How can I find out what tax code I'm on?

I heard there is a website that allows you to check your tax code, i cannot find it on google HELp?

• I think im paying too much tax, i heard there is a website that goes through all your circumstances and allows you to make sure you are on the correct Tax Code. Is this true and if so what is it?

• Answer:

  phone inland revenue - go on the website to find which number you need to ring, http://www.hmrc.gov.uk/ and then check with them about how much tax you should be paying. They were very useful when I was paying tax when I shouldn't have been and I eventually got a refund because they sent my employers the correct tax code, but I also had to make my employers ensure that I was put on the correct taxcode because they were really inefficient.
