The Real Estate Tax Deduction Most High Earners Cannot Use

You have probably heard the pitch. Buy real estate, run a cost segregation study, take a large depreciation deduction, and wipe out the tax on your income. The deduction is real. For most high earners it also cannot be used against a salary, because of a rule written in 1986. This article walks through real estate tax strategy for high earners: how the deduction works, the two ways to use it, and where the bill comes due.

How depreciation and cost segregation create the deduction

When you buy a rental property, you deduct the cost of the building over time. Residential rentals are written off over 27.5 years and commercial property over 39. Land is not depreciable. On a $1 million duplex with $200,000 of land, that works out to about $29,000 a year.

A cost segregation study separates out the parts of the building with shorter tax lives, such as appliances, carpet, cabinetry, landscaping, and parking. Those components have lives of 5, 7, and 15 years. Bonus depreciation then lets you deduct property with a life of 20 years or less in the first year. The 2025 tax law made 100% bonus depreciation permanent for property acquired and placed in service after January 19, 2025.

Firms that perform these studies report moving 15% to 30% of a building's cost into short life property. In the middle of that range, the duplex produces roughly $160,000 of deduction in year one.

The passive activity loss rules

In 1986 Congress limited how these losses can be used. Rental real estate is passive by definition, and passive losses can only offset passive income. They cannot offset your salary, bonus, consulting income, interest, or dividends.

There is one exception. If you actively participate, you can deduct up to $25,000 of loss against other income. That allowance phases out between $100,000 and $150,000 of income, and those figures have never been indexed for inflation. For most high earners it is worth nothing.

Losses you cannot use are suspended and carry forward until you have passive income to absorb them or you sell the property in a fully taxable sale.

Two ways to use real estate losses against other income

Real estate professional status

If you qualify, your rentals stop being automatically passive. You need more than half of your working hours in real property businesses and more than 750 hours a year in them. The test applies per person, so spouses cannot combine hours. In practice this works when one spouse runs the real estate as an occupation.

You still have to materially participate in the properties, and you need a real log of your hours that you keep as you go. Reconstructed and estimated logs have lost in Tax Court.

Short term rentals

If the average guest stay is 7 days or less, the property is not treated as a rental activity, so the automatic passive rule does not apply. You still have to materially participate. For someone with a job, that usually means more than 100 hours of your own time and more than any other individual, including your cleaner.

Personal use matters too. If you use the property for more than the greater of 14 days or 10% of the days it was rented, it is treated as a residence and your deductions are capped at the rental income.

The exit: 1031 exchanges and the step up in basis

A 1031 exchange lets you sell a property, roll the proceeds into another, and defer the tax. You have 45 days to identify the replacement and 180 days to close, and you must use a qualified intermediary.

If you keep exchanging until death, your heirs receive the property with a basis equal to its value at that date, and the deferred gain and depreciation go away. That requires never selling for cash. It is an estate plan more than a liquidity plan.

If you have done a cost segregation study and plan to exchange, talk with your CPA before you close. A clean exchange can still produce ordinary income depending on how the components line up.

Where the bill comes due

• Recapture. Depreciation comes back when you sell. The building portion is taxed at up to 25%, and the short life components come back as ordinary income at rates up to 37%.
• Excess business loss limit. Even past the passive rules, a separate cap applies. For 2026 it is $256,000 for a single filer and $512,000 for a couple, with the excess carried forward.
• State rules. California does not follow federal bonus depreciation and does not recognize real estate professional status.
• Audit risk. The IRS maintains a dedicated audit guide for cost segregation studies, and taxpayers have historically lost most passive loss cases that reached court.

Cost segregation is a timing strategy. It accelerates deductions you would have received anyway. It tends to pay off when you exit through an exchange or a step up in basis, and it can lose if you sell for cash a few years later.

Who these strategies work for

They tend to work when one of these is true:

• You or your spouse can make real estate a full occupation, with the hours and records to show it.
• You run a short term rental yourself and follow the personal use rules.
• You already have passive income, or a passive gain coming, that the losses can absorb.
• You are building a portfolio you intend to exchange and eventually pass on.

They usually do not work if you have a demanding full time job and no spouse with the hours, if you need the money liquid in the next several years, or if you are buying a vacation home you plan to use. Real estate is an investment first and a tax strategy second. A mediocre property with an excellent deduction is still a mediocre property.

Common questions

Can I use rental losses to offset my W2 income?

Usually not. Rental losses are passive and can only offset passive income, unless you qualify as a real estate professional or the property meets the short term rental rules and you materially participate.

Is a cost segregation study worth it?

It depends on whether you can use the deduction and how you plan to exit. If the losses will sit suspended, or you expect to sell for cash in a few years, the benefit is much smaller.

What is the short term rental tax loophole?

When the average stay is 7 days or less, the property is not treated as a rental activity under the passive loss rules. If you also materially participate, the losses can offset other income.

You have heard some version of this. Buy real estate, do a cost segregation study, take a giant depreciation deduction, and wipe out the tax on your income. It sounds like the thing wealthy people know that you do not.

Here is what almost nobody tells you first. For most high earners, that deduction is completely unusable. Not reduced. Unusable. A rule written into the tax code in 1986 blocks it, and the one exception for regular investors phases out entirely at one hundred and fifty thousand dollars of income. That number has never been adjusted for inflation in forty years, so if you are the person these strategies get marketed to, you are already above it.

The deduction is real. Getting to use it is the entire game. In the next fifteen minutes I will walk through what actually works, how each strategy functions in plain English, and what it costs you. And I will answer the question directly. Is there a free lunch anywhere in real estate? There is not, and I will show you exactly where the bill arrives.

Who I am and what we will cover

Quick introduction. I am Andy VandenBerg, founder of VDB Wealth, where I work with business owners, executives, and families who have genuinely complicated financial lives. A large part of my job is telling people whether a strategy actually fits them, which often means talking them out of something that sounded great in a webinar.

Here is the plan. The engine, which is depreciation and cost segregation, and why it produces such large deductions. The wall that stops most people from using them. The only two real ways through that wall. The passive options, meaning syndications, Delaware statutory trusts, and opportunity zones. The exit, including ten thirty one exchanges and what happens at death. And finally, where the bill comes due, because it always does.

The engine: depreciation and cost segregation

Let us start with why real estate produces deductions at all.

When you buy a rental property, the tax code lets you deduct the cost of the building over time, on the theory that it wears out. Residential rental property is written off over twenty seven and a half years. Commercial is thirty nine. Land is never depreciable, because land does not wear out.

So on a one million dollar duplex where the land is worth two hundred thousand, you are depreciating eight hundred thousand over twenty seven and a half years. That is about twenty nine thousand dollars a year of deductions. Useful, but not dramatic.

Cost segregation is what makes it dramatic. A qualified engineer studies the building and separates out everything that is not really the structure. Appliances, carpet, cabinetry, specialty electrical, landscaping, fencing, parking. Those components have much shorter tax lives, five, seven, and fifteen years, instead of twenty seven and a half.

That matters because of a second rule. Bonus depreciation lets you deduct the entire cost of property with a tax life of twenty years or less in the first year, and the 2025 tax law made one hundred percent bonus depreciation permanent again for property acquired and placed in service after January nineteenth of 2025. Note the date, because if you bought before then, you are on the old phase down schedule, which is only twenty percent this year.

Put the two together. The firms that perform these studies report reclassifying somewhere between fifteen and thirty percent of a building's cost into short life property, depending on the property type. Take the middle of that range on our duplex and you are looking at roughly one hundred and sixty thousand dollars of deduction in year one, instead of twenty nine thousand.

That is the engine, and it is completely legitimate. Here is the part that gets skipped.

The wall most people never hear about

In 1986, Congress got tired of high earners using real estate losses to erase their salaries, so they built a wall. The rule is called the passive activity loss limitation, and it says two things.

First, rental real estate is automatically passive. Not usually passive. Automatically, by definition, no matter how involved you are.

Second, passive losses can only offset passive income. They cannot offset your salary, your bonus, your consulting income, or your interest and dividends.

There is one exception. If you actively participate in your rentals, you can deduct up to twenty five thousand dollars of loss against other income. But that allowance shrinks by fifty cents for every dollar your income exceeds one hundred thousand, and it is gone completely at one hundred and fifty thousand. Those figures were written in 1986 and never indexed for inflation. For essentially everyone watching this, that exception is worth zero.

So walk back through our duplex. You generated one hundred and sixty thousand dollars of deductions. If your income is a salary, you can use none of it this year. The loss is suspended and carries forward indefinitely, waiting until you either have passive income to absorb it or you sell the property in a fully taxable sale, which releases it.

That is the honest version. The deduction is real. Whether it is usable depends entirely on what kind of income you have, and the marketing never leads with that.

The only two ways through the wall

There are exactly two doors through that wall, and both of them are doors of effort, not paperwork.

Door one is real estate professional status. If you qualify, your rentals stop being automatically passive. It takes two things in the same year. More than half of all the personal services you perform in any trade or business have to be in real property businesses, and you need more than seven hundred and fifty hours in those businesses.

Read that first test again, because it ends the conversation for most people. If you work a full time job of two thousand hours, you would need more than two thousand hours in real estate to clear it. And this is tested per person, not per couple. You cannot add your hours to your spouse's. One of you has to clear both tests alone.

So in practice this is a household strategy. One spouse works, the other genuinely runs the real estate as their occupation. That can absolutely work, and I have clients where it does. But it is a job, not a loophole.

There is also a second layer people miss. Qualifying as a real estate professional only removes the automatic passive label. You still have to materially participate in the properties themselves, which is its own set of tests.

And documentation is where these cases die. In a Tax Court decision from December of 2025, a married couple, both attorneys, one with a masters in taxation and a CPA credential, lost because the activity log used standardized blocks of time, seven hours for every cleaning regardless of what actually happened. The court called it a ballpark guesstimate. In another case, the taxpayers reconstructed their hours years later during the litigation itself. They lost too. If your deduction depends on a log, the log has to be real and kept as you go.

Door two is short term rentals, and this one is more accessible. If the average guest stay across the year is seven days or less, the property is not treated as a rental activity at all. And if it is not a rental activity, the automatic passive rule does not apply, so you do not need real estate professional status.

But you still have to materially participate, and this is where most short term rental plans quietly fail. The realistic test for someone with a job requires more than one hundred hours of your own participation and, critically, more than any other single individual involved. That includes your cleaner. Thirty turnovers at four hours each is one hundred and twenty hours for your cleaner alone. If you did one hundred and ten, you lose.

One more trap that ends this instantly. If your personal use exceeds the greater of fourteen days or ten percent of the days it was rented, the property is treated as a residence, your deductions get capped at the rental income, and the strategy is off the table for that year. So the beach house you use for three weeks every summer does not work. That is not a technicality. That is the design.

The exit: exchanges and the step up

Now the exit, because everything above is only half the story until you know how you get out.

The classic tool is a 1031 exchange. Sell a property, roll the proceeds into another one, and defer the tax. The rules are strict and they do not bend. Forty five days from closing to formally identify the replacement property, one hundred and eighty days to close, and you have to use a qualified intermediary. You cannot touch the money. Miss either date and the whole thing is a taxable sale.

Chain enough of those together and you get what people call swap until you drop. You keep exchanging, you never pay the tax, and when you die your heirs receive the property with a basis equal to its value at that date. The deferred gain and all the depreciation you took disappear.

That is not a trick. It is real, and it is the actual endgame behind most serious real estate wealth. But be clear about what it requires. You have to never sell for cash. It is an estate plan, not a liquidity plan.

And one trap worth naming. You can do a clean exchange, take no cash out at all, and still owe ordinary income tax, because of how the components from your cost segregation study line up against the components of the property you bought. If you have done a study and you are exchanging, that is a conversation to have before you close, not after.

Where the bill comes due

So, is there a free lunch here? No. Here is where the bill arrives.

Start with recapture. Every dollar of depreciation you took reduces your basis, so it comes back when you sell. The portion tied to the building is taxed at a rate up to twenty five percent, higher than the twenty percent long term capital gains rate. And the portion tied to all those short life components from your cost segregation study comes back as ordinary income, at rates up to thirty seven percent. Add the three point eight percent investment income surtax and your state on top.

Sit with that. Cost segregation does not create deductions out of nowhere. It accelerates deductions you were going to get anyway, and in exchange it converts part of a future twenty five percent bill into a future thirty seven percent bill. It is a timing strategy. It wins when the time value of money works in your favor and when you exit through an exchange or a step up in basis. It can lose if you sell for cash a few years later at the same tax rate.

Second, there is a wall behind the wall. Even if you get through the passive rules, a separate limit caps how much business loss you can use against other income in one year. For 2026 that is two hundred and fifty six thousand dollars for a single filer and five hundred and twelve thousand for a couple, with the excess carried forward.

Third, your state may not play along. California does not follow federal bonus depreciation at all, and does not recognize real estate professional status at all. So a Californian can do everything right, get a large federal deduction, and get essentially nothing at the state level, while keeping two separate sets of depreciation records for the life of the property.

And fourth, this is enforcement heavy territory. The IRS maintains a dedicated audit guide for cost segregation studies, and that guide admits there is no bright line test for classifying these components. The last time anyone systematically counted the litigation, in a Taxpayer Advocate report covering cases through 2014, the IRS won outright in over eighty percent of passive activity loss cases. Even taxpayers with representation lost most of the time. These are winnable positions. They are not casual ones.

So who does this actually work for

So let me make this practical.

These strategies genuinely work when one of a few things is true. You or your spouse can realistically make real estate a full occupation, with the hours and the records to prove it. Or you run a short term rental yourself and you are honest about the personal use rules. Or you already have passive income, or a passive gain coming, that these losses can absorb. Or you are building a long term portfolio you intend to exchange and eventually pass on, where the deferral becomes permanent.

They usually do not work if you have a demanding full time job and no spouse with the hours, if you need the money liquid in the next several years, if you are buying a vacation property you plan to actually use, or if you live in a state that will not follow the federal treatment.

And one more thing worth saying plainly. Real estate is an investment first and a tax strategy second. A mediocre property with an excellent deduction is still a mediocre property. I have watched people buy the wrong building for the right tax reason. It is an expensive way to save on taxes.

Call to action and close

To wrap up. The deductions are real and large. The rules governing whether you can use them are strict, decades old, and written specifically to stop high earners from doing what these strategies promise. There are two honest ways through, both of which require real work, and every path ends with a recapture bill unless you exchange or hold to the end.
