About 1.8 million Finns must verify and correct their pre-filled tax return information by the end of today, the Finnish Tax Administration has reminded, as reported by Yle citing STT.

The tax decision will be issued digitally via the Omavero service for most taxpayers, even if the pre-filled return was originally sent by post.

While the majority of pre-filled tax returns contain correct details, the Tax Administration urges all taxpayers to review their information, correct any errors or omissions, and add eligible deductions or unreported income.
