Form 8275 Instructions: What It Protects and How to File

The instructions for Form 8275, the IRS Disclosure Statement, come down to this: attach the form to a timely filed return, complete Part I’s six-column grid identifying the item, write a factual and legal explanation in Part II, add Part III if the item came through a partnership or other pass-through entity, and confirm your position isn’t on the list of items the form cannot protect. Done correctly, the disclosure shields you from the 20% accuracy-related penalty on a resulting underpayment, provided your position has at least a reasonable basis in tax law.¹

What the Form Actually Protects

Form 8275 targets two slices of the Section 6662 accuracy-related penalty: underpayments from disregarding IRS rules such as revenue rulings and notices, and underpayments from a substantial understatement of income tax on non-tax-shelter items.² If you adequately disclose a position on Form 8275 and have a reasonable basis for it, the disclosed item is excluded from the understatement calculation, which can drop you below the penalty threshold.¹

Reasonable basis means your position is grounded in at least one recognized tax authority: a statute, regulation, revenue ruling, court case, or similar source. Practitioners often describe it as roughly a 20% likelihood of being sustained. A position that is merely arguable or built on a wishful reading of the law does not qualify.

Positions Form 8275 Cannot Protect

Check this list before you start filling boxes. The IRS instructions state that disclosure on Form 8275 cannot avoid the penalty for:

Negligence, meaning a failure to make a reasonable attempt to comply with the tax code.
Disregard of Treasury regulations. Those positions go on Form 8275-R instead.
Tax shelter items attributable to a partnership, entity, plan, or arrangement with a significant purpose of avoiding federal income tax.
Substantial or gross valuation misstatements, including non-arm’s-length pricing.
Tax benefits from transactions lacking economic substance under Section 7701(o).
Undisclosed foreign financial asset understatements.
Inconsistent estate basis reporting.

The economic substance exclusion is particularly steep. Undisclosed transactions lacking economic substance carry a 40% penalty, double the standard rate, and filing an amended return after the IRS contacts you about an examination won’t help.¹ If your position falls into any of these categories, Form 8275 is the wrong tool.³

Form 8275 or Form 8275-R

Pick the right form before you start. Form 8275 covers positions that aren’t contrary to a Treasury regulation, including positions contrary to a revenue ruling or an IRS notice. Form 8275-R, the Regulation Disclosure Statement, covers positions that directly challenge or contradict a Treasury regulation.⁴ A position contrary to a regulation must be a good-faith challenge to the regulation’s validity and still have a reasonable basis.⁵ Filing a position contrary to a regulation on Form 8275 does not satisfy the disclosure requirement, and you lose the protection.

Part I: Identifying the Item

Part I is a six-column grid that creates an audit trail from your disclosed position to the exact line of your return. Each row addresses one item, and every column must be filled in. If you’re claiming the same tax treatment for a group of similar items in a single tax year, you can describe the group as a whole instead of listing each one.²

Column (a), Rule or Regulation: enter the full citation for the rule you’re addressing, such as a specific revenue ruling number or statutory provision.
Column (b), Item Name: identify the item by name. If the item comes from a pass-through entity, label it as such. Items from different pass-through entities each require a separate Form 8275.
Column (c), Description: give a complete description. If column (b) says “entertainment expenses,” column (c) should list the actual items, such as theater tickets and catering costs.
Column (d), Form or Schedule: the form or schedule where the item appears, such as Schedule C or Form 1065.
Column (e), Line Number: the specific line on that form.
Column (f), Amount: the dollar amount of the disclosed item.

Part II: Your Facts and Legal Argument

Part II is the narrative. The IRS needs enough detail to understand three things: the identity and amount of the item, the relevant facts surrounding it, and the nature of the legal controversy.

Start with the facts, laying out the circumstances that affect the tax treatment. Then explain the legal issue those facts create and walk through your reasoning. If your position contradicts a revenue ruling, say specifically why the ruling doesn’t apply to your situation or why you believe it’s wrong on the facts. A vague reference to “disagreement with the IRS” is not enough. The explanation needs to show that you’ve identified authority supporting your position and can articulate a reasonable basis for it.

If Part II doesn’t give you enough space, continue in Part IV on page two or attach a continuation sheet. Any continuation sheet must include your name and taxpayer identification number.²

Part III: Pass-Through Entity Items

Complete Part III only when the item originated from a pass-through entity (a partnership, S corporation, estate, trust, regulated investment company, real estate investment trust, or real estate mortgage investment conduit) and the entity itself hasn’t already made the required disclosure on its own return.⁶

Line 1: full name, address, and ZIP code of the pass-through entity.⁶
Line 2: the entity’s Employer Identification Number.
Line 3: the entity’s tax year when the item originated. Watch for fiscal-year entities whose year differs from yours.
Line 4: where the entity filed its return. If you don’t know, check the Schedule K-1 you received. If the entity filed electronically, enter “e-file.”²

When You Don’t Need Form 8275 at All

The IRS publishes a yearly Revenue Procedure identifying items where proper completion of the return itself counts as adequate disclosure. For 2025 tax year returns, that guidance is Revenue Procedure 2026-12. If your item falls within that list and you’ve filled out the applicable forms and schedules correctly, you don’t need a separate Form 8275. Items involving complex or unusual facts that don’t fit the published guidance still require the form.²

One boundary worth flagging: if your position relates to a reportable transaction, Form 8275 by itself is not enough. Those disclosures run through Treasury Regulation Section 1.6011-4(d) and typically require Form 8886, Reportable Transaction Disclosure Statement, with its own filing requirements and deadlines.²

When and How to File

Attach Form 8275 to the original return it relates to. It must be filed by the return’s due date, including extensions.³ A late Form 8275 on an otherwise timely return will not give you penalty protection.

For electronic filers, tax preparation software handles the attachment and transmission as part of the e-filed return. Paper filers should place the form prominently with the return and mail it to the IRS service center listed in the instructions for the underlying return.

Two recurring-situation rules to keep in mind. Disclosures for carryback or carryover items only need to be filed with the return for the year the item first arose. Recurring items such as depreciation require a new Form 8275 for each tax year the item appears.²

If You Missed the Disclosure on Your Original Return

You may still be able to file Form 8275 with a qualified amended return. Under Treasury Regulation Section 1.6664-2(c)(3), an amended return qualifies if it’s filed before the earliest of three events: the date the IRS first contacts you about an examination, the date the IRS contacts a promoter connected to a tax avoidance activity you participated in, or, for pass-through items, the date the IRS contacts the pass-through entity about an examination.⁷ Once any of those events occurs, the window closes.

How Long to Keep the File

Keep a copy of every Form 8275 you file along with the supporting documentation: the legal authorities you relied on, the factual narrative, and any professional opinions. The IRS requires you to retain records supporting items on your return until the applicable period of limitations expires.⁸

For most taxpayers, that period is at least three years from the date you filed. If you underreport income by more than 25% of the gross income on your return, it extends to six years. For claims involving worthless securities or a bad debt deduction, keep records for seven years. If you never filed the return or filed a fraudulent one, there’s no expiration.⁸ A Form 8275 disclosure signals a position the IRS may question, so retaining the file on the longer side is the safer move.
