Do I have to file at home while living in Oman?
It depends on residence, not on address — except for US citizens and green-card holders, for whom the answer is yes regardless of where they live. We settle the residence question first, because every other answer follows from it.
Is there a treaty between my country and Oman?
Possibly, and the version in force for your year is the one that matters — protocols and multilateral-instrument positions change what a treaty does without changing its name. We check it against the authority rather than a summary. Where no treaty applies, domestic relief takes over.
I own property in Oman. Where is the rent taxed?
Where the property is. That is close to universal, and it usually arrives as withholding on the gross rent rather than as a return on the profit — which is why the election onto a net basis, where Oman offers one, is normally the first thing to check. Your home country taxes the same rent and credits what was paid.
Do I have to file in Canada if Oman has no income tax?
Yes, if you are still resident here, and the absence of Omani income tax makes that question more important rather than less. Where there is no local income tax to credit, nothing offsets the home charge, so the whole outcome turns on whether home residence continued. People move to the Gulf expecting the pay to be untaxed and discover that the only thing standing between them and a full home assessment is a residence position nobody documented. Settle that position in the year you leave, with evidence, because it is the single fact everything else follows from.
My family stayed home while I work in Oman — am I still resident?
That pattern commonly keeps home residence alive, and it is not a technicality. A spouse and children remaining in the family home are significant residential ties in their own right, and they are weighed as facts rather than as intentions. It does not make the answer automatic — the whole picture is considered, and a treaty tie-breaker may apply where the other country also claims you. But a family-split arrangement should be approached on the assumption that home residence probably continued until the analysis shows otherwise, rather than the reverse.
Is my Omani salary tax free if I keep my Canadian house?
Keeping a home available to you is one of the ties that most often decides the question, so the honest answer is that it puts the arrangement at risk. If home residence continues, Omani employment income is reported on the home return and taxed there, and because Oman levies no income tax on it there is no foreign credit to reduce the result. Letting the property on a genuine arm's-length lease is a different fact from leaving it available, but the lease has to be real and the rest of the picture still matters.
How does a rotational schedule affect my residency status?
Rotational work cuts both ways. The time spent at home between rotations often preserves the very ties that keep home residence alive, which is the opposite of what people assume when they count the days spent abroad. On the other side, there may be no local residence to set against it, because the arrangement never established one. The result can be a clear home residence with no offsetting foreign tax at all. Where the rotation is genuinely tied to a residence established elsewhere the analysis differs, so describe the actual pattern, including where you sleep between hitches, before drawing a conclusion.
What happens to my end of service payment from Oman?
A lump sum paid at the end of an Omani contract needs its character established before it is reported. Different elements — accrued leave, a service-related gratuity, severance, a completion award — can be treated differently at home, and the period the payment relates to matters as much as the date it lands. If it is received after home residence resumes but relates to work performed before, the allocation question is live. Obtain the contract terms and the calculation behind the payment, not just the remittance advice, because the calculation is what shows the period and the components.
Do I need to report my Omani bank account back home?
Holding accounts and assets abroad carries reporting obligations that are separate from whether any income arose, and they can apply to balances that never generated a penny of interest. Several distinct obligations may attach to the same account, each with its own test, so an account cannot be dismissed by reference to only one of them. List every account you hold or can sign on, with balances through the year, and apply each test to that list. Accumulated salary sitting in a Gulf account is the asset most often overlooked, precisely because it feels like your own money rather than an investment.
Where does the exclusion go on the return, and does it change my rate?
It is computed on Form 2555 and carried to the return as a negative adjustment to income, so the excluded amount is out of taxable income. It does not, however, pretend you never earned it: the tax on whatever income remains is calculated as though the excluded amount were still there, so the remaining income is taxed at the rates that apply above it. Deductions and credits attributable to excluded income are also disallowed. See the foreign earned income exclusion.
Do green card holders living abroad have to file US taxes?
Yes. A lawful permanent resident is a US tax resident, taxed on worldwide income, and that status does not end simply because you moved away — it ends when it is formally abandoned or administratively terminated. Two traps follow. Filing as a non-resident on a treaty claim can put the immigration status itself at risk. And ending the status after holding it long-term can bring you inside the expatriation regime. See giving up a green card.
