Since then, the HMRC website and its content have been being migrated to new government online portal, GOV.UK.
Webpages, guidance and manuals have made the move, and accountants have been concerned about the quality.
"They do seem to be so simplistic that they are positively misleading." said Paul Wakefield.
One practitioner who found the new site not all that bad, is Paul Scholes.
"It did come as a bit of a shock a couple of weeks back when I returned to a bit of EU VAT stuff I'd been looking at the day before and got transported to the new site, however now that I've spent some time digging and surfing I don't think it's that bad.
"The detailed stuff is still there and it's certainly easier for Joe Public to use the basic guidance and, don't forget, that's who it's designed for (we're supposed to know it all!)," he said.
In a blog earlier in June, HMRC's Agent Strategy, stakeholder and engagement team encouraged accountants to give feedback. It also asked them to report any errors or omissions they found on the site.
But member Ken Howard, who said he has reported errors multiple times, has claimed his reports are going unnoticed.
Another element of the site accountants are concerned about is the ability to find the relevant information. Several members have said they had 'given up' searching for material after being redirected around the website.
