Why investors keep 1031-ing forever

A 1031 exchange (Like-Kind Exchange) defers federal capital gains + depreciation recapture indefinitely if you roll proceeds into another investment property within 180 days. The tax bill on a typical investor sale is 25-35% of the gain — kicking that to the next sale, then the next, then never (step-up basis at death) is the most common path to compounding wealth in real estate.

The math the IRS runs

adjusted basis = original basis − depreciation taken
total gain = sale price − adjusted basis
recapture amount = depreciation taken (capped at gain)
LTCG gain = total gain − recapture amount
tax = recapture × 25% + LTCG × 20% + state × full gain

FAQ

What's depreciation recapture?

When you sold a rental, the IRS 'recaptures' the depreciation deductions you took along the way — taxing them at 25% (Section 1250 unrecaptured gain). Even if your overall gain qualifies for 20% LTCG, the depreciation portion gets the 25% rate. A 1031 defers both.

Can I exchange into a different state?

Yes. The 'like-kind' rule for real property is generous — exchange a CA fourplex for a TX commercial strip, totally fine. State income tax follows the property: when you eventually sell out (no 1031), you owe the source state's tax. CA has the 'clawback rule' to track that.

What if the replacement is cheaper?

The difference is 'boot' and is taxable as gain. To fully defer, replacement value must be equal to or greater than relinquished property AND replacement debt must be equal to or greater than relinquished debt. Most investors trade up to maintain full deferral.
