Recapture on a Converted Home or Rental

Converting a home to a rental

Once you rent it out, you depreciate the building. That depreciation is subject to recapture (up to 25%) when you eventually sell, even if you later move back in.

Converting a rental to your home

Living in a former rental for two of the last five years can qualify part of the gain for the Section 121 exclusion — but the exclusion does not cover depreciation recapture taken after May 6, 1997.

Nonqualified use

Periods of rental use count as nonqualified use, reducing the share of gain you can exclude. The recapture portion is always taxable regardless of the exclusion.

How the Section 121 exclusion works

The home-sale exclusion under Internal Revenue Code Section 121 lets you exclude up to $250,000 of gain ($500,000 for married couples filing jointly) on the sale of a home you owned and used as your main residence for at least two of the five years before the sale. The two years don't have to be continuous, and you generally can't use the exclusion more than once every two years.

For a converted property, the catch is that the exclusion applies to appreciation, not to the depreciation you claimed while it was a rental. Section 121(d)(6) explicitly carves out gain attributable to depreciation taken after May 6, 1997 — that slice is taxed no matter how much of the rest you exclude.

A worked example: rental converted to home

You bought a house as a rental for $300,000, claimed $60,000 of depreciation over several years (adjusted basis $240,000), then moved in and lived there two full years before selling for $560,000. Your total gain is $560,000 − $240,000 = $320,000.

First, the $60,000 of depreciation is unrecaptured Section 1250 gain, taxable at up to 25% (~$15,000) — the exclusion can't touch it. That leaves $260,000 of remaining gain. If you're single, you exclude $250,000 and pay capital-gains tax on the last $10,000; if married filing jointly, the full $260,000 is likely excluded. Either way, the depreciation slice is always on the table — a common and unpleasant surprise for owners who assumed moving back in made the whole gain tax-free.

Nonqualified use and the post-2008 proration rule

Since the Housing Assistance Tax Act of 2008, periods of 'nonqualified use' after December 31, 2008 reduce your exclusion. Nonqualified use is time the home was not your principal residence — for example, years you rented it. The excludable gain is prorated: the exclusion covers only the fraction equal to qualified use ÷ total ownership period.

An important asymmetry: rental use before you first make it your residence generally counts as nonqualified use, but rental use after you've lived in it and then move out (within the 5-year window) is not automatically nonqualified. The ordering of your use matters, so map out the exact months of personal vs. rental use before you sell. Depreciation recapture, note, is layered on top of this proration — it's taxable regardless of how the nonqualified-use math turns out.

Converting a home to a rental first

The reverse conversion has its own rules. Once you rent out a former home, you must depreciate the building (over 27.5 years) starting at the lesser of your adjusted basis or the property's fair market value at the date of conversion. That depreciation is fully subject to recapture when you sell, even if you later move back in.

Timing the sale also matters: to use any Section 121 exclusion you still need two years of personal use within the five years before sale, so a home rented out for many years can lose exclusion eligibility entirely if you wait too long to sell or move back in.

How it's reported and taxed

On sale, you report the transaction on Form 4797 for the business-use (rental) portion and recapture, and on Schedule D for the capital-gain portion; the excluded amount is claimed per the Schedule D and Form 8949 instructions for a principal residence. The depreciation recapture flows to the Unrecaptured Section 1250 Gain Worksheet and is capped at 25%. Add the 3.8% Net Investment Income Tax if your income is high enough, and remember most states don't offer a home-sale exclusion as generous as the federal one and tax the recapture as ordinary income.

Planning around the conversion

A few moves can soften the bill. Time your two years carefully so you clearly meet the ownership-and-use test before selling. Keep meticulous records of the conversion-date value, improvements, and every year of depreciation claimed — you owe recapture on 'allowed or allowable' depreciation whether or not you deducted it, so precise figures protect you. Consider whether a 1031 exchange (while it's still a rental) better fits your goals than the exclusion, since 1031 defers both the recapture and the gain but requires you not to convert to personal use for a safe period. And run the numbers before you move: sometimes selling as a rental and exchanging, or selling as a residence and paying recapture, is clearly better than the other, and the difference can be tens of thousands of dollars.

The 'lesser of' basis rule when you convert to a rental

A trap specific to converting a home into a rental: for depreciation purposes, your starting basis is the lesser of your adjusted cost basis or the property's fair-market value on the conversion date. If your home has declined in value, you depreciate off the lower market value, not what you paid. This also affects the loss calculation if you later sell at a loss. Get a dated valuation at conversion and keep it — the conversion-date figure anchors both your depreciation deductions and, eventually, your recapture calculation, and reconstructing it years later is difficult.

A worked example: home converted to a rental, then sold

You buy a home for $340,000 ($60,000 land, $280,000 building) and live in it four years. You then convert it to a rental (fair market value $360,000 at conversion, so you depreciate off your $280,000 building basis) and rent it for six years, claiming about $61,000 of depreciation. You sell for $500,000 with $30,000 of selling costs.

Because you lived there only four of the last five years before conversion but rented for six years after, you no longer meet the two-of-five-years test at sale — the Section 121 exclusion is unavailable, and the entire gain is taxable. Your adjusted basis is $340,000 − $61,000 = $279,000; amount realized is $470,000; total gain $191,000. The $61,000 of depreciation is unrecaptured Section 1250 gain (up to 25%), and the remaining $130,000 is long-term capital gain. This is why timing the sale within the five-year window — or exchanging instead — matters so much.

Timing is everything: don't lose the exclusion window

The Section 121 exclusion requires two years of ownership and use as your principal residence within the five years ending on the sale date. If you convert a home to a rental and wait too long to sell, you can blow through that five-year window and forfeit the exclusion entirely. The practical rule: if you want the exclusion on a former residence, sell within three years of moving out (so you still have two of the prior five years as your residence). If you've already passed that point, a 1031 exchange may be the better tool, since the exclusion is gone anyway.

How military and certain other taxpayers get extra time

There's a valuable exception. Qualifying members of the uniformed services, Foreign Service, and intelligence community on qualified official extended duty can suspend the five-year test for up to 10 years. That means a servicemember who rents out a home during a long deployment or assignment can still meet the two-of-five-years test years later than a civilian could. The suspension has limits and conditions, so confirm eligibility, but it can preserve a $250,000/$500,000 exclusion that would otherwise be lost — while, as always, still not sheltering the depreciation recapture.

Common mistakes on converted properties

The recurring errors: assuming the exclusion makes the whole sale tax-free (it never covers depreciation recapture); forgetting to depreciate while it's a rental and then owing recapture anyway on 'allowed or allowable' depreciation; losing the five-year window by renting too long before selling; miscounting nonqualified use for periods after 2008; and failing to document the conversion-date value and the land/building split. Each of these can add thousands to a tax bill or trigger an IRS adjustment. Keep clean records from the day you convert, and model the sale under both the exclusion and a 1031 exchange before you decide which path to take.

The bottom line for converted properties

Whichever direction you convert — home to rental or rental to home — hold onto one core fact: depreciation recapture survives the home-sale exclusion. The Section 121 exclusion is a powerful benefit on appreciation, but the slice of gain equal to depreciation taken after May 6, 1997 is always taxable at up to 25%. Add to that the post-2008 nonqualified-use proration, the two-of-five-years window, and the lesser-of-cost-or-market rule at conversion, and it's clear these sales reward planning. Estimate the recapture and the excludable gain separately, confirm you still meet the residency test, and weigh a 1031 exchange as an alternative while the property is still a rental. A short session with the numbers — or a tax professional — before you list can be worth many thousands of dollars.
