You can order a new tax card for 2017 online from the Finnish Tax Administration until December 12th 2017. After that you can order one by either calling or visiting your local Tax Office.
New tax cards for the year 2018 will be put to use February 2nd 2018.
Unless you haven't provided us with a new tax card "muutosverokortti", we will automatically use your new one starting from February 1st 2018.
From January 2021, we will receive your tax information directly from the Finnish Tax Administration. This means that your income limits and tax percentages listed in the Tax Administration's omavero.fi service will be automatically transferred to our system based on your identification and payroll calculation. This will not require you to take any action via the UKKO.fi service, and you no longer need to provide us with your tax card separately.
It is possible that we will be unable to retrieve your tax information. If this is the case, you must submit your tax card electronically through our service. Instructions on doing this can be found here >> How do I submit my tax card?
