Cost Segregation for Real Estate Investors and Landlords

While real estate tax strategies can seem intimidating and complex, they are a powerful way for real estate investors to boost their tax savings and cash flow. One strategy that seems complicated on paper (but doesn’t have to be) is cost segregation for real estate.

Cost segregation involves breaking down the components of your property into smaller parts and depreciating them separately on different timelines, rather than depreciating the entire property on a single timeline. With the way the US tax system works, cost segregation can save investment property owners an enormous amount on their taxes, especially with bonus depreciation, which has been around since 2017.

Understanding how to break down your property and depreciate it on different timelines may seem daunting and complex. But with the right tools, it’s a relatively painless way to save thousands (or more) on your next tax return. This article explains what cost segregation is and offers simple ways for owners to obtain and account for cost segregation studies.

First, a Brief Explainer on Depreciation

To understand cost segregation, you must first understand depreciation. Depreciation is a tax rule that allows property owners to deduct the cost of an income-producing asset over its useful life. It assumes that assets – things like sidewalks, light fixtures, roofs, etc – lose value over time. The IRS allows you to deduct that lost value as a cost of doing business that counts against your income taxes like any other business expense.

The depreciation deduction amount is calculated based on a pre-set timeline for different asset types, where the total cost of an asset is deducted over a certain number of years. For properties as a whole, the IRS sets the depreciation timeline at 27.5 years for residential and 39 years for commercial.

Suppose you own a $1 million rental property and use standard depreciation for the entire property. In that case, you can deduct $36,364 in depreciation expenses annually for 27.5 years, which reduces taxable income and increases cash flow. To find that value, just divide $1,000,000 by 27.5.

However, with cost segregation, you can deduct a significantly larger amount much sooner after purchasing a property, because you’ll depreciate individual property components over shorter timelines. Here’s how.

What is cost segregation in real estate?

Cost segregation is an analysis that breaks down the components of an investment property into various assets. Each asset is assigned a different depreciation timeline based on applicable tax codes, rather than a single 27.5-year depreciation timeline for the entire residential property as defined by the IRS.

Assets are either reclassified into shorter depreciation periods of 5, 7, or 15 years or remain at the standard 27.5-year period. These shorter depreciation periods are called ‘accelerated depreciation.’

Structural components like the roof and foundation typically fall under the standard depreciation schedule. However, land improvements such as sidewalks and fences depreciate over 15 years. Personal property, including appliances and flooring, depreciates in 5 or 7 years.

Cost segregation allows property owners to front-load their depreciation deductions for items that depreciate faster than the standard 27.5 years. Owners can realize significant tax savings earlier in the property’s life. Sound too good to be true? It’s not.

It’s a legitimate tax strategy that is officially recognized and supported by the IRS. On top of that, the government now allows for bonus depreciation, which permits you to deduct significantly more upfront to free up cash.

How Bonus Depreciation Supersizes Your Tax Savings

Introduced in the Tax Cuts and Jobs Act (TCJA) of 2017, bonus depreciation made cost segregation much more lucrative by enabling owners to depreciate 100% of the cost of certain assets in the year after purchasing a property. Under the TCJA, any property component that has a depreciation timeline of less than 20 years qualifies for 100% bonus depreciation. With bonus depreciation, the full cost of land improvements and personal property is deductible in the first year.

There was a planned phasedown of bonus depreciation, where it decreased to 80% for 2023, 60% for 2024, and continued phasing out until it returned to 0% in 2027, reverting to the original cost segregation timelines. However, the One Big Beautiful Bill Act (OBBBA), signed on July 4th, 2025, made 100% bonus depreciation for qualified property permanent. For the foreseeable future, the enormous upfront tax savings of bonus depreciation are here to stay.

A Cost Segregation Real Estate Example

Here’s a simple example to show the difference a cost segregation study can make for a residential rental property. We’ll go one step further to show the difference that bonus depreciation makes as well.

In this example, let’s say the rental property is worth $1 million (for simplicity). We’ll also say that 15% or $150,000 of the property’s value is considered land improvements with a 15-year depreciation, and another 15% or $150,000 is personal property with a 5-year depreciation. A total of 30%, or $300,000 of the property’s value, is eligible for bonus depreciation in year one.

The table below shows the amounts you can deduct from normal depreciation, accelerated depreciation from cost segregation, and bonus depreciation for the $1 million residential rental property.

As you can see, bonus depreciation reduces taxes by far the most upfront, which is likely the best tax advantage for most real estate investors, given that they can use that money now rather than later. The tax savings can help them purchase more properties, which would also qualify for bonus depreciation, creating a tax savings flywheel effect.

Getting a Cost Segregation Study in Real Estate

To qualify for cost segregation and the bonus depreciation, you’ll need to get a cost segregation study done for your property. This study has historically involved an engineer or other qualified professional visiting the property, taking photos, and determining what qualifies as structure, land improvements, and personal property, then figuring out the specific depreciation timelines for each asset.

The traditional cost segregation study method can take weeks or months and typically costs between $5,000 and $15,000, or possibly much more, depending on the size of the property.

However, there are now AI-driven cost segregation study software providers, such as Segtax, which automate and speed up the process, eliminate the need to hire engineers, and significantly reduce the cost. For most residential properties, an automated study from a provider like Segtax will work just fine, and these types of studies are fully IRS-compliant.

Accounting for Cost Segregation in TurboTenant

Once you’ve obtained a cost segregation study report, it’s easy to enter the results into TurboTenant Accounting and see how much tax savings you’ve generated.

You simply create an asset account for each component of the property that your cost segregation study broke out. These components could be furniture, appliances, carpets, etc. Then you enter the depreciation period for each component, as stated in your cost segregation study.

After that, add an opening balance to establish the cost basis (i.e., total cost) of each asset, which should also follow the study. Then, enter the depreciation numbers based on the information in the study for each year. Keep in mind whether you’re taking advantage of bonus depreciation or going the standard route. You can enter the depreciation amounts for each year in advance, making it even easier over time.

Once that’s done, you’ll be able to see (or show your client) how much tax savings you’ll gain from cost segregation on that property over the next few decades.

Cost Segregation Unlocked and De-Mystified

Cost segregation is a powerful tax strategy for rental property owners, and bonus depreciation makes it even more valuable. You’d be hard-pressed to find another IRS-approved way to generate as much tax savings as cost segregation provides.

Still, many are deterred by the perceived complexity and high costs of cost segregation studies, as well as the difficulty in properly accounting for different depreciation rates on a tax return.

With automated cost segregation software and easy depreciation accounting with TurboTenant, rental property owners can enjoy the tax benefits of cost segregation that were previously out of reach for many smaller property owners. Accountants can use these tools to help more clients save on their taxes, giving them happier clients who are more likely to stick around year after year.
