1. Introduction: What is Form 13751?

IRS Form 13751, officially titled the Waiver of Right to Consistent Agreement of Partnership Items and Partnership-Level Determinations as to Penalties, Additions to Tax, and Additional Amounts, is a specialized legal waiver published by the Internal Revenue Service (IRS). The IRS operates as a bureau of the United States Department of the Treasury, administering the federal tax code and enforcing tax shelter compliance.

Unlike personal tax returns or everyday deduction schedules, Form 13751 is an administrative legal agreement tied to partnership tax law. It was created in connection with IRS Announcement 2005-80, which established a historic settlement initiative for taxpayers who participated in abusive tax avoidance transactions.

Form 13751 was used specifically when a tax shelter was structured through a partnership governed by the Tax Equity and Fiscal Responsibility Act of 1982 (TEFRA). By executing this form, an individual partner formally gave up their statutory right to demand the same settlement terms offered to other partners, allowing them to settle their tax liabilities independently with the federal government.

2. Purpose of the Form

Under traditional TEFRA partnership audit rules in Internal Revenue Code Section 6224(c)(2), Congress created the “consistent settlement” rule. This rule required that if the IRS entered into a settlement agreement with any partner regarding partnership items, the agency was legally obligated to offer identical, consistent settlement terms to every other partner who requested it.

When the IRS launched its global settlement initiative under Announcement 2005-80 to resolve 21 promoted tax shelter schemes, this consistent agreement rule created a serious legal dilemma. The initiative offered reduced penalties and fee deductions to eligible investors, but strictly barred tax shelter promoters, brokers, and organizers from participating. If an eligible investor settled, an ineligible promoter who also held a partnership interest could theoretically argue that TEFRA law gave them a statutory right to the same favorable settlement.

Form 13751 exists to solve this problem. Under Internal Revenue Code Section 6224(b), partners are permitted to waive their statutory rights. Form 13751 serves as an explicit, irrevocable waiver where the settling partner forfeits the right to consistent settlement terms. This severed the settling partner’s case from the rest of the partnership, ensuring that ineligible promoters could not piggyback on the deal and settling taxpayers could not later demand different terms if non-settling partners received a court victory.

3. Who Needs to File This Form

Form 13751 was an essential companion document for taxpayers resolving promoted tax shelters. You needed to execute this form if you met the following criteria:

Participated in Announcement 2005-80: You elected to settle your tax shelter liabilities under the global settlement initiative using Form 13750.
Involved a TEFRA Partnership Entity: The tax avoidance transaction—such as a foreign currency option scheme, distressed asset trust, or straddle—was executed through or generated flow-through losses from a partnership subject to TEFRA rules.
Individual, Corporate, or Trust Partners: You were a direct or indirect partner who claimed partnership deductions, losses, or basis adjustments on your personal or corporate return.

Submitting Form 13751 was a mandatory condition precedent for partnership transactions. If an eligible partner refused to sign this waiver, the IRS would reject their settlement election on Form 13750.

4. Who Is Exempt / Not Required to File

Because Form 13751 applied exclusively to partnership-level tax shelter settlements under Announcement 2005-80, most taxpayers and entities were exempt from filing it:

Everyday Taxpayers: Individuals and small businesses resolving routine audits or filing annual tax returns never encounter this document.
Direct Individual Transactions: Taxpayers who entered into eligible tax shelter transactions directly in their own names without the use of a pass-through partnership entity.
Non-TEFRA Partnerships: Small partnerships that were exempt from TEFRA unified audit procedures under the small partnership exception.
Taxpayers Resolving Non-Shelter Audits: Partners settling ordinary business partnership examinations used standard settlement waivers, such as Form 870-P or Form 870-LT, rather than Form 13751.
Disqualified Promoters: Promoters, organizers, and material advisors who were legally barred from participating in the settlement initiative could not use this form.

5. When to File

Form 13751 operated under strict, coordinated deadlines linked directly to the primary settlement initiative:

Submission with Form 13750: Taxpayers typically submitted Form 13751 alongside Form 13750 prior to the initiative’s primary election cutoff on January 23, 2006.
Documentation Window: In cases where partnership relationships were clarified during initial review, the form was submitted during the subsequent 30-to-60-day documentation window.
Prior to Closing Agreement: Form 13751 had to be executed and verified before the IRS would finalize and sign the binding Form 906 Closing Agreement.

6. Where and How to File

Form 13751 was an administrative legal waiver that could not be submitted through consumer tax preparation software. It required physical submission to specialized IRS compliance teams.

Taxpayers were required to submit the signed original Form 13751 directly to the centralized IRS settlement processing unit in accordance with instructions outlined in Announcement 2005-80. In addition, if the partnership was under active examination or before the IRS Independent Office of Appeals, a copy was provided to the assigned revenue agent or appeals officer.

Submissions were delivered to the specific IRS address as per instructions on the settlement notice, typically via certified mail with a return receipt requested. This ensured documented proof that the partner complied with the statutory waiver requirements before the initiative deadline expired.

7. Step-by-Step Instructions to Fill the Form

Form 13751 is a single-page legal waiver. Every box must accurately match IRS partnership records to be legally effective. Review the table below for a line-by-line guide.

Understanding the Legal Effect of the Waiver

When you signed Form 13751, you entered into a permanent legal commitment regarding your partnership items:

No Future Consistency Claims: You agreed that if other partners in the same partnership later litigated their cases and won a favorable outcome in court, you could not demand that the IRS apply those court findings to your tax bill.
Finality of Terms: You agreed that your settlement under Announcement 2005-80 was final and independent of any other settlement agreements the IRS might enter into with other partners.
Covers Penalties and Interest: The waiver explicitly covers not only substantive tax items, but also partnership-level determinations regarding accuracy penalties and additions to tax.

8. Required Documents/Information Needed Before Filling

Before completing Form 13751, assemble the following records to ensure all identification numbers and tax periods match IRS files:

Form 13750: The primary election form confirming your participation in the Announcement 2005-80 settlement.
Schedule K-1 (Form 1065): The Partner’s Share of Income, Deductions, and Credits for each tax year in dispute, verifying the partnership’s legal name and EIN.
Individual Tax Returns: Copies of your Form 1040 or corporate Form 1120 showing where the partnership items were reported.
Partnership Agreement Documents: Organizational paperwork confirming your status as a direct or indirect partner during the relevant tax years.
Form 2848 (Power of Attorney): A valid authorization form if legal counsel or a CPA signed or prepared documents on your behalf.

9. Common Mistakes to Avoid

Because Form 13751 is a precise legal instrument, administrative errors could delay or invalidate a taxpayer’s settlement. Avoid these frequent mistakes:

Omitting Form 13751 from the Election: Submitting Form 13750 for a partnership tax shelter without including Form 13751 caused the IRS to reject the settlement election.
Mismatched Identification Numbers: Entering an incorrect partnership EIN or transposing digits on Box 4 prevented IRS computer systems from linking the waiver to the partnership master file.
Missing Spousal Signatures: If the partnership investment was held jointly or reported on a joint Form 1040, failing to have both spouses sign the waiver rendered it legally ineffective.
Expecting Future Adjustments: Assuming that signing the form still allowed you to benefit from other partners’ court battles was a serious misunderstanding; the waiver permanently severed your right to future consistent terms.
Submitting for Non-TEFRA Entities: Submitting Form 13751 for transactions conducted through single-member LLCs or non-partnership structures caused administrative confusion and processing delays.

10. Penalties for Non-Filing or Errors

Form 13751 was an elective legal waiver rather than a tax return, so there were no direct civil tax fines simply for choosing not to sign it. However, the legal and financial consequences of refusing to submit the form were severe:

Disqualification from Settlement: Refusing to execute Form 13751 resulted in immediate disqualification from the Announcement 2005-80 settlement initiative.
Maximum Statutory Penalties: Taxpayers who were disqualified faced the full 40% accuracy-related penalty for gross valuation misstatements or reportable transaction understatements under Section 6662A, rather than the reduced 5% to 20% rates.
Loss of Out-of-Pocket Fee Deductions: Taxpayers who did not settle were barred from claiming ordinary loss deductions for fees paid to shelter promoters and attorneys.
Continuous Compounding Interest: Taxpayers who bypassed the settlement lost interest relief protections under Section 303 of the Gulf Opportunity Zone (GO Zone) Act of 2005, facing mounting compounding interest charges.
Protracted Litigation: Non-settling partners remained subject to ongoing TEFRA partnership audits and litigation in the U.S. Tax Court, incurring heavy legal costs without guaranteed success.

12. Frequently Asked Questions

What does “consistent agreement” mean in partnership tax law?

Under former TEFRA rules in IRC Section 6224(c)(2), the consistent agreement rule required the IRS to offer any partner the same settlement terms that it had agreed to with any other partner in that partnership for that tax year. This ensured equal treatment among all partners in a unified audit.

Why did the IRS require Form 13751 under Announcement 2005-80?

The IRS required Form 13751 to prevent abusive shelter promoters from demanding the favorable settlement terms offered to investor partners, and to ensure that settling partners could not later reopen their cases if other partners achieved different results in court.

Can Form 13751 be used for modern partnership audits?

No. Form 13751 was designed specifically for TEFRA partnership settlements under Announcement 2005-80. In 2015, Congress replaced TEFRA with the Bipartisan Budget Act (BBA) centralized partnership audit regime, which eliminated the consistent settlement rule for modern partnership tax years.

What happened if another partner in my partnership won their case in court after I signed Form 13751?

By signing Form 13751, you explicitly waived your right to consistent terms. Even if another partner later won a complete victory in the U.S. Tax Court, your settlement under Announcement 2005-80 remained legally binding and could not be adjusted.

Did both spouses have to sign Form 13751?

Yes. If the partnership items were reported on a joint Form 1040 return, or if the partnership interest was held jointly by both spouses, federal regulations required both spouses to sign and date Form 13751.

How did Form 13751 protect the settling taxpayer?

While Form 13751 involved waiving a statutory right, it protected the settling taxpayer by allowing them to finalize their individual tax liability through a binding Form 906 closing agreement, isolating them from the ongoing audits and legal liabilities of non-settling partners.

13. Conclusion: Key Takeaways Summarized
