What happens to the Section 179 deduction if qualifying property exceeds the threshold amount for the year?

The Section 179 deduction allows taxpayers to deduct the full purchase price of qualifying equipment or software purchased during the tax year, up to a specified limit. However, there is a threshold amount that, when exceeded, impacts the deduction.

When the total cost of qualifying property exceeds this threshold, the amount of the deduction is reduced on a dollar-for-dollar basis. This means for every dollar spent over the threshold amount, the deduction decreases by one dollar. This reduction continues until the deduction reaches zero if enough qualifying property is acquired.

Understanding the mechanics of this deduction is important for tax planning because it encourages small businesses to invest in equipment but also imposes limits to prevent excessive deductions as investment levels rise significantly.

Other answers do not capture the nuances of the law. For instance, the notion that the deduction remains unchanged does not account for the impact of exceeding the threshold. Similarly, stating that the deduction cannot be taken at all is incorrect, as businesses can still receive a reduced deduction based on the level of their investment. The idea of being capped at the maximum deduction available also does not clarify how the deduction is adjusted when the threshold is exceeded.
