You can voluntarily register for vat no matter what your earnings are
Ok.
I can't see how this could possibly benefit a new start sole trading windy though? It would be hard enough without carrying a 20% handicap to the competition! I don't think VAT reclaimed on start up costs would outweigh this & throw in the extra paper work & the vat man.
Possibly, but being VAT registered would have also encouraged me to go for more commercial work as they can reclaim it. I believe that many customers would be OK with paying this from the start. It might be more of a problem if 20% was lumped on later though. It's possible that I'm referring to the sort of customer who wants the security of knowing that the guy who cleans their house as an officially registered business and deduces from that that they are more likely to be trustworthy and not a fly-by-night.
Of course you may be right. I'm not trying to present this as absolute fact but just putting it out there.
If computerisaTION HAD BEEN THE NORM WHEN i STARTED, I may well have gone for VAT. Without affordable computerisation (it was 1991), it wasn't practical though. Apart from that, it took a while for me to decide to stick with window cleaning.
