Sole Proprietorship to Corporation in Canada: BN, GST/HST, Bank

A corporation is a new taxpayer with its own business number; the GST/HST and payroll accounts on your old number do not move to it. Pick a transfer date, incorporate, open its tax and bank accounts, move assets at market value or by section 85 election, switch clients and platforms, then close the old accounts and file a final T2125.

Sole proprietorship to corporation in Canada: what changes, and in what order?

Everything that carries your name or your business number (BN) has to be moved or replaced, because the corporation is a different legal person. The CRA treats incorporating an existing business as a change of legal status: the corporation gets a new BN, the GST/HST (RT) and payroll (RP) accounts on your old BN do not move to it, and you close the old BN and its accounts (CRA: Change of legal status).

StepWhat to doWhen
1Pick the transfer date; incorporate (How to incorporate in Canada)First
2Get the corporation's new BNAfter incorporating
3Register its GST/HST (RT) account, if neededBefore the transfer date
4Open its bank account; move processors and platformsBefore the transfer date
5Move assets, with any section 85 and GST44 elections (Moving a business into a corporation)On the transfer date
6Tell clients and suppliers; invoice in the corporation's nameFrom the transfer date
7Open its payroll (RP) account; final remittance on the old oneBefore its first remittance is due
8Move licences, insurance, leases, loans and the business nameBefore the transfer date
9Close the old accounts; file the final T2125Payroll: remit and file slips, then close. GST/HST: close, then file the final return. BN last

A case is not simple when assets worth real money move (an election sets their tax value, and a late one brings a penalty or can be refused), when you have staff, or when you are registered for GST/HST (the corporation must be registered too for the GST44 election). The order matters: the corporation's accounts must exist before customer money, invoices and payroll start running through it.

Gather first: the transfer date, a list of assets with cost and market value, every account, platform, loan, lease, licence and contract in your name, and your BN, RT and RP numbers with the last returns filed.

Step 1: Which date does the corporation take over?

The transfer date is the day the corporation starts running the business; everything before it is yours, everything from it is the corporation's. Put it in a written transfer agreement that lists what moves. Pick a date the bank account and CRA accounts can be ready for, often the first day of a month. Which sales and bills fall on each side of the date is covered in Books after incorporating a sole proprietorship.

Step 2: Does the corporation keep my business number?

No. The corporation gets a new BN with a corporation income tax (RC) account. Incorporating federally, or in Alberta, British Columbia, Manitoba, New Brunswick, Nova Scotia, Ontario, Prince Edward Island or Saskatchewan, registers the new BN automatically (CRA: When you need a BN); otherwise, register it with the CRA once you have the incorporation documents. Then register RT and RP accounts on the new BN if the corporation needs them (CRA: Change of legal status). A business physically located in Québec registers and files GST/HST with Revenu Québec instead (CRA: Register as a resident). Fixing an account set up wrong is covered in After you incorporate.

Step 3: Does the corporation need its own GST/HST number?

Yes, if it is not a small supplier or chooses to register. The $30,000 test counts the taxable sales of the corporation and its associates (CRA: When to register; Excise Tax Act, section 148), and a person who controls a corporation is its associate (subsection 127(2)). Association is tested at the start of each calendar quarter, so from the corporation's first full quarter your sales in the four quarters before it count toward its total.

If you are registered for GST/HST, the election that moves the business without GST/HST (step 5) needs the corporation registered too: it is not available when the seller is registered and the buyer is not (Excise Tax Act, paragraph 167(1)(b)). So register the corporation before the transfer date. The registration test is in When to register for GST/HST.

A provincial sales tax number in your name does not move either. British Columbia must be told when a sole proprietor becomes a corporation, and a PST number is not transferable (BC: PST Bulletin 001); elsewhere, ask the province or Revenu Québec whether the corporation needs its own PST, RST or QST number. See Charging GST/HST, PST and QST by province.

Step 4: Do my bank account and payment platforms move to the corporation?

No. Open a bank account in the corporation's name and move card processors, payment links and online platforms to the corporation's name and BN before the transfer date. Once the corporation has taken over the business, its sales are generally its income wherever the money lands, so a deposit to your own account has to be traced back into its books and GST/HST return. Platforms report sellers to the CRA by name and tax number: a SIN for an individual, a business registration number for an entity (CRA: Information platforms share). An account left in your name reports the corporation's sales under you. To fix money already mixed, see Corporate income in a personal account.

Step 5: Transferring assets from a sole proprietorship to a corporation: which ones, at what value?

Each item that moves is a sale by you to the corporation, so list every one in the written transfer agreement. Because you control the corporation, you do not deal with it at arm's length (Income Tax Act, section 251), so a transfer below market value is treated as a sale at market value for you (section 69). Moving a vehicle "for nothing" does not avoid the tax, and if you owe tax for that year or earlier, the corporation becomes liable for it too, up to the value it did not pay for (section 160).

The alternative is a section 85 election: you take back consideration that includes shares, and you and the corporation jointly elect an agreed amount for each eligible asset, which becomes your proceeds and the corporation's cost (Income Tax Act, subsection 85(1)). The election goes on Form T2057, due by the earliest income tax return filing deadline of either party for the transfer year (subsection 85(6)). For Québec income tax, you and the corporation also file Form TP-518-V with Revenu Québec by the later of the earliest relevant income tax return filing deadline and the last day of the second month after the later party's tax year-end; filing late brings a penalty.

ItemGather
Vehicles and equipmentCost, remaining tax cost, market value, ownership papers
InventoryCount and cost at the transfer date
Unpaid customer invoicesList at the transfer date, with amounts already reported as income
Goodwill and client listsWhat the business is worth beyond its assets

The agreed-amount limits, late filing and receivables are in Moving a business into a corporation.

GST/HST is a separate question. When the corporation acquires all or substantially all (generally 90% or more) of the property needed to run the business (CRA: Memorandum 14-4), you and the corporation can jointly elect on Form GST44 so that no GST/HST is payable on most of the transfer. A registered corporation files it by the due date of its first GST/HST return covering tax that would otherwise arise on the transfer. Services you will still supply, leases and licences stay taxable (Excise Tax Act, subsection 167(1.1)). Isolated assets moved without the rest of the business do not qualify. In Québec, the election is filed with Revenu Québec on its own form, named in Moving a business into a corporation.

Step 6: Contracts, invoices and clients: what changes after the date?

From the transfer date, invoices and contracts go out in the corporation's name and, if it is registered, with its own GST/HST number; a federal corporation must use its legal name in contracts and invoices (Corporations Canada: Naming a corporation). A customer claiming an input tax credit on a purchase of $100 or more needs the supplier's registration number on the invoice (CRA: ITC information requirements). Never put your old RT number on the corporation's invoices; to correct invoices already sent, see After you incorporate.

Contracts signed in your name stay yours until the client signs a new one or agrees to an assignment, so read each contract's terms. Send clients and suppliers the corporation's legal name, BN, address and payment details, with the date they start dealing with it, and keep a copy. Clients that file a T4A or T5018 identify a business recipient by its business number (CRA: Filling out the T4A slip), so give them the corporation's details and ask that slips for its income name the corporation, not you.

Step 7: Do my employees need a new payroll account?

Yes. The corporation, as the new employer, needs its own RP account, registered before its first remittance is due: generally the 15th day of the month after the first pay with deductions (CRA: Payroll account). The old account must make a final remittance within 7 calendar days of the legal status change (CRA: When to remit). Before it closes, remit all source deductions, file the final information returns and give employees their slips, due 30 days after the old business stops unless the old balance moves to the corporation's account (CRA: When to file; CRA: Closing your accounts). Whether the old balance moves to the corporation, and the successor-employer rules for CPP and EI, are in Books after incorporating a sole proprietorship.

Step 8: Do licences, insurance, leases and my business name move automatically?

No. Each is held in a named holder's name under its own terms. Check each one with its issuer or the other party:

  • Business name: a name you registered personally is registered to you. A federal corporation operating under a name other than its legal name registers that name in each province or territory where it operates (Corporations Canada); a provincial corporation follows its province's rules.
  • Licences, permits and workers' compensation accounts: ask each issuer whether the corporation needs its own.
  • Insurance: have the corporation named as the insured before the transfer date.
  • Leases and loans: they move only if the landlord, lessor or lender agrees.
  • Vehicles: transfer the registration under your province's rules, along with the insurance and any loan.

Step 9: How do I close the sole proprietorship: final T2125 and old accounts?

Your business's fiscal period ends when it stops, so it can be shorter than 12 months (CRA: T4002, chapter 1). With the usual December 31 year-end, the final T2125 covers January 1 to the day before the transfer date and goes with your personal return for that year (CRA: Completing Form T2125). The corporation's own first tax year and first T2 are in First corporate tax year.

Close the old GST/HST account once the assets have moved: business property you still hold when the registration ends is treated as sold, with tax worked out on it (CRA: Close your GST/HST account). Closing comes first and creates up to two final periods, each with a return due one month after it ends; the second is needed only if there is tax to remit. The CRA's closing page does not deal with a business moving to a corporation, so confirm the cancellation date with the CRA; the detail is in Closing a GST/HST account. Then close the old BN; the CRA says some forms may be needed first (CRA: Closing your accounts). If another business or account of yours still runs under the old BN, ask the CRA which accounts to close. Amounts still owed on the old accounts stay yours. As the corporation's director, you can also be personally liable for GST/HST and payroll deductions it fails to remit; the CRA must act within 2 years after you last cease to be a director (Excise Tax Act, section 323; Income Tax Act, section 227.1).

What to keep on file for both sides

Keep the sole proprietorship's records for six years from the end of the tax year in which it ended (CRA: How long to keep your records). Both files hold a copy of the transfer agreement and the asset list.

Example

These examples are illustrative; all amounts are Canadian dollars.

An Ontario consultant's corporation takes over on July 1

She incorporates in June with a new BN, registers the corporation for HST from July 1 and opens its bank account. On July 1 she emails clients the corporation's name, BN and banking details; every invoice from then on shows the corporation and its own HST number. Her only asset, a laptop, moves at its market value (GST/HST on that sale is left out here). Her final T2125 covers January 1 to June 30. She then closes the old HST account, files its final return by the due date, and closes the old BN.

A contractor moves the business with four work vehicles

The whole business moves, including four work trucks worth $120,000 in total. Assume they are the whole capital cost allowance class, cost more than $120,000, and have a remaining tax cost of $70,000. Both sides are GST/HST registrants, so they sign GST44 and no GST/HST is charged on the transfer. Without an election, the $50,000 difference could be recaptured as income. A T2057 election with an agreed amount of $70,000, in exchange for shares, defers it if its conditions are met. The truck loans move only with the lender's consent, and a loan the corporation takes over counts as payment other than shares, which can raise the agreed amount.

An online seller leaves the processor in her name

Her corporation takes over the business on April 1, but she keeps her payment processor under her own name and SIN until June 30, and $45,000 of sales land there. Those are the corporation's sales: they go in its books and on its GST/HST return, and she owes the money to the corporation until she moves it across. The platform's report will still show the sales under her SIN, so she keeps the reconciliation.
