With the Foreign Earned Income Exclusion (FEIE): Foreign Earned Income Exclusion one can exclude "the first $105,900 of foreign wages or self-employed income is excluded from U.S. federal income taxes as of the 2019 tax year."
I am a US citizen, and receive salary compensation from a local employer. I also pay into the MPF through my HK employer.
I claim as much as I can through the FEIE, but I am still slightly lower than the FEIE limit for my local wage income.
Is it possible to exclude only a portion of my wage income on the FEIE and pay some extra US taxes on some of my foreign wage income? And then used that US taxed earned income in order to contribute to a US retirement plan?
For example, say equivalent of $100K USD earned in Hong Kong through employer. I claim for FEIE exclusion $94,000 USD. But the $6,000 USD I don't claim.
Can I use that $6,000 foreign earned income (not excluded) for a ROTH IRA or Simple IRA contribution?
In other words, is the FEIE claim all-or-nothing, or can I partially claim a portion of my foreign earned income?
