The mistake I see all the time: US expats making tax elections to save money in one year without understanding the long-term consequences.
A couple lived in Dubai. Zero tax. The US spouse's advisor said "pull your non-US spouse into the tax return and save a few thousand dollars."
It worked. They saved money that year.
Then they moved to Germany. The non-US spouse started earning significant income from a separate venture.
Now both spouses are entangled in the US tax system. And they have no idea what actually happened.
The pattern:
We make elections to save a couple hundred or a couple thousand dollars in one year. Then we have to unwind those elections later because they don't make sense long-term.
And unwinding is expensive.
The lesson:
Tax planning for US expats can't be based on one year's savings. You need to think about what happens when you move, when income changes, when life circumstances shift.
Joint filing elections. Foreign tax credit vs exclusion decisions. Roth conversions. All of these need long-term strategy, not just immediate tax savings.

Who this applies to:

US expats in low-tax or zero-tax countries making filing status decisions
Mixed-citizenship couples where one spouse handles "the US side"
Americans moving between countries with different tax treaties
Anyone who's filed jointly without understanding the consequences
