How the math works

Days to safe harbor = max(0, 730 − days elapsed). Exposure = gain × tax rate.

Related-party exchanges remain legitimate but require careful documentation. Keep the chain of title, QI escrow records, and rental records for the full 24 months plus one tax filing cycle — IRS audit letters on these structures arrive 18-30 months after exchange, and missing paperwork converts a good-faith exchange into a taxable event.

Frequently Asked Questions

2-year rule?

Both parties must hold replacement property for 2 years (26 U.S.C. § 1031(f)). If either sells within 2 years: gain recognized back to original party. IRS treats this as deferral abuse — 2 years is a hard floor, exceptions rare.

Related party definition?

Family members (spouse, kids, siblings, parents). Entities owned >50% by same person. Grantor trusts. Partnerships with common partners >50% profit/loss. Check IRC §267(b) for full list.

Workarounds?

Use unrelated QI (qualified intermediary). Related party holds 24+ months then sells freely. No plausible tax workaround under current law; §1031(f) specifically designed to prevent basis shifting.
