At what dollar threshold does a government contractor’s accounting practices become a federal compliance document? The answer determines whether your cost accounting methodology is a private business decision or a binding disclosure subject to DCAA audit, contracting officer approval, and potential noncompliance penalties.
Most small government contractors never file a CAS Disclosure Statement. Most do not need to. But the threshold is lower than many expect, and crossing it without recognizing the obligation creates a compliance gap between what the contractor practices and what the government expects to see documented. DCAA discovers this gap during the first post-threshold audit.
The CAS Disclosure Statement (CASB DS-1) is a formal, standardized description of a contractor’s cost accounting practices filed with the cognizant federal agency. It covers how the contractor classifies costs as direct or indirect, how indirect cost pools are structured, what allocation bases are used, and how the contractor treats specific cost elements like compensation, depreciation, and pension costs. Once filed, the Disclosure Statement becomes a binding commitment: the contractor must follow the disclosed practices consistently or face noncompliance findings.
Who Must File a CAS Disclosure Statement
The filing threshold for a CAS Disclosure Statement is triggered by contract value. A contractor must file a CASB DS-1 when it receives a single CAS-covered contract or subcontract of $50 million or more, or when the contractor’s net CAS-covered awards in the prior cost accounting period total $50 million or more [FAR 30.201-4; 48 CFR 9903.202-1]. The “net” calculation excludes sealed-bid fixed-price contracts awarded on price competition alone [48 CFR 9903.201-1]. The FY2026 NDAA (Sec. 1806) is reported to raise this threshold to $100 million for contracts awarded on or after June 30, 2026; verify the implementing DFARS rule before relying on this figure.
Contractors below the DS-1 filing threshold are “CAS-exempt” for Disclosure Statement purposes. They may still be subject to CAS requirements depending on contract value. Under pre-FY2026-NDAA rules, contractors holding any single contract over $2.5 million (but below $50 million) are subject to modified CAS coverage only [FAR 30.201-4(b)(1); 48 CFR 9903.201-2]. Modified coverage requires compliance with four CAS standards: CAS 401 (consistency in estimating), CAS 402 (consistency in allocating), CAS 405 (accounting for unallowable costs), and CAS 406 (cost accounting period). Contractors subject to full CAS coverage (single contract at or above the filing threshold) must comply with all CAS standards. The FY2026 NDAA (Sec. 1806) is reported to raise the per-contract CAS applicability threshold to $35 million; verify implementation before relying on this figure. The distinction matters: a contractor at $30 million in CAS-covered contracts may be subject to modified CAS standards without owing a DS-1 filing.
Educational institutions file a separate form (CASB DS-2) with different instructions and thresholds. This article addresses only the standard CASB DS-1 applicable to commercial contractors.
What the CAS Disclosure Statement Covers
The CASB DS-1 form contains eight major sections, each requiring detailed descriptions of the contractor’s cost accounting practices. DCAA reviews the completed form against the contractor’s actual books to verify consistency. A mismatch between the Disclosure Statement and actual practice triggers a noncompliance finding regardless of whether the actual practice is reasonable.
| DS-1 Section | What It Covers | Key Accounting Decisions Disclosed |
|---|---|---|
| Part I | Cover sheet and certification | Entity name, address, certifying official, effective date of disclosure |
| Part II | General information | Fiscal year, organizational structure, CAS-covered segments |
| Part III | Direct costs | Which costs are charged direct, labor distribution methods, material charging practices |
| Part IV | Direct vs. indirect | Criteria for classifying costs as direct or indirect, consistency rules |
| Part V | Indirect costs | Pool structure (fringe, overhead, G&A), allocation bases, home office allocations |
| Part VI | Depreciation and capitalization | Capitalization threshold, depreciation methods, asset lives |
| Part VII | Other costs | Pension, deferred compensation, insurance, IR&D/B&P |
| Part VIII | Consistency in practice | How changes in practice are identified and reported |
Each section forces the contractor to articulate decisions most firms make informally. What is your capitalization threshold? Which costs go to overhead vs. G&A? How do you allocate home office costs to segments? The Disclosure Statement converts these informal practices into auditable commitments.
Filing, Review, and Approval Process
The contractor submits the completed CASB DS-1 to the cognizant federal agency (typically the contracting officer at the agency with the largest dollar volume of CAS-covered contracts). DCAA reviews the Disclosure Statement for adequacy and compliance with applicable CAS standards. In practice, the review typically takes 60 to 120 days from submission, though no regulation prescribes a specific timeline.
DCAA’s adequacy review checks whether the Disclosure Statement is complete (all sections filled), internally consistent (Part III does not contradict Part V), and compliant with CAS requirements. An inadequate Disclosure Statement is returned for revision. An adequate but noncompliant statement triggers corrective action: the contractor must either change its practices to match a compliant methodology or demonstrate why the current practice satisfies the standard.
Once accepted, the Disclosure Statement is effective for all CAS-covered contracts. The contractor must follow the disclosed practices. Changing a practice without amending the Disclosure Statement is a noncompliance event subject to cost adjustments under FAR 52.230-6.
When Amendments Are Required
A contractor must amend its CAS Disclosure Statement before implementing any change in cost accounting practice [FAR 52.230-6]. “Change” means any alteration in a methodology, allocation base, pool structure, or cost classification previously disclosed. Examples triggering amendments: switching the G&A allocation base from total cost input to value-added, adding a new indirect cost pool, changing the capitalization threshold, or reclassifying a cost from direct to indirect.
The amendment process mirrors the original filing. Submit the revised DS-1 sections to the cognizant agency no less than 60 days before the change takes effect [FAR 52.230-6(b)]. DCAA reviews for adequacy and compliance. The contracting officer determines the cost impact of the change under FAR 52.230-6. If the change increases costs to the government, the contractor bears the increase. If it decreases costs, the government receives the benefit.
Contractors sometimes change practices without realizing an amendment is needed. A new CFO restructures the indirect rate pools for efficiency. The restructuring is sound accounting. But without a DS-1 amendment filed before the change, DCAA classifies it as a noncompliant cost accounting practice change, triggering cost adjustments on every CAS-covered contract.
Common CAS Disclosure Statement Mistakes
DCAA’s CAS compliance audits reveal patterns in how contractors fail the Disclosure Statement requirement. Four errors appear most frequently.
- Crossing the filing threshold without recognizing it. The contractor’s cumulative CAS-covered awards exceed the DS-1 trigger mid-year. Nobody tracks the cumulative total. DCAA discovers the gap during the next incurred cost submission review. The contractor must file retroactively and reconcile prior practices against the newly disclosed methodology.
- Disclosure Statement does not match actual practice. The DS-1 states G&A is allocated on total cost input. The actual books use a value-added base. The mismatch creates a noncompliance finding on every CAS-covered contract, regardless of which base is more appropriate.
- Practice changes without amendments. The contractor changes its capitalization threshold from $5,000 to $10,000 without amending the DS-1. Every asset between $5,000 and $10,000 purchased after the change is treated inconsistently with the Disclosure Statement. DCAA recalculates depreciation on every affected contract.
- Incomplete sections. The contractor leaves Part VII (pension and deferred compensation) blank because it has no pension plan. DCAA returns the form as inadequate. Even “not applicable” requires a response explaining why.
Preparing for the Disclosure Statement Threshold
Contractors approaching the CAS-covered filing threshold should prepare the DS-1 before crossing it, not after. The preparation process reveals accounting practice inconsistencies easier to fix before the practices become binding disclosures.
Start with a self-assessment. Document every cost classification decision currently in place: what goes direct, what goes indirect, which pools exist, what allocation bases are used, what the capitalization threshold is, how compensation is determined. Compare this documentation against the DS-1 form sections.
Gaps between current practice and what the DS-1 requires you to articulate are the areas needing attention.
In our experience reviewing contractor disclosures, the written accounting policies most contractors already maintain for DCAA cover 60 to 70% of DS-1 content. The remaining 30 to 40% typically involves pension and deferred compensation treatment (Part VII), home office allocation methods (Part V), and detailed depreciation methodology (Part VI). Work with a CPA experienced in CAS compliance to complete these sections accurately. An error in the DS-1 is more costly than an error in the books because it affects every CAS-covered contract simultaneously.
Frequently Asked Questions
What is a CAS Disclosure Statement?
The CASB DS-1 is a standardized form describing a contractor’s cost accounting practices: how costs are classified as direct or indirect, how indirect pools are structured, what allocation bases are used, and how specific cost elements (compensation, depreciation, pension) are treated. Once filed, it becomes a binding commitment audited by DCAA for consistency.
At what dollar amount must a contractor file a Disclosure Statement?
When a single CAS-covered contract or subcontract reaches $50 million, or when net CAS-covered awards in the prior period reach that same level [FAR 30.201-4; 48 CFR 9903.202-1]. The FY2026 NDAA (Sec. 1806) is reported to raise both triggers to $100 million for contracts awarded on or after June 30, 2026; confirm against the implementing DFARS rule before relying on this figure. Sealed-bid fixed-price contracts are excluded from the calculation. Most small business government contractors operate below this threshold.
What happens if a contractor changes practices without amending the DS-1?
DCAA classifies the change as a noncompliant cost accounting practice change. The contracting officer calculates the cost impact under FAR 52.230-6. If the change increased costs to the government, the contractor reimburses the difference on every affected CAS-covered contract. Filing the amendment at least 60 days before implementing the change prevents this exposure [FAR 52.230-6(b)].
Do CAS-exempt contractors need to worry about the Disclosure Statement?
Not until they approach the filing threshold. Contractors below it may still be subject to modified CAS coverage, which requires compliance with four standards (CAS 401, 402, 405, 406) on contracts over $2.5 million [FAR 30.201-4(b)(1); 48 CFR 9903.201-2], but they do not file a DS-1. The FY2026 NDAA (Sec. 1806) is reported to raise this modified-coverage threshold; verify the implementing rule. Track cumulative CAS-covered awards annually to avoid crossing the DS-1 filing threshold without preparation.
How long does DCAA take to review a Disclosure Statement?
In practice, 60 to 120 days from submission is a common range, though no regulation prescribes a specific review timeline. DCAA checks for completeness, internal consistency, and compliance with applicable CAS standards. An incomplete or internally inconsistent submission is returned for revision, restarting the clock. Submit a complete, CPA-reviewed DS-1 to avoid revision cycles.
Key Takeaways
- The CAS Disclosure Statement (CASB DS-1) is required when a single CAS-covered contract or cumulative net CAS-covered awards cross the $50 million filing threshold [FAR 30.201-4; 48 CFR 9903.202-1]. Most small GovCon firms never reach this threshold, but those approaching it must prepare before crossing.
- Once filed, the DS-1 is a binding commitment. Every cost accounting practice disclosed must be followed consistently. Changing a practice without amending the Disclosure Statement triggers noncompliance findings and cost adjustments on every CAS-covered contract under FAR 52.230-6.
- Contractors below the DS-1 filing threshold but over $2.5 million on a single contract are subject to modified CAS coverage, which requires compliance with four standards (CAS 401, 402, 405, 406) but does not require filing a DS-1 [48 CFR 9903.201-2; FAR 30.201-4(b)(1)]. Full CAS coverage (at or above the filing threshold) requires compliance with all CAS standards.
- In our experience, written accounting policies already maintained for DCAA cover 60 to 70% of DS-1 content. Prepare the DS-1 before crossing the threshold, not after. Work with a CPA experienced in CAS to complete the remaining sections accurately.
The Disclosure Statement formalizes what your books already do. The risk is not the filing itself but the gap between what the form says and what your system actually does.
