Revolut draws tax scrutiny in Finland, HS finds grey-economy links above 10 percent, regulators chase neobank growth

• HS reports that a Tax Administration review found grey-economy links among more than one in ten of Revolut’s Finnish customers.
• The case puts attention on neobanks’ role in tax enforcement, account reporting and cross-border money flows.
• Grey economy in Finland covers undeclared income, concealed business activity and other efforts to avoid taxes or statutory payments.
• The pressure falls on regulators to match the speed of digital banking growth with supervision and data access.

More than 10 percent of Revolut’s Finnish customers are linked to the grey economy, according to Helsingin Sanomat, which reports on a Finnish Tax Administration review of neobanks. The figure concerns Finland’s customers of Europe’s largest app-based bank and gives tax authorities a hard number for a market that has grown much faster than the domestic banking habits built around Finnish lenders.

In Finland, the grey economy usually means income, sales or business activity kept outside the tax system, along with unpaid value-added tax, payroll charges or pension contributions. That can include undeclared side businesses, wages paid off the books, accounts used to move money beyond ordinary reporting channels, or fragmented payment flows that make the real scale of activity harder to see. A digital-only bank does not create that behaviour, but it can change the cost of running it: opening an account is quick, transfers are cross-border by default, and the customer relationship sits inside an app rather than a branch office that knows the local business owner by name. For the Tax Administration, the old advantage of domestic banking was not romance but visibility. Salaries, invoices, card payments and tax debts moved through institutions already woven into Finnish reporting systems and compliance routines.

Neobanks alter that balance. Revolut and similar firms offer low-friction accounts, cards, currency exchange and transfers from a phone screen, often under licences and reporting structures built elsewhere in Europe. That is legal and common inside the EU single market, but it shifts practical oversight. Finnish authorities still need data, account information and transaction trails; the difference is that the money may no longer sit first in a Finnish bank under a Finnish compliance department. If customer growth outruns the state’s ability to identify which accounts belong to wage earners, sole traders, shell companies or repeat tax debtors, enforcement gets slower while the payment rails get faster.

HS reports that the Tax Administration has been studying neobanks precisely because they are becoming large enough to matter. Revolut is no niche product for frequent travellers anymore. Once a bank reaches mass-market scale, even a minority of problematic users turns into a substantial enforcement workload, and the burden lands on the tax authority, not on the convenience promised in the app store. Domestic banks, for their part, operate under the same anti-money-laundering and reporting obligations but have longer-established ties with Finnish authorities and more experience handling local tax, debt collection and corporate-account scrutiny. The competitive edge of neobanks is speed and low friction; the state’s problem begins when the same qualities also reduce friction for undeclared trade.

The Finnish question is not whether app banking will keep growing. It already has. The narrower question is whether tax collection and financial oversight can still see enough of the traffic when a growing share of it starts in a foreign-regulated phone app instead of a Finnish bank account. The review cited by HS suggests the answer is expensive to obtain, and late.

The number that triggered the review was plain enough: more than one in ten of Revolut’s Finnish customers had a link to the grey economy.
