IRS Publication 534 – Depreciating Property Placed In Service Before 1987

IRS Publication 534 – If your business or rental property includes assets placed in service before 1987—such as older buildings, vehicles, machinery, or equipment—you may still need to calculate depreciation, handle dispositions, or address recapture rules on your tax return. IRS Publication 534 is the official IRS resource dedicated exclusively to these legacy depreciation rules.

This free 21-page guide (revised November 2016, Cat. No. 15064O) remains the authoritative source as of 2026 for property placed in service before 1987. Property placed in service after 1986 follows the Modified Accelerated Cost Recovery System (MACRS) detailed in the current Publication 946.

In this comprehensive guide, we break down everything in Pub 534: what it covers, key rules, ACRS tables, examples, and how to apply it today. Whether you’re a small business owner, real estate investor, or tax professional, this SEO-optimized resource helps you stay compliant and maximize legitimate deductions.

What Is IRS Publication 534 and Who Needs It?

IRS Publication 534, titled Depreciating Property Placed in Service Before 1987, explains how to recover the cost of business or income-producing property through annual depreciation deductions under pre-1987 tax law.

Depreciation accounts for wear and tear, age, deterioration, or obsolescence. The publication distinguishes depreciation (for tangible and certain intangible assets) from amortization (covered in Pub. 535, Chapter 8).

Key audience in 2026:

  • Taxpayers still depreciating long-life pre-1987 real estate (e.g., 19-year property placed in service in 1986 may have had extended recovery under alternate methods).
  • Anyone disposing of or selling legacy assets (triggers recapture rules).
  • Businesses reviewing historical records for audits or amended returns.
  • Tax preparers handling older rental properties or equipment.

Note: Most personal property (3-, 5-, or 10-year classes) is fully depreciated decades ago. Real property and elected longer alternate periods may still require attention.

The publication cross-references Form 4562 (Depreciation and Amortization) for reporting and warns about alternative minimum tax (AMT) implications for accelerated methods (see Form 6251).

Chapter 1: Accelerated Cost Recovery System (ACRS) – The Core of Pre-1987 Depreciation

ACRS is the mandatory system for most tangible depreciable property placed in service after 1980 and before 1987. It uses fixed percentage tables applied to the unadjusted basis (cost or other basis minus Section 179 deductions and amortization, without subtracting prior depreciation).

Qualifying Property and Recovery Classes

ACRS applies to new or used tangible property used in a trade/business or for income production. It excludes:

  • Intangible property
  • Property using non-year-based methods
  • Certain public utility property (unless normalized)
  • Post-1986 additions/improvements (use MACRS)

Main recovery classes (determined by property type and placement date):

  • 3-year property: Automobiles, light trucks, racehorses over 2 years old, certain farm equipment.
  • 5-year property: Computers, copiers, office machinery, cars/light trucks (some), petroleum storage, single-purpose agricultural structures.
  • 10-year property: Manufactured homes, railroad tank cars, vessels, theme park structures.
  • 15-year real property: Pre-March 16, 1984 real estate; low-income housing (special tables).
  • 18-year real property: Placed in service March 16, 1984 – May 8, 1985.
  • 19-year real property: Placed in service after May 8, 1985 and before 1987 (most nonresidential real property).

How to Figure the ACRS Deduction?

  1. Determine unadjusted basis.
  2. Identify the recovery class and year.
  3. Multiply by the percentage from the appropriate ACRS table in the Appendix.

Half-year convention is built into most tables (property treated as placed in service mid-year). Real property uses full-month or mid-month conventions.

Example from Pub 534: You bought a $37,500 mobile home (10-year property) on April 21, 1986.

  • 1986: 8% × $37,500 = $3,000
  • 1987: 14% × $37,500 = $5,250
    (and so on until fully recovered).

Alternate ACRS Method (Modified Straight Line): You could elect longer recovery periods (e.g., 5, 12, or 25 years for 3/5-year property; 35 or 45 years for real property) with straight-line percentages and half-year convention. The election is irrevocable without IRS consent.

Early Dispositions and Recapture

  • 3-, 5-, 10-year property: No depreciation deduction in the year of disposition.
  • 15-, 18-, 19-year real property: Prorate based on months of use (full-month pre-June 23, 1984; mid-month after).
  • Recapture: Section 1245 (personal property) or 1250 (real property) treats gain as ordinary income to the extent of prior depreciation. See Pub. 544 for details.

Chapter 2: Other Methods of Depreciation (Pre-1981 or Excluded Property)

For property placed in service before 1981 or not qualifying for ACRS/MACRS (e.g., certain intangibles, public utilities, videocassettes), use these methods:

  • Straight Line: (Adjusted basis – salvage value) ÷ useful life. Prorate short years.
  • Declining Balance: Up to 200% of straight-line rate applied to adjusted basis each year (salvage ignored initially but cannot go below it).
  • Income Forecast: For videocassettes/films—depreciation based on current-year income ÷ total estimated lifetime income.

Example (Declining Balance): $10,000 asset, 5-year life (20% rate) → Year 1: $2,000; Year 2: $1,600 (20% of $8,000 remaining).

Changing Methods: Switch from declining balance to straight line without consent on the original return. Other changes may require Form 3115.

Dispositions: Normal vs. abnormal retirements; gain/loss rules per Pub. 544.

Chapter 3: Special Rules for Listed Property

Listed property includes passenger automobiles, computers/peripheral equipment (pre-1987 rules), boats, airplanes, and property used for entertainment/recreation.

Predominant Use Test: Must be used >50% for qualified business use each year (including the first recovery year).

  • If failed in placement year: No Section 179, must use straight-line.
  • After recovery period: Continue straight-line if business use drops ≤50%.
  • Recordkeeping: Strict contemporaneous records required (date, mileage, purpose, etc.)—keep as long as excess depreciation can be recaptured.

Leased Listed Property: Inclusion amounts may apply (Tables 18–20 in Appendix).

Report on Form 4562. Excess depreciation recapture goes on Form 4797 or Schedule 1.

Appendix: ACRS Percentage Tables (Key Summaries)

Pub 534 includes 20 detailed tables. Highlights:

  • Table 1: 15-year real property percentages (varies by month placed in service).
  • Tables for 18-year & 19-year real property: Year 1 often 7–13% depending on month.
  • Low-income housing: Special accelerated tables.
  • Alternate ACRS tables: Straight-line percentages for elected longer lives.
  • Listed property tables: For non-predominant use or leased property inclusion amounts.

Use the exact table matching your property class and placement date.
