Key Takeaways

  • Outside basis is adjusted annually for income, losses, distributions, and contributions.
  • The ordering rule: (1) income increases, (2) decreases for distributions, (3) decreases for losses.
  • Partnership liabilities increase partner basis—critical for loss deductions.
  • Recourse debt: allocated by economic risk of loss. Nonrecourse: by profit-sharing ratios.
  • Losses cannot reduce basis below zero; excess losses are suspended.
  • Tax-exempt income increases basis; nondeductible expenses decrease basis.

Partner's Basis Calculation

Why This Matters for the Exam

Partner basis is the most tested partnership topic. It determines loss deductibility, distribution taxation, and gain on sale. Master the ordering rules and debt allocation.

Expect at least 4-5 questions on basis calculations.

Annual Basis Adjustments

Partner's outside basis changes every year:

IncreasesDecreases
Additional contributionsDistributions received
Share of taxable incomeShare of losses
Share of tax-exempt incomeShare of nondeductible expenses
Increase in share of liabilitiesDecrease in share of liabilities

The Ordering Rules (Critical!)

The adjustments occur in this specific order:

OrderAdjustment
1Increase for income items
2Decrease for distributions
3Decrease for losses and deductions

Why Order Matters: Income is added first, which may allow larger tax-free distributions or more loss deductions.

Partnership Liabilities and Basis

A partner's share of partnership debt increases their outside basis:

Why This MattersEffect
Loss deductionsMore basis = deduct more losses
DistributionsMore basis = tax-free distributions
LeveragePartners get basis without contributing cash

Recourse vs. Nonrecourse Debt

Debt TypeAllocation Rule
RecoursePartner who bears economic risk of loss
NonrecourseProfit-sharing ratios (generally)
Qualified nonrecourseSpecial rules for real estate

Recourse Debt Example

ScenarioAllocation
Partnership borrows $100,000
Partner A guarantees the loan
Allocation100% to Partner A

Nonrecourse Debt Example

ScenarioAllocation
Partnership borrows $100,000 (nonrecourse)
Partner A: 40% profit interest
Partner B: 60% profit interest
Partner A share$40,000
Partner B share$60,000

Basis Adjustment Example

TransactionAmountRunning Basis
Beginning basis$50,000
+ Share of income$30,000$80,000
+ Tax-exempt interest$5,000$85,000
- Distribution($20,000)$65,000
- Share of loss($40,000)$25,000
Ending basis$25,000

Loss Limitation Example

ScenarioAmount
Partner basis$20,000
Share of partnership loss$35,000
Deductible loss$20,000
Suspended loss$15,000
Ending basis$0

Real-World Scenario

Scenario: Partner has $50,000 basis. Partnership allocates $30,000 income and $10,000 tax-exempt interest. Partner receives $25,000 distribution.

  • Step 1: Add income: $50,000 + $30,000 + $10,000 = $90,000.
  • Step 2: Subtract distribution: $90,000 - $25,000 = $65,000.
  • Ending basis: $65,000.

On the Exam

Expect 4-5 questions on basis, typically:

  1. Calculation Questions: "What is the partner's ending basis?"
  2. Loss Limit Questions: "How much loss can the partner deduct?"
  3. Debt Questions: "How is nonrecourse debt allocated?"
  4. Order Questions: "What is the order of basis adjustments?"

The key is to remember: Order: income → distributions → losses. Losses limited to basis. Recourse = economic risk. Nonrecourse = profit ratios.
