I bought a new computer in 2025 to be used in my business. My business is showing a loss this year. How do I determine which method is best for me (Special Depreciation Allowance or partial Section 179)? FYI, the computer was under $5,000 and I use it more than 50% for my business. Help is appreciated. Make it a great day.

Since your business is running at a loss this year, the Section 179 deduction is likely not the best choice because it is limited by your business income. According to the tax code, the amount allowed as a Section 179 deduction cannot exceed your amount of taxable income from conducting your business.

The Special Depreciation Allowance (SDA), on the other hand, does not have the taxable income limitation, which means you can fully expense the computer and increase your business loss for the year, which could be carried forward as a Net Operating Loss.

Alternatively, because your computer was under $5,000, you may be able to bypass the depreciation and Section 179 rules by simply choosing to expense the computer using the de mimimus safe harbor method for tangible property. This election allows you to immediately deduct the cost of the computer as an ordinary business expense. However, most small businesses only qualify for up to $2,500 because they do not have an "applicable financial statement". If you have a large corporation with an applicable financial statement, then the amount would increase to $5,000.

Therefore, if your computer cost $2,500 or less, use the de minimis safe harbor method and expense it. Otherwise, opt for the SDA.
