I've investigated the error for MINI CONCEPTS LIMITED.
The issue is with the dates you've entered on the form. The "prior period end date" (30/04/2025) is the same as your current period end date (30/04/2025). These dates must be different - the prior period end should be the end of your previous accounting period.
For a company with year end 30 April 2025, if this is your second year, the prior period end would typically be 30 April 2024.
Please go back to the form, correct the prior period end date, and click "Preview & Submit" to regenerate your documents.

Thanks Tim,
Sorry, you mean the form I filled during step 1? But I didn't see any field for "prior period end date"? I'm submitting CT600 only if that's the reason.
Would you be able to give me a quick call please?
Many thanks,
Karina
