Getting Started with CARS

Enrolling as a User or changing your access to CARS

Instructions for enrolling as a CARS user or adding or removing access to CARS can be found in the CARS New User Guide.

As part of the Common Approach to Identity Assurance (CAIA), CARS will be adopting multi-factor authentication in Q3 2023 (CY).

For more information on CAIA, please read the CARS CAIA Onboarding Guide.

For any CARS User that is requesting the role of “Legacy TAS Viewer” they must also submit the CARS Legacy TAS Viewer Role Request Form to CAB.CARD.FA@fiscal.treasury.gov with documentation of a business justification for needing access to that role.

If you have questions, call or e-mail the Treasury Support Center:
