Hi. I have just started a limited company and it has started trading. I am keeping close eye on bookeeping and expenses etc, including a running total of corp tax liability. Turnover expected to be £3k for first year. I am also employed full time, earning £65,900 p/a and pay Class 2 NI. What NI, if any, do I need to pay for the limited company? There are no employees just me as director. Thanks.
