Introduction
"TEFRA AAR" trips up a lot of people. TEFRA governed older US partnership audit procedures, while most current partnership adjustments run through the BBA centralised partnership audit regime.
Mix the two up and you can file the wrong request, name the wrong representative, or tell partners the wrong thing.
This guide is for Australian businesses, investors and advisers with interests in US partnerships. It covers definitions, the legacy process, how TEFRA differs from BBA, and what it means for cross-border holders.
This article is general information only. Obtain year-specific tax advice from a qualified adviser before acting.
Key Takeaways
- TEFRA (Tax Equity and Fiscal Responsibility Act) partnership procedures mostly apply to legacy tax years.
- An AAR is a partnership-initiated request to adjust reported items, not an IRS examination.
- The TEFRA tax matters partner became the BBA partnership representative.
- Confirm the tax year, governing regime, current form instructions and deadlines first.
What Is a TEFRA AAR?
What TEFRA means in the partnership tax context
Congress passed TEFRA in 1982 (Pub. L. 97-248). The IRS described the unified procedures as a way to simplify audit, litigation and assessment by examining the partnership as an entity rather than each partner separately.
A TEFRA AAR was a request under former IRC section 6227 to adjust items reported on a partnership return. Rules depended on the tax year involved.
The purpose of an Administrative Adjustment Request
An AAR is its own statutory procedure. It is not:
- A simple amended return
- An IRS audit (TEFRA exams began with a Notice of Beginning of Administrative Proceeding)
- A Final Partnership Administrative Adjustment (FPAA) or notice of deficiency
- A partner's separate refund claim
Typical corrections involve income, deductions, credits, allocations or other partnership-level reporting errors. Confirm the exact historical scope under the law for the year in question.
Who could initiate a TEFRA AAR?
Only the tax matters partner (TMP), generally a designated general partner, could file for the partnership. A taxable partner could file a request for that partner's own items. By contrast, the BBA partnership representative has much broader authority to bind the partnership.
Before treating any filing as a TEFRA AAR, confirm the partnership was actually subject to TEFRA that year. Small partnerships (generally 10 or fewer eligible partners) were excluded. A nonresident alien individual was not an eligible partner for that test, and a pass-through partner generally defeated the exception.
Electing large partnerships had a separate regime.
Historical forms and supporting records
Form 8082 served as both a Notice of Inconsistent Treatment and an AAR. The TMP filed an entity-level AAR. A partner filed in duplicate: one copy with the partner's amended return, one to the service center.
Treat these steps as historical only. The October 2025 Form 8082 instructions dropped the TEFRA AAR boxes, so they are not current filing requirements.
When a TEFRA AAR may not be appropriate
The right remedy might instead be an amended or superseding return, a partner-level filing, or a BBA AAR. It depends on the entity, year, election status and error type. Establish the governing audit regime before preparing any form or notifying partners.
How the TEFRA AAR Process Worked
Step 1: Confirm the governing tax year and partnership status
Review the return, filing date, tax year, entity classification and TEFRA applicability. Check whether an examination was already underway.
Former section 6227 generally allowed an AAR within 3 years after the later of the return's filing date or due date. The request also had to be filed before the FPAA was mailed to the TMP. Do not confuse this window with the separate assessment period in former section 6229.
Step 2: Identify and document the proposed adjustment
Trace the error to the books, schedules, allocations, Schedule K-1 reporting and workpapers. Schedule K-1 shows each partner's share of income, deductions and credits, so a change here flows straight into partner returns.
Then map the effect on each partner's income, deductions, credits, basis, distributions and later returns.
Step 3: Prepare and submit the AAR
A TMP-filed AAR included revised schedules showing the effect on partners' distributive shares. It needed to identify the partnership, year, adjusted items and reasons. Check the Form 8082 instructions for that year covering signing authority, attachments and where to send it.
Step 4: Coordinate with partners and tax advisers
Partners may need notice and should review their own returns. Complications include:
- Tiered partnerships, where pass-through partners had forwarding duties (middle-tier pass-through returns are not AARs themselves)
- Former partners and transferred interests
- Foreign partners and those filing in several jurisdictions
Step 5: Track the IRS response and downstream filings
Keep proof of filing and watch for IRS correspondence. The IRS could assess a computational adjustment without deficiency procedures where no partner-level determination was needed. Reconcile the outcome and update partnership and partner records. Income increases, decreases and credit changes each drive different follow-up filings.
TEFRA AAR vs BBA AAR: Key Differences Today
Legislative transition and current relevance
BBA generally applies to partnership years beginning after 31 December 2017 unless the partnership validly elects out. Certain earlier years could elect in. TEFRA may still govern eligible legacy years. See the IRS BBA page to confirm the regime.
| Feature | TEFRA (legacy) | BBA (current) |
|---|---|---|
| Years | Generally pre-2018 | Generally beginning after 2017 |
| Contact | Tax matters partner | Partnership representative (and designated individual if an entity) |
| Deadline | 3 years, before FPAA | 3 years from filing or due date, before Notice of Administrative Proceeding |
| Tax result | Flowed to partners | Imputed underpayment, or push-out to reviewed-year partners |
Tax matters partner versus partnership representative
Under TEFRA, the tax matters partner was the main IRS contact, while partners kept more individual procedural rights. Under BBA, the partnership representative has sole authority, and the partnership and partners are bound by its actions.
It must meet substantial-presence rules: a US TIN, US street address and US phone number, plus availability to meet in the US. Review the partnership agreement separately for approval procedures and notification rights.
Where the adjustment is handled and who bears the tax
Under TEFRA, adjustments generally flowed through to partners’ own returns. Under BBA, the partnership computes any imputed underpayment and generally pays it, or elects at filing to push adjustments to reviewed-year partners.
Interest and penalties may apply. Partners can seek modifications, such as for tax-exempt partners, and treaty modification requests exist where treaty rules apply. Foreign status alone is not an exemption.
Forms and filing mechanics
For tax years beginning after 2024, Form 1065-X instructions say paper BBA AARs use Form 1065-X, while e-filers use Form 1065 with Form 8082. Forms 8985 and 8986 may be needed, and partners use Form 8978 for pushed-out adjustments. Verify names and dates against the IRS pages before filing.
Practical decision framework for readers
- Identify the tax year under review and its start date.
- Determine whether TEFRA or BBA applies, including any valid election out or in.
- Classify the correction as a partnership-item or other adjustment.
- Identify the authorised filing party (tax matters partner or partnership representative).
- Assess how partners will bear tax, interest and penalties.
- Confirm the correct IRS procedure and forms before filing.
An old return or a partnership-item correction alone is not a reason to use the TEFRA process.
Implications for Australian Businesses and Cross-Border Partnerships
US partnership interests and cross-border reporting
An Australian holder may need to align the adjustment with US filings, Schedule K-1 and K-3 reporting, accounting records and Australian tax advice. Under US rules, partnerships with effectively connected income allocable to foreign partners have withholding duties (Forms 8804, 8805 and 8813).
Treaty treatment, foreign tax credits, permanent establishment and Australian reporting depend on facts. Article 7 of the US-Australia treaty generally limits taxation of business profits to those attributable to a permanent establishment. Never assume treaty relief because an AAR exists.
For Australian reporting, the ATO says partners include their share of partnership net income whether or not cash was received. Foreign tax offsets may be available, with claims above A$1,000 needing an offset-limit calculation.
Records, ownership changes, and partner-level exposure
Preserve the documents you will need to support any adjustment:
- Partnership agreements and transfer documents
- Schedule K-1s, capital accounts and basis records
- Prior returns and IRS correspondence
The ATO generally requires relevant records for 5 years. Former partners, new partners, tiered entities and changed profit shares all complicate who bears an adjustment.
Governance and adviser coordination
Review agreements for:
- Audit notices and representative authority
- Indemnities and cooperation duties
- Responsibility for historic adjustments
US advisers, Australian advisers, accountants and the authorised representative should coordinate before anything is filed or any IRS notice is answered.

Frequently Asked Questions
What is an AAR for IRS?
An Administrative Adjustment Request is generally a partnership-initiated request to correct previously reported partnership tax items. The process depends on the tax year and governing audit regime.
What does TEFRA stand for?
Tax Equity and Fiscal Responsibility Act. Its 1982 partnership provisions created unified audit and adjustment procedures at the partnership level.
Is TEFRA still in effect?
Not as the general regime for partnership years beginning after 2017, where BBA generally applies. Older years and legacy proceedings may still need TEFRA analysis.
Who can file a TEFRA AAR?
Historically the tax matters partner filed for the partnership, and a partner could file for its own items. Verify authority, entity status, tax year and IRS procedures first.
What is the difference between a TEFRA AAR and a BBA AAR?
TEFRA used a tax matters partner and flowed adjustments to partners. BBA uses a partnership representative, an imputed underpayment or push-out election, and Form 1065-X or Form 8082 e-filing.
