Let’s talk about the form that turns your big purchases into small, digestible tax deductions over time. When you buy a major asset for your business, a delivery van, a machine, a new computer server, or even intangible property like a patent or franchise, you generally can’t write off the entire cost in the year you buy it. That’s where depreciation (for tangible stuff) and amortization (for intangible stuff) come in. Form 4562 is how you calculate and claim that multi-year tax deduction.
This form is your annual playbook for recovering the cost of your capital investments. If you don’t file it, you don’t get the deduction.
The Core Concept
The IRS assigns a “class life” to almost everything you might buy for business. They’ve decided how many years you can reasonably expect to use it. You get to deduct a portion of the cost each year over that period.
Common Examples:
- 5-Year Property: Computers, office equipment, cars, light-duty trucks, research equipment.
- 7-Year Property: Office furniture, fixtures, agricultural machinery.
- 27.5-Year Property: Residential rental property (buildings, not land).
- 39-Year Property: Non-residential commercial buildings.
- Section 197 Intangibles (15-Year): Goodwill, patents, trademarks, franchise rights, customer lists you buy when acquiring a business.
The Big Decision
This is where the strategy comes in. You don’t always have to stretch the deduction out. There are ways to accelerate it, and Form 4562 is where you make that election.
1. Regular MACRS Depreciation (Part III):
This is the default, slow-and-steady method. You use the IRS’s prescribed tables to calculate your annual deduction. A $50,000 machine (5-year property) might give you a $10,000 deduction in Year 1, $16,000 in Year 2, and so on, due to accelerated tables.
2. Section 179 Expensing (Part I):
This is the “accelerate everything” option for smaller businesses. For 2024, you can immediately deduct up to $1.22 million of qualifying property placed in service during the year. There’s a catch: the deduction begins to phase out dollar-for-dollar once you put more than $3.05 million of property into service for the year. Also, you cannot use Section 179 to create a net loss on your business: it’s limited to your taxable income.
Example: You buy $80,000 worth of new computers and furniture. Instead of depreciating it over 5-7 years, you can elect Section 179 and write off the entire $80,000 this year.
3. Special (Bonus) Depreciation (Part II):
This is a separate, powerful acceleration tool. For qualified property (generally new property with a recovery period of 20 years or less) acquired after September 27, 2017, you can take an additional 100% first-year deduction. Yes, 100%. This is phasing down, but for many assets, it’s still the rule. The key difference from Section 179: Bonus depreciation can create or increase a net loss.
Example: You buy a $100,000 company car (subject to luxury auto limits, but follow the concept). With 100% bonus depreciation, you deduct $100,000 in Year 1.
The Strategy: Often, you use Section 179 for assets that don’t qualify for bonus (like used property) and to manage your taxable income. You use Bonus Depreciation for everything else that qualifies. Whatever is left over after these accelerations gets depreciated normally in Part III.
The “Listed Property” and “Luxury Auto” Rules (Part V)
This is the IRS’s “gotcha” section for assets that could have personal use.
- Passenger Vehicles: This is the famous “luxury auto” limit. Even if your Tesla Model 3 costs $60,000, the IRS limits your first-year depreciation deduction (for 2024) to $20,400 if you use bonus, or $12,400 if you don’t. These limits apply each year, drastically slowing your cost recovery. You must track business vs. personal use (Part V).
- Other Listed Property: Computers, cell phones, cameras, and property used for entertainment. If the asset is used more than 50% for business, you can depreciate it. If not, you must use the slower, straight-line method and track it here.
You’ll use different parts of the form for different assets:
- Part I: For assets you want to Section 179.
- Part II: For assets eligible for Bonus Depreciation.
- Part III: For assets being depreciated under Regular MACRS (including any assets from Parts I & II where you didn’t take 100% in the first year).
- Part IV: For Amortization of intangible assets (like that 15-year franchise fee).
- Part V: For Listed Property (vehicles, computers) to prove business use.
- Part VI: For assets you’re depreciating under a method other than MACRS (like the Alternative Depreciation System (ADS) for certain property or if you elect out of bonus).
Frequently Asked Questions (FAQ)
I bought a new laptop for $1,500. Do I need to fill out this whole form?
Possibly not. The IRS has a “de minimis” safe harbor election. You can make an accounting policy to immediately deduct (expense) items costing less than $2,500 per item or invoice. You do this on your books, not on Form 4562. If you expense it, you don’t depreciate it. If you don’t have such a policy, then yes, a laptop goes on Form 4562 as 5-year property.
What’s the difference between depreciation and a repair?
A repair keeps the asset in working order. You fix the AC in your company truck—that’s an immediate deductible expense. Depreciation is for the cost of the asset itself. Buying the truck is a capital expense you depreciate. Replacing the entire engine might be considered a capital improvement (depreciable) and not a repair. This distinction is a major audit issue.
Can I depreciate the cost of land I bought for my business?
No. Never. Land is considered to last forever, so its cost is not recoverable through depreciation. You only depreciate the building or improvements on the land. You must separate the purchase price between land and building when you buy.
I started my business in July and bought equipment. Do I get a full year of depreciation?
No, you get a “half-year” or “mid-quarter” convention. The IRS assumes all assets were placed in service in the middle of the year (or middle of the quarter if you bought a lot late in the year). Your first-year deduction is always partial. The Form 4562 instructions have the tables that apply this rule.
What if I sell an asset before I’ve finished depreciating it?
You have a “disposition.” Let’s say you bought a machine for $10,000, depreciated $6,000 of it, and then sold it for $3,000. Your adjusted basis is $4,000 ($10k – $6k). You sold it for $3k, so you have a $1,000 loss. That loss is reported on Form 4797 (Sales of Business Property), not Form 4562. Form 4562 is for claiming the deduction; Form 4797 is for cleaning up when you sell.
I use my personal car for business 60% of the time. How do I handle that?
You have two choices, and Form 4562 (Part V) is involved in one of them.
1. Actual Expense Method: You track all car-related costs (gas, insurance, repairs, lease payments). You depreciate the car’s cost (subject to luxury auto limits) and multiply all expenses, including depreciation, by 60% (your business use). You need Form 4562 for the depreciation part.
2. Standard Mileage Rate: For 2024, you deduct 67 cents per business mile. This rate is designed to cover all costs, including depreciation. You cannot also depreciate the car. You do not use Form 4562 for the car in this case. You just track miles.
How long do I need to keep records for this?
Until you sell the asset, plus 3-7 years after you file the return for the final year of depreciation. Since you might be depreciating a building for 39 years, you need to keep the original purchase documents for decades. Your depreciation schedule is a permanent part of your tax file.
Form 4562 is the map of your business’s capital investments. Doing it right requires knowing what you bought, when you bought it, how much it cost, and choosing the best tax strategy (Section 179 vs. Bonus vs. regular). A major mistake, like incorrectly classifying a repair as a capital asset or messing up the business-use percentage for a vehicle, can lead to lost deductions or penalties. For anything beyond a few simple office furniture purchases, it’s worth having your tax pro handle this. They’ll ensure you’re accelerating deductions where possible and maintaining the proper schedules that will be critical if you ever sell the asset or get audited.
