I moved from India to Australia mid-year, do I file in both?
Usually yes, and that is the ordinary outcome rather than a sign something has gone wrong. A move splits the year: each country tests your residence on its own terms and for its own tax year, and each taxes the part of your income its rules reach. India looks at your presence in the departure year; Australia looks at the position you take on arrival. Because the two systems ask different questions about the same twelve months, the same income can fall into both returns, and relief comes from claiming credit for tax paid on the other side rather than from filing once. Plan the order of the two filings before either is submitted.
Does a tax treaty mean I only file one return?
No. A treaty allocates taxing rights between two countries and limits double taxation; it does not merge two filing systems into one. You remain within both administrations, and in most cross-border years you file in both. The treaty does its work inside those returns, by deciding which country may tax a given category of income and by supporting the credit or exemption claimed on the other side. Treating a treaty as a reason not to file is one of the more expensive misunderstandings in this corridor, because the obligation continues quietly while the position that would have protected you is never actually claimed.
Is my Australian superannuation taxed in India when I move back?
It depends on your Indian residence position for the year and on how the fund and its growth are characterised, which is not the same question in both countries. A preserved retirement fund can be treated as a pension arrangement on one side and as an ordinary investment asset on the other, and the year in which growth is recognised may differ. That divergence, rather than the rate, is what causes the trouble. Settle the characterisation in writing before you draw anything, and before the first Indian return after your return, because positions taken by default in the first year are difficult to unwind later.
Do I have to declare my Indian flat to the Australian tax office?
If you are resident in Australia for the year, its system reaches your worldwide income, so rent from an Indian property is reportable there even though the property and the tenant never leave India. The Indian side taxes it as income arising in India. The same rent is therefore reported twice, and relief comes from claiming credit for the Indian tax against the Australian liability on that income. Keep the Indian tax records in a form that supports a credit claim, by income category and by country, since a claim that cannot be evidenced is the usual reason the relief is lost.
I am moving back to India from Australia, what changes in my first year?
The first year back is the one written by special rules rather than general ones. India has a transitional residency window for people returning after a period abroad, during which the treatment of foreign income and foreign assets is not the same as it will be once you are fully resident again. There is also a foreign-asset disclosure obligation that attaches to Indian residents and catches accounts, funds and holdings left behind in Australia. The practical point is that the window is finite and the order of transactions matters, so decisions about selling, transferring or drawing on Australian holdings should be taken before the status changes, not after.
What happens if I sell my Indian property while resident in Australia?
Two computations of one gain. India taxes it because the property is there, working from its own rules on cost and on the period of ownership. Australia taxes the same disposal because you are resident and taxed on worldwide income, and it computes the gain under its own rules, which need not produce the same figure or fall in the same reporting period. Relief comes through a credit for the Indian tax, and the credit is only as good as the matching between the two computations. Settle the Indian position, and the records behind the cost, before you sign anything rather than at filing time.
Do NRIs have to file an Indian tax return?
If you have Indian-source income above the filing threshold, or you want a refund of tax withheld at source, or you are claiming treaty relief — then yes. Interest, rent, capital gains on Indian shares or property, and TDS deducted at a rate higher than your real liability all commonly force or reward a return. Filing is also how a lower-rate treaty claim and a foreign tax credit get onto the record. See NRI tax return filing.
What are Form 15CA and Form 15CB?
They are the certification pair required before certain remittances leave India. Form 15CA is the remitter's declaration filed online; Form 15CB is the accountant's certificate supporting the tax treatment and the rate applied, including any treaty relief. Which combination you need depends on the nature and size of the payment, and banks will generally not process the remittance without them. See Form 15CA.
