Hiring your first employee changes how your business deals with the Canada Revenue Agency, or CRA. Before you can deduct and remit income tax, Canada Pension Plan contributions, and Employment Insurance premiums, you’ll generally need the correct business and payroll accounts in place.
For a new employer, the terminology can make this process seem more complicated than it is. A business number Canada registration identifies your business, while a payroll program account connects your payroll reporting and remittances to that number.
This guide explains how the accounts fit together, what information to prepare, and what responsibilities begin once registration is complete.
How to Register for a Business Number and Payroll Program Account in Canada
The process usually involves confirming whether your business already has a business number, obtaining one if it does not, and adding a payroll deductions account. Businesses can often complete both registrations during the same online session.
Registering the accounts is only the setup stage. Once you begin paying employees, you remain responsible for calculating deductions, sending remittances, maintaining records, and completing the required payroll reporting.
1. Determine If You Need a Business Number and Payroll Account
A business number, commonly called a BN, is the unique nine-digit identifier the CRA uses for a business or legal entity. Program accounts for payroll, GST/HST, corporation income tax, and certain other activities are attached to that number.
Not every unincorporated business needs a BN immediately. You generally need one when you incorporate or register for a CRA program account, including payroll deductions. A business should have only one BN for the same legal entity.
A payroll account may be required when you pay salaries, wages, bonuses, vacation pay, tips, taxable benefits, or certain other employment-related amounts. If you’re still working alone and have no employees or applicable payments, you may not need to open one yet.
Worker classification also matters. When you’re uncertain whether someone is an employee or self-employed, the answer should be clarified rather than assumed, since it affects your deduction and reporting obligations.
2. Gather Required Business Information
Preparing your information before opening the registration portal can prevent interruptions and inconsistent entries. The exact details depend on the business structure and program accounts requested, but you should expect to provide information such as:
- the business’s legal and operating names;
- its physical and mailing addresses;
- its structure, ownership, and primary business activity;
- contact information for an authorized person; and
- identification details needed to confirm authority over the business.
You’ll also need payroll-related information, including the date employees are expected to receive their first pay and an estimate of payroll amounts where requested.
Use the registered legal name rather than an informal variation. Check addresses, dates, and identification numbers before submitting them, especially when another person helped incorporate or register the business.
Your company may already have a BN if it was incorporated federally or provincially, registered through certain provincial processes, or previously registered with the CRA. Check business records and CRA correspondence before creating another registration.
3. Register for a CRA Business Number
Business Registration Online, or BRO, is the CRA’s standard online service for obtaining a BN and opening common program accounts. Since July 14, 2026, BRO has been accessed through a CRA account using CRA credentials, a Sign-In Partner, or an eligible provincial partner.
A Canadian resident business can sign in, add a business account, and select the option to register a business. If it does not already have a BN, the number can be assigned as part of the program-account registration.
Businesses unable to complete the online process may use Form RC1, Request for a Business Number and Certain Program Accounts, and mail it to the appropriate tax centre. Non-resident businesses follow a separate registration process.
Keep the confirmation information after registration. Your BN will remain the core identifier used when other CRA program accounts are added.
4. Add a Payroll Program Account to Your Business Number
A CRA payroll deductions account contains 15 characters: the nine-digit BN, the two-letter payroll identifier “RP,” and a four-digit reference number. A typical first payroll account ends in RP0001.
If the business already has a BN, you add the payroll program account to that number rather than registering for a new BN. If it needs both, BRO generally allows them to be set up during the same registration process.
Linking payroll to the correct legal entity is essential. Using another company’s BN or opening duplicate accounts can complicate remittances, records, and year-end reporting.
The CRA states that employers must register before their first remittance due date. For many new employers, that due date is the 15th day of the month after deductions first begin, unless the CRA assigns another remittance frequency.
5. Understand Payroll Responsibilities and CRA Requirements
Opening a payroll account does not complete your employer obligations. For each employee, you may need to obtain a Social Insurance Number, determine the province of employment, and collect the applicable federal and provincial or territorial TD1 forms.
You’ll then calculate the required CRA source deductions. These commonly include income tax withholding, CPP contributions, and EI premiums. The employer must also account for its own applicable CPP and EI portions.
Amounts withheld must be remitted according to the schedule assigned by the CRA. Payroll records must support the figures reported, and year-end responsibilities may include preparing and filing T4 slips and summaries.
This is where payroll can become stressful for a first-time employer. Ayali Pay’s client guidance emphasizes simple explanations, direct support, and fully managed payroll that covers deductions, direct deposits, Records of Employment, and T4 or T4A reporting.
6. Keep Records and Stay Compliant
Maintain organized records for employee information, hours, wages, taxable benefits, deductions, remittances, pay statements, and year-end documents. Records should be updated during each pay period rather than reconstructed months later.
Create a payroll calendar that tracks pay dates, remittance deadlines, and year-end reporting. Even when software performs calculations, the employer remains responsible for providing accurate information and meeting its obligations.
A managed service can take on much of the processing and administrative work. Ayali Pay positions its fully managed service as a personal payroll department for employers who want end-to-end support and access to dedicated specialists rather than a call-centre experience.
Common Mistakes When Registering a Business Number Canada and Payroll Account
A common error is requesting another BN when the business already has one. Others include choosing the wrong program account, using inconsistent legal information, entering an incorrect first-pay date, or waiting until after a remittance deadline to register.
New employers may also confuse the nine-digit BN with the full payroll account number. Confirm that the account includes the RP identifier and correct reference number before using it for remittances or correspondence.
Review all details before submitting the registration. A few careful minutes at setup are far more pleasant than untangling duplicate accounts later, a small administrative beast best left sleeping.
