How to Calculate MACRS Depreciation


calculate real estate depreciation

The Modified Accelerated Cost Recovery System (MACRS) is the primary method for calculating depreciation for tax purposes in the United States. Introduced by the Tax Reform Act of 1986, MACRS allows businesses to recover the cost of certain assets over time through annual tax deductions. This article will explore the intricacies of MACRS depreciation, explaining its methods, calculations, and providing practical examples.

Understanding MACRS Depreciation


MACRS depreciation is designed to provide larger tax deductions in the early years of an asset’s life, with smaller deductions in later years. This accelerated approach can be beneficial for investors looking to maximize their tax benefits in the short term.


GDS vs. ADS
MACRS encompasses 2 main types of systems:

1. General Depreciation System (GDS): This is the standard method under MACRS, using a combination of declining balance and straight-line depreciation methods.


2. Alternative Depreciation System (ADS): This system uses a straight-line method over a longer recovery period compared to GDS.



Steps to Calculate MACRS Depreciation


Step 1: Determine the Depreciable Basis

The depreciable basis is typically the cost of the asset, including all expenses incurred to make it operational.

  • Purchase price

  • Sales tax

  • Shipping and delivery costs

  • Installation fees

  • Other related expenses

Step 2: Determine the Recovery Period

Step 3: Choose the Depreciation Method and Convention

Step 4: Apply the MACRS Depreciation Rate

Step 5: Calculate Annual Depreciation




MACRS Depreciation Formulas


For the 1st year of depreciation:


Depreciation = Cost x (1 / Useful Life) x Depreciation Method x Depreciation Convention

For subsequent years:


Depreciation = (Cost – Depreciation in Previous Years) x (1 / Recovery Period) x Depreciation Method

Real-World Example Calculation:


Residential Rental Property

Let’s consider a residential rental property with the following details:


  • Purchase price: $275,000

  • Recovery period: 27.5 years (standard for residential rental property under MACRS)

  • Depreciation method: Straight-line (as required for residential real estate)


For this example, we’ll assume the entire $275,000 is for the building (in reality, you would need to subtract the value of the land, which is not depreciable).


Depreciable basis: $275,000


Under MACRS, residential rental property is depreciated using the straight-line method over 27.5 years. The annual depreciation is calculated as follows:



Annual Depreciation Formula


Here’s how the depreciation would look over the first few years:


Year

Annual Depreciation

Accumulated Depreciation

Remaining Basis

1

$10,000

$10,000

$265,000

2

$10,000

$20,000

$255,000

3

$10,000

$30,000

$245,000

4

$10,000

$40,000

$235,000

5

$10,000

$50,000

$225,000

This process continues for the full 27.5-year recovery period.


More to Consider

  1. Mid-Month Convention: In practice, residential rental property is subject to the mid-month convention, which assumes the property was placed in service in the middle of the month. This would slightly adjust the first and last year’s depreciation.


  2. Land Value: In a real-world scenario, you would need to separate the value of the land from the building, as land is not depreciable. This would reduce the depreciable basis.


  3. Tax Implications: The annual depreciation of $10,000 can be deducted from the property owner’s taxable income each year, potentially resulting in significant tax savings.


  4. Depreciation Recapture: When the property is sold, the owner may be subject to depreciation recapture, taxed at a rate of up to 25% on the total amount of depreciation taken over the years.


  5. Cost Segregation: More advanced strategies, such as cost segregation studies, can potentially accelerate depreciation for certain components of the property, leading to larger tax deductions in the early years of ownership.



By using MACRS depreciation, real estate investors can significantly reduce their taxable income over the life of the property, making it a powerful tool for tax planning and wealth building in real estate investment. While the process might seem complex, following these systematic steps makes it manageable. Regular review and proper documentation ensure accurate depreciation calculations and maximum tax benefits.
