Confirm the correct taxpayer account and authorised user before starting a filing or registration task.

Keep an audit trail

Save submission receipts, certificates and correspondence, and follow the Tax Authority's current portal guidance.

Editorial note

General information only. Confirm current rules with the relevant authority.

Continue with country-specific guidance.
