Company Appears Twice or Shows Overdue After Filing
If the same company appears twice in your TinyTax dashboard, or if a company shows as overdue even though you have already filed, a duplicate company entry is usually the cause.
Why Does a Company Appear Twice?
This happens when the same company is added to your TinyTax account more than once, creating two separate entries with the same Companies House number.
The most common cause is adding the company again after it was archived, or simply adding it a second time by mistake. Each entry tracks its own filing history independently, so filings made under the original entry will not appear in the duplicate — and the duplicate will show outstanding obligations as if nothing has been filed.
How to Fix It — Archive the Duplicate
- Go to your Dashboard
- Click the Companies tab
- Find the duplicate entry — it will typically have no accepted filings, or show overdue items for periods you have already filed under the other entry
- Click Archive next to the duplicate
- Confirm — the duplicate disappears from your active view
Why Does the Dashboard Show Overdue After I Have Filed?
If you filed under one company entry and the duplicate is still visible, the dashboard will show the duplicate's obligations as overdue — even though the filings were accepted under the other entry. Archiving the duplicate resolves this.
A separate cause: if you have informed HMRC that your company is dormant but have not yet filed a dormant CT600 for the most recent period, TinyTax will still show the CT600 as outstanding. You can either file a dormant return through TinyTax (straightforward for zero-income companies) or use the CT600 Filed Elsewhere option from the filing button if you have handled it directly with HMRC.
Common Questions
Which entry should I archive?
Archive the duplicate — the one without accepted filings. If both entries have filings, compare the submission histories in the details drawer (click the arrow → on each row) and archive whichever is the newer, less-complete entry.
Will archiving affect my accepted filings?
No. Archiving only hides the entry from view. If the duplicate has no accepted filings, nothing is lost. Your real company entry and all its data remain completely intact.
The overdue notice is still showing after archiving
If an overdue notice persists after archiving the duplicate, check whether you have an unfiled CT600 for the most recent period under your main company entry. HMRC still requires a return for dormant companies unless they have formally confirmed in writing that no return is needed for that period.
