Most authors, especially early on, operate as sole proprietors by default, without ever formally choosing that structure, and it's a completely legitimate way to run an author business, deduct expenses, and earn royalties; an LLC becomes more worth considering once income grows or liability concerns become real, not simply because you've published a book. Forming an LLC isn't required to write, publish, or earn money as an author, whatever the marketing from LLC-formation services might suggest.
This article provides general information, not legal, tax, or financial advice. Business structure decisions depend on your specific situation and state; consult an accountant or attorney before deciding.
This is part of the Complete Guide to Author Business Basics.
If you earn royalty or business income as an individual without forming a separate legal entity, you're automatically operating as a sole proprietor; there's no paperwork required to "become" one. You report business income and expenses on Schedule C of your personal tax return, and you and your business are legally the same entity, which matters for the liability discussion below.
A Limited Liability Company (LLC) is a separate legal entity you form through your state, which can offer:
A single-member LLC is still taxed like a sole proprietorship by default (income flows to your personal return via Schedule C), unless you elect a different tax treatment, so forming an LLC doesn't automatically change how you're taxed.
This structure tends to make sense when you're earning modest royalty income, and the LLC's costs would represent a meaningful chunk of your actual earnings, or when you're early in your author career and still establishing whether this will be an ongoing, income-generating business. It's also reasonable when you don't have significant liability concerns specific to your work, though highly controversial nonfiction, for instance, might warrant more caution than typical fiction.
Consider an LLC once your author income has grown to a level where the formation and ongoing costs are genuinely modest relative to earnings, or if you have specific liability concerns, such as writing about controversial real-world topics or people, where separating personal and business assets provides real peace of mind. It's also worth considering if you're running a broader author business beyond a single book, multiple titles, related services, coaching, or consulting, where a formal business entity makes practical sense, or if you simply want a more formal setup for banking, contracts, or working with a publishing team, independent of any tax or liability consideration.
A common misconception: you don't need an LLC to deduct business expenses. Sole proprietors can deduct legitimate business expenses (editing, cover design, marketing, a qualifying home office) on Schedule C without forming any separate entity. The LLC decision is about liability protection and business structure, not about your ability to claim deductions.
For many authors earning under a modest income threshold from writing, remaining a sole proprietor while tracking expenses carefully and paying estimated taxes is a completely reasonable, low-complexity approach. Revisit the decision as income grows or if specific liability concerns arise, rather than forming an LLC preemptively based on the assumption that publishing a book requires it.
Focus on Your Book; Consult a Professional on Structure
While Entrada doesn't provide legal or tax advice, we're glad to help authors think through the publishing side of their business.
No. You can publish, earn royalties, and deduct legitimate business expenses as a sole proprietor, without forming any separate legal entity.
Not automatically. A single-member LLC is taxed the same way as a sole proprietorship by default, unless you elect a different tax treatment, which adds complexity and generally isn't worthwhile until income justifies it.
Primarily, it can separate your personal assets from business liabilities in many circumstances, though this protection isn't absolute and depends on properly maintaining separation between personal and business finances.
Generally once your income has grown enough that the formation and ongoing costs are modest relative to earnings, or if you have specific liability concerns, rather than simply because you've published a book.
