SEC Filing Deadlines by Filer Status: The Calendar
By Chad Hartman
Published · Last updated
Most explanations of SEC filing deadlines quietly assume every filing scales the same way: bigger company, faster deadline. That's true for exactly two filings — the 10-K and the 10-Q. It isn't true for the 8-K, Form 4, 13F, or Schedule 13D and 13G, all of which run on entirely different clocks that have nothing to do with the size of the company being reported on. Confusing the two systems is the single most common mistake in casual explanations of SEC filing timing.
This reference separates the two systems cleanly: what "filer status" actually means, which deadlines it controls, which deadlines it has no bearing on at all, what happens when a company misses one, and a proposed SEC rule change that could reshape the entire filer status framework in the near term. For what each of these filings actually contains, see our complete guide to SEC filing types for investors.

What Determines a Company's Filer Status?
Filer status is set by public float — the aggregate market value of a company's voting and non-voting common equity held by non-affiliates, measured as of the last business day of its most recently completed second fiscal quarter. A large accelerated filer has public float of $700 million or more. An accelerated filer has public float of at least $75 million but under $700 million. A non-accelerated filer has public float under $75 million, or simply hasn't yet met the additional tests required to be classified as accelerated. Those tests require at least one annual report already filed, and at least 12 months subject to Exchange Act reporting. Every newly public company starts out non-accelerated by default, regardless of how large its float is at IPO.
The thresholds aren't perfectly symmetric. A company doesn't exit accelerated filer status the moment its float dips below $75 million — it has to fall below $60 million (80% of the entrance threshold) before it exits down to non-accelerated. The same hysteresis applies at the top: a large accelerated filer doesn't drop a tier until its float falls below $560 million. That gap exists so a company hovering right at a threshold isn't flipping filer status, and the deadlines that come with it, every single year.
One category that's easy to conflate with filer status but isn't the same thing: smaller reporting company (SRC) status. SRC eligibility runs on a separate test — public float under $250 million, or float under $700 million combined with annual revenue under $100 million. It unlocks scaled disclosure accommodations instead, like reduced executive compensation tables and, in some cases, relief from the auditor's internal-control attestation. It does not change a company's 10-K or 10-Q deadline. A company can be both an accelerated filer and an SRC at the same time, filing on the accelerated filer's deadline while using the SRC's lighter disclosure rules.
10-K and 10-Q Deadlines by Filer Status
This is the one part of the SEC filing calendar where company size genuinely sets the clock.
| Filer Status | Public Float | 10-K Deadline | 10-Q Deadline |
|---|---|---|---|
| Large Accelerated Filer | $700 million or more | 60 days after fiscal year-end | 40 days after quarter-end |
| Accelerated Filer | $75 million to $700 million | 75 days after fiscal year-end | 40 days after quarter-end |
| Non-Accelerated Filer | Under $75 million | 90 days after fiscal year-end | 45 days after quarter-end |
The detail that trips up the most casual references: the 10-Q's 40-day deadline applies to accelerated filers, not just large accelerated ones. Accelerated and large accelerated filers share the same 40-day quarterly window; only non-accelerated filers get the extra five days, to 45. The gap between filer statuses only really shows up in the 10-K, where it spans a full 30 days between the fastest and slowest tier. For a complete walkthrough of what else separates these two filings beyond timing, see our 10-K vs. 10-Q guide.
When Is a Company's Next 10-K or 10-Q Due? A Worked Example
The table above is the rule. Applying it to a specific company takes two inputs: the fiscal year-end printed on the cover of its last filing, and the filer status box it checked on that same cover page. Everything else is counting days forward.
Take the most common case — a company whose fiscal year ends December 31. Counting forward from the period end using the deadlines above:
| Filing | Period ends | Large accelerated (60 / 40 days) | Accelerated (75 / 40 days) | Non-accelerated (90 / 45 days) |
|---|---|---|---|---|
| 10-K | December 31 | March 1 | March 16 | March 31 |
| Q1 10-Q | March 31 | May 10 | May 10 | May 15 |
| Q2 10-Q | June 30 | August 9 | August 9 | August 14 |
| Q3 10-Q | September 30 | November 9 | November 9 | November 14 |
Two things fall out of the arithmetic that the deadline table alone doesn't make obvious. The first is that the accelerated and large accelerated columns are identical for all three quarters and differ only once a year, on the annual report — the 30-day spread between the fastest and slowest 10-K tier is the entire practical difference between filer statuses for most of the calendar. The second is that a leap year moves the three 10-K dates one day earlier, to February 29, March 15, and March 30, because the count runs on days rather than months. The quarterly dates are unaffected, since each quarter-end that anchors those counts falls after February.
A company with a non-December fiscal year-end runs the same arithmetic off its own dates. There is no separate schedule for off-cycle filers; the day counts are the same, only the starting point moves.
8-K, Form 4, 13F, and 13D/13G Deadlines (Not Set by Filer Status)
Every other filing an investor regularly reads runs on a clock triggered by something other than the subject company's size.
| Filing | Deadline | What Actually Triggers It |
|---|---|---|
| 8-K | 4 business days (most items) | The reportable event itself — same window for every registrant |
| Form 4 | 2 business days | The insider's transaction date — same window for every reporting person |
| 13F | 45 days after calendar quarter-end | The institutional manager's own $100 million-plus threshold, not the size of any company it holds |
| Schedule 13D | 5 business days after crossing 5% | The investor's own stake crossing the threshold, not the issuer's filer status |
| Schedule 13G | 5 business days (passive filers) or 45 days after quarter-end (qualified institutional and exempt investors) | The filer's own investor category |
An 8-K is event-triggered: most items must be filed within 4 business days of whatever happened, regardless of whether the company is a large accelerated filer or the smallest non-accelerated one on EDGAR. A Form 4 works the same way from the insider's side — the 2-business-day clock starts on the transaction date, not on anything about the company's size. Form 13F deadlines are set by the reporting manager crossing $100 million in assets under management, a completely separate regulatory test from any company's public float. And Schedule 13D and 13G, which disclose an investor crossing 5% ownership of a company, run on deadlines set by the investor's own category — activist intent versus passive, qualified institutional or not. Never by the target company's filer status. Our Schedule 13D vs. 13G guide covers that investor-side deadline structure in full.
What Happens If a Company Misses Its Deadline? (Form 12b-25)
A deadline that passes without a filing is not automatically a delinquency. A company that can't complete its 10-K or 10-Q on time files a Form 12b-25 — a notification of late filing, which appears on EDGAR as an NT 10-K or an NT 10-Q depending on which report is late. It is the filing you should look for first when a periodic report you expected hasn't appeared.
The notification is itself a disclosure, and it is usually the most informative document a late filer produces. It states which report is late and why, in the company's own words. That explanation is what distinguishes a scheduling problem from a substantive one: an auditor still completing procedures, a recent acquisition whose accounting isn't closed, an unresolved accounting question, or an internal investigation are very different signals, and the company has to pick one and put it in writing. The notification also carries the company's own statement of whether it expects a significant change in results from the prior period.
Filing a 12b-25 gives the company a short additional window to complete the report. If the report lands inside that window, the filing is treated as having been made on time; if it doesn't, the company is a delinquent filer, with the reporting and eligibility consequences that follow. So the practical check on any missed date is a two-step one: look for the notification, then look for the actual report behind it. A 12b-25 with no report following it is a materially different situation from a 12b-25 followed by a complete filing days later.
The SEC's Proposed Filer Status Overhaul (May 2026)
The filer status framework described above isn't necessarily permanent. On May 19, 2026, the SEC proposed a significant overhaul that would collapse the current multi-tier system into just two categories: large accelerated filer and non-accelerated filer, eliminating the accelerated filer and smaller reporting company categories entirely. The proposal would also raise the large accelerated filer threshold from $700 million to $2 billion in public float. It would also create a new "small non-accelerated filer" sub-category — companies with $35 million or less in total assets — eligible for extended deadlines of 120 days for the 10-K and 50 days for the 10-Q.
The public comment period on this proposal closed July 20, 2026, and as of this writing the SEC has not adopted final rules. If adopted as proposed, the table above would need a significant rewrite: the SEC's own estimate is that the expanded non-accelerated filer category would cover roughly 81% of domestic registrants, up from about 52% today. Nothing in this filer status framework changes until the SEC finalizes a rule, but it's worth watching if you track filing timing across a broad universe of names.
How to Check a Company's Filer Status
A company's filer status isn't something you have to calculate yourself. Every 10-K and 10-Q cover page carries a checkbox section — large accelerated filer, accelerated filer, non-accelerated filer, smaller reporting company, emerging growth company — where the company self-identifies its own status for that specific filing. GeminIQ's Financial Statements feature pulls the full as-filed document, cover page included.
If you check cover pages routinely across a list of names, this is the one task where a filing-retrieval tool earns its keep — how BamSEC handles it is a reasonable point of comparison, since the checkbox lives in the document itself and never in a normalized financial database. Before you assume a filing missed its deadline, check the box the company actually checked — the filer status on the cover page tells you which clock applied, before you draw any conclusion from the calendar.
Frequently Asked Questions
What is the deadline for a 10-K filing?
It depends on filer status: 60 days after fiscal year-end for a large accelerated filer, 75 days for an accelerated filer, and 90 days for a non-accelerated filer.
Do accelerated filers and large accelerated filers have the same 10-Q deadline?
Yes. Both file the 10-Q within 40 days of quarter-end. Only non-accelerated filers get the longer 45-day window — the 10-Q deadline only has two tiers, not three.
Does an 8-K deadline change based on company size?
No. Most 8-K items must be filed within 4 business days of the triggering event regardless of whether the company is a large accelerated filer or a non-accelerated one. The clock starts on the event, not on the company's public float.
Is smaller reporting company status the same as non-accelerated filer status?
No. They're determined by different tests and serve different purposes. Smaller reporting company status unlocks scaled disclosure accommodations; it doesn't by itself change a company's 10-K or 10-Q deadline, which is set separately by large accelerated, accelerated, or non-accelerated status.
