Let’s open with a question most real estate investors don’t ask but should:
Are you actually earning more, or are you just paying more in taxes because you haven’t set up your depreciation strategy right?
Now before you say, “Wait, I have depreciation on my Schedule E,” let me stop you right there. Just having depreciation on your tax return isn’t the same as maximizing it.
Depreciation is not a line item. It’s a strategic lever. When used right, it lets you legally keep more of your rental income while setting you up for smarter moves down the road especially when it comes time to sell or exchange.
But if you’re like most entrepreneurs with a growing real estate portfolio, your focus is on acquisitions, renovations, tenants, cash flow. Not on something that sounds like a dusty accounting rule from a 1970s IRS manual.
Totally fair. But this? This is the stuff that separates investors who survive from investors who scale.
Let’s pull the curtain back. Welcome to the full guide on depreciation for people who own more than one rental property and want to actually use that portfolio like the wealth-building tool it’s meant to be.
The Big Idea: Depreciation Is the IRS Letting You Write Off a Phantom Loss
Here’s the basic premise:
Buildings wear out over time. So the IRS lets you write off the cost of your property structure over time even if the market value is going up.
It’s kind of like getting a thank-you card from the IRS for owning something useful. Except instead of a card, it’s a deduction worth thousands every year. No confetti, but we’ll take it.
Let’s say you bought a rental house for $500,000.
Your tax preparer allocates $100,000 to the land and $400,000 to the structure. You get to depreciate that $400,000 over 27.5 years, using a system called MACRS.
That’s $14,545 in annual depreciation every year, reducing your rental income on paper without you spending a dollar.
Now imagine that across five or ten properties. You’re looking at tens of thousands in “paper losses” that legally reduce your real taxes.
Why this matters: Your rental income could be fully offset by depreciation, meaning you’re collecting rent, showing a loss, and still paying no tax on that income.
And that’s just the beginning.
Step 1: MACRS — The IRS’s Default Depreciation Language
Let’s translate the acronym that everyone fakes familiarity with:
MACRS = Modified Accelerated Cost Recovery System
This is the standard depreciation schedule that the IRS requires you to use unless you have a very specific reason not to.
For residential property, MACRS spreads out the depreciation over 27.5 years. For commercial property, it’s 39 years. You start depreciating the property the month it’s placed in service.
Key phrase: placed in service. That doesn’t mean “when you closed.” It means the moment your rental was available for tenants even if it sat vacant for a bit. Your Austin, Texas CPA or certified public accountant near you should help make this distinction crystal clear.
MACRS uses the mid-month convention, which means the IRS assumes you started using the property halfway through the month. So yes, you get a half-month of depreciation for the first month regardless of whether it was the 1st or the 28th.
Details matter. That’s why most real estate investors rely on a small business CPA in Austin or a tax professional near them to run depreciation schedules behind the scenes.
Step 2: Bonus Depreciation — A Fast Pass for Smart Investors
Let’s say you make improvements to a newly acquired rental property—think appliances, HVAC, carpets, or landscaping.
Some of these assets have a shorter life (5, 7, or 15 years), which means under MACRS, you’d depreciate them faster than the main structure. But if you qualify, you can accelerate that even further using bonus depreciation.
Bonus depreciation lets you deduct a huge chunk of certain assets up front, in the year you place them in service.
Until recently, that meant 100% deduction in year one. Starting in 2023, it’s being phased out (80% in 2023, 60% in 2024, 40% in 2025, and so on). But even at 40%, that’s still a huge deduction if you know what qualifies.
Let’s say you install a $20,000 HVAC system and some appliances for $10,000. That’s $30,000. With bonus depreciation at 60%, you’d deduct $18,000 this year, rather than over 15 or 20 years.
Your licensed CPA can walk you through exactly how this plays with your current income level, property goals, and depreciation schedules.
Step 3: Section 179 — Similar, But With a Few More Speed Bumps
Section 179 is like bonus depreciation’s cousin. Still useful, but a little more limited in application.
You can use Section 179 to deduct the cost of certain business-use assets in full during the year of purchase. But there are two catches:
- You can only deduct up to your business’s net income.
- There’s a spending cap (over $1M as of now, but still a limit).
Also, Section 179 is less commonly used in rental real estate because the IRS doesn’t always consider rentals to be “active trade or business” unless you’re also providing significant services (like a short-term rental or vacation property managed hands-on).
It’s not off the table, it just requires strategy. At Insogna, we review Section 179 opportunities for clients who hold properties under S Corps, LLCs, or who have parallel businesses that qualify.
Step 4: Cost Segregation — When You’re Ready to Play in the Big Leagues
Let’s pause. This is the big one.
If you own multiple properties, and you’ve never heard of cost segregation, buckle up.
A cost segregation study breaks your property down into component parts and categorizes them into different asset classes.
This lets you front-load deductions by accelerating the depreciation of non-structural elements like:
- Carpet and flooring
- Cabinets
- Lighting
- Landscaping
- Pavement and sidewalks
- Fixtures
Instead of depreciating your whole property over 27.5 years, a cost seg study might allow you to depreciate 30% to 40% of the value in just 5 to 15 years.
Let’s say you buy a $1.2M rental property. A cost seg might identify $400,000 of that as depreciable within the first five years. Combine that with bonus depreciation, and you might deduct up to $320,000 in year one.
That’s not a deduction. That’s a weapon.
Your Austin accounting firm should be helping you evaluate when cost segregation makes sense especially if you’ve had a high-income year or need to offset gains.
Step 5: Don’t Let Personal Use Kill Your Deductions
The IRS is not thrilled when you mix business and pleasure especially with depreciation.
If you use a rental property personally for more than 14 days per year, or more than 10% of the total rental days, your depreciation deduction could be partially or fully disallowed.
Example: You stay at your beach house 20 days a year and rent it out 120. You’ve hit 16.7% personal use. That exceeds the 10% limit, and boom, your depreciation gets prorated.
It also messes with your ability to deduct other expenses.
To avoid this, you need clear documentation: calendars, logs, and receipts. We build these into your workflow at Insogna so there’s no confusion at tax time.
Step 6: Track Your Basis Like Your Portfolio Depends On It (Because It Does)
Your basis is your property’s tax DNA.
It starts with the purchase price, then adjusts over time based on:
- Improvements (add to basis)
- Depreciation (subtract from basis)
- Insurance payouts
- Partial sales or dispositions
- Section 1031 exchanges
Your adjusted basis is what determines your gain or loss when you sell and what the IRS uses to calculate depreciation recapture (more on that next).
If you don’t track basis properly? You might overpay on taxes. Or worse, underpay and invite an audit.
Our team of certified general accountants and CPAs in Austin builds property-by-property basis schedules so clients can pull real-time tax positions at a glance.
Because guessing = paying.
Step 7: Recapture Is Real But There’s a Way Around It
Let’s talk about the part most people only discover after they sell:
Depreciation recapture.
The IRS lets you deduct depreciation over time, but when you sell, they want a piece of that back. It’s taxed at 25%, up to the amount of depreciation you claimed.
So if you took $200,000 in depreciation over 10 years, that’s up to $50,000 in depreciation recapture tax just sitting there, waiting for you at the closing table.
But there’s a strategy: Do a 1031 exchange, and both the capital gain and the recapture are deferred.
This is where we pull it all together: depreciation planning, basis tracking, exit strategy, and entity structure all connect.

Frequently Asked Questions
1. What is MACRS depreciation for rental properties?
It’s the IRS’s default method: depreciate the building (not land) over 27.5 years. That’s around $14K in annual deductions on a $400K structure. Multiply that by multiple properties, and you’re cutting taxes big time. Ask a certified public accountant near you to set it up right.
- Can I still use bonus depreciation in 2025?
Yes, at 40% this year. Bonus depreciation lets you deduct qualifying improvements (like appliances or HVAC) all at once instead of over decades. Still powerful, but fading. Check with a tax advisor near you to use it while you can.
3. What’s cost segregation, and is it worth it?
Yes, if you own multiple rentals. It lets you depreciate parts of the property faster like flooring and fixtures so you get bigger deductions early. A smart move your Austin accounting firm should walk you through.
4. What if I use my rental personally?
If you stay more than 14 days or 10% of rental days, you must prorate depreciation, and you may lose other deductions. Keep personal use limited and documented. Your tax preparer near you can help track it cleanly.
5. What’s depreciation recapture when I sell?
The IRS taxes the depreciation you claimed, usually at 25%. But you can defer it with a 1031 exchange. Plan your exit with a certified CPA near you so you’re not surprised at closing.
