Submitting to EMTA
File the Estonian KMD VAT return with EMTA: authorise Arvello in e-MTA, download the generated XML files and upload them at the portal in minutes.
Filing a KMD (the Estonian VAT return) has two parts in Arvello: a one-off authorisation that lets Arvello act for your company at EMTA — the Estonian Tax and Customs Board — and the routine of filing each period's return through e-MTA, EMTA's online portal.
The authorisation is granted inside e-MTA itself, by you. That's by design: e-MTA only lets a board member, or an accountant your company has authorised, hand out access to your tax affairs.
Authorising Arvello in e-MTA
Arvello asks for two machine-to-machine permissions, granted to its operating company Namasgo OÜ (registry code 16747054): one for sending KMD data and one for sending TSD data — the payroll declaration, covered under TSD returns. These permissions are what allow returns to be submitted directly over X-tee, Estonia's secure data-exchange layer. Granting them also verifies your identity, since e-MTA login requires Smart-ID, Mobile-ID or an ID card.
You'll meet this step at the start of the invoice setup wizard, and as an item on the dashboard checklist. It takes about two minutes:
Log in to e-MTA
Represent your company
Open access permissions
Find Namasgo OÜ
Enable both permissions
Verify in Arvello
Filing a return
ℹ️Direct submission
Once a return is approved and shows Ready to Submit (see Preparing a KMD return), Arvello has generated the official files for the period:
Download the files
Upload in e-MTA
Mark as submitted
Common questions
Verification failed, or the authorisation has expired
A freshly granted permission can take a few minutes to take effect — if Arvello reports "We couldn't confirm the permission yet", a short wait and a retry is often all it takes. If it still fails, check in e-MTA that the permission was granted while representing the company (not yourself), that both permissions are enabled, and that the start date isn't in the future. Permissions are listed in e-MTA under Settings → Access permissions; one that has been ended or has lapsed can be re-granted by repeating the steps above.
My submission was rejected
e-MTA validates the file at upload and shows the reason in the portal. The usual culprits are company details that don't match EMTA's records — check the registry code and VAT number in company settings, since both go into the XML — or a return already filed for that period. If the figures themselves need to change, the route is an amendment.
