7.2 Basis of Gifted Property (Dual Basis Rule) & Inherited Property (Stepped-Up Basis)

Gifted Property Basis Architecture: IRC §1015

When a taxpayer transfers property as an inter vivos gift (a lifetime gift), the recipient (donee) pays no federal income tax on the receipt of the gift under IRC §102(a). However, the donee must establish an income tax basis in the property to calculate depreciation, gain, or loss upon future disposition under IRC §1015.

The calculation of gifted property basis depends upon a single fundamental threshold comparison made on the exact date of the gift: $\text{Fair Market Value (FMV) on Date of Gift vs. Donor's Adjusted Tax Basis}$

Scenario 1: FMV Equals or Exceeds Donor's Adjusted Basis (Appreciated Property)

When the fair market value of the property on the gift date is greater than or equal to the donor's adjusted basis, the rules are straightforward:

• Carryover Basis: The donee's adjusted basis is identical to the donor's adjusted basis at the time of the gift (often called "rollover basis").
• Holding Period Tacking: Under IRC §1223(2), the donor's holding period tacks onto the donee's holding period. If the donor held the property for 5 years, the donee is immediately deemed to have held the property for 5 years.

Gift Tax Adjustment for Net Appreciation (IRC §1015(d)(6))

If the donor actually pays federal gift tax on the transfer (Form 709), the donee is permitted to increase their carryover basis by the portion of the gift tax attributable to the net appreciation in the property:

$\text{Basis Increase} = \text{Federal Gift Tax Paid} \times \left( \frac{\text{FMV at Date of Gift} - \text{Donor's Adjusted Basis}}{\text{Amount of Taxable Gift}} \right)$

• Taxable Gift Amount: Generally equals FMV minus the annual gift tax exclusion ($19,000 for 2025).
• Basis Ceiling: In no event can this statutory gift tax adjustment increase the property's adjusted basis above its fair market value on the date of the gift.

Scenario 2: FMV is Less Than Donor's Adjusted Basis (The Dual Basis Rule)

To prevent wealthy taxpayers from transferring unrealized capital losses to family members in higher tax brackets, Congress enacted the Dual Basis Rule under IRC §1015(a). When property has declined in value prior to the gift (FMV < Donor's adjusted basis), the donee does not have a single basis; instead, the donee receives two separate bases until disposition:

1. Gain Basis (Donor's Adjusted Basis): Used to determine if the donee realizes a gain upon sale. The donor's holding period tacks onto the donee's holding period.
2. Loss Basis (FMV on Date of Gift): Used to determine if the donee realizes a loss upon sale. Under IRC §1223, the holding period does NOT tack; the donee's holding period begins on the day after the gift.
3. The "No Gain / No Loss" Zone: If the donee sells the property for an amount that is less than or equal to the gain basis, but greater than or equal to the loss basis, the taxpayer recognizes neither a taxable gain nor a deductible loss ($0 gain / $0 loss).

Three Concrete Dispositions Under the Dual Basis Rule

Fact Pattern: An aunt purchased corporate stock for $25,000. Several years later, when the stock's FMV had dropped to $15,000, she gifted the stock to her nephew. No gift tax was paid.

• Gain Basis: $25,000 (Holding period includes aunt's holding period)

• Loss Basis: $15,000 (Holding period begins day after gift)

• Disposition Case A (Sold Above Gain Basis): Nephew sells the stock for $28,000.

  • Using Gain Basis: $28,000 proceeds - $25,000 gain basis = $3,000 Capital Gain.
  • Holding period tacks from aunt (long-term).

• Disposition Case B (Sold Below Loss Basis): Nephew sells the stock for $11,000.

  • Using Loss Basis: $11,000 proceeds - $15,000 loss basis = $4,000 Capital Loss.
  • Holding period begins day after the gift (short-term if sold within one year of gift).

• Disposition Case C (Sold Within the Zone): Nephew sells the stock for $20,000.

  • Test for Gain: $20,000 proceeds - $25,000 gain basis = ($5,000) (No gain).
  • Test for Loss: $20,000 proceeds - $15,000 loss basis = +$5,000 (No loss).
  • Result: The nephew recognizes $0 Gain and $0 Loss on Form 8949.

Depreciation on Dual Basis Property: If depreciable property subject to the dual basis rule is converted to business or rental use, the donee must calculate annual depreciation deductions using the loss basis (FMV on date of gift).

Inherited Property Rules: IRC §1014 Stepped-Up Basis

Property acquired from a decedent is governed by IRC §1014. Instead of carrying over the prior owner's cost basis, the general rule is that property receives a new basis equal to its Fair Market Value (FMV) on the date of the decedent's death.

• Stepped-Up Basis: If the property appreciated during the decedent's lifetime, its basis is "stepped up" to date-of-death FMV. All unrealized appreciation that accumulated during the decedent's life escapes federal income taxation completely.
• Stepped-Down Basis: If the property declined in value during the decedent's lifetime, its basis is "stepped down" to date-of-death FMV. The decedent's unrealized economic loss is permanently extinguished and can never be deducted by either the estate or the beneficiary.

Automatic Long-Term Holding Period Rule (IRC §1223(9) & (10))

Under federal tax law, all property acquired from a decedent is statutorily deemed to have been held for more than one year (long-term).

• It makes no difference how long the decedent actually owned the property prior to death.
• It makes no difference how long the beneficiary holds the property before selling.
• Exam Scenario: A taxpayer inherits publicly traded stock on Monday and sells it on Wednesday of the same week. The transaction is reported on Form 8949, Part II (Long-Term), and any gain or loss is long-term capital gain or loss.

The Alternate Valuation Date (AVD): IRC §2032

The executor or personal representative of an estate may make an irrevocable election under IRC §2032 on Form 706 (United States Estate Tax Return) to value estate assets on the Alternate Valuation Date (AVD) rather than the date of death.

Statutory Mechanics of the AVD Election:

1. Timing: The Alternate Valuation Date is precisely six months after the date of the decedent's death.
2. Two-Prong Statutory Test (IRC §2032(c)): The executor can elect the AVD ONLY if the election results in a decrease in BOTH:
   • The total value of the decedent's gross estate; AND
   • The total net amount of federal estate tax and generation-skipping transfer (GST) tax liability (after allowable credits).
   • Exam Trap: An executor cannot elect AVD solely to step up basis higher, nor can AVD be elected if no federal estate tax is owed (e.g., estate is below the federal filing threshold or sheltered entirely by the unlimited marital deduction).
3. Interim Disposition Rule: If estate property is sold, exchanged, distributed to heirs, or otherwise disposed of within the 6-month window between the date of death and the AVD, that specific property is valued on the date of distribution or sale, not the 6-month date.

Community Property vs. Common-Law States: The Double Step-Up

State property laws dramatically alter the basis of property owned jointly between married spouses upon the death of the first spouse under IRC §1014(b)(6):

1. Common-Law / Separate Property States (41 States)

• Spouses typically hold real estate and investments as Joint Tenants with Right of Survivorship (JTWROS) or Tenancy by the Entirety.
• Under IRC §2040(b), each spouse is deemed to own a 50% interest.
• Upon the death of the first spouse, only the decedent's 50% interest is stepped up to FMV. The surviving spouse's 50% interest retains its original historical cost basis.
• Result: A partial 50% basis step-up.

2. Community Property States (9 States: AZ, CA, ID, LA, NV, NM, TX, WA, WI)

• Under IRC §1014(b)(6), if at least one-half of the whole of the community interest in property was includible in determining the decedent's gross estate, 100% of the community property—both the decedent's half AND the surviving spouse's half—receives a stepped-up basis to FMV on the date of death.
• This extraordinary tax benefit is known as the "Double Step-Up" in Basis.

Numerical Comparison: Common-Law vs. Community Property

Fact Pattern: John and Mary purchased a parcel of investment land (non-depreciable) for $400,000 ($200,000 each). When John dies, the land has a fair market value of $2,000,000. Mary sells the land two months later for $2,000,000.

• If Common-Law State (50% Step-Up):
  • Mary's retained basis = $200,000
  • John's stepped-up basis = $1,000,000 (50% of $2,000,000 FMV)
  • Mary's new adjusted basis = $1,200,000
  • Recognized Capital Gain on Sale = $2,000,000 proceeds - $1,200,000 basis = $800,000 Gain.
• If Community Property State (100% Double Step-Up under §1014(b)(6)):
  • Both halves step up to date-of-death value.
  • Mary's new adjusted basis = $2,000,000
  • Recognized Capital Gain on Sale = $2,000,000 proceeds - $2,000,000 basis = $0 Gain.

Exception to Stepped-Up Basis: Income in Respect of a Decedent (IRD)

Under IRC §1014(c), the stepped-up basis rule does NOT apply to Income in Respect of a Decedent (IRD) governed by IRC §691.

• Definition of IRD: Income that the decedent had earned or had a right to receive prior to death, but which was not properly includible on the decedent's final income tax return under their method of accounting.
• Tax Treatment: IRD receives ZERO step-up in basis. The beneficiary steps directly into the decedent's shoes and must report the income as ordinary taxable income in the year received, retaining the same character it would have had in the hands of the decedent.
• Common IRD Assets:
  • Traditional IRA and 401(k) / 403(b) account balances
  • Unpaid wages, salaries, bonuses, and accrued vacation pay earned prior to death
  • Deferred compensation and nonqualified stock option gains
  • Accrued interest on Series EE and Series I U.S. Savings Bonds not previously recognized
  • Uncollected payments on installment sales notes under IRC §453
  • Accounts receivable of a cash-basis sole proprietorship
• Estate Tax Deduction (IRC §691(c)): To prevent double taxation of the same asset under both the estate tax and the income tax, a beneficiary who includes IRD in gross income is permitted to claim a miscellaneous itemized deduction on Schedule A (not subject to the 2% AGI floor) for the federal estate tax attributable to that specific IRD item.
