The short answer

The multilateral instrument rewrote parts of hundreds of existing treaties at once, which means the treaty text you downloaded is not necessarily the treaty in force. Its principal-purpose test denies a benefit where obtaining it was a principal purpose of an arrangement, unless granting it accords with the treaty's object.

Whether this is your situation

  • A treaty position needs to be claimed or disclosed on a return
  • The treaty text you are relying on may have been modified
  • An entity in the chain has never been tested against the eligibility rules
  • A withholding certificate on file has expired
  • One country has adjusted a position and the other has not followed

That list is deliberately concrete. If you recognise yourself in it, this page is the right starting point; if you do not, tell us and we will point you elsewhere without charging for it.

Transparent, fixed pricing for MLI principal purpose test

What sets the fee on principal-purpose-test work is how many treaties in the structure have to be read as modified by the MLI, with the reservations and notifications each country made checked in turn, and how many arrangements need a commercial-purpose record built.

Dual filing — 1040 + T1 together — fixed-fee price

From $449

fixed, quoted before work starts

Both returns prepared as one engagement, in the order the credit requires, so relief lands where it is usable rather than being claimed twice in the wrong place.

How the rule actually works

The multilateral instrument rewrote parts of hundreds of existing treaties at once, which means the treaty text you downloaded is not necessarily the treaty in force.

Its principal-purpose test denies a benefit where obtaining it was a principal purpose of an arrangement, unless granting it accords with the treaty's object. Checking the modified text, and the reservations each country made, is now part of every treaty position.

The practical reading of that is simple enough. Establish the position first, in writing; assemble the evidence that supports it; then prepare the filings in the order that lets the relief actually land. Doing those three in the other order is how the cost of MLI & the principal-purpose test multiplies.

Thresholds and rates move, and summaries written for last year are not evidence about this one. So each figure in your file is sourced to the issuing authority for the specific year; anything we cannot source, we describe as a mechanism and leave unquantified until it can be confirmed. See also dual citizen with two passports, two returns and Canada–Saudi Arabia tax corridor.

What we actually file

  • Correspondence with payers who applied the wrong rate
  • Confirmation of the treaty text actually in force for your year
  • Treaty-position disclosures on the return
  • Residency certificate applications and eligibility declarations
  • Waiver and reduced-withholding applications before payment

The arithmetic, worked through

It is easier to see with numbers attached.

Credit relief on one stream of income

Take C$173,000 of income taxed in both countries. Assume the other country charged 31% on it and the home country would charge 26% on the same amount.

Credit relief on one stream of income
ItemAmount
Income taxed in both countriesC$173,000
Tax paid abroad (assumed 31%)C$53,630
Home tax on the same income (assumed 26%)C$44,980
Credit available (lesser of the two)C$44,980
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. That is an illustration of the mechanism, not a prediction about your file — the same computation on your figures is the first thing we do.

These amounts illustrate the mechanism only. The rates and thresholds are assumptions of the example, not your numbers: each is checked against the issuing authority for your specific tax year before any return is filed.

From first call to filed

  1. 1We start with the chronology: dates, countries, and what has already been filed
  2. 2You get the scope and the fee in writing before we touch anything
  3. 3The work is prepared and reviewed by a named person, not a queue
  4. 4Nothing is filed until you have read it

What it costs

The commercial part is deliberately boring. One fixed fee for a written scope, agreed up front in writing — which is what lets us tell you honestly when MLI & the principal-purpose test is smaller than you feared. Comparable engagements and their fixed fees are set out on the pricing pages.

  • A change of scope is re-quoted before the work, never added to the invoice after it.
  • A 24-hour helpline, +1 (416) 619-0068, before you commit to anything.
  • Consultations scheduled to your working day rather than ours.

Your next step

If a letter prompted this, bring the letter — it usually contains the answer to half the questions. Send whatever you have — even an incomplete set. Most of the first hour of an MLI & the principal-purpose test engagement is working out which documents actually matter, and that is quicker with a partial pack than with none.

Reviewed for accuracy for the 2025 and 2026 filing seasons by Udit Gupta, Cross-Border Tax Expert, Legal Quotient Consultants. General guidance only. Your own facts decide the answer, so bring them to a call before relying on this.

Where purpose of tax treaty comes into this file

If you came here for purpose of tax treaty, this is where it is dealt with. The subject is MLI & the principal-purpose test, and the page covers who it reaches, what then has to be filed, and what we charge to do the work.

The multilateral instrument rewrote parts of hundreds of existing treaties at once, which means the treaty text you downloaded is not necessarily the treaty in force.

How the engagement runs, phase by phase

  1. Start with a conversation about the facts

    Dates, residence, where the income arose. Fifteen minutes is usually enough to know what applies.

  2. Scope and price, both written down

    You get the scope and the fixed fee together, so there is no question later about what was included.

  3. Prepared by one team, reviewed by a named practitioner

    The same people see both sides of the file, and the reviewer signs their name to it.

  4. Filed, then followed through

    Submission is not the end of the engagement — the queries that arrive afterwards are part of it.

The vocabulary this page leans on

Second opinion
A review of a filed position, which most often finds an unclaimed credit, a missed information return and an undisclosed treaty position.
Dependent agent
A person who habitually concludes contracts, or plays the principal role leading to them, on behalf of a foreign enterprise — creating a taxable presence without premises.
US estate tax
A tax on the value of US-situs assets at death, reaching non-residents who never lived in the United States, with a much smaller exemption than a US person receives.
Implicit support
The benefit a group member gets from mere association with the group. It is not chargeable, which is why a guarantee fee is priced on the incremental benefit only.
MLI principal purpose test: How we read this one

Its principal-purpose test denies a benefit where obtaining it was a principal purpose of an arrangement, unless granting it accords with the treaty's object.

The engagement terms hold no matter what the analysis finds — fee and scope agreed in writing up front, a named reviewer on the output, your approval before the finished work is filed.

Fixed fees around MLI principal purpose test

Reviewing positions already taken runs differently from testing a structure before it is put in place: the first has to establish what each treaty actually said on every past payment date, since the modified provisions take effect on their own timetable country by country. Both are quoted in writing first.

Why choose Legal Quotient for MLI principal purpose test

Residence is tested, not assumed

Where you are resident for treaty purposes is a question with a method. We work through it and write down the answer, with the facts it rests on.

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.

The order of filing is planned, not improvised

Which return goes first decides whether relief can be claimed at all. That sequence is worked out before anything is submitted.

Late and missed years are ordinary work

An unfiled history is not a reason to wait longer. We assess what is still open and what relief the delay attracts before the first return goes in.

  • Step 1: Send what you already have – Slips, statements, prior returns — in any order. We list what is still needed after reading them.
  • Step 2: A fee agreed in writing – Quoted from those documents, before the work starts, and it does not move once you accept it.
  • Step 3: Each side drafted against the other – The returns are built together rather than in sequence, so relief is claimed once and in the right country.
  • Step 4: You approve before it is filed – The finished return comes to you first. Nothing is submitted on your behalf unseen.

Cross-border tax case studies

Case study 1

Fifteen Per Cent Held Back From a Fee for Services in Canada

A payer must withhold from fees paid to a non-resident for services rendered in Canada, whether or not any tax is ultimately owed. A waiver applied for before the work is invoiced avoids the withholding; after it, the money comes back through a return.

Read how this one runs
Case study 2

The Same Income Taxed Twice on Paper

Relief usually exists and is lost to sequence: one country taxes at source and the other credits it, and preparing them in the wrong order claims a credit against a figure nobody has computed.

Read how this one runs
Case study 3

Deduction at Source on Deposit Interest, Recovered

Where the treaty rate is lower than what was deducted, the difference comes back through a return rather than at source. The file establishes entitlement and files for the years still open.

Read how this one runs
Case study 4

Two Passports, Two Returns, One Income

Dual citizenship does not let you choose which country taxes you. The work is establishing residence, applying the treaty article that governs each income type, and preparing both returns from one set of figures so they agree line for line.

Read how this one runs
Case study 5

Treaty Relief Claimed on a Cross-Border Estate

The estate article can extend a proportionate credit where the two systems would otherwise both tax the same asset. Claiming it requires a valuation and a disclosure the estate may not expect to make.

Read how this one runs
Case study 6

Trips That Added Up to a Filing Obligation

Short visits are tracked against a treaty threshold that is measured over a moving window rather than a calendar year. Where the threshold is passed, the obligation reaches back over the whole period.

Read how this one runs
Case study 7

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 8

A Country-by-Country Report and Who Files It

The obligation sits with the group and the filing can fall on a surrogate where the parent's jurisdiction does not exchange. Establishing who files where comes before preparing anything.

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.

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.

MLI & the principal-purpose test — questions we are asked

MLI & the principal-purpose test — what part of this actually needs a professional?

Some of it, yes — and we will say so on the call if that is the honest answer. The parts that are worth paying for are the ones where a missed election, a missed deadline or an unverified threshold costs more than the fee: its principal-purpose test denies a benefit where obtaining it was a principal purpose of an arrangement, unless granting it accords with the treaty's object.

What if I have already filed and got it wrong?

That is a common starting point. We re-derive the position, identify whether an amendment or a disclosure route is the right vehicle, and tell you which one preserves the relief that is still available. The order matters more than the speed.

How long will it take?

It depends on the documents rather than on us. Once the pack is complete most filings turn around inside a fortnight; anything that needs a certificate from a tax authority runs on that authority's timetable, which we tell you at the start rather than at the end.

What is a totalization agreement and how do I use one?

A social security agreement that stops you contributing to two systems for the same work, and lets periods in both count towards benefit eligibility in either. Which system you stay in depends on the agreement's rules for your situation — a seconded employee usually remains in the home system for a set period, a locally hired one usually joins the host system. You evidence it with a certificate of coverage obtained before or shortly after the assignment starts. See certificates of coverage.

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.

Is my foreign pension taxable?

Usually in at least one country, and which one depends on the treaty article covering pensions — some give the taxing right to the country paying it, others to where you live, and several treat government service pensions differently again. Withholding at source is common and often reducible by treaty, with an elective return recovering an over-deduction. See the pensions article.

How do you decide what is out of scope?

It is written down before we start. Anything not named in the scope is quoted separately rather than assumed, which is what stops the fee moving.

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.
