Consent to disclosure of tax return information is a separate written document provided by a taxpayer that grants a tax return preparer permission to reveal (disclose) specific tax return information to another person. This permission is required when the disclosure is for any purpose not specifically authorized by law or regulation, such as assisting in the preparation and filing of the return.
To be valid, the consent must be knowing and voluntary, signed and dated by the taxpayer. It must clearly identify the intended purpose, the specific recipient(s), and the specific information being disclosed. An “opt-out” mechanism is not permitted; consent requires the taxpayer’s affirmative consent to each disclosure. Importantly, if consent is granted, federal law may not protect the information from further use or distribution by the recipient.
The consent is generally valid for one year from the date of signature, unless the taxpayer specifies a different duration.
