Should you incorporate your Amazon FBA business? When it pays and how to do it right

When incorporation starts paying for itself

The tax case for incorporating an FBA business rests on one behaviour: leaving profit in the company. An Ontario corporation pays about 12.2% combined tax on its first $500,000 of active income under the small business deduction, while the same dollar on a T2125 can face a personal marginal rate above 50%. Almost every growing FBA seller reinvests margin into inventory ahead of Q4 — that retained-profit pattern is exactly what incorporation rewards.

The liability case is just as real. You are the seller of record for every unit that ships, and Amazon requires sellers above roughly $10,000 USD in monthly sales to carry commercial general liability insurance. A corporation adds a legal wall between a product claim and your personal assets. Insurance still does the heavy lifting, but the wall changes what a plaintiff can reach.

If you spend everything the business makes, incorporation buys you little on tax. Canada's integration rules mean salary or dividends drawn out of the corporation land close to what a sole proprietor pays. Incorporate when retained profit, liability, or an eventual sale of the brand is on the table — not because a course seller told you to.

Federal or Ontario? What actually differs

For most FBA sellers, either works, and the differences are smaller than the internet suggests. Federal incorporation under the CBCA costs $200 online and protects your corporate name Canada-wide; Ontario incorporation under the OBCA costs $300 through the Ontario Business Registry. A named corporation needs a NUANS name search report under both regimes; a numbered company skips it and can register a trade name for the storefront brand instead.

One nuance for cross-border partnerships: since Ontario dropped its director residency rule, an OBCA corporation can suit a seller with a US co-founder. If your questions run deeper — treaty positions, US sales tax, state filings — start with our cross-border accounting page for Amazon sellers.

Moving your Amazon account into the corporation

Amazon's terms say seller accounts are not transferable, but you can update the legal entity on your own account — and that is exactly how an incorporation cutover works in practice.

• Update the business information in Seller Central to the corporation's legal name and address. Expect Amazon to re-run verification and ask for your articles of incorporation.
• Redo the tax interview. A Canadian corporation selling on Amazon.com completes a W-8BEN-E claiming Canada–US treaty benefits, replacing your personal W-8BEN.
• Switch the deposit method to the corporation's bank account, and update the GST/HST registration Amazon has on file to the corporation's new number.
• Pick a clean cutover date — a month-end outside Q4 — so settlements, bookkeeping, and GST/HST returns split cleanly between the old sole proprietorship and the new corporation.

Re-verification can take days or weeks. Do not start it the week before Prime Day or your holiday inventory send-in.

The CRA program accounts an FBA corporation needs

Your corporation is a new legal person with its own business number, and none of your sole-prop accounts carry over. A typical FBA seller opens four program accounts:

• RC — corporate income tax. The corporation files a T2 return every year, even a short or loss year.
• RT — GST/HST. Register from day one, whatever your revenue, so input tax credits on inventory, freight, prep services, and Amazon fees are never stranded.
• RM — import-export. Required to clear the inventory you import, alongside enrolment in CBSA's CARM Client Portal, which is now how importers are assessed duties and taxes.
• RP — payroll. Open it once you start paying yourself or staff a salary — before the first remittance deadline, not after.

NUANS, minute books, and the paper that protects the exit

A corporation is only as strong as its records. The minute book holds your articles, bylaws, share register, director and shareholder resolutions, and — for federal corporations — the register of individuals with significant control filed with Corporations Canada. Annual corporate returns keep the company in good standing; they are not tax returns, and missing them can lead to dissolution.

This matters to FBA sellers specifically because FBA brands get bought. Aggregators and brokers doing due diligence ask for the minute book, the share ledger, and proof the Amazon account, trademarks, and Brand Registry sit inside the corporation. Clean records also support the lifetime capital gains exemption on a future share sale. We build the corporate file once, properly, and keep it current alongside your ongoing compliance.
