IRS Form 4562: Complete Guide for 2026
Form 4562 — Depreciation and Amortization
Form 4562 is used to claim depreciation on business assets, Section 179 expensing, and bonus depreciation. When you purchase equipment, vehicles, computers, or other assets for your business, you generally can't deduct the full cost in the year of purchase — instead, you depreciate it over its useful life. This form also covers amortization of intangible assets like patents and goodwill.
Who Needs to File
Any business owner who placed depreciable property in service during the tax year, claims Section 179 expensing, or claims bonus depreciation. Also required if you claim depreciation on listed property (vehicles, computers used partly for personal purposes). If you bought equipment costing more than $2,500, you likely need this form.
Filing Deadline
Filed with your Form 1040 and Schedule C. Due April 15, 2027 for tax year 2026.
Key Lines Explained
| Line | Name | What It Means |
|---|---|---|
| Part I, Line 1 | Maximum Section 179 deduction | The maximum amount you can expense under Section 179 for 2026 (indexed for inflation, approximately $1,220,000). This lets you deduct the full cost of qualifying assets in the year of purchase instead of depreciating over time. |
| Part II, Line 14 | Special depreciation allowance (bonus depreciation) | Bonus depreciation allows you to deduct a large percentage of an asset's cost in the first year. For 2026, the rate is 20% (phasing down from 100% in 2022). Applies to new and used property. |
| Part V | Listed property | Assets used for both business and personal purposes, such as vehicles, cameras, and computers. You must track and report the business-use percentage. If business use is 50% or less, you cannot use Section 179 or bonus depreciation. |
| Line 22 | Total depreciation | The total depreciation claimed for all assets. This amount flows to Schedule C as a deduction against business income. |

Common Mistakes to Avoid
- 1
Not electing Section 179 when it would be more beneficial than regular depreciation, especially for small purchases
- 2
Forgetting to track business-use percentage for listed property like vehicles — the IRS requires contemporaneous records
- 3
Exceeding the Section 179 income limitation (you cannot create a business loss with Section 179)
- 4
Not knowing that bonus depreciation rates are phasing down: 40% in 2025, 20% in 2026, 0% in 2027
- 5
Failing to account for the luxury auto depreciation limits when depreciating a passenger vehicle

Frequently Asked Questions
What is Section 179 and should I use it?
Section 179 lets you deduct the full purchase price of qualifying business equipment in the year you buy it, instead of depreciating it over several years. It's beneficial for small businesses that want immediate tax relief. However, you can't use Section 179 to create a business loss — the deduction is limited to your taxable business income.
What is the difference between Section 179 and bonus depreciation?
Section 179 is an election to expense qualifying assets up to an annual limit and cannot create a business loss. Bonus depreciation applies automatically to eligible property and can create a loss. For 2026, bonus depreciation is 20%. Many businesses use Section 179 first, then bonus depreciation on the remaining cost.
How do I depreciate a vehicle used for business?
Vehicles are "listed property" with special rules. You must document business-use percentage with a mileage log. If business use exceeds 50%, you can use Section 179 or bonus depreciation, subject to annual luxury auto limits (around $12,400 first year for 2026). If 50% or less, you must use straight-line depreciation over 5 years.
