Doing your income tax returns online is fairly common these days. In the UK there are more than 3 million people that file their tax return online.
UK’s tax department, HM Revenue and Customs, is a little unclear on how secure this is. They’re providing an online service that be default should be secure.
But they’ve recently barred high profile people, including MPs, celebrities and the Royal Family, from using the same online system for security reasons.
If the system’s security isn’t good enough for high profile people then it shouldn’t be good enough for anybody. This can be taken as an admission that their security isn’t quite good enough to use.
