What are Preparer Tax Identification Numbers (PTINs)?

What are Preparer Tax Identification Numbers (PTINs)?

A Preparer Tax Identification Number (PTIN) is a unique identification number that the Internal Revenue Service (IRS) assigns to tax preparers, including certified public accountants (CPAs), enrolled agents, attorneys, and other professionals who prepare federal tax returns for compensation. The PTIN is a requirement for anyone who prepares or assists in preparing federal tax returns for a fee. Even if a tax professional supervises the preparation of tax returns and does not personally input any data, they are still considered to be assisting in the preparation and must have a PTIN.

Why do I need a PTIN?

The primary purpose of PTINs is to provide a way for the IRS to track and regulate tax return preparers. By requiring tax professionals to obtain and use PTINs, the IRS aims to enhance the accuracy and integrity of the tax return preparation process. PTINs also help the IRS identify and communicate with tax preparers, ensuring that they are aware of their responsibilities and obligations. 

For tax professionals, having a PTIN is not just a regulatory requirement; it is also a mark of professionalism and credibility. It signifies that the preparer is authorized to assist taxpayers with their federal tax returns and is committed to upholding the standards set by the IRS.

There are a few exceptions to the PTIN requirement, such as non-credentialed tax return preparers who are supervised by a CPA, attorney, or enrolled agent. However, these exceptions are limited, and most individuals who engage in tax return preparation for compensation will need to obtain a PTIN.

The consequences of not having a PTIN can be severe. Tax professionals who fail to comply with the PTIN requirement may face penalties, sanctions, and restrictions on their ability to prepare federal tax returns. Additionally, taxpayers who use the services of a preparer without a valid PTIN may encounter issues with the accuracy and legitimacy of their tax returns.

The application process for obtaining a PTIN involves completing the IRS's online application and paying a fee. The IRS has designated an online system for PTIN applications, making it convenient for tax professionals to apply and receive their PTINs.

PTINs must be renewed annually, and the renewal process typically opens in the fall. Tax professionals are required to update their information and pay the renewal fee to maintain an active PTIN for the upcoming year. The fees associated with obtaining and renewing a PTIN are set by the IRS and are subject to change.

Compliance and Ethical Responsibilities with PTINs

The IRS has established regulations and guidelines to which PTIN holders must adhere. These regulations cover various aspects of tax return preparation, including recordkeeping, due diligence, and ethical conduct. PTIN holders are expected to stay informed about their obligations and comply with the IRS's requirements to maintain their PTIN status.

In addition to IRS regulations, PTIN holders have ethical responsibilities to their clients and the tax system as a whole. They are expected to provide competent and diligent services, maintain confidentiality, and avoid conflicts of interest. Failure to meet these ethical responsibilities can result in disciplinary actions and damage to the preparer's professional reputation.

Noncompliance with PTIN regulations can lead to serious consequences, including fines, suspension or revocation of the PTIN, and legal repercussions. Tax prep professionals must prioritize compliance with IRS rules and ethical standards to protect their clients and their standing in the tax preparation industry.


Preparer Tax Identification Numbers (PTINs) play a crucial role in the regulation and oversight of tax return preparers. They are essential for tax professionals who prepare federal tax returns for compensation, serving as a symbol of professionalism and a marker of compliance with IRS regulations. Understanding the significance of PTINs and fulfilling the associated responsibilities is vital for both tax professionals and taxpayers.

As tax season approaches, tax professionals need to ensure that their PTINs are current and that they are up to date with the latest IRS requirements. By doing so, they can demonstrate their commitment to ethical tax preparation practices and assure their clients that they are qualified and authorized to assist with their tax needs.
