QBO Category: > **Behind on your bookkeeping?** Ketchup catches up your QuickBooks in 3–7 business days — starting · Line 13

Quick Answer: ✅ Yes — Machinery used in business can be depreciated over its useful life or immediately expensed under Section 179 (up to limits).

The Short Answer

Business machinery is deductible, but the method depends on the cost and your choice of tax strategies. You can either: (1) depreciate the machinery over its useful life (typically 5-7 years for most equipment), (2) immediately expense it using Section 179 deduction (up to $1.23 million in 2024), or (3) use bonus depreciation for qualified property. Most small businesses benefit from immediate expensing under Section 179.

IRS Rules for Deducting Machinery

Under IRC Section 167, business machinery is depreciable property with a useful life determined by IRS guidelines (typically 5-7 years for most machinery under MACRS). However, IRC Section 179 allows immediate expensing of qualifying machinery up to annual limits ($1.23 million for 2024, $1.29 million for 2025). IRC Section 168(k) provides bonus depreciation for new equipment. IRS Publication 946 (How to Depreciate Property) covers all depreciation methods and elections.

How Much Can You Deduct?

Machinery Cost	2024 Section 179 Limit	2025 Section 179 Limit	Alternative
---------------	----------------------	----------------------	-------------
Up to $1.23M	✅ 100% immediate	✅ 100% immediate	Or depreciate over 5-7 years
$1.23M - $3.05M	Phased out	Phased out	Depreciate or bonus depreciation
Over $3.05M	Must depreciate	Must depreciate	MACRS depreciation

Section 179 phases out dollar-for-dollar once equipment purchases exceed the threshold ($3.05M in 2024, $3.22M in 2025).

How to Categorize in QuickBooks

QBO Category: Equipment or Fixed Assets (then depreciate) OR Equipment Expense (if Section 179)
Schedule C Line: Line 13 (Depreciation) for traditional depreciation, or appropriate expense line for Section 179
Tip: Work with your accountant to decide between Section 179 and depreciation. Section 179 gives immediate tax savings but uses up current-year deduction capacity. Depreciation spreads the benefit over multiple years.

Common Mistakes to Avoid

Not considering Section 179 for equipment purchases. Many small businesses can immediately expense machinery rather than depreciating it over 5-7 years. This provides immediate tax savings.
Missing the business use requirement. Machinery must be used more than 50% for business to qualify for Section 179 or bonus depreciation. Personal use reduces the deductible percentage.
Not planning equipment purchases for tax timing. Section 179 and bonus depreciation can create large deductions in the purchase year. Plan timing based on your income and tax situation.

Record-Keeping Requirements

Maintain equipment purchase invoices and receipts, delivery and installation documentation, records of business use percentage if mixed use, Form 4562 (Depreciation and Amortization) for tax filings, and for Section 179, documentation supporting business use requirements. Keep detailed records for the entire life of the equipment plus 3 years.
