Case Summary

Crane v. Commissioner is a foundational tax case that explains how debt affects your tax basis in property. This case is essential for understanding real estate transactions, depreciation deductions, and calculating gain or loss when you sell property. The principle established here affects millions of property owners and real estate investors.

The Facts of the Case

Beulah Crane inherited an apartment building from her late husband in 1932. The property was worth approximately $262,000 but was subject to a mortgage of $262,000—meaning she inherited property with no equity.

Key Facts:Key Facts:

  • Property value: $262,000
  • Mortgage debt: $262,000
  • Net equity: $0
  • Mrs. Crane was not personally liable for the mortgage (non-recourse debt)

From 1932-1938, Mrs. Crane:

  • Collected rents from the property
  • Claimed depreciation deductions on her tax returns
  • Reported the full property value ($262,000) as her basis for depreciation

In 1938, she sold the property for $3,000 cash plus the buyer's assumption of the $262,000 mortgage.

The Tax Dispute

Mrs. Crane's Position:

  • Her basis was $0 (no equity inherited)
  • Therefore, she couldn't claim depreciation
  • Amount realized on sale: $3,000 (only the cash received)
  • Gain on sale: Minimal

The IRS's Position:

  • Her basis included the $262,000 mortgage
  • She properly claimed depreciation, reducing her basis
  • Amount realized includes the $262,000 debt relief
  • Gain on sale: Substantial

The Supreme Court's Landmark Decision

The Ruling: Debt Is Included in Basis

The Supreme Court ruled in favor of the IRS, establishing several crucial principles:

1. Debt-Financed Property Has Full Basis

When you acquire property subject to debt, your basis includes:

  • Cash or property you pay
  • PLUS the amount of debt (even if non-recourse)PLUS the amount of debt

Example:Example:

  • Buy property for $500,000
  • Pay $100,000 cash down
  • Finance $400,000 with mortgage
  • Your basis: $500,000 (not just $100,000)Your basis: $500,000

2. Amount Realized Includes Debt Relief

When you sell or dispose of property, your "amount realized" includes:

  • Cash or property received
  • PLUS debt you're relieved ofPLUS debt you're relieved of

Example:Example:

  • Sell property for $50,000 cash
  • Buyer assumes your $400,000 mortgage
  • Amount realized: $450,000 (not just $50,000)Amount realized: $450,000

3. Consistency Principle

The Court reasoned: If you include debt in basis (allowing larger depreciation deductions), you must also include debt relief in amount realized when you dispose of the property. You can't have it both ways.

Understanding Tax Basis With Debt

Why Basis Matters

Basis determines:

  1. Depreciation Deductions: Higher basis = larger annual deductionsDepreciation Deductions:
  2. Gain or Loss on Sale: Gain = Amount Realized minus Adjusted BasisGain or Loss on Sale:
  3. Tax Consequences: Lower basis = higher gain = more taxTax Consequences:

The Crane Formula

Initial Basis (Purchase) Cash paid $100,000 + Debt assumed/incurred $400,000 = Initial Basis $500,000Initial Basis (Purchase)Cash paid $100,000+ Debt assumed/incurred $400,000= Initial Basis $500,000
Initial Basis (Purchase)
Cash paid$100,000
+ Debt assumed/incurred$400,000
= Initial Basis= Initial Basis$500,000$500,000
Adjusted Basis (After Holding Period) Initial basis $500,000 - Depreciation taken ($100,000) + Capital improvements $50,000 = Adjusted Basis $450,000Adjusted Basis (After Holding Period)Initial basis $500,000- Depreciation taken ($100,000)+ Capital improvements $50,000= Adjusted Basis $450,000
Adjusted Basis (After Holding Period)
Initial basis$500,000
- Depreciation taken($100,000)
+ Capital improvements$50,000
= Adjusted Basis= Adjusted Basis$450,000$450,000
Gain or Loss on Sale Cash received $75,000 + Debt relief $400,000 = Amount Realized $475,000 - Adjusted Basis ($450,000) = Gain $25,000Gain or Loss on SaleCash received $75,000+ Debt relief $400,000= Amount Realized $475,000- Adjusted Basis ($450,000)= Gain $25,000
Gain or Loss on Sale
Cash received$75,000
+ Debt relief$400,000
= Amount Realized= Amount Realized$475,000$475,000
- Adjusted Basis($450,000)
= Gain= Gain$25,000$25,000

The Crane Principle and 1031 Exchanges

Debt Balancing in Like-Kind Exchanges

When doing a 1031 exchange, Crane principles affect whether you have fully tax-deferred gain:

Rule: Debt on new property must be equal to or greater than debt on old property (or you must add cash).Rule:

Example: Partial Taxable Exchange

  • Relinquished property: FMV $500,000, Mortgage $300,000Relinquished property:
  • Replacement property: FMV $500,000, Mortgage $200,000Replacement property:
  • Result: You're relieved of $100,000 more debt than you assumeResult:
  • Tax Consequence: $100,000 "boot" (taxable gain)Tax Consequence:

Solution: Add $100,000 cash to maintain equal or greater debt.Solution:

Recourse vs. Non-Recourse Debt

Non-Recourse Debt (Crane)

  • Definition: Lender can only foreclose on property; can't pursue you personallyDefinition:
  • Tax Treatment: Included in basis and amount realizedTax Treatment:
  • Common For: Commercial real estate, investment propertyCommon For:

Recourse Debt

  • Definition: You're personally liable; lender can pursue your other assetsDefinition:
  • Tax Treatment: Also included in basis and amount realizedTax Treatment:
  • Common For: Personal residences, most loansCommon For:

The Tufts Case Extension

In Commissioner v. Tufts (1983), the Supreme Court extended Crane, holding that debt relief is included in amount realized even if the debt exceeds the property's fair market value.even if the debt exceeds the property's fair market value.

Example:Example:

  • Property FMV: $500,000
  • Non-recourse debt: $600,000
  • You abandon the property in foreclosure
  • Amount realized: $600,000 (the full debt amount, not just $500,000)Amount realized: $600,000

Implications for Real Estate Investors

The Power of Leverage

Crane makes leveraged real estate investing tax-advantaged:

  1. Full Basis for Depreciation: Deduct depreciation on the full value, even though you only put down 20%Full Basis for Depreciation:
  2. Amplified Returns: Appreciation and depreciation apply to full value, not just your equityAmplified Returns:
  3. Tax Deferral: Depreciation creates tax losses that shelter other incomeTax Deferral:

Example: Leveraged Real Estate

  • Buy $1,000,000 building with $200,000 down payment
  • Depreciate $900,000 (building only) over 39 years = $23,077/year
  • Your actual cash invested: $200,000
  • Annual depreciation deduction: $23,077 (11.5% of your cash investment!)

Potential Traps and Pitfalls

Trap #1: Phantom Gain on Foreclosure

If you lose property to foreclosure, you can have taxable gain even though you lost money:

  • This happens when accumulated depreciation exceeds your equity
  • You still recognize gain equal to debt relief minus adjusted basis
  • May also have cancellation of debt income

Trap #2: Refinancing and Basis

Common misconception: Refinancing increases basis

WRONG: Refinancing doesn't change basis. Only acquisition debt and capital improvements increase basis.WRONG:

Trap #3: Debt Assumption in Sale

Sellers often forget that buyer's assumption of debt is part of amount realized:

  • Receive $50,000 cash
  • Think you only made $50,000
  • Actually realized $450,000 (including $400,000 debt relief)
  • Surprise: Large tax bill!

Special Situations

Principal Residence Exclusion

Good news: The $250,000/$500,000 home sale exclusion applies to gain calculated using Crane principles:

  • Your amount realized includes mortgage debt relief
  • But you can still exclude up to $250,000 (single) or $500,000 (married)
  • This protects most homeowners from tax on sale

Cancellation of Debt Income

If debt exceeds property value and lender forgives the excess:

  • You may have cancellation of debt (COD) income
  • This is separate from gain on disposition
  • Exceptions exist for insolvency, bankruptcy, qualified principal residence

Documentation and Record-Keeping

To properly apply Crane principles, maintain records of:

  • Purchase Price: Settlement statement showing price and debtPurchase Price:
  • Debt Amounts: Original mortgage and subsequent changesDebt Amounts:
  • Debt Paydown: Annual mortgage interest statementsDebt Paydown:
  • Capital Improvements: Receipts for improvements that increase basisCapital Improvements:
  • Depreciation: Annual depreciation schedulesDepreciation:
  • Sale Details: Settlement statement showing debt reliefSale Details:

Key Takeaways from Crane v. Commissioner

  1. Debt Is Part of Basis: Include mortgage debt when calculating initial basisDebt Is Part of Basis:
  2. Debt Relief Is Income: Include debt relief when calculating amount realized on saleDebt Relief Is Income:
  3. Consistency Required: If you get the benefit (depreciation), you must accept the burden (gain recognition)Consistency Required:
  4. Applies to All Debt: Both recourse and non-recourse debt follow these rulesApplies to All Debt:
  5. Track Everything: Maintain detailed records of debt and basis changesTrack Everything:

Anyone may arrange his affairs so that his taxes shall be as low as possible; he is not bound to choose that pattern which best pays the treasury. There is not even a patriotic duty to increase one's taxes. Over and over again the Courts have said that there is nothing sinister in so arranging affairs as to keep taxes as low as possible. Everyone does it, rich and poor alike and all do right, for nobody owes any public duty to pay more than the law demands.
