Depreciation and Asset Tracking

Determine the correct tax treatment for business assets: immediate expensing vs. capitalization and depreciation. Track each asset’s basis, method, and accumulated depreciation.

The core question: expense or capitalize?

When you buy something for your business, the tax treatment depends on two factors:

1. Cost — Is it above or below $2,500?
2. Useful life — Will it last more than one year?

If the answer to both is “above $2,500” and “more than one year,” you generally must capitalize the asset and depreciate it over time. But there are several ways to accelerate or fully expense the cost in year one.

Decision tree

Purchase amount ≤$2,500?
  └─ YES → Expense immediately (de minimis safe harbor)
  └─ NO → Useful life > 1 year?
       └─ NO → Expense immediately (ordinary business expense)
       └─ YES → Choose: Section 179, bonus depreciation, or regular MACRS

Option 1: De minimis safe harbor (≤$2,500)

Items costing $2,500 or less per invoice (or per item if the invoice lists items separately) can be expensed immediately rather than depreciated.

Requirements:

• Must make an annual election by attaching a statement to your tax return
• The $2,500 threshold applies per invoice or per item — not per total purchase. If you buy 10 monitors at $400 each on one invoice for $4,000, each monitor is under $2,500 and qualifies
• Must have written accounting procedures in place (or follow IRS guidelines)

For businesses with audited financial statements (AFS): The threshold is $5,000 per item instead of $2,500. Most small businesses don’t have AFS, so $2,500 applies.

Common items that qualify: Laptops under $2,500, monitors, keyboards/mice, basic printers, office chairs, desks, external hard drives, tablets, basic smartphones, small tools, basic software licenses.

Common items that DON’T qualify (over $2,500): MacBook Pro ($2,499+ configurations), high-end monitors ($2,500+), standing desk setups ($2,500+ total), photography equipment, specialized machinery, vehicles.

Option 2: Section 179 (full first-year expensing)

Allows you to deduct the full cost of qualifying assets in the year they’re placed in service, regardless of useful life.

2024 limits (adjust annually for inflation):

• Maximum deduction: $1,220,000
• Phase-out begins at: $3,050,000 total asset purchases for the year
• Phase-out is dollar-for-dollar: if you buy $3,200,000 in assets, your Section 179 limit drops to $1,070,000

What qualifies:

• Tangible personal property: computers, machinery, equipment, furniture, vehicles (with limitations)
• Off-the-shelf software (not custom-developed)
• Certain improvements to nonresidential real property: roofs, HVAC, fire protection, alarm/security systems
• Qualified improvement property (interior improvements to nonresidential buildings)

What does NOT qualify:

• Real property (buildings, structural components)
• Land
• Inventory
• Property used outside the US
• Property acquired from a related party
• Air conditioning or heating units (unless part of a building improvement)

Vehicle limitations (Section 179):

• SUVs over 6,000 lbs GVWR: Section 179 limited to $28,900 (2024). The rest must use bonus depreciation or regular MACRS.
• Passenger automobiles: subject to annual luxury auto limits (see vehicle-expenses skill)
• Heavy vehicles over 6,000 lbs GVWR that are NOT SUVs (trucks, vans): no special Section 179 limit — full deduction allowed

Key advantage: You choose exactly how much to expense under Section 179 (up to the limit). This gives you control over your taxable income.

Key limitation: Section 179 cannot create or increase a net loss. The deduction is limited to your taxable income from all active trades or businesses. Any unused amount carries forward to future years.

Option 3: Bonus depreciation (first-year percentage)

Allows a percentage of the asset’s cost to be deducted in the first year, with the remainder depreciated normally.

Phase-out schedule:

Year placed in service	Bonus depreciation %
2022 and earlier	100%
2023	80%
2024	60%
2025	40%
2026	20%
2027+	0%

What qualifies: Most tangible property with a MACRS recovery period of 20 years or less, computer software, qualified film/TV/live theatrical production, specified plants. Both new and used property qualify (since TCJA 2017 — previously only new property).

Key advantages over Section 179:

• No annual dollar limit
• Can create or increase a net loss (unlike Section 179)
• Applies automatically unless you elect out

Key disadvantage: You don’t control the amount — it’s all or nothing for each asset. To partially use bonus depreciation, you’d use Section 179 for the controlled portion.

Electing out: You can elect out of bonus depreciation on a class-by-class basis (e.g., elect out for all 5-year property but keep it for 7-year property). Do this if you want to spread the deduction over multiple years — useful if you expect higher income in future years.

Option 4: Regular MACRS depreciation

If you don’t use Section 179 or bonus depreciation (or for the portion not covered by them), assets are depreciated under MACRS (Modified Accelerated Cost Recovery System).

Common MACRS class lives

Asset type	Recovery period	Examples
3-year	3 years	Tractor units, racehorses, some manufacturing tools
5-year	5 years	Computers, peripherals, copiers, typewriters, automobiles, light trucks, research equipment, certain manufacturing equipment
7-year	7 years	Office furniture (desks, chairs, filing cabinets), fixtures, agricultural machinery, any asset without a designated class life
10-year	10 years	Water transportation equipment, some fruit/nut trees
15-year	15 years	Land improvements (fences, roads, sidewalks, landscaping, parking lots), qualified improvement property
27.5-year	27.5 years	Residential rental property
39-year	39 years	Nonresidential real property (office buildings, retail stores, warehouses)

Depreciation methods

GDS (General Depreciation System) — Default. Uses 200% declining balance for 3-, 5-, 7-, 10-year property; 150% declining balance for 15-, 20-year property; straight-line for 27.5- and 39-year property.

ADS (Alternative Depreciation System) — Required for certain situations (listed property used ≤50% for business, tax-exempt use property, farming with elected straight-line). Uses straight-line depreciation with longer recovery periods.

Half-year and mid-quarter conventions

Half-year convention (default): Regardless of when during the year you bought the asset, you get half a year’s depreciation in year 1 and half a year in the final year. This is the standard.

Mid-quarter convention (triggered): If more than 40% of your total asset purchases for the year are placed in service in Q4, ALL assets for the year use the mid-quarter convention instead. This generally results in less depreciation for Q4 purchases (1.5 months instead of 6 months). Watch for this if you’re buying a lot of equipment late in the year.

Asset tracking register

Maintain a register of all capitalized assets:

Asset	Date placed in service	Cost basis	Business use %	Method	Prior depreciation	Current year	Remaining basis
MacBook Pro 16”	2024-03-15	$3,499	100%	Sec 179	$3,499	$0	$0
Herman Miller desk	2024-06-01	$2,800	100%	Bonus 60%	$1,680	$160	$960
Honda CR-V (business)	2023-09-01	$32,000	75%	MACRS 5yr	$7,200	$3,840	$12,960
Office renovation	2024-01-15	$18,000	100%	MACRS 15yr	$600	$1,200	$16,200

Update this register annually when preparing tax returns. Your accountant needs this to complete Form 4562.

Disposition of assets

When you sell, trade in, donate, or discard a depreciated asset:

Gain calculation: Sale price − remaining basis = gain. If the sale price exceeds original cost, you have a gain. If it’s between remaining basis and original cost, you have depreciation recapture (taxed as ordinary income, up to 25% for real property). If it’s below remaining basis, you have a loss.

Section 179 recapture: If business use of a Section 179 asset drops to 50% or below before the end of the MACRS recovery period, you must recapture (add back to income) the excess Section 179 benefit.

Fully depreciated assets still in use: No more depreciation expense, but keep them on the register until disposed of. If you sell a fully depreciated asset, the entire sale price is gain.

Common mistakes

Expensing assets over $2,500 without Section 179 election. A $3,000 laptop put in “Office Supplies” is wrong unless you’ve made a Section 179 election on Form 4562.

Forgetting the de minimis election. The $2,500 safe harbor requires an annual election statement. Without it, even a $500 chair technically should be depreciated (though in practice the IRS rarely enforces this for very small amounts).

Depreciating land. Land is never depreciable. When you buy property, allocate between building (depreciable) and land (not depreciable) based on appraisal or tax assessment ratios.

Using the wrong class life. A computer is 5-year property, not 7-year. Office furniture is 7-year, not 5-year. Using the wrong class life changes the annual deduction amount and can trigger issues on audit.

Not tracking business-use percentage. If business use of an asset drops below 50% in any year, you must switch from MACRS to ADS (slower depreciation) and may need to recapture previously claimed Section 179 or bonus depreciation. Track business-use percentages annually.
