There’s a reason most investors shrug—and quietly overpay—when they hear “real estate tax advisory.” It’s the fear that recent rule changes and the relentless cap on State and Local Tax (SALT) deductions have closed all the best doors.
Yet, every year, thousands of property owners leave as much as $19,500 or more sitting untouched because their CPA never flagged the most overlooked strategies.
Fast Tax Fact: Top Missed Deductions for Property Owners
If you own rental properties in 2025, you can still leverage advanced moves—like cost segregation, business asset expensing, and state deduction stacking—even as the tax landscape shifts. The IRS has kept key legal loopholes alive for those who know where to look.
What Really Changed for Real Estate Taxes in 2025?
The 2025 tax season landed with a thud for real estate owners. Here’s the quick bottom line: Depreciation rules keep tightening, bonus depreciation phases down, and the SALT cap remains glued at $10,000.
But new openings—especially around Section 179 and cost segregation—create significant savings, if you know how to structure your ownership and expenses.
- ✅ Depreciation on new residential rental property remains at 27.5 years. Shorter write-offs require cost segregation studies.
- ✅ The SALT cap ($10K) is still in effect, but strategic entity planning (like forming a pass-through LLC or S Corp at the state level) can sidestep this ceiling in select states.
- ✅ Bonus depreciation drops to 60% in 2025, down from 80%. This matters for major remodels and property upgrades.
Quick Answer: With smart tax advisory in 2025, property owners can still bank five-figure deductions, but passive investors and DIY filers risk missing out unless their approach adapts to new law changes.
Section 179 Is No Longer Just for Businesses: Rental Assets Can Qualify
Most rental owners (and surprisingly, many CPAs) believe Section 179 only benefits active businesses. But since recent rule clarifications, landlords who provide furnished rentals—or run short-term rental businesses—can use Section 179 to expense many assets outright, instead of depreciating them slowly.
The $5,500 Immediate Write-Off Using Real Estate Tax Strategies
Erin owns a duplex and spends $5,500 on new energy-efficient appliances for her short-term rental unit. If she qualifies as running an “active rental business,” she can elect Section 179 and instantly deduct the entire cost this year, versus spreading that deduction over five or more years.
That means real tax savings of $1,600+ at the 28% bracket—fast, legal, and IRS-approved.
How Do You Qualify for These Real Estate Tax Strategies?
Your rental must rise to the level of a business, not a passive investment, typically requiring regular services like cleaning, amenities, and guest interactions.
You’ll also need to file Form 4562 with your return and keep receipts for all purchases.
Follow-Up: What If My Rental Is Passive?
If you’re a long-term landlord with little day-to-day involvement, Section 179 usually doesn’t apply. But you may still unlock substantial savings by reviewing cost segregation in the next section.
Slicing Through the SALT Deduction Cap—Legal State Strategies in 2025
The $10K SALT cap—limiting deductible state and property taxes—has hit real estate owners in high-tax states hardest.
Yet, 30+ states have now adopted “pass-through entity tax elections” (PTET), letting S Corps or LLCs pay state taxes (and deduct them fully!) at the entity level. This strategy re-opens $8,000–$15,000 in lost deductions for qualifying owners.
Scenario: The $12,000 Deduction Recovery
Russ co-owns an apartment building in California.
By electing PTET status on his LLC, the business pays $14,000 in state tax, which is then deducted on the business return, not subject to the $10K SALT cap on his personal return.
For Russ, this move restored $12,000 in deductible expenses previously denied.
- • This approach requires correct entity setup and state/PTET paperwork—don’t try it without professional tax advice.
- • Available in most “high tax” states, including NY, CA, IL, and NJ. Check your state’s rules for specifics.
What If My Properties Are Held Personally?
Direct ownership means you’re stuck with the $10K cap. Consider moving properties to an entity (with legal guidance) to benefit from PTET and other advanced strategies.
Bonus: Cost Segregation Analysis—A Real Estate Tax Strategy That Creates Five-Figure Deductions
Cost segregation isn’t just for massive portfolios.
Any owner with property worth over $300K can often carve out $25,000 or more in extra first-year deductions by breaking buildings into faster-depreciating components—HVAC, appliances, paving, land improvements, etc.
The $19,500 Tax Windfall Real Example
Daria buys a four-plex for $800,000. With a cost segregation analysis, she reclassifies $110,000 in property components (carpeting, lighting, landscaping) as 5- or 15-year assets, not 27.5-year property. This boosts her year one depreciation, netting $19,500 in extra deductions.
Daria’s actual after-tax savings, at her 31% combined bracket: nearly $6,000 back, this year.
- ✅ Requires professional engineering study for IRS compliance.
- ✅ Can be combined with Section 179 for even bigger hits—ask your advisor to model a “double dip.”
Who’s the Best Candidate for These Real Estate Tax Strategies?
- Owners with single residential or mixed-use properties over $300K.
- Investors planning major improvements or who have just completed a large property purchase.
The Documentation Trap That Can Undermine Your Real Estate Tax Strategies
The IRS cracks down hardest on deductions that lack proper support. The two biggest traps: missing cost segregation reports and poorly substantiated PTET elections.
The fastest way to end up in audit hell is to guess at asset lives or skip entity-level election forms.
- ✅ Always file the right forms. Cost seg studies need a formal report; PTET elections often require additional state filings.
- ✅ Save receipts, invoices, and professional provider reports for at least 3 years after your deduction (preferably 7).

FAQs and Troubleshooting: What Property Owners Ask Next
What If I Bought My Rental Mid-Year?
You can still claim a prorated share of depreciation, even if you owned it for only 3 months in 2025. Report on Form 4562 and keep settlement statements handy.
Does an S Corp or Partnership Always Beat Personal Ownership?
No. Entities add cost and complexity. The benefit for real estate is mostly in large or multi-state holdings, SALT cap workarounds, or group investments. Solo residential landlords may be better off sticking with Schedule E and classic depreciation. Speak with tax pros before converting.
Can I Skip Cost Segregation for Small Properties?
It’s optional—but on properties worth $200K+, the payback is real. For $80K-$175K homes, focus on classic depreciation but never ignore repairs and immediate write-offs.
Will These Strategies Trigger an Audit?
Not if you have ironclad documentation and follow the published IRS rules—including professional studies and completed PTET/state forms. The real risk comes from “DIY” cost segregation or stretching the definition of ‘active business’ for Section 179.
