Ontario Income Tax Calculator 2023 - 2026.

Ontario's income tax rates remain unchanged for 2026, but the income thresholds for the first two tax brackets are being adjusted. The province indexes its income thresholds, basic personal amount, and tax reduction amounts to the consumer price index (CPI). For 2025, Ontario's indexing factor was 2.8%, down from 4.5% in 2024. This indexing helps ensure the tax system accounts for inflation.

Ontario Provincial Income Tax Brackets

The Ontario Basic Personal Amount has increased each year, from $12,399 in 2024, to $12,747 in 2025, and $12,989 in 2026. If your taxable income falls below this amount, you pay no Ontario provincial income tax, though EI premiums and CPP contributions may still apply.

Ontario Tax Reduction

The Ontario Low-Income Tax Reduction is a credit that reduces or eliminates the provincial tax you must pay. The basic amount and the amount for each dependent child are indexed annually to the Ontario consumer price index.

The credit works by doubling the sum of the basic amount plus any applicable dependent child amounts, then subtracting your Ontario tax after surtax. If the result is positive, your Ontario tax is reduced by that amount — potentially to zero. If your income is too high, the reduction phases out entirely.

Low-Income Workers Tax Credit (LIFT)

Ontario residents having an individual adjusted net income of up to $50,000 and adjusted family net income of up to $82,500 receive the Low-Income Workers Tax Credit (LIFT). The credit amount for individuals with an income of up to $32,500 and families with an income of up to $65,000 is $875 or 5.05% of the employment income, whichever is lower.

For those whose income exceeds the thresholds, the maximum amount is reduced by 5% of the greater of your:

• adjusted individual net income over $32,500
• adjusted family net income over $65,000

1985-1995 (Increasing Taxes)

Following the 1982 recession, provincial governments across Canada found themselves with ballooning debt. As a result, Ontario needed to increase taxes to pay off the debt aggressively. During this period, Ontario calculated its provincial income tax as a percentage of federal tax owing (known as a "tax-on-tax" system), rather than applying tax rates directly to income as is done today.

The province increased this percentage from 48% to 58% by 1995, meaning that a resident owing $10,000 in federal tax would see their provincial tax rise from $4,800 to $5,800. Ontario also created an additional surtax for high-income earners. This approach differed from today's "tax-on-income" system, where provinces set tax rates that apply directly to taxable income rather than calculating them as a percentage of federal tax.

1996-2001 (Decreasing Taxes)

By 1996, Ontario had managed to pay off a significant portion of its debt due to the previous period's operating surplus. As a result, Ontario's tax policy changed dramatically. In 1996, a 30% reduction in personal income tax was announced, with an additional 20% reduction in 1999.

2002-2017 (New Taxes, Recession)

By the mid-2000s, Premier Dalton McGuinty (Liberal) was elected and rolled back a series of income tax cuts. Provincial funding increased for healthcare amidst the SARS pandemic, and so a new controversial tax, known as the Ontario Health Premium, was implemented. McGuinty's second term focused on easing the economic damage caused by the 2008 recession. This saw the lowest income tax rate cut by one percentage point. Kathleen Wynne (Liberal) was elected after McGuinty and increased taxes for high-income earners.

2018-Present

Premier Doug Ford (Conservative) was elected in 2018. His campaign included promises for income tax cuts across the board for low, middle, and high-income earners. Premier Ford had promised to cut the second income tax bracket from 9.15% to 7.32%. However, only the Low-Income Individuals and Families Tax Credit (LIFT) has been implemented, and the second income tax bracket remains at 9.15%.
