Summary of the project, initiative or change

Overview of the Program or Activity

The objective of the TAE program (payroll) is to maintain the integrity of the tax system regarding:

It does this through a combination of taxpayer education and responsible enforcement, including examining employers’ books and records. 

To increase and enhance voluntary compliance, the program promotes employer awareness and understanding of tax laws and obligations as provided in the:

Trust accounts examination officers (TAEOs) conduct examinations of taxpayer's books and records to ensure employers comply with the:

If payroll accounts are non-compliant, other program areas may request a trust accounts examination (TAE). Additionally, the Workload Development and Business Intelligence Section of the Business Compliance Directorate develops the TAE workload. That directorate performs risk assessments to determine whether an employer will comply with their employer reporting obligations.

Under the Canada Pension Plan and the Employment Insurance Act, the CRA is responsible for determining:

What’s New

The 10% temporary wage subsidy for employers (TWS) is a 3-month measure administered by the Employer Accounts program. This measure allows eligible employers to reduce the amount of payroll deductions they need to remit to the CRA. Eligible employers are those that paid eligible remuneration to an eligible employee from March 18 to June 19, 2020. The Employer Accounts program will send some non-compliant accounts to TAE program to resolve. The TAE program will verify and validate amounts an employer claimed for the subsidy and how they applied the subsidy to each pay period in their payroll account. The program will ask the taxpayer for a copy of Form PD27, 10% Temporary Wage Subsidy Self-identification Form for Employers, and complete a review to confirm the employer is eligible.

In 2019, desk examinations become a part of the TAE program, and the program continues to use the FileNet system to store documents received from employers, GST/HST registrants, and their authorized representatives.

In 2020, the CRA established a digital fax line for employers to submit their books and records. Documents received by digital fax are stored in FileNet.

As of January 2021, each representative authorized by a firm, a business, or a group must get their own representative identifier (RepID) and provide it to the CRA before they can represent their client. Businesses can manage who can access their tax information online using My Business Account. This includes authorizing or deleting a representative and monitoring any transactions a representative performs.

For offline access (phone, fax, mail, or in person) for a representative, a business must submit the AUT-01 - Authorize a Representative for Offline Access Form. The AUT-01 form replaced Form RC59, Business Consent. This new procedure is a proactive initiative put in place to support the CRA’s legal obligation to protect confidential taxpayer information. The Represent a Client Management Enquiries application allows the TAE program to authenticate the representative by cross‑referencing a representative’s RepID with the CRA’s records.

The Vancouver Island and North Tax Services Office has started a monitoring project to determine the level of tax compliance of participants receiving contracts to work. As a result, the office created a local application to:

The application’s database contains external public information and internal information from the mainframe system. It is designed for data analysis, intelligence gathering, risk identification, file management, audit, and collections to ensure taxpayers are reporting and paying the appropriate tax for each program. The application offers specialized query and reporting functions for multiple users to efficiently review the population of taxpayers across business lines and serves to break down silos and optimize the existing program activities. The application allows different program line users, including the TAE program, to verify compliance for entities and individuals, add or update information, and get reports in real‑time.

The interim Canada dental benefit is meant to help lower dental costs for eligible families earning less than $90,000 per year. Parents and guardians may be eligible if they pay for dental care for a child under 12 years old who does not have access to a private dental insurance plan. Beginning with the 2023 tax year, issuers (including employers and pension plan administrators) of T4 or T4A slips must annually report whether a payee or any of the payee’s family members were eligible to access dental insurance due to their current or former employment. This includes dental coverage of any kind, including health spending and wellness accounts. According to legislation and procedures already in place, not reporting this information may result in financial penalties.

To support these new reporting requirements, the CRA made the following changes to the T4 and T4A slips:

Program letters are being updated to ask the employer whether a dental plan was offered to employees and to whom it was offered. The TAE program will be ensuring employers fill out the new boxes on the slips. As well, it will file and amend slips during the course of exams as required in line with the new legislative policies.

Scope of the Privacy Impact Assessment

This PIA identifies and assesses privacy risks to personal information relating to activities of the TAE program. The activities of the Employer Accounts program and ECA program have been assessed under separate PIAs. Activities related to creating workloads, identifying unknown non‑compliance, and delivering business intelligence solutions in support of the TAE program are assessed in the Workload Development and Business Intelligence: Business Compliance Programs PIA. The Collections and Verification Business Intelligence PIA assesses the development of the business intelligence and related data solutions and services for the Employer Accounts program.

Some references to the GST/HST examination program and the air traveller’s security charge have been removed because those programs are covered under the Corporations and GST/HST Compliance Programs PIA.

Risk identification and categorization

A) Type of program or activity

Compliance / Regulatory investigations and enforcement  

Level of risk to privacy: 3

Details:

The program uses personal information to review the books and records of businesses to ensure they are compliant with filing, reporting, and withholding requirements and to assess deficiencies when applicable. This includes validating temporary wage subsidy claims. In addition, the program uses this information to review payroll and GST/HST accounts for taxable benefits and the proper characterization of workers.
