my CT600 appears overdue

my CT600 for year ending 31 Oct 2024 was submitted in February 2025 but your system shows it overdue by 3 months

TinyTax syncs filing deadlines from Companies House, but Companies House only tracks Accounts filings - they don't have visibility of CT600 submissions (those go directly to HMRC). So we can't automatically know when a CT600 has been filed elsewhere.

To clear the overdue warning, you just need to mark it as filed:

1. Go to your TinyTax dashboard

2. Find the row for YARN BY THE WATER LTD with period ending 31 October 2024

3. Click the dropdown button (e.g., "Start Filing" or "Actions")

4. Select CT600 Filed Elsewhere

This will update your dashboard to show the CT600 as complete.
