Property values across Tulare County have held up well even through years when coastal California markets wobbled. So it tends to catch new landlords off guard when their accountant tells them they can deduct a portion of their rental’s value every year — on the same return where they’re also reporting that the property is worth more than when they bought it. It isn’t a contradiction. It’s one of the most valuable, and most misunderstood, tools available to rental property owners, and it works exactly the same way whether your rental sits in Porterville, Visalia, or anywhere else in the state.
If “depreciation” has always been the word your accountant says right before your eyes glaze over, here’s the version that actually explains what’s happening.
The Basic Idea
Depreciation is the IRS’s way of acknowledging that a building wears down over time — roofs age, HVAC systems fail, plumbing degrades — even while the land underneath it and the surrounding market may be appreciating. Because of that physical decline, federal tax law lets you deduct a portion of your property’s cost every year as a “paper loss,” spread across a set number of years.
It’s a paper loss because no actual money leaves your pocket to generate it. You already paid for the property when you bought it. Depreciation just lets you recognize that cost gradually on your tax return instead of all at once, which reduces your taxable rental income — often enough that a property generating solid monthly cash flow shows very little taxable profit at all.
This is federal tax law, so the mechanics are identical no matter which state your rental sits in. What varies by state is everything else about owning rental property — California’s landlord-tenant rules, security deposit law, and eviction procedures, all of which we’ve covered elsewhere on this blog, including our overview of California landlord-tenant law.
Why Depreciation Exists
Picture a rental home you bought in Visalia for $340,000. The land isn’t wearing out. But the roof, the siding, the water heater, and the HVAC system all have a limited lifespan and will eventually need repair or replacement. Depreciation spreads the recognition of that physical wear evenly across the property’s assigned “useful life” under federal tax law.
For residential rental property, that useful life is 27.5 years, regardless of whether you own a single-family home, a duplex, or a small multifamily building.
Running the Numbers
Here’s the part that trips people up: you can only depreciate the value of the structure, not the land underneath it. Land doesn’t wear out, so it isn’t depreciable.
A simple example:
- You buy a rental home for $340,000.
- Tulare County assessor records show the land is worth $75,000 and the structure is worth $265,000.
- Divide $265,000 by 27.5, and you get $9,636 per year in depreciation you can deduct against your rental income — every year, for 27.5 years, without spending anything extra.
If that property brings in $23,000 a year in rent and you have $9,500 in real expenses (mortgage interest, insurance, property management, repairs), your taxable profit before depreciation looks like $13,500. Subtract the $9,636 depreciation deduction, and your taxable income drops to roughly $3,900 — a meaningful gap at tax time.
What Counts, and What Doesn’t
- Depreciable: the building structure, major capital improvements (a new roof, a full kitchen remodel, a room addition), and certain appliances or fixtures, sometimes on faster 5- or 15-year schedules.
- Not depreciable: the land itself, and routine repairs and maintenance, which get deducted in full the year you pay for them instead.
The distinction between a “repair” and an “improvement” matters here. Patching a section of roof after storm damage is a repair, deducted immediately. Replacing the whole roof is a capital improvement, depreciated over time. When you’re not sure which bucket something falls into, that’s worth a quick check with your CPA before filing.
Bonus Depreciation: A Recent, Significant Change
If you looked into bonus depreciation a couple of years ago and walked away thinking it wasn’t worth pursuing, it’s worth revisiting. Federal legislation passed in 2025 permanently restored 100% bonus depreciation for qualifying property acquired and placed in service after January 19, 2025 — reversing what had been a scheduled phase-down toward zero.
In practice, this means certain components identified through a “cost segregation” study — flooring, cabinetry, appliances, fencing, driveways — can often be fully deducted in the first year, rather than spread across decades. The building structure itself still depreciates on the standard 27.5-year schedule; bonus depreciation applies only to the shorter-lived components.
For a single rental home, a full cost segregation study may not be worth the expense. But for landlords building a portfolio across Porterville and Visalia, it’s worth asking a CPA experienced with real estate investors whether the math works in your favor. Because federal rules in this area have shifted more than once recently, always confirm the current percentage and eligibility rules before filing.
The Catch: Depreciation Recapture
Depreciation isn’t free money forever. When you eventually sell a rental property for more than its depreciated value, the IRS “recaptures” the depreciation you claimed and taxes it — generally up to 25%, separate from your regular capital gains tax.
Landlords who get used to the annual deduction sometimes forget there’s a bill waiting at the end. That doesn’t make depreciation a bad idea — the time value of money still favors taking the deduction now — but it does mean planning ahead for that eventual tax event, especially if you’re thinking about eventually selling into a strong Central Valley market. This is exactly the scenario where a 1031 exchange becomes relevant, letting you defer both the capital gains tax and the depreciation recapture by rolling proceeds into another investment property.
How This Fits Your Bigger Tax Picture
Depreciation works alongside the other deductions and strategies covered in our guides on how rental income is taxed and legal ways to reduce your rental income tax bill. If you’re newer to owning rental property, or thinking about buying an investment property in Tulare County, those two articles pair naturally with this one.
How California State Taxes Interact With Depreciation
Depreciation is a federal concept, but it doesn’t stop at the federal return. California generally starts its state income tax calculation from your federal adjusted gross income, so a depreciation deduction that lowers your federal taxable rental income flows through and lowers your California taxable income too. There are a handful of areas where California decouples from federal tax law on specific provisions, so this is worth confirming with your CPA each filing season rather than assuming last year’s treatment automatically carries forward — California doesn’t always adopt federal changes, including some depreciation-adjacent rules, on the same timeline as the IRS.
A Few Mistakes We See Often
A handful of patterns come up repeatedly with landlords who handle their own taxes:
- Depreciating the full purchase price, including the land, instead of separating out land value using assessor records or an appraisal. This isn’t allowed and can create problems in an audit.
- Mixing up repairs and capital improvements in their own records, which makes it much harder for a CPA to calculate an accurate depreciation basis years into ownership.
- Skipping depreciation entirely because it feels complicated, and paying more tax than necessary as a result — probably the single most common and most avoidable mistake.
- Not planning for recapture when eventually selling, and being caught off guard by a tax bill that could have been anticipated years in advance.
Keeping Good Records Along the Way
The accuracy of your depreciation calculation depends heavily on good documentation — exactly what you spent on repairs versus capital improvements, and when. This is one of the quieter advantages of working with a professional property manager: every maintenance invoice and capital improvement gets tracked as it happens, so your CPA isn’t reconstructing a year from memory and a folder of receipts every April.

The Takeaway
Depreciation rewards you simply for owning rental property, regardless of whether that property happens to be appreciating right now — which, across much of Tulare County, it likely is. It isn’t a loophole; it’s a deliberate part of the federal tax code, meant to encourage private investment in rental housing. The landlords who get the most out of it are the ones who understand it well enough to plan around it, rather than treating it as a mysterious number their accountant produces once a year.
