Each entry answers two questions — what the term picks out, and what changes once it applies. Neither answer needs a number, and a number in a definition tends to outlive its accuracy.
A surprising share of cross-border trouble is translation rather than arithmetic. The same payment is employment income on one side and something else on the other, and nobody notices until two authorities have both assessed it. That is why each entry ends by pointing at work rather than at more reading: the pages where the term determines an amount or a deadline.
Knowing the term is the first half. Knowing whether it applies to your year, and what evidence proves it, is the half that changes the outcome. Every page here carries the name of the person who reviewed it and the date they did.
- Arbitration clause — A treaty provision allowing an unresolved mutual agreement case to be referred to binding arbitration.
- Annual information statement — India's compiled record of what banks, registrars and brokers reported about a taxpayer.
- Arm's length principle — The standard that a controlled transaction should be priced as it would have been between independent enterprises in comparable circumstances.
- Advance pricing arrangement — An agreement with one or both tax authorities fixing the transfer-pricing method for future years, and in some countries for past ones by rollback.
- Adjusted cost base — The tax cost of property, from which a gain or loss is computed.
- Apportionment — The division of a multi-state or multi-province tax base between jurisdictions by formula, usually on sales, payroll and property.
- Alter ego trust — A trust used to defer the death-year deemed disposition and avoid probate, which can be the wrong structure entirely where a US person is involved.
- Advance ruling — A binding determination of the tax treatment of a proposed transaction, obtained before the transaction is carried out.
- Angel tax — The Indian rule that can treat share premium above fair value as income of the issuing company, resolved by valuation evidence at the time of issue.
- Advance tax — India's in-year collection of tax by instalments, with interest for deferment and shortfall.
- Airdrop — Tokens received without consideration, raising the same timing question as a staking reward: when income arises and at what value.
- Authorised representative — A person authorised with a tax authority to see assessments and slips and to act for the taxpayer — usually where the discrepancies are found.
- Arrival valuation — Documentation of what property was worth on the day residence began, which sets the cost base and cannot be recreated years later.

Cross-border situations we are engaged for
A 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 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 runsAn Adjustment in One Country and No Relief in the Other
A pricing adjustment taxes the same profit twice unless the other country makes a corresponding one. The mutual agreement route is what produces that relief, and it is opened on a timetable set by the treaty rather than by either revenue authority.
Read how this one runsResidency Changed Mid-Year and Both Returns Assumed a Full One
A move part-way through a year produces two part-year positions, not two full ones. The engagement establishes the date residence actually changed, allocates income either side of it, and amends whichever return was filed on the wrong footing.
Read how this one runsThree Countries in One File and Two Treaties That Disagree
Income sourced in one country, paid to a resident of a second, held through an entity in a third: three bilateral treaties, no three-way rule. The analysis works out which pair governs each flow, and whether the middle entity is entitled to anything at all.
Read how this one runsAn Assignment Priced Without Counting the Days
Nearly every relief in a mobility file — treaty exemption, residence, social security — is decided by a day count that has to be evidenced. The engagement puts the tracking in place at the start, because it cannot be reconstructed at the end.
Read how this one runsOne 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 runsInformation Returns Missed Behind a Correct Return
The heaviest exposure on a cross-border file is often a disclosure form rather than the tax. Where the return itself was right, the procedures for late information returns turn on a reasonable-cause narrative with dates and documents behind it.

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.
