Whew, that was close! At the last minute (actually a few hours after the last minute), the House of Representatives prevented the United States from falling off the "fiscal cliff" by passing the American Taxpayer Relief Act of 2012.
What does this mean to you? As far as income taxes go, for the vast majority of taxpayers it means more of the same. However, everybody who works will have to pay more Social Security taxes than they have over the last two years.
Unless you're in the top 1% income level, the new tax law does not increase or otherwise change your income tax rates from last year. The rates in effect for the last ten years are now permanent. Had Congress not acted, tax rates for everybody would have gone up to their pre-2001 levels.
The big change is for very high income taxpayers: those with incomes over $400,000 ($450,000 if married, filing jointly). The top income tax rate for these taxpayers goes up from 35% to 39.6%. But they will only pay this new rate on the portion of their taxable income above $400,000 or $450,000. Thus, for example, a single individual with taxable income of $401,000 in 2013 would pay $46 more in income tax due to the 4.6% raise.
For the past two years, all working people have enjoyed a Social Security tax "holiday"--Social Security taxes were cut by 2% for everyone for 2011 and 2012. This holiday was always intended to be a temporary measure to help people during the recession. However, some people wanted to extend it for another year. This has not happened. The holiday has expired without any extension. This means that Social Security taxes will go back up to their old rates: employees will have to pay a 6.2% Social Security tax up to the annual wage ceiling of $113,700 in 2013. Self-employed people must pay a 12.4% Social Security tax on their net self-employment income up the same ceiling amount.
Thus, for example, a worker who earns $50,000 in 2013 will have to pay an additional 2% Social Security tax on that income--$1,000. The maximum increase for a person with $113,700 or more in income is $2,274.
Special capital gains tax rates apply if you earn a profit from selling a "capital asset" such as corporate stock or your house. For singles with income above $400,000 and marrieds filing jointly with income over $450,000, the capital gains rate goes up from 15% to 20%. For everybody else, the rates remain the same which means people in the 25%, 28%, 33% and 35% brackets pay a 10% capital gains tax. The rate remains zero for people in the 10% and 15% tax brackets.
However, a new 3.8% investment tax took effect on January 1 as part of the funding for Obamacare. Singles with income above $200,000 and marrieds filing jointly with income over $250,000 must pay a 3.8% tax on their net investment income. This is added to the regular capital gains rate. Thus, the top rate will be 23.8% for those in the $400,000/$450,000 income levels.
Qualified dividends are taxed at the same rate as capital gains.
Another highly technical change that only affects high-income taxpayers is reinstatement of phase-outs of personal exemptions and itemized deductions for single taxpayers with income over $250,000 and marrieds filing jointly with income over $300,000. This will increase their income taxes by about 1%.
Only estates worth more than $5 million will be subject to federal estate taxes--the same as last year. The top estate tax rate was increased from 35% to 40%.
Certain tax credits that were scheduled to expire or be reduced in amount have been extended. These primarily benefit low-income taxpayers and include the following:
Certain popular itemized tax deductions scheduled to expire at the end of 2012 have also been extended by two years. These include:
