Can Resellers Deduct Shipping Costs on Taxes?

A $9 shipping label can feel like a pass-through cost when you sell on Whatnot. For tax purposes, it is still a business transaction that needs the right treatment. So, can resellers deduct shipping costs? In many cases, yes. But the answer changes depending on whether you paid to ship an order to a customer, paid to bring inventory into your business, or were reimbursed by the buyer.

The practical goal is simple: record shipping costs consistently so your profit reports reflect reality and your tax return is supported by clean records. Shipping should not disappear into a single mystery number alongside platform fees and inventory purchases.

Can resellers deduct shipping costs as a business expense?

Most resellers can deduct ordinary and necessary shipping expenses connected to operating their business. For a Whatnot seller, that commonly includes postage or carrier labels used to send sold items to buyers, as well as shipping supplies such as boxes, tape, bubble wrap, mailers, labels, and packing paper.

An expense is generally ordinary if it is common in your line of business, and necessary if it is helpful and appropriate for the business. Sending sold inventory to customers clearly meets that practical standard for most online resellers.

If you buy a UPS, USPS, FedEx, or other carrier label to fulfill an order, the amount you paid is generally a deductible business shipping expense. The same is usually true when a marketplace deducts shipping-related charges from your payout before you receive it.

That said, a deduction does not mean shipping is free. It reduces taxable business income, not the full cash cost. If your combined federal and state tax rate is 25%, a $20 deductible shipping expense may reduce your tax bill by roughly $5. You still need enough margin in the sale to cover the other $15, plus inventory cost, fees, and labor.

Outbound shipping versus shipping inventory to you

The biggest point of confusion is that not every shipping cost is handled the same way.

Outbound shipping to customers

Outbound shipping is what you pay to get a sold item from your business to the buyer. This is commonly treated as a current operating expense. A label purchased after a Whatnot sale is the cleanest example.

You may track it as shipping expense, delivery expense, postage, or fulfillment expense. The exact account name matters less than using one method consistently and retaining supporting records.

Inbound shipping on inventory purchases

Inbound shipping is what you pay to receive inventory before you sell it. For example, you might pay $200 for a vintage collection plus $35 freight to have it sent to you.

That $35 is often part of your inventory cost rather than a separate current shipping deduction. In accounting terms, it is commonly called freight-in. You generally recover the cost through cost of goods sold when the inventory is sold.

This distinction matters because expensing inbound shipping immediately can make a period look less profitable than it really is, while overstating profit later when the item sells. Smaller businesses may have tax-accounting options that simplify inventory treatment, so this is a good item to confirm with a qualified tax professional who understands your business and filing method.

Shipping for returns, repairs, and business operations

Other shipping costs can also be deductible when they are business-related. That may include return labels you provide to buyers, freight to send an item for authentication or repair, shipping samples to a potential wholesale buyer, or mailing tax documents and business correspondence.

The business purpose is what matters. Personal postage, personal moving costs, or shipping unrelated items should stay out of your business books.

What if the buyer pays for shipping?

A buyer-paid shipping charge does not automatically make your shipping-label cost nondeductible. In many cases, you report the money received from the customer as revenue and record the label you purchased as a shipping expense. The two entries may offset each other, but they should not be ignored.

Here is a simple example. You sell an item for $40 and the buyer pays $8 for shipping. Your gross receipts for that transaction may be $48. If you pay $8 for the carrier label, you record an $8 shipping expense. If the label costs $10 instead, you record the full $10 expense, and the extra $2 comes out of your margin.

Marketplace payout reports can make this harder to see because the platform may collect buyer shipping, create the label, and show only net proceeds. Do not assume the deposit that reached your bank account tells the full story. Reconcile the order-level details, including sale price, shipping collected, shipping paid, seller fees, payment processing, refunds, and adjustments.

This is where sellers often underreport income or miss expenses. Both mistakes create problems: one can increase tax unnecessarily, while the other can leave records that do not match marketplace reporting.

Keep records that prove the expense

You do not need an elaborate paper filing system, but you do need records that connect shipping costs to your business. A carrier receipt alone is useful. A receipt tied to an order, date, and customer sale is far better.

For each shipping transaction, retain the carrier or marketplace record, date, amount paid, tracking number or order reference, and a clear business purpose. Keep receipts for packing supplies, too, especially when buying in bulk at a store or online.

Your bookkeeping should separate at least three categories: outbound shipping labels, shipping and packing supplies, and inbound freight on inventory. That separation gives you a truer view of what it costs to fulfill orders versus what it costs to acquire stock.

Avoid using bank transactions as your only record. A bank feed may show a single marketplace charge or a bulk carrier purchase without explaining which sales it covered. It is a useful cross-check, not a complete profit-and-loss system.

A practical workflow for Whatnot sellers

Start by deciding how you will record shipping before your next live show, rather than trying to reconstruct hundreds of orders in January. Import or capture each Whatnot earnings statement, then review the shipping-related fields alongside seller fees and refunds.

Next, make sure your inventory cost includes any inbound freight when appropriate. When you sell an item, match its sale to the related fulfillment cost so you can see the actual order margin. A $50 sale is not a $50 win if it carried $12 in shipping, $7 in fees, and $20 in inventory cost.

Finally, reconcile your reports to your bank activity on a regular schedule. Weekly works well for active sellers. Monthly is the minimum for most businesses with consistent volume. The longer you wait, the harder it is to identify whether a charge was a customer label, inventory freight, a return, or something personal.

Whatprofits is built by a Whatnot seller, for Whatnot sellers, and helps turn marketplace earnings data, seller fees, shipping costs, expenses, and inventory margins into a usable profit view. The point is not just cleaner tax records. It is knowing whether each show and each category is actually paying you.

When you should ask a tax professional

Shipping is straightforward for many sellers, but get advice tailored to your situation if you have high inventory volume, use different accounting methods, sell across states, import goods, collect sales tax, or file as an entity such as an S corporation or partnership. These factors can change how inventory and related freight should be reported.

You should also ask for help if your marketplace forms, bookkeeping reports, and bank deposits do not reconcile. Trying to force them to match by deleting expenses or treating every deposit as sales income can create a bigger cleanup job later.

The useful standard is not whether a cost sounds deductible. It is whether the shipping charge was genuinely business-related, accurately classified, and supported by records. Get that right throughout the year, and tax time becomes a reporting task instead of a margin-killing guessing game.
