Truth in Negotiations Act (TINA) — Cost or Pricing Data Requirements
The Truth in Negotiations Act (10 U.S.C. §§ 3702–3708) requires contractors and subcontractors to submit certified cost or pricing data — current, accurate, and complete information about their costs — before the government agrees to a contract price for acquisitions exceeding $2 million. When the government negotiates a contract price (as opposed to awarding based on competition), it needs to know what the contractor's actual costs are to negotiate fairly. TINA ensures the government isn't negotiating blind by requiring contractors to open their books. If a contractor submits defective data — costs that are inaccurate, incomplete, or not current — and the government overpays as a result, the government is entitled to a price reduction plus interest on the overpayment, and the contractor may face penalties. TINA is one of the most important protections against overcharging on sole-source and negotiated defense contracts, where the absence of competitive pricing makes cost transparency essential.

Legal Authority
- 10 U.S.C. § 3702 — Required cost or pricing data and certification (contractors must submit certified cost or pricing data for prime contracts and modifications over $2 million; subcontractors must comply at the same threshold; data must be "accurate, complete, and current" as of the date of price agreement)
- 10 U.S.C. § 3703 — Exceptions (no cost or pricing data required when price is based on adequate price competition, established catalog/market prices, prices set by law/regulation, or when the agency head grants a waiver)
- 10 U.S.C. § 3705 — Submission of other information (when certified data aren't required, the contracting officer may still require "information other than certified cost or pricing data" to evaluate price reasonableness)
- 10 U.S.C. § 3706 — Price reductions for defective cost or pricing data (contracts must include a clause allowing the government to reduce the price if the data were inaccurate, incomplete, or not current, and the defective data caused the government to pay more than it should have)
- 10 U.S.C. § 3707 — Interest and penalties (contractor must pay interest on overpayments from the date of overpayment; additional penalties may apply under 10 U.S.C. § 3802)
- 10 U.S.C. § 3708 — Right to examine contractor records (government may audit contractor records to verify cost or pricing data)
How It Works
TINA defines "cost or pricing data" specifically: all facts that, as of the date of price agreement, prudent buyers and sellers would reasonably expect to affect price negotiations significantly — vendor quotations, nonrecurring costs, pending make-or-buy decisions, historical cost data, unit cost data for current orders, and anything else affecting expected costs. The key word is "current": the data must reflect the most recent information available at agreement. When submitting this data, the contractor (or applicable subcontractor) must sign a certificate stating the data are "accurate, complete, and current" as of the certification date. That certification creates legal liability — it's the basis for a defective pricing claim if the data turn out to be wrong. If the government later discovers that certified data were defective — inaccurate, incomplete, or not current — and the defect resulted in a higher price, the government is entitled to a price adjustment equal to the overpayment plus interest. A contractor that certified a $100/unit component cost while already holding a $80/unit vendor quote faces a $20-per-unit reduction in contract price; DCAA and DCMA conduct defective pricing audits specifically to surface these discrepancies.
TINA has important exceptions — it applies only where the government lacks other means of ensuring fair pricing. The most significant is adequate price competition: when multiple companies compete and the market sets the price, cost data aren't needed. Other exceptions cover established catalog or market prices for commercial items (published prices available to the general public), prices set by law or regulation (utility rates), and waivers granted by the agency head when obtaining data is impractical. Even where the full TINA certification isn't required — competitive acquisitions, commercial items — contracting officers can still request "other than certified cost or pricing data" (informally called "other cost or pricing data"): pricing information sufficient to evaluate whether the proposed price is fair and reasonable, without the formal certification and its associated defective pricing liability. This intermediate category gives the government pricing visibility on commercial and competitive procurements without the compliance burden of full TINA.
How It Affects You
If you're a defense contractor with sole-source or negotiated contracts over $2 million, TINA compliance is one of your most significant legal exposures. The certification you sign — that your cost or pricing data are "accurate, complete, and current" as of the date of price agreement — creates direct liability if data later prove defective. The most common pitfall: receiving a lower vendor quote after your proposal was submitted but before signing the price agreement, then not disclosing it. If DCAA's defective pricing audit finds that you had a $15/unit vendor quote at the time you certified costs showing $22/unit, the government can demand a price adjustment on every unit in the contract, plus interest accruing from the date of overpayment. On a 1,000-unit contract, that's $7,000 per unit × 1,000 = $7 million in price reductions, plus potential False Claims Act exposure (treble damages plus $27,000+ per false claim). Protect yourself by implementing a data cutoff date procedure — designate someone to sweep for late-breaking cost data (vendor quotes, make-or-buy decisions, scrap rates) within 30 days before signing. Know your exceptions: if your contract qualifies as a commercial item or is awarded based on adequate price competition, TINA's certification requirement doesn't apply — but document that determination carefully, because DCAA will challenge commercial item claims on major programs.
If you're a subcontractor on a prime contract, TINA's flow-down provision means your $2 million subcontract carries the same obligations as the prime contract. The prime contractor is required by FAR 52.215-12 to include a TINA clause in your subcontract, and you must submit certified cost or pricing data to the prime, who passes it to the government. A defective pricing finding at the subcontract level ripples up: the government can reduce the prime's price, and the prime will seek to recover that reduction from you under the subcontract clause. This liability can significantly exceed your subcontract profit margin. If you're bidding sole-source subcontracts over $2 million, ensure your pricing organization understands TINA requirements — and check whether you qualify for commercial item treatment (which the prime's contracting officer can certify) before assuming TINA applies. The National Defense Industrial Association (NDIA) at ndia.org publishes guidance on commercial item determinations and TINA compliance for subcontractors.
If you're a government contracting officer or program manager, TINA is your primary tool for ensuring fair pricing when competition can't do the job. Before waiving certified cost data requirements, be rigorous about the exception analysis: "adequate price competition" requires at least two responsible offerors submitting responsive offers, with award to the low offeror — a single competitive offer doesn't qualify. After receiving certified cost data, your obligation isn't passive: FAR 15.403-4 requires you to analyze the data and document your price negotiation memorandum showing how certified costs informed the negotiated price. If you agree to a price above the government estimate without adequately using the certified data, you may have given away the protective value of TINA. Document the use of — or reasons for deviating from — submitted cost data. Request DCAA audit assistance for contracts over $100 million; for contracts in the $2–100 million range, conduct your own price analysis using the submitted data.
If you're a taxpayer or oversight professional tracking defense procurement, TINA is why defective pricing recoveries exist. DCAA audits identify cost overcharges on sole-source defense contracts — and the recoveries are real: DCAA's reports to Congress show hundreds of millions in questioned costs annually from defective pricing findings. The GAO's High Risk List has included DoD contract management for years, with sole-source pricing transparency as a recurring concern. When you see reporting on defense contractor overcharges, TINA is often the legal mechanism through which the government recovers funds — the contractor certified costs that were inaccurate, the government overpaid, and DCAA's audit exposed the gap. For the current scale of sole-source defense contracting, see DoD's Electronic Document Access (EDA) system at eda.ogden.disa.mil for public contract data, and GAO.gov/reports for audit findings on defense pricing.
State Variations
TINA applies to federal contracts (primarily defense):
- State procurement laws generally do not have TINA equivalents — state contracting relies more on competition and price analysis
- State auditors may review contractor costs on state contracts, but without the formal TINA certification framework
- Federal civilian agencies use the same TINA requirements through the FAR
Implementing Regulations
- 48 CFR 15.4 — FAR Subpart 15.4 (Contract Pricing) — the primary TINA implementation rule, covering certified cost or pricing data requirements, thresholds, exceptions, defective pricing remedies, and price reductions
- 48 CFR 52.215-10 through 52.215-15 — Standard FAR contract clauses implementing TINA requirements, including price reduction for defective cost or pricing data and requirements for submission of certified data
- 48 CFR 215.4 — DFARS Subpart 215.4 — DoD-specific contract pricing requirements with additional TINA guidance for defense acquisitions, including thresholds and audit procedures
Pending Legislation
No standalone TINA reform bills have been introduced in the 119th Congress. Cost or pricing data requirements appear in defense acquisition reform — see Defense Acquisition Reform and Federal Procurement & Contracting.
Recent Developments
The $2 million threshold has been adjusted over time (originally $100,000, then $500,000, then $750,000, now $2M) to reduce the compliance burden on smaller contracts. The recodification of defense procurement statutes (moving TINA from 10 U.S.C. § 2306a to §§ 3702–3708) reorganized but didn't substantively change the law. DCAA has increased its focus on defective pricing audits, particularly for large sole-source defense programs. The growing use of commercial item determinations to avoid TINA requirements has drawn GAO and IG scrutiny — some contractors have been found to inappropriately claim commercial item status to avoid cost disclosure.
