The rules the exam tests
| Rule | What it says (2025) | Source |
|---|---|---|
| Purchased property | Cost, including sales tax, freight, installation and settlement costs | IRC 1012; Pub 551 |
| Inherited property | FMV at date of death (or alternate valuation date); holding period always long-term | IRC 1014, 1223(9) |
| Gift, FMV >= donor basis | Donor's basis (plus gift tax on appreciation); donor holding period tacks | IRC 1015 |
| Gift, FMV < donor basis | Gain basis = donor basis; loss basis = FMV at gift; in-between sale = no gain or loss | IRC 1015(a) |
| Stock splits / nontaxable stock dividends | Spread existing basis over all shares | IRC 307 |
| Wash sale | Disallowed loss added to replacement shares' basis | IRC 1091 |
| Adjustments | Add improvements; subtract depreciation allowed or allowable, casualty losses, credits | IRC 1016 |
Facts: Dad bought land for $40,000. When it was worth $30,000 he gave it to Ana. Ana sells.
| Ana sells for | Basis used | Result |
|---|---|---|
| $45,000 | $40,000 (gain basis) | $5,000 gain |
| $25,000 | $30,000 (loss basis) | $5,000 loss |
| $35,000 | neither works | no gain or loss |
Had Dad died and left her the land worth $30,000, her basis would simply be $30,000.
Exam traps
- Inherited property is long-term regardless of holding period.
- Dual basis applies only when FMV at the gift is below the donor’s basis.
- Depreciation “allowable” reduces basis even if never claimed.
- Points on a home loan are not part of basis; title and recording fees are.

Frequently asked questions
What is stepped-up basis?
Property acquired from a decedent takes a basis equal to its fair market value at death, erasing pre-death appreciation for income tax.
What basis do I use for gifted stock?
Generally the donor’s basis. If the stock was worth less than the donor’s basis when given, use that lower value to compute a loss.
