Requirements for Norwegian Invoices

Navigating the requirements for invoices in Norway

Invoices play an important role in business transactions, acting as a critical record of sales. Invoices detail the goods or services provided, their costs, relevant taxes and the parties involved in the transactions and the terms of payment.  


Turning our attention to Norway, the importance of invoices is especially highlighted. Norway enforces strict invoicing regulations that businesses must comply with, highlighting the country´s commitment to precise billing practices. Like in all other countries, invoices do more than just document transactions; they are tools of efficiency, ensuring a smooth flow of transactions and contributing significantly to the sustainable growth of businesses.

Norwegian Invoice

Sending an invoice can be done both quick and easy. However, there are some easy but important requirements to invoices and how it should be sent. If you are registered in the Norwegian VAT register you have to make sure you are compliant with the requirements applicable.  


Norwegian invoices have some specific requirements that distinguish them from invoices in other countries, primarily because of Norway´s tax regulations and business practises. These requirements ensure compliance with Norwegian accounting and tax laws and that all transactions are properly documented for tax and accounting purposes.  

Key invoice requirements in Norway

Let’s have a look at the key requirements for creating a compliant invoice in Norway  

Each invoice must have a unique number that follows in a sequential order.  

The date when the invoice is issued.

Complete name and address of the seller, as well as the organization number (VAT number if registered in “Merverdiavgiftsregisteret). 

Complete name and address of the buyer. For sales where VAT is charged, the buyers VAT number is required if the buyer is VAT registered.  

A clear description of the goods or services provided.  

The volume or quantity of the goods or services, including the unit price and the nature of the goods or services sold.  

The date and place for when and where the goods have been delivered, or the services have been completed.

Terms of payment including the due date for payment.

The total amount to be paid by the buyer, including the breakdown of net amount, VAT and other applicable charges.  

The VAT rate applied, and the total amount of VAT charged on the invoice. The VAT amount should be mentioned in VAT. Norway typically requires VAT to be specified separately on the invoice If the same invoice includes several VAT rates, you must specify this on separate lines. 

Invoices should be made in an accounting system, and invoices should not be created in for example Word or Excel.  

You can invoice in other currencies, like Euro, but you should add the VAT amount in NOK. It is recommended to state the used currency rate on the invoice. The currency rate to be used is the official on the time of invoicing. But if you are using an accounting system, it should take care of that automatically. 

What separates a Norwegian invoice from others?

Here are some key aspects that might typically separate Norwegian invoices from others:

Norwegian organization number

Norwegian invoices must include the seller´s Norwegian organization number (Organisasjonsnummer). This is a unique nine-digit identifier for every registered entity in Norway. If VAT registered in Norway, your Norwegian VAT number should be mentioned: the VAT number is your Norwegian organization number followed with “MVA”.  You are allowed to prefix with “NO”.  

Norwegian VAT rates

Norway has specific VAT rates that must be applied correctly and displayed on the invoice. You can learn more about Norwegian VAT here. 

Use of Norwegian currency (NOK)

While not exclusive to Norway, invoices typically list amounts in Norwegian Kroner (NOK). The invoice may show another currency, but VAT must be calculated and shown in NOK, often alongside the original currency. The currency rate to be used is the official one at the moment of invoicing. 

Reverse charge VAT mechanism

For services supplied to Norwegian businesses from abroad, the invoice may need to indicate that the reverse charge mechanism applies, meaning the recipient of the service (if VAT registered in Norway) is responsible for reporting and paying the VAT.  

Electronic invoice format

Norway encourages the use of electronic trading format invoices, especially for transactions with the public sector. The format is designed to streamline the invoicing process, ensuring compatibility and efficiency in electronic invoice exchanges. Most commonly used is EHF, based on the European standard (UBL, CEN, Peppol BIS). 

Language preferences

While not a strict requirement, invoices in Norway are commonly issued in Norwegian, especially for domestic transactions. English is widely accepted, particularly for international business, but including a Norwegian version or summary can be beneficial for clarity and compliance.  

Detailed VAT breakdown

Norwegian law requires a detailed breakdown of VAT on the invoice, showing the VAT rate applied, the base amount the VAT is calculated from, and the total VAT amount in NOK. This is essential for both domestic and international transactions involving Norwegian entities and foreign entities registered in the Norwegian VAT register
