. 152, § 30. The § 29 waiting period applies only to weekly wage benefits under §§ 34 and 35, not to medical benefits. Confirm with your insurer or the DIA.
Report the injury to your employer in writing as soon as it happens, see an authorized doctor, and keep a copy of every form. Those three steps protect the claim whether or not the Massachusetts workers comp waiting period ends up being paid back.
If Your First Massachusetts Check Is Late
Call the Massachusetts Department of Industrial Accidents at (617) 727-4900. If the employer hasn’t sent Form 101 to the insurer within the required time, the worker can report the injury to the DIA directly. If the insurer hasn’t started payments or sent a written denial within 14 days, the worker may file a claim with the DIA. Many claimants also talk to a licensed workers’ comp attorney.

Why the Massachusetts Workers Comp Waiting Period Exists
Every state uses a waiting period to keep very short absences out of the wage-loss system, the way a deductible works on a car policy. The Massachusetts workers comp waiting period is on the shorter end of the national range of three to seven days, and the payback rule decides whether a longer injury recovers it.
If any part of the Massachusetts workers comp waiting period is unclear for your case, the state agency’s information line can confirm the count and the insurer’s deadline at no cost.
Next step: once the Massachusetts workers comp waiting period has run, the claim itself decides what you are paid. Our Massachusetts claim guide covers the reporting deadline, the forms and what to do if the insurer disputes the injury.
