What makes airline pilots different from an ordinary filing?
Most treaties have a dedicated rule for crew of aircraft in international traffic, which can hand taxing rights to the country of the employer or of the enterprise's management rather than to the country you flew over. That single article is why a pilot's return does not follow the ordinary employment rules. An ordinary preparer applies the general rule and stops there, which is how the relief in the specific provision goes unclaimed.
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.
Does my base decide which country taxes my salary?
No. The ordinary rule in the employment article follows where the duty was physically performed, which would split a roster across every country on it. Most treaties displace that for crew of aircraft in international traffic, and that rule can point instead at the country of the employer, or of the enterprise's management. Which limb applies is read off the treaty between the two countries in question. The base is not one of those limbs, even though it is usually what decides where payroll deducts.
Do layover days count towards residency in the countries I night-stop in?
They can, and the test differs in each one. A presence test counts days, not reasons — nobody asks whether you were working, sleeping or waiting for a return sector — and countries differ on whether time spent purely in transit counts and on how a part-day is treated. Treaty residence is settled separately, on where your home and family life sit, so a country can count you as present without becoming your country of residence. A day tracker is where this starts, not where it ends.
My airline will not apply the treaty and withholds anyway — what now?
Payroll deducts on the employer's own registration and default rules. It is not where a treaty position gets decided, and most departments have no mechanism for accepting one. Relief is claimed by you rather than granted by them: on the return in the country the treaty leaves the taxing right to, or through the other country's refund or waiver route where one exists. It is a cash-flow problem before it is a tax problem, so the order the two returns are filed in matters.
Nothing comes off my pay at source — will I owe instalments?
Whether anything is deducted turns on where your employer is registered to run a payroll, not on where the roster takes you, and the country the crew article leaves the taxing right to is not always the one running that payroll. Where nothing comes off at source the whole liability arrives at filing, and instalments follow from the arithmetic rather than from the airline. In Canada, for the 2026 tax year, the test has two limbs: net tax owing above the published threshold in the current year and in either of the two preceding years, with a lower threshold for residents of Quebec. That structure is why a first year on a foreign contract often produces none and the next one does.
Can I exclude my salary as foreign earned income?
This is a United States question, and the annual cap is rarely what decides it for a pilot. The exclusion reaches foreign earned income — pay for services performed in a foreign country — and you have to meet either the bona fide residence test or the physical presence test before any of it is available. The hard part is the apportionment: establishing which duty time was performed in a foreign country and which was not. That comes off the roster rather than the payslip, and it is the part an examiner asks to see.
Do I have to report the bank account at my base?
If you file a United States return, reporting keys off the account rather than off whether tax is owed, and two separate regimes run on separate thresholds: the FBAR, which is filed with FinCEN rather than attached to the return, and the FATCA asset statement. The one that catches crew is the asset statement's living-abroad test, which unlocks the higher thresholds. It measures physical presence in a foreign country, which for a pilot is not the same thing as time spent away from home.
Do I get credit for all of the foreign tax I paid?
Only up to your own country's tax on that same income, and only for tax you were legally obliged to pay. Two consequences follow. Living somewhere that taxes you more heavily than your residence country does leaves an excess that becomes a carryover rather than a refund. And withholding suffered above the treaty rate is not creditable — the route back to that money is a refund claim in the country that took it. See claiming the credit.
I work remotely from another country for a company back home — who taxes me?
Usually the country you are physically in, because employment income is generally sourced where the work is done, with your residence country taxing it as well if you are resident there and giving credit. Three things follow: your employer may acquire withholding and social security obligations where you sit, a treaty tie-breaker may be needed if both countries call you resident, and a short trip that becomes a long stay can cross a residence threshold nobody was watching.
