The SEC is unambiguous on one point: there are no extensions for Form 13F. If you call or write to explain that your filing will be late, the answer is no. The deadline is 45 days after quarter-end, and that deadline does not move.
For compliance officers managing multiple obligations, that rigidity matters. And based on recent enforcement patterns, the SEC is paying closer attention to 13F delinquencies than many RIAs realize.
What the Penalties Actually Look Like
In September 2024, the SEC charged 34 reporting persons — firms and individuals — for late and missing Form 13F and Form 13H filings. The settlements totaled $7.2 million in penalties. Individual penalty amounts for Form 13F violations ranged from $175,000 to $525,000 per firm, with larger penalties tied to larger AUM. A separate 2024 sweep charged 11 institutional investment managers with failing to file Form 13F entirely — in some cases for years of sustained non-filing. Nine of those firms paid a combined $3.4 million.
The statutory maximum penalty is $750,000 per violation. For firms that both missed filings and were repeatedly late, penalties compounded.
Why Some Firms Don't Know They're Required to File
The $100 million threshold that triggers 13F obligations was set in 1975 and has never been adjusted for inflation. As AUM has grown across the industry — and as ETFs have become a primary vehicle for discretionary management — firms that wouldn't have historically crossed the threshold now do. Many are unaware of the obligation until an SEC exam flags it.
The threshold is evaluated monthly. If your firm exceeds $100 million in designated 13F securities on the last trading day of any month during a calendar year, you are required to file four Form 13F reports for that year — even if your AUM drops back below $100 million in subsequent months. Many newly obligated filers miss their first filing because they don't realize the obligation has been triggered.
The Self-Reporting Exception
In the September 2024 enforcement sweep, two firms escaped penalties entirely because they self-reported their delinquencies to the SEC before being contacted by enforcement staff. Self-reporting is not a guarantee of leniency, but the SEC has consistently signaled that voluntary disclosure and cooperation materially reduce enforcement risk. If your firm has missed one or more 13F filings, the right move is to file all delinquent reports immediately and consult legal counsel about voluntary disclosure — before the SEC finds the gap on its own.
What to Do If You're Already Late
File as soon as possible. The SEC's guidance is clear that late filers should submit immediately rather than wait for the next filing cycle. A filing submitted one day late is meaningfully different in enforcement risk than a filing that remains missing for a full quarter or multiple years. Sustained non-filing is what draws the largest penalties.
How to Protect Your Firm Going Forward
The firms caught in enforcement sweeps typically shared common patterns: no internal calendar tracking the 45-day deadline, no designated owner for the 13F workflow, and no redundancy if the responsible compliance officer was unavailable. A dedicated external filing service eliminates all three failure modes.
If your firm is approaching the $100 million threshold or has recently crossed it, contact File13F to confirm your filing obligation and get your process right from the start.
