Tax answers · IRC §179
Can You Deduct The Full Cost Of Business Equipment?
Section 179 may allow an immediate deduction for qualifying business property instead of recovering its cost over several years. Eligibility, business use, annual limits, and business income can restrict the deduction. Section 179 and bonus depreciation are different provisions.
Buying Is Only Part Of The Timing Question
The property generally must be placed in service: ready and available for its intended business use. An order, deposit, or unopened purchase is not by itself the same thing. Keep the delivery, installation, and use dates with the invoice.
Check Business Use And The Type Of Property
Mixed-use property requires a business-use calculation. Section 179 generally requires more than 50% business use, and a later reduction can cause recapture. Vehicles and other listed property have additional rules; a headline about a large deduction is not a vehicle-specific answer.
Compare The Methods Before Electing
Consider Section 179, any available bonus depreciation, and regular depreciation together. The deduction you can claim, the deduction you elect, and the best timing for your situation can differ. Confirm the limits and acquisition-date rules for the tax year involved.
What To Gather Before The Conversation
- Invoice and financing documents
- Placed-in-service date
- Business-use support
- Prior depreciation schedules and current income estimate
