WASHINGTON -- While the tax package that Congress passed New Year's Day will protect 99 percent of Americans from an income tax increase, most of them will still end up paying more federal taxes in 2013.
That's because the legislation did nothing to prevent a temporary reduction in the Social Security payroll tax from expiring. In 2012, that 2-percentage-point cut in the payroll tax was worth about $1,000 to a worker making $50,000 a year.
The Tax Policy Center, a nonpartisan Washington research group, estimates that 77 percent of American households will face higher federal taxes in 2013 under the agreement negotiated between President Barack Obama and Senate Republicans. High-income families will feel the biggest tax increases, but many middle- and low-income families will pay higher taxes too.
Households making between $40,000 and $50,000 will face an average tax increase of $579 in 2013, according to the Tax Policy Center's analysis. Households making between $50,000 and $75,000 will face an average tax increase of $822.
"For most people, it's just the payroll tax," said Roberton Williams, a senior fellow at the Tax Policy Center.
The tax increases could be a lot higher. A huge package of tax cuts first enacted under President George W. Bush was scheduled to expire Tuesday as part of the "fiscal cliff." The Bush-era tax cuts lowered taxes for families at every income level, reduced investment taxes and the estate tax, and enhanced a number of tax credits, including a $1,000-per-child credit.
The package passed Tuesday by the Senate and House extends most the Bush-era tax cuts for individuals making less than $400,000 and married couples making less than $450,000.
Obama said the deal "protects 98 percent of Americans and 97 percent of small business owners from a middle-class tax hike. While neither Democrats nor Republicans got everything they wanted, this agreement is the right thing to do for our country."
The income threshold covers more than 99 percent of all households, exceeding Obama's claim, according to the Tax Policy Center. However, the increase in payroll taxes will hit nearly every wage earner.
Social Security is financed by a 12.4 percent tax on wages up to $113,700, with employers paying half and workers paying the other half. Obama and Congress reduced the share paid by workers from 6.2 percent to 4.2 percent for 2011 and 2012, saving a typical family about $1,000 a year.
Obama pushed hard to enact the payroll tax cut for 2011 and to extend it through 2012. But it was never fully embraced by either party, and this time around, there was general agreement to let it expire.
The new tax package would increase the income tax rate from 35 percent to 39.6 percent on income above $400,000 for individuals and $450,000 for married couples. Investment taxes would increase for people who fall in the new top tax bracket.
High-income families will also pay higher taxes this year as part of Obama's 2010 health care law. As part of that law, a new 3.8 percent tax is being imposed on investment income for individuals making more than $200,000 a year and couples making more than $250,000.
Together, the new tax package and Obama's health care law will produce significant tax increases for many high-income families.
For 2013, households making between $500,000 and $1 million would get an average tax increase of $14,812, according to the Tax Policy Center analysis. Households making more than $1 million would get an average tax increase of $170,341.
"If you're rich, you're almost certain to get a big tax increase," Williams said.

Residential Energy-Efficiency Credits
No tax breaks for being green in 2012. Homeowner investments in energy-efficient double-pane windows or high-efficiency refrigerators, <a href="http://www.energytaxincentives.org/">don't get any tax benefit</a>. More than 43.5 million Americans have filed and received this benefit, with an average reduction in tax liability of $765.84, according to H&R Block.
Mortgage Insurance Premiums
Bad news for homeowners: They cannot write off mortgage insurance premiums on 2012 tax returns. Congress can act to reauthorize these deductions retroactively to Jan. 1, 2012, and extend them through the end of 2013, but that would cost the government $1.3 billion over the next decade, the <a href="http://articles.latimes.com/2012/oct/07/business/la-fi-harney-20121007">Los Angeles Times reports</a>.
Taxpayers who have out-of-pocket adoption expenses or who adopted a child with special needs can only claim the adoption credit to the extent of their tax liability. While the portion of the credit not taken into account in 2012, up to $12,650 per child, is carried forward to future years, the benefit is no longer fully refundable, according to tax experts.
Alternative Minimum Tax
If the alternative minimum tax legislation is not retroactively patched for 2012, current law could result in an increased tax liability for up to 34 million Americans. According to a study by the Tax Institute at H&R Block, an average family making $85,000 with children in college could see their tax liability soar from a $1,056 refund to owing $1,400.
American Opportunity Tax Credit
Tuition bills will be higher starting on Jan. 1 because families will lose the $2,500 American Opportunity Tax Credit, which ends in 2012 unless Congress takes action. More than 2.4 million Americans claimed this deduction in 2009, resulting in a combined decrease in taxable income of $5.4 billion, according to tax experts.
Payroll Tax Credit
Paychecks will be smaller starting Jan. 1, 2013. An American making $50,000, for example, will lose $80 in monthly pay after the credit ends. The temporary credit also has lowered the amount workers contributed to Social Security by 2 percent.
Educator Expense Deduction
Teachers lose their $250 maximum deduction on expenses related to buying school supplies. This credit expired at the end of 2011, and teachers won't be able to claim this benefit on their 2012 taxes unless Congress takes action. In 2009, more than 3.8 million teachers claimed this benefit for a combined deduction of $9.7 billion, according to H&R Block.
Sales Tax As An Itemized Deduction
Taxpayers will no longer have the option of claiming an itemized deduction for state sales tax in lieu of state income tax. This expiration will have a greater impact on taxpayers who reside in a state with sales tax, but no income tax, including Alaska, Florida, Texas, Nevada, Washington, South Dakota, and Wyoming.
IRA Retirement Funds
Taxpayers over age 70½ no longer have the option of directing their income from an IRA distribution to a charitable organization. Starting this year, older taxpayers must include the distribution in income and claim a charitable deduction, resulting in a potentially higher tax bracket and a need to itemize instead of claiming the standard deduction, according to H&R Block.
As if losing all those tax credits was not bad enough, the earliest date to file a 2012 tax return electronically has moved back to Jan. 22, 2013. As the IRS has indicated that refunds could take as long as 21 days to process this year, a refund in January to cover Christmas credit card payments, winter heating bills, or rent is unlikely.
