Where do print on demand supplies go?

Updated October 10, 2026 路 Part III line 38
Short answer Part III line 38 Part III line 38, materials and supplies

Printing consumables for a print on demand seller belongs on Part III line 38, part iii line 38, materials and supplies.

Why part iii line 38

If you print the items yourself, the blanks, ink, film, transfer paper and adhesive become the product the customer buys, so their cost is Part III materials and supplies and reaches the return through cost of goods sold rather than line 22. Line 22 says in terms that it is for supplies not included in Part III, and this is the case it is excluding. A small business taxpayer under the gross receipts test may treat inventory as non incidental materials and supplies and deduct it when the item is sold or used, which changes the timing but still reports it in Part III. A seller who holds nothing and only pays a fulfilment partner per order is paying for a finished good, which is a Part III purchase on line 36.

Line 22, supplies
Line 22 is for supplies consumed running the business that do not become a product, so a service business with no goods sold uses line 22 while a seller printing merchandise uses Part III.
Part III line 36, part iii line 36, purchases less personal use
Blanks and finished items you buy in ready to sell are purchases on Part III line 36, while the ink and film you consume turning them into the product are materials and supplies on line 38.
Line 13, depreciation and section 179 expense deduction
The printer, heat press and cutter last more than a year and are capital assets reaching line 13, not costs of goods.

Examples that belong on part iii line 38

What does not belong here

The limit that applies

A small business taxpayer meeting the gross receipts test can treat inventory as non incidental materials and supplies, deductible when sold or used, instead of keeping full inventory accounting. The threshold is indexed and set each year.

What to keep

Keep the purchase invoices and a year end count of unsold stock, because cost of goods sold is a calculation from opening stock, purchases and closing stock. Without the counts the Part III figure cannot be supported.
