The maximum Section 179 deduction for 2023 is $1,160,000. However, there is a spending cap of $4,050,000. This means that if a business purchases $4,050,000 worth of qualifying equipment in 2023, they can only deduct $1,160,000 of that amount in the current year. The remaining $2,890,000 would have to be depreciated over a period of time.
