Bad Debt

A tax deduction is an amount subtracted from your income before tax is worked out, so it reduces the income being taxed rather than the tax bill directly. Its worth depends on your marginal rate: the higher the rate, the more the deduction saves. Common examples are RRSP contributions, child care costs, union dues, moving expenses and business expenses. Credits work the other way, reducing the tax calculated on that income.

Multiply the assessed value of the property by the tax rate for its property class. Assessment is set by a provincial assessment authority on its own cycle and increases are often phased in, so the value lags the market. The rate is set each year by the municipality out of its budget, with an education portion added by the province. Both figures appear on your notice, which is why identical homes in different municipalities carry different bills.

Yes, indirectly. Provincial assessment authorities value a home from its characteristics, including lot size, living area, age, construction quality, bedrooms and bathrooms, and recent sales of comparable homes nearby. Your municipality then multiplies that assessed value by its rate. So a bigger lot or more finished square footage generally means a higher assessment and a higher bill, while bedroom count alone matters less than total area. Your assessment notice lists the details on record.

You claim credits on your return, and they are applied against the tax already calculated on your taxable income. Non-refundable federal and provincial credits are each worked out by multiplying the eligible amount by the lowest rate for that jurisdiction, so the same claim is worth different money at each level. Unused amounts are lost at year end unless the particular credit allows a carry-forward or a transfer to a spouse. Refundable credits are paid whether or not tax is owing.
