You need a tax card before your first salary — without it, the employer withholds 60% as tax.
Log in to OmaVero at vero.fi with Finnish bank credentials or Mobile Certificate (requires personal identity code).
Open 'Tax card and tax return estimate' and fill in your estimated annual income, employer, and deductions.
Submit the form — OmaVero calculates your withholding rate and issues a digital tax card. Download it or email it to your employer.
If your income changes significantly during the year, update the tax card in OmaVero — the new rate applies from the next pay period.
