Conta collects the information to be submitted based on what you have recorded in your accounts. Before you start, make sure you have registered all vouchers with the correct VAT code and reconciled your bank account for the period you are reporting.
To set how often you submit the VAT return, go to the top menu > My business > Settings. Here you choose whether your business submits the VAT return annually or six times a year.
Please note! VAT-registered businesses usually submit six VAT returns a year. The exception is businesses that have applied for and been granted annual reporting.
It is important that you choose the option that matches the information your business has received from the authorities, so that the VAT return shows the correct figures.
In the same place, you can also choose which type of VAT report you submit. The general VAT return is selected by default and applies to most businesses. If you are submitting for primary industries (such as agriculture, forestry or fishing), remember to change this.
To submit the VAT report, go to the top menu > Reports > Bookkeeping reports > For the Tax Administration > VAT report.
Before the VAT report can be submitted, the form must be validated against the Norwegian Tax Administration's systems. You have probably seen something similar when submitting your personal tax return.
This is an automated check that roughly verifies whether the VAT return looks correct before it is submitted. It does not necessarily mean the return will be approved.
When you click "Finish and validate", you will need to log in to Altinn with BankID. Afterwards, you will be told whether the form was validated without errors.
In some cases, you will be notified of discrepancies that need a closer look. For example, code 86 (services purchased from abroad with the right to deduct VAT) may have the opposite sign of what was expected (minus instead of plus). If you believe the figure is still correct, you will need to enter an explanation. If you have made a mistake, you can simply correct it in your accounts.
Once the form has been validated, you can submit the VAT return for the period in question. You do not need to log in to Altinn to enter a System ID or other information.
All you need to do is sign and submit the form with BankID, provided you have the right permissions in Altinn. If you use an accountant, make sure they have permission to submit on behalf of your business.
