6.2 Toegang door accountant

U kunt leestoegang tot uw CryptoTax.be-account verlenen aan een derde partij, zoals uw accountant of belastingadviseur, door vanuit uw accountinstellingen een uitnodiging te versturen. Met deze toegang kan de derde partij uw belastinggegevens inzien maar niet wijzigen. De rechtsgrondslag voor deze gegevensdeling is uw toestemming (AVG artikel 6, lid 1, onder a). U kunt deze toegang op elk moment intrekken via uw accountinstellingen, waarna de derde partij onmiddellijk alle toegang tot uw gegevens verliest.

Daarnaast kan een accountant die met uw mandaat uw fiscaal dossier beheert, op CryptoTax.be een beheerd cliëntdossier voor u aanmaken. In een beheerd dossier kan de accountant namens u databronnen toevoegen (walletadressen, exchange-koppelingen, CSV-bestanden), correcties aanbrengen op uw belastingdata en uw belastingrapport vastleggen. Heeft u al een CryptoTax.be-account met hetzelfde e-mailadres, dan wordt het beheerde dossier aan dat account gekoppeld. De rechtsgrondslag voor deze verwerking is de overeenkomst tussen u en uw accountant (AVG artikel 6, lid 1, onder b); de accountant bevestigt aan ons dat hij over uw mandaat beschikt. Accountants en hun teamleden zijn contractueel gebonden aan onze gebruiksvoorwaarden voor accountants, met strikte vertrouwelijkheids- en beveiligingsverplichtingen.

Vragen over een beheerd dossier, of wilt u een samenwerking beëindigen? Neem contact op met uw accountant of bereik ons via [email protected].
