Tax Treaties — 2 in-depth guides
What Is a Tax Treaty? Benefits, Claims and Pitfalls
What a tax treaty is, which countries have one with Canada, the US and India, what a treaty benefit actually means, and how to claim it before a payer withholds too much.
Which Countries Have Tax Treaties? The Full Lookup
Yes — and this is the lookup page for the whole chain: which countries have treaties with Canada, the US and the UK, the famous gaps like US–Brazil, and what changes when no treaty exists.
Files that look like this one
A Pension Taxed Where the Treaty Did Not Intend
Pension and annuity articles allocate taxing rights differently from employment income, and a flat withholding often exceeds what a return would produce. The alternative filing is elective and has a deadline.
Read how this one runsA Retirement Plan That Grows Tax-Deferred in Only One Country
Cross-border retirement accounts are recognised by treaty, but the deferral usually has to be elected rather than assumed. The engagement checks whether the election was made, makes it where it was missed, and reports the account on whichever side requires it.
Read how this one runsA Residency Determination Review After Leaving the Country
Residence is decided on ties, not on a form, and the review asks for evidence of every one of them. The file assembles the ties that were severed and the ones that remained, and answers the questionnaire against the treaty rather than around it.
Read how this one runsPaid for Work Done in Canada While Living Elsewhere
Employment carried out in Canada is taxable here even where the employer and the bank account are not. The engagement establishes how many of the days were worked in Canada, applies the treaty employment article, and deals with the withholding the payer has already taken.
Read how this one runsTreaty 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 runsOne Salary, Two Countries Claiming It
A US citizen resident in Canada, taxed in full on both sides because each return was prepared without the other in view. Deciding which country has the first right to the income, then claiming relief on the second return in the right order, is what stops the same dollar being taxed twice.
Read how this one runsA 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.
Read how this one runsInterest and Penalties Put to a Relief Application
Relief is discretionary and is decided on the circumstances that caused the delay, evidenced year by year. The application is built from the same chronology the filings rest on, so the two cannot contradict each other.

Importers, Exporters & Manufacturers
Related-party purchasing, customs value versus transfer price, and foreign-affiliate structures put trading businesses inside the s.247 documentation rules.
Goods crossing a border move the tax question from income to indirect: registration thresholds, place of supply, the customs value and the transfer price between related entities all have to agree with each other. When they do not, the adjustment arrives from two authorities at once and each one uses the other's number.
