Part of A realistic take on miniature building, 2027 edition
Where independent miniature makers draw the hobby line
Independent miniature makers explain where they stop treating painting and sculpting as a hobby and start running it as a real small business.
What to take away
- Independent miniature makers draw the hobby line at conduct, not income: the IRS weighs books, records and intent to profit, and profit in three of five years is the stated presumption in Publication 535.
- In the United States, a seller applies for an EIN on Form SS-4, registers for state sales tax, and reports the activity on Schedule C.
- Copyright covers the sculpted scene, not the joinery, the hinge or the bookshelf-insert idea.
- Batch runs tie up cash in stock; commissions pay first and can eat a month.
- Photograph each finished piece, keep the cut list and paint mix with it, and file receipts by project.
- Canadian makers are the second market in this article: price landed cost with CBSA duty and GST/HST before setting a sale price.
Independent miniature makers and the line each drew
These working independents show the decision in public output, not interviews. Each names the point where the craft stopped being only a hobby.
The detail below comes from what each maker sells and publishes. None of them discloses income, so read every split as a description of their public output, not a figure they gave.
Chris Toledo builds 1:12 period interiors in Los Angeles and posts the failures alongside the finished rooms. He treats teaching as the business and commissions as the exception. His public classes and build videos put the income on instruction, not on one-off sales.
Julie Warren publishes 1:12 room boxes and kits from Ireland. Her line sits at kits: the design labor stays with her, the assembly labor moves to the buyer. A kit buyer gets plans and parts; Warren keeps the design work and the repeat sale.
Debbie Young works in 1:24 and 1:48 out of the United Kingdom, selling finished pieces and tutorials. Small scale is the business model, because a 1:48 room fits a shelf and a shipping box. Her line is finished work plus teaching, not full-size room commissions.
Sue Heaser comes from polymer clay and jewelry, and her line is materials: she sells techniques and books, not finished rooms. That keeps her output in instruction and supplies, which ship in envelopes.
The Mini Time Machine Museum of Miniatures in Tucson is the institutional end of the same line, commissioning and holding work rather than selling it. It shows where a maker can aim when the work leaves the retail table.
Where Publication 535 draws the hobby line
Selling one room box does not make anyone a business, and giving work away does not keep anyone out of being one. The IRS treats this as a question about conduct, and Publication 535 sets out the factors in its chapter on activities not engaged in for profit.
The page on the difference between a hobby and a business lists the deciding questions. Was the activity carried on in a businesslike way, with complete and accurate books? Does the maker change methods to improve profitability? Has it produced a profit in some years?
Treasury Regulation 1.183-2(b) names nine of those factors, including the time and effort put in, the expertise of the maker, and the elements of personal pleasure in the work.
Section 183(d) adds a presumption: profit in three of five consecutive years counts as evidence that the activity is run for profit. Miss three of five and the burden stays where it started.
Two of those items, records and businesslike conduct, are things you either did from the start or cannot retrofit. Read the list before the first sale.
Below the line, the IRS calls the activity a hobby. The income still gets reported, as other income on Schedule 1 of Form 1040, and it carries no self-employment tax. Hobby expenses are generally not deductible for most individual filers right now, so the materials are paid with money that has already been taxed.
Above the line, the same sales go on Schedule C, and net earnings of $400 or more bring Schedule SE and self-employment tax.
What the law protects, and what it does not
Miniature makers copy each other constantly, some of it fine and some of it not. Title 17 of the United States Code defines pictorial, graphic and sculptural works to include three-dimensional works of applied art, and names models.
The protection runs to form, not function. A useful article counts only where its artistic features can be identified separately from, and exist independently of, the utilitarian aspects.
Read plainly: the sculpted scene is protected. The joinery method, the hinge, the way a drawer slides and the general idea of a bookshelf insert are not.
What a maker can do is concrete: put the license in writing, state what the buyer may do with the file, watermark the pattern sheets, and register the work with the US Copyright Office.
Batching against commissions
Solo makers usually settle into a mix, because the two modes fail differently.
Maker income modes compared
Batch run
- Cash timing
- Money out first
- Main risk
- Dead stock
- Labor
- Maker builds all
Commission
- Cash timing
- Paid before build
- Main risk
- Difficult client
- Labor
- Maker builds all
Kits
- Cash timing
- Paid at order
- Main risk
- Assembly problems
- Labor
- Assembly to buyer
Cash timing
- Batch run
- Money out first, back on sale
- Commission
- Paid before the build
- Kits
- Paid at order
- Tutorial or book
- Paid at sale or subscription
Main risk
- Batch run
- Dead stock in a slow month
- Commission
- One difficult client eats a month
- Kits
- Buyer assembly problems land on you
- Tutorial or book
- Piracy and stale material
Kits sit between the two, moving the assembly labor to the buyer and the design labor to the maker. Most people discover their answer by cost rather than preference, which is why pricing supplies tends to be the first spreadsheet anyone builds.
A worked example of the line, in numbers
Take a maker who sells one finished 1:12 room box a month at a price covering materials plus hours. Nothing about that is a business.
The numbers behind one such box are worth writing down. Materials run about $180: sheet wood, strip wood, a lighting kit, paint and glue. The build takes 14 hours, and at a self-set $25 an hour that is $350.
Tooling wear and one failed build in three add about $40. Total cost lands near $570, so a sale at $690 returns the $350 of labor plus $120, near $33 an hour for the 14 hours at the bench.
Twelve boxes a year at that price is $8,280 in sales against $6,840 of materials, hours and tooling. That is a thin margin, and it is why the line is about conduct rather than the total.
Now suppose the same maker photographs every build, keeps the cut list and paint mix with the photo, and files receipts by project. The conduct changed before the income did.
That is the line the IRS describes. It is crossed at the bench, months before it shows up in a tax return.
Records that make next year's Schedule C easier
The habits that separate a working practice from a pile of finished objects are unglamorous. Photograph each piece finished and lit, in the same place each time. Keep the cut list and the paint mix with the photograph. Note hours honestly, including the evening spent redoing a wall. File receipts by project rather than by month.
Filed that way, the receipts answer the Schedule C lines for materials, supplies and contract labor without a year-end sort.
None of that is needed to enjoy the work, and all of it is needed to answer whether a piece was worth building. Anyone still learning the craft should start with building at this scale and time the first three builds, because those hours set every later quote.
Common questions
Do I need to register a business to sell a few pieces?
In the United States, the trigger is sales tax, not the IRS. Apply for an employer identification number on Form SS-4, then register with your state department of revenue. States set their own economic nexus threshold, so the figure that obliges you to collect differs by state.
Canada is the second market here: register for GST/HST with the CRA, and ask CBSA about duty on imported stock before the first sale.
The CRA small supplier threshold for most makers is $30,000 in taxable revenue over four consecutive calendar quarters. Local licensing is set by your state, province or city, not by this article.
Can someone copy my design?
The artistic form is protected. The construction method and the general concept are not, so expect the format to spread even when the scene does not.
How do makers price a one-off?
Materials plus hours plus a share of tooling and failures. The failures line is what beginners omit, and it is usually the difference between a price that works and one that does not.
