Where do packaging and boxes go on Schedule C?

Updated October 10, 2026 路 Schedule C, Line 22
Short answer Schedule C, Line 22 Supplies

Packaging and shipping boxes belongs on Line 22, supplies.

Why line 22

Plain cartons, mailers, tape and labels used to get an order out of the door are consumed running the business, so they sit on line 22. Packaging that is part of the product as the customer buys it is different: a printed gift box that is part of what a boxed set is, for a business that accounts for inventory, is a cost of that product and belongs in Part III. The deciding question is whether the business produces or resells goods and accounts for inventory. If it does, the cost of anything that becomes part of a product sold belongs in Part III and reaches the return through cost of goods sold, not line 22.

What packaging and shipping boxes is confused with

Part III line 38, part iii line 38, materials and supplies
Packaging that is part of the product as sold, in a business accounting for inventory, is Part III materials and supplies; plain shipping cartons used to post the order are line 22.
Line 18, office expense
The postage and carrier charge itself is office expense on line 18, while the box and tape are supplies on line 22.
Line 27a, other expenses
Many sellers itemise outbound shipping and freight in Part V on line 27a, which is a presentation choice for the carrier cost rather than the packaging.
