MAS refresh checklist: Refresh 31, 32 and 33

Each MAS refresh changes the solicitation, and a mass modification brings those changes into your contract. Read GSA's Significant Changes document, mark what touches your SINs, and accept the mass modification before its deadline. Refresh 32 is the latest, and Refresh 33 is planned for October 2026.

  • Monthly TDR reports are due within 30 calendar days after month-end, including zero-sales months. See the TDR guide and how to check a TDR file.

GSA's notices describe planned changes and drafts. The final solicitation refresh and the mass modification you receive govern.

Checklist

Seven steps for every refresh

  1. Step 1

    Read the refresh's Significant Changes document

    GSA lists every refresh on the Vendor Support Center's MAS Solicitation Refreshes page, with a Significant Changes document and the solicitation-level SF30. For an upcoming refresh, GSA posts an advance notice on its Interact MAS community first.

  2. Step 2

    Mark the changes that touch your SINs

    Most changes apply to specific Large Categories, subcategories or SINs. Note which ones affect the SINs on your contract, and which apply to every contract.

  3. Step 3

    Accept the mass modification before its deadline

    Each refresh reaches existing contracts through a mass modification with an acceptance window. For Refresh 33, GSA's notice says the mass modification must be accepted no later than 90 days after it is issued. If you miss one, the contract-level SF30 you receive later can bundle the changes from several refreshes.

  4. Step 4

    Review new clauses and representations

    Refreshes add and update clauses. Read each new clause and any representation it asks you to make before you accept.

  5. Step 5

    Update your catalog and price files

    Some refreshes change what your FAS Catalog Platform files may contain. Refresh 32, for example, removed the National Stock Number column from the FCP Product file.

  6. Step 6

    Check the product-specific rules if you sell products

    Refresh 32 added End-of-Support expectations for product offers, and Refresh 33, planned for October 2026, is set to add a product-substitution requirement. Read the exact wording in the final solicitation for your Large Category.

  7. Step 7

    Keep monthly reporting on schedule

    A refresh does not pause Transactional Data Reporting. Monthly reports are still due within 30 calendar days after month-end, including zero-sales months.

What is a MAS refresh?

A refresh is an update to the GSA Multiple Award Schedule solicitation. GSA publishes the changes, and a mass modification brings them into existing contracts once the contractor accepts it.

What is the current MAS refresh?

GSA's Vendor Support Center lists Refresh 32, from June 2026, as the latest. Refresh 33 is planned for October 2026, according to GSA's advance notice updated September 24, 2026.

How long do I have to accept the Refresh 33 mass modification?

GSA's advance notice says the Refresh 33 mass modification must be accepted no later than 90 days after it is issued.

Did Refresh 32 or 33 change TDR reporting?

Neither GSA's Refresh 32 Significant Changes document nor its Refresh 33 advance notice lists a change to Transactional Data Reporting. TDR became mandatory for all MAS SINs under Refresh 31.
