Why protect tax documents?

Tax documents contain vital financial details, like your income, tax ID, and deductions. If someone else gets hold of this information, they could use it for identity theft or fraud. Protecting your tax data keeps you safe from financial trouble and maintains your privacy.

Can't I just email tax documents?

Sending tax documents over email without proper protection is risky. Hackers could steal your financial or personal information. Encrypting your emailed documents can help you keep your tax details safe from cyber threats.

* How do we calculate sensitivity ratings?

We calculate sensitivity ratings based on the type, volume, and potential misuse of the information contained in each document.

Here’s how it works:

Type of Information

Documents containing highly sensitive details—such as personal identifiers, financial data, legal records, or biometric information—receive higher ratings.

Volume of Sensitive Information

The more sensitive details a document contains, the higher the score. For example, a tax document with extensive personal and financial data scores higher than a single-page appraisal.

Likelihood and Impact of Misuse

Documents that pose a greater risk if intercepted—like credit card details or bank statements—receive higher ratings. We also consider the consequences of a breach, such as fraud or identity theft.

Audience and Context

Some documents, like asylum applications or legal case files, are rated higher due to the severe personal, professional, or legal consequences of exposure.

Scoring Scale

85–100: Highly sensitive, with significant risk if exposed (e.g., credit card details, biometric data).

70–84: Moderately sensitive, containing private or exploitable information (e.g., tax documents, bank statements).

Below 70: Lower sensitivity, but still requiring secure handling (e.g., property appraisals).

This method ensures our sensitivity ratings accurately reflect the level of protection needed for each document type.
