IRS Form 8986 Guide: Partner Push-Out Audit Adjustments

Introduction – What Is Form 8986?

IRS Form 8986, titled Partner’s Share of Adjustment(s) to Partnership-Related Item(s) (Required Under Sections 6226 and 6227), is a critical tax information return administered by the Internal Revenue Service (IRS) and the U.S. Department of the Treasury. It operates under the centralized partnership audit regime established by the Bipartisan Budget Act of 2015 (BBA).

In simple terms, Form 8986 functions as an amended Schedule K-1 following an IRS audit or a partnership correction. When an audited partnership elects to “push out” audit adjustments rather than paying the resulting tax bill at the partnership entity level, it issues Form 8986 to its partners to report each partner’s specific share of the adjustments.

Purpose of the Form – Why Does Form 8986 Exist?

Under default BBA audit rules, when the IRS audits a partnership and proposes changes, the partnership itself is required to pay an “imputed underpayment” (a collective tax assessment) calculated at the highest statutory tax rate (typically 37 percent). This entity-level payment can be unfair to current partners, as they might end up paying for tax errors that occurred years earlier under former owners.

Internal Revenue Code Section 6226 solves this issue by offering a push-out election. By making this election, the partnership shifts the tax liability to the partners who actually owned the business during the audited year (the “reviewed year”). Form 8986 is the legal vehicle that makes this possible: it breaks down each partner’s share of income, deduction, and credit adjustments, allowing partners to calculate and pay their own tax without forcing them to file amended tax returns for past years.

Who Needs to File This Form?

Form 8986 is generated and issued by business entities rather than individual taxpayers. You must prepare and file Form 8986 if your organization falls into one of the following categories:

• Audited BBA Partnerships: A partnership that underwent an IRS examination, received a Notice of Final Partnership Adjustment (FPA), and elected to push out adjustments under Section 6226.
• BBA AAR Partnerships: A partnership that files an Administrative Adjustment Request (AAR) under Section 6227 and pushes out adjustments to its partners.
• Pass-Through Partners Pushing Out: An upper-tier partnership, S corporation, trust, or estate that received a Form 8986 from a lower-tier entity and chooses to push the adjustments further out to its own partners or shareholders.

The issuing entity must submit copies of all issued Forms 8986 to the IRS (attached to master transmittal Form 8985) and furnish an individual copy to each affected partner.

Who Is Exempt / Not Required to File?

Many businesses and taxpayers will never need to prepare or issue Form 8986. You are exempt or not required to create this form if:

• Partnership Paid the Tax: The audited partnership chose to pay the imputed underpayment at the entity level rather than making a push-out election.
• BBA Opt-Out Partnerships: Small partnerships with 100 or fewer qualifying partners that made a valid election under Section 6221(b) to opt out of the centralized BBA audit rules.
• Pass-Through Partners Paying at Entity Level: An upper-tier pass-through entity that receives Form 8986 and elects to pay the tax liability at the entity level using Form 8985 and Form 8985-V rather than pushing it down further.
• Individual Partners: Individual investors and partners never prepare or file Form 8986. They receive Form 8986 and use the information to prepare Form 8978 on their own tax return.

When to File Form 8986

Form 8986 is an event-driven tax statement with strict, non-negotiable statutory deadlines:

• Audited Partnerships: Must file copies with the IRS and furnish copies to all partners no later than 60 calendar days after the date the IRS mails the Notice of Final Partnership Adjustment (FPA).
• AAR Partnerships: Must file with the IRS and furnish to partners concurrently with the filing of their Administrative Adjustment Request.
• Pass-Through Partners: Must file with the IRS and furnish to their own partners by the extended due date of the return for the partnership’s “adjustment year” (the tax year in which the lower-tier Form 8986 was received).

Where and How to File

Filing Form 8986 involves two separate delivery actions: transmitting records to the federal government and delivering statements to investors.

• Filing with the IRS: The partnership must submit Form 8986 electronically, accompanied by master transmittal Form 8985, through the dedicated IRS BBA partnership digital portal or as instructed by the IRS examination team.
• Furnishing to Partners: The partnership must deliver each partner’s specific Form 8986 via certified mail, hand delivery, or secure electronic portal transmission (provided the partner has consented to electronic delivery).

Step-by-Step Instructions to Fill Form 8986

Form 8986 consists of tracking identifiers, entity profiles, and an itemized adjustment schedule that mirrors Schedule K-1 line items.

Tracking Number and Header

Enter the unique Tracking Number assigned to the push-out batch. Identify the reviewed tax year (the year audited), and indicate whether the statement is issued by the original audited partnership or an intermediate pass-through partner.

Part-by-Part Line Breakdown

Part & Section	Form Focus	Filing Directions
Part I	Audited / AAR Partnership	Enter the legal name, Employer Identification Number (EIN), business address, and audit control number of the partnership that was originally audited.
Part II	Pass-Through Partner	Complete Part II only if the form is being issued by an intermediate pass-through entity (such as an upper-tier partnership or S corporation) pushing adjustments to its own owners.
Part III	Partner Information	Report the recipient partner’s full legal name, Taxpayer Identification Number (SSN or EIN), mailing address, partner entity type, and reviewed-year profit or loss percentage.
Part IV	Schedule of Adjustments	List each adjustment by Schedule K-1/K-3 line number, title, and code. Report the amount originally filed, the net audit adjustment, the recomputed amount, and the tax character (e.g., passive vs. nonpassive).
Part V	Penalties & Additions to Tax	Report any applicable penalties determined at the partnership level that are allocable to this specific partner.

Required Documents and Information Needed Before Filling

Before preparing Forms 8986 for your investors, assemble the following compliance records:

• Notice of Final Partnership Adjustment (FPA): The official IRS determination letter showing the finalized audit adjustments and establishing the 60-day push-out deadline.
• Master Form 8985: The transmittal summary that reconciles total partnership adjustments against the individual allocations on all Forms 8986.
• Reviewed-Year Tax Return: Filed copies of Form 1065 (including Schedule K and original Schedules K-1/K-3) for the audited year.
• Partner Census Records: Verified legal names, current mailing addresses, and Taxpayer Identification Numbers for all partners who owned interests during the reviewed year.

Common Mistakes to Avoid

Errors on Form 8986 can invalidate a push-out election, exposing the partnership to unexpected tax liabilities. Watch out for these frequent mistakes:

• Missing the 60-Day Deadline: Failing to furnish Forms 8986 to partners within 60 days of the FPA mailing date. Missing this deadline legally invalidates the push-out election, forcing the partnership to pay the entire tax bill at the top 37 percent rate.
• Omitting Form 8985: Sending Forms 8986 to the IRS without the mandatory master transmittal Form 8985. The IRS will reject unlinked submissions.
• Mismatched Allocations: The sum of all adjustments reported across every partner’s Form 8986 must reconcile perfectly with the total adjustments reported on master Form 8985.
• Recipient Filing an Amended Return: A partner who receives Form 8986 attempting to file an amended return (Form 1040-X). The partner must report the adjustments on Form 8978 on their current-year return.
• Transposing Tracking Numbers: Entering an incorrect or incomplete Tracking Number in the header, preventing the IRS automated system from linking the partner statement to the audit case.

Penalties for Non-Filing or Errors

Failing to properly execute and distribute Form 8986 carries catastrophic financial and legal consequences for the partnership:

• Automatic Invalidation of Push-Out: If Forms 8986 are not issued and filed on time, the push-out election is voided. The partnership immediately becomes liable for the full imputed underpayment at the maximum 37 percent rate, plus penalties and interest.
• Payee Statement Penalties (IRC Section 6722): The IRS assesses fines ranging from $60 to over $330 per missing or incorrect partner statement, with no maximum limit for intentional disregard.
• Information Return Penalties (IRC Section 6721): An identical, separate penalty applies for failing to submit electronic copies of Form 8986 to the IRS.
• Elevated Section 6621 Interest: Push-out adjustments carry an elevated statutory interest rate that is two percentage points higher than standard tax underpayment interest.

Related Forms and Schedules

Frequently Asked Questions

What should an individual partner do upon receiving Form 8986?

An individual partner must complete Form 8978 and its Schedule A, attaching both to their federal income tax return (Form 1040) for the tax year in which the Form 8986 was received. Form 8978 calculates the additional tax and interest owed.

Do I need to file an amended return (Form 1040-X) when I receive Form 8986?

No. Under the BBA centralized audit rules, you do not file an amended return for the past year that was audited. Instead, you calculate the tax impact on Form 8978 and pay the balance on your current-year tax return.

What must a pass-through entity do upon receiving Form 8986?

An upper-tier partnership or S corporation that receives Form 8986 must choose either to pay the tax at the entity level (submitting Form 8985 and Form 8985-V) or push the adjustments further out to its own partners by issuing new Forms 8986 accompanied by Form 8985.

What is the “Tracking Number” on Form 8986?

The Tracking Number is a unique alphanumeric identifier assigned by the partnership or pass-through entity. It links each individual partner’s Form 8986 to the master transmittal Form 8985 filed with the IRS.

Can a partner dispute the adjustments reported on Form 8986?

Generally, no. Under the BBA framework, all substantive tax disputes must be resolved during the audit by the designated Partnership Representative. Individual partners are legally bound by the partnership’s audit outcome.

Why does Part V include penalties?

If the IRS assessed penalties at the partnership level during the audit (such as a 20 percent accuracy-related penalty for negligence), those penalties are allocated to the partners on Part V and must be paid when the partner files Form 8978.

Conclusion – Key Takeaways Summarized

IRS Form 8986 is the indispensable communication document that allows BBA partnerships to push audit adjustments down to their partners. It replaces the complex process of amending past tax returns by giving each partner an itemized statement of adjustments to report on their current-year filing.

To protect your partnership from losing its push-out election, adhere strictly to the 60-day post-FPA deadline, reconcile all partner allocations against master Form 8985, transmit electronic records to the IRS, and ensure every partner receives their copy promptly to avoid severe statutory penalties.
