Business & Tax Basics

This is general orientation for self-publishing in the US, not legal or tax advice. Rules vary by state, and a local accountant can answer your specific situation in one short call.

Do you need an LLC to self-publish?

No. In the US you can self-publish as an individual, under your own name or a pen name, without forming any business entity. KDP and most other retailers just ask for your tax information (a Social Security number or an EIN) when you set up the account. Without forming anything, you're treated as a sole proprietor, and your book earnings count as self-employment income.

What you don't need an LLC for

• Opening a KDP or Draft2Digital account.
• Buying your own ISBN. Individuals can buy them directly through Bowker.
• Owning your copyright. You own it automatically as the author; registering it with the Copyright Office is optional.
• Publishing under a pen name. The pen name goes on the cover and the listing, while your legal name stays on the account's tax information.

Why some authors form one anyway

• Some personal liability protection. It has limits, and it only holds up if you keep business and personal money separate.
• A business address on your copyright page and listings instead of your home address.
• A cleaner way to separate book income and expenses, though a separate bank account does most of that job without an LLC.
• Publishing under an imprint name. You can use an imprint name without an LLC, but some states want an assumed-name (DBA) registration for it.
• Tax planning later. Once a book earns real money, an accountant may suggest a different structure for tax reasons.

What it costs

State filing fees run from tens of dollars to a few hundred, and some states also charge annual fees, which can be much larger (California's minimum is $800 a year, for example). A registered agent service, if you use one, costs extra. Check your own state's Secretary of State website for current fees before deciding.

Taxes: track this from day one, with or without an LLC

• Book earnings are self-employment income. Once your net earnings pass a small threshold, you generally owe self-employment tax on top of regular income tax.
• Business expenses like editing, cover design, ISBNs, ads, and software may be deductible against your book income. Keep every receipt.
• If you expect to owe a meaningful amount, you may need to pay estimated taxes quarterly instead of one lump sum at filing time.
• Use a separate bank account or card for book income and expenses. It isn't legally required, but it makes everything else easier.
• Major retailers like Amazon collect and remit sales tax on their own sales. If you sell directly (your own site, conventions), state sales-tax rules apply and vary.

Where to get real help

A local CPA or enrolled agent is the right person for tax questions. Your state's Small Business Development Center (SBDC) offers free or low-cost advising for new businesses. For anything about liability or contracts, a short consult with an attorney is worth it before you sign something.
