Annual MACRS Depreciation Schedule
Year-by-year tax amortization pursuant to IRS Publication 946.
| Year | Tax Year | Beginning Basis | MACRS Rate % | Depreciation Expense | Accumulated Depr. | Ending Book Value |
|---|---|---|---|---|---|---|
No schedule to run. Section 179 and bonus depreciation together wrote off the full $85,000.00 in year one, so no basis carries into the 5-year recovery period. Reduce the bonus percentage to spread the deduction across later years. | ||||||
Understanding MACRS Depreciation Under IRS Publication 946
The Modified Accelerated Cost Recovery System (MACRS) is the primary tax depreciation system used in the United States. MACRS classifies tangible property into specific recovery classes and applies accelerated depreciation rates that maximize early tax deductions:
Applies to equipment, technology, and vehicles. Uses double-declining balance (200% DB) switching to straight-line when straight-line yields a larger deduction.
Mandatory for 27.5-year residential rental and 39-year nonresidential commercial buildings. Always uses straight-line depreciation with mid-month convention.
How to use this tool
Enter the asset and its cost
Description, unadjusted purchase cost and any Section 179 expensing you are electing.
Set the bonus depreciation rate
Property acquired and placed in service after 19 January 2025 gets 100% bonus under OBBBA s.70301. The old TCJA phase-down rates remain for earlier acquisitions.
Choose the recovery class and convention
Pick the class from IRS Publication 946 (5-year for computers and vehicles, 7-year for machinery, 39-year for commercial property) and the half-year, mid-quarter or mid-month convention.
Read the schedule and export
Deductions are applied in the order the IRS requires: Section 179 first, then bonus, then MACRS on what is left. Export the workpaper as PDF or CSV.
Frequently Asked Questions
What is the order of deductions: Section 179, Bonus, or MACRS?
The IRS mandates a strict sequential order: 1) Section 179 is deducted first from the asset's unadjusted purchase cost; 2) Special Bonus Depreciation is calculated on the remaining basis after Section 179; 3) Regular MACRS depreciation percentages apply to the remaining basis after both Section 179 and Bonus deductions have been subtracted.
Can land be depreciated under MACRS?
No. Land is never depreciable because it does not wear out or become obsolete. When purchasing real estate, you must allocate the total purchase price between the non-depreciable land value and the depreciable building improvements (typically 15%–25% land allocation).
Are my fixed asset records and tax calculations confidential?
Yes, 100%. All IRS Publication 946 lookups, basis reductions, amortization formulas, and PDF workpapers execute strictly inside your local browser memory using client-side JavaScript. Zero tax numbers or corporate asset values are ever transmitted to any remote server.
