Norwegian VAT (mva) on Wix Stores and how it maps to Fiken VAT codes
By Kayabyte
Disclosure: Kayabyte makes Sales Bookkeeping Sync, an app for Wix sites that this guide describes in one section. Norwegian VAT rates are as published by Skatteetaten (the Norwegian Tax Administration, skatteetaten.no); check the current rates there, as this guide is not tax advice, so check unusual goods with your accountant. Checked on 11 November 2026.
The short answer: Norway’s VAT (merverdiavgift, mva) has a general rate of 25 percent, 15 percent on food, 12 percent on things like passenger transport, hotel stays and cinema tickets, and 0 percent (exempt) on goods such as books. In Wix Stores you set these as tax groups; in Fiken each one is a VAT code that must fit the sales account. Map them rate by rate: 25 to the high rate, 15 to medium, 12 to low and 0 to exempt.
Step 1: set up Norwegian tax in Wix Stores
In your Wix dashboard open Settings > Taxes for Wix Stores. Choose Norway, set the general rate to 25 percent, and decide whether your prices include VAT. Norwegian consumers expect prices with VAT included, so most Norwegian shops choose “tax is already included in my prices”. Create extra tax groups for products with another rate, for example “Food 15%”, “Transport, cinema, hotel 12%” and “Exempt 0%”, and put each product in the right group. Check that shipping is taxed at the rate that applies to it (normally 25 percent).
Step 2: the Fiken side
Fiken books a sale line with an account and a VAT code, and checks that they belong together. The usual pairs:
| Rate on the Wix order | Fiken VAT code | Typical sales account |
|---|---|---|
| 25% | High rate (HIGH) | 3000 Sales of goods, high VAT rate |
| 15% | Medium rate (MEDIUM) | account for sales with the medium rate (food) |
| 12% | Low rate (LOW) | account for sales with the low rate |
| 0% | Exempt (EXEMPT) | account for VAT-exempt sales |
Which exact account numbers your company uses depends on its chart of accounts. If a pair does not fit, Fiken refuses the sale with a message such as “SALG_MED_MIDDELS_SATS is not a valid VAT code for account 3000. Possible codes are [SALG_MED_HØY_SATS]” (in Norwegian in Fiken). That is a mapping problem, not a bug: use a different sales account for that rate.
Step 3: map the rates in Sales Bookkeeping Sync
Sales Bookkeeping Sync (app page) reads the VAT rates that appear on your orders and lists each one in Settings > VAT. Each rate gets a Fiken VAT code, and the app suggests the code with the same percentage. The sales account is chosen once in Settings, and Fiken only accepts the VAT codes that belong to that account. Check the first sale of each rate in Fiken: if Fiken refuses a pair, its message appears on the order in the Sync log.
The app sends the net amount and the VAT amount of each line exactly as Wix calculated them, with no rounding of its own, so totals in Fiken equal totals in Wix. Fiken does not recompute the VAT; this is why checking the first orders matters.
Tax-inclusive and tax-exclusive prices
With tax-inclusive prices, Wix shows the gross price and the VAT inside it; the app subtracts the VAT to get the net amount for Fiken. With tax-exclusive prices the line price is the net amount. Both work. Discounts, shipping and extra fees are separate lines with their own VAT.
Exports and foreign currency
Fiken accepts a sale in a foreign currency only without Norwegian VAT, such as an export. A Wix order in euros with 25 percent VAT cannot be booked by Fiken’s API, so the app marks it as needing attention with that explanation. Prices in NOK with Norwegian VAT are the normal case.
Checklist
- Wix tax groups for each rate you use, products assigned.
- A Fiken sales account for each rate, with a VAT code that fits.
- Rates mapped in Settings and saved.
- One test order per rate, then compare total, VAT and income in Fiken.
The whole setup is in How to connect Wix Stores to Fiken.

FAQ
What are the Norwegian VAT rates for a web shop? 25 percent general, 15 percent food, 12 percent for passenger transport, accommodation and cinema, and 0 percent for exempt goods such as books. See Skatteetaten for the current rules.
Which Fiken VAT code is 25 percent? The high rate. 15 percent is the medium rate and 12 percent the low rate.
Why does Fiken refuse my sale with a VAT code message? The VAT code does not belong to the sales account you chose. Pick the account that Fiken lists for that code.
Does the app calculate VAT? No. It copies Wix’s net and VAT amounts line by line, so Wix stays the source of the numbers.
Do I need to register for VAT to use this? Whether you must register depends on your turnover and Norwegian rules; ask your accountant. The app works with the VAT setting your Fiken company has.
