What you owe HMRC is more than what is in the account. There is £41,200 in the bank and £58,200 of tax against it, so you are £17,000 short before anything else is paid. The VAT return of £26,800 went past its due date 4 days ago.
I want to be direct about what this is. This is not a cash flow question that gets solved by collecting faster, because even collecting everything owed does not close the gap in the time available. This is a payment plan question.
HMRC's Time to Pay line takes calls about exactly this, and the businesses that get workable terms are the ones that call before enforcement starts rather than after. Four days late is early. Four months late is not, and the difference in how the conversation goes is large.
The corporation tax bill of £18,500 is due in 38 days, so any arrangement should cover both rather than solving the VAT and meeting the same problem again next month.
I would make that call this week. Everything else on this page can wait until it is made.
