5.2 Basis, At-Risk (§465) & Passive Loss (§469) Limitations
Key Takeaways
Partnership losses reported on Schedule K-1 must pass through three successive statutory hurdle gates in strict order: (1) Outside Basis (§704(d)), (2) At-Risk Rules (§465), and (3) Passive Activity Loss rules (§469).
Under IRC §704(d), losses exceeding outside basis are suspended indefinitely and carry forward to subsequent years, preserving their tax character until basis is restored by income, contributions, or debt increases.
When a partner has multiple categories of losses and deductions exceeding available basis, the allowable basis is allocated pro-rata across all loss categories based on their relative amounts.
The at-risk rules of IRC §465 disallow losses funded by standard nonrecourse debt; however, Qualified Nonrecourse Financing (QNF) under §465(b)(6) for real estate holding activities increases both outside basis and at-risk basis.
Upon a fully taxable disposition of a partner's entire interest in a passive activity to an unrelated party under IRC §469(g), all suspended passive losses from that activity are freed and deductible against nonpassive income.
Basis, At-Risk (§465) & Passive Loss (§469) Limitations
When a partnership generates a net operating loss or capital loss, the conduit principle dictates that the loss passes through to the partners on Schedule K-1 (Form 1065). However, a partner cannot simply deduct that loss on their individual Form 1040.
Congress enacted a rigorous three-hurdle loss limitation framework to prevent tax avoidance and curb passive tax shelters. To be deductible against other income, every dollar of partnership loss must clear three successive statutory hurdle gates in strict chronological order. A loss stopped at Hurdle 1 never reaches Hurdle 2; a loss stopped at Hurdle 2 never reaches Hurdle 3.
The Three Sequential Loss Hurdle Gates
├── Hurdle 1: Outside Basis Limitation (IRC §704(d))
│ └── If basis is insufficient, excess is suspended indefinitely under §704(d)
├── Hurdle 2: At-Risk Limitation (IRC §465)
│ └── If at-risk amount is insufficient, excess is suspended indefinitely under §465 (Form 6198)
└── Hurdle 3: Passive Activity Loss Limitation (IRC §469)
└── If passive without passive income, suspended indefinitely under §469 (Form 8582)
Hurdle 1: The Outside Basis Limitation (IRC §704(d))
The first gate is the partner's adjusted outside basis under IRC §704(d). A partner's distributive share of partnership loss is allowed only to the extent of their adjusted outside basis at the end of the partnership tax year, determined after accounting for all positive income adjustments, distributions, and nondeductible expenditures.
Pro-Rata Allocation Among Multiple Loss Items
If a partner is allocated multiple categories of losses and deductions (e.g., ordinary business loss, net short-term capital loss, net long-term capital loss, Section 1231 loss, charitable contributions) and their total exceeds available outside basis, the allowable basis must be allocated pro-rata among all loss items based on their relative size (Treas. Reg. §1.704-1(d)(2)).
Worked Pro-Rata Example: Elena has an outside basis of $10,000 after positive adjustments and distributions. Her Schedule K-1 reports:
- Ordinary business loss: $15,000 (75% of total losses)
- Long-term capital loss: $5,000 (25% of total losses)
- Total losses: $20,000
Because total losses ($20,000) exceed available basis ($10,000), Elena must prorate her allowable loss:
- Allowable Ordinary Loss: $10,000 × ($15,000 / $20,000) = $7,500
- Allowable Capital Loss: $10,000 × ($5,000 / $20,000) = $2,500
- Suspended Ordinary Loss under §704(d): $15,000 - $7,500 = $7,500
- Suspended Capital Loss under §704(d): $5,000 - $2,500 = $2,500
- Ending Outside Basis: $0
Carryforward Rules under §704(d)
Disallowed losses are suspended under §704(d) indefinitely. They carry forward to subsequent tax years, retain their specific tax character, and are treated as incurred in the following year. The suspended losses are restored when outside basis is replenished by future partnership income, additional cash or property contributions, or net increases in partnership liabilities under §752(a).
Hurdle 2: The At-Risk Limitation (IRC §465)
Losses that successfully pass through Hurdle 1 next encounter IRC §465, enacted by the Tax Reform Act of 1976. The at-risk rules ensure that a partner can only deduct losses to the extent they are economically exposed to actual financial loss.
Calculating the At-Risk Amount
Under IRC §465(b), a partner's at-risk amount includes:
- Cash contributed to the partnership;
- The adjusted tax basis of property contributed to the partnership;
- Recourse liabilities of the partnership for which the partner bears personal liability (economic risk of loss);
- The net fair market value of personal assets pledged as collateral for partnership debt (provided the assets are not used in the partnership activity); and
- Qualified Nonrecourse Financing (QNF) under IRC §465(b)(6).
Items Excluded from the At-Risk Amount
- Standard Nonrecourse Liabilities: Commercial nonrecourse debt secured by equipment, inventory, or receivables increases outside basis under §752, but provides $0 at-risk basis because the partner has no personal liability.
- Stop-Loss Agreements and Guarantees: Amounts protected against loss through nonrecourse financing, guarantees, stop-loss agreements, or other similar arrangements (§465(b)(4)).
- Related-Party Debt: Amounts borrowed from a person who has an interest in the activity other than as a creditor (§465(b)(3)).
The Real Estate Exception: Qualified Nonrecourse Financing (QNF)
Under IRC §465(b)(6), nonrecourse debt is treated as an amount at risk only if it is Qualified Nonrecourse Financing. QNF must satisfy five strict statutory criteria:
- Borrowed with respect to the activity of holding real property;
- Borrowed from a qualified person (an entity actively and regularly engaged in the business of lending money, such as a bank or credit union) or a federal/state/local government;
- The lender is not the seller of the real property (seller financing cannot be QNF);
- The lender does not receive a fee with respect to the investment (promoter/syndicator fees disqualified);
- No person is personally liable for repayment, and the debt is not convertible into equity.
Form 6198 and Carryforward
Losses disallowed by the at-risk rules are suspended indefinitely under IRC §465(a)(2). Taxpayers compute at-risk limitations on Form 6198, At-Risk Limitations. When at-risk basis is restored in future years (via profits, cash contributions, or recourse debt), the suspended at-risk losses are released and advance to Hurdle 3.
Hurdle 3: The Passive Activity Loss Rules (IRC §469)
Losses that clear both Outside Basis (§704(d)) and At-Risk (§465) face the third gate: IRC §469, enacted by the Tax Reform Act of 1986. The passive activity loss (PAL) rules segregate income and losses into three distinct statutory "buckets":
- Active Income: Wages, salaries, tips, guaranteed payments for services, and profit from businesses in which the taxpayer materially participates.
- Portfolio Income: Interest, dividends, royalties, annuities, and capital gains from the sale of investment assets (stocks, bonds).
- Passive Income: Income from trade or business activities in which the taxpayer does not materially participate, plus all rental activities.
[!CRITICAL] The Core PAL Restriction: Passive activity losses can only offset passive activity income. They cannot offset active income (wages) or portfolio income (dividends, interest). Unused passive losses are suspended and carried forward indefinitely under IRC §469(b).
Material Participation Standards (Treas. Reg. §1.469-5T)
A partner's participation in an activity is "material" only if they are involved in operations on a regular, continuous, and substantial basis. The regulations establish seven alternative tests; meeting any one test establishes material participation:
- 500-Hour Test: The individual participates in the activity for more than 500 hours during the tax year.
- Substantially All Participation Test: The individual's participation constitutes substantially all of the participation of all individuals (including non-owners and employees).
- 100 Hours and Not Less Than Anyone Else: The individual participates for more than 100 hours, and their participation is not less than the participation of any other individual.
- Significant Participation Activity (SPA) Aggregate: The activity is an SPA (participation exceeds 100 hours), and the individual's aggregate participation in all SPAs during the year exceeds 500 hours.
- 5 of Prior 10 Years Test: The individual materially participated in the activity for any 5 taxable years (consecutive or nonconsecutive) during the 10 taxable years immediately preceding the tax year.
- Personal Service Activity Test: For personal service activities (health, law, engineering, architecture, accounting, actuarial science, performing arts, consulting), the individual materially participated for any 3 taxable years preceding the tax year.
- Facts and Circumstances Test: Based on all facts and circumstances, the individual participates on a regular, continuous, and substantial basis (requires at least 100 hours of participation).
Limited Partners Presumption (IRC §469(h)(2))
Under the Internal Revenue Code, limited partners are statutory presumed to be passive investors. A limited partner cannot establish material participation under tests 2, 3, 4, or 7. A limited partner can only be treated as materially participating if they satisfy:
- Test 1 (> 500 hours);
- Test 5 (5 of prior 10 years); or
- Test 6 (3 prior years for personal service activities).
Complete Disposition of Entire Interest (IRC §469(g))
Under IRC §469(g), when a taxpayer disposes of their entire interest in a passive activity in a fully taxable transaction to an unrelated party:
- All current and accumulated suspended passive activity losses from that specific activity are fully unlocked.
- The released suspended PALs are deducted in the following statutory hierarchy:
- First, against net income or gain from the disposed passive activity for the year (including gain recognized on the sale);
- Second, against net income or gain from all other passive activities;
- Finally, as an ordinary, nonpassive deduction against active income (wages) and portfolio income.
Warning
Transfers to related parties (under IRC §267(b) or §707(b)(1)), gifts, or tax-free Section 721/351 exchanges do not trigger the release of suspended passive losses under §469(g). Suspended losses remain with the transferor or are added to the basis of the gifted interest under §469(j)(6).

Comprehensive Worked Multi-Hurdle Scenario
Exam Scenario: Lucas is a 20% limited partner in the Titan Manufacturing Partnership. For tax year 2025, Lucas receives a Schedule K-1 reporting an ordinary business loss of ($50,000). Lucas has $120,000 of W-2 wage income and $0 passive income from other sources.
Financial Position at Dec 31, 2025:
- Capital contributed (cash): $15,000
- Lucas's share of recourse debt: $0 (limited partner, no guarantee)
- Lucas's share of commercial bank nonrecourse equipment debt: $25,000
- Lucas participated for 40 hours during 2025
Step-by-Step Gate Analysis:
- Hurdle 1 — Outside Basis (§704(d)):
- Outside basis = $15,000 cash + $25,000 nonrecourse debt = $40,000.
- Loss tested: $50,000.
- Allowable through Gate 1: $40,000.
- Suspended under §704(d): $50,000 - $40,000 = $10,000.
- Outside basis is reduced to $0.
- Hurdle 2 — At-Risk Limitation (§465):
- Loss arriving at Gate 2: $40,000.
- At-risk amount = $15,000 cash contributed + $0 recourse debt + $0 nonrecourse debt (equipment debt is NOT Qualified Nonrecourse Financing) = $15,000.
- Allowable through Gate 2: $15,000.
- Suspended under §465: $40,000 - $15,000 = $25,000 (reported on Form 6198).
- Hurdle 3 — Passive Activity Loss Limitation (§469):
- Loss arriving at Gate 3: $15,000.
- Participation: Lucas is a limited partner who worked only 40 hours. He fails all 7 material participation tests. The activity is passive.
- Passive income available: $0.
- Allowable deduction on 2025 Form 1040: $0.
- Suspended under §469: $15,000 (reported on Form 8582).
Final Result for 2025:
- Currently deductible loss on Form 1040: $0
- Suspended under §704(d) (outside basis): $10,000
- Suspended under §465 (at-risk): $25,000
- Suspended under §469 (passive loss): $15,000
- Total suspended losses: $50,000
An investor contributes $20,000 cash to a commercial equipment leasing partnership for a 20% limited partnership interest. The partnership borrows $100,000 on a commercial nonrecourse basis from a bank to purchase machinery, allocating $20,000 of the debt to the investor. During 2025, the investor's distributive share of ordinary partnership loss is $35,000. The investor has no passive income and did not participate in the operations. How is the $35,000 loss treated on the investor's 2025 tax return?
$20,000 is deductible against active income; $15,000 is suspended under Section 704(d).
$35,000 is fully deductible because total outside basis is $40,000.
$0 is currently deductible; $15,000 is suspended under Section 465, and $20,000 is suspended under Section 704(d).
$0 is currently deductible; $20,000 is suspended under Section 469, and $15,000 is suspended under Section 465.
A partner with an adjusted outside basis of $12,000 at year-end (after all income and distributions) receives a Schedule K-1 reporting a $12,000 ordinary business loss and a $6,000 net long-term capital loss. Under Treasury Regulation §1.704-1(d)(2), what amounts of ordinary loss and capital loss may the partner deduct for the current tax year?
$12,000 ordinary loss allowed; $0 capital loss allowed ($6,000 capital loss suspended).
$6,000 ordinary loss allowed; $6,000 capital loss allowed ($6,000 ordinary loss suspended).
$8,000 ordinary loss allowed; $4,000 capital loss allowed ($4,000 ordinary loss and $2,000 capital loss suspended).
$0 allowed; both losses are suspended until basis equals the total combined loss of $18,000.
In 2021, an individual acquired a limited partnership interest that generated $30,000 in passive activity losses, all of which were suspended under IRC §469. In October 2025, the individual sells their entire partnership interest to an unrelated third party in a fully taxable transaction, recognizing a $5,000 capital gain on the sale. The individual has $100,000 in salary income and no other passive income. What is the tax treatment of the $30,000 suspended passive loss in 2025?
$5,000 offsets the capital gain from the sale, and the remaining $25,000 is deductible as an ordinary nonpassive loss against salary income.
The entire $30,000 suspended loss is permanently forfeited upon the sale of the partnership interest.
Only $5,000 is allowed to offset the capital gain; the remaining $25,000 remains suspended until the taxpayer acquires a new passive activity.
The $30,000 loss is treated as a long-term capital loss deductible up to the $5,000 gain plus $3,000 against ordinary income.
