Choose a plan and add a card; your first payment is due on day 8. If Ticke is not right for you, cancel in one click from your account before then.
If a payment is overdue, access switches to read-only immediately. You can request access to or deletion of your data at [email protected]. Data retention and deletion follow applicable legal obligations. Invoices Ticke issued to you and records we must keep by law, including records sent to the AEAT, are not deleted when you cancel or request deletion; they are restricted while retention is required. An export may not include every tax document or constitute a complete tax archive.
