Depending on a taxpayer’s province of residence, the first $9,000 to $16,000 of income they earn is tax free and as their income increases above that threshold, the rates of tax also increase. A taxpayer’s marginal tax rate is the rate they pay on the net dollar of their income. A graduated rate estate benefits from low tax rates on low income and increasing tax rates as income rises, so can provide an additional set of low tax brackets beyond that of the beneficiaries. As a result, a graduated rate estate can save tax for high-income beneficiaries if the estate’s income is significant.
