What Does the STOCK Act Do? Coverage, Disclosures, and Penalties

The Stop Trading on Congressional Knowledge Act, known as the STOCK Act, does two main things: it makes clear that federal officials can be prosecuted for insider trading when they buy or sell securities based on nonpublic government information, and it requires those officials to publicly report their securities transactions within tight deadlines. Signed as Public Law 112-105 in April 2012, the law also establishes a formal duty of trust between officials and the public, closing a longstanding question about whether congressional insider trading was actually illegal.¹

The Ban on Trading With Inside Information

Before 2012, there was a genuine legal question about whether a member of Congress could be charged with insider trading at all. The securities laws had been written with corporate insiders in mind, and no legislator had ever been successfully prosecuted for trading on information learned on the job. The STOCK Act closes that gap by stating directly that members of Congress and congressional employees “are not exempt from the insider trading prohibitions arising under the securities laws, including section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5 thereunder.”¹

The law then adds a second piece that matters just as much. It says every member of Congress and congressional employee “owes a duty arising from a relationship of trust and confidence to the Congress, the United States Government, and the citizens of the United States” with respect to material, nonpublic information obtained through their position.¹ Insider trading cases generally require a breach of some fiduciary duty; without a statutory duty like this one, prosecutors would have to argue that a general obligation existed, and courts might disagree.

The prohibition covers tipping as well. An official who passes nonpublic information to a friend or relative who then trades on it can face liability alongside the trader.

Who the Law Covers

Coverage runs across all three branches of the federal government. In Congress, every Senator, Representative, Delegate, and the Resident Commissioner from Puerto Rico is included, along with congressional employees whose pay is disbursed by the Secretary of the Senate or the Chief Administrative Officer of the House. In the executive branch, the President, Vice President, and federal employees broadly are covered, including U.S. Postal Service workers. Judicial officers and judicial employees fall under the Act too.

Not every covered employee faces the same paperwork. In the Senate, senior staff earning $151,661 or more in calendar year 2026 file the same periodic transaction disclosures as Senators themselves.² Lower-level employees are still bound by the trading ban but may not face the same transaction-level reporting.

Disclosure of Trades

The most visible thing the STOCK Act does day to day is force officials to disclose their trades. Covered filers must submit a Periodic Transaction Report, or PTR, whenever they, their spouse, or a dependent child buys, sells, or exchanges stocks, bonds, commodity futures, or other securities in a transaction over $1,000.³

Each report identifies the date of the transaction, the security involved, and whether it was a purchase, sale, or exchange. The filing deadline is the earlier of two dates: 30 days after the filer learns of the transaction, or 45 days after it took place.³ The 30-day clock matters when a broker or advisor handles a trade for a spouse. Even if the filer never authorized the trade personally, the deadline starts running the day they find out.

Family accounts are not a loophole. Trades by a spouse or dependent child require the same PTR, even when an investment advisor placed the order, and even when the transaction occurred inside a 401(k), IRA, variable annuity, or 529 college savings plan.³ Transfers strictly between the filer, spouse, and dependent children do not require a report.

A filer who cannot meet a deadline can request an extension from their agency’s Designated Agency Ethics Official. Extensions require good cause and cannot add up to more than 90 calendar days across all grants.⁴

The Blind Trust Alternative

An official who wants to avoid conflicts and skip transaction-by-transaction reporting can put investments in a qualified blind trust. The tradeoff is real. The trustee, who must be a financial institution, attorney, certified public accountant, broker, or investment advisor with no personal or business tie to the official, takes full control and stops communicating about holdings. Assets going into the trust must be free of any restrictions on sale, and the supervising ethics office has to approve the arrangement.⁵ The official still reports the category of income the trust generates, but no longer knows what it holds. Few members of Congress have used this route; setup and management costs are high, and giving up control is unattractive.

Where the Public Can See the Filings

The Senate publishes filings through the Electronic Financial Disclosure Search at efdsearch.senate.gov, and the House releases reports through the Office of the Clerk.² Both allow any member of the public to look up an official and view their transaction reports. The systems make individual lookup straightforward, though they are not designed for large-scale downloading and pattern analysis of the sort watchdog groups tend to want.

Penalties

Two very different penalty tracks run alongside each other under the Act.

Late or Missed Disclosures

Filing a PTR late triggers a $200 fee. The fee applies once per late report, not per transaction, so several missed trades in the same period still add up to $200. Agencies can waive the fee for extraordinary circumstances, but an intentional failure to file cannot be waived.⁶ The House and Senate ethics committees oversee compliance for their members and staff and can issue reprimands or recommend further discipline.

Actual Insider Trading

Trading on material nonpublic information carries far heavier consequences. Under the Securities Exchange Act, a willful violation can bring a fine of up to $5 million for an individual and up to 20 years in federal prison.⁷ On the civil side, the SEC can seek a penalty of up to three times the profit gained or loss avoided.⁸ Both the Department of Justice and the SEC can bring cases.

Why the Act Has Rarely Been Used

On paper the law has real force. In practice, no sitting member of Congress has been criminally prosecuted for insider trading under the STOCK Act since it passed. Dozens of members from both parties have been flagged for filing PTRs late, but the usual result is the $200 fee, and ethics officials frequently waive it.

Two things drive the gap. Insider trading cases require proof that the official held specific material nonpublic information and traded on it, and suspicious timing by itself does not clear that bar. And the $200 late-filing penalty is small next to trades that sometimes run into six or seven figures, so the financial pressure to file on time is weak. Independent databases run by watchdog groups and news outlets have become the practical accountability tool, sometimes surfacing patterns that official channels do not pursue.

Proposals to Go Further

Frustration with enforcement has driven proposals to move past disclosure and simply prohibit members of Congress from owning individual stocks. In the 119th Congress, the Committee on House Administration introduced legislation in January 2026 that would bar members, their spouses, and their dependent children from purchasing publicly traded securities, require public notice of any stock sale between 7 and 14 days before it occurs, and impose a penalty of $2,000 or 10 percent of the transaction value (whichever is greater) plus any net gain.⁹ Similar bills include the End Congressional Stock Trading Act (H.R. 1908) and the Ban Congressional Stock Trading Act (S. 1879).¹⁰ As of early 2026, none of these bills has moved beyond committee.
