Free e-book library — 21 guides

Each guide is a full read rather than a teaser: what the rules are doing, the order the work happens in, the documents to gather, and where it goes wrong. They are published on this site rather than gated behind a download form, so there is no email address to give and nothing to install.

How these guides are written

Mechanisms, not numbers

None of these guides quotes a rate, a threshold, a statutory section or a day count. That is deliberate. A figure is right for one tax year and wrong for the next, and a guide that leans on one goes stale without anybody noticing. So each guide explains what the rule is doing and names the form it is done on — a form number is something you can look up — and the current figure for your own tax year is confirmed against the authority that publishes it before anything is filed.

Where you want a number now, the cross-border calculators and the individual service pages carry them, and the glossary defines the vocabulary the two revenue authorities use without explaining.

Written for the reader who has the problem

Every guide is aimed at somebody in a specific situation rather than at a search engine: the person who has already left Canada, the founder whose first US customer just paid, the executor holding two sets of forms. Each one opens with who it is for, so you can tell in a sentence whether to keep reading.

If you would rather ask than read, the helpline answers 24 hours a day on +1 (416) 619-0068. Fees are fixed and agreed in writing before any work starts — see every published fee or contact us.

Free to read and free to share in full. Nothing here is advice on your own situation: it describes how the rules work, and your facts decide the answer. Two longer references sit beside this library at the same level — the global transfer pricing guide and the global tax treaty guide — and for the rest of what this site publishes, see all free resources, the answers library and the document checklists.

What these engagements turn on

Case study 1

A reader who arrived with the departure guide half worked through

Someone leaving Canada had read the departure year guide, listed their assets and stopped at the deemed disposition. The work started from their own list rather than from a blank page, which shortened it considerably. Holdings were sorted into what is deemed disposed on departure and what is excluded, valuations were obtained for the items that needed them, and the elections available to defer were weighed against the security they call for. The engagement produced the departure return, a schedule of values as at the departure date, and the election paperwork filed with it.

Case study 2

Choosing a structure after reading the business and structure guides

A founder with customers in two countries had read through the business and structure section and arrived with the right question rather than a preferred answer. The work was to test the options against their actual facts: where the work would be performed, where the customers contract, which entity would hold the intellectual property, and what each choice would cost in annual compliance. The engagement produced a written comparison of the structures considered, a recommendation with its reasoning recorded, and a registration and filing calendar for the structure that was chosen.

Case study 3

An unreported account found by a reader of the disclosure guides

A reader working through the reporting and disclosure guides recognised an account they had never mentioned to anyone. The first task was establishing the span of years affected and whether the income had in fact escaped tax, because the reporting failure and the tax position are separate questions with separate consequences. Statements were requested from the institution and the income was recomputed for each year. The engagement produced amended returns, the outstanding information reports, and a submission explaining how the omission arose, prepared before any approach was made to the authority.

Case study 4

An executor sequencing two countries after reading the estates guide

An executor had read the estates and inheritance material and understood that the order of the filings mattered, but not what that order was for this particular estate. The work was to map every asset to the jurisdiction that would tax it, fix the dates each filing runs from, and identify which return had to be settled before another could claim relief for the tax it paid. The engagement produced a filing calendar for the estate, the returns prepared in that sequence, and a note to the beneficiaries setting out what remained outstanding.

Case study 5

A secondment set up from the payroll and mobility guide

A business sending an employee across a border had read the payroll and mobility guide and knew that a certificate has to be obtained in advance, which is the part most callers have already missed by the time they telephone. The work was the application itself, together with payroll instructions for both entities so that contributions and withholding stopped in one place and started in the other on the same date. The engagement produced the certificate, written payroll instructions for each side, and a note covering what happens if the secondment is extended.

Case study 6

From the transfer pricing guide to the local file itself

A finance director had read the transfer pricing guides and recognised the arrangement described in them as their own. The conversation could therefore begin at scope rather than at explanation. The transaction types were listed, the entity to be tested was agreed, and the level of defensibility required was settled before a fee was set. The engagement produced a functional analysis, a benchmarking search with its rejection reasons recorded as they were made, and a local file covering the year in question, with the working papers kept for a refresh the following year.

Case study 7

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.

Case study 8

Ten Years of Missed Returns Filed as One Engagement

Filing many years at once is a sequencing problem: carry-forwards, instalments and credits from the earliest year feed the latest. Filing them out of order is what turns a recoverable position into an assessed one.

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.

Global E-commerce & Marketplaces

Cross-border tax for sellers shipping worldwide: marketplace withholding, foreign registrations and inventory nexus handled before they become audits.

Marketplaces withhold, remit and report in their own right, so the tax position of a single sale is decided by where the stock sat, where the buyer was and which platform collected — not by where the company is registered. We reconcile the platform's own filings against the returns before either is submitted.
