Ready or not, big changes lie ahead for virtually every U.S. taxpayer next year.
Tax cuts put into place under the Bush administration that slashed rates on wages, dividends and capital gains are set to expire at the end of 2012. The Social Security payroll tax cut enacted this year also will end, as will the exemption of millions of middle-class families from the alternative minimum tax.
It behooves you to spend a little time examining your own situation ahead of time. A midyear tax review always makes sense, but more so than ever this year.
Even some basic housekeeping and preparations for the tax overhaul in Washington can save money and help you avoid end-of-the-year angst over the inevitable 11th-hour congressional tussle over what to do next.
A simple do-it-yourself checkup can be performed in less than an hour. All you really need is your June 30 pay stub -- the one that goes through the end of this week -- and your 2011 tax return.
Start by multiplying your year-to-date earnings by two to get an estimate of 2012 income and compare it to last year's final figure. The goal is to have a better idea of how your tax situation will look next year at tax time, says Mark Steber, chief tax officer for Jackson Hewitt Tax Services.
Do the same with your withholding. The IRS recommends reviewing your withholding during the year to make sure it's in line with what your tax liability is likely to be. There's a withholding calculator on its website, http://www.irs.gov. You may wish to tweak the amount you withhold if it looks like you might either owe money or appear headed for an unwisely large refund.
Now review what might have changed this year. Do you have a new family member? Did one move out? Did you change jobs or move? Get married or divorced? Consulting with a tax professional would be the most reliable way to figure out the impact of such changes. But you should be able to get at least a sense on your own of where you stand at midyear.
While you're at it, take a look at your savings and any 401(k), IRA or Roth IRA that you have. Will you be able to max out 2012 contributions? Make sure you're at least contributing enough to get the company match in your 401(k). And keep an eye on your medical reimbursement account, if you have one, to make sure you're taking full advantage.
"With six months remaining in the year, there are still opportunities to lower your 2012 tax liability via withholding changes, increase in charitable contributions, retirement savings and more," says Kathy Pickering, executive director of the Tax Institute at H&R Block.
So many changes are being discussed for next year that the natural tendency is to wait until they're all final before sorting it all out. But tax experts say you could leave tax savings on the table if you don't do some planning ahead of time.
Without trying to forecast outcomes, one good step to take now is to identify and start following a reliable resource or two for tax information -- IRS.gov, a blog, a columnist, a favorite financial site. Then as the changes take shape, you can act quickly.
Here are some of the biggest changes brewing and some planning considerations to take into account:
-- Payroll tax.
A temporary payroll tax cut that has been of benefit to nearly every wage earner in 2011 and 2012 is set to expire, costing the average family an additional $1,000 a year.
"People should think about how they're going to budget with a smaller paycheck next year," says Elda Di Re, partner in Ernst & Young's personal finance services group.
-- Capital gains.
Without congressional action, the capital gains tax will rise from to 20 percent from 15 percent.
Anyone considering an action that will trigger a major capital gain, such as selling stock or a vacation home, may want to consult with a professional about the potential difference between closing a transaction this year and next.
The tax on dividends will go from the current 15 percent to your individual tax rate, meaning as high as 39.6 percent for upper-income taxpayers.
Higher tax rates might make dividend stocks that you are considering adding to your portfolio less appealing, although it doesn't necessarily mean selling ones you already own.
If the Supreme Court does not strike down the whole health care reform law in its ruling expected Thursday, millions of wealthy taxpayers face tax increases related to Medicare.
High-income individuals would pay a surtax of another 0.9 percentage points on earned income over $200,000, or $250,000 for married couples. High-income households also face a new 3.8 percent tax on investment income. Congress approved that tax to help finance the health care overhaul.
Taxpayers should get a better read on this one once the court verdict is issued.
-- Alternative minimum tax.
The alternative minimum tax typically has affected taxpayers making more than $200,000, thanks to so-called "patches" that have annually exempted middle-income families. Unless extended retroactively, the AMT patch already has expired for 2012, reducing exemption amounts precipitously.
It's worth checking with a financial adviser to see how much you might be subject to under this complicated law, which targeted loopholes used by wealthy taxpayers when it was created in 1969 but has been changing in scope.
-- Estate tax.
The estate tax rate would rise to 55 percent from the current 35 percent and the exemption level would fall to $1 million from $5 million, subjecting many more estates to it.
If you have a large estate and want to remove some taxable assets from it, this might be a good year to do any planned gifting, says Mark Luscombe, principal federal tax analyst for the CCH consulting firm in Riverwoods, Ill.
-- Tax breaks.
Dozens of other tax credits and deductions that are routinely renewed each year already expired at the end of 2011. If Congress fails to act, individuals would lose federal tax breaks for paying local sales taxes, buying energy efficient appliances and using mass transit, among others.
The big picture is there are no clear answers at the moment.
But if you believe tax increases are on the way for 2013, it may be prudent to accelerate income and postpone deductions this year, says Luscombe. The reverse of the usual tax strategy, it makes sense when someone is headed for a higher tax bracket the following year.
Besides selling assets that would result in a capital gain, ways to accelerate income include converting a traditional IRA to a Roth IRA and taking distributions from an IRA or retirement plan, so long as it won't result in an early-withdrawal penalty. Postponing deductions could mean waiting to make a charitable gift until next year, when the deduction could have more value, or deferring realization of a capital loss.
