The short answer

Double taxation is not prevented by a treaty alone. Three mechanisms do the work: a treaty article that gives one country the exclusive right to tax, a credit for tax paid to the other country, or an exemption.

Who has to deal with this

  • A payer applied a statutory rate where a treaty rate was available
  • You need to prove residence to a foreign payer or authority
  • 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

If more than one of those is true, this is your page. If none of them is, tell us on a call and we will point you at the right one — that happens often enough that we would rather you asked.

Transparent, fixed pricing for how to avoid double taxation

Avoiding double taxation is priced by how many income types and countries are in play, and by whether either return has already been filed. Relief claimed in the right order at the outset is a smaller engagement than the same relief recovered afterwards by amending. The fee is set in writing once your file has been read.

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.

What is really being tested

Double taxation is not prevented by a treaty alone. It is prevented by claiming the right relief, in the right country, in the right order — and the order is decided before either return is prepared.

Three mechanisms do the work: a treaty article that gives one country the exclusive right to tax, a credit for tax paid to the other country, or an exemption. Which applies depends on the type of income, and using the wrong one leaves relief unclaimed rather than double tax cured.

What that means in practice is that the work happens before the filing season, not during it. By the time a return is being prepared the facts are fixed; everything that could have changed the answer — a date, an election, a certificate, a valuation — had its own window, and most of those windows close earlier than people expect.

Where the position depends on a threshold, a rate or a day count, we confirm it against the issuing authority for your own tax year before it goes on a return. Where a figure cannot be verified for your year, we set out the mechanism and quote no number — a wrong threshold on a filed return is worse than an explained one. See also RNOR status — the two-year window and form 8991 — beat.

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

The same point, with figures rather than adjectives.

Credit relief on one stream of income

Take C$167,000 of income taxed in both countries. Assume the other country charged 19% on it and the home country would charge 38% on the same amount.

Credit relief on one stream of income
ItemAmount
Income taxed in both countriesC$167,000
Tax paid abroad (assumed 19%)C$31,730
Home tax on the same income (assumed 38%)C$63,460
Credit available (lesser of the two)C$31,730
Home tax still payableC$31,730

The credit absorbs C$31,730 and leaves C$31,730 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.

Example figures throughout, selected to make the rule visible, with rates and thresholds assumed for the demonstration. Your actual filing uses figures confirmed with the issuing authority for your tax year.

From first call to filed

  1. 1A call to the 24-hour helpline to find out whether this is a filing or a project
  2. 2A fixed fee for a written scope — re-quoted if the scope changes, never invoiced silently
  3. 3Preparation against the evidence, with the positions documented as we go
  4. 4Your approval, then the filing — in that order

What you pay, and when

Pricing works the way it should: a defined scope and a fixed fee agreed in writing before anything starts. If the scope turns out to be larger than we thought, that is a conversation before the work, not a line on the bill. Comparable engagements and their fixed fees are set out on the pricing pages.

  • Fixed fees agreed before any work starts, so the number in the quote is the number on the invoice.
  • We will tell you when you do not need us, and that call is free.
  • Authorisation with each authority, so we see the assessments and slips directly rather than asking you for them.

How to get this moving

We will tell you if you do not need us. That happens more often than you would expect. Start with the dates. Arrival, departure, transaction, notice — whichever applies. Once those are fixed, the filing set and the fee follow quickly, and you will know both before committing to anything.

how to avoid double taxation: The practitioner's note

Three mechanisms do the work: a treaty article that gives one country the exclusive right to tax, a credit for tax paid to the other country, or an exemption.

Whatever the file turns out to involve, the terms do not move: the scope and the fee are agreed in writing before any work starts, a named practitioner reviews the result, and nothing is filed until you have approved it.

The published fees closest to how to avoid double taxation

Evidence is the other thing that moves the price. A credit for foreign tax stands on assessments, payment records and slips from the other country, and where those have to be requested, chased or translated the work grows. The published fees below cover the ordinary shapes of double-tax relief.

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

One Salesperson Abroad, and a Corporate Filing Obligation

A single employee with authority to conclude contracts can create a taxable presence for the whole company. The review tests what the person actually does against the treaty article, and where a presence exists, works out what profit is attributable to it.

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

A Taxable Presence Created Without an Office

A dependent agent habitually concluding contracts can create a permanent establishment where there is no premises at all. The review tests what the person actually does against what the treaty describes.

Read how this one runs
Case study 5

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.

Read how this one runs
Case study 6

Which Country Taxes the Salary

The employment article turns on where the work is done, who pays, and who bears the cost — three tests that can point in different directions. The file establishes all three before either return is drafted.

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.

Case study 8

An Executor Administering Across Two Systems

An executor can be personally liable for what is assessed after a distribution, and the clearance that protects them is obtained rather than assumed. The engagement sequences the filings so the distribution is safe when it happens.

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.

Software revenue crosses borders by default — sourcing rules, withholding on licence-like payments and IP location decide the effective rate.

Software revenue is rarely taxed where the team sits.

How to avoid double taxation — questions we are asked

How to avoid double taxation — how much of this can I do myself?

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: three mechanisms do the work: a treaty article that gives one country the exclusive right to tax, a credit for tax paid to the other country, or an exemption.

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 double tax treaty and what does it actually do?

It is an agreement between two countries that divides up the right to tax. Article by article it decides which country taxes employment income, dividends, interest, royalties, pensions, property and business profits — and where both may tax, it caps what the source country can withhold and tells the other to give credit. It also breaks residence ties and opens a government-to-government channel for disputes. What it never does is apply itself: a treaty position is claimed. See our treaty work.

Do I have to file in both countries?

Frequently yes, and the two filings do different jobs. The country where the income arises taxes it at source; the country where you are resident taxes your worldwide income and then gives credit for the tax already paid. Filing only one side is what leaves relief unclaimed — the credit has to be asked for on a return. We prepare both sides so the numbers agree. See dual filing.

Which kind of investor income is most exposed to double taxation?

Dividends from a foreign corporation. They have already borne corporate tax, the source country withholds on payment, and your residence country taxes the receipt — three layers, only two of which a credit can reach. Interest and royalties carry the same source withholding without the corporate layer. This is why the withholding article and the paperwork that reduces it matter more for portfolio income than for salary. See dividends, interest and royalties articles.

What is the most common thing you find on a review?

An unclaimed foreign tax credit, a missed information return, and a treaty position taken without the disclosure the rules required. Usually all three.

Do you give a written opinion?

Where the position warrants one, yes — with the reasoning, the authority relied on, and what would change the answer. It is quoted as part of the scope rather than added afterwards.
