Foreign-owned U.S. LLCs can face a $25,000 Form 5472 penalty. Learn why these penalties happen, relief options, and what to do after receiving a notice.

Whether a non-resident owes US tax on an LLC depends on where the income is earned, not on the owner's nationality or place of residence. A single-member LLC with no US trade or business and no effectively connected income generally owes no federal income tax, but it still has mandatory IRS filings, including Form 5472 with a pro-forma Form 1120. Multi-member LLCs, US employees, US inventory and state-level nexus change the answer completely.

Form 1120 is the annual US corporation income tax return that every domestic C Corporation must file with the IRS, including corporations that were dormant or lost money. LLCs that elected corporate taxation file it too, and foreign-owned US corporations usually attach Form 5472. The return is due on the 15th day of the fourth month after the tax year ends, with a six-month extension available on Form 7004.
