The 2025 Tax-Law Change That Just Reset the Math for Real Estate Investors
A provision most property owners still haven't heard about made one of real estate's biggest tax advantages permanent — and more valuable than it's been in years. Here's what changed, and what it could mean for your property.

or years, one of the most powerful tax tools in real estate was on a countdown to zero.
In July 2025, that countdown didn't just stop. It reversed.
If you own investment property, the change is worth two minutes of your attention — because it quietly reset the math on how much of your property you can deduct, and when.
What was happening before
The tool is called bonus depreciation: the rule that lets you deduct the full cost of certain short-life property in the year you put it to use, instead of spreading it across years.
Under the 2017 tax law, bonus depreciation had been set at 100% — but it was scheduled to phase out. It had already stepped down to 80% in 2023 and 60% in 2024, sat at 40% for 2025, and was headed to zero by 2027. Investors who understood it were racing the clock, trying to place property in service before the benefit shrank further.
Then the rule changed.
What changed in 2025
The One Big Beautiful Bill Act (P.L. 119-21) was signed into law on July 4, 2025. Among its provisions, it permanently restored 100% bonus depreciation for qualifying property acquired and placed in service after January 19, 2025. The IRS confirmed the details in its own guidance, Notice 2026-11.
The phase-down didn't just pause — it was eliminated, and the 100% rate was made permanent.
Old rates reflect the Tax Cuts and Jobs Act phase-down; the permanent 100% rate is per the One Big Beautiful Bill Act (P.L. 119-21) and IRS Notice 2026-11.
Why this matters for real estate specifically
Here's the connection most property owners miss.
Bonus depreciation only applies to property with a recovery period of 20 years or less. A building, by itself, doesn't qualify — under IRS rules it's depreciated over 27.5 years (residential rental) or 39 years (commercial). So on its own, your building can't take advantage of this at all.
But a building isn't really one asset. A cost segregation study — an engineering-based analysis — identifies the components of your property that legally qualify for much shorter schedules: 5, 7, and 15 years (Publication 946). And those shorter-life components are exactly the kind that qualify for 100% bonus depreciation.
Recovery periods per IRS Publication 946 & 527; bonus eligibility for short-life components per IRS Notice 2026-11. The building shell does not qualify; only the reclassified components do.

Results are illustrative ranges for educational purposes only — not a definitive figure, quote, or tax advice. Whether a deduction is usable depends on your situation (real-estate-professional status, short-term-rental material participation, or available passive income). NR confirms eligibility before any engagement.
In other words: the 2025 change made the slice of your property that a study can reclassify deductible in full, in year one. The same study that was worth doing before is worth more now. That's the reset.
What that can look like
Illustrative — your property will differ. Take a $1,000,000 short-term rental placed in service this year. A study might reclassify a few hundred thousand dollars of it onto 5-, 7-, and 15-year schedules. Under the restored 100% bonus depreciation, much of that could be deducted in the first year rather than over decades — turning a slow trickle into a substantial first-year deduction.
Two honest caveats
We'd rather you trust us than oversell, so two things to know before you assume this applies to you:
Timing. The permanent 100% rate is tied to property acquired and placed in service after January 19, 2025. Property under a binding contract before January 20, 2025 may still fall under the old phase-down rates. The exact dates matter, and they’re worth confirming for your specific purchase.
Whether you can use it. A large first-year deduction only helps if you can apply it against income. That can depend on whether you qualify as a real estate professional, whether you materially participate in a short-term rental, or whether you have passive income to offset. We confirm this before recommending anything.

How to find out what it means for your property
If you bought — or are about to buy — investment property, the window is open right now, and it's worth knowing your number before your next filing rather than after.
A free Cost Segregation Savings Estimate is how you find out: a few questions, a short call, and a real dollar figure for what the current rules could be worth on your property. And if a study isn't clearly worth more than it costs for your situation, we'll tell you that on the call.

Figures are illustrative and for educational purposes only. Cost segregation accelerates the timing of depreciation deductions; it is not a tax credit and does not create a permanent reduction. Bonus-depreciation eligibility depends on acquisition and placed-in-service timing and other factors; results vary by property and individual circumstances. Not tax, legal, or accounting advice.
