Choosing Your Business Structure:

A plain-English breakdown of Sole Proprietorship vs. LLC vs. Corporation for writers on both sides of the border

​

When you start making regular money from your books, the question of legal business structures always comes up. It sounds dry, intimidating, and full of legalese — but it's really just about matching your current career stage to the right legal setup.

 

Here is a plain-English breakdown of the most common paths for writers in the US and Canada, stripped of all the confusing jargon.

​

1. The Sole Proprietorship (US & Canada)

​

The Vibe: The "Do Nothing" Option

​

How it works: If you have published a book, started making sales, and haven't filled out any government business forms — congratulations, you are already a Sole Proprietor. In the eyes of the IRS (US) and the CRA (Canada), you and your writing business are the exact same legal and financial entity.

​

The Pros: 100% free. Zero setup paperwork. You are in business the moment you make your first sale.

​

The Cons: Zero liability protection. Because you and your business are the same entity, if someone sues you over a copyright dispute or an accidental defamation issue, your personal assets — your house, your savings, your car — are technically on the line.

​

The Tax Situation: Simple. All profit flows directly onto your personal tax return (Schedule C in the US / Form T2125 in Canada), and you pay normal income tax plus self-employment taxes on every dollar you earn.

​

 

Canadian authors: Once your income from self-employment crosses $30,000 CAD in any 12-month period, you are legally required to register for GST/HST. This catches a lot of indie authors off guard — mark that threshold and plan for it early.

​

When to choose it: You are a Debut Author or hobbyist testing the waters — figuring out whether writing is going to generate real, consistent income.

​

2. The Limited Liability Company - LLC

(US Only)

​

The Vibe: The "Corporate Shield"

​

How it works: An LLC is a formal legal structure you register with your state. Its primary job is to create a legal wall between your personal life and your publishing business.

 

Canadian authors: Canada does not have a direct equivalent to the LLC. Your next step up from Sole Proprietor is full Incorporation — skip ahead to Section 3.

​

The Pros: Peace of mind. If your publishing business gets sued, only the assets owned by the LLC — like your book royalties or business bank account — are at risk. Your personal home and savings are protected behind the wall. It also signals professionalism when you are signing contracts with publishers or agents.

​

The Cons: It costs money to set up and maintain. Depending on your state, you will pay a filing fee plus an annual renewal fee.

​

The Tax Situation: By default, the IRS taxes a single-member LLC exactly the same way as a sole proprietorship. An LLC does not automatically save you money on taxes — it is purely a legal shield. Tax savings come at the next stage.

​

When to choose it: You are a Growing Author with multiple titles out. You are investing in editors, running ads, and signing contracts. The moment you have personal assets worth protecting, it is time for an LLC.

​

3. The Corporation

(US S-Corp / Canadian Incorporated Co.)

​​​

The Vibe: The "Tax Saver" — For High Earners

​

How it works:

• In the US: An S-Corp is not a new business type — it is a special tax election your LLC files with the IRS. You are telling the government you want to be taxed differently.

​

• In Canada: You formally incorporate federally or provincially, creating a completely separate legal "person" — a Corporation — that is distinct from you as an individual.

​

The Pros: Significant tax savings. Instead of paying self-employment taxes on all your net profit, you split your income. You pay yourself a reasonable salary (taxed normally), and the remaining business profit is either taken as a distribution or left inside the corporation.

​

• US authors: The self-employment tax savings on that distributed income can be substantial once you are earning consistently.

​

• Canadian authors: Incorporation gives you access to the Small Business Deduction (SBD), which taxes your first ~$500,000 of active business income at roughly 9–13% federally (plus provincial rates) — compared to personal income tax rates that can exceed 50% at higher income levels. That is the Canadian equivalent of the S-Corp advantage.

​

The Cons: High administrative overhead. You are legally required to run an official payroll system for yourself, file a separate corporate tax return, and keep meticulous business records. A bookkeeper and a specialized accountant are no longer optional — they are a cost of doing business.

​

When to choose it: You are a Seasoned Author with consistent, high income. As a general rule of thumb:

​

• US authors: It typically makes financial sense once your net author profit consistently clears $60,000–$80,000 USD per year.

​

• Canadian authors: The SBD savings tend to outweigh the overhead costs once you are netting roughly $50,000–$60,000 CAD per year.

​

Below those thresholds, the cost of payroll software and professional accountants will eat up most of the tax savings.

Summary Table: Quick Reference

​

1. SOLE PROPRIETOR

• Setup Cost: $0 (Free)

• Liability Protection: ❌ None (Hobbyist level)

• Best For: Brand new authors testing the waters.

 

2. LIMITED LIABILITY COMPANY (LLC) (US only)

• Setup Cost: Low to Moderate (State specific)

• Liability Protection: Solid Personal Shield

• Best For: Authors with a growing backlist and real assets.

​

3. CORPORATION

• Setup Cost: High (Admin/Payroll)

• Liability Protection: Solid Personal Shield

• Best For: High-earning authors netting over $60k–$80k+ USD or $50-60k CAD

​

​Canadian authors — your path is straightforward: Sole Proprietor → Corporation. There is no LLC step. When the time is right, you incorporate provincially (cheaper) or federally.

​

JO AND JODI REMINDER: An LLC or Corporation only protects you if you actually treat it like a separate entity. The moment you use your business account to pay for personal groceries — or your personal account to cover a business expense — you risk "piercing the corporate veil." A court can throw your asset protection out the window entirely. Keep those finances completely separate. Always.
