Norway credits the treaty rate, not what your bank deducted
Norway will credit 10%, no more, whatever your bank took. Skatteloven 16-27 stops Norway giving a deduction for more than the treaty obliges it to give, and the treaty caps Indian tax on interest at 10% of the gross amount where you're the beneficial owner (Article 11). Dividends are capped at 10% too (Article 10).
What India actually takes, absent treaty paperwork, is the domestic rate under Section 195 (Section 393(2) from FY 2026-27). On NRO interest that's 30% plus a 4% health and education cess, so 31.2% where no surcharge applies. The 21 points between 31.2% and 10% are stranded, and Skatteetaten cannot credit them.
The cheaper route is not to lose the money in the first place. File a residence certificate from Skatteetaten with Form 10F (Form 41 from FY 2026-27) at your bank before the interest is credited, and the deduction drops to the treaty rate at source. Your bank will normally also ask for a beneficial-ownership and no-permanent-establishment declaration, which is its own due diligence rather than a statutory condition.
Your Oslo mortgage sets a second limit on the credit
A large Norwegian mortgage shrinks the Indian credit you can claim. Three rules stack:
1. FSFIN 16-29-4. Your deductible Norwegian debt interest is allocated between Norway and abroad in proportion to where your net income sits, so part of the mortgage interest is attributed against your Indian income. That shrinks the Norwegian net foreign income, and with it the maximum credit. The carve-outs turn on business carried on in another EEA state, or on 90% or more of the debt interest being tied to business in or outside Norway, and neither reaches an ordinary corridor reader. 2. Skatteloven 16-21. The credit is capped at the share of your Norwegian tax falling proportionately on the foreign income. Where Norway's tax on that slice comes to less than the Indian 10%, the difference goes unrelieved. 3. Skatteloven 16-22. What's left over carries forward five years, and Indian interest and Indian dividends sit in the same income category, so they pool against each other.
The one-year carry-back in that last provision reads well and rarely helps. It's conditional on showing you won't be taxable in Norway on that foreign-source income for the next five years, and if your NRO account is still earning, you can't show that.
Why your dividends go through and your NRO interest sticks
Dividends go through because the withheld amount is the whole story. NRO interest sticks because what you're claiming is usually not what was withheld.
| Your Indian income | What Skatteetaten wants | Why |
|---|---|---|
| Dividends taxed at the treaty rate | The deduction certificate showing tax withheld at payment | Skattedirektoratet accepts this for a treaty withholding tax, with no final assessment needed |
| NRO interest deducted at 31.2% | The final Indian tax, evidenced by the processed return | You're claiming a different figure from the one withheld, so the finality test bites |
The underlying rule is skatteloven 16-20, which gives credit for foreign tax that is finally assessed and shown to have been imposed on you and paid. FSFIN 16-29-8 sets the proof: that the amount is creditable foreign tax, that it was paid to the foreign state, and that it's final tax on an ordinary assessment there. Skattedirektoratet adds that a provisional determination isn't enough, an ordinary assessment has to exist, and appealing it doesn't postpone your right to the credit.
Indian TDS is a withholding tax, so on its face the relaxation reaches it. It stops working the moment you were over-deducted, or you're claiming the treaty rate against a domestic-rate deduction, or you have a refund coming. Your Indian return is the only thing that settles those.
Six months from the Indian assessment, not the Norwegian deadline
You get six months from the date India finally assesses the tax. Skatteloven 16-25 sets two limbs. The claim must be made before the deadline for filing the skattemelding for the year the foreign income was taxable in Norway. Or, where it can't be substantiated by then, no later than six months after the tax was finally assessed abroad. There's an outer wall at ten years from the end of the Norwegian year the income was taxable in.
That six months runs from the Indian assessment date, not from the day you get round to looking at it, so an Indian refund left to sit can quietly close the Norwegian window.
FSFIN 16-29-3 handles the year mismatch. Where you're taxed abroad on a different tax year, the credit is limited to the proportionate part of the foreign tax matching the share of foreign net income earned inside the Norwegian year. And FSFIN 16-29-11 obliges you to tell Skatteetaten if the foreign assessment later changes so that the foreign tax is reduced. An Indian refund arriving two years later is a reportable event, not a windfall.
The India-side sequence the Norwegian rule forces
File the Indian return early, not at the deadline. Everything else follows from that.
1. Keep the intimation the department issues when it processes your return under Section 143(1). That's the document evidencing your final Indian tax. It isn't an assessment order and shouldn't be described as one. 2. Pull Form 26AS (Form 168 from FY 2026-27) and the AIS, and the Form 16A the bank issues (Form 131 from FY 2026-27), then reconcile tax deducted, tax finally payable and refund received. 3. Recut those April to March figures across the two Norwegian calendar years they straddle. 4. Claim the Indian refund of everything India took above the treaty rate. 5. Diary the six-month date from the Indian assessment.
The generic version of this timing problem, for every country rather than Norway, sits on why your foreign tax credit lands in the wrong year.
Where Kavita's Indian TDS actually lands
Kavita loses Rs 84,800 to a form she never filed, and only India can give it back.
She lives in Oslo and earns Rs 4,00,000 of NRO fixed deposit interest in an Indian financial year. Her bank has no treaty paperwork on file, so it deducts at 31.2%, which is Rs 1,24,800.
The treaty lets India take 10%, or Rs 40,000. Norway credits up to that Rs 40,000 equivalent, capped further by the Norwegian tax on the same interest, which at 22% on Rs 4,00,000 is around Rs 88,000, so the Rs 40,000 fits comfortably inside the cap.
The remaining Rs 84,800 never becomes a Norwegian credit. Had she filed her residence certificate and Form 10F with the bank first, the deduction would have been Rs 40,000 from the start and there would have been nothing to chase.
