Explanation of the Chart

Consider a hypothetical couple, James and Joan Canada. The table displays two scenarios for James and Joan's family income. In Scenario 1, James and Joan each earn $40,000 and receive equal personal exemptions of $7,756. Neither James nor Joan receives the spousal exemption, as it only applies if a spouse earns less than $7,245. In addition, both partners have the same portion of their incomes taxed at the various income tax rates. James and Joan pay equal amounts of income tax for a combined total of $11,256.

In Scenario 2, one partner (James) is the sole breadwinner. Since Joan does not earn income, James is eligible for a spousal exemption of $6,856 in addition to his $7,756 personal exemption. Their combined exemption is less that it was in Scenario 1. Further, since James is subject to the same tax brackets as an individual would be, a greater portion of his family income is taxed at higher rates. The combined effect of the lower exemption and the increased amount of income taxed at higher rates increases the income tax paid by James and Joan. The difference: taxes paid by the dual-income family are $2,743 less than those paid by the single-income family. This difference has been coined "The Leave-it-to-Beaver tax penalty."
