Everything DormantFile does for you
Purpose-built for dormant companies. Here's what's under the hood.
Smart setup
Add your company in seconds. We handle the rest automatically.
Companies House lookup
Enter your company number and we pull your name, incorporation date, accounting reference date, registered address, and SIC codes automatically.
Automatic gap detection
We fetch your full Companies House filing history and calculate every unfiled period since incorporation. Years behind? You’ll see exactly what needs filing.
Share capital extraction
If your company has issued shares, we pull the amount from your latest confirmation statement. It’s pre-filled — just confirm and move on.
Filing
Generate compliant documents and submit directly to HMRC and Companies House.
iXBRL document generation
We generate the iXBRL accounts and tax computation documents required by Companies House and HMRC. You never see the XML — it’s handled automatically.
Direct API submission
Your filings go through the same official HMRC GovTalk and Companies House Software Filing APIs that Xero and FreeAgent use.
Real-time status tracking
After submission, we poll HMRC and Companies House for your filing result. If it’s accepted, you’ll know within minutes. If there’s an issue, you’ll see exactly why.
Catch-up filing
File any outstanding period, not just the current one. If you’re years behind, work through them one at a time in a single sitting.
Mark as filed elsewhere
Filed accounts or a CT600 through your accountant or another service? Mark the period as done so it stops appearing in your outstanding list and reminders.
Submission confirmation
Before every filing, you’ll see a clear summary of exactly what’s being submitted, to which authority, and for which period. Nothing is sent until you confirm.
Monitoring
Never miss a deadline. We watch your filings around the clock.
Deadline intelligence
Reminders at 90, 30, 14, 7, 3, and 1 day before each filing is due. Overdue alerts at 1, 7, 30, and 90+ days after. One consolidated email per day, penalty amounts included.
Daily Companies House sync
Your company data is refreshed against Companies House every day. If your accounting reference date changes or a period is filed elsewhere, we detect it automatically.
External filing detection
Filed a period through your accountant or another tool? We detect it in your Companies House filing history and mark it as done — no manual cleanup.
Period suppression
Have a period you’re handling separately? Suppress it so it stops appearing in reminders and your needs-attention list.
Calendar feed
Subscribe to your filing deadlines in Google Calendar, Outlook, or any calendar app. Deadlines update automatically as you file.
Company activity timeline
See a chronological history of every event for each company — filings submitted, acceptances, rejections, and reminders sent.
Security & trust
Your credentials are handled with care. Here's how we keep them safe.
Credentials never stored
Your HMRC Government Gateway password is used once at submission and immediately discarded from memory. Never written to disk, never logged.
Filing audit trail
Every response from HMRC and Companies House is stored against your filing record — correlation IDs, timestamps, and full response payloads. Yours to reference if you ever need proof.
Printable filing receipts
View and print a confirmation receipt for every accepted filing. Includes your company details, period, submission reference, and IRmark.
Share filing confirmations
Copy a formatted filing summary to your clipboard in one click. Useful for sharing confirmation details with directors or clients.
Payments via Stripe
Card details are handled entirely by Stripe. We never see or store your payment information.
14-day refund guarantee
Full refund within 14 days if you haven’t submitted a filing. No questions.
Multi-company & agent filing
Managing multiple dormant companies? We built this for you.
Portfolio dashboard
All your companies in one view. Filter by needs-attention, recently filed, or issues. Search and sort as the list grows.
Consolidated reminders
One email per day covering every company’s upcoming and overdue deadlines. No email per company — just one summary.
CSV export
Download your full company list with filing statuses, deadlines, and period data as a CSV. Open in Excel or Google Sheets for your own records.
Agent filing mode
File CT600 returns on behalf of clients using your own HMRC Government Gateway credentials. The submission declares you as agent — your clients don’t need to share their login.
Scales to 100 companies
Manage up to 100 dormant companies from one account at 49p per company per year.
