Answer

US corporations with income from selling goods, services or intangibles to foreign customers. The obligation is decided by facts rather than by tax owing, which is why a nil position does not remove it.

The rule on who files

US corporations with income from selling goods, services or intangibles to foreign customers.

The exception that catches people

The deduction rewards export income earned inside a US company, which makes it the mirror image of the low-taxed foreign income rules — and the reason structure choice for a services exporter is a computation, not a preference.

Who files Form 8993?
ItemAmount
Income taxed in both countriesC$137,000
Tax paid abroad (assumed 22%)C$30,140
Home tax on the same income (assumed 40%)C$54,800
Credit available (lesser of the two)C$30,140
Home tax still payableC$24,660

The credit absorbs C$30,140 and leaves C$24,660 payable at home, because the home rate on this income is the higher of the two. The balance is real cash and it is due on the home timetable, which is why instalments get raised in the first meeting.

Who has to file US tax return — what this page covers

Most readers of this page are looking for who has to file US tax return. What follows sets out how it works for Form 8993: who is caught by it, what has to be filed, and what the work costs, agreed before it begins.

Cross-border situations we are engaged for

Case study 1

Splitting a services ledger between domestic and foreign customers

A software consultancy billed clients in several countries from one ledger that recorded little more than a name and an amount. The deduction depends on that split, so the engagement began with the sales records rather than with the tax computation. We read the contracts to establish where each customer sat and where the service was used, reclassified the revenue on that basis, and identified the accounts where the evidence was too thin to support a claim. The output was a revenue analysis by customer location, a claim computed on the supportable part, and a billing checklist for the following year.

Case study 2

Deciding entity classification for an exporter before the year began

A practice serving clients abroad was taxed directly to its owners and therefore outside the deduction this form claims. We modelled the same revenue and profit on both footings, including what changing classification would mean beyond this one deduction, and stated what each produced. The fee was agreed in writing before the work started. The engagement produced a written comparison of the two bases on the client's own figures, a note of the non-tax consequences, and a record of the decision taken, which was to change with effect from the start of the following year.

Case study 3

Documenting where a licensed intangible was actually used

The client licensed software to distributors who sublicensed it onward, so the question was not where the invoice went but where the product was used. We worked through the licence chain and the distributors' own reporting to establish the territories of use, and separated the royalty stream accordingly. Some of it could be supported and some could not. The engagement produced a territory analysis for the royalty income, a claim limited to the part the evidence carried, and changes to the licence reporting schedules so later years arrive with the information already in them.

Case study 4

Choosing between a US company and a foreign one on the numbers

A founder serving overseas customers wanted to know whether to keep the business in a US corporation or move it abroad. We treated it as a computation rather than a preference: the same projected revenue run through both positions, one drawing on the deduction for foreign-derived income and the other sitting under the rules that tax a foreign company's profits to its owner as they arise. The engagement produced side-by-side computations, a written statement of the assumptions behind each, and a recommendation the client can revisit as the customer mix changes.

Case study 5

Testing a claim against a multinational customer's own structure

The client's largest customer was a group with entities in several countries, and the contract named the parent. Which part of the group received the service decided how much of the revenue supported a claim. We read the statements of work against the group's structure, identified where the people who used the service sat, and apportioned the revenue on a stated basis. The engagement produced an apportionment supported by the contract documents, a computation built on it, and a contracting note asking for the receiving entity to be named in future work orders.

Case study 6

Reviewing a claim prepared without supporting records

A claim had already been made, on revenue the accounts described simply as export sales. We tested it the way a reviewer would, picking customers and following the contract, the delivery terms and the payment, then asking what actually showed where the goods had gone. Part of the claim stood and part had nothing behind it. The engagement produced a reviewed schedule separating the two, a reduced claim the file can carry, and a list of the records the business needs to keep so that the next claim does not need this exercise.

A US Citizen Settled in India, Filing on Both Sides

Residence in India and citizenship in the United States produce two annual returns for one income. The order decides the credit, and the Indian financial year and the US calendar year have to be reconciled before either is prepared.

Whether the Year Made Someone an NRI

Indian residence is decided by presence tests applied to the financial year, and a single trip can change the answer for the whole of it. The status is established before any return or exemption is considered.

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.

Performance income is taxed where earned — Regulation 105 in Canada, withholding agreements in the U.S. — with special treaty articles overriding the usual rules.

Performance income is taxed where the performance happens, and the deduction is usually taken at source on the gross fee before expenses. Recovering the difference is a filing exercise in the other country, and it only works if the tour, the residency and the withholding certificates were documented while the work was being done.

Form 8993 — the questions that follow

Can my US company claim the export deduction on Form 8993?

If it is a US corporation with income from selling goods, services or intangibles to foreign customers, this is the right form to look at. The deduction is for foreign-derived intangible income earned by a US company from serving foreign markets, so two things have to be true: the entity has to be of the kind the deduction is written for, and the income has to come from customers or uses outside the country. Domestic sales do not qualify however profitable they are. Start by separating the revenue according to where the customer sits and what was delivered, because that split is the computation.

Do sole proprietors and partnerships file Form 8993?

The deduction is written for US corporations, so a business whose profits are taxed directly to its owners does not reach it in that form. That makes entity classification a live question for an exporter rather than a formality: the same consulting practice, serving the same foreign clients, can be inside or outside this deduction depending on what it is treated as for tax purposes. Changing classification has other consequences and is not a decision to take on this point alone. It is worth modelling before the next year begins, because the answer is a computation on your own numbers rather than a general rule.

Does selling services to foreign clients qualify for Form 8993?

It can. The deduction is not limited to physical exports: income from providing services to foreign customers, and from licensing intangibles used abroad, is within what it is aimed at. What matters is where the customer or the use sits, not where the invoice was raised or the work performed. For a services business that usually means the evidence problem comes first, because you have to be able to show, client by client, that the recipient was outside the country and that the service was provided for use there. Build that into the billing records rather than reconstructing it at the year end.

Do I need a foreign office to claim this deduction?

No, and that is rather the point of it. The deduction rewards export income earned inside a US company, which makes it the mirror image of the rules that tax profits earned in a foreign company. You do not have to put anything abroad to claim it. You have to sell abroad and be able to demonstrate it. This is why structure choice for an exporter is a computation rather than a preference: earning the same profit inside a US corporation and inside a foreign one produce different results, and which is better depends on your own numbers rather than on instinct.

How do I prove my customer was outside the United States?

Documentation, and the standard is higher than an address on an invoice. The practical requirement is a record supporting where the customer was and where what you sold was used or consumed: contracts, the terms of delivery, shipping records for goods, and for services some evidence of where the recipient took the benefit. Where the customer is itself a multinational, the harder question is which part of it received the service. Decide what you will keep before the year starts and collect it as you bill. Assembling it afterwards from a sales ledger that records only a name and an amount is the common failure.

Should I move my business abroad or claim this deduction instead?

Neither should be decided as a preference. Earning export profits inside a US corporation brings this deduction into play. Earning them in a foreign company brings a different set of rules, under which active profits can be taxed to the owner as they arise whether or not anything is distributed. Those are two sides of the same policy, and the better answer is whichever the computation gives on your facts, taking account of margin, where the customers are, and what the foreign jurisdiction charges. We model both on the same revenue before advising, and put the comparison in writing so the decision can be revisited later.

Are foreign trusts taxable in Canada?

They can be. Canada's deemed-resident-trust rules can pull a non-resident trust into the Canadian tax system where there is a resident contributor or, in some cases, a resident beneficiary — taxing it as though it were resident here. Separate reporting applies to transfers or loans to a non-resident trust and to distributions and debts from one. The planning point is that contributing to an offshore trust from Canada rarely achieves what the brochure suggests. See non-resident trusts.

Branch or subsidiary — which should we use to expand?

A branch keeps one taxpayer: results consolidate at home, losses are usable sooner, and the exposure is that the branch is a permanent establishment whose profit the host country taxes, sometimes with a branch tax on repatriation. A subsidiary is a separate taxpayer with limited liability and local rates, at the cost of withholding on dividends home and transfer pricing on everything between them. The deciding facts are usually expected losses, liability and exit plans. See branch against subsidiary.
