I have a book keeper for VAT/sub contractors. Accountant for tax returns. I know a few lads who pay very little tax. I would rather sleep easy. Don't take the p**s with the tax man!. If you wish to live in this GREAT country and you don't mind working 7 full days a week to pay for lazy scum sucking leeches, ................ I can feel a rant developing
Keep all reciepts, mileage etc. Don't try to claim tax relief for daft things like a Mcdonalds meal etc.
Get a good accountant. One who you can trust with your life!
