Worked Example

Let's calculate the corporate tax for a company with the following details:

Revenue: $1,000,000
Salaries and wages: $600,000
Rent: $100,000
Utilities: $50,000
Insurance: $30,000
Depreciation: $80,000
Canada Employment Amount credit: $100,000

First, calculate the total deductions:

Total Deductions = Salaries + Rent + Utilities + Insurance + Depreciation

Total Deductions = $600,000 + $100,000 + $50,000 + $30,000 + $80,000 = $860,000

Next, calculate the taxable income:

Taxable Income = Revenue - Total Deductions + Credits

Taxable Income = $1,000,000 - $860,000 + $100,000 = $240,000

Finally, calculate the corporate tax:

Corporate Tax = Taxable Income × Corporate Tax Rate

Corporate Tax = $240,000 × 12.25% = $29,400

Therefore, the corporate tax for this company is $29,400.
