According to Regulation §1.1245-2(b), a taxpayer is generally required to report all gains or losses on the disposition of capital assets, including the transactions giving rise to capital gains or losses, in a separate computation on the tax return (Reg. §1.1202-1(a)). However, there is no statutory authority that requires the reporting of a full tax-deferred exchange. In any event, it may be wise planning to attach a schedule to report a problematic exchange to start the statute of limitations running on the issue.
An exchange of like-kind property may be reported on Schedule D or on Form 4797, whichever applies. The instructions to Schedule D (Form 1040) state that all exchanges must be reported. The instructions apply to even fully tax-deferred exchanges. Thus, while again there is no statutory authority for this instruction, it does present a dilemma. On the one hand, those who are more aggressive in their tax compliance will probably continue to report as little as possible based upon the reasoning that if your exchange is non-taxable, the IRS would not impose a penalty at a later date. On the other hand, conservative advisors such as Cornerstone will usually recommend that their client report the exchange even where no tax is generated, in order to start the clock running on the statute of limitations. If the taxpayer does choose to report the exchange, it should be done as simply as possible. A short "memo box" recapitulation on a single sheet of paper would be ideal. This recapitulation could then be attached to Schedule D or Form 4797.
If a taxpayer has a like-kind exchange, Form 8824—Like-Kind Exchanges must be filed in addition to Schedule D or Form 4797. Form 8824 requests specific information about the exchange including:
