    Corporation Tax can be a very complicated payment to set up and pay. The article gave me the correct advice, that it is better to have a professional Chartered Accountant to prepare and submit the return. Anyone who may wish to try and attempt the return themselves, would find it a very complex area of a business to deal with and if you don’t know what you are doing you could easily find yourself paying penalties and maybe even be investigated by HMRC.
    On reading the article though, Legend Financial definitely have the knowledge, experience and the right advice to help me in this area of business that is very difficult.
