IRS remains committed to its priority efforts to stop offshore tax evasion wherever it occurs.  It pursues cases in all jurisdictions of the world.  Over the years, numerous individuals have been identified as evading US taxes by hiding income in offshore banks, brokerage accounts or nominee entities; using debit cards, credit cards or wire transfers to access the funds. Others have employed foreign trusts, employee-leasing schemes, private annuities or insurance plans for the same purpose.
