How to Choose a U.S. Company Type? LLC or Inc?
Why is Inc better than LLC for Chinese?
LLC is a pass-through entity, meaning profits are taxed on members’ personal returns. For Chinese owners without U.S. tax IDs (SSN or ITIN), filing is complicated and may cause double taxation (U.S. + China). In contrast, U.S. residents benefit from LLCs by paying tax only once at the personal level.
Inc (C-Corp) is a separate taxable entity.
C-Corp files its own taxes, so shareholders don’t report profits annually unless receiving dividends. Chinese non-resident shareholders (NRA) who don’t meet the substantial presence test aren’t required to file U.S. personal taxes if they don’t receive wages or dividends, making compliance simpler and clearer.
