Definition of
Modified Accelerated Cost Recovery System (MACRS)

What is MACRS? The Modified Accelerated Cost Recovery System (MACRS) is the current tax depreciation system used in the United States for most tangible assets placed in service after 1986. Mandated by the IRS, MACRS allows businesses to recover the capitalized cost of eligible property over a specified recovery period through annual deductions. It typically allows for larger depreciation deductions in the early years of an asset's life (accelerated depreciation) compared to straight-line depreciation often used for financial accounting under GAAP.

The Importance of
MACRS
Understanding and correctly applying MACRS is important for businesses as it directly impacts their taxable income and tax liability. By allowing accelerated depreciation, MACRS can provide larger tax deductions in the early years of an asset's life, improving cash flow during those periods. This can be particularly beneficial for businesses making significant investments in new equipment or property. Proper application of MACRS rules is essential for accurate tax compliance and avoiding potential issues with the IRS. It is distinct from depreciation methods used for book purposes (GAAP), which means businesses often maintain two sets of depreciation records.
