These entries describe how a term works rather than what it is worth in a given year. That is deliberate — figures move, and a figure remembered from a definition is the kind that ends up on a return unchecked.
Cross-border vocabulary is mostly a record of disagreement. Two countries look at one arrangement and classify it differently, and the gap between the classifications is where the double tax, or the unintended relief, actually lives. So every entry is written in three parts: the meaning, the point at which it costs something, and the filings on this site that it governs.
If this term has turned up in a letter, a slip or an adviser's email and you are not sure which side of it you are on, that is a short call to the helpline rather than a research project. Every page here carries the name of the person who reviewed it and the date they did.
- Ordinarily resident — A status used in some systems for someone habitually resident in the country, which can limit or extend the income within the charge independently of the residence test.
- OIDAR — India's regime for online information and database access services, taxing a foreign supplier on sales to Indian consumers.
- One-stop scheme — A centralised registration and return arrangement letting a seller account for multiple countries' tax through a single filing.
- ODI — Overseas direct investment from India, which brings annual performance reporting for the life of the investment.
What the O entries have in common
4 terms begin with O. Follow the entry itself for the mechanism, the filings it decides, and the fixed fee attached to that work. Three to start with: Ordinarily resident, OIDAR and One-stop scheme.

Files that look like this one
Scope of charge settled where residence and ordinary residence diverged
A client had returned to a country after a long period abroad and had been told, correctly, that they were resident again. What had not been considered was the second layer, which affected how much of their foreign income fell within the charge and for how long. The work consisted of establishing the date each status was acquired under that country's own rules, mapping the foreign income streams against those dates, and identifying which were inside the charge in the year of return. The engagement produced a return filed on that basis and a schedule of when the treatment changes.
Digital services supplier reviewed for an Indian registration obligation
A company outside India had built an Indian customer base without ever considering an indirect tax obligation there. The work consisted of classifying what was actually supplied and how it was delivered, splitting the customer base between registered businesses and private consumers, and establishing which supplies carried the obligation for the supplier rather than for the recipient. The engagement produced a written conclusion on whether registration was required, the evidence of customer status behind it, and a process for checking new customers at the point of sale rather than at the year end.
Habitual residence evidenced across a long overseas assignment
An individual on an extended assignment abroad was treated by their home country as still habitually resident there, and the assessment reflected it. The work consisted of assembling what the status actually turns on in that system. Where a home was kept and whether it remained available, where the family lived, the pattern and purpose of return visits, and how settled the arrangement abroad had become. The engagement produced a documented position with the underlying records attached, correspondence with the authority setting it out, and an agreed filing basis for the remaining years of the assignment.
Subscription income characterised before an Indian withholding decision
An overseas supplier's Indian customers were deducting tax from subscription payments on one characterisation while the supplier had contracted on another. The work consisted of reading the contract against what was actually supplied, establishing which category of income the treaty places that payment in, and setting out whether the deduction being taken was consistent with it. The engagement produced a written characterisation with its reasoning, a position agreed with the customers for future invoices, and a claim for the amounts already deducted above the entitlement.
Return to the home country planned before the arrival date was fixed
A client intended to move back and had assets and income streams built up while away. The question was what would fall within the charge from the day of arrival and what would follow later. The work consisted of setting out how residence and the second layer are each acquired in that country, identifying the income and gains affected by each, and testing what a different arrival date would do to the answer. The engagement produced a written timetable, a set of actions to complete before arrival, and a filing plan for the first year back.
Two countries applying different residence concepts to one year
One authority applied a day count and the other applied a habitual residence concept, and both concluded that the same individual belonged to them for the same year. The work consisted of establishing each country's answer on its own terms, then applying the treaty between them to decide which held the primary right and what relief the other had to give. The engagement produced a residence conclusion evidenced from tenancy, travel and employment records, returns filed consistently on both sides, and a note of the tie breaker step on which the conclusion actually rested.
Green Card Kept, Moved to Canada — Both Returns Still Due
Holding a green card does not end the US filing obligation, and living in Canada starts a Canadian one. The engagement fixes residence under the treaty tie-breaker, then decides which return the relief is claimed on so the two do not contradict each other.

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.

Performance income is taxed where earned — Regulation 105 in Canada, withholding agreements in the U.S. — with special treaty articles overriding the usual rules.
Performance income is taxed where the performance happens, and the deduction is usually taken at source on the gross fee before expenses. Recovering the difference is a filing exercise in the other country, and it only works if the tour, the residency and the withholding certificates were documented while the work was being done.
