A foreign registration does not settle where a company is taxed
Article 2 treats a legal entity as resident where registered in Iceland, domiciled there under its constitutional rules, or actually managed there. A nonresident business may separately have Icelandic-source or permanent-establishment exposure. Identify who makes substantive decisions and where the activity occurs before choosing an entity.
| Issue | What it means | Action |
|---|---|---|
| Incorporation / constitutional domicile | Icelandic registration or domicile can establish residence. | Review the entity’s governing documents. |
| Actual executive management | Foreign incorporation can coexist with Icelandic management. | Map directors, authority, strategic decisions and the operational evidence. |
| Permanent establishment | A separate source-tax analysis for a nonresident enterprise. | Review people, premises, agents, contracts and treaty terms. |
2026 company rates depend on the entity
The ordinary rate for qualifying limited-liability companies is 20% under Article 71. Other separately taxed entities can fall within 37.6%. These are entity-level rates; salary, dividends and shareholder-level consequences still require their own calculation. The temporary 2024 company surcharge is not the ordinary 2026 rate.
| Issue | What it means | Action |
|---|---|---|
| Qualifying limited-liability company | 20% ordinary taxable profit | Determine Icelandic classification of the actual legal entity. |
| Certain separately taxed partnerships and other entities | 37.6% ordinary taxable profit | A partnership name does not establish transparent treatment. |
| An owner working in the business | Remuneration, pension and payroll rules | Company profit is not a substitute for an employment-cost model. |
| Distribution to a shareholder | Separate recipient and withholding analysis | Compare retained and distributed profits on the same basis. |
CFC: a control test and a tax comparison
The regime can attribute undistributed foreign profit where Icelandic taxpayers collectively own at least 50% or have the relevant control during the year. Control is not limited to the percentage held by one individual. The low-tax test compares foreign tax with two-thirds of the Icelandic tax on a comparable entity and base.
| Issue | What it means | Action |
|---|---|---|
| Control | Direct and indirect interests; Icelandic owners considered together. | Review shareholder agreements and management influence. |
| Low taxation | Less than two-thirds of the comparable Icelandic tax. | The foreign headline rate alone is insufficient. |
| EEA / EFTA / Faroe Islands | Genuine economic activity plus information conditions. | Retain substance and access-to-information evidence. |
| Other jurisdictions | Information access and predominantly non-property/passive income conditions. | An existing treaty alone does not complete the exception. |
| Calculation | Attributed profit is adjusted for Icelandic tax rules. | Reconcile earlier inclusions with later distributions and losses. |
Withholding: distinguish companies from individuals
These are domestic starting rates for payments to nonresident companies, not treaty rates or the final tax on a resident owner. Skatturinn requires approval of a treaty exemption or reduction before the payer uses it; otherwise domestic withholding and a later refund procedure may apply.
| Outbound payment to a nonresident company | Domestic starting rate | Qualification |
|---|---|---|
| Dividends | 20% | Recipient residence, legal form and treaty entitlement matter. Qualifying EEA company recovery can require assessment and a return. |
| Interest | 12% | Specific statutory exemptions and treaties must be tested for the instrument and recipient. |
| Royalties and covered rights / rentals | 22% | First determine whether the payment is within Article 3(6); service fees are not automatically royalties. |
VAT is a turnover and supply-chain question
The standard rate is 24%; specified supplies qualify for 11%. The ordinary small-business registration threshold is ISK 2 million of relevant turnover over any twelve-month period, not profit or a tax-year allowance. Exempt activity, reduced rates and zero-rated supplies are different categories.
| Issue | What it means | Action |
|---|---|---|
| Domestic taxable sales | Monitor the rolling turnover and registration obligation. | Register and invoice correctly when required. |
| Mixed activity | Taxable and exempt operations can coexist. | Allocate costs and input-tax recovery using the applicable rules. |
| Foreign customers or suppliers | Place of supply, import and reverse-charge questions may arise. | Map goods, services, customer status and customer location. |
| Below the threshold | Voluntary registration has consequences. | Do not add VAT to invoices while treating yourself as unregistered. |
Budget for the employer’s side of payroll
General 2026 payroll charges are 6.35% on the defined wage base, which includes employer pension contributions and taxable benefits. Pension contributions are additional. A fishing crew, a financial business, a posted worker and an ordinary office employee can require different treatment. A foreign company hiring locally also needs this review.
Changing the structure needs transaction-level work
Related-party pricing, financial arrangements and transfers of business assets require a separate analysis under the Income Tax Act. Corporate transfers out of Iceland and cross-border mergers have conditions governing recognition, valuation and any payment relief. They are not the same event as an individual changing address.
Before implementing, build a transaction schedule: which entity owns each asset; what moves; the legal consideration; the tax value and market value; who signs contracts; where the people will work; and which country keeps taxing rights. This guide does not supply a universal exit-tax instalment or interest-deduction result.
