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

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 2

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.

Case study 3

A Foreign Affiliate Return Filed Years Late

The reporting obligation on a company held abroad runs separately from the corporate return and carries its own exposure. The work is reconstructing the surplus position across the open years before any filing goes in.

Case study 4

A Foreign Subsidiary That Nobody Had Been Reporting

Owning a company abroad triggers an information return separate from the corporate return, with its own penalty. The work is the surplus and income computations behind it, which also determine how a future dividend is taxed on the way home.

Case study 5

Years Filed Quietly, and What That Cost

Posting missing returns without taking a view on the route gives up the certification-based protection and can itself be read as an indicator. The first task on these files is mapping which years remain eligible for which route.

Case study 6

Social 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.

Case study 7

Three Account Types, Three Tax Answers

Interest on each is treated differently and the deduction at source follows the account rather than the person. Holding the wrong one for the purpose is a recurring and avoidable cost.

Case study 8

Accounts Reported Late When the Income Already Was

Where the income was on the return and only the account report was missed, a narrow route allows late filing with a reason attached. It is open only while no income is unreported and no examination has begun, which is why it is checked first.

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.
