In short

Project-based engineering work is caught by the construction and service permanent-establishment provisions, which count project duration rather than individual presence.

On this page: the rule that applies here, the questions we are asked first, two finished files with their numbers, how an engagement runs, and the fee it starts from.

The rule that applies to this group and not the one next to it

Project-based engineering work is caught by the construction and service permanent-establishment provisions, which count project duration rather than individual presence.

Everything else on this page follows from this. Two people with identical incomes and identical passports can owe completely different amounts because one of them falls inside a provision the other does not. That is the whole reason this page exists as its own page rather than as a paragraph on a general one.

The team reviewing a file together at a desk

Engineering firms cross border tax — priced before we start

An engineering firm's fee is set by the projects, not the headcount. Each overseas project has to be tested against the duration thresholds in its own treaty, so one long-running site is a contained assessment and a portfolio of concurrent projects in several countries is a substantially larger one. Fixed in writing before work starts.

Three things we hear on the first call

  • Our projects abroad run longer than the treaty thresholds.
  • Clients withhold on our fees at gross, including reimbursables.
  • We staff projects with people from several offices and payroll in one.

These are not edge cases. They are what happens when two systems each apply their own logic to one person, and the person is expected to reconcile the result. See also simplified vs normal GST/HST registration.

The arithmetic, worked through

Numbers make this concrete, so here is the same rule applied to a set of figures.

Splitting one salary between two countries

A salary of C$176,000 for a year with 230 working days, 132 of them performed in the other country. Employment income is generally sourced to where the work was physically done.

ItemAmount
Annual salaryC$176,000
Working days in the year230
Days worked in the other country132
Days worked at home98
Income sourced to the other countryC$101,009
Income sourced at homeC$74,991

C$101,009 is sourced abroad on this split, which is the figure the host country taxes and the figure the home credit is computed on. Reproduce this from a travel record, not from memory — it is the first thing an auditor asks for. The interesting question is where your own figures fall relative to that, which is a computation rather than an opinion.

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.

Worked through with figures

Here is the rule doing its work on an actual set of amounts.

Credit relief on one stream of income

Take C$101,000 of income taxed in both countries. Assume the other country charged 23% on it and the home country would charge 40% on the same amount.

ItemAmount
Income taxed in both countriesC$101,000
Tax paid abroad (assumed 23%)C$23,230
Home tax on the same income (assumed 40%)C$40,400
Credit available (lesser of the two)C$23,230
Home tax still payableC$17,170

The credit absorbs C$23,230 and leaves C$17,170 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. We run this on your actual numbers before advising anything, because the conclusion can invert with a modest change in inputs.

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.

How we handle it

  1. 1We establish what happened and when, because every position here is anchored to a date
  2. 2A written scope and a fixed price, so you know the cost before committing
  3. 3The filings are prepared, cross-checked against each other, and reviewed by name
  4. 4You see the result, approve it, and we file it
  • A named reviewer signs off every statutory filing.
  • A change of scope is re-quoted before the work, never added to the invoice after it.
  • Consultations scheduled to your working day rather than ours.

Your next step

Send us the facts and we will tell you what has to be filed and what it costs.

Fixed fees around engineering firms cross border tax

This second band covers the recovery work. Where clients have withheld on engineering fees at gross, including reimbursable costs, each contract and each certificate has to be traced back through the treaty before relief can be claimed, so what drives it is the number of withholding clients and of staff payrolled out of one office onto another country's project.

The difference a dedicated cross-border team makes

Both sides prepared together

Two returns built against each other by one team, so relief is claimed exactly once and nothing falls between the two systems.

Filed with the authority, not just prepared

The engagement runs to submission and to the correspondence that follows it, including the queries that arrive months later.

The reporting penalties get named early

The heaviest exposure on a cross-border file is usually a disclosure form, not the tax. We identify which ones apply before a deadline turns into a penalty.

One team, not two firms billing separately

You are not the go-between for two sets of advisers with two sets of assumptions. One engagement covers each country the file touches.

Cross-border tax case studies

Case study 1

Withheld at the Statutory Rate When a Treaty Rate Applied

Where withholding has already gone out at the full domestic rate, the treaty rate is recovered rather than applied. The file establishes entitlement for each payment, then puts the documentation in place so the following year runs at the correct rate from the start.

Read how this one runs
Case study 2

Treaty Rate Refused Because the Paperwork Was Missing

A reduced rate under a treaty is available only where the payer is satisfied the recipient is resident in the treaty country. The certificate and the withholding form are what make the rate available at source instead of recoverable a year later.

Read how this one runs
Case study 3

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.

Read how this one runs
Case study 4

Paying a Dividend Up to a Foreign Parent

The withholding rate depends on the treaty, on the size of the holding, and on whether the parent is the beneficial owner rather than a conduit. Establishing all three before the payment is what secures the lower rate at source.

Read how this one runs
Case study 5

A Margin Defended With a Benchmarking Set That Fits the Facts

A comparables set is only as good as the screening behind it, and a rejected set takes the margin with it. The study selects the tested party first, screens on function rather than on industry code, and records why each comparable survived.

Read how this one runs
Case study 6

A Company Abroad Owned by a US Person

A business incorporated where the owner lives is a foreign corporation to the IRS, with a reporting package of its own and schedules that need local accounts restated. Classification comes first, because it decides what is reportable and when profits are taxed.

Read how this one runs
Case study 7

An IRS Notice for a Year the Client Believed Was Settled

Most notices are proposals rather than assessments, and they carry a response window that is shorter than it looks. The engagement reads what is actually being proposed, gathers the support, and replies inside the window with the position rather than a request for time.

Read how this one runs
Case study 8

Withholding Reduced by the Right Article

Dividends, interest and royalties each have their own article and their own rate, and the payer applies whichever it is satisfied of. Establishing entitlement before payment is what secures the lower rate at source.

All case studies — every published engagement in one place.

Cross-Border Real Estate

Foreign property income and sales are taxed in both countries by default; Section 216, FIRPTA and treaty credits are the standing toolkit.

Property is taxed where it sits, which is the one rule no treaty overrides. What the treaty does decide is the credit, the rate on the rent and what happens on the sale — and the clearance certificate on a disposition is applied for before closing, not after the buyer has already held the money back.

Engineering firms cross-border tax — questions we are asked

What makes engineering firms different from an ordinary filing?

Project-based engineering work is caught by the construction and service permanent-establishment provisions, which count project duration rather than individual presence. An ordinary preparer applies the general rule and stops there, which is how the relief in the specific provision goes unclaimed.

Can you work with my existing accountant?

That is how most of these engagements run. They keep the domestic file, we take the cross-border piece, and the boundary is agreed in writing so nothing is done twice or missed.

What happens if the two countries disagree about which of them can tax me?

The treaty has a procedure for exactly that. You apply to the competent authority in your residence country, which takes the case up with its counterpart, and the two negotiate a position that removes the double taxation. Some treaties add binding arbitration if they cannot agree. It is slow and it runs on documents, so the practical work is preserving the record and filing protective claims while the clock runs. See our treaty work.

Which countries have a tax treaty with the United States?

Around sixty, including Canada, the United Kingdom, India, Australia and most of western Europe — but the list matters less than the terms, because each treaty caps rates and allocates income differently. Two countries with treaties can produce opposite answers on the same pension or the same royalty. What decides your position is the specific article covering your income type. See our country guides.

How is the fee set?

It is agreed in writing before any work begins, based on the scope we establish on the first call. If the scope changes we re-quote before continuing — there is no hourly meter running in the background.

Do you use software I need to learn?

No. You send documents through the portal and receive the finished filings back; everything else happens on our side.
