Which of the following methods permits the disclosure of taxpayer information?

The method that permits the disclosure of taxpayer information is through a taxpayer request. When a taxpayer requests their own information, they have the right to access it under various tax privacy laws and regulations. This is essential as it empowers taxpayers to review their records and ensures transparency regarding the information the government holds about them.

In contrast, computer processing, public advertisement, and third-party sharing without consent do not generally permit the disclosure of taxpayer information due to strict confidentiality and privacy laws, such as those outlined in the Internal Revenue Code. These laws are designed to protect taxpayer information from being disclosed without appropriate legal grounds or consent, maintaining the integrity and privacy of the taxpayer's financial data.
