Iceland has no master file, at least not by that name. Groups arriving with an OECD-shaped two-tier file find the labels do not exist in Icelandic law, and the real deadline is not a date at all: it is 45 days from whenever the tax authority asks.
The four facts to know:
- There is no OECD-format master file requirement. The same group-level information is required, in Iceland's own format.
- Documentation is prepared for each financial year, kept, and produced within 45 days of a request. Nothing is filed with the return.
- Keep it for 7 years from the end of the financial year.
- Failing to produce it costs up to ISK 3 million per financial year, capped at ISK 6 million in total. Fixing the gap within 30 days cuts the fine by 90%.
What transfer pricing documentation does Iceland require?
Local transfer pricing documentation, prepared for each financial year and held until Iceland Revenue and Customs asks for it. Equivalent group-level information is required too, but not on the OECD master file template. The OECD transfer pricing country profile for Iceland[1], updated in January 2026, confirms that Iceland makes no legislative distinction between a master file and a local file.
Two obligations run in parallel and groups often collapse them into one. Every related-party transaction has to be priced at arm's length, whatever its size. The documentation duty is separate, with its own content and its own timing. Pricing correctly does not discharge the documentation duty, and documenting thoroughly does not fix a price that was never at arm's length.

| Master file | Not required in OECD format. Equivalent group information is required | OECD |
| Local documentation | Required, per financial year, kept 7 years, produced within 45 days of a request | OECD |

Do I need a master file in Iceland?
Not in the OECD format. The documentation regulation requires equivalent group-level information in another shape, and the OECD labels are not statutory in Iceland. The practical answer for most groups is that a centrally prepared master file will carry the content Iceland wants, but it is the content that is required, not the template.
The reason is timing. The documentation regulation published in the Icelandic regulations register[2] was issued on 23 December 2014 and took effect on 1 January 2015. The OECD's final report on documentation landed in October 2015. Iceland wrote its content requirements first, so the later labels never entered the law.
Who do Iceland's transfer pricing rules apply to?
Parties related by majority ownership or control, which means 50% or more, held directly or indirectly. Members of the same group count. So do two entities majority-owned or controlled by individuals connected through family ties: spouses, registered partners, siblings, parents, grandparents and children.
The arm's length duty catches every related-party transaction regardless of size. The documentation duty is where a threshold would sit, and no monetary documentation threshold is confirmed from a primary source. The figure of ISK 1 billion circulates widely and is not verifiable, so this page does not state a threshold rather than repeat an unverified one.

What are Iceland's local file requirements?
One consolidated set of documentation per financial year, covering the Icelandic entity's related-party transactions, produced within 45 days of a request and kept for seven years from the end of that financial year. There is no separate OECD-format local file, because there is no OECD-format master file to separate it from.
Minor transactions of limited economic scope and importance are exempt from documentation, though they still have to be reported. That exemption never reaches transactions involving intangible assets, whatever their size. An intangible is documented in full, every year.
Does Iceland require country-by-country reporting?
Yes. The report is due no later than 12 months from the end of the financial year, in English, on a set form. The country-by-country regulation published in the Icelandic regulations register[3] is the rule behind it.
The filing threshold and the notification rule are not confirmed from a primary source. The EUR 750 million figure used across the OECD is the obvious candidate, but this page does not assert it as a settled Icelandic number.

Does Iceland have a transfer pricing form or filing?
No. There is no transfer pricing form. You give a confirmation with the annual tax return that the documentation exists, and the documentation itself stays with you. Nothing goes to Iceland Revenue and Customs[4] until it asks.
Once it asks, the 45 day clock starts, and it does not stop for a benchmarking study you have not run yet. The whole design assumes the file is already written. Forty-five days is enough to send a document. It is not enough to build one.
When is Iceland transfer pricing documentation due?
Within 45 days of a request, which is the only deadline attached to the documentation itself. The country-by-country report has a real date: 12 months from the financial year end. Retention runs for seven years from the end of the financial year.

| Country-by-country report | 12 months from the financial year end | Government of Iceland |
| Confirmation that documentation exists | With the annual tax return | OECD |
| Retention | 7 years from the end of the financial year | OECD |
What language must the documentation be in?
Icelandic or English, or both. The country-by-country report has to be in English on a set form. A group that prepares its group-level file centrally in English can use it in Iceland without translation, which is one of the few places the Icelandic regime is easier than its neighbours.
What are the penalties for getting Iceland transfer pricing wrong?
Administrative fines of up to ISK 3 million per financial year for failing to produce documentation within 45 days, capped at ISK 6 million across up to six income years. The fines have been in force since 2021. Fixing the problem quickly cuts them sharply, and the discount scale is steep enough to be worth planning for.

What is a foreign parent exposed to in Iceland?
Adjustments where the documentation is absent or thin, assessments reopened up to six years back when new information emerges, and no way to buy certainty in advance. Iceland runs no advance pricing agreement programme. The mutual agreement procedure under its treaties is the only route, and it resolves disputes after the fact rather than preventing them.
That missing programme changes the defensive posture. In a country with advance agreements, a group can settle its method with the tax authority and stop worrying. In Iceland the only equivalent is documentation that is complete, current and sitting ready when the request arrives.
How do Iceland's rules differ from the OECD baseline?
Iceland follows the OECD Transfer Pricing Guidelines, and diverges in four concrete ways. Three of them cost you work. The fourth, the interest cap, is a limitation on deductions rather than a transfer pricing rule, and it catches groups funding an Icelandic entity with related-party debt.

| Feature | Iceland's position | Source |
|---|---|---|
| Master file and local file labels | Not used in law. Equivalent content is required instead | OECD |
| Safe harbours | None in law. Low value-adding services are accepted in practice, following the Guidelines | OECD |
| Related-party interest | Deduction capped at 30% of earnings before interest, taxes, depreciation and amortisation, once net related-party interest passes ISK 100 million | OECD |
| Advance pricing agreements | No programme. The mutual agreement procedure only | OECD |
How we help with Iceland transfer pricing
Iceland asks for documentation that is already finished, in a format its own rules describe rather than the OECD's. We map your group's content onto what Iceland actually requires, run the benchmarking behind the arm's length position, and keep the file current so the 45 day window is a formality. See how our transfer pricing software works.
