Every paid tax preparer who holds a Preparer Tax Identification Number (PTIN) is subject to a body of federal law that imposes monetary penalties for specific conduct. These are IRS tax preparer penalties: civil assessments the IRS can impose directly on the preparer, independent of any tax deficiency the client owes. They are not hypothetical. The IRS operates an active preparer compliance program and uses PTIN data, return-level analytics, and on-site compliance visits to identify penalty exposure.
This guide maps the full penalty landscape for independent PTIN holders in 2026: the civil penalties assessable by the IRS under the Internal Revenue Code, how they differ from the separate administrative sanctions the IRS Office of Professional Responsibility (OPR) can impose under Circular 230, the current dollar amounts for each penalty category, the statute of limitations for each, and the procedural path if you are assessed.
All penalty amounts cited in this guide are subject to annual inflation adjustment where noted. Verify current figures at IRS.gov before each filing season. This guide is informational and does not constitute legal or tax advice. For questions specific to your practice or a pending assessment, consult a qualified tax professional or attorney.
Civil Penalties vs. Circular 230 Sanctions: Two Separate Systems
The penalties covered in this guide are IRC civil penalties. They are codified in the Internal Revenue Code, assessed by the IRS examination function, and collectible the same way a tax liability is collectible. A preparer who fails to pay an assessed IRC penalty faces collection action, not just a professional consequence.
Circular 230 sanctions are a separate and parallel system. Circular 230 is the Treasury Department regulation governing the practice of representatives before the IRS. Sanctions under Circular 230 are administrative in nature: they are imposed by the OPR through a disciplinary proceeding and can include censure, suspension, or disbarment from practice before the IRS. The Circular 230 guide covers OPR sanctions in full.
The two systems are independent but not mutually exclusive. The same conduct can trigger both an IRC civil penalty assessment and a Circular 230 proceeding. A preparer who willfully understates a client's liability under IRC 6694(b), for instance, faces the IRC monetary penalty from the IRS examination function and may simultaneously face a referral to OPR for a Circular 230 proceeding. In egregious cases, criminal referral under IRC 7206 or other criminal statutes is also possible, though that is a separate proceeding outside the scope of this guide.
For preparers who are not enrolled practitioners (CPAs, attorneys, enrolled agents, enrolled retirement plan agents, or enrolled actuaries), Circular 230 applies only to the extent they appear before the IRS as unenrolled representatives. But the IRC civil penalties apply to every paid preparer who holds a PTIN, regardless of credential level.
IRC Section 6694(a): Unreasonable Position
Section 6694(a) imposes a penalty on any tax return preparer who prepares a return or claim for refund that includes an understatement of liability due to an "unreasonable position." An unreasonable position, for purposes of this section, is one that does not meet the applicable legal standard for taking that position on the return.
Penalty amount
The penalty under Section 6694(a) is the greater of: (1) $1,000, or (2) 50 percent of the income derived (or to be derived) by the preparer from preparing the return or refund claim. Verify current amounts at IRS.gov, as statutory amounts may be subject to adjustment.
The position standards: substantial authority and more likely than not
Whether a position is "unreasonable" turns on two standards that apply in different circumstances. Understanding which standard governs your return is essential before taking a position that the IRS might challenge.
- Substantial authority (the baseline standard). For most positions, the preparer must have substantial authority for the treatment reflected on the return. Substantial authority is a lower standard than "more likely than not" correct: it exists when the weight of authorities supporting the position is substantial compared to the weight of those opposing it. It is higher than a "reasonable basis" standard. If substantial authority exists and the position is disclosed (or if the position satisfies the realistic possibility of success standard for disclosed positions), the 6694(a) penalty does not apply.
- More likely than not (the higher standard for tax shelter and reportable transaction positions). For positions involving tax shelters or reportable transactions, the standard is elevated: the preparer must reasonably believe that the position is more likely than not the correct treatment under applicable law. "More likely than not" means a greater than 50 percent probability of being upheld on the merits. This is a materially harder standard to satisfy and applies regardless of whether the position is disclosed.
The 6694(a) penalty is reduced or eliminated if the preparer had reasonable cause and acted in good faith. Reasonable cause is evaluated based on all facts and circumstances. Reliance on incorrect client-provided information, without independent reason to question it, can support a reasonable cause defense. Willful blindness does not.
IRC Section 6694(b): Willful or Reckless Conduct
Section 6694(b) addresses the more serious end of preparer misconduct. Where 6694(a) covers unreasonable positions taken without fraudulent intent, 6694(b) targets willful attempts to understate tax liability and reckless or intentional disregard of rules and regulations. The distinction matters because the penalty amounts and the procedural consequences are significantly more severe.
Penalty amount
The penalty under Section 6694(b) is the greater of: (1) $5,000, or (2) 75 percent of the income derived (or to be derived) by the preparer from preparing the return or refund claim. Verify current amounts at IRS.gov. There is no reasonable cause exception to 6694(b): the conduct itself is the violation.
No statute of limitations
Unlike Section 6694(a) and most Section 6695 penalties, there is no statute of limitations for the assessment of a 6694(b) penalty. The IRS can assess the willful or reckless conduct penalty at any time after the return is prepared. This is among the most consequential distinctions between the two tiers of Section 6694 exposure.
What triggers the willful or reckless standard
"Willful" conduct means a conscious intent to understate the client's liability. "Reckless" conduct does not require intent: it is present when the preparer takes a position in conscious disregard of, or with reckless indifference to, the rules and regulations. A pattern of repeatedly claiming positions the preparer knows to be unsupportable, or of ignoring clear legal authority prohibiting a position while preparing returns for compensation, satisfies the recklessness standard even in the absence of a specific fraudulent intent. Preparers facing 6694(b) assessments are also likely to face parallel Circular 230 referrals and, in egregious cases, criminal referral.
IRC Section 6695: Mechanical Preparer Penalties (2026 Amounts)
Section 6695 imposes penalties for specific procedural failures that are distinct from the substantive return position penalties in Section 6694. These are mechanical violations: the preparer either did or did not comply with a specific, observable requirement. The penalties are per-failure and per-return; they accumulate across a filing season. All dollar amounts below reflect 2026 figures. Most are subject to annual inflation adjustment -- verify current amounts at IRS.gov before each filing season.
Failure to furnish copy to taxpayer (IRC 6695(a))
A preparer who fails to furnish a copy of the completed return to the taxpayer at or before the time the return is signed by the taxpayer is subject to a penalty of $60 per failure. The per-season maximum is $31,500. (Subject to annual inflation adjustment; verify at IRS.gov.)
Failure to sign return (IRC 6695(b))
A preparer must sign every return they prepare for compensation, either manually or by electronic signature. The penalty for failing to sign is $60 per return, with a per-season maximum of $31,500. (Subject to annual inflation adjustment; verify at IRS.gov.) This is not a technicality: the signature requirement is how the IRS identifies the preparer of record. A preparer who consistently omits their signature also makes it harder for the IRS to identify them -- which the IRS treats as an independent compliance concern.
Failure to include PTIN (IRC 6695(c))
Every paid preparer must include their current PTIN on every return they prepare. The penalty for omitting the PTIN is $60 per return, with a per-season maximum of $31,500. (Subject to annual inflation adjustment; verify at IRS.gov.) A PTIN that has lapsed because the preparer did not renew by December 31 is treated as no PTIN for this purpose. The 2026 PTIN fee is $18.75 ($10.00 IRS user fee plus $8.75 contractor fee); verify the current fee at IRS.gov before applying.
Failure to retain copy or list (IRC 6695(d))
A preparer must either retain a copy of every return prepared, or maintain a list showing the taxpayer's name and identifying number for each return. Retention is required for three years after the close of the return period. Failure to retain either a copy or the list is subject to a penalty of $60 per failure, with a per-season maximum of $31,500. (Subject to annual inflation adjustment; verify at IRS.gov.)
Negotiating client's refund check (IRC 6695(f))
A preparer is prohibited from endorsing or otherwise negotiating a refund check issued to a client. Violation of this prohibition is subject to a penalty of $600 per check. (Subject to annual inflation adjustment; verify at IRS.gov.) Note that bank product arrangements -- where the client's refund flows through a bank disbursement product -- are governed by separate rules and do not constitute endorsing the client's refund check for this purpose, provided the arrangement complies with applicable bank product disclosure and consent requirements.
EITC, CTC, AOTC, and HOH due diligence failure (IRC 6695(g))
A preparer who fails to comply with the due diligence requirements for claims of the Earned Income Tax Credit, the Child Tax Credit or Additional Child Tax Credit, the American Opportunity Tax Credit, or head-of-household filing status is subject to a penalty of $650 per failure per return as of 2026. This amount is subject to annual inflation adjustment; verify the current figure at IRS.gov before each filing season. The penalty applies separately for each credit or status on the return where due diligence was not met. A single return with EITC and CTC due diligence failures can generate two separate $650 penalties. The EITC due diligence and Form 8867 guide covers the four specific requirements in full.
IRC Sections 6700 and 6701: Promoter and Aider-Abettor Penalties
Sections 6700 and 6701 reach conduct beyond the preparation of an individual return. They apply to preparers and other persons who promote abusive tax shelters or who assist others in making understatements on their returns.
Section 6700: Promoting abusive tax shelters
Section 6700 imposes a penalty on any person who organizes or participates in the sale of a plan or arrangement if that person makes a statement they know or have reason to know is false or fraudulent regarding the tax benefits of the plan, or if the plan involves a gross valuation overstatement. The penalty is $1,000 per activity (or, if less, 100 percent of the gross income derived from the activity). Where the violation involves a statement about a reportable transaction, the penalty is $200 per activity. Verify current amounts at IRS.gov.
For an independent preparer, Section 6700 exposure most commonly arises from participating in the marketing of questionable tax products (such as inflated charitable contribution arrangements, fraudulent conservation easements, or captive insurance arrangements that lack economic substance) or from making representations about a client's tax position in connection with a plan being sold to multiple investors or clients.
Section 6701: Aiding and abetting understatements
Section 6701 imposes a penalty on any person who aids, assists, procures, or advises with respect to the preparation of any portion of a return, affidavit, claim, or other document, if that person knows (or has reason to believe) that the document will be used in connection with a material matter arising under the internal revenue laws and that it will result in an understatement of another person's tax liability. The penalty is $1,000 per document ($10,000 if the document relates to a corporate return). Verify current amounts at IRS.gov.
Unlike Section 6694, which requires that the preparer have signed the return, Section 6701 applies to any person who assists with the preparation of a document, whether or not they sign it. This means a preparer who assists an unlicensed or non-signing colleague with a fraudulent return position can face a 6701 penalty even if their name does not appear on the return.
IRC Section 7216: Civil and Criminal Penalties for Unauthorized Disclosure
Section 7216 governs the use and disclosure of tax return information by preparers. It is a privacy statute, not a return-accuracy statute. A preparer who discloses or uses a client's tax return information for any purpose other than those specifically permitted by Section 7216 and its regulations is subject to civil and criminal penalties, regardless of whether the return itself was prepared correctly.
The criminal penalty under Section 7216 is a misdemeanor: up to one year in prison and a fine of up to $1,000. Civil penalties are also available. Consent requirements, permitted disclosures, and the full scope of Section 7216 obligations are covered in the dedicated IRC 7216 privacy guide. Every preparer who uses software that shares return data with third-party products (such as bank product providers, marketing platforms, or cloud storage services) should review that guide before onboarding any vendor. The WISP data security guide covers the FTC Safeguards Rule and Written Information Security Plan requirements that operate alongside Section 7216.
How the IRS Identifies Non-Compliant Preparers
Understanding how the IRS locates penalty exposure is as practically important as knowing the penalty amounts. The IRS does not rely on chance discovery. It uses a structured set of data-driven and compliance-program tools to identify preparers who warrant closer review.
PTIN data matching
Every return prepared for compensation must carry the preparer's PTIN. The IRS processes PTIN data across the entire return population, which means it can aggregate every return prepared by a given PTIN holder and analyze them as a portfolio. A preparer who signs 500 returns a season has, in effect, given the IRS a dataset of 500 returns to analyze for patterns. Anomalies that would not be visible in a single return become statistically significant at volume.
DIF scoring and return selection
The IRS uses the Discriminant Information Function (DIF) system to score returns for audit potential. Returns prepared by a specific PTIN holder that consistently generate high DIF scores (indicating a higher-than-average probability of underreporting) are a signal that focuses IRS attention on the preparer, not just the individual client. A preparer whose portfolio of returns produces DIF-driven audit rates significantly above average for their geography and client type is likely to attract an IRS preparer review.
The preparer compliance program
The IRS operates a dedicated preparer compliance program that conducts on-site visits to preparers with identified compliance concerns. These visits can include a review of the preparer's procedures, a request to produce due diligence records for specific returns, and an assessment of whether the preparer's practice structure reflects the required compliance controls. Preparers with high concentrations of EITC, CTC, or AOTC returns are disproportionately likely to receive compliance visits, because those returns carry the highest per-failure penalty exposure under Section 6695(g).
Statute of Limitations for Preparer Penalties
The statute of limitations for IRS tax preparer penalties is penalty-specific. Knowing which period applies to which penalty matters for understanding your exposure window and your ability to contest an assessment.
- Section 6694(a) and Section 6695 penalties. The IRS generally has three years from the return due date (or the date of filing, if later) to assess penalties under Section 6694(a) and most Section 6695 penalties. For a return due April 15, 2026, the three-year assessment period would ordinarily run through April 15, 2029. Extensions of the client's return filing deadline do not automatically extend the preparer penalty statute. Verify current rules at IRS.gov.
- Section 6694(b) penalties (willful or reckless conduct). There is no statute of limitations for assessment of the willful or reckless conduct penalty under Section 6694(b). The IRS may assess this penalty at any time after the return is prepared. This unlimited window is a major reason why a 6694(b) finding carries consequences beyond the dollar amount: it creates indefinite exposure for every return in a preparer's history that involved willful or reckless conduct.
- Section 6700 and 6701 penalties. The statute of limitations for Section 6700 and 6701 penalties runs three years from the later of the date the return was filed or the return due date. Verify current rules and any applicable extensions at IRS.gov.
How to Respond If You Are Assessed a Preparer Penalty
An IRS preparer penalty assessment is not a final and unappealable determination. Preparers have procedural rights, and those rights are most effectively exercised promptly after the assessment notice arrives. This is a situation where consulting a qualified tax professional or tax attorney before responding is strongly advisable.
IRS Independent Office of Appeals
A preparer who disagrees with a penalty assessment can request review by the IRS Independent Office of Appeals. Appeals is a separate function within the IRS that operates independently of the examination function. The Appeals process gives the preparer an opportunity to present their factual and legal arguments to an Appeals Officer who was not involved in the original assessment decision. Many penalty assessments are reduced or eliminated through the Appeals process when the preparer can demonstrate reasonable cause, good faith reliance on authoritative sources, or factual inaccuracies in the IRS's penalty determination.
To preserve the right to Appeals, the preparer generally must file a written protest within 30 days of the IRS letter proposing the penalty. The protest must state the specific items with which the preparer disagrees, the factual basis for the disagreement, and the legal or regulatory authority supporting the preparer's position. Missing the protest deadline can forfeit the right to an administrative appeal before the penalty is formally assessed.
Penalty abatement for reasonable cause
Section 6694(a) penalties and Section 6695 penalties (other than the Section 6695(g) due diligence penalty in some circumstances) are subject to abatement if the preparer can demonstrate reasonable cause and good faith. Reasonable cause exists when the preparer exercised ordinary business care and prudence but was nonetheless unable to comply. Common reasonable cause arguments for 6694(a) include reliance on incorrect information provided by the client without independent reason to question it, reliance on a qualified legal or tax opinion, and good faith misinterpretation of a complex or unsettled area of law.
The strength of a reasonable cause defense is directly proportional to the quality of documentation. A preparer who can produce client interview notes, contemporaneous research, and a clear record of the basis for the position taken is in a materially stronger position than one who can only offer a reconstructed narrative. This is one of the core reasons why maintaining complete records at the time of return preparation matters. E&O insurance for tax preparers may also provide coverage for penalty-defense costs, depending on policy terms; review your policy before a penalty dispute escalates.
Tax Court and refund suit options
If the preparer pays the assessed penalty and believes it was incorrectly assessed, they can file a claim for refund and, if denied, bring a refund suit in federal district court or the Court of Federal Claims. Alternatively, in some circumstances, a preparer can challenge a Section 6694 penalty in the Tax Court. The procedural path varies by penalty type and amount; consult a tax attorney to evaluate which forum and strategy fits the specific situation.
9 Workflow Controls That Reduce Preparer Penalty Exposure
The penalties in Sections 6694 and 6695 are not random events. They follow identifiable process failures. The following nine controls address the failure modes the IRS penalty program consistently finds in non-compliant practices. None of them require extraordinary measures: they are the baseline of a professionally operated tax preparation practice.
Renew your PTIN before December 31 every year
A lapsed PTIN means every return you sign after the expiration date carries a Section 6695(c) penalty exposure. The renewal window opens each October. The 2026 PTIN fee is $18.75; verify the current fee at IRS.gov. Set a calendar reminder for October 1 and confirm the renewal is complete before November 1. Do not rely on email reminders from the IRS system; log in and confirm.
Use software that auto-populates your PTIN on every return
Manual PTIN entry on every return creates a per-return omission risk. Tax preparation software that pulls your PTIN from the preparer profile and inserts it automatically on every return eliminates that exposure at the system level. TaxWise auto-populates the EFIN and PTIN from the preparer setup, so the Section 6695(c) risk is handled at the configuration step, not the return-by-return step.
Implement a structured client intake and interview process
The knowledge standard under Section 6695(g) and the substantiation requirement under Section 6694(a) both depend on what you asked and what the client told you. A written intake form that covers income sources, dependents, filing status, and any new circumstances (with a specific field for the client's signature confirming they have answered accurately) creates a contemporaneous record that supports both your compliance and your defense if challenged.
Run the Form 8867 checklist as a live interview, not a post-hoc form
Completing Form 8867 from memory after the interview, or from the client's self-reported summary, does not satisfy the due diligence requirement. The form should reflect an actual inquiry conducted during return preparation. If your software integrates Form 8867 into the return workflow (as TaxWise does), walk through each section with the client present and document the responses at that time.
Retain a copy of every return for three years
The Section 6695(d) record-keeping requirement is satisfied either by retaining a copy of the return or by maintaining a client list with identifying numbers. Retaining the actual return is the more defensible approach, because the copy is also the due diligence record for the Form 8867 and interview notes. A practice management system or cloud storage solution that automatically archives each return at transmission removes this from the manual checklist entirely.
Document your legal authority for every non-obvious position
The "substantial authority" standard for Section 6694(a) requires that the weight of authority support the position. For any position that a reasonable examiner might question, keep a contemporaneous note of the authority you relied on: the statute, regulation, revenue ruling, case, or other source. A two-sentence note in your file at the time of preparation is far more credible than a reconstructed explanation after the IRS raises the issue.
Never sign returns without personally reviewing the positions taken
A preparer's PTIN signature certifies that, to the best of their knowledge, the return is true, correct, and complete. Signing returns that were assembled by an unlicensed assistant without review, or signing large volumes of returns at speed without confirming the positions, creates Section 6694 and Section 6695 exposure for every return signed. The signature is not a formality: it is a legal representation that carries monetary consequences.
Review your Section 7216 consent procedures annually
If your practice uses any third-party services that receive client tax return information (bank product providers, cloud storage, marketing tools, or referral networks), confirm annually that the appropriate Section 7216 consent forms are in place and that the third-party's use of the data is within the scope of the consent. Review the IRC 7216 guide for current consent requirements. Update your Written Information Security Plan if any vendors or data flows have changed.
Carry E&O insurance and know what it covers
Errors and omissions insurance for tax preparers can cover both the cost of defending a penalty assessment and, depending on policy terms, certain penalty payments. An uninsured preparer facing a six-figure Section 6695(g) exposure in a high-volume EITC practice is bearing that risk personally. Review the tax preparer E&O insurance guide for what policies cover, what they exclude, and how claims-made vs. occurrence form policies work for preparer liability.
