For our small business owners or contractors working overseas, there is a consideration when it comes to tax deferred retirement planning. Currently the amount of foreign earned income that can be excluded from ordinary income tax is $104,100 for 2018. So, if you qualify as an expat and your income is less than $104,100, all your income is excluded.
Fast forward, if you elect to defer some of your earnings into a tax deferred retirement account you might be creating a tax liability unnecessarily. In other words, if your income was already being excluded from income tax, why put money into a tax deferred retirement account just to pay tax on the money later when that money was never supposed to be taxed in the first place. Huh? Stay with us.
You make $104,100. You pay $0 in taxes. You put $6,000 in a normal trading account. This $6,000 was never taxed and never will be. You make $10,000 on it because you’re smart. You sell the investments and recognized a $10,000 taxable gain all at capital gains rates.
Same situation, but with an IRA-
You make $104,100. You pay $0 in taxes. You put $6,000 (2019) in an IRA. This $6,000 is not taxed. You make $10,000 on it because you’re smart. You sell the investments, withdraw the money and recognized a $15,500 taxable gain, all at ordinary income tax rates.
There are more devils in the details of course, but you get the general idea. To put money away in a tax deferred retirement account when that income was already going to be excluded generally does not make sense. A Roth IRA in this situation would be more ideal.
Implementing a 401k plan sidesteps this problem. If you are a self-employed expat and you elect S corporation status, you can defer a portion of your salary and the business can make a profit sharing contribution (which reduces business income and subsequent taxes), yet you enjoy the full $104,100 exclusion on your W-2 and K-1 incomes. Save taxes with the exclusion, and defer taxes with the 401k plan. Not a true double-dip, but a good way to use two systems for tax savings simultaneously.
