What is MACRS depreciation?
MACRS (Modified Accelerated Cost Recovery System) is the current tax depreciation method required by the IRS for most business and investment property. It allows businesses to deduct the cost of tangible assets over a specified recovery period using declining balance methods. MACRS provides larger deductions in the earlier years, which accelerates tax benefits.
What is Section 179?
Section 179 allows businesses to deduct the full purchase price of qualifying equipment and software in the year it is placed in service, rather than depreciating it over time. For 2026, the maximum Section 179 deduction is $2,560,000, with a phase-out threshold beginning at $4,090,000 in total purchases. This applies to new and used equipment.
What is bonus depreciation in 2026?
Bonus depreciation allows businesses to take a large first-year deduction on qualifying assets. The One Big Beautiful Bill Act (OBBBA) permanently restored 100% bonus depreciation for qualifying property placed in service on or after 20 January 2025, so the old TCJA phase-down (60% in 2025, 40% in 2026) no longer applies. It applies to the cost remaining after Section 179 and can be used on new and used assets.
What are recovery periods?
Recovery periods determine how many years an asset is depreciated. Common periods include: 3 years for racehorses and tractor units; 5 years for automobiles, computers, and office equipment; 7 years for office furniture and most manufacturing equipment; 15 years for land improvements; 27.5 years for residential rental property; and 39 years for commercial buildings.
IRS-Aligned: MACRS rates and Section 179 limits reflect IRS Publication 946 for the 2026 tax year. Bonus depreciation follows the TCJA phase-down schedule. Consult a tax professional for complex asset situations.
