Getting a Tax Card and How Income Tax Works in Iceland: A Guide for Foreign Workers
If you are moving to Iceland for work, one of the first things you will hear about is the tax card, or skattkort in Icelandic. It sounds complicated, but the good news is that the system is largely automatic and your employer takes care of most of the hard parts for you. This guide explains in plain English what a tax card is, how the personal tax credit reduces the tax taken from your pay, and what to do if you have more than one job. It is meant as a friendly orientation, not official tax advice, so always confirm the current rates and rules with Iceland Revenue and Customs (Skatturinn). Once you understand the basics, you will feel much more confident reading your first Icelandic payslip.
What a tax card (skattkort) actually is
A tax card, called a skattkort in Icelandic, is the official record that tells your employer how to handle the income tax taken from your wages. In the past it was a physical paper card that you handed to your boss, but today it is fully electronic and lives in the systems of Iceland Revenue and Customs (Skatturinn). This means there is usually no card for you to carry around or hand over by hand. When you start a job, your employer can access your electronic tax card and apply it to your pay automatically through the payroll system. So while the name might make you picture a plastic card, in practice it is simply a digital entitlement linked to you. Knowing this saves a lot of confusion when a new colleague asks where your tax card is and you realise there is nothing physical to find.
You need a kennitala first
Before any of this can work, you need a kennitala, which is the Icelandic national identification number. The kennitala is the key that connects you to the tax system, the health system, your bank, and almost everything else official in Iceland. Your electronic tax card is tied to this number, so without a kennitala there is nothing for your employer to look up. This is why sorting out your kennitala early is so important when you arrive, and it is usually one of the very first steps for any newcomer. Once you have your kennitala registered, your tax card effectively comes into being in the background. If you are still in the process of getting your number, it is worth treating that as the priority, because the rest of the tax setup follows naturally from it.
The personal tax credit (persónuafsláttur)
One of the most important ideas to understand is the personal tax credit, known in Icelandic as persónuafsláttur. This is an amount that everyone working in Iceland is entitled to, and it reduces the income tax that is withheld from your salary each month. You do not have to do anything clever to claim it; when your employer uses your electronic tax card, the credit is normally applied to your pay automatically. A helpful feature is that any part of the credit you do not use in one month can carry over to later months in the same year, so it is not simply lost. In addition, if you are married or in a registered partnership, unused personal tax credit can often be transferred between spouses, which can help couples make the most of it. The exact amount of the credit changes over time, so rather than relying on a figure here, check the current value directly with Iceland Revenue and Customs (Skatturinn).
What happens if your employer has no tax card for you
If your employer cannot access a valid tax card for you, they are required to withhold tax from your pay at a higher rate, often without applying your personal tax credit. This can come as a shock when you see your first payslip and notice that much more has been deducted than you expected. The reason is simply that, without your tax card and credit in the system, the employer has to play it safe and take the maximum. The good news is that this situation is almost always temporary and fixable once your kennitala and tax card are properly in place. This is exactly why it pays to sort out your registration as early as you can, ideally before or right at the start of your first job. Getting it done quickly means more of your hard-earned money stays in your pocket from the beginning.
Using your tax credit at only one job at a time
If you work more than one job in Iceland, there is an important rule to keep in mind about your personal tax credit. The full credit can only be applied at one job at a time, not spread across several employers at once. If you accidentally let two employers both apply your full credit, you may end up underpaying tax during the year and then facing a bill later when everything is reconciled. To avoid this, you decide where your tax credit should be used, usually placing it with your main or highest-paying job. Your secondary employer then withholds tax without that credit, which keeps your overall position correct. If you are unsure how to manage this across multiple jobs, Iceland Revenue and Customs (Skatturinn) can explain how to direct your credit so that you do not get caught out.
Skatturinn, your annual tax return, and checking your payslips
Iceland Revenue and Customs, known as Skatturinn, is the authority that oversees income tax and runs the systems your employer connects to. Each year there is an annual tax return, where your income and the tax you have paid are reviewed, and any small differences are settled, sometimes resulting in a refund and sometimes a balance to pay. The reassuring part is that your employer handles the month-to-month payroll mechanics, calculating and forwarding your tax for you, so you are not expected to do complex sums yourself. Even so, it is a very good habit to check your payslips regularly to make sure your tax card and personal tax credit are being applied correctly. If something looks off, raising it early with your employer or with Skatturinn is much easier than fixing it months later. With your kennitala and tax card sorted and a quick eye on your payslips, the Icelandic tax system becomes far less intimidating than it first appears, so get yourself set up and start applying for the work that brings you here.
