More business owners are asking about real estate as a way to reduce taxes, especially real estate professional status and short-term rentals. The pitch is everywhere: buy a property, run a cost segregation study, take a large first-year loss against your business income. These strategies are real. They are also not always the right move, and in Palos Verdes tax planning conversations the question comes up more than almost anywhere else, because the people asking already own appreciated property and earn enough that the ordinary rules have stopped helping them.
Why this comes up so often in Palos Verdes tax planning
The typical profile on the hill is a business owner or high-earning professional with household income well past $300,000, a home that has appreciated for years, and friends or neighbors who own rentals. The instinct is reasonable: property has done well, and everyone says it is good for taxes. The problem is that the benefit most people picture, a rental loss offsetting business or salary income, is exactly what the passive-activity rules were written to stop at higher incomes.
What the passive-loss rules actually do
A rental is a passive activity by default. A passive activity loss, the amount by which a rental's deductions exceed its income, can only offset other passive income. It cannot offset your business profit, salary or investment gains, with one narrow exception.
If you actively participate in the rental, you may deduct up to $25,000 of loss against other income. That allowance shrinks by half of every dollar your modified adjusted gross income exceeds $100,000, and it is gone at $150,000, per IRS Publication 925 for the 2025 tax year. For almost everyone reading this, the allowance is already zero.
A loss you cannot use is not lost. It carries forward, offsets passive income from any source in later years, and is released in full when you dispose of your entire interest in the activity to an unrelated party in a fully taxable sale. So a large first-year loss on a rental is often not a deduction this year. It is a deduction the year you sell.
The two ways around the limit, and what they cost
Two legitimate routes let a rental loss offset other income this year. Both are more work than the pitch suggests.
- Real estate professional status. You must spend more than 750 hours a year in real property businesses you materially participate in, and that work must be more than half of all the working hours you put in anywhere. Status alone is not enough: you must also materially participate in the rental itself, and each rental is tested on its own unless you elect to treat them as one activity. If you run a full-time business, the more-than-half test usually fails. On a joint return one spouse must meet the 750-hour and more-than-half tests alone, though both spouses' hours count toward material participation.
- Short-term rentals. When the average guest stay is 7 days or less, the property is not treated as a rental activity under these rules, so the loss can offset other income without professional status. The catch is material participation: you must meet one of the IRS tests, the simplest being more than 500 hours in the year. Hiring a manager does not rule you out, but it changes which tests you can meet.
Both routes turn a property into a second job. Cleaning turnovers, guest messages, repairs, and a record of your hours. The IRS accepts any reasonable proof, a calendar or a narrative summary will do, but it is the first thing examined if the return is questioned. All of that time comes out of the business that produces your income in the first place.
The California catch
California generally follows the federal passive-loss rules with one large exception. The state did not adopt the real estate professional provision. In the words of the Franchise Tax Board's Form 3801 instructions, for California purposes all rental activities are passive activities, and the federal election is inapplicable for California personal income tax.
Put plainly: a Palos Verdes couple who qualifies as real estate professionals can use a rental loss against business income on the federal return, while on the California return the same loss offsets only passive income. With no other passive income, it sits suspended. California also does not follow federal bonus depreciation, listed among the federal and state differences in the FTB depreciation instructions, so the state loss is usually much smaller to begin with. With state rates that reach 13.3%, the strategy delivers well under what the pitch implied. Anyone selling real estate professional status in California who does not mention this has not run a California return.
A worked example
Take an invented married couple with $600,000 of taxable income after every other deduction, filing jointly for the 2025 tax year. They buy a $1,500,000 rental with $400,000 down and, through a cost segregation study, produce a $180,000 first-year paper loss.
Without professional status, the $180,000 is suspended. Nothing changes on this year's return. If one spouse qualifies as a real estate professional and they materially participate in the rental, or if it is a short-term rental they materially run, the loss takes taxable income from $600,000 to $420,000. That spans the 35% and 32% brackets under the 2025 federal rate tables, so the regular federal tax falls by about $60,500, before any other interactions on the return. On the California side the professional-status route does not touch their business income, because the state treats the loss as passive regardless, and the state loss itself is smaller without bonus depreciation.
The simpler approach most people overlook
Instead of building a real estate strategy for the tax result, buy property that actually fits your life. Housing for a parent or an adult child can be a real rental with real tax treatment and a reason to exist beyond the return, provided they pay a fair rental price and use it as their main home. Otherwise their days there count as your personal use under IRS Publication 527 and the deductions shrink. If you naturally grow into real estate professional status over time, our team will use it. We do not recommend forcing it.
Before you commit, compare the property against your core business and simpler investments on expected return, risk, liquidity and the hours each demands. Our team has owned rental property and has seen the strategy work and not work. The pattern is consistent: when the only reason for a purchase is the deduction, slow down and run the numbers first. Do not spend real money just to save tax money.
A 1031 exchange, a cost segregation study, an S corporation election: each is a tool, not an answer. The planning is in what fits your timing, your cash, and how much complexity you want to carry. The details of how that works for property owners are on our page for real estate investors.
Where real estate fits in a Palos Verdes tax plan
Real estate can be a powerful part of a plan. It should support the plan, not drive it. For most business owners doing tax planning in Palos Verdes, the larger and simpler levers sit inside the business: entity structure, owner compensation, the pass-through entity election, retirement design and the timing of income across years. Property earns its place when it fits your life and your cash, with the tax benefit as the bonus rather than the reason. If you are weighing a purchase mainly for tax reasons, Schedule a tax planning consultation and we will run your actual numbers before you move forward.
