Business use threshold for Safe Harbor elections?

beaniebop — Wed, 11 Feb 2026 03:40:44 GMT

Let's say I have a computer I use 40% for business and 60% personal. Am I disqualified from expensing the 40% under the safe harbor election?

Does this differ for listed vs unlisted property?

If you use an item for business less than half the time, it won't qualify for Section 179, and you will have to deduct the cost a portion at a time over several years—a process called "depreciation." There is no requirement that you use the computer at least 51% of the time for business to be depreciated.

No, you are not "disqualified" from expensing your 40% business use of your computer; however, for listed property (including a computer) your business use must be more than 50% in order to take a Section 179 expense deduction.

I understand the rules for Section 179 expensing, however I'm asking specifically about the Safe Harbor de Minimis election, which is different. It allows same year expensing of property whose acquisition cost is under $2500 (or $5000 if you have an applicable financial statement).

Also, a computer is no longer considered listed property, but I do understand that it must be used at least 50% for business to qualify for Section 179 expensing

In this IRS document, the $2,500 limit refers to the amount per invoice or item for taxpayers without applicable financial statements.

This applies to the acquisition cost of the item, and not to the part corresponding to its business use.

The de minimis safe harbor election doesn't distinguish between listed and non-listed property.

@MinhT1

Thank you. I'm very aware of those details and my question might be flying over everyone's head so I'll rephrase:

Is there anything in the literature disqualifying the expensing of property that is used less than 50% of the time for business using SAFE HARBOR DE MINIMIS? I am aware I cannot expense the entire cost of anything that is partly used for personal reasons, and I'm well aware of Sectiom 179 rules regarding business use.

What I'm trying to understand is if I can use Safe Harbor election to expense, for example, $250 of a $1000 camera, if the business use is only 25%. Or must it be 100%, or over 50% for business use.

Although the de minimis safe election doesn't specifically mention listed property, chapter 5 of Publication 946 on Listed Property specifically requires that listed property used less than 50% for business be depreciated using the Straight line method over the ADS recovery period.

In your example, a camera is a listed property, and if its business use is less than 50%, it must be depreciated using the Straight line method over the ADS recovery period, and can't be expensed.
