Freight capitalization rules require you to add shipping costs to an asset’s cost basis whenever that freight is necessary to bring the asset to the location and condition it needs for its intended use or sale. In plain terms: inbound shipping on inventory becomes part of inventory value, and delivery charges on equipment become part of that equipment’s depreciable basis. The IRS lists freight explicitly as a cost that goes into basis, and treating it as an immediate expense when it should have been capitalized is a change in accounting method the IRS can unwind on you.1Internal Revenue Service. Publication 551 – Basis of Assets
Inbound Freight on Inventory
Freight-in is the cost of moving purchased goods from your supplier to your warehouse. That cost gets added to inventory value on the balance sheet, not expensed on the income statement. IRS Publication 538 defines the cost of purchased merchandise as the invoice price plus “transportation or other charges incurred in acquiring the goods.”2Internal Revenue Service. Publication 538 – Accounting Periods and Methods
The capitalized freight sits inside inventory until the item sells. At that point it moves, along with the rest of the item’s cost, into Cost of Goods Sold. Expensing freight-in immediately overstates costs in the current period and understates them later when the goods actually sell.
The rule sweeps in more than the carrier’s line item. Customs duties, import tariffs, non-refundable sales taxes on the purchase, and in-transit insurance on the goods all belong in inventory cost.
Resellers Versus Manufacturers
A reseller adds freight straight to the cost of purchased items in finished goods inventory. Purchase price plus freight equals capitalized inventory cost, and that’s the end of it.
Manufacturers carry an extra step. Freight on raw materials and components lands first in work-in-process inventory. As production finishes, those accumulated costs move into finished goods, and they hit Cost of Goods Sold only when the finished product ships to a customer. This absorption approach is required under Section 263A for manufacturers and certain resellers.
UNICAP and What It Requires
Section 263A, the Uniform Capitalization Rules, requires you to include both direct and indirect costs in the value of property you produce or acquire for resale.3Office of the Law Revision Counsel. 26 USC 263A – Capitalization and Inclusion in Inventory Costs of Certain Expenses Freight is one of the most common costs the rule catches.
Direct costs are the obvious ones: raw materials, production labor, and the freight that brings materials in. Indirect costs are where businesses get tripped up. Warehouse rent, utilities for a production facility, and portions of administrative overhead tied to production all have to be allocated proportionally into inventory rather than deducted currently.2Internal Revenue Service. Publication 538 – Accounting Periods and Methods
Most inventory-heavy businesses run a UNICAP calculation at year-end, comparing what they actually capitalized against what Section 263A requires. The gap becomes an adjustment to ending inventory.
The Small Business Exemption
Not every business is stuck with UNICAP. Small business taxpayers meeting the gross receipts test under Section 448(c) are exempt from Section 263A’s capitalization requirements.4eCFR. 26 CFR 1.263A-1 – Uniform Capitalization of Costs For tax years beginning in 2026, you qualify if average annual gross receipts over the prior three years do not exceed $32 million.5Internal Revenue Service. Revenue Procedure 2025-32 The threshold adjusts annually for inflation.
Two things to keep in mind. Tax shelters don’t get this exemption regardless of size. And even if you qualify, the underlying principle that direct acquisition costs like freight-in belong in inventory still holds under general accounting rules. The exemption mostly relieves you of allocating indirect overhead, not of capitalizing the shipping charge on your purchases.
Freight on Fixed Assets
Buy a piece of machinery, a vehicle, or office equipment, and the freight to deliver it becomes part of its depreciable basis. Publication 551 lists freight alongside sales tax, installation, and testing as costs included in basis.1Internal Revenue Service. Publication 551 – Basis of Assets The IRS defines basis as “the amount you pay for the asset,” including “other expenses connected with the purchase.”6Internal Revenue Service. Topic No. 703 – Basis of Assets
The capitalized freight isn’t gone. You recover it through depreciation over the asset’s useful life. Pay $50,000 for a machine plus $3,000 to ship it, and your depreciable basis is $53,000.
Every cost required to get the asset to its location and into working condition rides along: site preparation, rigging fees to position heavy equipment, initial testing before the asset goes into service. The dividing line is the moment the asset becomes operational. Costs before that point are generally capitalized; costs after are typically expensed.
Replacement Parts and Upgrades
Shipping costs for parts after an asset is already in service depend on whether the work is a repair or an improvement. The tangible property regulations require capitalizing the full cost, freight included, when the work is a betterment, restoration, or adaptation to a new use.7eCFR. 26 CFR 1.263(a)-3 – Amounts Paid to Improve Tangible Property
A betterment materially increases capacity, productivity, or output, or fixes a pre-existing defect. A restoration replaces a major component or brings a non-functional asset back to working condition. Freight on a part triggering either category gets capitalized with the part.
Routine maintenance is the other side. Shipping a replacement filter or a standard wear-and-tear component is a current expense, because the underlying work isn’t a betterment or restoration.
The De Minimis Safe Harbor
For small purchases, the IRS offers a practical shortcut. Under the de minimis safe harbor election, you can expense tangible property purchases, including any freight, without capitalizing them, as long as the per-invoice or per-item cost stays below the threshold. For businesses with an applicable financial statement (typically an audited one), the ceiling is $5,000 per item. Without one, it’s $2,500 per item.8Internal Revenue Service. Tangible Property Regulations – Frequently Asked Questions
You make the election annually by attaching a statement to your return. It applies to fixed asset purchases, not to inventory, so it won’t spare you from capitalizing freight on goods bought for resale. For an $1,800 printer with $75 shipping, though, the safe harbor lets you expense the full $1,875 rather than depreciate it.
Splitting One Freight Bill Across Many Items
A single freight invoice usually covers dozens of products, and you need a reasonable method to allocate the cost across them. The method matters less than applying it consistently.
- Relative cost: each item absorbs freight in proportion to its purchase price. On a $20,000 shipment with $1,000 in freight, a $100 item picks up $5. This works well when item values vary widely.
- Weight or volume: freight is divided by each item’s share of the physical load. Best when the carrier charges by weight or cubic space, because it tracks the actual cost driver.
- Per unit: the freight bill is split equally across units. Only reasonable when items are similar in size, weight, and value. Applying it to a mixed load of desk lamps and industrial generators badly distorts inventory costs.
Pick a method and use it for all similar shipments through the year. Switching mid-year to move expense into a more convenient period is the kind of inconsistency an auditor will notice.
Outbound Freight Is Different
Outbound freight, the cost of shipping finished goods to a customer, isn’t capitalized. The goods are already complete and salable before the shipping charge is incurred, so seller-paid outbound freight is a period expense, deducted when incurred as a selling or distribution cost. Under FOB shipping point terms the buyer owns the goods on departure and picks up the freight; under FOB destination terms the seller does. Either way, outbound is a cost of completing the sale, not a cost of producing or acquiring the inventory.
What Getting It Wrong Costs You
Mishandling freight capitalization isn’t a rounding problem. The IRS treats a change in how you handle Section 263A costs as a change in accounting method, which triggers a Section 481(a) adjustment.9Internal Revenue Service. IRC 481(a) Adjustment for IRC 263A Accounting Method Changes That adjustment recalculates the cumulative difference between your prior inventory values and the correct ones.
Here’s the painful part. When the IRS initiates the change during an audit, the entire 481(a) adjustment hits in a single tax year. Years of incorrectly expensed freight can pile into one year’s income all at once. A voluntary change, where you correct the error yourself, typically allows a multi-year spread that softens the blow considerably.
Standard accuracy-related penalties can also apply if the IRS finds the misstatement was due to negligence or a substantial understatement of income. The gap between an honest mistake and negligence usually turns on whether you had a reasonable basis for your position and documented it. Given how directly the freight rules are written into Publications 538 and 551 and Section 263A, “we didn’t know” is a hard argument to win.
