IRS Form 8278, Assessment and Abatement of Miscellaneous Civil Penalties, is an internal worksheet an IRS examiner completes to assess conduct-based penalties against tax return preparers, promoters of abusive tax shelters, and others who violate specific Internal Revenue Code sections. You don’t file it. It lands on your IRS account after an examination and produces a penalty notice demanding payment. If one of those notices just arrived, what matters is knowing which penalty the examiner used, whether the IRS followed the rules when assessing it, and how to push back.
What Penalties Form 8278 Covers
Form 8278 is used for “assessable penalties” — the kind the IRS can put on your account without first issuing a statutory notice of deficiency or going through Tax Court. They target specific misconduct, not arithmetic mistakes. Four Code sections do most of the work.
Section 6694: Preparer Understatement
A preparer who understates a client’s tax liability faces a two-tier penalty. For an unreasonable position lacking substantial authority, it’s the greater of $1,000 or 50 percent of the income the preparer earned from that return. For willful or reckless conduct, it’s the greater of $5,000 or 75 percent of that income.1Internal Revenue Service. Tax Preparer Penalties These figures are set by statute and are not indexed for inflation.
Section 6695: Administrative Preparer Failures
Section 6695 covers routine compliance slips — not signing the return, not giving the client a copy, missing the preparer identification number, and similar failures. For returns filed in 2026, each failure carries a $65 penalty with an annual cap of $32,500 per category. Two failures carry heavier consequences: improperly negotiating a client’s refund check costs $650 per check, and failing to perform due diligence on credits such as the Earned Income Credit or Child Tax Credit triggers a $650 penalty per failure, with no annual cap on either.2Internal Revenue Service. Rev. Proc. 2024-40
Section 6700: Promoting Abusive Tax Shelters
Someone who organizes or sells interests in an abusive tax shelter and makes false or fraudulent statements about its tax benefits owes a penalty equal to 50 percent of the gross income earned from that activity. For shelters involving gross valuation overstatements rather than false statements, the penalty is the lesser of $1,000 or 100 percent of gross income per activity.3Office of the Law Revision Counsel. 26 USC 6700 – Promoting Abusive Tax Shelters, Etc. There is no statute of limitations for a Section 6700 penalty. The IRS can assess it at any time.4Internal Revenue Service. Tax Shelter Promoter Investigations Under IRC 6700
Section 6701: Aiding and Abetting Understatement
A person who knowingly helps prepare any portion of a document that understates someone else’s tax liability owes $1,000 per document. If the document relates to a corporation’s tax, the penalty is $10,000 per document.5Office of the Law Revision Counsel. 26 USC 6701 – Penalties for Aiding and Abetting Understatement of Tax Liability
How the Assessment Reaches Your Account
An examiner fills in Form 8278 with the identifying information for the person being penalized, the tax periods, the specific Code section, and the calculated amount.6Internal Revenue Service. Internal Revenue Manual 20.1.9 – International Penalties – Section: 20.1.9.2.2 Penalty Assessment Before the penalty can be assessed, a supervisor must personally approve the determination in writing. Section 6751(b) requires that written sign-off for most penalties, with narrow exceptions for penalties automatically calculated by computer and certain additions to tax for failure to file or pay.7Office of the Law Revision Counsel. 26 USC 6751 – Procedural Requirements If your penalty was assessed without that approval, that failure is itself a basis to challenge the whole assessment.
Once approved and posted, the IRS system generates a notice. Individuals receive Notice CP15 (Notice of Penalty Charge). Businesses receive Notice CP215 (Notice and Demand).8Internal Revenue Service. Internal Revenue Manual 20.1.10 – Miscellaneous Penalties – Section: 20.1.10.4.2.2 Assessment by Exam on Form 8278 The notice states the penalty amount, the Code section, and how to respond. Keep it. The return address and the 30-day response window on the notice both matter if you plan to dispute the penalty.
Requesting Abatement on Form 843
You can ask the IRS to reduce or eliminate the penalty by filing Form 843, Claim for Refund and Request for Abatement. If you’re responding to a penalty notice, mail Form 843 to the return address printed on that notice. Otherwise, send it to the service center where you’d normally file your current-year return.9Internal Revenue Service. Instructions for Form 843 (12/2024) Attach a written statement explaining why the penalty should be removed, and back it up with documents.
The most common ground is reasonable cause. You have to show you exercised ordinary business care and prudence but still could not comply because of circumstances beyond your control.10Internal Revenue Service. Internal Revenue Manual 20.1.1 – Introduction and Penalty Relief – Section: 20.1.1.3.2.2 Ordinary Business Care and Prudence Categories the IRS recognizes include:
- Serious illness or death that prevented you from meeting a filing or compliance obligation.
- A natural disaster or casualty that disrupted your ability to comply.
- Inability to obtain necessary records despite a good-faith effort.
Send tangible evidence with your letter. Medical records, insurance claims, police reports, or correspondence showing your efforts to comply carry far more weight than a narrative alone.11Internal Revenue Service. Internal Revenue Manual 20.1.1 – Introduction and Penalty Relief – Section: 20.1.1.3.6.5 Documentation
One boundary worth knowing: the IRS’s First-Time Abate program does not apply to Form 8278 penalties. That relief covers only failure-to-file, failure-to-pay, and failure-to-deposit penalties, not the conduct-based penalties assessed here.12Internal Revenue Service. Administrative Penalty Relief Don’t waste a request arguing a clean prior record alone.
Appealing a Denial
If the IRS denies your abatement request, you can take the dispute to the IRS Independent Office of Appeals. You generally have 30 days from the date of the denial letter to request an Appeals conference.13Internal Revenue Service. Penalty Appeal Appeals officers work separately from the examination division and reconsider both the legal basis for the penalty and your reasonable cause arguments. Many penalty disputes end at this stage. Come with organized documentation and be ready to walk through your reasonable cause showing point by point.
Going to Court
Because Form 8278 penalties are assessable rather than deficiency-based, you generally cannot petition the U.S. Tax Court for prepayment review. You must pay the full penalty first, then file a refund suit in a U.S. District Court or the U.S. Court of Federal Claims.14Taxpayer Advocate Service. Strengthen Taxpayer Rights in Judicial Proceedings The Justice Department’s Tax Division represents the government, and the litigation costs and discovery burdens run well above what you’d see in Tax Court. This path typically makes sense only when the penalty is large enough to justify a tax attorney, whose hourly rates in federal penalty disputes commonly run $400 to $850.
Statute of Limitations
How long the IRS has to assess depends on the Code section. Most assessable penalties fall under the general three-year period in Section 6501, measured from the date the underlying return was filed. Section 6700 promoter penalties are the outlier. They carry no limitations period, so the IRS can assess them at any point after the prohibited activity.4Internal Revenue Service. Tax Shelter Promoter Investigations Under IRC 6700 Once any penalty is assessed, the IRS has ten years to collect. If the IRS assessed your penalty outside the applicable limitations period, raise that defense in your abatement request or at Appeals. An untimely assessment is void regardless of the merits.
