HMRC's "What is Active for Corporation Tax Purposes" at https://www.gov.uk/guidance/corporation-tax-trading-and-non-trading lists a number of activities that (in HMRC's eyes) constitute active status, including "receiving any other income".
Does the panel think a single bank transaction - the receipt of a loan from director of £10k - is likely to fall under "receiving other income" so that HMRC would no longer treat the company as dormant?
There were no other transactions whatsoever - no trading, no interest received, no assets; just a company bank account containing exactly £10k at the AP end. Incidentally, HMRC acknowledge (on the page linked above) that their definition of active differs from Cos House's definition and from FRS / IFRS definitions.
