Do I file Form 8858 even if no tax is owed?
Information return obligations of this kind are generally required on the facts rather than on the tax result, so a nil position does not remove one. US persons who own a foreign entity that is disregarded for US purposes, or who operate a foreign branch of a US business.
What happens if I have missed Form 8858 for several years?
Missed years are dealt with as a package rather than one at a time, because the route chosen for the first year affects the relief available for the rest. We map the years and the obligations before anything is filed.
Is Form 8858 the same as the other reports I already file?
No. Reports a foreign disregarded entity or a foreign branch owned by a US person — its income, expenses and the currency it operates in. Satisfying a different obligation, even one covering the same accounts or entity, does nothing for this one.
Do I file Form 8858 for a single owner company abroad?
If the foreign entity is disregarded for US purposes and you are the US person who owns it, the reporting runs with it. Disregarded means its results are not taxed separately from yours; it does not mean unreported. Income, expenses and the currency the business operates in are all reported, and the entity's results are folded into your own return. Owners often assume that because the foreign company files its own accounts and pays its own local tax, the US side is covered. It is not. The local accounts are the starting material for the US filing, not a substitute for it.
What counts as a foreign branch for this form?
A branch is the business you carry on abroad without a separate foreign company sitting over it — an office, a site, a place of business operating as part of your existing trade. The point people miss is that nothing has to be incorporated for the reporting to arise. If the operation abroad has its own activity, its own costs and its own working currency, it has the characteristics the form asks about. Where the line falls in a particular case depends on how the operation is actually run rather than on what the arrangement happens to be called locally.
My accountant abroad keeps the books in local currency — is that enough?
It is the starting point, not the finished article. The reporting asks for results in a way the foreign bookkeeping was never prepared to produce: the functional currency has to be identified, and a translation method applied consistently, before the figures mean anything on a US return. A set of accounts prepared to local standards will have classifications, depreciation and timing that do not map across on their own. In practice the work is a reconciliation — local accounts in, US-basis figures out, with a note of every adjustment so the same treatment can be repeated the following year.
Do I still file if the foreign business made a loss?
Yes. The reporting is not conditional on profit, on tax being due anywhere, or on money having been sent home. A loss-making branch or disregarded entity reports its income and its expenses in the same way a profitable one does. It matters for a second reason as well: losses only do anything useful for you if the results have been computed on a US basis in the first place, and that computation is the same work the filing requires. Skipping a lean year leaves a gap in the record that is awkward to explain when the operation turns round.
Is Form 8858 the same as reporting a foreign corporation?
No, and the distinction is what the entity is treated as rather than where it sits. This filing deals with an operation whose results are folded into the owner's own return: a foreign disregarded entity, or a branch. An entity treated as a corporation for US purposes is a separate matter with reporting of its own. The classification question therefore comes first, because the same foreign company can fall on either side of that line depending on how it is treated. Getting the answer in writing at the outset saves preparing the wrong return for several years and then unwinding it.
What happens if I have never filed Form 8858 before?
It is a common position, particularly where a foreign operation grew out of freelance work and was never formally set up as anything. The repair is to establish the classification, rebuild the results for each year on a US basis, and file for the years concerned as a set rather than one at a time, so the figures carry forward consistently. Penalties attach to unfiled information returns and are assessed by form and by year, which is why exposure grows quietly with time rather than all at once. Correcting it before the tax authority raises it is materially better than after.
What is a permanent establishment, and how easily do we create one?
A taxable presence in another country under the treaty — typically a fixed place of business such as an office, branch, factory or workshop, or a dependent agent habitually concluding contracts on your behalf. Some treaties add a services test measured in days. Purely preparatory or auxiliary activity is excluded, but that carve-out is narrower than it sounds: one senior employee working from home in the other country, with authority, has been enough. See business profits and permanent establishment.
Which business structure has double taxation?
The corporation — specifically a US C corporation, where profit is taxed to the company and the dividend again to the shareholder. Sole proprietorships, partnerships and LLCs treated as flow-throughs are taxed once, in the owners' hands. Across borders that tidy answer breaks: an entity treated as a flow-through in one country can be opaque in the other, which produces a mismatch neither system planned for. See LLC against corporation for Canadians.
