The Malta Pension Plan is like a super charged cross border Roth IRA.
It offers a special tax favored retirement account created for high income tax payers. Ratified by the United States Senate, it offers unlimited contributions as compared to the low ceiling Roth pension plans allow.
Imagine an offshore pension fund in which the income you earn, including capital gains, cannot be taxed by the U.S. until you receive a distribution from that fund. And even then, portions of that distribution may be tax free.
