What makes oil & gas rotational workers different from an ordinary filing?
Rotational work is a day-count problem by design: an equal-time rotation puts a worker in a host country for roughly half the year, which is exactly where residency tests and treaty employment articles turn. 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.
Will I be taxed twice on the same rotation income?
In most cases the income is within reach of both countries, and relief removes the duplication rather than the claim. The country where the work is done may tax the earnings arising there; the country you are resident in taxes your worldwide income and gives credit or exemption for what the other took. That relief is not automatic. It has to be claimed, evidenced and calculated. So the accurate description is that both countries may assess you, and the total should end up close to the higher of the two rather than the sum of them, provided the claim is made properly and on time.
How is my salary split between the host country and home?
Normally by where the work was physically done, which on a rotation means by days. Earnings for days worked in the host country are usually that country's to tax; earnings for days worked elsewhere usually are not, whatever the payslip says or wherever the salary was paid from. Leave, travel and standby time each have to be located before they can be allocated, and the two countries may not locate them the same way. This is why the day log matters. The split is a calculation from it, and without one the allocation is only an assertion.
Which country taxes the leave I accrue between hitches?
It usually follows the work it was earned from rather than where you spent it. Leave accrued during a period of host-country work is commonly treated as remuneration for that work and allocated accordingly, even though you were at home when you took it. Countries differ on this, and some look instead at where you were during the leave itself. Where the two disagree, both may assess the same leave pay, and the answer then comes from the treaty and the relief claim rather than from the payslip. We allocate leave explicitly instead of letting it fall wherever payroll put it.
Does the host country tax me from my first day there?
Sometimes from the first day and sometimes not at all, depending on the treaty and on how long you are present. Many treaties relieve short assignments where the employer is not in the host country and the cost is not borne by an establishment there, but every one of those conditions has to hold, and a rotation that repeats through the year rarely qualifies for long. Domestic law may also impose withholding from the outset regardless of the eventual treaty position. The practical sequence is that tax is often taken first and the treaty position settled afterwards.
My home country taxes worldwide income, what happens to the host tax?
It becomes a claim rather than a cost, if it was properly due. The residence return brings in the full earnings and then relieves the host-country tax, usually by credit, limited to the residence-country tax on the same income. Anything the host country took beyond what the treaty allowed it is not relieved that way. It is recovered from the host country instead. So the host tax splits into two parts with two different remedies, and identifying which part is which is the piece of work that decides your final position in both countries.
Who taxes a bonus that covers a rotation across two countries?
It is generally allocated to the period it rewards, not to the date it was paid. A bonus for a rotation split between two countries is therefore usually apportioned across the days worked in each, on the same basis as salary. Complications arise when the bonus is paid after the rotation ends, in a later tax year, or after you have ceased to be resident somewhere, because the two countries can then place it in different years as well as different countries. We identify the period the bonus relates to first and allocate from that, keeping the workings with the return.
Which country do I pay tax to first?
Generally the source country — where the income arises — taxes first, often by withholding before you receive it. Your country of residence then taxes the same income and credits what the source country took. That order is why timing matters: a residence-country return filed before the source-country tax is settled has nothing to credit yet. Getting the sequence right is most of the work. See international tax planning.
How do families with assets in two countries handle inheritance?
With paperwork built for both systems rather than one. In practice that means wills that work where each asset actually sits, an executor with authority a foreign bank or land registry will accept, clearance certificates before the estate distributes so the executor is not left personally exposed, and an estate tax exposure calculation done while the person is alive and can still act on it. Doing it afterwards costs more and forecloses most of the options. See cross-border wills and trusts.
