An Associated Press computer analysis shows that Michigan families have seen their state tax bills drop by as much as a fourth over the past 15 years.
The cuts are saving them hundreds, even thousands, of dollars each year.
Some of the biggest savings have come through the lower property tax bills that homeowners have paid since Proposal A passed in 1994.
But income tax cuts passed earlier this decade also have helped.
Since 2000, residents have seen their state tax bills go down by around five percent.
The decreases have been good for Michigan families. But they've also made it harder to balance the state budget, which this year has an $800 million shortfall.
The issue of whether Michigan residents are overtaxed or can afford to pay more to avoid budget cuts is being hotly debated.
