Digital vat return just means doing it online rather than on paper and posting it. I'd be surprised if anybody doing it the old fashioned way in this day and age so to the o.p you are probably already doing it digitally. As for completing it all you need is a simple bit off sw that can add up.the vat on expenses , which in.our industry is not that much as our vat inclusive purchases are minimal. Few poles, valves, bit of office equipment and diesel. Easy to do.
