WASHINGTON – 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.

Taxpayers across the income spectrum will get slammed with increases totaling more than $500 billion – a more than 20 percent increase – with nine of 10 households being affected by the expiration of tax cuts enacted under both President Barack Obama and his predecessor, George W. Bush.
