Ontario Income Tax Rates and Brackets: 2024 & 2025

This section details the Ontario income tax rates and brackets for both 2024 and the projected 2025 tax year, along with combined federal and Ontario marginal tax rates, and key information regarding surtaxes and personal amounts.

Ontario Provincial Tax Brackets

Ontario’s provincial income tax system employs progressive tax brackets, meaning higher portions of income are taxed at higher rates. For 2025, the brackets have been adjusted for inflation, with the exception of the $150,000 and $220,000 thresholds.

2025 Tax Brackets:
- The first $52,886 of taxable income is taxed at 5.05%.
- Income between $52,886 and $105,775 is taxed at 9.15%.
- Income between $105,775 and $150,000 is taxed at 11.16%.
- Income between $150,000 and $220,000 is taxed at 12.16%.
- Income exceeding $220,000 is taxed at 13.16%.
2024 Tax Brackets:
- The first $51,446 of taxable income is taxed at 5.05%.
- Income between $51,446 and $102,894 is taxed at 9.15%.
- Income between $102,894 and $150,000 is taxed at 11.16%.
- Income between $150,000 and $220,000 is taxed at 12.16%.
- Income exceeding $220,000 is taxed at 13.16%.

Combined Federal and Ontario Marginal Tax Rates

The following highlights the combined marginal tax rates for various income types, including other income, capital gains, and Canadian dividends (eligible and non-eligible). These rates include Ontario surtaxes.

Key Considerations:
- Marginal tax rates for dividends are calculated based on actual dividends received, not the grossed-up taxable amount.
- Marginal tax rates for capital gains are calculated based on total capital gains, not taxable capital gains.
- Gross-up rates for eligible and non-eligible dividends are 38% and 15%, respectively.
- Surtaxes are calculated before dividend tax credits.
- The Ontario Health Premium is not included in these rates, and would increase the marginal tax rates.

Ontario Surtaxes

Ontario applies surtaxes to provincial income tax exceeding certain thresholds.

2025 Surtaxes:
- A 20% surtax applies to Ontario tax exceeding $5,710.
- An additional 36% surtax applies, bringing the total surtax to 56%.
- For individuals with only the basic personal amount, the surtax starts at a taxable income of $93,132.
2024 Surtaxes:
- A 20% surtax applies to Ontario tax exceeding $5,554.
- An additional 36% surtax applies.
- For individuals with only the basic personal amount, the surtax starts at a taxable income of $90,599.
The 56% total surtax increases the highest Ontario tax rate to 20.53% (13.16% x 1.56).

Basic Personal Amounts

Ontario Basic Personal Amount:
- 2025: $12,747 (taxed at 5.05%).
- 2024: $12,399 (taxed at 5.05%).
Federal Basic Personal Amount:
- 2025: $14,538 minimum / $16,129 maximum (taxed at 15%).
- 2024: $14,156 minimum / $15,705 maximum (taxed at 15%).
Federal and Ontario tax brackets and personal tax credit amounts are increased for 2025 by indexation factors, with the exception of the $150,000 and $220,000 ontario bracket amounts. The federal indexation factor is 1.027 and the Ontario indexation factor is 1.028.

Understanding Ontario Pay Statements and Payroll Practices

Providing clear and accurate pay statements is a fundamental responsibility for employers in Ontario. These statements, also known as pay stubs or statements of earnings, serve as a crucial record of employee compensation and deductions.

Required Information on Pay Statements:

When issuing payments to employees, you are legally obligated to provide a statement of earnings on or before the designated payday. This statement must include, at a minimum, the following details:

Pay Period: The specific dates covered by the payment.
Wage and Overtime Rates: The employee’s regular hourly wage rate and any applicable overtime rates.
Hours of Work: A breakdown of regular hours worked and overtime hours worked.
Gross Pay: The total earnings before any deductions, with separate listings for each component, such as:
- Regular wages
- Overtime pay
- General holiday pay
- Vacation pay
Deductions: A detailed list of all deductions from the employee’s earnings, along with the reason for each deduction (e.g., income tax, CPP, EI, benefit contributions).
Room and Board Amounts: Any amounts deducted for room and board provided by the employer.
Hours in Lieu of Overtime: Any hours taken off in lieu of overtime pay.
Net Pay: The final amount of wages paid to the employee after all deductions.

Electronic Pay Statements and Privacy:

Electronic pay statements are acceptable, provided that employees have confidential access to view and print them. Employers must ensure the privacy and confidentiality of employee payroll information, in compliance with relevant privacy legislation.

Record Keeping:

It is essential to maintain accurate employment records, including pay statements, for a minimum of three years.

Pay Frequency and Paydays:

Employers have the flexibility to determine the frequency of paydays, which can be weekly, bi-weekly, semi-monthly, monthly, or any other specified period. Bi-weekly pay periods, with paydays typically falling on Fridays, are commonly used.

Payment of Wages:

All wages earned within a pay period must be paid to employees by the designated payday. It is crucial to adhere to this schedule to ensure timely compensation for employees.

Prohibited Wage Deductions, Leaves of Absence, Workers' Compensation, and Termination Notices in Ontario

This section provides crucial information for Ontario employers regarding prohibited wage deductions, various types of leaves of absence, workers’ compensation obligations, and termination notice requirements.

Prohibited Wage Deductions:

Employers in Ontario are legally restricted from making certain deductions from an employee’s wages, even if there is a collective agreement or a written agreement in place. These prohibited deductions include:

Deductions for faulty work performed by an employee.
Deductions for cash shortages or property loss if someone other than the employee had access to the cash or property.
Deductions for cash shortages resulting from an employee not collecting the full purchase price from a customer.
Deductions to cover the cost of purchasing, using, repairing, or cleaning uniforms or special clothing that an employee is required to wear at work.

Leaves of Absence:

While Ontario does not mandate paid sick leave, employers may offer it at their discretion through employment contracts. The federal government does have its own rules regarding paid sick days. There are other types of leaves of absences that are protected by the Ontario Employment Standards Act.

Workers' Compensation (WSIB):

When an employee is injured on the job, employers have specific obligations under the Workplace Safety and Insurance Board (WSIB).

Employers are required to report workplace injuries to the WSIB within 72 hours.
WSIB coverage is mandatory for the construction industry, with some exceptions for home renovation work.
Employers are responsible for providing first aid, reporting accidents, and maintaining incident records.
Failure to report injuries may result in penalties.
Employers must pay the injured worker’s full wages for the day of the injury.
If the employee is unable to work beyond the day of the accident, WSIB provides compensation payments, covering 85% of the employee’s take-home pay, up to a maximum insured wage.

Termination Notice:

When terminating an employee’s employment, employers must comply with provincial notice requirements.

Notice is required if an employee has been continuously employed for at least three months.
The required notice period varies based on the length of the employee’s employment.
For mass layoffs, involving a significant number of employees, longer notice periods are required.
During the statutory notice period, employers must:
- Maintain the employee’s wage rate and employment terms.
- Continue contributing to employee benefit plans.
- Pay the employee their regular wages.
Employers may provide termination pay in lieu of notice, which is a lump sum payment equivalent to the wages the employee would have earned during the notice period.
