How the counting works
The three-year tail after emigration is the notable feature: giving up Icelandic domicile does not end unlimited liability unless you can show equivalent taxation and compliance in another state. Cited source is the Alþingi (Parliament) publication of the consolidated Act No. 90/2003; Skatturinn's own tax liability page rendered as navigation only. The statute states no part-day convention. Worldwide taxation of those with unlimited liability rests on the same article, which speaks of liability for all income wherever earned; that specific wording was not separately extracted.
Why the day count is the part you can control
Ties, homes and intentions are argued after the fact; days are a record. That is why the first thing an adviser asks for is a list of the days you were in the country — and why reconstructing it from boarding passes and photos a year later is a bad afternoon. Log each stay as it happens and the tally is simply there, with the dates that produced it. If you are moving to Iceland to work remotely, the Iceland digital nomad visa page covers the permission side.
