Five Changes That Could Affect Your 2010 Tax Bill
1. Inflation Adjustments. While inflation has been low, there have still been some increases to tax brackets. This means you were able to earn more in 2010 than in 2009 without being pushed into a higher tax bracket for 2010.
Because Congress did not okay these extensions until late in 2010, the IRS needs more time to adapt their systems. Taxpayers claiming these above-the-line deductions or who itemize their personal deductions cannot e-file before February 14.
Note: Not all expired rules were extended. Don't look for these 2009 breaks on your 2010 return: an additional standard deduction for real estate taxes and net disaster losses, an exclusion from income for some unemployment benefits, and a sales tax deduction on new car purchases.
3. Deferral for Roth IRA Conversion Income. If you converted a traditional IRA to a Roth IRA in 2010, you can automatically defer half of the income from the conversion to 2011 and half to 2012 by not reporting the income on your return. However, if you want to include the income in 2010 -- because it can be offset by a net operating loss or for some other reason -- you can choose to do so.
4. No Phase-Outs for High-Income Taxpayers. In the past, if your income exceeded certain limits, your personal exemptions and itemized deductions were reduced. In 2010, there is no such reduction, so you can enjoy all of the write-offs you're entitled to.
5. Alternative Minimum Tax (AMT) Relief. The AMT exemption for 2010 is increased to $72,450 for taxpayers filing jointly, $47,450 for single taxpayers and those filing as head of households, and $36,225 for married couples filing separately; this keeps more taxpayers from having to pay this tax. What's more, nonrefundable personal credits -- such as the dependent care credit, the credit for buying a hybrid car and the home energy property credit -- can be used to offset not only regular tax but also the AMT.
If, for any reason, you can't file your 2010 by April 18, 2011, just ask for a filing extension to avoid late filing penalties. This will give you until Oct. 17, 2011, to file the return and avoid late-filing penalties. Use IRS Form 4868, which can be filed electronically or by paper. But the filing extension does not give you more time to pay your taxes, so pay as much as you think you'll owe.
