I pay £24 p/w £1248 p/a. Are you an accountant by any chance?
CT is 20 % of your yearly profit, as a contractor i had no real outgoings only salary/dividends so my profit was of course high hence the high CT. Now i don't claim to know a lot about it all worked, that was what my accountant (Tax Assist) told me. I got lost in it all and found it complicated so went down the Umbrella path.
Yes around £1200 plus VAT is about right for the Brighton area - In answer to your other question YES I'm Tax Accountant/ Tax Lawyer/ Ex HMRC ''Black Economy'' Tax Inspector
