Answer

Classification comes first: whether the entity is a corporation, a partnership or disregarded for US purposes changes which forms apply and whether the profits are taxed currently. The filing set follows from the position, so the position is established first and the forms follow.

What actually has to be filed

Classification comes first: whether the entity is a corporation, a partnership or disregarded for US purposes changes which forms apply and whether the profits are taxed currently. An election made on time can align the two countries; the same election made late leaves credits stranded.

The exception worth knowing

The company you incorporated in the country you moved to is, to the IRS, a foreign corporation with a US shareholder — with a reporting package attached and rules that can tax its profits before you take them out.

What do I have to file as US person with a foreign business?
ItemAmount
Income taxed in both countriesC$75,000
Tax paid abroad (assumed 29%)C$21,750
Home tax on the same income (assumed 28%)C$21,000
Credit available (lesser of the two)C$21,000
Home tax still payableC$0

The credit fully absorbs the home liability on this income, so nothing further is payable at home — but the return still has to be filed and the credit still has to be claimed, by category and by country.

Illustrative figures, not a client engagement: the amounts are chosen to make the mechanism legible, and the rates and thresholds are assumptions stated for the example only. We confirm every one of them against the issuing authority for your own tax year before anything is filed.

Cross-border tax case studies

Case study 1

Classifying a company before the first US return was drafted

A client had incorporated a business in the country they had moved to and was about to file a US return treating the dividends as ordinary foreign income. We stopped at the classification question, examined the constitutional documents and the liability position of the owners, and established what the entity is for US purposes. The engagement produced a written classification conclusion with its reasoning, the reporting package that conclusion required, and a return built on that footing rather than on the assumption that the company was invisible until it paid something out.

Case study 2

A reporting package assembled from local statutory accounts

The company's books were kept to its own country's standards and in its own currency, and the US reporting wanted a different presentation. The work was reconciliation: restating the balance sheet and the result, identifying transactions between the owner and the company that the US side reports separately, and fixing the exchange rates used so the same basis could be repeated each year. The engagement produced the completed reporting for the open years and a working file the company's local accountant can populate annually without reinventing the method.

Case study 3

Profits taxed in the US before the owner had taken anything

An owner had left profits in the company deliberately, to fund growth, and was surprised to find the US treating part of them as theirs in the year earned. We established which categories of the company's income fell into that treatment and which did not, then examined how the eventual distribution would be taxed at home so the two events could be reconciled. The engagement produced the current year's position, a projection of the mismatch as the retained profits are drawn down, and the record needed to support the credit claims when they arise.

Case study 4

An election that would have worked had it been in time

A client had been told about the classification election years after starting the company, by which point returns had been filed on the default treatment and tax paid abroad on a different basis. We tested what the election would still achieve, which was less than the client had been led to expect, and identified which credits could no longer be matched to a year. The engagement produced that assessment, filings for the open years on a consistent basis, and a written note of the choice now foreclosed, so the history would be clear to any later adviser.

Case study 5

Co-owners abroad and one US shareholder among them

A business with several local partners had one US person in the ownership group, and the others had no interest in restructuring for a foreign tax system. We worked out what the US owner alone had to do, which information they were entitled to obtain from the company, and where their reporting could be satisfied without asking the other owners to change anything. The engagement produced the US owner's filings, a short annual information request the company could reasonably meet, and an explanation the other partners accepted.

Case study 6

Aligning a company's year end with a US filing

The company reported on its own country's fiscal year and the owner reported on a calendar year, so the profit figure in one system never matched the other. Rather than change the company's year, we built a conversion: a computation that restates the company's result to the period the US return covers, with the method documented. The engagement produced the restated figures for the open years, the reporting based on them, and a repeatable schedule, so the conversion is the same exercise every year rather than a fresh argument.

Case study 7

A US LLC Owned by a Canadian, Taxed Twice by Design

The two countries classify an LLC differently, so the credit relief that ought to apply frequently does not. The engagement looks at whether the structure can be changed, and where it cannot, at how to make the credit work.

Case study 8

A Canadian Working in the US on a Work Visa

Immigration status and tax residence are different tests, and a visa says nothing about which country taxes the salary. The file fixes residence, applies the employment article, and sequences the two returns so the credit lands where it is usable.

Core International & Cross-Border Tax Services

International Tax Planning & Advisory

Strategy and compliance for income, assets and families spread across borders.

One coordinating team: filings on every side of the border are sequenced so treaty relief and foreign tax credits are claimed once — and in the right country.

U.S. & Cross-Border Tax Returns

Dual filers: U.S. citizens in Canada and Canadians with U.S. income run two parallel systems — we prepare both, in the right order, every year.

Expat & Emigration Tax

The move year is its own project: the elections and valuations filed that year decide the next decade of both countries’ returns.

Non-Resident Canadian Tax

Default withholding is 25% of gross: elective returns routinely turn over-withheld rent and pensions into refunds.

Transfer Pricing & BEPS

Documentation prepared with the return is the cheapest insurance in international tax; reconstructing it during an audit is the most expensive.

Cross-Border Estates & Trusts

Wills drafted for one country routinely misfire in the other — deemed disposition here, estate tax there, credits in between.

Cross-Border Corporate Tax

Expansion raises the same four questions every time — entity, PE, repatriation, payroll. We answer them before the tax authorities do.

India Tax for NRIs & Returning Residents

The deduction is taken on the sale price, not the gain — which is why an NRI property sale strands cash unless the certificate is applied for before closing.

Canadian Tax with a Foreign Element

Residency is decided on facts, not on a form — and the year you arrive or leave is the one where the largest amounts turn on the smallest details.

UAE Tax for Expats & Their Home Country

A zero-tax country is only half the answer — the question that decides the bill is whether the country you came from still treats you as resident.

Global E-commerce & Marketplaces

Cross-border tax for sellers shipping worldwide: marketplace withholding, foreign registrations and inventory nexus handled before they become audits.

Marketplaces withhold, remit and report in their own right, so the tax position of a single sale is decided by where the stock sat, where the buyer was and which platform collected — not by where the company is registered. We reconcile the platform's own filings against the returns before either is submitted.

US person with a foreign business: further questions

Do I have to report a company I own abroad on my US return?

Almost certainly, and the reporting is usually more work than the tax. A company incorporated in the country you moved to is, from the US side, a foreign entity with a US owner, and ownership above a modest level brings an annual reporting package with it. That package is about the company, not merely about your dividends: its balance sheet, its result for the year, its transactions with you. The first question, though, is not which forms apply but what the entity is treated as for US purposes, because a corporation, a partnership and a disregarded entity each report differently.

Will the IRS tax my company's profits before I take them out?

It can. There are rules that attribute certain profits of a foreign company to its US owner in the year they arise, whether or not anything is distributed, and they were written with exactly this arrangement in mind. Which profits, and how much, depends on what the company does and how it is classified. The result owners find hardest is the timing mismatch: the US taxes the profit in one year and the other country taxes the distribution in a later one, so the tax credited in each country may not line up with the income it relates to unless the position has been planned.

Is my foreign company a corporation for US tax purposes?

That is the classification question, and it is decided by US rules rather than by what the company is called at home. The default treatment depends on the entity's characteristics, chiefly whether the owners have limited liability, and it can differ from the treatment the same entity gets in its own country. Classification is not a detail to settle once the returns are drafted. It determines which reporting package applies, whether the profits are taxed to you as they arise, and whether the tax the company pays abroad can be credited against your US tax at all.

Can I choose how my foreign company is treated in the US?

In many cases yes: an election can change the classification from its default, and that is the main lever available for aligning the two countries' treatment of the same business. Made on time, it can put the profit and the tax in the same place in the same year, which is what makes the credits work. The election is a decision about the future as much as the present, because the treatment you settle on has to suit how you intend to take money out of the business, not only how the current year happens to look.

What happens if I make the classification election late?

The same election that solves the problem on time can create one when it is late. The risk is stranded credits: the US taxes income in a year on one basis while the other country taxed it on another, and a credit that cannot be matched to the right year and the right category of income is often simply lost. A late election may also carry conditions about the years in between. This is why classification is looked at when a business is set up or acquired, rather than when a first US return is being prepared two seasons later.

Does the corporate tax my company pays abroad reduce my US tax?

Sometimes, and the mechanism is narrower than owners expect. Credit is given for foreign tax, but it has to be matched: the right taxpayer, the right year, the right category of income. Tax paid by a company is not automatically tax paid by you, which is why classification matters so much. It decides whether the company's tax is yours for credit purposes or belongs to a separate person the US recognises. Where the match fails, the same profit can be taxed in both countries with no relief, not because the treaty is absent but because the claim cannot be constructed.

What happens if I have not filed for several years?

Missed years are handled as one package, not one at a time, because the route chosen for the first year determines the relief available for the rest. Each country has a disclosure or relief programme with its own conditions, and entering the right one — before the authority contacts you — is usually what keeps penalties down. Filing quietly outside a programme forfeits that protection. See catching up on missed returns.

Is "fund transfer pricing" the same thing as transfer pricing?

No — and if you came here to calculate FTP, this is not it. Fund transfer pricing is a bank's internal allocation of funding costs and benefits between its own business units, a treasury and asset-liability management discipline used to measure branch or product profitability. Tax transfer pricing is about prices between legally separate related parties across borders, and about which country taxes the resulting profit. The words overlap; the fields do not.
