1. What is a Tax Matters Partner (TMP)?#

The Tax Matters Partner is a legacy role created under the Tax Equity and Fiscal Responsibility Act (TEFRA) of 1982, designed to streamline IRS communications for partnership audits for tax years starting before January 1, 2018.

Key Eligibility Rules for TMPs#

A TMP must be a general partner of the partnership they represent: third-party tax professionals (e.g., CPAs, attorneys) cannot serve as TMPs, even if they handle the partnership’s regular tax filing.

Core Responsibilities of a TMP#

• Serve as the official liaison between the partnership and the IRS for TEFRA-era audits, information requests, and administrative appeals
• Notify all current and former partners of ongoing audit proceedings, proposed adjustments, and settlement offers
• Participate in audit negotiations and settlement discussions on behalf of the partnership
• File required administrative paperwork related to TEFRA audit outcomes

Critical Limitations of the TMP Role#

The TMP had very limited binding authority: they could only represent the partnership itself, not individual partners. Any partner could choose to opt out of a TMP-negotiated audit settlement, forcing the IRS to pursue each partner individually for unpaid tax liabilities. This inefficiency is the primary reason the TMP role was phased out for most partnerships in 2018. TMPs are only relevant today for:

• Partnerships with open tax years starting before 2018
• Partnerships that explicitly elected to retain TEFRA rules after 2017 (a rare choice)

2. What is a Partnership Representative (PR)?#

The Partnership Representative is the modern replacement for the TMP, created under the Bipartisan Budget Act (BBA) of 2015 for all tax years starting on or after January 1, 2018. The BBA overhauled partnership audit rules to simplify the IRS’s process for collecting unpaid tax from partnerships, and the PR role is central to this new regime.

Key Eligibility Rules for PRs#

Unlike TMPs, PRs do not need to be partners of the partnership. To qualify, a PR only needs:

• A valid U.S. tax identification number (TIN)
• Substantial physical presence in the United States This means partnerships can appoint third-party tax experts (CPAs, enrolled agents, tax attorneys) as their PR, which is a common choice for partners with limited tax expertise.

Core Responsibilities of a PR#

• Serve as the sole official point of contact for the IRS for all BBA-era audits, information requests, adjustments, and appeals
• Make binding decisions about audit settlements, payment plans, and adjustment allocations on behalf of the partnership
• Notify partners of audit outcomes and adjustments, as required by the partnership agreement
• File all required paperwork related to BBA audit proceedings, including adjustment elections and payment requests

Critical Authority of the PR Role#

The biggest difference between a PR and TMP is that a PR’s decisions bind all current and former partners of the partnership, with no individual opt-out rights. If a PR agrees to a $100,000 audit settlement, all partners are legally required to pay their share of that liability, even if they disagreed with the PR’s choice. The only exception is for partnerships that annually elect to opt out of the BBA regime entirely, which is only allowed for partnerships with 100 or fewer eligible partners (all partners must be individuals, estates, C-corps, or S-corps; no pass-through entities like other partnerships or trusts are allowed as partners for opt-out eligibility).

All U.S. partnerships are required to designate a PR on their annual Form 1065 filing. If no PR is designated, the IRS will appoint one on the partnership’s behalf, which often leads to higher costs and unfavorable outcomes for partners.

3. Core Side-by-Side Differences Between TMP and PR#

The table below summarizes the most important distinctions between the two roles:

The shift from TMP to PR was driven by IRS frustration with TEFRA-era inefficiencies: under TEFRA, the IRS often spent years pursuing individual partners for unpaid tax after audit adjustments, while the BBA shifts default liability to the partnership itself and centralizes decision-making with the PR to speed up audit resolution.

4. How to Select the Right Representative for Your Partnership#

Follow these best practices to avoid costly mistakes when appointing your tax representative:

1. Confirm if you need a TMP first: Only appoint a TMP if you have open pre-2018 tax years or retained TEFRA rules. For almost all modern partnerships, you only need to appoint a PR.
2. Prioritize tax expertise over internal status: Many partnerships appoint a third-party tax professional as PR instead of a partner with limited tax knowledge, as missteps during audits can lead to hundreds of thousands of dollars in unnecessary liability.
3. Verify U.S. eligibility: Your PR must have a physical U.S. address and valid U.S. TIN; foreign partners or overseas tax professionals cannot serve in this role.
4. Outline PR authority in your partnership agreement: To avoid disputes, explicitly specify what decisions require partner approval (e.g., settlements over $50,000 require a majority partner vote) before appointing a PR.
5. Consider BBA opt-out eligibility if applicable: If you have 100 or fewer eligible partners, you can choose to opt out of the BBA regime annually, which lets individual partners handle their own audit adjustments instead of being bound by the PR’s decisions. This is a good choice for small partnerships with transparent financials.

5. Frequently Asked Questions#

Q: Can a partnership have both a TMP and PR at the same time?#

A: Yes, but only if the partnership has open pre-2018 tax years. The TMP will handle TEFRA-era audits for those old years, while the PR will handle all post-2017 tax matters.

Q: What happens if we forget to designate a PR on our Form 1065?#

A: The IRS will appoint a PR for you, usually an unrelated third party who will charge the partnership for their services. You will have no control over their decisions, so it is always recommended to proactively designate a PR you trust.

Q: Can we remove a PR if we disagree with their decisions?#

A: You can file Form 8979 to revoke a PR’s appointment and designate a new representative at any time, but the revocation only applies to future proceedings. Any decisions the PR made before being removed remain binding on all partners.

Q: Is a managing member of an LLC taxed as a partnership automatically the PR?#

A: No. There are no automatic PR appointments: you must explicitly list your chosen PR on your annual Form 1065 filing for the designation to be valid.

6. Final Takeaways#

• The Tax Matters Partner is a legacy role that only applies to pre-2018 tax years, while the Partnership Representative is the mandatory official point of contact for all modern partnerships.
• The most impactful difference between the two roles is that PRs have the authority to bind all current and former partners to audit decisions, with no individual opt-out rights.
• Always prioritize expertise, trust, and U.S. eligibility when selecting a PR, and explicitly outline their decision-making authority in your partnership agreement to avoid disputes.
• If you are unsure about your eligibility for BBA opt-out or the right PR for your business, consult a licensed partnership tax professional.
