Only seven states have a flat tax. There are 32 states and the District of Columbia with a graduated income tax. And a graduated income tax is a long-standing principle of Catholic Social Teaching.
The National Conference of Catholic Bishops, in their letter Economic Justice for All, state that the tax system should be structured according to the principle of progressivity, so that those with relatively greater financial resources pay a higher rate of taxation. The inclusion of such a principle in tax policies is an important means of reducing the severe inequalities of income and wealth in the nation.
No one likes to pay more taxes! But our roads are a mess, college tuition is soaring, our K-12 schools need more money, Flint and other cities have failing water systems. It's obvious the state needs more revenue, but what to do?
One reasonable solution is to change Michigan's income tax from a flat tax (4.25%) to a graduated income tax. One legislator, Rep. Jim Townsend of Royal Oak, has suggested a rate of 3% on the first $20,000 , growing to 10% on income over $1 million. This plan would realize a reduction for 95% of filers!
Some people think that a flat rate is fair, but to raise enough income to do the things the state should do, would require a high enough percentage that it would be crippling for the poor. Townsend makes a point about fairness. The flat income tax gets sold as fair because everyone pays the same, but 4.25% of $100,000 is not as devastating a bite as 4.25% of an income of $30,000. Townsend also points out that the top 1% pay 5.9% of their income in state income tax, sales excise and property taxes, while middle and low-income people pay over 9% of their income in these various taxes.
