Fake Tax Office Scams in Finland
Fraudsters impersonate Verohallinto (the Finnish Tax Administration) by text, email, and phone, demanding payments or harvesting bank credentials through fake refund notices.
Part of: Fake Tax Office Scams
Last reviewed: 1 June 2026
Fake tax-office scams exploit the trust Finns place in Verohallinto and the predictable rhythm of the Finnish tax year. Around the spring tax-return and autumn back-tax periods, fraudsters flood inboxes and phones with messages claiming an outstanding payment, a pending refund, or a problem with the victim's tax card.
The messages are increasingly polished, written in fluent Finnish and Swedish, and often spoof official-looking sender names and the OmaVero branding. The goal is either an immediate payment or, more often, the theft of online-banking credentials via a cloned login page.
How this scam works on Finland
A typical attack arrives as an SMS or email stating that the recipient is due a tax refund and must 'confirm bank details' through a link, or conversely that a back-tax payment is overdue and enforcement is imminent. The link leads to a convincing replica of the OmaVero portal or a Finnish bank's login screen.
When the victim enters their online-banking credentials and a TUPAS or mobile-ID confirmation, the criminals use those details in real time to authorise transfers from the victim's account. Phone variants involve a caller posing as a Verohallinto officer who reads out a genuine-looking reference number and pressures the victim to act before a 'deadline today'.
Finnish-language fluency and references to real concepts like the tax card (verokortti) and prepayment (ennakkovero) make these scams difficult to distinguish from genuine communications.
Common red flags
- An SMS or email with a link asking you to 'confirm bank details' to receive a tax refund
- Threats of immediate enforcement or debt collection unless you pay within hours
- A login page that asks for full banking credentials plus a mobile-ID confirmation
- Sender address or SMS shortcode that does not match official Verohallinto channels
- Requests to pay tax via gift cards, crypto, or a personal account number
- Pressure and urgency rather than the calm, deadline-based tone of real tax letters
- Refund amounts or reference numbers that do not match anything in your own OmaVero account
How to protect yourself
- Never click links in tax messages — log in to OmaVero directly by typing the address yourself
- Remember Verohallinto issues refunds automatically to your registered account, never via a link
- Verify any claimed debt by calling Verohallinto using the number on its official website
- Never enter banking credentials on a page reached through an email or SMS link
- Enable transaction alerts with your Finnish bank so unexpected transfers are caught quickly
- Report suspicious messages and delete them rather than replying
How to report it
- Report tax-impersonation messages to Verohallinto via its phishing-reporting channel on vero.fi
- File a police report at poliisi.fi if you lost money or disclosed banking credentials
- Notify your bank immediately to freeze the account and attempt to recall any transfers
Frequently asked questions
I already entered my banking details on a fake OmaVero page — what should I do immediately?
Contact your Finnish bank right away to freeze the account and change your online banking password and mobile-ID or TUPAS confirmation app. Report the phishing page to Verohallinto and the police, then monitor your account closely for unauthorised transfers over the following weeks.
How can I tell a genuine call from Verohallinto from a scam one?
Genuine tax officials never pressure you to pay immediately over the phone, ask for your full banking credentials, or demand payment via gift cards or crypto. If a caller does any of this, hang up and call Verohallinto back using the number on its official website, not one the caller gives you.
Why do these fake Verohallinto messages look so convincing?
Scammers use real terminology like verokortti and ennakkovero, realistic reference-number formats, and fluent Finnish to mimic genuine correspondence. The safest habit is never clicking a link in an unsolicited tax message — type the OmaVero address yourself or use a saved bookmark instead.
Does Verohallinto ever send links to claim a refund?
No. The Finnish Tax Administration pays refunds automatically into your registered bank account and asks you to manage details through the OmaVero portal that you log into yourself. Any message with a link to 'claim' or 'confirm' a refund should be treated as a scam.
