Retail Product at the Booth 2026: A Hairstylist's Schedule C Fork — Part III, Line 22, or No COGS

§1One job, one tax year, one fork

The job is booth renter: a hairstylist who rents a chair, collects her own client payments, and keeps a shelf of product next to the chair. The year is 2026. The fork is a shampoo bottle.

The same bottle, from the same distributor, can end the year in three different places on her Schedule C — because the form does not ask what she bought. It asks what happened to it. A bottle she opens and uses up on clients goes one way. A bottle she sells to a client goes another. And a bottle in the hands of a renter whose product sales barely exist can skip the machinery entirely, under a sentence Publication 334 prints for service businesses. This article reads all three prongs and picks no winner. What moves a bottle from one line to another is a fact about her year, not a preference.

§2Where the product money lands first

Everything she takes in lands in one place. The Instructions for Schedule C put gross receipts or sales on line 1 — all client service income, retail product sales, and a self-employed person's tips together. A $40 bottle sold across the counter is line 1 money exactly like a $40 service. Nothing about the fork changes line 1.

The fork is entirely on the cost side. Her product purchases leave the return through two different doors, and the door is chosen by the bottle's destination:

• Consumed in the service — product she uses on clients, the back-bar shelf.
• Held for resale — product she stocks to sell, the retail shelf.

A third posture sits next to both: product sales so incidental to the service business that the resale machinery is never switched on. Each door has its own section of the form, and its own test. Read them in order.

§3The Fork: one bottle, three doors

Door one — the back bar, line 22. The Instructions for Schedule C treat supplies on line 22, and the test printed there is consumption: supplies are deducted on line 22 only to the extent actually consumed or used during the year. A bottle opened in March and emptied on clients by November is line 22 cost. The same bottle still three-quarters full on December 31 is mostly not — the unconsumed remainder waits for the year it is used. One softening sentence the instructions also print: for incidental supplies where no inventory or records are kept, the cost of what was purchased may be deducted if the method clearly reflects income. That sentence is about small incidental supplies, not about a stocked shelf.

Door two — the retail shelf, Part III. Product held for resale does not take the supplies door at all. Publication 334 figures cost of goods sold in Part III of Schedule C, lines 35 through 42, and the result — line 42 — is carried to line 4, where it reduces gross receipts before gross profit is figured. Part III is inventory arithmetic: Publication 334 values inventory at the beginning of the year and at the end of the year, adds what was purchased in between, and the bottles still sitting on the shelf at year-end come back out. A bottle in Part III is not deducted when it is bought. It is deducted, through line 42 and line 4, in the year it is sold — and only the cost of the bottles actually sold.

Door three — no COGS at all. Publication 334, in the same chapter, prints an exit: cost of goods sold is not required to be figured if the sale of merchandise is not an income-producing factor for the business — and the publication frames that as the posture of most service businesses. A renter who sells a handful of bottles a year as a courtesy, where the money that matters is the chair work, is who that sentence describes. The exit does not move a sale off line 1 — retail product sales are gross receipts whether or not COGS is figured. It switches off the Part III machinery on the cost side. Note what decides between door two and door three: not the bottle, and not the amount spent on it, but whether selling merchandise is genuinely one of the ways her business produces income.

§4Worked example: both shelves, one year, split correctly

One worked example, with numbers used only in this article. Our renter is in her first year renting a booth. These are hypothetical figures, not a prediction and not your numbers. She buys the same shampoo two ways: a retail stock she sells to clients, and a back-bar stock she uses on them.

Her year, on the product side. Retail stock: $450 of product sat on the shelf on January 1. She bought $3,600 more for resale during the year, and $700 of retail product was still on the shelf on December 31. Back-bar stock: she bought $1,150 of product to use on clients, used up $980 of it during the year, and $170 worth sat unconsumed at year-end. Her receipts for the year were $31,400 in services, $1,850 in tips, and $4,900 in retail product sales. She had no returns or allowances. Her booth rent — the figure read line by line in Stylist Article 1, on line 20b — was $650 a month, $7,800 for the year; it is carried here only so the walk can end at net profit, and no number from that article is reused.

Part III first. Beginning inventory $450, plus purchases of $3,600, is $4,050 of product available to sell. Subtract the $700 still on hand at year-end, and cost of goods sold is $3,350. That is the cost of the bottles that actually left in clients' bags. Line 42 carries $3,350 to line 4.

Line 22 takes the other shelf — and only the consumed part of it: $980. The $170 of back-bar product she bought but did not use is not a 2026 deduction under the consumption test printed on that line; it is next year's cost, when it is used.

Now the whole return, in the order the form builds it. Line 1 is $31,400 plus $1,850 plus $4,900 — $38,150. Line 4 takes the $3,350 from line 42, so gross profit on line 5 is $38,150 minus $3,350 — $34,800. No other income applies, so gross income on line 7 is $34,800. Part II, on the lines this example uses, is booth rent of $7,800 on line 20b and back-bar supplies of $980 on line 22 — $8,780 on line 28. Line 31, net profit, is $34,800 minus $8,780: $26,020.

Check the split against the cash. She spent $4,750 on product during the year — $3,600 retail, $1,150 back-bar. The return deducted $4,330 of product cost: $3,350 through Part III and $980 through line 22. The $420 difference is not an error. It is the growth in what she holds: she started the year with $450 of product on hand and ended it with $870 — $700 of retail stock plus $170 of unconsumed back-bar product. Inventory growth is exactly what Part III's beginning-and-ending arithmetic, and line 22's consumption test, exist to hold back from the current year's deduction.

Had she pushed every product purchase through line 22 and skipped Part III, the year's deduction would have been the full $4,750 and line 31 would have read $420 lower. This article does not call that figure wrong as a strategy — it is not presented as one. It reads differently because it treats bottles still on the shelf as if they had been used up, and for product held for resale, Part III is where the form puts them.

§5What this form does not cover

Part III does not decide whether your product selling is a real income-producing activity — the fact that routes you between door two and door three is a fact about your business, and Publication 334 prints the exit without scoring anyone's shelf. The form also does not cover sales tax on the bottles you sell: that is a state matter, and state taxes are not covered on this site. And nothing in this fork classifies the renter herself — whether a stylist is a booth renter filing Schedule C at all, rather than a salon employee, is a separate question this article assumes is already settled.

Software numbers vs ask-a-human numbers. The figures software can carry: line 1's total, the Part III beginning-plus-purchases-minus-ending arithmetic, line 42's carry to line 4, and the consumed amount on line 22 from whatever usage records exist. Numbers to take to a human before you act on them: whether your product sales have grown past "not an income-producing factor" into a retail stream that belongs in Part III, and how to value the inventory on your shelf at year-end if you have never counted it before.

That is the fork, as written: a bottle used up on clients is a line 22 supply, to the extent it was consumed; a bottle sold to a client runs through Part III, lines 35 to 42, and reaches the return at line 4; and a renter whose merchandise sales are not an income-producing factor is excused by Publication 334 from figuring cost of goods sold at all. Three doors, one bottle — and the destination, not the purchase, decides.
