Step 1. Your fiscal year and filer status

Nothing is sent to a server. The calendar is computed in your browser.

Assumes fiscal quarters end 3, 6, and 9 months after your fiscal year end, and no transition period from a fiscal-year change. Horizon: today through roughly 15 months out.

Not sure of your filer status?

Status is driven mainly by public float measured at your most recent second-fiscal-quarter end. Your last 10-K cover page shows the box you checked. The thresholds:

StatusThreshold10-K10-Q
Large Accelerated FilerPublic float ≥ $700M60 days40 days
Accelerated FilerFloat ≥ $75M and < $700M (plus other conditions, incl. the SRC revenue test)75 days40 days
Non-Accelerated FilerFloat < $75M90 days45 days
Smaller Reporting CompanyFloat < $250M, or revenue < $100M and float < $700M90 days*45 days*

*An SRC can also be an Accelerated Filer (the categories overlap). If your 10-K cover checks both SRC and Accelerated Filer, use the Accelerated deadlines. Deadlines follow accelerated-filer status, not SRC status.

Countdown

DEF 14A rows are the 120-day marker under General Instruction G(3) of Form 10-K: they apply only if Part III of your 10-K incorporates information from the proxy statement by reference. Form NT must itself be filed no later than one business day after the original due date. 8-K deadlines (4 business days after most triggering events) are event-driven and cannot be pre-scheduled.

The .ics file adds an all-day event for each deadline with reminders 14 days and 3 days before. Works with Outlook, Google Calendar, and Apple Calendar.

Working backward from your next filing

These are suggested working-backward milestones (typical practice), not SEC rules. Set them with your auditor and audit committee; review timelines vary with complexity and first-year audits run longer.

Optional. Reminders in your inbox

Questions we get asked

Rule names cited so you can verify each one with counsel.

When is my 10-K due?
It depends on your filer status: 60 days after fiscal year end for a Large Accelerated Filer, 75 for an Accelerated Filer, 90 for a Non-Accelerated Filer or SRC (Exchange Act Rules 13a-1 / 15d-1; General Instruction A of Form 10-K). If that date lands on a weekend or federal holiday, it rolls to the next business day.
What if the deadline falls on a weekend or holiday?
Exchange Act Rule 0-3(a): a filing due on a Saturday, Sunday, or federal holiday may be filed on the next business day and still be timely. The calendar above applies that roll automatically, using the US federal holiday schedule for 2026 through 2028.
What does Form NT / Rule 12b-25 do?
If you can't file on time, filing Form 12b-25 (NT 10-K or NT 10-Q) no later than one business day after the due date gives an automatic extension: 15 calendar days for a 10-K, 5 calendar days for a 10-Q. You must represent that the report couldn't be filed without unreasonable effort or expense, and you must actually file within the window for the report to be deemed timely. The NT itself is a public filing; the market reads it.
What happens if we file late?
The immediate costs: loss of Form S-3 eligibility for 12 months, exchange listing deficiency notices, and Rule 144 becomes unavailable to your holders while you're not current, which can freeze insider and PIPE-investor sales. It also complicates any financing in progress. We wrote up the full consequences and the recovery playbook in our late-filing guide.
How do I know my filer status?
Check the cover page of your most recent 10-K; the box you checked is your status. It's driven mainly by public float measured at your most recent second-fiscal-quarter end: Large Accelerated at $700M+, Accelerated at $75M to under $700M (plus other conditions), Non-Accelerated under $75M. SRC status (float under $250M, or revenue under $100M with float under $700M) affects disclosure scaling, but your deadlines follow your accelerated-filer status. Status changes are measured once a year, so a mid-year float move doesn't change this quarter's deadline.
Does this cover 8-Ks and other forms?
No. Form 8-K is due 4 business days after the triggering event (for most items), so it can't be put on a calendar in advance. Section 16 forms, 13D/G amendments, and registration statements are also event-driven. This calendar covers the periodic filings you can plan for: 10-K, 10-Q, and the DEF 14A 120-day marker.
