Suretrader is now making all US traders fill out a Foreign Account Tax Compliance Act (FATCA) and W-9 (email went out ao all traders today). When you complete this the US Agencies will know you have/had a foreign account. If you did not also complete an FBAR form with your income taxes for the year you had an account at Suretrader I feel bad for you...the penalty is ridiculous. Please consult your own accountant and attorney....don't take legal and tax advice from the internet.
