Frequently asked questions
Can I revoke it later? Yes — at any time from suomi.fi/valtuudet → Annetut valtuudet. Filing will stop immediately once revoked.
What if I can't find the role in step 3? Search for "rajapinta" — this narrows the list significantly. Copy the full role name exactly using the button above.
Does this give Naapurin Nettishamaani access to my tax account? No. The role is scoped specifically to filing VAT declarations via the API. It cannot view, modify, or retrieve any other tax information.
