Complete Guide to Section 179 Deduction (2024 Update)
The Section 179 deduction is one of the most valuable tax breaks available to small and medium-sized businesses in the United States. This IRS tax code provision allows businesses to deduct the full purchase price of qualifying equipment and software purchased or financed during the tax year, rather than depreciating it over several years.
What is Section 179?
Section 179 of the IRS tax code was designed to encourage businesses to invest in themselves by purchasing equipment and software. Normally, when your business buys certain items of property, you must write them off a little at a time through depreciation. Section 179 allows you to deduct the full purchase price from your gross income in the year you place the equipment in service.
Key Benefits of Section 179
- Immediate Expensing: Deduct the full cost of qualifying equipment in the year it’s purchased
- Cash Flow Improvement: Reduces your taxable income, lowering your tax bill
- No Depreciation Scheduling: Avoid complex depreciation calculations
- Works with Financing: Applies to both purchased and financed equipment
- Bonus Depreciation: Can be combined with bonus depreciation for even greater savings
Section 179 Deduction Limits for 2024
The Section 179 deduction limits are adjusted annually for inflation. For tax year 2024:
- Maximum Deduction: $1,220,000
- Phase-Out Threshold: $3,050,000 (deduction begins to phase out dollar-for-dollar after this amount)
- Bonus Depreciation: 80% (phasing down from 100% in previous years)
| Year | Section 179 Limit | Phase-Out Threshold | Bonus Depreciation |
|---|---|---|---|
| 2024 | $1,220,000 | $3,050,000 | 80% |
| 2023 | $1,160,000 | $2,890,000 | 100% |
| 2022 | $1,080,000 | $2,700,000 | 100% |
| 2021 | $1,050,000 | $2,620,000 | 100% |
Qualifying Property for Section 179
To qualify for the Section 179 deduction, property must meet these requirements:
- Tangible Personal Property: Machinery, equipment, computers, office furniture, etc.
- Off-the-Shelf Computer Software: Must be purchased (not custom-developed)
- Qualified Improvement Property: Interior improvements to non-residential buildings
- Business Use Requirement: Must be used more than 50% for business purposes
- Placed in Service: Must be put into use during the tax year you’re claiming the deduction
How Section 179 Works with Bonus Depreciation
Bonus depreciation is another tax incentive that can be used in conjunction with Section 179. While Section 179 has annual limits, bonus depreciation allows you to deduct a percentage of the remaining cost after applying Section 179. For 2024, bonus depreciation is 80%, phasing down from 100% in previous years.
Example Calculation:
If you purchase $200,000 of qualifying equipment in 2024:
- Apply Section 179 deduction: $1,220,000 limit (full $200,000 qualifies)
- Remaining amount after Section 179: $0 (since full amount was deducted)
- Bonus depreciation would apply to any amount over the Section 179 limit
Section 179 vs. Regular Depreciation
| Feature | Section 179 | Regular Depreciation |
|---|---|---|
| Deduction Timing | Full deduction in year of purchase | Spread over useful life (3-39 years) |
| Deduction Amount | Up to $1,220,000 (2024) | Varies by asset class |
| Income Limitation | Cannot create a loss (limited to taxable income) | No income limitation |
| Phase-Out | Begins at $3,050,000 of purchases | No phase-out |
| Bonus Depreciation | Can be combined | Can be used separately |
How to Claim Section 179 on Your Tax Return
To claim the Section 179 deduction:
