Address registration in Iceland is mandatory for anyone staying longer than six months. This guide explains how to register your legal domicile with Registers Iceland, what documents you need, and what your registered address affects.
Helping you navigate your move and settling in the land of fire and ice.
Iceland offers low corporate tax rates and a straightforward registration process for foreign entrepreneurs. This article covers business structures, registration steps, costs, and tax obligations for starting a business in Iceland.
Taxes in Iceland are progressive, with three income brackets ranging from 31.49% to 46.29% (as of 2026). A personal tax credit makes the first portion of income tax-free, and your employer handles all withholding.
A week-by-week checklist covering everything you need to do in your first 30 days in Iceland, including kennitala registration, banking, housing, and settling in.
Anyone staying in Iceland beyond a few months is required by law to register a legal address. The Icelandic term is lögheimili (legal domicile), and it is more than a bureaucratic formality. Your registered address determines which municipality collects your local income tax, whether you qualify for public healthcare, and which social services you can access. Without a registered address, you are effectively invisible to the Icelandic system.
This article covers who must register, how the process works, what documents you need, and what happens if you move within Iceland after your initial registration. For the full picture of settling in, see our complete relocation guide.

If you plan to stay in Iceland for more than six months, you must register a legal address with Þjóðskrá Íslands (Registers Iceland). This applies regardless of nationality. The requirement kicks in at different points depending on where you are from.
EEA/EFTA citizens must register with Registers Iceland if they stay longer than three months. If you are actively seeking employment, you have up to six months before registration is required. Registration covers both your kennitala (national ID number) and your legal address in a single process. You do not need a separate residence permit.
Non-EEA/EFTA citizens must hold a valid residence permit before they can register an address. The permit is issued by the Directorate of Immigration. Once you have it, you register your address with Registers Iceland.
Nordic citizens (from Denmark, Finland, Norway, or Sweden) follow a simplified process. If staying longer than six months, they register directly with Registers Iceland. No residence permit is needed.
In all cases, you need a kennitala before or as part of the registration. If you do not yet have one, see our guide to the kennitala.
Not every place you sleep qualifies as a legal address. Icelandic law requires that your registered address be a permanent residential property with a named street address or a named building.
The following do not qualify: guesthouses, hotels, hospitals, construction camps, worker dormitories, and fishery accommodation. If you are staying in temporary housing while apartment-hunting, you cannot register that address as your legal domicile.
In practice, this means you need a signed rental agreement or proof of property ownership at a specific address before you can complete registration. If you are still looking for a place, our rental apartment guide covers where and how to search.
Your first address registration in Iceland happens as part of the broader process of registering with Registers Iceland and obtaining your kennitala. For most newcomers, this is done in person.
The main option is to visit Registers Iceland in person at Borgartun 21, Reykjavik. The office is open Monday to Friday, 10:00 to 15:00. Bring your passport, proof of address (rental contract or property deed), and any residence permit documentation if applicable.
EEA/EFTA citizens apply for registration using the process outlined on the Registers Iceland EEA/EFTA page. Depending on your situation (employed, self-employed, student, or self-sufficient), you will need different supporting documents.
Non-EEA/EFTA citizens should already have a residence permit before visiting Registers Iceland. The immigration process through island.is handles the permit; address registration follows once the permit is granted.
Once registered, you will receive confirmation by email. Most registrations are processed within a few days, though some cases take longer.
The exact documents depend on your nationality and situation, but the core requirements are consistent.
Document | Who needs it |
|---|---|
Valid passport or national ID | Everyone |
Proof of address (rental contract or property deed) | Everyone |
Residence permit | Non-EEA/EFTA citizens |
Employment contract or proof of enrollment | EEA/EFTA citizens (varies by category) |
Health insurance documentation | Self-sufficient EEA/EFTA citizens |
Marriage certificate (if registering with a spouse) | If applicable |
EEA/EFTA citizens registering as employees need an employment contract. Students need proof of enrollment at an Icelandic educational institution. Self-sufficient individuals must show proof of health insurance and sufficient funds.
For the most current document requirements, check the Registers Iceland moving to Iceland page.
Once you are registered in Iceland and have a kennitala, changing your address is straightforward. You must report any change of address within seven days of moving.
The fastest option is online. Log in to island.is using your Icelandic electronic ID. The form takes a few minutes. Once submitted, your new municipality and other government agencies are updated automatically.
You can also visit Registers Iceland at Borgartun 21, Reykjavik, with a valid ID. The office is open Monday to Friday, 10:00 to 15:00.
People aged 18 and older must submit their own change of address. You cannot do it on behalf of another adult (with limited exceptions for care facilities).
After changing your address, remember to also notify Iceland Post separately. The postal service does not automatically update when you change your registration with Registers Iceland.
Your registered address in Iceland is not just a record of where you live. It is the foundation for several critical systems.
Iceland's municipal tax (útsvar) varies by municipality. When you register your address in a particular town, that municipality collects your local income tax. Rates range from 12.44% to 14.94% (as of March 2026), so where you register has a direct financial impact. For more on how Icelandic taxes work, see our tax system guide.
Registration at a legal address is a prerequisite for enrollment in Iceland's public health insurance system through Icelandic Health Insurance (Sjúkratryggingar Íslands). Without it, you are not covered. See our health insurance guide for the full enrollment process.
Access to municipal social services (childcare subsidies, housing assistance, elder care, disability support) depends on being registered in that municipality.
Foreign nationals who have been legally domiciled in Iceland for more than three consecutive years gain the right to vote in municipal elections. Nordic citizens are eligible to vote in municipal elections without any waiting period beyond having a registered legal domicile. Your registered address determines your voting district.
Children are assigned to schools based on their registered address. If you have children, see our schools in Iceland guide.
Iceland distinguishes between legal domicile (lögheimili) and temporary residence (dvalarstaður). They are not the same.
Legal domicile is your permanent registered address. It is where you officially live, and it governs your tax obligations, healthcare eligibility, and municipal services.
Temporary residence is a secondary registration for people who need to live away from their legal domicile for a specific reason. The two recognized reasons are studies and illness. A university student from Akureyri studying in Reykjavik, for example, might keep their legal domicile in Akureyri while registering a temporary residence in Reykjavik.
Temporary residence registration requires supporting documentation: proof of enrollment for students or a doctor's certificate for those relocating due to illness. It is handled through Registers Iceland.
One exception: under the Nordic Agreement, Nordic citizens studying in another Nordic country cannot register a temporary residence in Iceland.
If one spouse moves to a different address, the other spouse must confirm the change. The non-moving spouse has 48 hours to submit form A-253 through Registers Iceland. If the confirmation is not received within 48 hours, the address change is rejected and a new notification must be submitted.
Married couples are allowed to be registered at different legal addresses. The confirmation requirement exists to prevent fraudulent address changes, not to block separate registrations.
Unmarried cohabitants and registered partners each submit their own change of address independently. The 48-hour confirmation rule does not apply to them.
You must register your legal address within your first six months in Iceland. In practice, registration happens alongside your kennitala application, which most people complete within their first few weeks. Once registered, any subsequent address change must be reported within seven days.
Your initial registration when first moving to Iceland is done in person at Registers Iceland (Borgartun 21, Reykjavik). After that, address changes can be done online through island.is using an Icelandic electronic ID.
Residing in Iceland for more than six months without a registered legal address is illegal. More practically, you lose access to public healthcare, municipal social services, and you are not registered in the national social security system. Your employer also cannot properly process your tax withholdings without a registered address.
Icelandic law does not require landlord approval for address registration. You register your own address based on where you actually live. That said, your rental contract serves as proof of address during the registration process.
Registering your address and submitting change-of-address notifications are free. However, if you need a formal confirmation of your legal domicile as a certificate (for visa applications, legal proceedings, or similar purposes), Registers Iceland charges a fee for that document.
If you previously lived in Iceland and deregistered, you must re-register your legal address within three months of returning. The process uses form A-271 through Registers Iceland. You will need the same documentation as a new registration (passport, proof of address, and any applicable permits).
