A Profit and Loss sheet would give a better illustration as to how the Company is performing, but as she is a Micro Entity, she isn't obliged to submit one to Companies House. However, as a Limited Company, she still has to take into consideration Corporation Tax and VAT payments (if she is VAT registered but that's usually for turnover over £85,000 so doubt she is registered as I am doubtful she earns anywhere near that). Corp tax is based on the previous years' profits. Standard rate is 19%. Also, if she draws dividend from the company then anything over 2k is taxed at 7% plus there's also NI contributions to take into account. Pensions also come out but you do get tax relief on these but that's if she pays into one. I know this as this is what I have to take into account for my Company but this may not be the case for Micro Entities as I am classed as a Small Company.
