Above: Sample of IRS Form 8886 (Rev. December 2019) – Attach to your tax return and send a copy to OTSA for initial filings.
What Is IRS Form 8886?
Form 8886 discloses your participation in reportable transactions—arrangements the IRS identifies as having potential for tax avoidance or evasion. The purpose is transparency, not an automatic disallowance of tax benefits.
You must file a separate Form 8886 for each distinct reportable transaction (or group of substantially similar ones). Attach it to your federal tax return (e.g., Form 1040, 1065, 1120) for every year you participate.
Key fact: Even if the transaction is later deemed legitimate, proper disclosure protects against penalties and keeps the statute of limitations from extending indefinitely on listed transactions.
Who Must File Form 8886?
Any taxpayer required to file a federal tax return or information return must disclose if they participate in a reportable transaction. This includes:
- Individuals
- Trusts
- Estates
- Partnerships
- S corporations
- C corporations
Exceptions:
- Regulated investment companies (RICs) and vehicles 95%+ owned by RICs are generally exempt except for listed transactions or transactions of interest.
Participation occurs if your tax return reflects tax consequences, benefits, or losses from the transaction matching IRS definitions (detailed below). Pass-through entities trigger disclosure for partners/shareholders/beneficiaries based on their allocable share.
What Are Reportable Transactions? (5 Categories)
The IRS defines five categories under Treas. Reg. § 1.6011-4. You must check all that apply on Line 2 of Form 8886.
- Listed Transactions
Transactions the IRS has specifically identified as tax avoidance (e.g., via Notice 2009-59 or updates on IRS.gov). Participation: Your return shows the described tax consequences/strategy or you know the benefits derive from it. - Confidential Transactions
Offered under confidentiality (advisor limits disclosure of tax treatment/structure) with a minimum fee paid ($250,000 for corporations/partnerships/trusts with corporate owners; $50,000 otherwise). Fees include analysis, implementation, documentation, and unreasonable return-prep fees. - Transactions with Contractual Protection
You (or a related party) have the right to a full/partial fee refund if tax benefits fail, or fees are contingent on realizing those benefits. - Loss Transactions
Claim a §165 loss meeting thresholds (adjusted for salvage/insurance, over the transaction year + 5 succeeding years):- Individuals/trusts/estates/S corps/partnerships (non-corporate only): $2 million single year or $4 million combined ($50,000 for §988 foreign currency losses).
- Corporations (non-S) or corporate-partner partnerships: $10 million single year or $20 million combined.
- Transactions of Interest (TOI)
Emerging transactions the IRS flags for potential abuse but needs more data (post-November 1, 2006). Participation follows published guidance identifying classes of taxpayers.
Substantially similar transactions share expected tax consequences or strategies—broadly interpreted in favor of disclosure.
Prohibited tax shelter transactions (listed, confidential, or contractual protection) may also require Form 8886-T for tax-exempt entities.
How to File Form 8886: Step-by-Step Instructions?
- Complete the form fully (per instructions and Treas. Reg. § 1.6011-4(d)):
- Describe expected tax treatment, all potential benefits, tax structure, steps, parties, economic purpose, and any protections/limitations.
- Attach sheets if needed; no “information available upon request” statements (these trigger penalties).
- Attach to your tax return for each year of participation (including amended returns or tentative refunds like Form 1045/1139 for carrybacks).
- Send a copy to OTSA (initial year only, or when required for late-identified transactions):
- Mail: Internal Revenue Service, OTSA Mail Stop 4915, 1973 North Rulon White Blvd., Ogden, UT 84404
- Fax: 844-253-2553 (one per fax, ≤100 pages; include cover details)
- Must match the filed return exactly.
Special rules:
- Late K-1: 60-day extension for partners/shareholders.
- Transaction becomes listed/TOI later: 90-day OTSA filing (post-Aug 2, 2007 entries) or attach to next return (pre-Aug 3, 2007).
- E-filing: Still mail/fax exact paper copy to OTSA.
Protective disclosure: Check the box if uncertain—it still requires full completion.
Penalties for Failure to Disclose (Section 6707A)
Non-compliance is costly:
- Monetary penalty: 75% of the tax reduction from the transaction.
- Minimum: $5,000 (individuals) or $10,000 (others).
- Maximum (per year): $100,000/$200,000 for listed (individuals/others); $10,000/$50,000 for other reportable.
- Applies for missing attachment, no OTSA copy, or incomplete form.
- Accuracy-related penalty (Section 6662A): Increases to 30% (from 20%) for undisclosed reportable transaction understatements; no reasonable cause defense for listed transactions.
- Extended statute of limitations (Section 6501(c)(10)): Remains open for listed transactions until proper disclosure.
- Additional SEC reporting penalties possible.
Penalties stack with others and apply even to protective disclosures if incomplete.
