I didn't pay very much tax at all myself. I switched to WFP and in my first year I turned over no more than my last year with trad. I could have but there were issues in my personal life that took up lots of time. Set against that were my largish outlays for WFP gear and the first year of capital allowances. In fact, my bill was quite low without even factoring in the van. My accountant said that if I factored in the van, my bill would be below zero. As this would be wasteful, he has delayed factoring in the van until the following year (perfectly legal apparently). I wasn't aware of this but you can delay bringing a capital item into the accounts for as long as you wish if there is an advantage to be gained from doing so. Next bill will be larger though even with the van's first year allowance.
