Do you need VAT registration in Norway as a foreign company?

The problem

Your company sells — or will sell — into Norway, and Norwegian VAT registration is mandatory past a threshold most foreign companies don't know exists. Registering late means the tax authority assesses the VAT afterwards: you rarely manage to re-invoice customers, so the VAT, interest and penalties come out of your margin.

Decision criteria

Four facts decide your obligation: your taxable turnover in Norway over any rolling 12-month window (threshold: NOK 50,000); what you supply (goods, on-site work, remote services); who you supply (businesses or consumers); and whether you have a place of business in Norway (decides direct registration vs VAT representative).

Scenarios

Remote B2B services only. Reverse charge often shifts the VAT duty to your Norwegian customer — registration may not be required. One on-site element or B2C sale pulls you back in. Verify, don't assume.

Construction or on-site work. A single mid-sized invoice usually exceeds NOK 50,000. Treat VAT registration as part of project setup, alongside worker obligations and assignment reporting.

Goods / e-commerce to consumers. Low-value goods (under NOK 3,000 per item) sold directly to Norwegian consumers fall under the VOEC scheme — its own registration, regardless of the 50k logic.

Below threshold. No duty yet. Track Norwegian turnover from the first krone per rolling 12-month window — the threshold arrives faster than expected.

Outcome classification

Your situation	Outcome
Turnover above NOK 50,000	🔴 Registration required now — possibly via VAT representative
Approaching the threshold	🟡 Prepare now (bank, bookkeeping, representative take weeks)
Remote B2B services only	🟡 Reverse charge may apply — professional verification worth 15 minutes
Low-value B2C e-commerce	🟡 Check VOEC regardless of size
Well below threshold, no VOEC	🟢 Not yet — monitor the rolling window

Direct registration or fiscal representative?

Foreign companies without a Norwegian place of business register in one of two ways. Businesses established in EEA states with mutual assistance agreements with Norway — including Spain and Portugal — can generally register directly. Companies from other countries must appoint a Norwegian VAT representative. Either way, the bi-monthly returns run in Norwegian systems and the bookkeeping must meet Norwegian standards, which is why most foreign companies hand the chain to a Norwegian accountant regardless of route.

Timing — the mistake that costs the margin

Registration is not something to do "once the project is running". The obligation crystallises when taxable turnover passes NOK 50,000 in any rolling 12-month window — in B2B construction or installation work, that is usually the first invoice. The invoice that crosses the threshold should already carry VAT. Register in parallel with contract signing, not after mobilisation.

Frequently asked questions

Does the NOK 50,000 threshold reset each calendar year? No — it is a rolling 12-month window, not a calendar-year figure. Track cumulative Norwegian taxable turnover from your first invoice.

We only sell B2B services remotely — do we still register? Remote B2B services are often covered by reverse charge, where your Norwegian customer accounts for the VAT. But on-site work, construction and goods rarely escape registration. Classify before you assume.

Can we recover Norwegian VAT on costs before registration? In some cases, yes — input VAT on pre-registration costs can be recovered retrospectively once registered, if documentation is in order. Keep every Norwegian cost invoice from day one.

How long does VAT registration take? The VAT registration itself is usually quick once the company has a Norwegian organisation number — the entity registration (typically a NUF) is the step that takes weeks. Sequence: entity first, VAT second, first invoice third.

What if we already invoiced without VAT? Skatteetaten assesses the VAT afterwards, and re-invoicing customers months later rarely works — the 25% comes out of your margin, plus interest. The sooner it is corrected voluntarily, the cheaper it ends.
