Frequently Asked Questions
What is depreciation?
Depreciation is the accounting method of allocating the cost of a tangible asset over its useful life. It represents how much of an asset's value has been used. Depreciation is a non-cash expense that reduces taxable income while preserving cash flow.
What is MACRS depreciation?
MACRS (Modified Accelerated Cost Recovery System) is the IRS-required tax depreciation method for most business assets. It uses predetermined rates and recovery periods (3, 5, 7, 10, 15, 27.5, or 39 years). MACRS uses accelerated methods with built-in salvage value of $0.
What is the difference between book and tax depreciation?
Book depreciation (GAAP) uses methods like straight-line for financial statements, reflecting economic reality. Tax depreciation (MACRS) follows IRS rules for tax returns, often accelerating deductions. Companies maintain two sets of depreciation records.
What is salvage value?
Salvage value (residual value) is the estimated value of an asset at the end of its useful life. It's the amount you expect to receive when selling or disposing of the asset. MACRS ignores salvage value, but GAAP methods use it to calculate depreciable basis.
Which depreciation method should I use?
For taxes: Use MACRS (required by IRS). For financial reporting: Straight-line is most common and easiest. Accelerated methods (declining balance, sum-of-years) front-load deductions for assets that lose value quickly. Choose based on asset usage pattern.
