Question 1: No you don't really need to but £700 for accounts, corporation tax submission, personal tax return and payroll is a reasonable fee. Question 2: The amounts in creditors are most lostkely to be corporation tax and the accountant's bill Question 3: Correct - bank balance doesn't affect tax Question 4: It's not clear whether this is a rent charge or a use of home as office expense claimed. Rent would usually entail a lease between you and the company, but has several other points of consideration e.g. personal tax, PPR etc. Rent is also usually contactual meaning you can't pick and choose whether to include it. There is much more flexibility with the use of home as office charge but really anything above £4/week is open to challenge from HMRC Question 5: The business profits can't repay a DLA only you, as the director can do this.
