SIN 541219 contractors: accounting and budget support for federal finance offices
Orders under SIN 541219 typically pay for people who reconcile fund balance with Treasury, clear suspense accounts, prepare budget justification material, build spend plans and help a CFO office get ready for its annual financial statement audit. GSA's scope text names transaction analysis and processing, accounting policy and procedure work, special studies of accounting operations, and fixes to budget formulation and execution.
Who holds it
The GSA eLibrary entry for SIN 541219 showed 414 contracts on 29 October 2026, held by 397 differently named companies. 320 of them (77%) carry the small business flag and 94 are other than small. Socio-economic flags on the same records: 8(a) 79, SDVOSB 73, WOSB 99, HUBZone 35.
Holders are based in 34 states and territories, led by Virginia (180), Maryland (75) and the District of Columbia (27); 68% sit in Virginia, Maryland or DC. The SINs most often held on the same contracts are 541611 management and financial consulting (383), 54151S IT professional services (224), 541211 Auditing Services (141), and a holder carries 7.7 SINs on average. 9 contracts are marked closed for new awards.
Neighbouring SINs and other routes
The neighbouring SIN 541211 is for the audit itself; agencies that buy audit readiness here usually keep the auditor on a separate contract because GAGAS independence rules stop a firm from auditing statements it helped prepare. Broader financial management consulting sits under 541611, which most 541219 holders also carry.
Federal spending in the matching industry code
USAspending.gov reports $795 million in federal contract obligations in fiscal year 2025 (October 2024 to September 2025) coded to NAICS 541219, other accounting services. The largest awarding agencies were Department of Defense ($525 million), Department of Homeland Security ($48 million), Department of State ($47 million). This counts every contract with that industry code, not only orders under this SIN, so it shows the size of the federal market rather than sales through the schedule (retrieved 29 October 2026).
A contract on the SIN shows that a firm may be ordered from, not that it has received orders. The sample rows below were each checked against the contractor's own eLibrary record.
