# Submit a reviewed quarterly VAT filing (/reference/oauth-submit-vat-draft)

Requires the latest revision and explicit acceptance of the declaration from VAT context. Preserves server-side ownership, period, tax-credit and authoritative settlement checks. Zero-liability filings need no invoice; positive liability requires existing payment evidence. Use links.portal for payment. Repeating a successful submission with the same revision returns the existing receipt. No charges are initiated by this endpoint.

Account deactivation revokes personal API keys, including Agent Keys, and OAuth authorizations. Account reactivation requires new API keys, including new Agent Keys, and consent; previously issued credentials remain invalid.
