Quick Answer: 🔄 It Depends — Raw materials are typically included in Cost of Goods Sold (COGS), not directly deducted as expenses. You deduct the cost of materials when the finished products are sold.
The Short Answer
Raw materials used to manufacture products are generally not immediately deductible as business expenses. Instead, they're part of your Cost of Goods Sold (COGS), which reduces your taxable income when the finished products are sold. If you buy $10,000 in raw materials but only use $6,000 worth in products sold this year, only the $6,000 is deductible. The remaining $4,000 stays in inventory until used.
IRS Rules for Deducting Raw Materials
Under IRC Section 471 and IRS Publication 538 (Accounting Periods and Methods), businesses that produce or purchase goods for sale must use inventory accounting. Raw materials are capitalized as inventory assets and expensed through COGS when the finished products are sold. Treasury Regulation §1.471-1 requires this treatment for businesses with average gross receipts over $29 million in the prior 3 years. Smaller businesses may elect to expense materials when purchased under the "small business exemption" of IRC Section 448(c).
How Much Can You Deduct?
| Business Size | Treatment | Deduction Timing |
| -------------- | ----------- | ------------------ |
| Gross receipts <$29M (3-year avg) | ✅ May expense when purchased | Immediate |
| Gross receipts ≥$29M (3-year avg) | Must capitalize as inventory | When products are sold |
| Custom manufacturers (made to order) | ⚠️ May qualify for immediate expensing | Project completion |
| Service businesses using materials | ✅ Usually deductible when used | When used |
The small business exemption allows many manufacturers to deduct raw materials immediately rather than tracking inventory.
How to Categorize in QuickBooks
- QBO Category: Cost of Goods Sold — Raw Materials or Inventory Asset (depending on method)
- Schedule C Line: Part III (Cost of goods sold) — not directly on expense lines
- Tip: If you qualify for the small business exemption, you can set up raw materials as a COGS account that flows through immediately rather than tracking ending inventory. Consult your accountant about the best method for your situation.
Common Mistakes to Avoid
- Treating raw materials as regular business expenses. Unless you qualify for the small business exemption, raw materials must be capitalized as inventory and expensed through COGS.
- Not tracking inventory properly. If you're required to use inventory accounting, you need beginning inventory + purchases - ending inventory = COGS. Failing to track ending inventory correctly affects your tax liability.
- Mixing direct materials with supplies. Raw materials that become part of your product are inventory. General supplies (office supplies, cleaning materials, small tools) are immediately deductible expenses.
Record-Keeping Requirements
Maintain purchase invoices for all raw materials, inventory tracking records (beginning/ending quantities and values), production records showing materials used in specific products, vendor statements and delivery receipts, and for businesses using inventory accounting, year-end physical inventory counts. The IRS may examine inventory accounting methods during audits.
Who Can Deduct Raw Materials?
- Sole proprietors: Include in COGS on Schedule C, Part III (or immediate expense if qualifying for small business exemption)
- LLCs: Same treatment as sole proprietors based on size and election
- S-Corps: Must follow inventory accounting rules based on size
- C-Corps: Must follow inventory accounting rules based on size
- Nonprofits: If producing goods for sale, same inventory rules apply
