Tax Deductions for Real Estate Investors in California

Tax Deductions for Real Estate Investors in California

California real estate investors face a uniquely challenging tax environment. California taxes capital gains at ordinary income rates (up to 13.3%), does not allow bonus depreciation, and has its own set of passive activity loss rules that differ from federal law in important ways. At the same time, California real estate investors have access to powerful federal deductions — depreciation, mortgage interest, operating expenses, and 1031 exchanges — that can dramatically reduce taxable income.

This guide covers the complete tax strategy for California real estate investors in 2026. For personalized strategy, see KDA's Real Estate Investors page.

Depreciation — Your Most Powerful Deduction

Depreciation is the single most powerful tax tool available to real estate investors. The IRS allows you to deduct the cost of a residential rental property over 27.5 years, and commercial property over 39 years. This means a $550,000 residential rental property generates $20,000 per year in depreciation deductions — even if the property is appreciating in value.

Cost segregation studies can accelerate depreciation by reclassifying components of a property (flooring, appliances, landscaping, electrical systems) into 5, 7, or 15-year property classes. For a $1 million property, a cost segregation study can generate $150,000-$250,000 in accelerated depreciation in the first year.

Rental Property Operating Expenses

All ordinary and necessary expenses to operate your rental property are deductible: mortgage interest, property taxes, insurance, property management fees, repairs and maintenance, utilities you pay, HOA dues, advertising costs, and professional fees (CPA, attorney, property manager). Travel to inspect or manage your rental properties is deductible at 70 cents per mile in 2026.

The distinction between repairs (deductible immediately) and improvements (capitalized and depreciated) is critical. Replacing a broken water heater is a repair — deductible in full in the year paid. Installing a new HVAC system is an improvement — capitalized and depreciated. The IRS's tangible property regulations provide detailed guidance; the FTB generally follows federal rules here.

1031 Exchange — Defer Capital Gains Indefinitely

A 1031 exchange allows you to sell an investment property and defer all capital gains taxes by reinvesting the proceeds into a like-kind replacement property. In California, where capital gains are taxed at ordinary income rates (up to 13.3% state + 20% federal + 3.8% NIIT = up to 37.1% combined), the 1031 exchange is one of the most valuable tools available to investors.

Key rules: you must identify the replacement property within 45 days of the sale, and close on the replacement within 180 days. The replacement property must be of equal or greater value. A qualified intermediary must hold the proceeds — you cannot touch the money.

California has a "clawback" provision: if you do a 1031 exchange out of California into another state, California will eventually tax the deferred gain when you sell the replacement property — even if you are no longer a California resident at that time. This is a critical planning issue for investors considering relocation.

Short-Term Rentals (Airbnb/VRBO) in California

Short-term rental income (properties rented for an average of 7 days or less) is treated differently from long-term rental income. If you provide substantial services (cleaning, concierge, daily linen service), the income may be treated as active business income rather than passive rental income — which changes how losses are handled.

California requires short-term rental operators to collect and remit Transient Occupancy Tax (TOT) in most jurisdictions. Los Angeles, San Francisco, and most Orange County cities have specific STR licensing requirements and TOT rates ranging from 10-15%. These TOT payments are not deductible as a business expense.

California-Specific Rules for Real Estate Investors

California taxes capital gains at ordinary income rates — there is no preferential long-term capital gains rate at the state level. A California investor in the top bracket pays 13.3% state tax on capital gains, on top of the federal 20% rate and 3.8% NIIT. Total capital gains tax on a California property sale can reach 37.1%.

Proposition 19 (effective February 2021) significantly changed property tax reassessment rules for inherited properties. Under Prop 19, children who inherit a parent's home can only exclude $1 million of assessed value from reassessment if they use it as their primary residence. This has major implications for estate planning involving California real estate.

Entity Structure for California Real Estate Investors

Most California real estate investors hold rental properties in LLCs for liability protection. Each property in a separate LLC limits liability exposure. The LLC is typically taxed as a disregarded entity (single-member) or partnership (multi-member), with income flowing through to the owners' personal returns.

For investors with significant rental income, a management company structure (an S Corp that manages the properties and charges management fees) can shift some income from passive to active and create SE tax savings. This is a sophisticated strategy that requires careful implementation. See KDA's Real Estate Investors page for how we structure these arrangements.
