Sometimes they need only the smallest amount of information to act upon - as little as a mobile number, even with no name and address.<\/span><\/p>\n<p style=\"padding-left: 0px;\"><span style=\"font-weight: 400;\">If you are an expat <strong>living in Spain with outstanding UK tax issues<\/strong>, then do not assume that HMRC don\u2019t have the means to find out information about you, your business and your assets.<\/span><\/p>\n<h3 style=\"text-align: center;\"><span style=\"color: #ff7231;\"><u> How does HMRC do this?<\/u><\/span><\/h3>\n<p style=\"padding-left: 0px;\"><span style=\"font-weight: 400;\"> They use their software called CONNECT.

And it is still being expanded to achieve more and more. <\/span><\/p>\n<p style=\"padding-left: 0px;\"><span style=\"font-weight: 400;\"> It can take months of work for HMRC to build a case, especially if the starting point is a mobile phone number. However, a breakthrough in progress can come at any time. By using other complementary investigative software, previously unseen links can be established.
