SEC proposes option for semi-annual reporting

Posted on May 11, 2026 by Editor

Earlier this week the US Securities and Exchange Commission (SEC) proposed amendments that would allow Exchange Act reporting companies to elect, on an annual basis, to file semi-annual reports on a new Form 10-S in place of the three quarterly Forms 10-Q currently required. Companies that do not elect would continue to file 10-Qs. A 60-day public comment period will follow publication in the Federal Register.

The implications for users are significant. For companies that elect, two of the three interim Inline XBRL filings produced each year would disappear, reducing the cadence of tagged financial data, and the time-series granularity it supports, by two thirds. The Commission’s own economic analysis acknowledges this directly, noting that the documented benefits of XBRL tagging, including improved liquidity, lower cost of capital, more accurate analyst forecasts and enhanced artificial intelligence capabilities  “may be reduced as a whole given the lack of quarterly XBRL-tagged financial data from semi-annual and hybrid reporters.” Like others, we still need to really dig into the proposal, but on the face of it, it seems odd timing.

The case for reducing reporting frequency rests on compliance burden, but disclosure preparation costs are now falling rapidly as AI-assisted drafting, automated data aggregation and modern reporting platforms mature. At a moment when the volume of internal data available to companies has reached unprecedented levels, and when demand from investors, supervisors and AI-driven analytical tools for high-frequency, comparable, machine-readable disclosure is rising, the proposal seems unusual. Reducing the cadence of structured public reporting just as the tools to deliver it efficiently come of age warrants your attention.

XBRL International will be working with our colleagues at XBRL US to provide a formal response to the consultation, and we encourage others to do likewise.
