Property Was Destroyed or Condemned. Can the Gain Be Deferred?

Section 1033 can defer gain when property is involuntarily converted and qualifying replacement requirements are satisfied.

Involuntary conversion

A casualty, theft, condemnation, or similar involuntary event can convert property into insurance proceeds or condemnation proceeds.

Replacement property

Gain deferral can depend on acquiring qualifying replacement property within the applicable replacement period.

Reinvestment

When proceeds are not fully reinvested, some gain can become currently recognized under the applicable rules.

Basis

Deferred gain is generally preserved through basis adjustments in the replacement property.

The takeaway

Calculate realized gain first, then determine how much proceeds were reinvested in qualifying replacement property and whether the statutory timing rules were met.
