Final answer:
The RL-1 slip is specific to Quebec for reporting salaries, wages, and deductions in the province, whereas the T4 slip is for reporting income paid to employees in all of Canada, and the T4A is for reporting other payments like pensions or payments to subcontractors.
Step-by-step explanation:
The differences between the RL-1 and the T4/T4A slips generally revolve around the tax reporting requirements for different types of income in Canada.
The T4 slip is a tax form used in Canada to report the income you paid to employees along with the amount of income tax that was deducted. This form is required for all employees working in Canada and is issued by employers to their employees. In contrast, the T4A slip is similar to the T4 but is used for reporting other amounts paid or deemed to be paid to individuals who are not employees, such as subcontractors or pension income.
The RL-1 slip is a Quebec-specific form which resembles the T4 slip but it is used for reporting employment income and deductions in the province of Quebec. The RL-1 slip must be completed by Quebec employers or payers to report amounts such as salaries, wages, tips, and other compensation paid to employees along with the income tax and contributions to the Quebec Pension Plan (QPP) and the Quebec Parental Insurance Plan (QPIP).
Overall, the main differences lie in the specific purposes they serve, with each form catering to different types of income and deductions, and in the case of the RL-1, being specific to the province of Quebec.
