What Form 8886 Is For

Form 8886 is the IRS's way of keeping tabs on complex tax transactions that could potentially reduce your tax bill in ways the government wants to monitor. Think of it as a "heads up" form—you're notifying the IRS about certain financial moves you've made, not necessarily admitting you did anything wrong.

The form applies to what the IRS calls "reportable transactions"—a category that includes everything from transactions the IRS has specifically flagged as problematic (called "listed transactions") to deals involving large losses, confidential tax strategies you paid significant fees for, or arrangements where you can get your advisor fees refunded if the tax benefits don't work out. Anyone can be required to file: individuals, trusts, estates, partnerships, S corporations, or regular corporations. If you participated in one of these transactions and file a federal tax return, Form 8886 is likely required.

The key point: filing this form doesn't automatically mean you're in trouble. It simply means you engaged in a transaction the IRS considers worth watching. Your tax benefits might be perfectly legitimate—disclosure is just mandatory. IRS.gov - About Form 8886

When You’d Use Form 8886 (Including Late and Amended Filings)

You must attach Form 8886 to your tax return for each year you participated in a reportable transaction. The form goes with your original return, but there are several situations requiring additional filings:

Amended Returns

If you file an amended return that reflects a reportable transaction, attach Form 8886 to the amended return as well.

Carryback Situations

If your reportable transaction generates a loss or credit you're carrying back to prior years, attach Form 8886 to Form 1045 (for individuals) or Form 1139 (for corporations) when applying for a tentative refund, or to amended returns for those carryback years.

Late Discovery

If a transaction becomes classified as "listed" or as a "transaction of interest" after you've already filed your return, you must file Form 8886 within specific timeframes. For transactions entered into after August 2, 2007, you have 90 days from the listing date to file with the Office of Tax Shelter Analysis (OTSA). For earlier transactions, attach Form 8886 to your next tax return after the listing.

Loss Transactions

If losses from a transaction reach the reporting thresholds over multiple years, you must file Form 8886 in the first year the threshold is met and in subsequent years reflecting those losses. Instructions for Form 8886 (Rev. August 2017)

Key Rules or Details for 2017

The 2017 version of Form 8886 requires reporting five categories of transactions:

1) Listed Transactions

These are specific tax avoidance schemes the IRS has publicly identified through notices or regulations. The IRS maintains an updated list at IRS.gov.

2) Confidential Transactions

These involve tax strategies offered under conditions of confidentiality where you paid minimum fees of $250,000 (for corporations) or $50,000 (for individuals, partnerships, and most other entities). Confidentiality means your advisor restricted your ability to disclose the tax structure to protect their proprietary strategy.

3) Transactions with Contractual Protection

You have the right to a full or partial fee refund if the tax benefits don't materialize, or your fees are contingent on realizing tax benefits.

4) Loss Transactions

You're claiming Section 165 losses meeting these thresholds:

• Individuals/trusts: $2 million in one year or $4 million combined (or $50,000 from foreign currency transactions)
• Corporations (excluding S corporations): $10 million in one year or $20 million combined
• Partnerships and S corporations: $2 million in one year or $4 million combined (with higher thresholds if all partners are C corporations)

5) Transactions of Interest

The IRS identifies these as potentially problematic but needs more information before deciding whether to classify them as tax avoidance schemes.

Dual Filing Requirement

For initial year filings, you must attach Form 8886 to your tax return and send an exact copy to the Office of Tax Shelter Analysis (OTSA) at: Internal Revenue Service, OTSA Mail Stop 4915, 1973 Rulon White Blvd., Ogden, Utah 84201. Instructions for Form 8886 (Rev. August 2017)

Step-by-Step (High Level)

Step 1: Determine if You Participated

Review the five reportable transaction categories. If your tax return reflects tax consequences or benefits from any qualifying transaction, you likely need to file.

Step 2: Gather Comprehensive Information

You'll need transaction names, dates you entered the transaction, reportable transaction numbers (if provided by advisors), details about entities involved, advisor information, and fee amounts. Most importantly, you need a complete description of the transaction structure.

Step 3: Complete Form 8886 Thoroughly

This isn't a form where you can write "details available upon request." Every line requiring information must be completed. Describe the expected tax benefits, explain the transaction step-by-step, identify all parties involved, and attach supporting documentation as needed.

Step 4: Attach to Your Tax Return

Include Form 8886 with your Form 1040, 1120, 1065, 1120S, or other applicable return for each year you participated.

Step 5: File Separately with OTSA

If this is the first year you're disclosing this particular transaction, simultaneously send an exact copy of Form 8886 to OTSA at the Ogden, Utah address. As of 2020, the IRS accepts this copy via fax to 844-253-2553.

Step 6: Keep Thorough Records

Maintain copies of all documents related to the reportable transaction. The IRS may request additional information. Requirements for filing Form 8886 - Q&A

Common Mistakes and How to Avoid Them

Mistake #1: Incomplete Disclosures

The most common error is leaving sections blank or writing "information provided upon request." The IRS considers such forms incomplete, triggering penalties.
How to avoid: Complete every applicable line. If Line 7 asks for tax benefits, check the appropriate boxes and provide detailed descriptions. If you indicate participation through a related entity on Line 5a, you must complete Lines 5b and 5c with that entity's information.

Mistake #2: Missing the OTSA Filing

Many taxpayers attach Form 8886 to their return but forget to send the separate copy to OTSA for initial year filings.
How to avoid: Create a checklist. If this is the first year disclosing a transaction, sending to OTSA is mandatory—mark it on your calendar and get proof of mailing or faxing.

Mistake #3: Vague Transaction Descriptions

Providing high-level summaries without specific details, amounts, dates, and step-by-step explanations leaves your disclosure incomplete.
How to avoid: Pretend you're explaining the transaction to someone with no prior knowledge. Include dollar amounts, dates, descriptions of each step, relationships between parties, and the economic/business reasons for the structure.

Mistake #4: Assuming Someone Else Filed

Even if your partner, another investor, or an advisor filed Form 8886 for the same transaction, you still must file your own.
How to avoid: Never assume disclosure obligations are shared—they're individual. Everyone participating must file.

Mistake #5: Failing to Disclose Protective Filings Properly

Some taxpayers check the "protective disclosure" box thinking it excuses incomplete information. It doesn't.
How to avoid: Protective disclosures must be just as complete as regular disclosures. Check the box if you're unsure whether disclosure is required, but provide all requested information regardless.

Mistake #6: Missing Reclassification Deadlines

When the IRS adds a transaction to the "listed" or "transaction of interest" categories after you filed your return, strict deadlines apply.
How to avoid: Monitor IRS notices and announcements. If you participated in any transaction later classified as reportable, set a 90-day deadline reminder from the announcement date. Instructions for Form 8886 (Rev. August 2017)

What Happens After You File

Filing Form 8886 doesn't trigger an automatic audit, but it does alert the IRS to examine your transaction more closely. Here's what typically occurs:

Initial Processing

Your form goes to OTSA, where analysts review it for completeness and assess whether the transaction warrants further investigation. Complete, accurate filings may receive no follow-up if the IRS determines the transaction is legitimate.

Potential Information Requests

The IRS may contact you requesting additional documentation, explanations, or clarification about aspects of the transaction. Respond promptly and thoroughly to avoid complications.

Extended Assessment Period

For undisclosed listed transactions, the normal statute of limitations doesn't apply. The IRS has until one year after you properly disclose (or a material advisor provides required information) to assess additional taxes. This can leave years open indefinitely if you never file.

Penalty Considerations

Properly disclosing reportable transactions provides some protection. If you have a "reportable transaction understatement" (the IRS disallows your claimed tax benefits), the accuracy-related penalty under Section 6662A is 20% for disclosed transactions but increases to 30% for undisclosed ones. Proper disclosure may also support a "reasonable cause and good faith" defense against penalties.

No Change Scenarios

Many taxpayers file Form 8886, hear nothing further, and their tax returns are processed normally. Disclosure alone doesn't mean the IRS will challenge your tax treatment—it simply ensures they're aware of the transaction. Instructions for Form 8886 (Rev. August 2017)

FAQs

Q1: Does filing Form 8886 mean I did something wrong?

No. The form is simply a disclosure requirement. Many reportable transactions are perfectly legitimate tax planning strategies. The IRS wants visibility into certain transaction types to distinguish proper tax planning from abusive schemes. Filing doesn't equal guilt.

Q2: What are the penalties for not filing Form 8886?

Section 6707A imposes penalties for each failure to file, file completely, or file timely. Minimum penalties are $5,000 for individuals and $10,000 for other taxpayers per transaction. For listed transactions, maximums reach $100,000 (individuals) or $200,000 (others) annually. The penalty equals 75% of the tax reduction from the transaction if that's higher, subject to these maximums. For non-listed reportable transactions, annual maximums are lower: $10,000 for individuals and $50,000 for others.

Q3: If my partnership or S corporation files Form 8886, do I need to file individually?

It depends on your share of losses or benefits. The entity files based on entity-level thresholds, but you file based on your individual threshold. For example, if a partnership has a $12 million loss and you're allocated $2.4 million as an individual partner, the partnership files (exceeds $2 million partnership threshold) and you file (exceeds $2 million individual threshold), but a corporate partner with a $9.6 million share wouldn't file (below the $10 million corporate threshold).

Q4: What if I realize I should have filed Form 8886 with a prior year return?

File it as soon as possible. Submit Form 8886 with a cover letter to the IRS service center where you filed your original return, writing "Section 6501(c)(10) Disclosure" at the top if it's a previously undisclosed listed transaction. Include a penalty-of-perjury statement in your cover letter. Also send a copy to OTSA simultaneously. While late filing may still trigger penalties, prompt voluntary disclosure is better than waiting for the IRS to discover the omission.

Q5: Can I file Form 8886 electronically?

Yes, you can e-file Form 8886 attached to your electronic tax return. However, the separate copy required for OTSA on initial year filings must still be mailed or faxed (fax to 844-253-2553). The OTSA copy must be an exact duplicate of what you e-filed, showing the same information word-for-word.

Q6: How long do I need to keep records related to reportable transactions?

You must maintain all documents and records related to reportable transactions as long as they may be material to IRS administration of tax law—essentially indefinitely until the statute of limitations expires. For undisclosed listed transactions, that could be many years, so retain comprehensive documentation.

Q7: What's a "reportable transaction number" and do I need one?

A reportable transaction number (sometimes called a tax shelter registration number) is a 9-digit or 11-digit number (sometimes beginning with "MA") that material advisors must obtain and provide to participants in certain reportable transactions. If you received one from your advisor, you must include it on Line 1c of Form 8886. However, if you weren't provided a number, you can't create one—just leave that line blank and complete the rest of the form. Requirements for filing Form 8886 - Q&A
