How is the fee actually set?
On the first call we establish the scope — countries, years, entities, filings — and quote a fixed fee for it in writing. If the scope changes we re-quote before continuing, and nothing is filed until you have approved it.
Can you work with my existing accountant?
That is how most of these engagements run. They keep the domestic file, we take the cross-border piece, and the boundary is agreed in writing so nothing is done twice or missed.
Who actually signs off on my US and Canadian returns?
A named person, and the same one through the file. The name is on the engagement letter and on the page whose technical content you are relying on. It matters more here than in domestic work, because the two returns are prepared under different rules and often weeks apart, and the only thing holding them together is one person's record of the position taken. If you cannot find out who that person is on a file you have already paid for, that tells you more than any brochure will.
Can the same adviser handle filings in both countries?
The analysis stays with one adviser; the filing itself may involve someone registered in the other country, and if it does you are told who and why. What you should not accept is two advisers each preparing their own side with no shared position on residence, source and credits, because that is how a credit claimed in one country ends up not matching the tax actually paid in the other. Ask directly who owns the joint position. The answer should be a person, not a department, and you should be able to reach them.
I have not filed for years — where does that start?
With facts, not forms. The first work is to establish residence for each year, list the income and accounts that existed, and identify which years actually required a return, because the answer is often fewer than the client assumes. Only then can the route for coming forward be assessed. Arriving at a disclosure with half the years reconstructed is worse than arriving later with all of them, since an incomplete submission tends to reopen the whole period anyway. Bring bank records and immigration documents to the first conversation; they settle more questions than memory does.
Who handles my file in the year I leave Canada?
One adviser should own the whole of that year, because a departure splits it into two tax positions that have to agree with each other. The work is establishing when residence actually ceased on the facts — ties severed, home disposed of, family moved — and then applying the departure rules to that date rather than to the date on the flight. Part-year files are where a second preparer, brought in separately for the other country, most often causes damage: by choosing a different date without knowing one had already been recorded.
How do I check that an adviser is qualified to do this?
Ask for the issuing body and the membership number, and check it on that body's public register rather than on a website. Then ask a second question that matters more: what has this person personally filed in my two countries, and in what role. Cross-border work is learned by doing it, and the failure mode is rarely a missing credential — it is a well-qualified adviser applying a domestic habit to a file that needed a treaty answer. A straight answer to both questions is a fair thing to expect before you engage anyone.
Will my file be passed to a junior after I sign?
Preparation and review are different jobs, and it is reasonable for the assembling of a return to be done by someone other than the person who set the position. What should not change is who answers for it. Ask who reviews the return before it is filed, and whether that is the person you spoke to at the start. The number published on this page reaches the practice directly, and the adviser named on your engagement is the one to ask for. Scope and fee are agreed in writing before any of it begins.
Do American citizens living abroad have to pay taxes?
American expats and green card holders need to file US returns for life, and many of them pay little or no US tax once the relief is applied — but the filing is what unlocks the relief, so the two questions have different answers. The exclusion for foreign earned income, the credit for foreign tax already paid and the treaty between the two countries between them usually leave the total at roughly the higher of the two countries' tax rather than the sum. Skip the return and none of it applies. See Americans abroad.
What is a double tax treaty and what does it actually do?
It is an agreement between two countries that divides up the right to tax. Article by article it decides which country taxes employment income, dividends, interest, royalties, pensions, property and business profits — and where both may tax, it caps what the source country can withhold and tells the other to give credit. It also breaks residence ties and opens a government-to-government channel for disputes. What it never does is apply itself: a treaty position is claimed. See our treaty work.
