IRS Form 4562 – Depreciation and Amortization

Form 4562 reports the tax recovery of costs that usually cannot be deducted all at once. It brings together the Section 179 election, special depreciation allowance, Modified Accelerated Cost Recovery System depreciation, deductions for assets placed in service before the current year, listed-property substantiation, and amortization. The final 2025 form is current, and the IRS released final 2025 instructions reflecting legislation enacted before their March 2026 revision date.

The form is not merely a summary of accounting depreciation. Federal tax law determines an asset’s basis, placed-in-service date, recovery period, method, convention, and eligibility for accelerated deductions. A business preparing Schedule C, a rental owner using Schedule E, a farmer using Schedule F, or an entity return may all need Form 4562, often one form for each separate business or activity.

Decide which property belongs on the 2025 form

Property first used and available for its intended business purpose during 2025 is generally placed in service in 2025, even if it was purchased earlier. A delivery van sitting at the dealer is not placed in service; a van delivered, insured, and ready for deliveries generally is. That date controls the year’s depreciation and can determine whether the mid-quarter convention applies. Land is not depreciable, so the purchase price of real estate must be allocated between land and depreciable buildings or improvements.

Form 4562 is generally required for depreciation of property placed in service during the year, Section 179 expense, depreciation on listed property, certain vehicle deductions, and amortization beginning in the year. It may also be required when claiming a deduction for property carried from earlier returns. The instructions provide limited exceptions, such as reporting only pre-1987 depreciation without listed property, but a continuing depreciation schedule should still reconcile to the return.

Part I makes the Section 179 election

Section 179 lets an eligible taxpayer elect to expense qualifying property instead of recovering the full cost over future years. For tax years beginning in 2025, the current instructions state a maximum deduction of $2,500,000 and a phaseout threshold of $4,000,000, subject to the taxable-income limitation. The limit is shared across qualifying assets and, for married taxpayers, across spouses. Certain sport utility vehicles have a separate cap.

Qualifying property generally includes tangible personal property acquired for active business use and certain qualified real property elected under the statute. Property acquired from related persons, property used predominantly outside the United States, and property used by certain tax-exempt organizations or governmental units may be excluded. The election identifies cost and elected expense by asset. A pass-through entity makes its election at entity level, and owners separately apply their own limits.

The business-income limit can defer part of a valid Section 179 election. The disallowed amount is carried to a later year rather than converted into ordinary depreciation in the current computation. This is why an asset ledger should retain original cost, elected amount, allowed amount, and carryover. If business use later falls to 50% or less, recapture can be required and is reported in Part IV.

Special allowance and MACRS are separate layers

Part II covers the special depreciation allowance and certain other depreciation. Eligibility depends on the property type, acquisition and placed-in-service dates, prior use, and elections made. A taxpayer may elect out for a class of property, but the election must be made consistently for that class and year. Do not treat a software default as evidence that the election was intended.

Part III computes MACRS deductions. Most new tangible property is classified under the General Depreciation System, with recovery periods based on the asset class. The Alternative Depreciation System is mandatory for some property and elective for others. The half-year convention is common, but the mid-quarter convention generally applies when more than 40% of the aggregate basis of qualifying personal property is placed in service during the last three months of the year. Real property uses a mid-month convention.

Listed property demands usage records

Part V applies to listed property, including passenger automobiles and other property specified by law. Vehicles have annual depreciation limitations, and deductions depend on qualified business-use percentage. Commuting is personal use even when the trip is necessary to reach work. A contemporaneous mileage log should distinguish business destinations and purposes from commuting and other personal miles. Actual-expense and standard-mileage methods also have their own eligibility rules.

If qualified business use is not more than 50%, Section 179 and accelerated methods are restricted, and straight-line recovery under the alternative system may apply. If use falls after accelerated deductions were claimed, the recapture calculation in Part IV compares deductions taken with deductions that would have been allowed under the required method. The recaptured amount generally becomes ordinary income on the activity’s return.

Amortization covers a different family of costs

Part VI is for costs recovered over a stated period rather than depreciated as tangible property. Common examples include Section 197 intangibles acquired as part of a trade or business, business startup costs that were not currently deducted, organizational costs, and certain research or experimental expenditures under the rules applicable to the tax year. Each item needs a description, starting date, amortizable amount, code section, period or percentage, and current deduction.

An acquired Section 197 intangible usually has a 15-year period beginning with the month acquired, while other costs follow their governing provision. Grouping costs without preserving the legal category can create errors when an asset is sold or abandoned. Keep the underlying agreement and allocation, because a later disposition may require basis information on Form 4797.

Reconcile the form to books and disposal reporting

Prepare Form 4562 from a tax fixed-asset register, not from the current financial-statement expense alone. Reconcile beginning tax basis, additions, disposals, transfers, current deductions, and ending basis. Separate repairs that are currently deductible from improvements that must be capitalized, applying the tangible property regulations and elections relevant to the return. For real property, retain the land allocation and improvement histories by unit.

When an asset is sold, exchanged, converted to personal use, abandoned, or destroyed, remove it from the depreciation schedule as of the correct date. The accumulated depreciation affects gain, loss, and ordinary-income recapture on Form 4797 or another disposition form. A casualty may also involve Form 4684. The return should not keep depreciating property after its recovery period or disposition.

Before filing, review whether only one complete Part I summarizes the taxpayer’s Section 179 election, while separate Forms 4562 support each activity. Check the convention, business-use percentage, passenger-auto limits, and any election statements. Those steps turn the form from a one-year deduction claim into a reliable basis record for every later year.
