Form 4562 Instructions (2025): Depreciation and Section 179

Updated October 9, 2026. Quick answer: Form 4562 is the IRS form for claiming depreciation and amortization, making the section 179 election, and reporting listed property such as vehicles. The 2025 instructions tell you to file it when you claim depreciation on property placed in service during 2025, among other triggers, and they print a 27.5 year recovery period for residential rental property. This page reads the 2025 form and instructions line by line for a rental owner.

What Form 4562 is and who must file it

The IRS gives the form three jobs. It says to “Use Form 4562 to:” do the following: “Claim your deduction for depreciation and amortization,” “Make the election under section 179 to expense certain property, and” “Provide information on the business/investment use of automobiles and other listed property.”

Who must file is defined by what you are claiming, not by who you are. The instructions list the triggers this way: “Except as otherwise noted, complete and file Form 4562 if you are claiming any of the following.”

TriggerWhat the instructions list
Depreciation“Depreciation for property placed in service during the 2025 tax year.”
Section 179“A section 179 expense deduction (which may include a carryover from a previous year).”
Listed property“Depreciation on any vehicle or other listed property (regardless of when it was placed in service).”
Amortization“Amortization of costs that begins during the 2025 tax year.”

Two practical points follow from the text. First, “File a separate Form 4562 for each business or activity on your return for which Form 4562 is required.” Second, the form does not make you resubmit old assets every year: “Except for Part V (relating to listed property), the IRS does not require you to submit detailed information with your return on the depreciation of assets placed in service in previous tax years.” “However, the information needed to compute your depreciation deduction (basis, method, etc.) must be part of your permanent records.”

Rental property: what depreciation means and what the instructions say about it

For a landlord the starting definition matters: “Depreciation is the annual deduction that allows you to recover the cost or other basis of your business or investment property over a certain number of years.” “Depreciation starts when you first use the property in your business or for the production of income.” The instructions also draw a line at land: “Exception. You cannot depreciate land.” If you convert a home to a rental, the placed-in-service date is the conversion date: “If you converted property held for personal use to use in a trade or business or for the production of income, treat the property as being placed in service on the conversion date.” The conversion case is walked through on converting your home to a rental.

The instructions group rental property into classes with a printed recovery period. The following table pulls the rental-relevant ones together:

ClassHow the instructions describe itRecovery period printed
Residential rental property“Residential rental property is a building in which 80% or more of the total rent is from dwelling units.”27.5 years
Nonresidential real property“Nonresidential real property is any real property that is neither residential rental property nor property with a class life of less than 27.5 years.”39 years
Appliances, carpets, furniture in a rentalListed in the instructions under 5-year property: “Appliances, carpets, furniture, etc., used in a rental real estate activity.”5 years
Residential rental property under the alternative system“The ADS recovery period for residential rental property placed in service after 2017 is 30 years.”30 years

The instructions add a convention rule: “Mid-month convention. This convention applies only to residential rental property (line 19i), nonresidential real property (line 19j), and railroad gradings and tunnel bores.” The recovery table for the 27.5 year class is labeled “Recovery period: 27.5 years”, “Convention: Mid-month” and “Method: Straight line”.

The following is an illustration with made-up amounts, not an IRS example. It shows only the straight-line idea behind the 27.5 year period, not the first-year or last-year amounts that the mid-month convention changes:

The instructions do not say which schedule a rental owner carries the result to; they name Schedule C (Form 1040) for some vehicle reporting but no rental schedule. For what happens to depreciation when a rental is sold, see depreciation recapture.

Part I: the section 179 election

Section 179 lets a taxpayer expense, rather than depreciate over time, part of the cost of qualifying property. The instructions describe the election: “You can elect to expense part or all of the cost of section 179 property (defined earlier) that you placed in service during the tax year and used predominantly (more than 50%) in your trade or business.” For the 2025 year the dollar figures are printed in the What’s New section and again on Line 1: “For tax years beginning in 2025, the maximum section 179 expense deduction is $2,500,000.” “This limit is reduced by the amount by which the cost of section 179 property placed in service during the tax year exceeds $4,000,000.”

Landlords should read two limits closely. The definition of section 179 property carves out “Property held for investment (section 212 property).” And for rented-out equipment: “However, for taxpayers other than a corporation, this election does not apply to any section 179 property you purchased and leased to others unless:” the instructions then give two exceptions, one of which is “You manufactured or produced the property; or” Whether a particular rental asset passes those tests is a facts question for the return.

The form walks the limit through five lines:

Form lineWording on the form
Line 1Maximum amount (see instructions)
Line 2Total cost of section 179 property placed in service (see instructions)
Line 3Threshold cost of section 179 property before reduction in limitation (see instructions)
Line 4“Reduction in limitation. Subtract line 3 from line 2. If zero or less, enter -0-”
Line 5“Dollar limitation for tax year. Subtract line 4 from line 1. If zero or less, enter -0-.”

The following is an illustration with made-up amounts, not an IRS example, using the two limits quoted above:

StepAmountNote
Cost of all section 179 property placed in service (line 2, input to the computed rows below)$4,300,000Illustration input

Dollar limitation (line 5): $2,500,000 minus $300,000$2,200,000Computed here

Two more rules shape the election. On timing: “You must make the election on Form 4562 filed with either:” the original return for the year the property was placed in service, or an amended return filed within the time the instructions describe. On the interaction with other deductions: “If you elect to expense section 179 property, you must reduce the amount on which you figure your depreciation or amortization deduction (including any special depreciation allowance) by the section 179 expense deduction.”

Part II: the special depreciation allowance

Part II is where the so-called bonus depreciation goes. The instructions explain its place in the order of operations: “The allowance is an additional deduction you can take after any section 179 expense deduction and before you figure regular depreciation under MACRS.” “The special depreciation allowance applies only for the first year the property is placed in service.”

For 2025 the rate depends on when the property was acquired. The instructions say “Certain qualified property (defined below) acquired after January 19, 2025, is eligible for a 100% special depreciation allowance.” “However, you can elect to take a 40% special depreciation allowance for certain qualified property” in place of the 100% allowance in the first tax year ending after January 19, 2025.

Whether a rental asset qualifies turns on the definition: “Tangible property depreciated under MACRS with a recovery period of 20 years or less;” is the first item in the qualified property list. Comparing that text with the table above, appliances and furniture in a rental sit in a 5 year class that is within 20 years, while the 27.5 year class for the building itself is longer than 20 years. The instructions do not say in this passage which of a landlord’s assets qualify beyond that definition, and point to “See Pub. 946 for more information.”

Part III MACRS, Part V listed property, and Part VI amortization

Part III is the regular depreciation schedule. The instructions define the system: “The Modified Accelerated Cost Recovery System (MACRS) is the current method of accelerated asset depreciation required by the tax code.” “Generally, MACRS is used to depreciate any tangible property placed in service after 1986.” The basis you enter is not simply the price: “To find the basis for depreciation, multiply the cost or other basis of the property by the percentage of business/investment use.” “From that result, subtract any credits and deductions allocable to the property.”

Part V covers listed property. The instructions define it as including “Passenger automobiles weighing 6,000 pounds or less.” and warn that a vehicle claim brings the form in: “If you claim the standard mileage rate, actual vehicle expenses (including depreciation), or depreciation on other listed property, you must provide the information requested in Part V, regardless of the tax year the property was placed in service.”

Part VI is for amortization. The instructions open it with “Each year, you can deduct part of certain capital costs over a fixed period.” and block double counting: “If you amortize property, the part you amortize does not qualify for the section 179 expense deduction or for depreciation.” For the tax-side effects of depreciation on a later sale, see Form 4797 and Form 8582 for passive activity limits.

Common mistakes

  • Depreciating the land along with the building. The instructions say plainly: “Exception. You cannot depreciate land.”
  • Treating the section 179 limit as automatic for rented-out property. The instructions exclude “Property held for investment (section 212 property).” from the definition and restrict the election for property leased to others.
  • Ignoring the starting date after a conversion. The instructions say that for a home turned rental you “treat the property as being placed in service on the conversion date.”
