BC 5: Taxable income
or “How to calculate your taxable income by subtracting tax losses from your net income”
You could also call this:

“How to calculate the income tax you owe if you file a tax return”

You are a filing taxpayer if you need to file a tax return. Your income tax liability is the amount of income tax you need to pay for a tax year. To figure out your income tax liability, you multiply your taxable income by the basic tax rate.

If you have schedular income, which is a special type of income, your income tax liability is worked out differently. You can find out how it’s calculated in [section BC 7].

Sometimes, when you do the calculation, you might get zero or a negative number. If this happens, you don’t have to pay any income tax for that tax year. Your income tax liability is zero.
