Business owners often assume that every piece of equipment they purchase must be depreciated over several years. That is not always true.

The Internal Revenue Code and Treasury Regulations contain a separate set of rules governing materials and supplies, allowing many inexpensive or short-lived items to be deducted immediately as ordinary business expenses.

Understanding these rules can simplify bookkeeping while helping businesses remain compliant with IRS regulations.

What Are Materials and Supplies?

Treasury Regulation § 1.162-3 defines materials and supplies generally as tangible property that is consumed in business operations or has only a short useful life.

The regulation provides in part:

“Materials and supplies means tangible property that is used or consumed in the taxpayer’s operations and that is not inventory…”
Treas. Reg. § 1.162-3(c).

The regulation then identifies several categories of property that qualify.

Property Costing $200 or Less

One category includes tangible property costing $200 or less.

Treasury Regulation § 1.162-3(c)(1)(iv) provides:

“A unit of property that has an acquisition or production cost of $200 or less.”

This provision means many inexpensive business items never have to be depreciated at all.

Examples include:

• Basic hand tools
• Office supplies
• Small computer accessories
• Flashlights
• Tape measures
• Extension cords
• Safety equipment
• Low-cost replacement parts

Property With a Useful Life of 12 Months or Less

The regulations also include certain property expected to be consumed within one year.

Treasury Regulation § 1.162-3(c)(1)(iii) includes:

Property with an economic useful life of 12 months or less beginning when first used in the taxpayer’s business.

Examples might include:

• Disposable protective equipment
• Temporary construction materials
• Certain testing supplies
• Short-lived production items

Deduction When Used or Consumed

Unlike inventory, materials and supplies are generally deducted when they are first used or consumed in the business.

Treasury Regulation § 1.162-3(a)(1) generally provides that taxpayers deduct the cost of non-incidental materials and supplies in the taxable year in which they are first used or consumed in their operations.

This timing rule is important because purchasing an item does not always create an immediate deduction.

This Is Different From the De Minimis Safe Harbor Election

Many taxpayers confuse these rules with the De Minimis Safe Harbor Election.

Although both may produce immediate deductions, they are different provisions.

Materials and Supplies (Treas. Reg. § 1.162-3)

• Applies automatically if the requirements are met.
• Focuses on the nature and cost of the property.
• Does not require the annual de minimis election.

De Minimis Safe Harbor (Treas. Reg. § 1.263(a)-1(f))

• Is a separate annual tax election.
• Allows larger qualifying purchases to be deducted, subject to applicable dollar limits and documentation requirements.
• Depends upon compliance with specific regulatory requirements.

Common Mistakes

Some of the most common errors include:

• Depreciating inexpensive property that qualifies as materials and supplies.
• Deducting non-incidental materials before they are actually used or consumed.
• Confusing inventory with materials and supplies.
• Assuming every purchase under a certain dollar amount automatically qualifies.

Each category has its own rules, and proper classification matters.

Final Thoughts

For many small businesses, understanding Treasury Regulation § 1.162-3 can simplify tax reporting while avoiding unnecessary depreciation schedules. The regulation provides a practical framework for deducting many low-cost and short-lived business items without resorting to more complex capitalization rules.

Because these rules interact with inventory accounting, capitalization regulations, and the de minimis safe harbor election, taxpayers should carefully evaluate how each purchase should be treated before preparing their returns.
