What the ten-year rule actually says
It is narrower than the rumour and wider than people expect once they read it.
Sweden may tax a former resident's gain where two conditions both hold: the person was tax resident in Sweden in the year of disposal or in one of the ten preceding calendar years, and the securities sold were acquired during the time they were resident. Sell in year eleven, or sell something you bought after you left, and the rule does not bite.
The part that catches Indians is the second condition. If you opened the demat account or bought the stock while you were in Stockholm, it was acquired while you were resident, whatever the money's origin and wherever the company sits. An Indian company is a foreign business from Sweden's point of view, and that is precisely what the rule is written for.
Does the India-Sweden treaty cancel Sweden's ten-year rule?
The ten-year rule is Swedish domestic law, and the India-Sweden treaty cuts its real window down to four years.
Article 13(6) is the paragraph nobody quotes. Where an individual has been a resident of one state and has become a resident of the other, the first state may still tax a gain if the sale happens within four years of the date they ceased to be resident there. For someone who has left Sweden and become Indian resident, that is Sweden's actual reach: four years, not ten.
What governs a sale after that is Article 13(5). Gains outside paragraphs 1 to 4 are taxable only in the state where the seller is resident, provided that resident is subject to tax on them there. If they are not subject to tax, the other state may tax them after all, so the residence limb is not unconditional.
Article 13(4) is the exception that hands a gain back to India: shares of a company whose property consists directly or indirectly principally of immovable property. Ordinary Indian company shares are not that, which is why they fall to 13(5) in the first place.
| When you sell | Paragraph | Who can tax |
|---|---|---|
| Within four years of ceasing Swedish residence | 13(6) | Sweden may still tax |
| After four years | 13(5) | Your residence state alone, if subject to tax there |
| Shares of a property-rich company | 13(4) | India may tax |
Why the Indian side does the real work
Everything above turns on facts only Indian records hold, and that is the part a Swedish adviser cannot produce for you.
When you acquired each holding, which decides whether it was acquired while you were Swedish-resident at all. What your Indian residential status is now, which decides whether the treaty's residence limb points at India. Whether the gain is genuinely subject to tax in India, because the residence limb of Article 13(5) turns on exactly that. And what India has already taken at source, because a gain can be withheld against in India and claimed in Sweden in the same year with nothing lining up.
That is the file: the acquisition history per holding, the residence position with the evidence behind it, and the Indian tax actually borne. Assembled properly it answers the Swedish question. Assembled badly it invites both revenue authorities to assume the worst.
The sequencing trap, which costs more than the rule itself
Sweden's filing deadline falls before India's. That single fact has cost people real money.
What happens is this. The Swedish return is due, the gain gets declared and taxed in Sweden, and only later does the person look at the Indian side and try to relieve the double tax there. At that point they find that the Indian mechanisms for crediting foreign tax, Form 67 and the Schedule TR in the return, are built for a person resident in India. A non-resident does not have them.
So paying Sweden first and expecting India to give it back is not a plan, it is a dead end that then has to be unwound on the Swedish side instead, which is slower and needs a reason. Working out the order before either deadline is cheaper than fixing it after one has passed.
