Taxpayer Bill of Rights Act of 2012 - Amends the Internal Revenue Code to require the Secretary of the Treasury, in consultation with the National Taxpayer Advocate, to publish a summary statement of taxpayer rights and obligations.

Authorizes the Secretary to make grants to develop, expand, or continue volunteer income tax assistance programs to assist low-income taxpayers. Allows tax preparation program grant recipients to use grant funds to provide services related to financial literacy, asset development, and the establishment of savings accounts.

Increases the grant funding for low-income taxpayer clinics.

Requires the Secretary to: (1) prescribe regulations for the regulation of tax return preparers not otherwise regulated and to regulate the conduct of enrolled agents in their practice before the Internal Revenue Service (IRS); (2) require the annual registration of refund delivery product facilitators; and (3) furnish to the public the identity of any person who is an enrolled agent, attorney, or certified public accountant on file with the IRS, who is a tax return preparer, or who is registered as a refund delivery product facilitator.

Applies the penalty for understatements of taxpayer liability by tax return preparers to tax submissions other than tax returns or claims for refunds.

Prohibits the Secretary from filing a notice of lien with respect to any taxpayer unless: (1) the lien attaches to distrainable property, (2) the Secretary determines that the benefit to the government of filing outweighs the harm to the taxpayer and that the filing will not jeopardize the taxpayer's ability to comply with the internal revenue laws and to continue to secure funding to maintain business operations, (3) the Secretary notifies the taxpayer that the Secretary has determined to file such notice, and (4) the taxpayer is afforded an opportunity to appeal that determination. Requires the Secretary to consider specified factors in making such determination, including the amount due, the value of the taxpayer's equity in or rights to property, the taxpayer's compliance history, and the effect of the lien filing on the taxpayer's ability to obtain financing, generate future income, and pay current and future tax liabilities.

Prohibits persons licensed to practice before the Department of the Treasury from directly or indirectly offering or providing audit insurance.
