What is the best business structure for a U.S. expat running a consulting business abroad?

There is no single best business structure. The right choice depends on your income level, your country of residence (whether a totalization agreement applies), and how much of your time you spend serving U.S. versus foreign clients. Most expat consultants use one of three structures.

Quick comparison:

StructureBest forSE taxSetup burden
Sole proprietor / disregarded SMLLCIncome under ~$150k, single-country residency15.3% unless totalization appliesLow
Foreign corporationLong-term residents of no-totalization countries, income $150k+Avoidable via W-2 wagesHigh (Form 5471, GILTI)
S-corp (rare for expats)U.S.-facing consultants willing to maintain U.S. residency linkReduced via reasonable salary splitModerate

Key factors that should drive the decision:

  • Totalization agreement availability: if your country has one, a sole prop with a certificate of coverage solves most problems
  • Expected income: under $100k net, structured savings rarely justify the complexity
  • Client mix: U.S. clients paying in USD favor a U.S. entity; foreign clients paying in local currency favor a foreign structure
  • Long-term residency: planning to stay 5+ years in a country without a totalization agreement strengthens the case for a foreign corp
  • GILTI exposure: a foreign corp triggers GILTI, which can be painful without a Section 962 election

S corporations are mostly unavailable to expats because S-corp shareholders must be U.S. residents or citizens, and a nonresident alien spouse can disqualify the election.
