Related Party Rules Under Section 1031(f)

Related Party Rules Under Section 1031(f)

Section 1031(f) imposes special rules when the relinquished property or the replacement property in an exchange involves a related party. The rule is intended to prevent related parties from using an exchange to shift basis between properties without any genuine change in economic position.

Who Counts as a Related Party

The related party definition draws on Section 267(b) and Section 707(b)(1) of the Internal Revenue Code. It generally includes close family members, such as siblings, a spouse, ancestors, and descendants, along with entities in which the investor holds more than fifty percent ownership.

The Two Year Holding Requirement

If either party disposes of the property received in a related party exchange within two years of the last transfer, both parties may lose the benefit of deferral and must report gain as of the date of the later disposition. This applies even if the original exchange was structured correctly at the time it closed.

Exceptions to the Two Year Rule

  • Disposition following the death of either party to the exchange
  • Disposition as part of a compulsory or involuntary conversion
  • A showing, to the satisfaction of the Internal Revenue Service, that neither the original exchange nor the later disposition had tax avoidance as a principal purpose

Why the Rule Exists

Without the two year requirement, related parties could exchange a low basis property for a high basis property between themselves, then immediately sell the low basis property using the high basis of the other party, avoiding gain recognition without any real change in ownership across the family or entity group.

Related Party Exchanges Using a Qualified Intermediary

Using a qualified intermediary does not automatically exempt an exchange from the related party rules if the relinquished property or the replacement property is ultimately transferred to or from a related party as part of the same overall transaction. The Internal Revenue Service has challenged structures designed to avoid Section 1031(f) through the use of an intermediary.

DC Metro Family and Entity Transactions

Related party exchanges arise often among family owned commercial property in Washington DC, where a parent may exchange out of a District property held for decades while an adult child or a family entity retains an interest in the replacement property. These transactions require careful documentation of the two year holding period and the business purpose behind the structure.

Reporting the Related Party Exchange

IRS Form 8824 includes specific questions addressing whether the relinquished or replacement property was exchanged with a related party. Both parties to a related party exchange typically must file this disclosure with their federal returns for the year of the exchange, and again in the following year to confirm the two year holding requirement remains satisfied. Incomplete or inconsistent related party disclosures between the two parties can draw additional scrutiny during any subsequent review.

District of Columbia Income Tax Treatment If Deferral Is Reversed

If a related party exchange fails the two year holding requirement and gain becomes recognized, an investor who is a District of Columbia resident faces District income tax on that gain in addition to the federal tax. The District taxes capital gains as ordinary income under its graduated bracket system, with rates reaching 10.75 percent for taxable income above $1,000,000, rather than applying a separate, lower capital gains rate. Because the related party rule can reverse deferral years after the original exchange closed, investors should keep documentation of the original transaction on hand well beyond the two year window.

Structuring Family Transactions to Support the Two Year Rule

Families considering a related party exchange in the Washington DC metro area should document the independent business purpose for the transaction at the time it occurs, rather than reconstructing that record later if the arrangement is questioned. Evidence such as appraisals supporting fair market value, separate legal representation for each party, and a written explanation of why the exchange serves the independent investment goals of each party can support the position that tax avoidance was not a principal purpose of the transaction.

Frequently Asked Questions

Can an investor exchange property directly with a sibling?

Yes, but the exchange is subject to the two year holding requirement under Section 1031(f). Gain deferral can be reversed if either party disposes of their respective property within two years of the exchange.

Does the two year rule apply if a qualified intermediary is used in a related party transaction?

The two year rule can still apply. Using a qualified intermediary does not eliminate the related party analysis if the ultimate result of the transaction involves related parties on either end of the exchange.

What happens if a related party exchange fails the two year holding requirement?

Both parties to the related exchange generally must recognize the gain they originally deferred, reported as of the date of the disqualifying disposition, rather than the original exchange date.
