Form 4562 is the IRS form used to claim deductions for depreciation and amortization, to elect Section 179 expensing, to claim the special (bonus) depreciation allowance, and to report business use of certain “listed property” (most commonly vehicles). When you buy property for use in a trade or business or for the production of income, the IRS generally requires you to spread the deduction over a number of years instead of deducting the entire cost in the year of purchase. Form 4562 records those calculations and elections and is filed with your federal income tax return for the year the property was placed in service.
Who must file
– Any taxpayer (individual, partnership, corporation, S corporation, trust, estate) that claims:
• A depreciation deduction;
• An amortization deduction;
• A Section 179 election (expense election for qualifying property); or
• Information for listed property (including business automobiles).
– Employees cannot use Form 4562 to claim job-related vehicle expenses (those miscellaneous itemized deductions were suspended by the Tax Cuts and Jobs Act for most employees).
Main parts (high-level)
– Section 179 election — elect to expense (immediately deduct) some or all of the cost of qualifying property in the year placed in service.
– Special depreciation allowance (bonus depreciation) — a first-year allowance for certain qualified property (rules changed under the Tax Cuts and Jobs Act and phase down after 2022).
– MACRS depreciation — regular depreciation under the Modified Accelerated Cost Recovery System, which assigns property to recovery periods and methods.
– Listed property and autos — business-use substantiation and allocation for items used for both business and personal purposes.
– Amortization — deduction for intangible assets (e.g., goodwill, patents) over specified recovery periods.
Practical step-by-step guide to completing and filing Form 4562
1. Confirm the year of “placed in service”
• The form applies to property placed in service during the tax year. If property was placed in service in a prior year, you generally report depreciation on that earlier year’s return.
2. Gather required information
• Purchase price (cost basis) of each asset.
• Date each asset was placed in service.
• Business or investment use percentage (if used partly for personal use).
• Prior-year depreciation (for assets placed in service earlier).
• Class life or recovery period (e.g., 5-year for most equipment, 27.5-year for residential rental property, 39-year for nonresidential real property).
• Records supporting Section 179 eligibility and listed-property use logs (mileage logs for vehicles).
3. Decide whether to elect Section 179
• Section 179 lets you expense some or all of the cost of qualifying tangible personal property and certain qualified real property in the year placed in service, subject to dollar limits and business-income limitations. Only one complete Part I is filed even if multiple properties are involved.
• Check current-year dollar limits before electing; limits change annually.
• If you elect Section 179, fill out Part I (or the Section 179 lines) and enter the elected amount. The elected amount reduces basis for bonus and regular depreciation.
4. Determine special (bonus) depreciation eligibility
• After Section 179 election, apply the special depreciation allowance to eligible property (bonus depreciation). The order is generally: Section 179 first, then bonus depreciation, then MACRS regular depreciation on the remaining basis.
• Rules and percentages for bonus depreciation have changed (e.g., 100% for property placed in service through 2022, then phased down). Check current IRS guidance.
5. Compute MACRS depreciation for remaining basis
• Assign assets to the correct MACRS class and recovery period.
• Apply the appropriate convention (half-year, mid-quarter, or mid-month for real property) and depreciation method (usually GDS 200% declining balance switching to straight line, or ADS straight line when required/ elected).
• Enter calculations in the MACRS section of the form.
6. Complete listed property and automobile reporting (if applicable)
• For any listed property (e.g., passenger automobiles, certain equipment used for both business and personal purposes), report business-use percentage, total mileage, business mileage, and depreciation allowed. For passenger autos, there are special limits and rules; keep accurate mileage logs.
7. Complete amortization (if applicable)
• For amortizable intangible assets, provide the cost, start date, amortizable amount, and period, and compute the deduction.
8. Summarize and attach
• Complete the summary section which consolidates Section 179, special depreciation, and regular depreciation totals.
• Attach Form 4562 to your income tax return (Form 1040 schedule C, Form 1065, Form 1120, etc.). If filing electronically, most tax software will include it automatically.
9. Keep supporting records
• Retain purchase invoices, depreciation schedules, Section 179 election statements, business-use logs, and other documentation. The IRS doesn’t require you to attach detailed depreciation schedules, but you must keep them in case of audit.
Common practical tips and pitfalls
– One Form 4562 per activity: File a separate Form 4562 for each trade or business activity requiring the form (not necessarily one per asset).
– Order of deductions: Section 179 first, then special (bonus) depreciation, then MACRS regular depreciation on the remaining basis.
– Prorate for business use: If property is used partly for personal use, multiply cost and depreciation by the business-use percentage. You cannot deduct depreciation for the personal portion.
– Watch listed-property substantiation: For vehicles and other listed property, maintain contemporaneous logs (dates, miles, business purpose) or risk losing deductions.
– Don’t double-count: If you elect Section 179, reduce the basis before computing bonus or normal depreciation. If bonus depreciation is claimed, it reduces the basis for subsequent MACRS.
– Deadlines: Form 4562 is filed with your tax return. If you timely file an extension for your return, you have until the extended due date to file the return and attach Form 4562.
– Changes and limits: Section 179 and bonus-depreciation limits and rules change over time. Always check the current year’s IRS instructions.
Short example (illustrative)
– You buy business equipment for $30,000 and place it in service this year. Business use is 100%.
1. Decide whether to elect Section 179 (subject to limits). If you elect to expense $10,000 under Section 179, you claim that amount in Part I.
2. If the equipment qualifies for bonus depreciation and you elect/are eligible for it, apply bonus on the remaining basis (after Section 179): $30,000 − $10,000 = $20,000. If bonus = 100% (only applicable in certain years), you could deduct the $20,000 immediately; otherwise, compute bonus percentage then MACRS on remaining basis.
3. Complete MACRS calculations (if any basis remains) in the MACRS section for subsequent years.

Part II — Additional Sections, Examples, and Practical Steps
Additional parts of Form 4562 to know
– Part IV — Listed Property: This section covers property that is susceptible to personal use (most commonly cars, other vehicles, computers, and cell phones). For listed property you must show total miles, business miles, and business-use percentage for vehicles; for other listed property you must document how much of the asset’s use is for business versus personal. If business use falls to 50% or less in a later year, you may have to recapture previously claimed depreciation or reduce future deductions.
– Part V — Special Use Vehicles: This is used to report depreciation for passenger autos and certain vehicles used for special purposes (ambulances, taxis, etc.) with special rules and limits.
– Part VI — Amortization: Reports amortization of intangible assets (for example, goodwill or organizational costs) and any amortization elections you make under Section 197 or other code sections.
– Part VII — Nondeductible and Other Info: Used to reconcile basis and other information required for tax reporting.
Practical steps for preparing and filing Form 4562
1. Gather documentation
• Purchase invoices, closing statements, or receipts showing cost and placed-in-service date.
• Records of business vs personal use (mileage logs for vehicles, usage logs for equipment).
• Previous depreciation schedules (if continuing depreciation from prior years).
2. Determine which tax treatment to use
• Section 179 election (expensing): elect to expense qualifying property, subject to limits and business income rules.
• Bonus (special) depreciation: take accelerated first-year depreciation for qualifying property (rules for percentage and qualified property may change by tax year).
• Regular MACRS depreciation: spread the deduction over the applicable recovery period.
• Decide for each asset whether to elect Section 179, claim bonus depreciation, or use regular MACRS (different assets and taxpayer situations benefit differently).
3. Calculate the business-use percentage
• For assets used partly for personal purposes, multiply cost basis by business-use percentage to find the depreciable basis.
4. Fill out the appropriate parts of Form 4562
• Part I for Section 179 election (complete this once per activity even if you have multiple assets).
• Part II for special depreciation allowance (bonus depreciation).
• Part III for MACRS depreciation (list each asset class, cost, basis, recovery period, method, and depreciation for the year).
• Parts IV–VI as needed for listed property, special vehicles, and amortization.
5. Attach Form 4562 to your tax return
• If you are a sole proprietor, attach Form 4562 to Schedule C (Form 1040).
• Corporations, partnerships, and S corporations attach it to their respective returns.
6. Retain records
• Keep worksheets, receipts, logs, and prior years’ depreciation schedules for at least the retention period required by the IRS (usually the statute of limitations for tax returns plus any longer periods for asset records).
Common examples illustrating how Form 4562 works
Example 1 — Simple Section 179 election (illustrative)
– Facts: A sole proprietor buys qualified equipment for $50,000 and places it in service during the tax year. The equipment is used 100% for business.
– Action: The owner elects Section 179 and expenses the full $50,000 on Part I of Form 4562.
– Result: The $50,000 is deducted in the current year (subject to Section 179 limits and taxable income limitations). No MACRS depreciation is claimed for that asset in later years because the basis was reduced to zero by the Section 179 election.
Example 2 — Mixed treatment with business-use percentage (illustrative)
– Facts: A partner in a firm buys a $60,000 vehicle for business. The vehicle is used 80% for business and 20% personal. The partner chooses to take Section 179 for part of the basis and regular MACRS for the remainder.
– Steps:
1. Compute depreciable basis = $60,000 × 80% business use = $48,000.
2. Elect Section 179 for, say, $30,000 of the depreciable basis on Part I (subject to limits).
3. Claim bonus depreciation (if available and chosen) or take MACRS on the remaining $18,000 basis in Part II/Part III as applicable.
– Result: Immediate deduction of $30,000 (Section 179) plus any allowed bonus amount; remaining basis depreciated under MACRS over the applicable recovery period. If business use later falls to ≤50%, recapture rules could require an ordinary income adjustment.
Example 3 — Amortization of an intangible (illustrative)
– Facts: A small business purchases a patent with a $40,000 qualified basis that must be amortized over 15 years under Section 197.
– Action: Report the amortization election and compute the annual amortization expense in Part VI of Form 4562.
– Result: $40,000 ÷ 15 = $2,666.67 amortization deduction each year (subject to first-year conventions and placed-in-service timing).
Key tax concepts to be aware of
– Business-use percentage matters: Only the portion of cost attributable to business use is depreciable or amortizable.
– Election is binding for the year: If you make a Section 179 election, it applies for that tax year and must be reported on Form 4562. Some elections are revocable only with IRS consent.
– Recapture rules: If business use drops below required thresholds (commonly 50% for listed property) or if you dispose of the asset, part of the deduction may be recaptured—treated as ordinary income under sections like 1245 or via Section 179 recapture rules.
– Listed property scrutiny: Vehicles and other listed property require substantiation (mileage logs, calendars) to support business use; failure to substantiate can severely limit deductions.
– Annual limits and phase-downs: Section 179 deduction limits and bonus depreciation percentages are set by statute and may change or phase down over time. Always check current IRS instructions for the tax year in which property is placed in service.
Common mistakes to avoid
– Failing to maintain contemporaneous mileage or use logs for listed property.
– Applying Section 179 to ineligible assets (investment property, property primarily used outside the U.S., certain lodging/hotel property, and others may be ineligible).
– Forgetting to reduce basis by prior-year Section 179 or depreciation when computing current-year deductions.
– Not filing a separate Form 4562 when required (separate forms for separate activities/businesses).
– Overlooking state tax differences: States may not conform to federal bonus depreciation or Section 179 treatment.
Where to get forms and current guidance
– Download Form 4562 and the IRS “Instructions for Form 4562” from the IRS website. The instructions explain current-year dollar limits, recovery periods, listed property rules, and examples.
– Investopedia and reputable tax publications provide useful summaries, but always cross-check and apply the current year IRS instructions for precise limits and percentages.
When to consult a tax professional
– If you have many assets, mixed personal and business use, or assets placed in service across multiple years.
– When deciding how much Section 179 to elect versus taking bonus depreciation — this can affect taxable income, state tax exposure, and future recapture.
– For complex transactions like dispositions, involuntary conversions, or transfers where depreciation recapture may apply.
– If you operate multiple businesses or activities that may require separate Forms 4562.
Concluding summary
Form 4562 is the IRS’s primary vehicle for reporting depreciation, amortization, Section 179 expensing elections, and the business use of listed property. Accurate completion begins with good records: purchase documentation, placed-in-service dates, and clear evidence of business use. Taxpayers must decide for each asset whether to take Section 179, claim bonus depreciation (when available), or depreciate under MACRS; these choices affect current-year taxable income and future tax consequences, including potential recapture. Because rules, limits, and bonus depreciation percentages change over time, consult the latest IRS Form 4562 instructions and consider professional tax advice for complex situations.
