Advance Notice: MAS Refresh 31 and Upcoming Mass Modification

GSA’s Federal Acquisition Service (FAS) plans to release Multiple Award Schedule (MAS) Solicitation 47QSMD20R0001 – Refresh 31 in February 2026. This refresh introduces several important updates that will affect MAS contractors. (BUY.GSA.GOV 1/12/26)

After GSA issues Refresh 31, contractors must accept the related Mass Modification within 90 days. (ibid)

What’s Changing Overall

GSA will update the General Information section across MAS solicitations to:

  • Add new requirements for Artificial Intelligence (AI) systems and services, aligning with federal executive orders and OMB guidance.
  • Update proposal instructions that apply to all offerors.
  • Expand Transactional Data Reporting (TDR) to all remaining service SINs and make TDR mandatory for all MAS SINs.
  • Limit the Startup Springboard Program to vendors that qualify for FASt Lane.
  • Clarify that foreign replica weapons and inert ordnance are excluded from the MAS Program.
  • Update clauses and provisions to align with:
    • TDR requirements
    • Request for Offer (RFO) changes
    • Federal Acquisition Circular (FAC) 2025-06
  • Update subcontracting templates to reflect recent FAR changes. (ibid)

Important Change to Open Market Items

GSA has changed how contractors include open market items under MAS.

  • The previous flexible approach no longer applies.
  • Contractors must now use the Order-Level Materials (OLM) SIN and follow specific OLM rules.

GSA strongly recommends accepting the Mass Modification to add the OLM SIN if you do not already have it.

  • New MAS awardees will continue to receive a Mass Mod to add OLM.
  • Current contractors without the OLM SIN will receive a one-time Mass Modification to add it. (ibid)

Changes by Category

GSA will also revise instructions, templates, and descriptions for specific Large Categories, Subcategories, and SINs, including:

Office Management

  • Updates to office supplies and 3D printing SINs.

Human Capital

  • New and revised SINs covering human resources, talent acquisition, performance management, and retirement services.

Miscellaneous

  • Removal of subcategory limits for OLM instructions.

Professional Services

  • Updates to auditing, training, and workforce development SINs.

Transportation & Logistics

  • Revisions affecting vehicle services, package delivery, courier services, and equipment rentals.

Travel

  • Updates to employee relocation, lodging, and travel agency service SINs.(ibid)
