How do DormantFile deadline reminders work?

By Ben Davies · Updated 28 September 2026

DormantFile sends email reminders before and after your dormant company filing deadlines. Reminders cover your accounts and confirmation statement deadlines, and each director's, LLP member's and PSC's identity verification date while they still need to verify. We also remind you about any Corporation Tax or partnership return deadline you add: once you add a CT600 period or an SA800 year, its statutory deadline joins the same ladder, on a subscription and on the free Watchdog tier alike, pausing only while a card payment is failing. Filing the return itself needs a subscription. HMRC's own letter is always definitive for Corporation Tax dates, and we never work out your CT600 periods for you. The goal is simple: you hear about each deadline early enough to act, because late filing penalties land on a company that did nothing all year just the same.

Reminder schedule

Reminders are sent at the following intervals relative to each deadline:

Before the deadline: 90 days, 30 days, 14 days, 7 days, 3 days, and 1 day before.

After the deadline (if still unfiled): 1 day, 7 days, 30 days, and 90 days overdue.

This gives you plenty of early warning, progressively more urgent nudges as the deadline approaches, and continued reminders if you miss it — because the penalty for late accounts moves into a higher band the longer you wait.

Grouped, never one email per company

If you have multiple companies, you will not receive a separate email for each one. Reminders that fall due on the same day arrive grouped: one email covers every company with an accounts or tax return reminder that day, and confirmation statement and director ID reminders are grouped the same way, each in an email of its own.

Controlling what you receive

DormantFile splits its email into four categories, each with its own toggle on your Settings page (or the no-login preferences link in any email footer):

• Deadline reminders — the accounts, confirmation statement and identity verification schedule above.
• Register & strike-off alerts — dissolution, strike-off and unexpected changes to your company's public record.
• Offers & upsells — adding another company, and nudges if you don't finish signing up.
• Product news — new features and occasional announcements.

Turning off deadline reminders turns off deadline emails only — alerts, offers and news are controlled separately. Account, billing, and filing-outcome emails (receipts, submission confirmations, rejection notices) always send regardless of these toggles, since they're about something you did, not a nudge about something you haven't.

You can also suppress reminders for individual filing periods if you want notifications for some companies but not others — for example, if a period was filed through another service and you are just waiting to mark it as complete.

Calendar feed as an alternative

If you prefer a visual overview over email, DormantFile also offers a calendar feed that puts your deadlines directly into Google Calendar, Outlook, or Apple Calendar. The calendar feed and email reminders work independently — use one or both.
