Plan contractor hiring in Finland

For a genuine independent engagement, the foreign buyer pays nonwage compensation and the Finland-resident provider owns Finnish tax and entrepreneur insurance. A nonresident buyer without a Finnish permanent establishment does not report that fee to the Incomes Register. The contractor should test YEL separately: it becomes compulsory within six months when self-employment lasts at least four months, annual YEL income reaches EUR 9,423.09 in 2026, and the person is at least 18; the obligation ends at age 68 for those born in 1957 or earlier, age 69 for those born from 1958 to 1961, and age 70 for those born in 1962 or later. YEL income reflects the work input's value, rather than the invoiced amount. The operating split depends first on genuine contractor status and then on the provider completing the registrations and filings tied to it.

If the line is crossed

If the relationship is employment, the fee becomes wages and the foreign company assumes employer duties even without a Finnish entity or permanent establishment. Finnish wage reporting can apply because the employee works and is insured in Finland or stays there for more than six months. A no-PE foreign employer need not enter the Employer Register or withhold Finnish tax unless it registers voluntarily; a resident employee staying beyond six months generally pays Finnish income-tax prepayments personally. Social insurance is separate: a foreign employer with a full-time remote employee in Finland must arrange Finnish statutory coverage, fund the contributions and report earnings, unless a valid foreign-coverage exception applies. The parties should therefore redesign the tax, reporting and insurance workflow before continuing the engagement as employment.

For an ordinary B2B service, Finland places the supply in the business customer's country. The Finland-resident seller therefore issues the foreign business an invoice without Finnish VAT, and the customer accounts for VAT under reverse charge in its country. Before using that result, confirm that the customer acts as a business and that the service is within the general rule; property-related services, passenger transport, event admission, restaurant services and other exceptions can move the place of supply. The Finland-specific hinge appears when the customer is in another EU Member State: even a business below the ordinary small-business threshold may have to register for Notification of VAT on EU Service Supply and submit VAT returns and EU Recapitulative Statements for reportable periods.

What an invoice has to show

• The seller's Y-tunnus and, for an EU service report, FI VAT number

  A Finnish business entered in the Trade, VAT, prepayment or Employer Register places its Business ID on the invoice. For an EU reverse-charge service, use the seller's Finnish VAT identification number as well: FI followed by the Business ID with the hyphen removed. This lets the EU customer connect the invoice with the supplier VAT identity used in recapitulative reporting. Keep the two formats distinct during onboarding because a Business ID alone does not establish that the seller holds the VAT-related registration needed for an EU service sale; confirm that status separately in YTJ.

• Reverse charge

  When the foreign business customer accounts for VAT, the invoice must include the phrase reverse charge. It must also omit both the VAT rate and the amount of VAT payable. Finnish guidance applies that marking to general-rule services supplied to an EU business and to a business outside the EU where the purchaser is liable. A fuller EU reference such as Reverse charge, Art. 44, VAT Directive may be used, yet the required Finnish invoice signal is the reverse-charge phrase. First confirm that no special place-of-supply rule moves the service back to Finland or another location.

• The customer's EU VAT number for an EU reverse-charge sale

  For a customer established in another EU Member State, show the customer's VAT identification number from that state because the customer is liable under reverse charge. Validate it before invoicing and retain the result as evidence that the customer acts as a business. For a customer outside the EU, the same EU-number requirement does not apply. Finnish guidance instead accepts suitable proof of business status, such as an authority certificate, a trade-register extract or a comparable tax number. That distinction matters because the buyer-country rule depends on the recipient being a business and using the service in that capacity.

For an EU general-rule service, issue the invoice by the fifteenth day of the calendar month after the supply month, while the payment due date comes from the contract and its governing law. Finland prescribes no additional VAT invoice deadline for a service supplied to a business outside the EU, so the contract should set that billing cadence. Keep invoice timing separate from the due date: the VAT rule determines when the invoice is issued, while the contract and its governing law determine when the debt matures. State the due date or payment period clearly, together with the agreed invoice currency, so both parties can identify the start of any late-interest period without reconstructing the commercial agreement.

When invoices are settled

Where Finnish law governs, a B2B payment period longer than 30 days requires express agreement; late interest starts on a binding due date or, without one, after 30 days from sending the invoice or demand once received. The parties may choose the law; in an EU forum applying Rome I, a services contract without a choice ordinarily follows the service provider's habitual residence, subject to exceptions, which can point this Finland-resident engagement to Finnish law. The 30-day rule permits a clearly agreed longer period and does not impose a universal 30-day due date. The commercial rate is Finland's statutory reference rate plus eight percentage points.

The currency on the invoice

The contract can select euros or another currency for the service fee. Finnish invoice rules specifically require any Finnish VAT payable on a foreign-currency invoice to be shown in euros. A correctly treated general-rule cross-border B2B invoice carries no Finnish VAT amount, so that conversion requirement has no figure to operate on here. The buyer and contractor should still write the chosen currency into the contract, invoice and due-date clause consistently, and allocate any exchange-rate exposure in the commercial terms. Recheck the currency presentation if a special place-of-supply rule makes Finnish VAT chargeable, because the euro VAT display then becomes relevant even when the fee is denominated elsewhere.

Treating a Y-tunnus, prepayment entry or invoicing service as a status decision

These items are useful onboarding signals, yet none answers Finland's employment question. A Business ID only identifies the business and does not even establish its register entries. The Tax Administration says prepayment registration expresses no conclusion about the payer-provider relationship, and the occupational-safety authority gives the same warning for invoicing services. Review the agreement and actual work against the statutory characteristics: personal service, remuneration, and the buyer's rights of direction and supervision. Record practical facts such as working-time control, assignment plurality, financial risk and responsibility for the result. If the arrangement changes, repeat the analysis instead of relying on the original vendor record.

Stopping the VAT check at EUR 20,000

The ordinary small-business test asks whether qualifying turnover stays within EUR 20,000 in both the current and preceding calendar years. That calculation is only one decision. When the customer is in another EU Member State and receives a general-rule service, the contractor can still need Notification of VAT on EU Service Supply below the threshold. The registration leads to VAT returns and EU Recapitulative Statements for reportable periods, even though the customer remains liable under reverse charge and the invoice contains no Finnish VAT. Ask where the customer is established and which place-of-supply rule applies before concluding that low turnover removes Finnish VAT administration.

Adding Finnish VAT to a general-rule foreign-business invoice

An ordinary B2B service supplied by the Finnish contractor is located in the business customer's country. The invoice therefore excludes Finnish VAT, states reverse charge, and omits a VAT rate and VAT-payable amount. An EU customer's VAT number also belongs on the invoice. Before applying that treatment, confirm business status and screen the service against the specific exceptions for property, transport, events, restaurant services and other specially located supplies. Adding Finnish VAT without that analysis gives the customer the wrong document and can conflict with the seller's cross-border VAT reporting. For an EU customer, also complete the separate EU-service registration and reporting workflow where required.
