All persons working in Iceland must register for tax with the Directorate of Internal Revenue (Rikisskattstjori). Tax registration is linked to the Kennitala and produces a tax card (Skattkort) that determines the withholding rate applied to your salary. This guide explains how to register for Icelandic tax after receiving your Kennitala, how to obtain a Skattkort, the standard withholding rates, how to file an annual tax return in Iceland, and the consequences of working without a Skattkort.
