For contracts teams rebuilding clause lists after the FAR overhaul

FAR Overhaul Clause Crosswalk: paste your clause numbers, see where each one moved

FAR Overhaul Clause Crosswalk takes the FAR and DFARS clause numbers you paste from a contract, subcontract flow-down, template or proposal and shows, for each one, its codified number, the number under the applicable agency class deviation, the proposed permanent number, what changed, and your flow-down list in the new numbers. A contract carries the deviation number only where its awarding agency has adopted that deviation and it applies at the date of the solicitation or modification. It reads clause numbers only, never contract documents or controlled unclassified information, and every row links to the deviation, the eCFR or the Federal Register text it came from.

Read your own listEight lines free, no account. The whole dataset, 1,007 distinct clauses, published under 1,047 old and new clause-number pages, loads with the page and every lookup runs in your browser.

Paste the clause list from your contract, subcontract, template or proposal, one clause per line, with or without titles and dates. Nothing leaves your browser until you save.

For each clause: the number in the codified FAR or DFARS, the number under the applicable agency deviation (a contract carries it only where its awarding agency adopted that deviation and it applies at the solicitation date), the number in the proposed permanent rule, and what the official text says changed, each cited to the document it came from.

Which number applies to a given contract depends on the deviation the contracting agency has adopted and the date of the solicitation; the finder shows all three and names the source, it does not decide for you.

How current, and whose deviations. As at 27 Sep 2026. The codified FAR and DFARS from the eCFR, current to 24 Sep 2026. The overhaul model deviation text for FAR Part 52 (updated 1 Jul 2026) with GSA's provision and clause table of 1 Apr 2026. For DoD, the FAR Part 52 deviation 2026-O0038, effective 1 Feb 2026, and, separately, the DFARS class deviations, read clause by clause. The agencies acquisition.gov lists for each FAR part. The eight proposed rules of 23 Jun and 18 Sep 2026. No final rule has been published. Sources last checked 27 Sep 2026; what changed and when. Published by The Art of Service.

Two colleagues at a desk working through a bound document and a loose page side by side — Rebuild the flow-down template once, with every number traced to the deviation or rule that set it, instead of reading the deviations, the eCFR and the Federal Register clause by clause. The next solicitation or modification then becomes a lookup, not a research project, because the codified, deviation and proposed numbers sit side by side with their dates.

Paste the list as it leaves the contract, the exhibit or the matrix

One clause per line: 52.204-21 Basic Safeguarding of Covered Contractor Information Systems (NOV 2021), DFARS 252.204-7012, 52.212-5 Alt II, I.12 52.219-8, tabs, pipes or CSV. The regulation, the number, the alternate, a deviation marker and the clause date are read; a number the dataset does not hold is marked and never guessed.

Read the three numbers and where each comes from

Each line shows the codified number with its eCFR date, the number under the deviation with the deviation that sets it, the proposed number with its Federal Register citation, the disposition in the supplement's own abbreviations, and what the official text says changed. Open a line for the sources, the agencies and the confidence.

Take the new numbers back to the template

Eleven notes in a fixed order, from a number that moved to a clause date older than the current text. Each line says whether it flows down, from its own subcontract paragraph and from the flow-down lists, with the official words. With the prime contract's list beside the subcontract list, the flow-down gaps with the condition for each. An existing contract's clauses are not rewritten by a later deviation or proposed rule; they change only by modification. On Solo, the find-and-replace sheet for your template.

One clause per line, as it leaves a Section I list, a flow-down exhibit, a proposal compliance matrix or a template. A first line such as list: subcontract flow-down | agency: DoD | date: 2026-09-01 sets what the list is, the agency and its date.

Nothing is sent anywhere until you choose to save.

Where every line on this page comes fromNothing here is written while you wait. We hold the text of the FAR as codified (48 CFR chapter 1), the DFARS as codified (48 CFR chapter 2), the FAR overhaul model deviation text for Part 52, the GSA RFO Part 52 provision and clause table, the DoD class deviations, the eight proposed rules in the Federal Register and the GSAR and HSAR clause lists as codified, read clause by clause and checked against the copy we hold; every obligation FAR Overhaul Clause Crosswalk attaches is that text, cited to its clause. Where we do not hold a regime in full, the page names the obligation and says the text is not quoted. FAR Overhaul Clause Crosswalk does arithmetic on your own rows and quotes the obligation; it never rules on you. How this is built. Open the standards themselves.

Why a list, and not the regulation

The overhaul did not change one number; it gave many clauses up to three. The codified FAR still reads the old way, agencies issue class deviations that contracts carry where the agency has adopted them, and the Federal Register proposes permanent numbers that differ again. A contracts manager rebuilding a flow-down template is not asked to read the regulation; the question is which lines of the template changed, to what, and on whose authority. That answer sits in the clause list you already keep, read against the official tables, one line at a time, in your browser.

The dataset is published in full: every clause with its three numbers and sources, every FAR and DFARS part the overhaul touched, the topics from cyber to flow-down, what is a deviation, what is proposed and what is final, and the clause list template. It reads labels only, and a note is a change to take to the contracting officer or counsel, never a ruling on a contract.
