Can I convert my sole proprietorship into a corporation later?

TSL Written by the Treadstone Law team· Updated June 2026

Yes. You can incorporate at any point and transfer your sole proprietorship business into the new corporation. This is a common path — many businesses start as sole proprietorships and later incorporate once the benefits outweigh the costs.

The transfer process involves more than just registering a company. You need to decide which assets and contracts move into the corporation, update contracts with clients and suppliers, open new business bank accounts, and re-register for HST in the corporation's name. Any leases or significant agreements may need the landlord or counterparty's consent to assign.

From a tax perspective, transferring assets — such as equipment, inventory, or goodwill — can trigger a disposition at fair market value, which may create a taxable gain. A section 85 rollover under the Income Tax Act (federal) allows you to transfer eligible property into the corporation on a tax-deferred basis by electing a specific transfer price. This is a common tool but requires careful planning and must be done correctly to be effective. Working with an accountant and lawyer together is strongly recommended.

Key takeaways

  • Converting a sole prop to a corporation is possible at any stage.
  • Contracts, bank accounts, and HST registration need to be updated.
  • Transferring assets can trigger a taxable disposition — a section 85 rollover can defer the tax.
  • Professional coordination between a lawyer and accountant is important for a clean transition.
