Depreciation on assets question

Potentially allowed, if you pass the tests below

1. Renting has to be your trade or business
   ‍ IRS Publication 946 says rental property doesn’t qualify "if renting property is not your trade or business.".

2. The leasing test
‍If you’re a noncorporate lessor purchased property you lease to tenants generally qualifies only if both of these are true (IRS Publication 946):

the lease term, including any renewal options, is less than 50% of the property’s class life, and
in the first 12 months after the tenant takes the property, your allowable business deductions for 

3. The income limit
‍Your Section 179 deduction can’t be more than your taxable income from the active conduct of any trade or business. You actively conduct a business if you meaningfully participate in its management or operations, and wages count toward the limit. Anything over the limit carries forward to the next year.

4. More than 50% business use
‍You can only elect Section 179 if you use the property more than 50% for business in the year it’s placed in service. If business use falls to 50% or less during the property’s recovery period, you may have to recapture part of the deduction by including it in your taxable income

however, there is a $2,500 De Minimis Exception - it allows expensing an item if these rules are met.:

Under Treasury Reg. §1.263(a)-1(f), the de minimis safe harbor is an IRS rule that treats small‑cost tangible property as a current expense rather than a capital asset. This avoids the paperwork and multi‑year depreciation schedules normally required for long‑life assets.

$2,500 per item or per invoice for taxpayers without an applicable financial statement (AFS) — this covers most freelancers, small businesses, and individual landlords. The limit is per item, not per year — you can expense multiple items under $2,500 each, with no annual cap 

(you do not list them as assets) list under other expenses. In interview mode TurboTax in the asset/ depreciation section for the rental it should ask about these types of items. It’s an annual election that must be included in your 1040. it’s identified as Section 1.263(a)-1(f). It’s automatic.

Section 179 has some oddities. It limited to business income. While the rental property may have a loss Section 179 is limited to business income from all sources. Wages are part of business income.

depending on your tax situation it may or may not be beneficial to take the maximum deductions in the current year especially if you expect higher income in future years. There can also be a limitation on the loss due to the Passive Activity Loss rules. Only real estate professional avoid these. Otherwise you’ll see form 8283 in your return. SDA is not limited to business income so you should be able to expense 100% of the cost despite the rental loss. But again, is this the best in the long run.   

Because you have a net loss, checking the box to elect Section 179 will simply cause the deduction to be capped at $0 for this year and carry forward to future years.

Instead, utilizing 100% Bonus Depreciation (SDA) has no business income limitations. It allows you to claim the entire cost of the furniture and appliances immediately, expanding your 2025 net loss. 

Thanks for the response. Specifically, I’m trying to determine which of the three boxes in both section 179 and SDA to check as there’s a net loss for 2025. The three boxes in each are are similar in terms or taking the maximum, taking a partial or taking no deduction/special depreciation. Which would be most advantageous for subsequent tax years. Thanks
