How much could I deduct?

These are the limits:

You cannot write off more than $1,220,000.

The total amount of the equipment purchase cannot be more than $3,050,000. It phases out dollar-for-dollar after that, so once $4,270,000 is spent, the deduction goes away entirely.

Section 179 highlights

Section 179 allows qualifying businesses to deduct up to the full purchase price of certain new or used vehicles, equipment and/or software purchased and placed into service during the tax year.

To qualify, the percentage of business use for the vehicle, equipment or software must be more than 50%.
