How to set up UK company filing reminders (step by step)
This walkthrough matches the three steps on the filing reminders tool itself: find your company, check due dates, subscribe. For fees, penalties, and tax context, read the full guide first if you like — this page is about doing it once, correctly.

Before you start
Have ready: your company number (best) or enough of your registered name to pick the right hit from search, and an email address you check regularly. Optional: one or two tax deadlines from an HMRC letter, your online tax account, or your accountant (for example Corporation Tax payment or VAT return).
Step 1 — Find your company
Open UK company filing reminders. Either:
- Paste your company number (often eight digits from Companies House search), then use Show my due dates, or
- Use Search by company name, pick the correct entity from the list, and let the tool fill the number for you.
If you have several similar names, open the register in another tab and confirm the registered office and company number before you lock in the wrong Ltd.
Step 2 — Check the dates
After a successful lookup you should see confirmation statement and annual accounts due dates as held on the public register. Read them slowly: if something looks impossible compared to what you filed last year, stop and verify on GOV.UK or with your accountant before you trust reminders alone.
Optional tax fields: if you want the same email channel for tax, type up to two dates you already trust — for example “Corporation Tax pay by” and “VAT return due”. The tool does not pull these from HMRC; you are copying what you already know into the form.
Step 3 — Subscribe and confirm
Enter your email, choose how far ahead you want the first nudge, and submit. You will receive a confirmation link. Reminders do not start until you click that link — so check spam if nothing arrives, and use an inbox you control.
After confirmation, you should get emails ahead of each due date you are tracking (register dates plus any optional tax dates you added). When a reminder arrives, your job is still to file or brief your accountant through the proper channel.
If something goes wrong
- No dates after lookup — double-check the company number, or try name search again.
- No reminder emails — confirm you clicked the email confirmation link; check junk; make sure you chose a sensible notice period.
- Dates changed after a filing — run the lookup again later; the register updates when Companies House processes filings.
