What is SF 30?
Standard Form 30, Amendment of Solicitation/Modification of Contract, is the standard form a contracting office uses to amend a solicitation or to modify a contract or order, with the change described in Item 14 and the document identified by its amendment or modification number.
The form has two halves that never apply at the same time. Item 11 applies only to amendments of solicitations: it states whether the hour and date for receipt of offers is extended or not extended, and it explains how offerors acknowledge the amendment. Item 13 applies only to modifications of contracts/orders: you check one box (A through D) to show the type of modification and the authority under which it is issued, and Item 13E states whether the contractor is or is not required to sign and return copies to the issuing office.
The printed form says the standard form was prescribed by GSA under FAR (48 CFR) 53.243 and that the previous edition is unusable. Its revision line reads STANDARD FORM 30 (REV. 11/2016). A back page gives instructions for the items that are not self-explanatory, including the effective-date rules for Item 3, the entries for Item 12, and how to describe the change and its effect on total contract price in Item 14.
Item 14 also carries a fixed statement: except as provided in the document, all terms and conditions of the document referenced in Item 9A or 10A, as heretofore changed, remain unchanged and in full force and effect.
Who needs to file SF 30?
The form is completed by the contracting office that issues it. That office appears in Item 6 (Issued By), with Item 7 used for an administering office if it is not the one in Item 6, and a contracting officer's name and title go in Item 16A.
Other people who deal with the form:
- Offerors, when the SF 30 amends a solicitation. They must acknowledge receipt of the amendment before the hour and date specified in the solicitation or as amended, using one of the methods printed in Item 11.
- Contractors, when the SF 30 modifies a contract or order. Item 13E states whether the contractor is or is not required to sign and return copies to the issuing office. Where signature is required, the signer's name and title go in Item 15A and the person authorized to sign signs in Item 15B.
Use the Item 9 side of the form for a solicitation amendment and the Item 10 side for a contract or order modification. The back-page instructions say the contracting officer's signature in Item 16B is not required on solicitation amendments and is normally affixed last on supplemental agreements.
When to file SF 30
The form is used when a solicitation is amended or a contract or order is modified. The SF 30 sets no filing deadline of its own; the timing rules are tied to the type of action.
For a solicitation amendment, an offer's acknowledgment must be received at the place designated for receipt of offers before the hour and date specified in the solicitation or as amended; failure to do so may result in rejection of the offer. An offeror who wants to change an offer already submitted may do so by letter or electronic communication that references the solicitation and the amendment and is received before the opening hour and date.
Item 3 (Effective Date) follows the back-page instructions. For a solicitation amendment, change order or administrative change, it is the issue date. For a supplemental agreement, it is the date agreed to by the contracting parties. Separate rules cover termination-related modifications.

How to submit SF 30
The SF 30 names no mailing address, portal or appointment process. What it prints depends on the type of action:
- Solicitation amendments: offerors acknowledge receipt at the place designated for receipt of offers in the solicitation, before the hour and date specified. Item 11 lists three methods: complete Items 8 and 15 and return copies of the amendment; acknowledge receipt on each copy of the offer submitted; or send a separate letter or electronic communication that references the solicitation and amendment numbers.
- Contract or order modifications: where Item 13E says the contractor is required to sign, the contractor signs and returns copies to the issuing office shown in Item 6.
Contact the issuing office for its address or electronic channel. FillingPDF lets you fill out and download the PDF; submission follows the channels above.
Common mistakes to avoid
- Completing both the Item 9 (solicitation amendment) and Item 10 (contract/order modification) sides; Item 11 applies only to amendments of solicitations and Item 13 only to modifications.
- Letting an offer's acknowledgment of a solicitation amendment arrive after the hour and date specified; the form warns this may result in rejection of the offer.
- Leaving the price impact out of Item 14; the back page requires one of three entries: increased by $, decreased by $, or unchanged.
- Setting out the Uniform Contract Format table of contents in Item 14; the instructions say it shall not be set forth in the document.
- Using a contractor name, address or code in Item 8 that differs from the original contract or order without a change made by this or a previous modification.
- Entering the wrong Item 3 effective date, for example not using the date agreed by the parties for a supplemental agreement.
- Not marking in Item 13E whether the contractor is or is not required to sign and return copies to the issuing office.
- Cramming several accounting classification changes into Item 12 instead of inserting an asterisk and the words "See continuation sheet".
