Tax return data is sensitive financial information that, once deleted, cannot be recovered. The irreversible nature of the operation and the sensitive nature of the data being deleted makes this a Destructive category threat.

From the tool's own definition: "Tool description states 'Securely delete tax return data after filing. This is irreversible.' The explicit use of 'delete' and 'irreversible' directly indicates destructive capability."
