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.
These words matter because tax systems are not built to line up. One country recognises a structure the other cannot see, and the filing that is routine at home becomes a disclosure obligation abroad. Each page below follows the same shape — definition, consequence, and the specific returns or elections the term reaches.
Most people arrive at a term like this because something arrived in the post. If that is you, the fastest route is to describe the document rather than research the concept. Every page here carries the name of the person who reviewed it and the date they did.
- QEF election — An election to treat a foreign pooled investment as a qualified electing fund, taxing its income currently instead of under the default throwback regime.
- Qualified domestic minimum top-up tax — A local top-up charge that keeps the global minimum tax revenue in the jurisdiction where the low-taxed profit arose.
- Quiet disclosure — Filing amended returns without entering a programme.

Files that look like this one
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 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 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 runsTwo 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 runsSocial Security Contributions Owed in Two Countries at Once
A totalization agreement assigns contributions to one system and exempts the other, but only against a certificate obtained in advance. Without it both sets come out of the same salary and neither is straightforward to recover.
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 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 runsAn Assignee Paid at Home and Taxable Away
Where pay stays on the home payroll but the tax arises elsewhere, a shadow run reports the second country's liability without duplicating the payment. Setting it up correctly is what keeps both sides reconcilable.

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. Licence, subscription and service income are characterised differently by each side, and the answer decides withholding at source, treaty relief and whether a foreign customer creates a taxable presence at all — questions that are cheap to settle before the contract and expensive afterwards.
