Who Files Late? STOCK Act Deadline Compliance, Ranked

The STOCK Act requires members of Congress to report a securities transaction within 30 days of learning of it and no later than 45 days after it takes place. That deadline is the entire transparency mechanism: until the report is filed, nobody outside the member’s office knows the trade happened. The figures here compare each transaction’s trade date with the date its report was filed, and they count transactions made by a member’s spouse or dependent child, which are reported on the same forms.

House vs Senate

Coldpine’s House record goes back to January 2023 and its Senate record begins with reports filed in January 2026, so the two chambers are compared over the months both are covered. In reports filed from January 1, 2026 through October 29, 2026, the median transaction was reported 25 days after the trade in the House and 37 days after it in the Senate. 245 of 5,265 House transactions (4.7%) and 959 of 2,193 Senate transactions (43.7%) were reported more than 45 days after the trade date. The Senate share rests on a few large reports: without each chamber’s largest filer, the shares are 7.7% in the House and 17.4% in the Senate. The full comparison is in does the House or the Senate trade more stocks.

The latest filers, ranked

Members with at least 10 dated disclosures, ranked by the share filed past the 45-day deadline. “Median lag” is days from trade to disclosure; the deadline is 45.

The percentages do not show how long the longest gaps run. Among the 122 members with 10 or more dated transactions, the longest median belongs to Michael K. Simpson: 849 days from trade to report across 22 transactions. Across all members, 591 transactions on record as of October 29, 2026 were reported more than a year after the trade. A count of days describes the record and does not say why a report arrived when it did.

What a late report costs under the rules

A Periodic Transaction Report is due within 30 days of a member learning of a trade, and no later than 45 days after the trade itself. A report filed more than 30 days past its due date carries a $200 late filing fee, which the House and Senate ethics committees can waive. The fee is a flat amount: it does not change with the size of the trade or the number of transactions in the report.

Most of the record sits inside the deadline. As of October 29, 2026, 92.9% of the 29,229 dated transactions on record were reported within 45 days of the trade, and 43 of the 122 members with 10 or more dated transactions have never reported one past that mark.

The delay has a second-order effect on anyone reading the filings: the longer the lag, the staler the information is on arrival. We measured what stocks actually do during that quiet window in What Stocks Do Before Congress Discloses.

Methodology and honest caveats

Lag is disclosure date minus transaction date, both taken from the government filings. Transactions with no usable trade date, or with a gap outside a 0-to-1,000-day window, are left out (261 as of October 29, 2026). The record covers House reports filed since January 2023 and Senate reports filed since January 2026. Members are counted per person in the key numbers, so a member who appears under two spellings is counted once. The member table requires at least 10 dated disclosures. The party-level split, in both the transaction-weighted and member-weighted frames, is in Which Party Files Late?. How filings are parsed is set out in the methodology.
