How do I report a condemnation on my tax return under section 1033?

Which form depends on what the property was, not on the election

The Form 4797 instructions put "the involuntary conversion (from other than casualty or theft) of property used in your trade or business" on Form 4797, and list condemnation, threatened or carried out, among the section 1231 transactions reported in Part I where the property was held more than one year. Publication 544 confirms that the condemned property must have been held longer than one year and be business property or a capital asset held in connection with a business to be a section 1231 transaction.

A capital asset not used in a business, such as a parcel of raw land held purely for appreciation, goes elsewhere: the instructions send "gains from involuntary conversions (other than casualty or theft) of capital assets not used in your trade or business" to Form 8949 and Schedule D. Casualties and thefts begin on Form 4684 and flow to Form 4797 from there, but a taking is not a casualty, so Form 4684 is not part of a condemnation filing.

The section 1231 gain glossary entry explains why the Part I character matters: a net section 1231 gain is long-term capital gain, a net loss is ordinary. The condemnation filing is simpler than an exchange filing because nothing passes through Form 8824.

The first return: the statement, the omitted gain and the figures that must be right

Publication 544 says you "report gain or loss from a condemnation on your return for the year you realize the gain or loss", and for a cash-basis owner that is the year payments above basis arrive, including partial payments. A condemnation award paid in installments covers how that year is identified.

The deferral is claimed by attaching a statement for that year describing the conversion and by not including the deferred gain in income; Reg. section 1.1033(a)-2(c)(2) requires "all of the details in connection with an involuntary conversion of property at a gain" to be reported in that return and treats the omission of the gain as the election itself. Publication 544 adds that if you have already bought the replacement, the statement carries its details too.

Three numbers drive the statement. The net award: gross award less legal, engineering and appraisal fees, plus amounts the authority paid to a lender, as Publication 544 computes it. The adjusted basis of the property taken, with depreciation to the date of disposition. And the cost of the replacement, if bought. Interest the authority paid for delay is left out of all three and reported as ordinary income on its own line.

• Date and description of the taking, and the authority involved.
• Gross award, expenses of obtaining it, and amounts paid to lienholders.
• Adjusted basis of the property taken and the gain realized.
• Replacement property bought, its cost and date, or a statement that you intend to replace within the period.

The second return, and the one you file if the plan changes

When the replacement is bought in a later year, Publication 544 has you attach a statement to the return for that year with the details of the purchase. The regulation requires the same, and section 1033(a)(2)(C) makes that notice the event that starts the three-year assessment period on the deferred gain, so the second statement is not optional even where the purchase was described in advance.

If you fail to replace, replace for less than you stated or decide not to replace, the regulation requires the original year's tax to be recomputed on an amended return, Form 1040-X for individuals. If you reported and paid on the gain and later decide to defer, the route is a claim for credit or refund before the replacement period ends. Electing section 1033 on an amended return walks through both.

Severance damages are a separate conversion of the land you keep, with their own basis reduction and their own gain figure, and whether severance damages count toward the award explains the split. Report them as a second line, not folded into the award.

Recapture, Part III and the lines that catch partial reinvestment

If any gain is recognized because the replacement cost less than the award, Publication 544 warns that the recognized gain may be ordinary income from depreciation recapture, computed in Part III of Form 4797 under the section 1245 and 1250 rules. The instructions note the involuntary-conversion exceptions in sections 1245(b) and 1250(d), which cap the recapture at the gain recognized with adjustments. Depreciation recapture on a condemnation sets out the caps and the cost-segregation trap.

A loss on condemned business or investment property goes on Form 4797 like any other section 1231 loss; a loss on personal-use property is not reported, as Publication 544 states.

Entity returns and a DST interest on the statement

Where a partnership or corporation owned the property, Publication 544 says only the entity can elect, so the statement and the Form 4797 go with the entity's return and the partners' K-1s carry the result; who makes the election for a partnership or LLC explains the case law behind that rule. The replacement property rules and timeline page covers what the purchase must satisfy.

If the replacement described is a DST interest, the statement should say so plainly and the file should hold tax counsel's written view, because no ruling, regulation or opinion says a trust interest is section 1033 replacement property, and a trust interest is illiquid with equity that can be lost. DSTs for 1033 proceeds sets out the arguments on each side.
