Glossary, in brief
Like-kind (high level)
For real property, “like-kind” is a holding-purpose and property-kind question, not a “same street” test. Confirm both sides with a CPA.
Timing windows
Identification and receipt windows exist in IRC §1031 procedure. This page does not invent 2026 day-count changes and does not start your clock. Verify the current IRS like-kind exchange materials before you list or close.
Basis carryover
Replacement basis often starts from given-up basis and then moves for money and recognized gain. That is a concept, not a Form 8824 total from this site.
Gain flavors
Depreciation recapture ideas (including unrecaptured §1250) and NIIT may apply. We will not output a fake IRS tax due from invented 2026 LTCG or NIIT rates.
