For a nonprofit organization, the supplies and materials used to run its programs are the lifeblood of its mission. Whether it's food for a soup kitchen, books for a literacy program, or medical supplies for a free clinic, these tangible items are the direct tools used to serve the community.

Unlike administrative supplies that support overhead, these program materials are a primary operational expense. Understanding how to correctly categorize and track these costs is essential for accurate financial reporting, demonstrating impact to donors, and complying with IRS requirements for tax-exempt organizations. This guide will clarify how to classify these costs based on fundamental accounting and tax principles.

Program Supplies and Materials Category

For a nonprofit organization, the costs of materials and supplies directly used to carry out its mission are a direct Program Expense.

While the provided IRS documents focus on for-profit entities, they establish the principle for deducting these types of costs. IRS Publication 535 states that a business can generally deduct the cost of materials and supplies actually consumed and used during the tax year. 

For a nonprofit, these program supplies are the equivalent of a for-profit's operational supplies and are a primary expense of conducting its business.

Important Considerations While Classifying Program Supplies and Materials

The most critical factor is distinguishing between supplies that directly serve your mission and those that support general administrative functions.

Program Supplies vs. Administrative Supplies

  • Program Supplies (Direct Program Expense): These are items that are directly consumed in the delivery of your nonprofit's services. Examples include food, educational books, medical supplies, or art materials for a youth program.
  • Administrative Supplies (Overhead Expense): These are general office supplies used to run the organization, such as paper, pens, and toner for the administrative office. These are also deductible but are classified as an overhead or administrative expense, not a program expense.

Inventory Rules for Produced Goods

If your nonprofit produces items as part of its program (e.g., a soup kitchen producing meals), the principles of inventory accounting may apply. As detailed in IRS Publication 334, when the production of merchandise is an income-producing factor, you must account for inventory. 

For a nonprofit, this means the cost of the raw materials (like bulk food) would be included in your Cost of Goods Sold to accurately reflect the cost of the meals served.

Tax Implications and Record keeping

To properly account for program supplies, you must report them correctly and maintain meticulous documentation.

How to Report the Expense

While the provided documents focus on for-profit tax forms, nonprofits have their own specific IRS reporting requirements (such as the Form 990 series). On these forms, the cost of program supplies and materials is reported as a direct program service expense. This is a key metric used by the IRS and the public to evaluate how efficiently a nonprofit is using its funds to fulfill its mission.

What Records to Keep

Thorough recordkeeping is essential to substantiate all program expenses. Your records must include:

  • Invoices from all vendors and suppliers for materials purchased.
  • Receipts for any program-related supplies purchased.
  • Proof of payment for all items.
  • Inventory records, if applicable, to track the usage of materials.
