On 31 August 2026, the Icelandic Directorate of Internal Revenue (Skatturinn) disclosed a typographical error in mileage tax (kílómetragjald) invoices distributed to taxpayers via the digital mailbox on Iceland.is over the preceding weekend. The error involved incorrect vehicle registration numbers appearing in the invoice headers, potentially causing confusion for vehicle owners attempting to verify or pay the tax. The mileage tax, introduced under the Act on Mileage Tax, applies to all vehicles registered in Iceland and is calculated based on odometer readings reported annually. The invoices are generated automatically from the vehicle registry database and sent electronically to the owner’s digital mailbox. Skatturinn identified the issue promptly after it was reported by taxpayers and has since corrected the underlying data feed.
Key Takeaways
- Error Identification and Scope: The error affected a batch of invoices sent between 29 and 30 August 2026. The registration numbers displayed in the invoice header did not match the vehicle associated with the taxpayer’s account. However, the underlying tax calculation and vehicle identification in the tax authority’s core systems remained correct. Only the display field in the PDF invoice was affected.
- Correction Process: Skatturinn has regenerated corrected invoices and resent them to the affected taxpayers’ digital mailboxes. The corrected invoices bear a revised issue date and a note indicating the correction. Taxpayers who already paid based on the erroneous invoice should verify that the payment was allocated to the correct vehicle; the authority confirms that payments are matched by the taxpayer’s national ID and the tax type, not by the registration number shown on the PDF.
- Taxpayer Action Required: Recipients of the original erroneous invoices are advised to discard them and use the corrected versions for their records. No additional action is needed if payment has not yet been made. For those who have paid, Skatturinn recommends checking the payment status in the online tax portal to confirm proper allocation. The authority has also set up a dedicated helpline and email address for inquiries related to this issue.
