WASHINGTON — A new top tax rate, higher Medicare taxes and the phaseout of deductions and exemptions could mean higher tax bills for wealthier Americans this year. Legally wed same-sex couples, meanwhile, may find the true meaning of the marriage penalty.
All taxpayers will have a harder time taking medical deductions.
In other changes for the 2013 tax year, the alternative minimum tax has been patched — permanently — to prevent more middle-income people from being drawn in, and there’s a simpler way to compute the home office deduction.
Tax rate tables and the standard deduction have been adjusted for inflation, as has the maximum contribution to retirement accounts, including 401(k) plans and individual retirement accounts, or IRAs.
The provisions were set by Congress last January as part of legislation to avert the so-called fiscal cliff of tax increases and spending cuts. “We finally got some certainty for this year,” said Greg Rosica, a contributing author to Ernst & Young’s “EY Tax Guide 2014.”
Nevertheless, the filing season is being delayed because of the two-week partial government shutdown last October. The Internal Revenue Service says it needs the extra time to ensure that systems are in place and working. People will be able to start filing returns Jan. 31, a week and a half later than the original Jan. 21 date.
HIGHER-INCOME TAXPAYERS: The tax legislation passed at the start of 2013 permanently extended the George W. Bush-era tax cuts for most people but also added a top marginal tax rate of 39.6 percent for those at higher incomes — $400,000 for single filers, $450,000 for married couples filing jointly and $425,000 for heads of household.
On top of that, higher-income taxpayers could see their itemized deductions and personal exemptions phased out and pay higher capital gains taxes — 20 percent for some taxpayers. And there are new taxes for them to help pay for the new health care law.
Each of these new taxes has different income thresholds.
An additional 0.9 percent Medicare tax, for example, kicks in on earnings over $250,000 for married couples filing jointly and $200,000 for singles and heads of household. Same for an extra 3.8 percent tax on investment income.
But the phaseout of personal exemptions and deductions doesn’t begin until $300,000 for married couples filing jointly and $250,000 for singles.
SAME-SEX MARRIAGE: Beginning this year, same-sex couples who are legally married will for the most part have to choose married filing jointly or married filing separately when doing their tax returns. This is true even if they live in a state that does not recognize gay marriage.
Many of these couples will now find themselves hit by the so-called marriage penalty, especially if both spouses work.
For example, with their incomes combined, they might hit the threshold for the extra Medicare taxes or the beginning of the phaseout of deductions and the standard exemption.
However, when it comes to estate taxes, the federal recognition of same-sex marriage will help legally married gay and lesbian couples. That was the issue in the Supreme Court decision in the case of Edith Windsor, who had to pay estate taxes after her lesbian spouse died.
In addition, health insurance purchased from an employer for a same-sex spouse can be paid pretax and excluded from income.
“Like opposite-sex couples, gay and lesbian married couples can qualify to use the head-of-household status, when kids are involved, where the spouses are living apart,” the IRS says.
Same-sex married couples also have the option of filing amended returns going back to 2010, using the married-filing-jointly status. Rosica said couples will have to look at their individual circumstances to see whether that’s beneficial from a tax perspective.
When it comes to filing state returns, same-sex married couples living in states that don’t recognize gay marriage most likely will have to file as singles. Because federal returns often are used as a starting point for state returns, that could force them to calculate their federal taxes twice, once for filing the federal return and once for figuring out their state taxes.
STOCK SALES: One simplification: Many investors will find it easier to report stock sales if the 1099-B forms they receive contain key details of the sale and the correct basis for computing gains and losses.
EDUCATION: Many credits and deductions were extended for 2013, including several for education. Among them: the American Opportunity Credit of up to $2,500 per student for tuition and fees and deductions for student loan interest and tuition-related expenses. Many of these are phased out at higher income levels.
Schoolteachers will still be able to deduct up to $250 in out-of-pocket expenses for books or other supplies.
MEDICAL EXPENSES: Taxpayers will still be able to deduct their medical expenses, but it will be more difficult for many to qualify. The threshold for deducting medical expenses now stands at 10 percent of adjusted gross income, up from 7.5 percent. There’s an exception, though, for those older than 65. For them, the old rate is grandfathered in until 2017.
HOME OFFICE DEDUCTION: Among the other changes for 2013, taxpayers who work at home will now have a simplified option for taking a home office deduction.
“You can claim this deduction for the business use of a part of your home only if you use that part of your home regularly and exclusively,” the IRS says.
But, if you sit at your kitchen table and check work email, it doesn’t qualify. “The regular and exclusive business use must be for the convenience of your employer and not just appropriate and helpful in your job,” according to the agency.
Until this year, you had to figure actual expenses for a home office, according to Weltman. “Starting with 2013 returns, if you’re eligible for the deduction, you can take a standard deduction of $5 per square foot, up to 300 square feet,” she said. The maximum deduction using this method is $1,500.
The IRS says people who take the simplified option will have to fill out one line on Schedule C, as opposed to a 43-line form.
Weltman likened the simplified home office deduction to the IRS deduction for business use of your car. “You can do your actual costs or the IRS mileage rates.”
The standard mileage rate for business use of a car in 2013 is 56.5 cents a mile, up from 55.5 cents.
ENERGY EFFICIENCY: If you made energy efficiency improvements to your home, such as installing new windows or a qualifying furnace or heat pump, you might be able to take an energy credit of 10 percent of the cost up to a lifetime maximum of $500.
However, of that total, the IRS says, “only $200 can be for windows, $50 for any advanced main air circulating fan, $150 for any qualified natural gas, propane, or oil furnace or hot water boiler, and $300 for any item of energy-efficient building property.”
There are additional credits for solar. However, the credit for plug-in electric vehicles has expired.
