Can Your Small Business Deduct Inventory Before It Sells?
For a business that purchases merchandise for resale or manufactures products, inventory can tie up cash long before a customer buys anything. Some qualifying small businesses have flexibility in how they account for inventory for federal income tax purposes. But buying inventory does not automatically create an immediate tax deduction.
The usual rule: inventory costs are recovered when goods are sold
Under traditional inventory accounting, costs of merchandise or products are generally carried as inventory and recovered through cost of goods sold when the goods are sold. A purchase that fills your shelves in December may therefore affect taxable income in a later year.
Which businesses may use the small business exception?
For tax years beginning in 2026, the gross receipts threshold is generally $32 million or less in average annual gross receipts over the preceding three tax years. The business must also satisfy the other applicable requirements, including not being a disqualified tax shelter. Related businesses may have to combine their receipts when applying the test. Qualifying businesses can use the small business inventory rules under Internal Revenue Code Section 471(c).
Three ways a qualifying business can account for inventory
1. Nonincidental materials and supplies. Under this method, the cost is generally recovered in the later of the year paid or the year the inventory is used or consumed. Merchandise held for resale is generally treated as used or consumed when sold. Simply purchasing extra products before year end generally will not accelerate the deduction.
2. Applicable financial statement method. A business with an applicable financial statement, or AFS, can follow the inventory treatment reflected in that statement, subject to the tax rules. When the statement capitalizes inventory, this method ordinarily does not allow the business to deduct those costs immediately.
3. Books and records method when there is no AFS. A qualifying business without an AFS may follow the inventory method reflected in its books and records, prepared under its established accounting procedures. If those records properly expense qualifying inventory purchases, the tax method may permit earlier recovery of the costs, subject to payment, accounting method, and other applicable rules. A business cannot simply make a tax-only year end entry that conflicts with how it actually keeps its books.
Example: a year end merchandise purchase
Suppose a qualifying retailer buys $20,000 of merchandise in December and still holds it at year end. Under the nonincidental materials and supplies method, the retailer generally waits until the merchandise is sold to recover the cost. Under a properly adopted non-AFS books and records method that expenses the purchase, the timing may be different. The correct result depends on the retailer’s established books, payment, and tax accounting method, not merely the date on an invoice.
Why the bookkeeping decision matters
A method that accelerates a tax deduction can also change the way inventory and profit appear in internal financial reports. Owners still need reliable inventory counts, purchasing records, and margin information to manage pricing, cash flow, and shrinkage. Tax savings should not come at the expense of knowing whether the business is profitable. Learn about our bookkeeping and payroll services.
Changing methods requires advance planning
An established business cannot ordinarily switch inventory treatment simply by changing a QuickBooks category or choosing a different number on its tax return. A change in tax accounting method generally requires Form 3115, Application for Change in Accounting Method, and may require a Section 481(a) adjustment to prevent income or deductions from being omitted or counted twice. Automatic consent procedures may be available when the requirements are satisfied.
Before changing methods, review the existing inventory balance, how purchases and sales are recorded, whether the business has an AFS, the effects on taxable income in the change year, and whether state tax rules differ. See how proactive tax planning works for business owners.
The bottom line
A small business may have more than one permissible inventory accounting method, and the choice can affect when costs become deductible. The opportunity is not a blanket rule allowing every business to write off unsold merchandise. Review your existing accounting method and financial records before making a year end inventory purchase or changing how your business reports inventory.
