Yes, you can write off shipping costs on taxes when the postage, freight, or carrier fee is paid for a business purpose. The IRS treats these charges like any other operating cost under 26 U.S.C. ยง 162: if the expense is ordinary and necessary for your trade or business, it reduces your taxable income.1Office of the Law Revision Counsel. 26 U.S. Code 162 – Trade or Business Expenses The wrinkle worth knowing before you file: shipping tied to inventory is often deducted later, when the goods sell, not in the year you paid the carrier.
What Qualifies as a Deductible Shipping Cost
Section 162 allows a deduction for “all the ordinary and necessary expenses paid or incurred during the taxable year in carrying on any trade or business.” An “ordinary” expense is common and accepted in your line of work. A “necessary” expense is helpful and appropriate, though it doesn’t have to be indispensable.2Internal Revenue Service. Publication 463 (2025), Travel, Gift, and Car Expenses Mailing products to customers, shipping samples to prospects, and sending contracts by overnight delivery all clear that bar without much argument.
The bright line is business purpose. Shipping a birthday gift to your cousin or moving personal belongings between apartments doesn’t count, no matter which card you swipe. Sole proprietors, freelancers, and e-commerce sellers who blend personal and business shipping on the same carrier account are one audit away from losing the whole batch, because an auditor won’t sort it for you.
Outbound Shipping vs. Inbound Freight
How a shipping charge is classified controls when you get the deduction. This distinction matters more than most owners realize.
Outbound Shipping Is a Current-Year Expense
Shipping that goes out the door to customers or clients is deductible in the year you pay it. That covers postage on invoices, overnight delivery for a client presentation, and carrier charges for sending sold products to buyers. Because these costs aren’t tied to acquiring inventory, they hit your return as an ordinary operating expense.
Inbound Freight Usually Rides With Inventory
When you pay to have inventory shipped to your warehouse or workspace, that freight is added to the cost of the goods themselves. Section 263A requires businesses to capitalize direct costs, and their share of indirect costs, into inventory rather than deducting them immediately.3Office of the Law Revision Counsel. 26 U.S. Code 263A – Capitalization and Inclusion in Inventory Costs of Certain Expenses You don’t write off the freight until the item sells. If 200 units are still in your garage at year-end, the shipping that got them there stays locked in inventory and rolls into the next year.
The Small Business Exemption
Most small sellers don’t have to follow the capitalization rules. Section 263A exempts businesses whose average annual gross receipts over the prior three years fall below an inflation-adjusted threshold. For 2025, that threshold was $31 million.4Office of the Law Revision Counsel. 26 U.S. Code 263A – Capitalization and Inclusion in Inventory Costs of Certain Expenses – Section: Exemption for Certain Small Businesses If you’re under that line, you can use the accounting method you already use for your financial statements, which usually means a simpler treatment of freight. Even so, keep inbound and outbound shipping in separate categories on your books. Clean categorization tells you your real product margins.
Shipping on Business Gifts
Federal tax law caps the deduction for gifts to any one business contact at $25 per person, per year. The favorable news: the cost of mailing or delivering a business gift is treated as an “incidental” expense and does not count against the $25 limit, as long as the shipping doesn’t add substantial value to the gift itself.5eCFR. 26 CFR 1.274-3 – Disallowance of Deduction for Gifts Send a $24 branded box to a client and pay $9 for Priority Mail, and you deduct the full $33.
Standard packaging and transit insurance get the same treatment. Where this breaks down is elaborate custom packaging that effectively becomes part of the gift itself; at that point, an auditor may fold it into the $25 cap.
Mileage and Supplies Count Too
If you drive to the post office, a FedEx drop-off, or a UPS Store for business shipments, that mileage is a separate deduction. For 2026, the IRS standard mileage rate for business driving is 72.5 cents per mile.6Internal Revenue Service. 2026 Standard Mileage Rates Parking fees and tolls along the way are deductible on top of that. Log each trip with the date, destination, and miles driven.
Shipping-adjacent supplies are deductible as well. Packing tape, boxes, bubble wrap, mailers, and printed labels all qualify as ordinary business supplies. These small charges accumulate over a year, and leaving them off the return is money left behind.
Military PCS Moves: A Narrow Exception
The moving expense deduction was eliminated for most taxpayers after 2017. Active-duty military members who relocate under a permanent change of station order can still deduct unreimbursed moving and shipping costs, including packing, crating, in-transit storage, and insurance for household goods and personal effects.7Internal Revenue Service. Instructions for Form 3903 A PCS covers three situations: moving from home to a first post of active duty, transferring between permanent posts, and moving from a last post back home after service ends. Costs the government already covered or reimbursed through a non-taxable allowance can’t be claimed again. For foreign moves, deductible costs expand to include storage of household goods for part or all of the overseas assignment. These expenses are reported on Form 3903 and flow through as an above-the-line deduction, so you don’t need to itemize.
Where to Report Shipping Costs
The form depends on your business structure, but the underlying deduction is the same.
Sole Proprietors and Single-Member LLCs
Report business income and expenses on Schedule C of Form 1040.8Internal Revenue Service. About Schedule C (Form 1040), Profit or Loss from Business (Sole Proprietorship) Outbound shipping and general postage go on Line 18, which covers office expenses including postage.9Internal Revenue Service. Instructions for Schedule C (Form 1040) (2025) If your freight costs feel distinct from “office expenses,” list them separately in Part V (Other Expenses) on Line 48 with a description like “shipping and freight.” Either works, as long as you don’t double-count.
Inbound freight tied to inventory goes in Part III of Schedule C, which calculates Cost of Goods Sold. Putting freight-in there adjusts gross profit correctly so the deduction lands in the period the goods sell.
S-Corporations and Partnerships
S-corporations report on Form 1120-S. Freight tied to inventory feeds into Line 2 (Cost of Goods Sold), while outbound shipping and postage typically go on Line 20 (Other Deductions) with an attached itemized statement.10Internal Revenue Service. Instructions for Form 1120-S (2025) Partnerships follow the same logic on Form 1065, with operating shipping treated as an ordinary business deduction that flows through to each partner’s Schedule K-1.
Records That Hold Up
Carrier receipts are the backbone of any shipping deduction. Save every invoice, confirmation email, and digital receipt from USPS, FedEx, UPS, and any other carrier. Each record should show the amount, the date, and enough detail to connect the shipment to a business purpose. A bank or credit card statement alone usually isn’t enough, because it shows a charge but not what shipped or why.
Log each shipment as it happens in accounting software or a spreadsheet, and keep inbound freight separated from outbound postage. Retroactively sorting a year of receipts in April is miserable and error-prone.
The IRS requires you to keep records supporting a deduction for at least three years after filing the return, or two years from the date you paid the tax, whichever is later.11Internal Revenue Service. How Long Should I Keep Records? Holding shipping records for four years is cheap insurance.
Mistakes That Cost You the Deduction
The rules are generous, but small errors chip away at the benefit. Mixing personal and business shipping on one carrier account is the most common problem, and it can sink an entire year of deductions in review.
Deducting inbound freight as an operating expense when it should be capitalized into inventory is the next most frequent misstep. For businesses above the gross receipts threshold, this timing difference can trigger an adjustment and back taxes. For businesses below the threshold, it still distorts product margins.
Finally, don’t forget the small stuff. Packing materials, tape, boxes, bubble wrap, and shipping labels are business supplies. Skipping them on the return leaves real money behind.
