Can My LLC Deduct a $180,000 Machine in 2026?

Name: Can My LLC Deduct a $180,000 Machine in 2026?
Uploaded: 2026-10-16
Description: The LLC can deduct the full $180,000 machine cost for 2026 using 100% bonus depreciation, assuming the machine qualifies and is used entirely for business.

Checked 2026-10-16 with ChatCPA Second Opinion: three AI models answered, every citation was checked against the official text, and a challenger tried to break the answer.

The LLC can deduct the full $180,000 machine cost for 2026 using 100% bonus depreciation, assuming the machine qualifies and is used entirely for business. Placing it in service in December does not reduce that deduction. Both the October contract and November purchase are after the applicable January 19, 2025 cutoff.

Bonus depreciation is generally the better federal choice for a full write-off. Section 179 could also deduct $180,000, but it depends on business income limits at both the LLC and partner levels. Its 2026 maximum is $2,560,000, with the limit reduced when total qualifying purchases exceed $4,090,000. If both methods allow the full deduction, choosing one over the other produces $0 difference in the current federal deduction.

The preparer should check state tax treatment, the machine’s eligibility and business use, and each partner’s ability to use any resulting loss. Section 179 may be preferable if state treatment favors it or the LLC wants to expense only part of the cost. The LLC’s deduction does not necessarily mean every partner can use their share immediately.

The memo, with red lines

The LLC can deduct the full $180,000 for 2026 using 100% bonus depreciation¹, assuming the machine is eligible property, its depreciable cost is $180,000², and it is used entirely for business. December placement in service does not prorate the deduction. Both the October 2026 contract and November purchase fall after the January 19, 2025 acquisition cutoff³.

Bonus depreciation is generally the better federal choice for a full write-off because it is not subject to section 179’s business income limit. Section 179 could also expense $180,000 if the applicable limits permit: the 2026 maximum is $2,560,000, reduced when total qualifying investment exceeds $4,090,000⁴, and the business income limit applies at both the partnership and partner levels⁵. If both methods permit the full deduction, the difference in the current federal deduction is $0, so neither produces an additional current federal tax saving over the other under otherwise identical circumstances.

Section 179 may be preferable for selective expensing or favorable state tax treatment. The preparer should confirm the machine’s eligibility, business use, state treatment, and partner-level loss restrictions before choosing. The LLC’s deduction does not guarantee immediate use by its partners: partnership-interest basis⁶, at-risk⁷, passive-loss, and excess-business-loss limits may defer their deductions.

Authority	Cited by	Result	What the source says
IRC §168(k)(1)	3 of the AI answers	Confirmed	Section 168(k)(1) provides an allowance equal to 100% of qualified property’s adjusted basis for the taxable year it is placed in service. This citation alone does not determine whether this machine qualifies or whether bonus depreciation or section 179 is preferable.“an allowance equal to 100 percent of the adjusted basis of the qualified property” Source
IRC §168(k)(2)(A)	1 of the AI answers	Confirmed	The cited provision defines qualified property to include property subject to §168 with a recovery period of 20 years or less, subject to the additional original-use or acquisition requirements. It does not itself resolve the deduction amount or whether bonus depreciation or §179 is preferable.“to which this section applies which has a recovery period of 20 years or less” Source
Notice 2026-11	3 of the AI answers	Partly right	The text supports the acquisition-date test and the written-binding-contract rule, but it does not state that the bonus depreciation rate is 100%.“property is not treated as acquired after the date a written binding contract is entered into” Source
Treas. Reg. §1.1012-1(a)	2 of the AI answers	Confirmed	The regulation generally defines property’s basis as its cost, supporting the stated $180,000 starting basis, though it does not determine the final depreciable basis or the 2026 deduction.“In general, the basis of property is the cost thereof.” Source
Rev. Proc. 2025-32, §4.24	1 of the AI answers	Confirmed	The procedure sets the 2026 §179 maximum at $2,560,000 and reduces it by the amount qualifying property placed in service exceeds $4,090,000.“cannot exceed $2,560,000” Source
Treas. Reg. §1.179-2(c)	2 of the AI answers	Confirmed	The regulation defines the section 179 taxable-income limitation and says it applies to both the partnership and each partner. It does not determine the machine’s total 2026 deduction or whether bonus depreciation is preferable.““The taxable income limitation of this paragraph (c) applies to the partnership as well as to each partner.”” Source
IRC §704(d)	1 of the AI answers	Confirmed	Section 704(d) limits a partner’s distributive share of partnership loss to the adjusted basis of the partner’s interest at year-end, commonly called outside basis.“shall be allowed only to the extent of the adjusted basis of such partner’s interest in the partnership” Source
IRC §465(a)	1 of the AI answers	Confirmed	IRC §465(a) limits losses from covered activities to the taxpayer’s amount at risk. The claim accurately summarizes the provision, though it does not address the machine’s depreciation deduction or which depreciation method to use.“any loss from such activity for the taxable year shall be allowed only to the extent of the aggregate amount with respect to which the taxpayer is at risk” Source
IRS Topic No. 704	1 of the AI answers (incl. the challenger)	Confirmed	IRS Topic No. 704 exists and states that the special depreciation allowance is 100% for qualified property acquired and placed in service after January 19, 2025. The claim is accurate, subject to the property meeting the qualification rules.“For qualified property acquired and placed in service after January 19, 2025, the special depreciation allowance is 100%.” Source
