Definition

IRS (Internal Revenue Service) contracts for IT modernization, taxpayer services systems, document management, and cybersecurity. One of the largest IT modernization programs in government.

Why does IRS matter?

(Internal Revenue Service) is a agency concept federal contractors and grant writers run into across solicitations, regulations, and award filings

Where this matters in federal contracting

IRS is a federal agency, sub-agency, or contracting authority. Agencies like IRS concentrate procurement around specific missions, statutory authorities, and budget lines — and contractors who study them gain visibility into the program offices that own the work, the contracting officers who manage it, and the contract vehicles already in place. The fastest way to develop an agency strategy is to read awarded contracts (USAspending and FPDS make this trivial), trace the recurring vendors, and identify the program offices that buy what you sell. Bureauify's agency pages aggregate this picture; the related entries above name the adjacent agencies and authorities IRS most often partners or shares vehicles with.

Meaning in practice

IRS is a federal agency or sub-agency that owns budget, policy, or contracting authority.

Where you’ll see it

You will see it in award data, forecasts, budgets, procurement pages, and program-office references.

Common confusion

People often confuse the agency with a sub-agency, office, or component.

What to do next

Trace the buying pattern to the office or program that actually owns the work.
