What makes physicians & surgeons different from an ordinary filing?
Physicians moving between systems carry a professional corporation or practice that does not travel with them: the entity remains taxable where it was resident, while the doctor becomes taxable where they now work. 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.
What tax relief do doctors most often miss when working across borders?
The relief that is missed is rarely exotic. It is credit for tax the other country already took, lost because the two returns were prepared by different people in different months and never reconciled. Close behind it is relief for tax borne by the professional corporation rather than by the doctor, which is overlooked because the personal return is prepared from personal documents and the company sits outside that pile. Then there is the treaty, which can restrict what the source country may tax at all and is frequently never read, because the domestic rules alone produced an answer that looked plausible. None of these needs an aggressive position. Each needs the two files to be looked at together.
Can I claim credit for tax my medical corporation paid abroad?
Not directly as a rule, because the company and the shareholder are different taxpayers and a credit normally belongs to whoever bore the tax. What often exists instead is a mechanism that recognises the underlying corporate tax when the profits reach you, so that the distribution is not taxed as though it came out of untaxed money. Whether that mechanism is available depends on your country of residence, on the character of what you receive and on your holding in the company. The practical work is to trace the profit from the company's own return through to the payment in your hands, and to claim on the footing that the two are the same income.
Is it too late to claim relief for a year I have already filed?
Often not. Most systems allow a return to be amended for a period after filing, and many allow longer where the adjustment arises from a foreign assessment that was not final when the original return went in — which is the ordinary situation for a doctor waiting on the other country. A treaty may also provide its own route where taxation contrary to the treaty has occurred, and that route can run past the domestic amendment window. The first step is to establish which years remain open under each rule, because the answer determines whether this is a claim to be made now or a position to be corrected going forward. Do not assume a filed year is closed.
Does the treaty give a doctor relief the domestic rules do not?
It can, in two distinct ways, and they are worth separating. The first is allocation: a treaty can stop the source country taxing certain income at all, or cap what it may take, in which case the correct answer is a reduced liability there rather than a credit at home. The second is resolution: where both countries insist on treating you as resident, the tie-breaking tests produce a single answer instead of two overlapping worldwide claims. The first is the one commonly missed, because a full withholding was accepted at source and then simply credited, when the better outcome was for less to have been taken in the first place.
Why was my foreign tax credit reduced or refused?
Usually for one of four reasons. The tax was not final — a withholding is a payment on account, and the credit is for what the other country was ultimately entitled to take, so an over-withholding recoverable there is not creditable here. The income did not match, because the credit is given against the same income and the two returns described it differently. The periods did not match, so the foreign tax fell in a year in which the corresponding income was not taxed at home. Or the evidence was thin: an assessment or an official certificate is generally wanted, and a payslip is not one. Each of these is fixable, and three of the four are avoidable.
Do I claim relief where I live or where I work?
Both, in a set order, and taking them out of order is what costs money. First look at the country where the work is done and ask what it is entitled to tax, applying the treaty rather than accepting whatever the payer withheld. Reduce or reclaim there if the treaty limits it. Only then turn to your country of residence, which taxes your worldwide income and gives credit for what the source country was properly entitled to take. Claiming a credit at home for an amount the source country should never have taken means you carry the difference, because your country of residence will only relieve what the other one was actually entitled to.
What happens if the two countries disagree about which of them can tax me?
The treaty has a procedure for exactly that. You apply to the competent authority in your residence country, which takes the case up with its counterpart, and the two negotiate a position that removes the double taxation. Some treaties add binding arbitration if they cannot agree. It is slow and it runs on documents, so the practical work is preserving the record and filing protective claims while the clock runs. See our treaty work.
What is double tax relief and how is it given?
Three mechanisms, and which one you get depends on your residence country's law and the treaty. Exemption leaves the foreign income out of the residence-country base. Credit taxes it and then subtracts the foreign tax, capped at the residence-country tax on that income. Deduction merely reduces taxable income by the foreign tax, and is usually the weakest. Canada and the United States lead with credit; several treaties give exemption for specific income types. See claiming the credit.
