If you don't have an accountant you are more likely to get checked you are in effect being left to your own devices to pay your Tax,the inland revenue also use computer programmes to show how your accounts alter from year to year month to month. They have far more weapons on there side than they ever did with technology these days,they are not daft they know on an average what you should be earning. It may be the genuine WCleaner that's people's enemy in there area if they are showing there easily doing 40-50k and you say your struggling to do 20-30 they may ask you for a chat. If your spending 60-Ł80 a week on fuel submitting the recipes and put down your earning 4-Ł500 don't be surprised if a recycled envelope drops on the doormat lol 😂
