Most business owners have heard they can write off equipment fast, but very few actually understand how the bonus rules work as the percentages phase down. That confusion is expensive. In 2024, the bonus rate dropped again, and without a clear **bonus depreciation example 2024** that matches your situation, you are guessing about some of the biggest deductions on your return.

Quick Answer

For the 2024 tax year, most new or used qualifying business assets with a recovery period of 20 years or less can still qualify for bonus under Internal Revenue Code Section 168(k), but only 60 percent of the cost is immediately deductible. The remaining 40 percent is recovered over time using standard MACRS rules. Smart planning around purchase timing, asset type, and entity structure can easily swing your tax bill by tens of thousands of dollars.

How Bonus Depreciation Works After Recent Law Changes

Bonus is an additional first year deduction layered on top of the normal Modified Accelerated Cost Recovery System, or MACRS, which is the standard way the IRS lets you recover the cost of business property over time. Under Section 168(k), certain property placed in service during the year is eligible for an immediate write off of a percentage of the cost. That percentage used to be 100 percent, but starting in 2023 it began phasing down by 20 points per year.

The Current Phase Down Schedule

• 2023: 80 percent bonus
• 2024: 60 percent bonus
• 2025: 40 percent bonus
• 2026: 20 percent bonus
• 2027 and later: Scheduled to drop to zero unless Congress acts

To qualify, property generally must have a recovery period of 20 years or less under MACRS. That covers most equipment, computers, furniture, machinery, and certain internal improvements. It also covers some land improvements like parking lots and fences. The IRS goes into more detail in Publication 946, which explains how to depreciate property.

How Bonus Interacts With Section 179

Business owners usually have three levers for cost recovery on big purchases:

• Section 179 expensing
• Bonus under Section 168(k)
• Regular MACRS over the normal life of the asset

Section 179 lets you choose an amount of qualifying property to expense up to a yearly limit, phased out for very large purchases. Bonus, in contrast, is automatic for qualifying property unless you elect out for a specific class of property. For many small and mid sized California business owners, the art is deciding how much to push through 179, how much to leave for bonus, and how much to stretch out to future years for smoother taxable income.

Strategic decisions here are at the heart of good tax planning services. A one size approach rarely works, especially if your income is volatile or you expect to sell the business or assets within a few years.

A Straightforward Bonus Depreciation Example 2024 for a California LLC

It helps to walk through numbers. Assume Maria owns a California single member LLC treated as a disregarded entity. She installs a new manufacturing line in July 2024 that costs $400,000. The equipment has a 7 year MACRS life, so it qualifies for bonus.

Scenario 1: Use 60 Percent Bonus in 2024

Under 2024 rules, the default treatment is:

• Bonus portion: 60 percent of $400,000 = $240,000 immediate deduction
• Remaining basis: $400,000 minus $240,000 = $160,000
• First year MACRS on remaining basis (7 year, half year convention) roughly 14.29 percent
• MACRS deduction: 14.29 percent of $160,000 ≈ $22,864

Total 2024 deduction is about $262,864. If Maria is in a combined federal and California effective marginal rate of 35 percent, the immediate tax reduction is roughly $92,000. Cash tax outlay is lower now, but future years will have smaller deductions.

Scenario 2: Elect Out of Bonus and Use Only MACRS

If Maria elects out of bonus for the appropriate class of property, she would instead depreciate the full $400,000 over 7 years using MACRS. First year depreciation under the same 14.29 percent rate would be roughly $57,160. At the same 35 percent rate, that deduction saves about $20,000 in tax. The difference between taking bonus and skipping it in 2024 is more than $70,000 of current year cash tax savings.

For a growing manufacturer that needs cash for payroll, inventory, or loan covenants, that timing difference matters. For a company that expects a much higher tax rate in later years, deliberately slowing deductions could make more sense. You can see why having a concrete bonus depreciation example 2024 is essential rather than blindly letting software make the choice.

KDA Case Study: Contractor Uses Bonus to Smooth a Rough Year

Consider Devon, a 1099 general contractor based in San Diego. In 2023, his net income was about $190,000, and he struggled with self employment tax and quarterly estimates. Going into 2024, he signed a large commercial buildout that required him to purchase a used skid steer, trailer, and several pieces of specialty equipment totaling $180,000 placed in service in May 2024.

When Devon engaged KDA, he had not thought past writing the checks for the equipment. We rebuilt his 2024 projection and looked at bonus and Section 179 options. By default, 60 percent bonus would give him an immediate $108,000 deduction. The remaining $72,000 would be recovered over 7 years using MACRS at roughly 14.29 percent year one, or about $10,300.

That gave him roughly $118,000 of first year depreciation instead of about $25,000 with MACRS alone. At his projected combined federal and state rate near 32 percent, we calculated current year tax savings in the $37,000 range. KDA also cleaned up his books, set up better job costing, and coordinated estimated payments so he did not run short on cash. Our fee for the year was just under $9,000, so his first year return on investment was more than 4 to 1, with ongoing savings in later years because of better recordkeeping.

Why Most Business Owners Misplay Bonus Depreciation

The most common error is assuming more acceleration is always better. That is not true once you look at your long term plan. Three traps show up again and again in returns we review.

Trap 1: Burning Deductions in a Low Income Year

If your business has a slump year or heavy loss carryforwards, stuffing more bonus deductions into that year can waste their value. A $100,000 deduction in a year where you are already at break even does not save meaningful tax. The same deduction in a year where you are solidly profitable could save $25,000 to $35,000. That is why bonus should be coordinated with your income forecast and entity structure.

Trap 2: Creating Passive Losses Real Estate Investors Cannot Use

Real estate investors love cost segregation studies because they move pieces of a building into shorter lives that can qualify for bonus. The problem is that rental real estate often produces passive losses that many investors cannot currently use due to the passive activity rules. You can generate a six figure bonus on paper and still not move your current year tax bill if your other income is W 2 salary and you do not qualify as a real estate professional. The passive rules are explained in IRS Publication 925.

Trap 3: Forgetting About Depreciation Recapture on Sale

When you sell an asset that you depreciated aggressively, part of the gain can be taxed at higher ordinary or special recapture rates rather than capital gain. If your plan is to sell equipment or a building in a few years, front loading depreciation may simply trade a lower rate now for a higher one later.

These are the types of planning puzzles where working with a firm that understands both tax law and business reality pays for itself quickly. For many growth focused owners, the sweet spot is using a mix of Section 179, bonus, and MACRS to keep taxable income in a predictable band over several years rather than swinging from zero to sky high.

How Different Taxpayers Can Use Bonus in 2024

Bonus is not just for large corporations. It matters for 1099 contractors, side hustle owners, and real estate investors as well. The key is matching the rule to your profile.

W 2 Employee With a Side Business

Jay is a software engineer with a W 2 salary of $210,000 and a photography side business that nets around $18,000 per year. In 2024, he buys a new camera body and lenses for $9,000, a computer for $2,500, and lighting gear for $3,500, all used exclusively in the business.

These items are 5 year property and qualify for bonus. If he takes 60 percent bonus on the $15,000 total, that is a $9,000 deduction, with the remaining $6,000 recovered via MACRS. At his marginal rate, that might shave $3,000 off his tax bill. Because he has significant W 2 income, passive loss limitations are not an issue here. His main concern is documenting exclusive business use, especially for the computer.

Self Employed 1099 Professional

A 1099 physical therapist who drives to clients might purchase a new vehicle over 6,000 pounds gross vehicle weight in 2024. The luxury auto limitations and business use percentage rules interact with bonus in a complicated way. In this scenario, a self employment tax calculator and careful mileage tracking can highlight whether to lean harder on bonus or let some of the deduction stretch out to keep self employment tax more stable across years.

Real Estate Investor

A buy and hold investor who acquires a small apartment building in late 2024 might commission a cost segregation study that reclassifies certain components into 5, 7, or 15 year property that qualifies for bonus. At a 60 percent rate, that can still create large first year deductions. But if the investor does not qualify as a real estate professional, the passive loss rules will control how much of that paper loss can offset salary, business income, or other categories. For more specialized guidance, KDA offers dedicated support for real estate investors navigating these tradeoffs.

What the IRS Will Look At With Aggressive Bonus Claims

Whenever a strategy moves large numbers in your favor, you should ask what the IRS cares about most. With bonus, the pressure points are usually eligibility, placed in service timing, and basis calculations.

Eligibility and Property Type

Not every asset qualifies. Bonus generally applies to new or used property with a recovery period of 20 years or less that you acquired and did not receive from a related party. Certain property, like assets used in a trade or business of furnishing lodging, have extra rules. Some improvements to non residential real property can qualify as qualified improvement property, but the details matter. The IRS discusses qualified improvement property in Tax Cuts and Jobs Act guidance.

Placed in Service Date

You only get bonus when property is placed in service during the year, not when you sign the purchase order or pay the deposit. Placed in service means it is ready and available for a specifically assigned use in your business. For complex installations, that date might be months after the invoice. Good documentation of when you started actually using the asset can protect you in an audit.

Basis and Business Use Percentage

The basis you use for bonus must be reduced for any non business use. If you buy a vehicle for $70,000 and it is only 60 percent business use, you only get to apply bonus to $42,000. Inflating business use to push more cost into bonus is a classic red flag that can trigger questions.

Red Flag Alert: If the ratio of depreciation deductions to gross revenue looks wildly out of line for your industry, expect questions. Matching your depreciation strategy to real world operations, not just the biggest number on paper, is safer and often more sustainable.

Will Bonus Depreciation Trigger an Audit?

Bonus itself is a legitimate rule baked into the tax code, not a loophole. Claiming large bonus deductions does not automatically trigger an audit. That said, unusually large deductions always increase the odds of closer review. The IRS Data Book regularly shows that small business returns with significant losses or unusual ratios see higher exam rates.

What gets taxpayers in trouble is not using bonus. It is sloppy support. Missing invoices, weak business purpose explanations, no mileage logs, or casually rounded business use percentages are what let the IRS reclassify personal costs as non deductible.

Pro Tip: Treat any asset that will generate bonus as if it were pre selected for review. That means detailed invoices, clear asset descriptions, proof of payment, documentation of placed in service dates, and logical business use explanations placed in your permanent tax file.

How Bonus Depreciation Fits Into Your Overall Strategy

Bonus is one piece of a broader framework that includes entity choice, income volatility, retirement contributions, and where you live. A California owner with high state tax costs and rapidly growing profits will use it differently than a Nevada based startup still burning cash.

For California business owners in particular, state conformity to federal depreciation rules is not always complete. Some years California has decoupled from federal bonus or limited its impact. You cannot assume your federal and state numbers will match. A comprehensive California business owner plan, like the one in KDA’s tax strategy hub, should always account for these differences.

If you are running payroll, juggling multiple entities, or layering in real estate holdings, coordinating bonus with other tools like retirement plans, health reimbursement arrangements, and income splitting can squeeze out significantly more after tax cash. KDA’s premium advisory services are built for that level of complexity.

Frequently Asked Questions About Bonus Depreciation After 2023

Can I Still Take Bonus on Used Property in 2024?

Yes, as long as the property is new to you and meets the other requirements. The expansion to used property was one of the most owner friendly changes under prior law. The phase down is about the percentage, not about restricting used assets.

What If I Do Not Want Bonus on a Particular Asset Class?

You can elect out of bonus for any class of property placed in service during the year, such as all 5 year property. That election is made on a timely filed return and generally cannot be changed later. This is one of the key levers planners use when building a multi year projection.

How Does Bonus Work With Section 199A Qualified Business Income Deduction?

Since bonus reduces taxable business income, it also shrinks the base used for the 20 percent qualified business income deduction under Section 199A in many cases. That interaction can push some owners to slow depreciation in order to preserve more QBI. The math depends heavily on your income level and whether you are in a specified service trade or business.

Can I Combine Bonus With Cost Segregation on Real Estate?

Yes. Cost segregation is simply a way of identifying and quantifying components of a building that qualify for shorter lives. Once those components are broken out as 5, 7, or 15 year property, they are eligible for bonus at the current year percentage. The question is not whether you can, but whether the resulting passive losses are usable in your situation.

Is Bonus Better Than Just Using Section 179?

Neither tool is universally better. Section 179 has dollar caps and business income limits but can be more flexible for specific assets. Bonus is percentage based and does not have the same business income cap. Many optimized plans use a combination, especially for owners who want to target particular assets or manage state conformity issues.
