No. You can publish, sell and be paid as an individual — in most countries that makes
you a sole trader or sole proprietor automatically, with no registration required. You do
have to declare the income and pay tax on it. Forming a company becomes worth considering
once the income is substantial and steady, mainly for liability protection and tax
treatment, not because publishing requires it.
The longer version
Publishing platforms do not ask whether you have a business. KDP, IngramSpark,
Draft2Digital and the rest ask for a name, an address, a bank account and a tax identifier.
An individual satisfies all four.
What is not optional is the tax side. Royalty income is income everywhere, and platforms
report it. In most jurisdictions selling books puts you in business by default, whether or
not you register anything.
What you have to do regardless
- Complete the platform tax interview. KDP requires one before it will pay you. It asks
for a tax identification number and your country of residence
- Declare the income on your tax return
- Keep records — royalty statements, production costs, marketing spend, equipment. These
are usually deductible against the income, which is the main reason to keep them
- Handle cross-border withholding. US platforms withhold tax on payments to non-US
authors unless a treaty rate applies and you have supplied the right identifier. Getting
this right early is worth real money
When a company starts to make sense
There is no universal threshold. The triggers most authors hit are:
- Liability. A company separates business risk from personal assets. For most fiction
authors the practical risk is low; for non-fiction making factual claims, or for authors
hiring contractors, it is less theoretical
- Tax efficiency. Above a certain income, the way a company is taxed can beat personal
rates. Below it, a company usually costs more in accounting fees than it saves
- Separating identities. An imprint or company can hold ISBNs, which keeps a legal name
out of public ISBN records — relevant if you run a firewalled pen name
- Working with others. Co-authors, an assistant, or a small team
The honest general answer: if publishing income is a side income, an individual is almost
always simpler and cheaper. When it becomes a primary income, get advice from an accountant
in your country — this is exactly the point where generic online guidance stops being
useful.
An imprint is not a company
Worth separating, because they get conflated. An imprint is a publishing name that
appears on the book and in ISBN records. In most places you can invent one without
registering anything. A company is a legal entity.
You can have an imprint without a company. Many authors do.
Common exceptions
- Rules vary enormously by country. Some jurisdictions require registering a trading
name, or registering for VAT/GST above a turnover threshold.
- Selling direct from your own website can trigger sales tax, VAT and consumer-law
obligations that selling through retailers does not.
- US authors may find an EIN useful even as a sole proprietor, because it can be given
to platforms instead of a Social Security Number.
- If you already have a day job, check your employment contract for clauses about
outside income or intellectual property.
