Massachusetts is what is referred to as a client-reporting state for unemployment insurance. Justworks needs this information to report unemployment taxes under customers' unemployment account numbers.
Here’s what we need:
1) Your Massachusetts Unemployment Account number
2) Your current Unemployment Tax Rate for Massachusetts
3) Third Party Administrator (TPA) access after your previous provider has filed for the quarter
Unsure of where to find the above? Please see the sections below with instructions for each requirement

Closing your withholding Account
To close your Massachusetts withholding Account:
1. Log in to MassTaxConnect
2. Click into the Withholding Tax account
3. Click "Close my tax account" in the top right corner of the screen and enter the following
4. Closure reason: Final Return Filed
5. Closure date: (If Justworks effective date is the first day of a quarter, use the day before: e.g., 01/01/17 effective date → 12/31/16 end date. Otherwise, use the quarter-end date following the effective date: e.g., 05/01/16 effective date → 06/30/16 end date.)
6. Click “Submit”
If your company joined Justworks mid-quarter, Justworks will file for MA Unemployment for the whole quarter, as there cannot be duplicate filing under one Unemployment Account. In this scenario, you’ll need to send Justworks your quarter-to-date payroll reports. Please request all funds back from your previous payroll provider for Massachusetts State Unemployment. Since Justworks will file for the entire quarter, we will bill your company for the amount that has already been withheld.
If you’re having trouble completing the online account setup process, please contact the state’s customer service line for assistance.
