When submitting the VAT return to Altinn stops, Catacloud shows a message explaining what went wrong. Find the message you get below.
"A note must be attached explaining why deducted VAT has the opposite sign"
Altinn requires an explanation when deducted VAT has a negative sign (e.g. on a credit note for a purchase). The comment must be added on the line itself with the reversed sign – writing it in the Additional info/explanation for deviations field is not enough.
Open the VAT return under Accounting → Submissions → VAT return and find the line with the negative amount.
Click the speech-bubble icon (comment icon) to the right of the amount on that line.
Enter a short explanation, e.g. "Input VAT is negative as a result of a credit note on a cost.", and save the comment.
Click Resend to submit the VAT return to Altinn.
You'll find the steps with a screenshot in Comment on the VAT return: how to explain a reversed sign (negative input VAT).
If you can't add the comment or the submission still fails, contact us in the chat with the client name and period.
Other error messages on submission
Expired ID-porten login – You're taken to ID-porten automatically. Log in, and the submission continues by itself.
"Skatteetaten denied access …" or "Altinn denied access …" – Click Resend and log in to ID-porten. If the message comes back right after logging in, you're missing a role in Altinn that allows you to submit the VAT return for the organisation. Ask whoever manages Altinn roles for the organisation to give you the role. If the message appears under Receipt, the VAT return has already been submitted – don't submit it again.
"Altinn rejected the VAT return." – Altinn's own reason follows the message. Fix what Altinn points out, and click Resend.
"Altinn could not find the organisation …" – Check that the organisation number on the client is correct.
"Skatteetaten is unavailable right now …" or "Altinn is unavailable right now …" – The service is temporarily unavailable. Try again a little later.
"Skatteetaten could not validate the VAT return …" – Try again a little later. Contact us in the chat if the error doesn't go away.
"We could not confirm that Altinn received the VAT return …" – Don't resubmit straight away. First check in Altinn whether the VAT return for the period has been submitted. If it hasn't, click Resend. If it has, contact us in the chat with the client name and period.
"Could not fetch the receipt from Altinn …" – The VAT return has been sent, but Catacloud couldn't fetch the receipt. Don't submit the return again. You'll find the receipt in Altinn.
If the deadline is close, you can always submit the VAT return directly in Altinn/the Norwegian Tax Administration (Skatteetaten). You'll find the figures in the statement in Catacloud – you can use the Export button at the top. Afterwards you can mark the return as submitted in Catacloud: click the dropdown arrow next to Lock/Reopen period and select VAT report sent in manually.
