Can you write off Amazon returns if the item was for business testing?

Generally, if you bought an Amazon item for legitimate business testing and then received a full refund, you usually can’t deduct the refunded amount. For tax purposes, you normally deduct only your net out-of-pocket business cost.

So if the item was fully refunded, the deductible cost for that item is usually $0.

What you may still be able to deduct:

• Return shipping, restocking, or other nonrefunded fees you actually paid, if they were for a business purpose.
• Items that were damaged, consumed, destroyed, or otherwise could not be returned during the business testing process, if your facts support treating the purchase as a business expense.

Bookkeeping-wise, the clean approach is usually to record the purchase as a business expense and then record the refund as an offset or credit when it comes back.

If the purchase and refund happen in different tax years, the treatment can be more technical and may depend on your accounting method and the tax rules that apply. In some cases, a later refund may need special tax treatment under the tax benefit rule, so it’s worth checking the IRS guidance or a tax professional before filing.

Tax situations can vary by business structure, location, and how the testing expense is categorized.
