First you have to send your money to your foreign account. If you have earned it as wages and it's in your ordinary bank account, you have already paid quite a lot of taxes. Your employer will probably not be comfortable sending your paycheck to the Virgin Islands. Maybe if you own a piece of a company, nobody knows about it and you sell it without your tax authority know it, you can get it deposited somewhere. But normally such sales require extensive documentation to IRS. So what you most likely evade is the capital gains tax on your stock investment profits done from the tax heaven. If you still want to live in the country you owe money, you can then get an ATM or Visa card that lets you access your foreign account and pay for the minor things, but you may not be able to buy a house and put it on your credit card. Many countries also have a limit on how much you can pay for with cash, and how much cash you can even transfer across borders without declaring it (10,000 EUR in EU). The Danish and Swedish tax authorities have been watching both activities in the last 10 years: if you somehow transferred a million dollars to the Cayman Islands, they might ask a few hard questions. If you were using a Visa card to pay for a hotel or restaurant, that came from a tax heaven, they might have found you too through another project that analyzed foreign Visa usage that wasn't consistent with tourists. No significant high profile arrests came of it though -- they mostly settled without significant penalty. The tax haven money transfer resulted in approx 150 million USD extra tax (which is a good for just 125 man-years spent). The credit card investigation gave approximately 70 million, but of that just 10% was actual penalties -- in most cases it seems like the money was treated as income adjustment. Sadly, the Danish tax authorities were then embarrassed by the biggest tax fraud ever, on a far larger scale then factory owners stashing money in Cayman Islands -- a massive 2 billion dollar fraud involving claiming back withheld dividend tax under double-taxation. They've only found 15% of the money so far...
