Take Advantage of 100% Bonus Depreciation While You Still Can

Depreciation is the relatively simple fundamental concept that as new things incur wear and tear, they become worth less and less over time.

That seems straightforward. But of course leave it to the IRS to write rules and regulations to try to pin down exactly how different classes of items depreciate — and from a tax perspective only, as opposed to an overall market value standpoint.

Understanding this concept may seem arcane, but depreciation can be a powerful tax tool that can markedly improve the returns of certain investments.

Today, we’ll look at how the depreciation benefit has recently been juiced — and how you can benefit from it, if only for a limited amount of time still.

This post from Dr. Jim Dahle was first published on The White Coat Investor.


What Is Depreciation?



Depreciation is a tax break available to any business owner who buys property (all property, not just real estate) that isn’t used up in a single year.

If you buy a laptop for your online survey-taking business, you can’t just write off the whole cost of the computer as a business expense in year 1 (actually, you now can, but more on that later). You have to depreciate it over its useful life span, taking some of the cost as a business expense in each year until its useful life span is over.

Since the life span of any given piece of property can be difficult to determine a priori, the IRS has provided some guidance. This guidance is called the Modified Accelerated Cost Recovery System (MACRS) and is found in IRS Publication 946, Appendix B. The actual table is long and complicated, but here is a useful summary:

depreciation schedule


As you can see, you can depreciate some things very quickly (only five years for a computer), but some things must be depreciated over a much longer period of time (rental property). Remember that with rental property you only get to depreciate the structure, not the land.

As a general rule, depreciating something faster is a good thing, because you get your tax break much sooner. But if you use up all your tax breaks early on, you obviously won’t have them later too, so there are some situations where you would rather get the break later (especially if expect to be in a higher bracket later).


Methods of Depreciation


The basic formula for depreciation is to take the value of the asset, subtract out its “salvage value,” and then divide the rest by its useful life.


Straight Line Depreciation

There are multiple methods of depreciation. The easiest to understand is “straight line” depreciation. With that method, you basically take the purchase price of the depreciable property (let’s say you bought a rental house for $150,000 and determine the land is worth $30,000 and the salvage value of the building after 27.5 years is $20,000) and you divide it by 27.5 years.

=$100,000/27.5 years = $3,636.


Every year, you get to reduce the income from that property by $3,636 on your taxes. Cool, right? If your marginal tax rate on that type of income is 45.8% (37% federal, 5% state, 3.8% PPACA tax) like mine, that deduction is worth

$3,636 * 45.8% = $1,665

in cold hard cash in my pocket. This assumes, of course, that I actually had at least $3,636 in Rental Income above and beyond my other expenses, but if I didn’t, I can at least carry that depreciation forward.


Accelerated Depreciation

There are at least three other methods of depreciation, generally called “accelerated depreciation.” They are called

  1. Double declining depreciation,
  2. Sum of the year’s digits depreciation, and
  3. Unit of production depreciation.

The goal with each of these is to simply get more depreciation up front rather than spreading it out evenly over the entire time period. In exchange for a little more work (or more likely, paying a little more to your accountant), you pay less in tax in the first few years. While explaining each of these methods is way beyond the scope of this article, you can increase your first year’s depreciation deduction by almost 100% by using these methods.


Alternative Depreciation System

There is also an Alternative Depreciation System, which basically takes LONGER than straight-line depreciation to depreciate property. One might use that if they prefer to get that deduction later due to being in a higher tax bracket then (or just to better match income to depreciation—remember it doesn’t do any good to get regular depreciation upfront if you don’t have enough income to use it).

By the way, I do my own taxes, including a relatively basic corporate tax return and a dozen K-1s, but if I was still investing directly in rental properties, I would have started paying an accountant long ago to do my taxes, primarily due to the complexity of the depreciation rules. This stuff is complicated!



Yes, depreciation really is this awesome.

Why Is Depreciation Awesome?


There are basically four sources of return from a rental property:

  1. Income (rent)
  2. Appreciation of the property
  3. Mortgage paydown
  4. Tax breaks

Depreciation obviously falls into the fourth category. In fact, it is really the entire fourth category in most cases. Yes, you can write off all your legitimate expenses like insurance and property management fees, but that money is actually gone. That’s actually true with depreciation too.

Computers, appliances, and buildings really do wear out and really do have to be replaced. Depreciation just recognizes that fact.

However, depreciation differs from the rest in that it is recaptured at a lower rate when you sell. So perhaps you took a deduction that was worth 37% federal, but then only paid 25% federal when it was recaptured.

Not only is there an arbitrage between rates there, but there is a time value of money. You got to use those saved taxes for up to 39 years before paying them. In addition, if you exchange the property (instead of selling it) over and over again between now and the end of your life and your heirs get the step up in basis at death, that depreciation may never be recaptured.


3 Ways Depreciation Saves Money

  1. Arbitrage between tax saved and tax recaptured
  2. Earnings on tax savings between deduction and recapture
  3. 1031 Exchanges further deferring or even eliminating depreciation recapture


What Is New with Depreciation?


Now that we’ve got the basics of depreciation out of the way, let’s talk for a few minutes about why depreciation is even better now than it was in 2013 when I wrote that first article. These changes primarily come down to the Tax Cuts and Jobs Act (TCJA) implemented in 2018. To understand them, however, we have to introduce some new types of depreciation.


Bonus Depreciation


In 2002, Congress introduced Bonus Depreciation with the Job Creation and Worker Assistance Act. This was basically a way to stimulate small business growth by giving small businesses a little extra tax cut. Instead of having to divide the depreciation deduction over the entire useful life of the property, you got to take a 30% depreciation in year 1, and then divide the rest over the useful life. In 2003, the Bonus Depreciation percentage was first increased to 50%. With the TCJA, that percentage was increased to 100%.


An additional change is that you can now buy USED property (as long as you haven’t used it before) and depreciate it in the same way as you would a brand new property, as specified under previous law. Those changes are set to expire in 2023 unless Congress acts again.

So what types of property are eligible for bonus depreciation?

  • Property depreciated under the Modified Accelerated Cost Recovery System (MACRS) that has a recovery period of 20 years or less (generally, tangible personal property),
  • Certain computer software,
  • Water utility property,
  • Qualified film or television productions,
  • Qualified live theatrical productions, and
  • Specified plants.

Since rental property (whether residential or non-residential) has a recovery period of more than 20 years, it does not qualify for bonus depreciation.

However, bonus depreciation is even better than regular depreciation. There is no maximum deduction, no phase-out, and no rule about taxable income—so you can create a taxable loss using bonus depreciation rather than having to carry forward the depreciation. Maximum vehicle depreciation amounts were also increased by the TJCA (up to $18,000 in year 1).

[PoF: Note that 100% bonus depreciation will be phased out after 2022, with the maximum first-year deprecation as follows:]

  • 2022 = 100%
  • 2023 = 80%
  • 2024 = 60%
  • 2025 = 40%
  • 2026 = 20%
  • 2027 = 0%



Section 179 Depreciation


At the risk of totally losing you, I’m going to tell you about one more type of depreciation, Section 179 Depreciation. Like Bonus Depreciation, Section 179 Depreciation is taken all in year 1 rather than over the useful life of the property. It used to be limited to about $500,000 and reduced dollar for dollar by amounts over about $2 million. Those limits were increased to $1 million and $2.5 million, respectively, and indexed to inflation. So what qualifies for Section 179 Depreciation? Here are the rules:

  1. Tangible
  2. Purchased (see below for a possible exception)
  3. Used >50% for business
  4. Placed in service in this tax year
  5. Acquired from an unrelated party.

It includes:

    • Equipment
    • Business vehicles weighing more than 6,000 pounds
    • Computers
    • Software
    • Office furniture
    • Office equipment
    • Some building improvements—fire suppression, alarm systems, HVAC, roofing
  • Any improvement to a building’s interior that does not enlarge the building, change the framework, or include an escalator or elevator


It still does not include rental property or intangibles (like patents or trademarks), but all of those building improvements are new 179 depreciation eligible expenses since the TJCA passed.


Alternative Depreciation System

If for some bonkers reason you were using the Alternative Depreciation System, the TCJA decreased the amount of time for depreciating residential rental property from 40 years to 30 years.


What Is the Deal with Leased Property and Section 179?


There are all kinds of companies on the internet that want to lease you equipment and tell you that you actually CAN take a 179 deduction for it despite the fact that you don’t own it. Here’s what the IRS has to say about that:

“You can depreciate leased property only if you retain the incidents of ownership in the property (explained below). This means you bear the burden of exhaustion of the capital investment in the property. Therefore, if you lease property from someone to use in your trade or business or for the production of income, you generally cannot depreciate its cost because you do not retain the incidents of ownership. You can, however, depreciate any capital improvements you make to the property.

If you lease property to someone, you generally can depreciate its cost even if the lessee (the person leasing from you) has agreed to preserve, replace, renew, and maintain the property. However, if the lease provides that the lessee is to maintain the property and return to you the same property or its equivalent in value at the expiration of the lease in as good condition and value as when leased, you cannot depreciate the cost of the property.

Incidents of ownership.

Incidents of ownership in property include the following.

  • The legal title to the property.
  • The legal obligation to pay for the property.
  • The responsibility to pay maintenance and operating expenses.
  • The duty to pay any taxes on the property.
  • The risk of loss if the property is destroyed, condemned, or diminished in value through obsolescence or exhaustion.”

As you can see, that lease agreement is going to have to be pretty unique to meet those requirements. But there are companies that will help you write a lease this way, such that your tax deduction can be greater than your lease payments.


Personal Examples of Depreciation


Just to give you an idea of how powerful a tax deduction depreciation can be, let me use the information from three of my K-1s from 2018.

The first is a syndicated apartment complex I bought a piece of for $100,000. It did OK, slightly below pro-forma for the year, paying me $3,815 in income from the portion of 2018 during which I owned it. My income from the property on Line 2 of my K-1 was -$36,225. That’s right, a loss of over $30,000. Now I’m not sure which method of depreciation they used, but it’s going to be quite a few years before I pay any taxes on any income from that property.

The second is another syndicated apartment complex I bought a piece of several years ago for $10,000. In 2018, it paid me an income of $503. Not awesome (it’s actually underperforming pro-forma) but not terrible. On line 2, the K-1 listed -$638. That’s right. Tax-free income, at least until depreciation recapture after it is sold.

The third is a private real estate fund. When I wrote this post in 2020, this one actually hadn’t sent me any income as it was still being invested. My commitment was $100,000, even though I didn’t yet have it all invested. In 2017, my K-1 line 2 was -$3,869. In 2018, it was -$4,327. As it pays out income over the life of the investments, it’s going to be covered entirely by depreciation, at least for a few years.

My bond income is fully taxed at my ordinary tax rates (except muni bonds). My stock income is taxed at qualified dividend rates. But my real estate income isn’t taxed at all, at least for now. That’s the power of depreciation, and it’s a big deal in my tax bracket (and probably yours).

If you’re interested in learning more about real estate investments like mine, check out our real estate partner page for some introductions.

Either way, all of that explains why depreciation is an even better deduction than it used to be.

  1. Thanks for this detailed and informative article on depreciation.

    I learned something new, in that recaptured depreciation is taxed at 25%.
