'Standard deductions' and 'itemized deductions' are alternatives. A standard deduction is the standard amount you may deduct from your adjusted gross income (AGI) to calculate taxable income. The amount depends on your tax filing status.
The IRS recommends deductions should be itemized when the total itemized amount exceeds the standard deduction for a given tax filing status. Itemized deductions begin to be lost when adjusted gross income reaches a certain amount.
For 2009 and 2010, a standard deduction is available in the following amounts: US$11,400 for married persons filing jointly; US$5,700 for married persons filing separately; US$8,350 (US$8,400 in 2010) for heads of households; and US$5,700 for single taxpayers. Taxpayers are also allowed to take personal exemptions of US$3,650 per person in 2009 and 2010. The Dependant's Standard Deduction is to be no more than the greater of $900 or $300 plus the individual's earned income.
An exemption is the amount a taxpayer can deduct from his or her adjusted gross income to calculate taxable income.The exemption phases out at higher incomes.
