WASHINGTON (AP) — A typical middle-income family making $40,000 to $64,000 a year could see its taxes go up by $2,000 next year if lawmakers fail to renew a lengthy roster of tax cuts set to expire at the end of the year, according to a new report Monday

Taxpayers across the income spectrum would be hit with large tax hikes, the Tax Policy Center said in its study, with households in the top 1 percent income range seeing an average tax increase of more than $120,000, while a family making between $110,000 to $140,000 could see a tax hike in the $6,000 range.

All told, the government would reap more than $500 billion in new revenue if a full menu of tax cuts were allowed to expire. The expiring provisions include Bush-era cuts on wage and investment income and cuts for married couples and families with children, among others. Also expiring is a 2 percentage point temporary payroll tax cut championed by President Barack Obama.
