When Gain Is Realized But Not Recognized: A Guide to Nonrecognition Provisions

There are numerous situations under the Internal Revenue Code where gain is realized but not recognized for tax purposes. Understanding the distinction is foundational to tax planning — and to avoiding costly surprises.

Realized means an economic gain occurred. Recognized means the gain must be reported on a tax return and subjected to current taxation. Congress has created several exceptions that defer or permanently exclude recognition, generally when the taxpayer's economic investment continues in a modified form rather than being converted into cash.

One of the most widely used nonrecognition provisions in real estate.

If business or investment real estate is exchanged solely for other qualifying real estate, gain is generally deferred — not eliminated. The deferred gain carries over into the replacement property's basis.

Example:

The $400,000 gain is preserved in the replacement property and recognized only upon a future taxable disposition — unless another §1031 exchange is completed.

For a deeper look at how this interacts with depreciation, see our post on depreciation recapture.

No gain is recognized when:

• Property is transferred to a corporation,
• Solely in exchange for stock, and
• The transferors own at least 80% of the corporation immediately after the exchange.

This rule facilitates business formation and restructuring without triggering immediate taxation. The gain defers into the corporation's basis in the transferred property and the shareholder's basis in the stock received.

Generally, no gain is recognized when property is contributed to a partnership in exchange for a partnership interest.

Example:

Important exceptions apply, including disguised sales under IRC §707, where a contribution paired with a distribution may be recharacterized as a taxable sale.

Many mergers, consolidations, and restructurings qualify as tax-free reorganizations. Common types include:

• Statutory mergers (Type A)
• Stock-for-stock exchanges (Type B)
• Certain asset acquisitions (Type C)
• Recapitalizations (Type E)

The policy rationale is straightforward: when ownership continues in a modified corporate form, Congress generally permits the transaction to occur without immediate tax. Gain defers into the basis of stock or assets received.

The recipient generally does not recognize gain when receiving a gift. Instead, the donor's basis carries over to the recipient. Gain is recognized only when the recipient later sells the property.

This means a gift of highly appreciated property does not trigger tax at the time of transfer — but the embedded gain follows the asset to the new owner.

Property inherited from a decedent generally receives a step-up (or step-down) in basis to its fair market value at the date of death, subject to applicable rules and exceptions.

Any appreciation during the decedent's lifetime is generally never recognized for income tax purposes.

Example:

If the heir immediately sells for $700,000, no gain is recognized. The $600,000 of appreciation accumulated during the decedent's lifetime is permanently excluded from income tax — though it may be subject to estate tax depending on the size of the estate.

This is one of the most powerful planning tools available in estate planning. For more on how this intersects with trust and estate strategy, see our Estate & Trust services.

Rather than a nonrecognition rule, this is an exclusion — gain is permanently eliminated, not merely deferred.

Qualified homeowners may exclude:

• Up to $250,000 (single filers)
• Up to $500,000 (married filing jointly)

of gain on the sale of a principal residence, provided they satisfy the ownership and use requirements (generally, owned and used as a principal residence for at least two of the five years preceding the sale).

When property is destroyed, stolen, condemned, or subject to eminent domain, gain may be deferred if qualifying replacement property is acquired within the applicable replacement period.

The replacement period is generally two years after the close of the first tax year in which any part of the gain is realized, though longer periods apply for certain property types.

Gain is generally recognized over time as payments are received, rather than entirely in the year of sale. This can significantly reduce the tax burden in the year of a large transaction.

Critical limitation: Depreciation recapture generally does not qualify for installment reporting and is typically recognized in full in the year of sale — regardless of when payments are received.

A taxpayer who sells stock at a loss and acquires substantially identical stock within 30 days before or after the sale generally cannot recognize the loss immediately. The disallowed loss is added to the basis of the replacement shares, preserving it for a future period.

Note that wash sale rules apply to losses, not gains.

Losses on sales between certain related parties are generally not recognized at the time of the sale. Related parties include:

• Parent and child
• Majority-owned corporations and their shareholders
• Certain trusts and beneficiaries

These rules are designed to prevent artificial loss recognition between parties with aligned economic interests. They generally apply to losses, not gains.

Certain capital gains may be deferred by timely investing in a Qualified Opportunity Fund, subject to statutory requirements. The gain is generally recognized upon a later triggering event or by the applicable statutory recognition date.

As noted in our depreciation recapture guide, depreciation recapture generally does not receive the same favorable treatment as eligible capital gain under Opportunity Zone rules — careful planning is required.

The tax law generally allows nonrecognition when the taxpayer's economic investment continues in a modified form rather than being converted into cash or fundamentally different property. In those cases, Congress defers taxation until a later disposition. By contrast, provisions such as the principal residence exclusion and the basis adjustment at death can permanently eliminate recognition of certain gains under the applicable statutory rules.

Understanding whether a transaction results in recognized, deferred, or excluded gain is a critical part of tax planning. The distinction directly affects cash flow, basis, and future tax liability — and the wrong assumption can result in an unexpected tax bill at the worst possible time.

These provisions do not operate in isolation. A well-structured transaction may combine several of them — for example, a §1031 exchange followed by a step-up in basis at death can permanently eliminate gain that would otherwise have been recognized across multiple generations of ownership.
