Does South Korea tax your Indian income in your first five years?
Not unless you bring it into Korea. Korea sorts foreign residents by how long they have lived there. If you are not a Korean national and you have had a home or residence in Korea for five years or less within the last ten, Korea taxes your Korean income in full, but your foreign income, your Indian FD interest, dividends, rent and capital gains, only to the extent it is paid by a Korean payer or remitted to Korea. This is the rule in Article 3 of Korea's Income Tax Act, and it is close to Japan's non-permanent-resident shelter.
So the practical answer for most Indians in their early Korean years is simple. Leave your Indian income in your Indian accounts, live on your Korean salary, and that Indian income is outside the Korean net. It is only the slice you actually move into Korea that Korea can tax. This is the opposite of what our older Korea note said, and it is worth getting right, because the difference is whole years of Indian income kept out of a 6 to 45 percent Korean bracket.
After five years, Korea taxes your Indian income worldwide
Once you have had a home or residence in Korea for more than five of the last ten years, the shelter ends. From that point Korea taxes you on worldwide income, so your Indian interest, dividends, rent and gains are taxable in Korea whether or not you bring the money in. Korea's national rates run from 6 to 45 percent, and a local income tax adds another 10 percent on top of the national tax, so the combined bite is meaningful.
That five-year line is the planning point. While you are still inside the window, realising Indian capital gains and drawing down Indian income is far cheaper, because Korea only reaches what you remit. After the window, the same gain is fully in the Korean base. If you know roughly when you will cross five years, sequence the big Indian sales and any repatriation before it, not after.
The India side: treaty rate now, Korean credit later
India taxes your Indian income regardless of where you live, so this half is always in play. When an Indian payer credits you interest, dividends or rent, or a fund house redeems your units, tax is deducted under Section 195, which becomes Section 393(2) from FY 2026-27. You bring it down to the treaty rate with a Tax Residency Certificate from Korea's tax office and Form 10F, which becomes Form 41 from FY 2026-27: interest to 10 percent under Article 11, dividends to 15 percent under Article 10. Anything over-deducted comes back through your Indian return.
Where Korea does tax an item, once you remit it or once you are past five years, the India-Korea treaty lets Korea credit the Indian tax you already paid under Article 23, so you are not taxed twice on the same rupee. The one gap is NRE interest: India exempts it, so there is no Indian tax to credit, and if Korea taxes it, on remittance or after five years, it is taxed in Korea in full. That is worth remembering when you choose which Indian income to bring into Korea.

A worked example: Ravi's Seoul years
Ravi, 34, is a data engineer at a Seoul tech firm, three years into his posting, so a foreign resident well inside the five-year window. He holds a ₹40 lakh NRO fixed deposit paying 7 percent, about ₹2.8 lakh of interest a year, plus Indian mutual funds sitting on a gain.
He keeps the FD interest and any redemption in his Indian accounts and lives on his Korean salary. Because he does not remit that Indian income into Korea, Korea does not tax it this year. On the Indian side, he files his TRC and Form 10F so the bank cuts 10 percent, about ₹28,000, instead of the 30 percent default of ₹84,000, and he recovers the rest through his return. If Ravi instead waited until his sixth year, past the window, Korea would tax that same ₹2.8 lakh of interest on a worldwide basis at his Korean marginal rate plus the 10 percent local surtax, giving Korea a credit only for the ₹28,000 of Indian tax. Selling his funds and drawing his Indian income inside the window, while keeping it in India, is what keeps the Korean tax at zero for now.
