US tax guide for non-US owners of a US LLC

A practical guide to the key filing obligations for non-US residents who own a US LLC.

What you should know as an LLC owner

No federal tax on non-US income

If you live outside the US and do not have US-source income, you generally do not owe US federal income tax.

Annual filing is still mandatory

Even when no tax is due, you still need the required informational filing. Missing it can be very expensive.

US-source income can change the picture

If you have effectively connected US income, different tax rules can apply.

Wyoming has no state income tax

Wyoming does not impose state income tax on companies or individuals.

How the states differ

The state you form in changes your cost, privacy, and speed — but not your federal tax. Here is how the four states we support compare.

New MexicoLowest annual cost

$200

Annual state fee
No annual fee
Processing

The best all-round default — privacy, low fee, fast filing.

Delaware

$280

Annual state fee
$300
Processing
10–12 business days
Privacy
Medium — members are not public, but Delaware is the most scrutinized.
Best for
Startups raising from US VCs that expect a Delaware entity.

Florida

$300

Annual state fee
$139
Processing
10–12 business days
Privacy
Low — managers/members appear on the public annual report.
Best for
Owners who want a US/Florida footprint.

Every state also has a flat $100/yr registered-agent renewal from year 2.

Federal tax treatment is identical in every state: a foreign-owned single-member LLC files Form 5472 + a pro forma 1120, and only US-effectively-connected income is taxed. The state you pick does not change that.

All-in prices include our service, the registered agent (year 1), and the state filing fee. Annual state fees are paid to the state after year one.

Required forms:

What you sell changes your tax

Federal income tax is only part of the picture. If you sell physical products, US sales tax can apply — and it works very differently from income tax.

  • No US sales tax on most services sold to clients abroad.
  • Federal information return (Form 5472 + pro forma 1120) still required.
  • Tax only on US-effectively-connected income (usually none for remote work).

Sales tax

Most states do not tax professional or remote services, so sales tax rarely applies.

Form 5472 + 1120

The simplest case — typically no federal tax due, but the annual filing is mandatory.

The #1 misconception

Sales tax depends on where your customers are, not the state you form in. Forming in a “no-tax” state like Wyoming does NOT exempt you from collecting sales tax in states where you have nexus. Your federal filing (Form 5472 + pro forma 1120) is unchanged either way.

Important filing dates

1
January 1

Tax year starts

The US tax year usually runs from January 1 to December 31.

Six-month extension

Filing Form 7004 by the original due date extends the filing deadline to October 15.
