Do I have to file at home while living in India?
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 India?
Treaty networks change with each protocol and each multilateral-instrument position, so we confirm the treaty in force for your specific year with the issuing authority rather than relying on a published summary. Where there is none, unilateral relief and domestic law do the work instead.
I own property in India. 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 India offers one, is normally the first thing to check. Your home country taxes the same rent and credits what was paid.
Will my Canadian pension be taxed before it reaches me in India?
Periodic pension payments out of Canada to someone resident abroad are subject to deduction at source, and the payer takes it off before the money moves. The treaty between the two countries can reduce that deduction, but only where the payer holds the supporting documentation before the payment is made. Without it the default treatment applies and the excess has to be reclaimed through a return the following year. Most of the work here is administrative and has to be done with the payer, not with the tax authority.
Are all my pensions treated the same way under the treaty?
No. Payments that look alike to a retiree can fall under different articles, and the article decides which country may tax the payment and on what basis. A company pension, a state retirement benefit, an annuity bought with your own capital and a pension earned in government service are not automatically dealt with alike. The first step in any retirement file is to identify each income stream and place it, before anyone talks about rates. Doing that in the wrong order is how people end up taxed twice.
Does India tax my foreign pension as soon as I arrive?
Not necessarily on arrival. Returning residents pass through a transitional window in which foreign income is not brought fully into the Indian net, and whether you qualify turns on your residence history rather than on your intentions. The window is finite, and pension income that sat outside it becomes taxable when it closes. That makes the timing of large withdrawals, commutations and transfers a planning question rather than an administrative one, and it is worth settling before the first payment is drawn.
Why was my lump sum taxed more heavily than my monthly pension?
Because a single large payment and a stream of periodic payments are often dealt with under different rules, both in the country paying and under the treaty. The reduced treaty treatment that applies to a periodic pension frequently does not extend to a lump sum, and the paying country may deduct more heavily from the one-off amount. Relief may still be available on the return, but it is relief claimed after the event. Ask the question before instructing the plan administrator, not after the payment has landed.
How do I get back the tax withheld on my pension?
By filing in the country that withheld it. The deduction at source is a payment on account, not a final settlement, and where the treaty treatment or the calculation of taxable income leaves you owing less, the return is the route to the difference. What matters is doing it for the right year and with the payer's slips in hand. Refunds arrive long after the year they relate to, and the credit you claim in India is tied to the income, not to the date the money comes back.
Do I still have to file in Canada now that I have retired abroad?
Often yes, though it is a different return. Income with a Canadian source paid to a non-resident may be dealt with entirely by deduction at source, in which case no return is required, but several common streams can instead be reported on a return in order to be taxed on the ordinary basis, which frequently costs less. Property, continuing business interests and the year you actually left all bring their own filings. It is worth having the position set out once rather than decided annually by guesswork.
Does the United Kingdom have a tax treaty with the United States?
Yes — the UK and the USA have one, and so do around sixty other jurisdictions including Canada, India, Australia, Mexico, Brazil and most of western Europe. The existence of a treaty is rarely the useful fact, though. Two people in two treaty countries can get opposite answers on the same pension or the same royalty, because what decides the outcome is the specific article for that income type and any limitation-on-benefits condition attached to it. See our country guides.
How does the treaty tie-breaker work when both countries say I am resident?
As a sequence, stopping at the first test that gives an answer: where you have a permanent home available; if in both or neither, where your centre of vital interests is; then habitual abode; then nationality; and if all of those tie, the two tax authorities decide by agreement. It is evidential rather than elective — you do not choose your treaty residence, you demonstrate it, which makes the record of homes, family and time the substance of the claim. See tie-breaking dual residency.
