Unlocking Hidden Wealth: The Complete 2025 Schedule for Bonus Depreciation in California Real Estate

Some California property owners are about to miss out on tens of thousands in tax savings because they still believe bonus depreciation is gone for good. That’s a dangerous misconception in 2025 — and if you’re an investor, you simply cannot afford to make this mistake.

This year’s IRS rules and California’s franchise tax quirks have created a new window. The bonus depreciation 2025 schedule isn’t just a technicality — it’s one of the last, best ways to shelter real estate income and create instant cash flow. Anyone investing in, renovating, or holding commercial or residential property owes it to themselves to understand what’s truly available now (and what’s disappearing after 2025).

Quick Answer: How the 2025 Bonus Depreciation Schedule Works in California

For California real estate investors, the federal framework allows you to depreciate 60% of qualified property placed in service in 2025, down from 80% in 2024. California, however, does not conform — so your state return will be different. This means you get the large tax write-off on your federal return, but must adjust for California. The right moves here can result in $30,000+ in cash savings per property deal, even if your CPA says bonus depreciation is “phasing out”.

This knowledge gap creates both opportunities and traps. Get it right and you’ll lock in some of the biggest write-offs left before the law sunsets further in 2026. Get it wrong and you could overpay (twice) — first to the IRS, then again to the Franchise Tax Board.

Why Bonus Depreciation Still Matters in 2025 (Real Savings Examples)

Bonus depreciation lets you deduct a large percentage of a property or improvement’s cost upfront. It’s been the single most valuable lever for real estate operators since the Tax Cuts and Jobs Act supercharged the deduction in 2017. But the schedule is winding down:

• • 2017–2022: 100% bonus depreciation for most property
  • 2023: 80% bonus depreciation
  • 2024: 60% bonus depreciation
  • 2025: 60% bonus depreciation (phase-down continues)
  • 2026: 40% bonus depreciation
  • 2027: 20% bonus depreciation

• 2028+: No bonus depreciation

Let’s do the math for a single-family rental investor in Los Angeles:

• Property cost (excluding land): $650,000
• Cost segregation study allocates personal property: $105,000
• 2025 bonus depreciation deduction: $63,000 ($105K x 60%)
• Immediate federal tax savings (24% bracket): $15,120

For high-net-worth multifamily investors, with $5M in commercial acquisitions, bonus depreciation can push immediate tax write-offs to $300,000 (for 60% of a $500K portion identified via cost segregation), resulting in direct six-figure cash flow improvements.

KDA Case Study: Real Estate Investor Maximizes Bonus Depreciation in 2025

Monica, a mid-career real estate investor in San Diego, purchased a small apartment building in early 2025 for $2.1 million. While working with KDA, she brought up concerns from her previous CPA who insisted bonus depreciation didn’t matter anymore. We performed a full cost segregation study, identifying $320,000 in components eligible for accelerated depreciation. Thanks to the 60% federal bonus depreciation rule, Monica wrote off $192,000 in the year of purchase.

Her federal tax bracket (32%) brought $61,440 in savings for 2025, freeing capital for her next down payment. Our fee was $9,500 (including study and strategy implementation), netting Monica a 6.4x return on her investment with us — and avoiding a common pitfall of missing out due to relying on outdated advice.

Critical Federal vs. California Differences for 2025 Investors

California stands apart: it doesn’t conform to federal bonus depreciation. That means you’ll get a big win on your federal taxes, but must add back the deduction for state returns, creating higher California taxable income. The solution? Plan both returns together to sidestep cash flow shocks and avoid unplanned state tax bills.

The bonus depreciation 2025 schedule gives investors one of the last predictable windows to front-load deductions before the phase-down accelerates in 2026. Because the IRS still permits a 60% write-off for assets with a recovery period under 20 years (Form 4562 rules), cost segregation becomes significantly more valuable in properties placed in service this year. Smart operators are pairing federal bonus with §179 planning to smooth out the California addback and keep net cash flow positive even with the non-conformity. If you time acquisitions or renovations strategically, you can lock in 2025’s higher percentage without waiting for a full year of ownership.

• Federal bonus allowed: Yes (60% for 2025)
• California bonus allowed: No — adjustment required on CA Form 100 (corporate) or Form 540 (individual)
• Common mistake: Spending the refund, only to owe cash to the FTB

We recommend modeling both returns upfront and using advanced strategies to defer or offset the resulting state liability. For details, explore our real estate tax preparation services for personalized guidance.

Why Most Real Estate Investors Miss the Full Power of 2025 Bonus Depreciation

Most investors lose value by assuming their tax pro will flag every opportunity. Reality: unless your advisor specializes in real estate and actively models cost segregation, bonus depreciation often goes unexplored — especially on smaller properties or partial renovations.

Red flag alert: Many CPAs and software systems will default to straight-line depreciation, totally skipping bonus options unless specifically instructed. Always provide the cost seg breakdown and instruct your preparer to model both regular and accelerated depreciation scenarios for each asset.

Step-by-Step: Implementing Bonus Depreciation on Your 2025 Return

• Step 1: Order a completed cost segregation study for any property with $400K+ in value, or renovations over $60K
• Step 2: Confirm the IRS-classified components eligible for 5-, 7-, or 15-year recovery (Publication 946)
• Step 3: Calculate 60% of qualifying basis for bonus deduction — reflect this on Form 4562
• Step 4: Adjust for California by adding back bonus depreciation to your state return (CA Form 100/540 addback)
• Step 5: Review your estimated payment needs to avoid underpayment penalties
• Step 6: Track improvements placed in service each year and update your schedule annually

FAQ: Your Top 2025 Bonus Depreciation Questions

What types of property qualify for 2025 bonus depreciation?

For federal tax purposes, most tangible property with a recovery period of 20 years or less is eligible, including equipment, appliances, fixtures, parking lots, and land improvements. See IRS Publication 946 for details. Land and nonqualified real property are not eligible.

Do I need a cost segregation study for every rental?

Not always — but for properties over $400,000, or when major improvements are made, cost segregation is nearly always profitable, especially with 2025’s 60% bonus rate. For single-family rentals under $300,000, ask your strategist to run the numbers first.

Will using bonus depreciation increase my audit risk?

Claiming large bonus deductions is not a red flag if supported by a qualified cost segregation study and proper documentation. The IRS expects legitimate claims to be substantiated (see IRM 4.4.6). Keep all study reports and receipts in case of inquiry.

Troubleshooting: Avoiding Costly Errors with Bonus Depreciation Claims

Trap: Reclassifying assets without a professional study. Asset misclassification can trigger IRS recapture or denial. Always use a reputable provider with documented engineering-based methodology.

Myth: “Bonus depreciation is gone in 2025.” Not true — you get 60% this year, and phasing down continues through 2026. Don’t delay if you want the biggest write-off.

Pro Tip: If you buy, renovate, or expand a property late in the year, you can still capture bonus depreciation in 2025, even if the asset is in use for just one day — as long as it is placed in service before December 31st.
