What Is a CRA Payroll Account?

If your Canadian business is hiring employees, one of the first administrative steps you need to consider is registering for a CRA payroll account. This account allows the Canada Revenue Agency (CRA) to identify your business when you withhold and remit payroll deductions such as income tax, Canada Pension Plan (CPP) contributions, and Employment Insurance (EI) premiums. CRA describes the payroll deductions account as an account number assigned to an employer, trustee, or other payer of employment-related amounts.

A payroll account is commonly identified by the letters RP. It forms part of a 15-character account number consisting of your nine-digit Business Number (BN), the program identifier RP, and a four-digit reference number. For example, a business might have an account such as 12345 6789 RP 0001.

Having an RP account does not mean payroll compliance is finished. Once registered, the business must calculate deductions correctly, remit amounts to the CRA according to its assigned remitter schedule, maintain payroll records, and complete year-end information returns such as T4 slips when required.

Understanding the RP Account Number

The Business Number (BN) identifies your business, while the RP portion identifies your payroll deductions program. If a business needs more than one payroll account, the CRA can assign different reference numbers while keeping the same nine-digit BN.

Understanding this structure is useful when communicating with the CRA, making payments, filing payroll information returns, or giving information to your accountant or payroll provider.

Who Needs a Payroll Account?

Generally, you need to register for a payroll account if you are an employer, trustee, or payer of other amounts related to employment. CRA states that employers must register before the first remittance due date.

This can apply to incorporated businesses, partnerships, and other organizations that employ workers. The exact payroll obligations can vary depending on the nature of the payments and the worker’s circumstances.

A business should not wait until it has already missed a remittance deadline to create its account. Payroll registration should be treated as part of the initial hiring process.

For example, if a small corporation in Mississauga hires its first employee, the owner should consider payroll registration before the first source-deduction remittance becomes due.

When Should You Register?

CRA requires a new employer to register for a payroll account before the first remittance due date. Generally, the first remittance deadline is the 15th day of the month following the month in which the employer began withholding deductions, unless CRA assigns a different remittance frequency.

The practical approach is to register before paying your first employee, rather than waiting until the first payment deadline approaches.

Early registration gives you time to set up payroll software, collect employee information, determine the province of employment, prepare TD1 forms, and establish a process for calculating and remitting deductions.

Information Needed Before Registration

Before registering, have your business information available. This normally includes your business’s legal name, address, contact information, Business Number if you already have one, and details about the payroll activity.

If you do not already have a BN, CRA’s online registration process can generally allow you to obtain a Business Number and register certain CRA program accounts at the same time. CRA identifies Business Registration Online (BRO) as the fastest and easiest online method for registering a BN and payroll deductions account for Canadian resident businesses.

It is also useful to have an estimated payroll start date and basic information about the employees you expect to pay.

How to Register Online

For most Canadian businesses, online registration is the simplest option. CRA provides Business Registration Online for Canadian resident businesses, while non-resident businesses use the appropriate non-resident registration service.

If your business already has a BN, you generally do not need to obtain another BN just because you are opening a payroll account. Instead, you can add the payroll program account to the existing business registration.

CRA’s current registration information indicates that business owners can also access registration services through their CRA account.

Using Business Registration Online

The general process is straightforward:

1. Access CRA’s online business registration service.
2. Provide your business identification information.
3. Confirm your existing BN or register for one if necessary.
4. Select the Payroll Deductions (RP) program account.
5. Provide the requested payroll information.
6. Review the information before submitting.
7. Keep the confirmation and account details for your records.

CRA states that online registration is available for Canadian resident businesses through Business Registration Online.

If online registration is not available for your circumstances, CRA also provides alternative registration methods, including Form RC1 for certain program accounts.

Setting Up Employee Payroll

Once your payroll account is established, the next step is setting up each employee correctly.

CRA says employers should obtain the employee’s Social Insurance Number (SIN), determine the province of employment, and obtain the appropriate completed TD1 forms before paying an employee.

These details are important because payroll deductions depend on factors such as the employee’s income, province of employment, CPP status, EI status, and information provided on the employee’s TD1.

A payroll system should also be configured to handle taxable benefits, vacation pay, overtime, bonuses, and other compensation where applicable.

Calculating Payroll Deductions

Canadian employers generally need to calculate and withhold applicable income tax, CPP contributions, and EI premiums from employee remuneration.

For 2026, CRA provides updated Payroll Deductions Tables and a Payroll Deductions Online Calculator that employers can use to calculate federal and provincial or territorial income-tax deductions, CPP contributions, and EI premiums.

Payroll calculations should be performed using current CRA information rather than relying on outdated tax tables. This is especially important at the beginning of a new calendar year or when CRA publishes updated payroll rates.

Businesses should also review payroll software settings regularly to make sure they reflect the current year’s rules.

Remitting Payroll Deductions

Registering for the payroll account is only the beginning. Employers must remit the deductions they withhold to the CRA according to their assigned remitter type.

New employers are generally considered regular remitters unless CRA tells them otherwise. For regular remitters, payroll deductions are generally due by the 15th day of the month following the month in which the deductions were made.

For example, if employees are paid during September and source deductions are made, the regular remittance deadline is generally October 15.

However, remittance frequency can change based on the employer’s average monthly withholding amount and compliance history.

Understanding Remitter Types

CRA uses different remitter types to determine payroll payment schedules.

For example, regular remitters generally remit monthly. Certain eligible small employers can qualify for quarterly remitting, while businesses with larger payroll withholding amounts may have accelerated remittance requirements.

CRA’s current guidance includes thresholds for accelerated remitters. Businesses with an average monthly withholding amount of $25,000 to $99,999.99 may fall under accelerated remitter rules, while an average monthly withholding amount of $100,000 or more can result in more frequent remittance requirements.

Because these rules depend on the employer’s circumstances, businesses should verify their assigned remitter type through CRA’s online services.

Payroll Records and Compliance

Good payroll management requires more than making payments on time. Businesses should maintain records supporting employee compensation and deductions.

Records can include payroll registers, employee information, TD1 forms, timesheets, vacation records, benefit calculations, remittance confirmations, and year-end payroll information.

Keeping organized records makes it easier to correct errors and respond if CRA requests information.

Businesses should also reconcile their payroll liability accounts regularly. If the payroll register says one amount is owed but the accounting records show another, the discrepancy should be investigated before the next remittance.

T4 Slips and Annual Reporting

At the end of the calendar year, employers have additional reporting responsibilities. CRA’s 2026 business tax-deadline guidance states that employers with payroll accounts must file T4, T4A, T4A-NR and T4A-RCA information returns by the last day of February following the calendar year being reported.

T4 reporting summarizes employment income and applicable deductions for employees.

Businesses should reconcile annual payroll totals before submitting their T4 information return. Differences between payroll records, remittances, and T4 totals can create unnecessary complications.

Common Payroll Mistakes

One of the most common payroll mistakes is registering too late. Another is using outdated payroll deduction rates or incorrectly configuring payroll software.

Other problems can include:

• Missing payroll remittance deadlines
• Incorrect employee information
• Failing to obtain TD1 forms
• Miscalculating taxable benefits
• Incorrect CPP or EI deductions
• Poor payroll recordkeeping
• Failing to reconcile payroll accounts
• Incorrect T4 information
• Forgetting to report nil remittances when required

Late payroll remittances can also result in penalties and interest. CRA’s payroll guidance explains that penalties can apply when source deductions are remitted late.

When to Get Professional Payroll Help

Payroll can become complicated quickly as a business grows. Professional assistance may be useful when a company has multiple employees, bonuses, taxable benefits, commissions, different provinces of employment, shareholder-employees, or frequent payroll changes.

An accountant or payroll professional can help establish the CRA payroll account, configure payroll processes, calculate deductions, reconcile payroll liabilities, manage remittances, and prepare year-end information returns.

For a growing Canadian business, professional payroll support can also reduce the administrative burden on the owner and help maintain consistent compliance.

Conclusion

Setting up a CRA payroll account is an important step when your Canadian business begins paying employees. The registration process itself is relatively straightforward, but maintaining the account requires ongoing attention to payroll deductions, remittances, employee information, records, and year-end reporting.

For most Canadian resident businesses, CRA’s Business Registration Online service provides a convenient way to register for a payroll deductions account.

Once the account is active, employers should use current CRA payroll tables or calculation tools, establish a reliable payroll process, track remittance deadlines, and reconcile payroll records regularly.

A payroll account is not simply an administrative number. It is the starting point for a system that helps your business correctly handle employee deductions, CRA remittances, payroll records, and annual reporting.
