A client comes back from a dinner party convinced he’s found a way to erase his tax bill. Someone told him about bonus depreciation. He wants to buy an apartment building and stop paying the IRS. Now it’s your job to tell him whether that’s real, where it breaks and how to keep himself out of trouble.
It is real. But the version he heard at dinner is missing the parts that matter, and those are exactly the parts you get paid to know.
The strategy has two halves: a deduction large enough to wipe out a year’s income, and the permission to actually use it against that income. Get either half wrong, and you’ll misjudge what your client is signing up for.
Cost Segregation and Bonus Depreciation
The IRS assigns an apartment building a 27.5-year depreciation schedule. That spreads the paper loss thin. But a building isn’t one asset. It’s hundreds of them: HVAC units, water heaters, cabinets, wiring, flooring, fixtures. A cost segregation study breaks the property into components and reassigns each to its own schedule. On a typical deal, 30% to 40% of the purchase price lands on schedules of 20 years or less.
That threshold is the whole point, because anything on a sub-20-year schedule qualifies for bonus depreciation. The One Big Beautiful Bill made 100% bonus depreciation permanent, which means your client can deduct the full reclassified value in year one. On a $10 million complex with a million in non-depreciable land, a cost seg study might move $3 million onto short schedules. That’s a $3 million paper loss the year the deal closes, against a property that’s appreciating and throwing off rent the entire time.
That’s the deduction. The harder half is earning the right to use it.
The REPS Designation
By default, rental losses are passive. They offset passive income only: rental income, dividends and gains on investments your client sells. They do not touch W-2 wages. For the executive earning a million in salary with his wealth parked in stock, he isn’t selling; that limitation guts the strategy. The $3 million loss has nothing to offset.
The $25,000 active-participation exception, which is often mentioned as a workaround, phases out entirely at $150,000 of AGI. For your clients, it doesn’t exist.
The way past the passive wall is real estate professional status under Section 469(c)(7). Here’s where most explanations of this strategy mislead: REPS is not a single test. It’s two statutory tests, plus a separate participation requirement. And meeting the criteria usually isn’t quite as straightforward for a W-2 executive as it’s made out to be.
Test one requires that more than half of all the personal-service hours your client works in any trade or business during the year fall in real property businesses. Test two requires more than 750 hours in those real property businesses.
The 750-hour number gets all the attention, but the more-than-half test is the one that breaks high earners. An executive logging 2,000 hours at a non-real-estate day job would need more than 2,000 hours in real estate to clear it. The Tax Court is openly skeptical of full-time professionals who claim they spent the majority of their working time on real estate, and that skepticism is where audits are won and lost.
In practice, this is why the qualifying spouse is usually the one who isn’t carrying a full-time W-2 job elsewhere. On a joint return, only one spouse needs to pass these two tests, but the hours can’t be pooled between spouses to get there. One person has to clear both bars alone.
That’s still not all. Your client must then materially participate in the rental activity itself, which is a third hurdle under its own set of rules. There are seven tests to choose from, but most investors lean on a 500-hour requirement per activity per year.
The IRS treats each property as a separate activity by default, meaning the 500-hour test has to be met property by property. Five buildings can mean five separate 500-hour proofs.
The fix is a grouping election, which lets your client treat the entire rental portfolio as a single activity so that the hours combine. It’s filed as a statement attached to the return, and it’s effectively binding going forward. Spousal hours, which can’t help with the two REPS tests, can be combined here for material participation.
Making It Count
When the asset is sold, depreciation recapture is due at 25%. Your client deferred at a 37% marginal rate, so the spread is real money kept. The bigger advantage is time. Tax dollars that would have gone to the Treasury stay invested, compounding, for years before recapture lands. The strategy doesn’t decide whether your client pays. It decides when, and on what terms.
But that’s only if the client sells. Real estate offers another unique provision: the 1031 exchange. So long as the money always passes through escrow, their $1 million building becomes a $5 million building, becomes a $10 million building with the deferred tax riding along the entire way. If they keep deferring until they die, their heirs could even inherit their untaxed wealth at a stepped-up basis.
That’s how you help your client build generational wealth.
