Iceland tax residency: the 183-day rule
You have unlimited tax liability in Iceland if you have a permanent residence there, or stay there for more than 183 days in total in a 12-month period — normal absence for holidays counts as part of the stay. It runs from the day you arrived. Having moved away, you stay liable for 3 years unless you show you’re taxable in another country.

More than 183 days in Iceland in any 12 months make you resident, from the day you arrived. Normal holidays abroad count as days in Iceland: add them as stays.
Iceland tax residency: more than 183 days
Iceland’s tax administration (Skatturinn) gives you unlimited tax liability — tax on your worldwide income — if:
- you have a permanent residence in Iceland;
- you stay in Iceland for more than 183 days in total in a 12-month period; normal absence for holidays and the like counts as part of the stay, and so does work on an aircraft or ship registered in Iceland; or
- you’ve moved away but haven’t shown you’re taxable in another country.
Liability by the days runs from the day you arrived.

Leaving Iceland
- Three years: former residents stay fully liable for 3 years after leaving, unless they show they’ve become taxable in another country.
- Students abroad can apply to keep their Icelandic tax domicile, and the rights that come with it.
- Who decides: the Director of Internal Revenue rules on who is domiciled in Iceland; the ruling can be appealed to the Internal Revenue Board.
Worked example
You were in Iceland from 23 September to 31 December: 100 days. Staying on from 1 January, you can stay until 24 March — your 183rd day in 12 months. On 25 March you’d be past 183. A holiday abroad in between counts as days in Iceland: add it, and the date comes sooner.
Ireland counts 183 days in the year, or 280 over two: see Ireland tax residency. Other countries, side by side: 183-day rule by country.
How FlySee counts it
FlySee has no Iceland tracker built in; a tax tracker of your own counts the days: Iceland, fewer than 184 days, any 12 months, any part of a day. Any 12 months are counted over 366 days — a day early, never late. Iceland also counts normal holidays abroad as part of the stay: add those days yourself.
