Most real estate investors I meet in Greater Austin are focused on one thing: cash flow. How much will this property bring in each month? What is the cap rate? How quickly will it appreciate?

Those are all the right questions. But there is another number most investors never think to calculate — and it could be the most important one of all: how much of your income can this property legally protect from taxes?

I am Roshan Budhathoki, a licensed real estate broker based in Manor, TX, serving investors and homebuyers across the Greater Austin area. This post is about one of the most powerful — and most overlooked — tax strategies available to real estate investors today: 100% Bonus Depreciation combined with a Cost Segregation study.

Used correctly, this strategy can save a single investor over $100,000 in taxes in the first year of ownership. And thanks to recent federal legislation, it is now permanent.

What Is Depreciation in Real Estate — and Why Does It Matter?

When you own an investment property, the IRS allows you to treat the building as an asset that gradually "wears out" over time. That wear and tear creates a paper deduction called depreciation — a way to reduce your taxable income even though no money is actually leaving your pocket.

Here is how the standard schedule works:

• Residential rental property: depreciated over 27.5 years
• Commercial property: depreciated over 39 years

So if you purchase a $1,000,000 investment property, with $200,000 allocated to land (which cannot be depreciated) and $800,000 to the building, your standard first-year depreciation deduction would be roughly $29,090 ($800,000 ÷ 27.5 years).

At a 37% marginal tax rate, that produces about $10,763 in tax savings in year one.

That is helpful. But it is nowhere near what is possible.

What Is 100% Bonus Depreciation?

Not every component inside a building depreciates over 27.5 years. Under IRS rules, certain assets — things like appliances, flooring, cabinetry, landscaping, specific electrical and HVAC components, and other "short-lived" improvements — have a much shorter useful life of 5, 7, or 15 years.

Bonus Depreciation allows you to skip the multi-year schedule entirely and deduct the full cost of those short-lived assets in the very first year you place the property in service.

Until recently, Bonus Depreciation was being phased out under existing law and was scheduled to disappear entirely. But the One Big Beautiful Bill Act (OBBBA) reversed that — permanently restoring Bonus Depreciation to 100% for properties acquired from 2025 onward.

That is a big deal. It means that every rental property an investor purchases going forward is eligible for the full first-year deduction — not a reduced percentage, not a phase-out, but the full 100%.

What Is a Cost Segregation Study?

To take full advantage of Bonus Depreciation, you first need to identify which portions of your property qualify as short-lived assets. That is what a Cost Segregation study does.

A qualified engineer or tax professional analyzes your property and separates its components into the correct depreciation categories:

• The main structure (depreciated over 27.5 or 39 years)
• Land improvements such as parking, landscaping, and lighting (15 years)
• Personal property such as appliances, fixtures, and equipment (5–7 years)

Once those short-lived assets are identified, 100% Bonus Depreciation accelerates the full deduction into year one.

The Real Numbers: What This Looks Like on a $1 Million Property

Let's use a straightforward example.

You purchase a $1,000,000 investment property:

• $200,000 allocated to land (non-depreciable)
• $800,000 in depreciable assets

After a Cost Segregation study, the breakdown looks like this:

• $300,000 in short-lived assets (appliances, equipment, land improvements) → 100% Bonus Depreciation in year one
• $500,000 in the main structure → standard 27.5-year depreciation, producing ~$18,182 in year one

Total first-year depreciation: $318,182

At a 37% marginal tax rate, that translates to potential tax savings of up to $117,727 in a single year.

Compare that to the $10,763 you would get from standard straight-line depreciation alone. The difference is not incremental — it is transformational.

Who Qualifies to Use This Strategy?

The good news: Bonus Depreciation is not just for institutional investors or large real estate funds. Individual investors purchasing even a single rental property can use it. The key is understanding how the IRS classifies your income and your role.

All Investors

Any investor who owns income-producing property (not a primary residence) can claim depreciation. With a Cost Segregation study, short-lived assets can be fully depreciated using 100% Bonus Depreciation. These deductions primarily offset passive income — rental income, K-1 distributions from partnerships, or income from businesses you are not materially involved in. Unused losses carry forward indefinitely.

Note: This does not offset W-2 wages or stock market gains for most investors.

Active Participants

If you are actively involved in managing your rental — approving repairs, screening tenants, making decisions — the IRS may classify you as an "active participant."

• Household income under $100,000: You can apply up to $25,000 of passive losses against your ordinary income
• Household income $100,000–$150,000: That benefit phases out gradually
• Household income over $150,000: The offset against ordinary income is no longer available, though passive income is still reduced

Real Estate Professionals (REP)

If you or your spouse qualifies as a Real Estate Professional under IRS rules, Bonus Depreciation becomes even more powerful — it can offset not just passive income but wages and other active income as well.

To qualify as a Real Estate Professional, you must:

1. Spend at least 750 hours per year in real estate activities
2. Does real estate make up more than half of your total working hours

Many full-time agents, brokers, and investors already meet this threshold without realizing it.

Why This Matters for Austin Investors Right Now

Austin's real estate market in 2025 and 2026 has created a unique convergence. Prices in many suburbs have pulled back from their peak. Sellers are offering concessions. And inventory has grown in communities like Manor, Pflugerville, Georgetown, Hutto, and Round Rock — areas where entry-level investment properties can be found at price points that make the numbers work.

Combine that pricing environment with 100% Bonus Depreciation, and the first-year return profile on a well-purchased investment property changes dramatically.

Instead of waiting years for equity appreciation to generate a return, an investor can capture a significant tax benefit in the very first year — keeping more capital in their hands to reinvest, pay down debt, or acquire the next property.

What to Do Before You Buy

If you are considering purchasing an investment property in Austin or any of the surrounding communities, here are three steps to take before you close:

1. Talk to a CPA who specializes in real estate before you buy.

Not after. A tax strategy conversation needs to happen before the purchase so the cost segregation study can be commissioned at the right time and the deductions can be properly planned.

2. Understand your income classification.

The value of Bonus Depreciation depends heavily on whether your income is passive, active, or professional. Your CPA can help you determine which category applies and what level of tax savings is realistic for your situation.

3. Work with a broker who understands the investment side of the transaction.

Not just the listing. The right broker can help you identify properties with the right asset composition — higher percentages of short-lived components, which means more to accelerate through Bonus Depreciation — and structure the offer to reflect the true investment value.
