FAR Part 53: Forms
The codified text (eCFR, as of 2026-10-02). Under the Revolutionary FAR Overhaul ↗, agencies follow class deviations with new text for many parts while the formal rules go through the Federal Register: check the solicitation and your contract's clauses, which rule.
In plain English
FAR Part 53 prescribes standard forms (SF), optional forms (OF), and agency forms for use in acquisition, and provides requirements for their use, exceptions, and computer generation. It matters to contractors because it tells you which forms must be used for solicitations, contracts, modifications, and other acquisition actions, and how you may or may not alter them.
Key rules
- Contracting officers must use the current edition of each prescribed form unless otherwise authorized by the regulation. (53.102)
- Agencies may not alter a standard form or use a different form for the same purpose without first obtaining an approved exception. (53.103)
- Standard and optional forms may be overprinted with names, addresses, and other uniform entries that do not alter the form, and no exception approval is needed for overprinting. (53.104)
- Forms prescribed by Part 53 may be computer generated without exception approval if the name, content, and sequence of data elements are unchanged and the form carries the Standard or Optional Form number and edition date. (53.105)
- Executive agencies must obtain standard and optional forms from the GSA Forms Library. (53.107)
- Contracting officers must insert the clause at 52.253-1, Computer Generated Forms, in solicitations and contracts that require the contractor to submit data on Standard or Optional Forms prescribed by this regulation, and unless prohibited by agency regulations, forms prescribed by agency supplements. (53.111)
- SF 1449 is prescribed for use in solicitations and contracts for commercial products and commercial services. (53.212)
- SF 30 is prescribed for use in amending invitations for bids, modifying purchase and delivery orders, and modifying contracts. (53.243)
Who does what
- Use the current editions of forms unless otherwise authorized under the regulation.
- Insert the clause at 52.253-1, Computer Generated Forms, in solicitations and contracts that require the contractor to submit data on Standard or Optional Forms prescribed by this regulation, and unless prohibited by agency regulations, forms prescribed by agency supplements.
- When required by the solicitation or contract, submit data on Standard or Optional Forms prescribed by this regulation, and unless prohibited by agency regulations, forms prescribed by agency supplements.
- Do not alter a standard form prescribed by this regulation or use for the same purpose any form other than the standard form prescribed without receiving in advance an exception to the form.
- Obtain standard and optional forms from the General Services Administration (GSA) Forms Library.
In practice
- When you bid or perform, use the exact form edition required by the solicitation or contract; do not substitute your own form unless an exception has been approved.
- If you computer generate a prescribed form, keep the name, content, and sequence of data elements unchanged and include the form number and edition date.
- You may overprint standard and optional forms with your name, address, and other uniform entries that do not alter the form.
- If you need to continue a form, use plain paper of similar specification or a specially constructed continuation sheet, and annotate it with the reference number of the document.
Common pitfalls
- Do not alter a standard form or use a different form for the same purpose without an approved exception; doing so may make your submission noncompliant.
- Do not use an outdated edition of a form; contracting officers are required to use current editions unless otherwise authorized.
- Do not assume you can computer generate a form without including the form number and edition date; the regulation requires them.
- Do not forget that the clause at 52.253-1 may be inserted in your contract if you are required to submit data on prescribed forms, so you must follow its requirements.
