RRSP contributions (up to 18% of income)
Medical expenses (over 3% of income)
Donations to registered charities
Home office expenses
Tuition and education expenses

Tax Credits

Tax credits directly reduce the amount of tax you owe. In 2012, common Ontario tax credits included:

Basic personal amount ($9,000)
Age amount (up to $2,200 for seniors)
Spouse or common-law partner amount ($9,000)

These credits can significantly reduce your tax liability, especially for lower-income taxpayers.

Worked Example

Let's calculate the tax for a single taxpayer with $50,000 in taxable income in 2012.

First $39,994 at 10.5%: $39,994 × 0.105 = $4,244.39
Next $10,006 at 14.5%: $10,006 × 0.145 = $1,450.79
Total tax: $4,244.39 + $1,450.79 = $5,695.18

After applying the basic personal amount credit of $9,000, the net tax payable would be $5,695.18 - $9,000 = -$3,304.82. This means the taxpayer would receive a refund of $3,304.82.

Frequently Asked Questions

What is the difference between federal and provincial taxes in Ontario?

In Ontario, you pay both federal and provincial income taxes. The federal tax rates are applied to your taxable income, while the provincial rates are applied to the amount remaining after federal tax credits. The Ontario tax brackets are progressive, meaning higher income levels are taxed at higher rates.

How do I claim the basic personal amount credit?

The basic personal amount credit is automatically applied to your tax return. You don't need to take any special action to claim it, as it's part of the standard tax calculation. However, you must meet the eligibility requirements, such as being a resident of Ontario for the entire year.

Are there any changes to the Ontario tax rates for 2013?

Yes, the Ontario government introduced several changes to the tax rates for 2013. The basic personal amount was increased to $10,000, and the top marginal tax rate was reduced from 21% to 20%. These changes were part of the government's effort to reduce the overall tax burden on Ontarians.
