5 Tax Planning Strategies for Real Estate Investors to Maximize Deductions

Recurring expenses like taxes may not immediately come to mind as your largest expense as a real estate investor, but for many investors, this is true. For those who own investment properties free and clear or have held the property for a long time, taxes can easily exceed the cost of maintenance and financing. The delta between an average investor and one who scales quickly often isn’t deal flow or market timing. It’s how aggressively they treat tax planning as a capital allocation tool. This post outlines five tax strategies that effective real estate investors regularly use to grow their portfolio.

Cost Segregation: Treating a Building as a Collection of Assets

Depreciation of a standard variety takes a residential property’s cost and divides it by 27.5, and a commercial property by 39. This even schedule treats a building like a single, solid asset, which it isn’t. A cost segregation study does the work to account for all the little parts the building’s constructed from (electrical systems, flooring, specialty plumbing, cabinetry), and the outside stuff that helps protect the building itself (land improvements like paved parking or fencing), and reclassifies them into 5-year, 7-year, or 15-year recovery periods under Modified Accelerated Cost Recovery System (MACRS).

A cost segregation study can reclassify 20% to 40% of a property’s depreciable basis into shorter-life asset categories, according to the Journal of Accountancy. Made-up example: on a $2 million building, that’s potentially $400,000 to $800,000 in deductions that would otherwise be spread over the course of 39 years, that could be moved into a 5 to 15-year window. That’s your cash flow benefit right there. But, be warned: the IRS requires engineering-based documentation on all these reclassifications, and audit risk for misordered deductions is real. Segtax and other firms make studies specifically designed to pass IRS audit techniques, and for good reason.

Bonus Depreciation and the Phase-Out Problem

The Tax Cuts and Jobs Act allowed 100% bonus depreciation on eligible short-life assets placed in service from 2017 through 2022. That percentage has been stepping down since, 80% in 2023, 60% in 2024, and continuing downward.

The window is closing, and the investors who benefit most from cost segregation are the ones who time capital improvements and acquisitions to capture the highest available bonus depreciation percentage in the year they put assets into service. A renovation completed this year at 60% bonus depreciation is meaningfully better than one completed next year at 40%. Plan your project timelines accordingly.

Catch-Up Depreciation Without Amended Returns

If you’ve owned a property for several years and never ran a cost segregation study, you haven’t permanently lost those deductions. IRS Form 3115, the Application for Change in Accounting Method, lets you claim all the missed accelerated depreciation from prior years as a single deduction in the current tax year. No amended returns required for each prior year.

This is one of the most underused strategies in real estate tax planning. An investor who bought a commercial building in 2018 and runs a cost segregation study today can take six years of catch-up depreciation in a single filing. The resulting paper loss can offset a significant amount of taxable income, depending on how passive loss rules apply to their situation.

Real Estate Professional Status and Passive Loss Rules

This is where a lot of situations where people are trying to save money on taxes end up going. The Passive Activity Loss rules hamstring your ability to use rental losses to offset W-2 income or business income. Depreciation "paper losses" are wonderful, as long as you can actually use them.

Entering Real Estate Professional Status changes the game. Doing so requires you to spend over 750 hours a year on real estate activities, and real estate must account for the majority of your time. If you enter this status your rental activities are no longer classified as passive, and you can directly offset ordinary income. For a high-earning spouse or high outside income investor, this can change the pre-tax game on real estate investments significantly.

The IRS rules for claiming this status are no joke. Log your hours in actual real time, and assuming most or all of your rental income came from another primary job, be prepared for the IRS to put your numbers on the white-glove treatment. This is the place that people who are deliberately not renting properties as a full-time job often find themselves.

Partial Asset Disposition During Renovations

If you bought an apartment building that needed a new roof, and you didn’t make a partial asset disposition election, you’d still be depreciating the old roof, even though you’d thrown it in a dumpster. Meanwhile, you’d be starting to depreciate the cost of installing a new roof on a different schedule. The same would be true for the HVAC unit or the wastewater treatment system that was replaced as part of the acquisition or improvement of a commercial property.

Putting it Together

Just reclassifying assets into a shorter life does a lot to increase current deductions, obviously. But the reclassification doesn’t happen without the audit trail of the cost segregation study. Bonus depreciation accelerates the deductions for those newly classified assets in the year that they are put in service. The real estate professional tax status makes it easier to take full advantage of the deductions that have been accelerated. Then the REPS determination makes it possible to apply them in the first place. With the right partners and a guide to show you the way, those changes and rulings don’t cost money; they create it.
