PTIN obligations

A preparer identifying number is an identifier the Code requires to appear on a return a paid preparer prepares. What follows is what the text says about obtaining it and using it.

An identifier is not a permission

An identifier answers the question who is this, for the purpose the rule names. Practice before the IRS, electronic filing participation and preparer status are separate objects with separate requirements, and holding a number for one of them settles nothing about the others.

What the authority says

Several of these rules are written with a scope: they reach certain persons, certain conduct, or certain returns. The scope is part of the rule, so we state who a provision reaches rather than turning it into a rule about everyone.

A signing tax return preparer is the individual who has the primary responsibility for the overall substantive accuracy of the preparation of a return or claim for refund.
A nonsigning tax return preparer is a preparer who is not a signing preparer but who prepares all or a substantial portion of a return or claim for refund.
A person who furnishes typing, reproducing or other mechanical assistance is not a tax return preparer.
A person who prepares a return for the employer by whom the person is regularly and continuously employed is not a tax return preparer with respect to that return, and other exceptions of the same kind apply.
Whether a schedule, entry or other portion is a substantial portion is determined on the facts, considering the size and complexity of the item relative to the taxpayer's gross income and the return as a whole.
Any return or claim for refund prepared by a tax return preparer shall bear an identifying number of the preparer, as the Secretary prescribes, for securing proper identification of the preparer.
The identifying number is a device for identifying the preparer to the Secretary.
Each return of tax or claim for refund prepared by one or more tax return preparers must include the identifying number of the preparer required by the regulations to sign the return or claim.
For returns filed after December 31, 2010, the identifying number of an individual tax return preparer is that individual's preparer tax identification number.
An individual must be authorized to render services under 31 U.S.C. § 330 and the regulations thereunder before obtaining or renewing a preparer tax identification number.
The preparer tax identification number must be applied for and renewed as prescribed by forms, instructions or other appropriate guidance.
A penalty applies to a tax return preparer who fails to furnish a completed copy of the return or claim for refund to the taxpayer.
A penalty applies to a tax return preparer who fails to sign a return or claim for refund that the preparer is required to sign.
A penalty applies to a tax return preparer who fails to furnish the preparer's identifying number as required.
A penalty applies to a tax return preparer who fails to retain a copy of the return or a list of returns prepared, as required.
Under § 6695(g), a penalty applies for each failure to comply with due-diligence requirements prescribed by the Secretary with respect to determining eligibility for, or the amount of, the earned income credit, the child tax credit and related credits, the American Opportunity Tax Credit, and head-of-household filing status.
