Inventory is reported in the financial statements in four places: as a current asset on the balance sheet, as cost of goods sold on the income statement once the goods are sold, as a working-capital adjustment on the statement of cash flows, and in the footnotes that explain the costing method and any write-downs. Each location tells a different part of the story, and the numbers tie together across the statements.
Balance Sheet: Inventory as a Current Asset
Inventory sits in the current assets section of the balance sheet. Under the FASB’s codification, current assets are resources “reasonably expected to be realized in cash or sold or consumed during the normal operating cycle of the business,” and inventory fits that definition because the company plans to convert those goods into cash through sales. It typically appears after cash, cash equivalents, and accounts receivable, following the standard order of liquidity.
The dollar figure represents the total value of finished products, work-in-progress, and raw materials the company holds at the end of the reporting period. That value stays on the balance sheet until the goods are sold or otherwise disposed of. It reflects capital tied up in physical products that have not yet generated revenue. Public companies must follow Generally Accepted Accounting Principles when preparing these figures, and the Securities and Exchange Commission enforces those reporting standards for entities with publicly traded securities.1Accounting Foundation. GAAP and Public Companies
One point often missed: inventory belongs on the balance sheet of whoever controls the goods, not necessarily whoever holds them. In a consignment arrangement, the consignor keeps the inventory on its own balance sheet until the consignee sells it to a customer, because the consignor still bears the risk of loss and price fluctuation.
What Costs Are Rolled Into the Inventory Balance
The number on the balance sheet is not just the purchase price. It includes all direct costs of acquisition, which means the purchase price plus inbound freight and handling. For manufacturers, it also includes production costs.
Absorption Costing for Manufacturers
GAAP requires manufacturers to use absorption costing, so both fixed and variable manufacturing overhead get folded into inventory. Variable overhead, such as factory utilities that fluctuate with production volume, is allocated based on actual use of production facilities. Fixed overhead, such as factory rent or equipment depreciation, is allocated based on the normal capacity of the facility. Leaving overhead out of inventory costs is not an accepted method.
Uniform Capitalization for Tax Purposes
Section 263A of the Internal Revenue Code requires businesses to capitalize certain indirect costs into inventory rather than deducting them immediately.2Office of the Law Revision Counsel. 26 USC 263A – Capitalization and Inclusion in Inventory Costs of Certain Expenses The capitalized costs can include a share of taxes, insurance, and interest on production debt. Interest specifically must be capitalized when it is allocable to property with a long useful life or an estimated production period exceeding two years, or exceeding one year if the cost tops $1,000,000.
Freight-In Versus Freight-Out
Inbound shipping (freight-in) is added to the inventory balance because it is part of the cost of acquiring the goods. Outbound shipping (freight-out) is not; it is recorded as a selling expense on the income statement when the goods leave for the customer. Mixing the two distorts both inventory values and reported profits.
Income Statement: Cost of Goods Sold
When products are sold, their cost moves off the balance sheet and onto the income statement as cost of goods sold. COGS is subtracted directly from revenue to arrive at gross profit. The shift follows the matching principle: expenses tied to producing revenue are recorded in the same period the revenue is earned, so gross margins reflect what it actually cost to generate the sales.
The basic calculation is beginning inventory, plus all costs of goods acquired or produced during the period, minus ending inventory. For a retailer, “costs acquired” is mostly purchases. For a manufacturer, it also includes labor, materials, and allocated overhead. The IRS walks through this same calculation on Schedule C (Form 1040) for sole proprietors, moving from beginning inventory through purchases, labor, and materials to ending inventory and then COGS.3Internal Revenue Service. Publication 334 – Tax Guide for Small Business
Federal tax law requires businesses that produce, purchase, or sell merchandise to use inventories when doing so is necessary to clearly determine income.4Office of the Law Revision Counsel. 26 USC 471 – General Rule for Inventories The implementing regulation states that “inventories at the beginning and end of each taxable year are necessary in every case in which the production, purchase, or sale of merchandise is an income-producing factor.”5eCFR. 26 CFR 1.471-1 – Need for Inventories
Statement of Cash Flows: The Period Change
The statement of cash flows reconciles reported net income with the cash the business actually generated or spent. Under the indirect method, which most companies use, the statement starts with net income and adjusts for items that affected earnings but did not involve cash changing hands.
Inventory changes are one of those adjustments. If inventory rose during the period, the company spent more cash on goods than it recognized as expense, so the increase is subtracted from net income in the operating activities section. If inventory fell, the company sold more than it bought, freeing up cash, so the decrease is added back. These adjustments let readers see whether a business is tying up cash in unsold stock or converting inventory into revenue.
A smaller number of companies use the direct method, which lists actual cash receipts and payments. Under the direct method, the inventory-related line is “cash paid to suppliers,” calculated by combining the change in inventory with the change in accounts payable.
Footnote Disclosures
The dollar figures on the primary statements do not show the accounting choices behind them. That context lives in the footnotes.
Costing Method
Companies must state which inventory costing method they use: first-in, first-out (FIFO), last-in, first-out (LIFO), or weighted average cost. The choice matters because each method produces different profit figures and tax outcomes, especially when prices are moving. FIFO assumes the oldest inventory is sold first, which tends to produce higher reported profits when costs are rising. LIFO assumes the newest inventory is sold first, which can lower taxable income in inflationary periods but leaves older, potentially understated values on the balance sheet. ASC Topic 330 governs these disclosures.6Financial Accounting Standards Board. Inventory (Topic 330) – Simplifying the Measurement of Inventory
Write-Downs
When inventory loses value through damage, obsolescence, or a drop in market prices, the company may need to write it down. The measurement rule depends on the costing method.
For FIFO or average cost, inventory is measured at the lower of its carrying cost or net realizable value, meaning estimated selling price minus costs to complete and sell. If net realizable value falls below cost, the company records a loss.
For LIFO or the retail inventory method, inventory is measured at the lower of cost or “market,” where “market” means current replacement cost, but it cannot exceed net realizable value (the ceiling) or fall below net realizable value minus a normal profit margin (the floor). ASU 2015-11 simplified the measurement for non-LIFO inventory while leaving the older three-tier test in place for LIFO users.6Financial Accounting Standards Board. Inventory (Topic 330) – Simplifying the Measurement of Inventory When a write-down occurs, the footnotes explain the amount and the reason.
LIFO Reserve
Companies using LIFO typically disclose a LIFO reserve, which is the difference between the inventory value under LIFO and what it would be under FIFO. The reserve represents the cumulative tax benefit the company has gained from using LIFO. If a C corporation on LIFO converts to S corporation status, the LIFO recapture amount (the excess of the FIFO value over the LIFO value) must be included in gross income in the corporation’s final tax year as a C corporation.7Federal Register. LIFO Recapture Under Section 1363(d) The footnotes flag the size of the reserve and the potential exposure.
When a Small Business May Not Report Inventory at All
Not every business follows the full set of inventory accounting rules. Section 471(c) of the Internal Revenue Code lets a qualifying small business (other than a tax shelter) either treat inventory as non-incidental materials and supplies, essentially deducting the cost when the items are used or sold, or follow whatever method matches its financial statements or internal books.4Office of the Law Revision Counsel. 26 USC 471 – General Rule for Inventories
To qualify, a business must meet the gross receipts test under Section 448(c). For tax years beginning in 2026, that means average annual gross receipts over the prior three-year period of no more than $32,000,000.8Internal Revenue Service. Revenue Procedure 2025-32 The same threshold exempts these businesses from the uniform capitalization rules under Section 263A.2Office of the Law Revision Counsel. 26 USC 263A – Capitalization and Inclusion in Inventory Costs of Certain Expenses Switching to the simplified method is a change in accounting method and requires following the IRS’s procedures for obtaining consent, so it is not something a business can do informally mid-year.
