I’m an accountant and I can make some guesses on her income based on the accounts registered at Companies House and give some insight into the lodged figures.
The £9k salary stated is the most tax efficient salary any accountant would recommend a client take. This means that she had a full year of NI credit towards her state pension. The rest of her income is likely to made up of dividends - there are none declared as technically the company is insolvent, but as the tax year runs to April and her accounting year is to October, they’ve likely voted nothing to 31 October due to the negative equity and are waiting until the next the next accounting year after 31 October when it is likely they are back in the black so to speak. The other taxes and social security figure is likely to be just Corporation Tax due at 19% - you can work back the figure if you want to take a guess at her taxable profit - there may have been deductions that we cannot see however. My next guess would be the other creditors figure is mostly her director’s loan figure, ie money she’s taken from the company but has not been covered by salary or dividends voted (yet) and potentially a company credit card balance. You can add that figure to the salary stated if you want to guess at her income. Keep in mind dividends are taxed at 7.5% in the basic rate band and not the 20% us idiot PAYE workers are charged.
As a reminder, I am not her accountant and I’m just making educated guesses on what I can see from publicly available information. Reporting a £9k PAYE salary and then taking the rest of their income in dividends at the lower tax rate is 100% legal and a lot of people do it - whether it is moral is another discussion!
