This happy state of affairs will continue through 2010 unless Congress changes the rules, which could easily happen if the Democrats seize full control in Washington. That means you should make every effort to take advantage of the 0% rate this year. Wait until next year and it just might be too late.
Here's how it works.
Say you file jointly, have two dependent kids and claim the standard deduction for 2008. You could report up to $90,000 of adjusted gross income this year (including long-term capital gains and dividends) and still be within the 15% rate bracket. Your taxable income would be $65,100, which is the top of the 15% bracket for joint filers.
Say you're divorced, use head of household filing status, have two dependent children, and claim the standard deduction for 2008. You could have up to $62,150 of adjusted gross income this year (including long-term capital gains and dividends) and still be within the 15% rate bracket. Your taxable income would be $43,650, which is the top of the 15% bracket for heads of households.
Say you're single with no kids and claim the standard deduction for 2008. You could have up to $41,500 of adjusted gross income (including long-term capital gains and dividends) and still be within the 15% rate bracket. Your taxable income would be $32,550, which is the top of the 15% bracket for singles.
If you itemize deductions, your adjusted gross income (including long-term capital gains and dividends) could be even higher, and you could still be within the 15% rate bracket.
Remember: The adjusted gross income figures I'm quoting are after subtracting any write-offs allowed on page 1 of your 2008 Form 1040 (these are the so-called above-the-line deductions). Among others, these write-offs include deductible retirement account contributions, health savings account (HSA) contributions, self-employed health-insurance premium costs, alimony payments, moving expenses and more. If you have some above-the-line deductions, your income can be that much higher, and you'll still be within the 15% rate bracket.
Example: Married Joint Filer
Say you're a married joint filer with two dependent children and will report the following on your 2008 Form 1040:
A salary of $105,000
$10,000 401(k) contribution at work
$5,000 in above-the-line deduction for HSA contributions
$16,000 in itemized deductions
$14,000 in write-offs for four personal exemptions ($3,500 each)
Your taxable income will be $60,000 ($105,000 - $10,000 - $5,000 - $16,000 - $14,000 = $60,000). You could have up to $5,100 of long-term capital gains and/or dividends this year without owing the IRS a dime. Why? Because your total taxable income, including the gains and dividends, will still be no more than $65,100 and within the 15% rate bracket. You might have to pay state income tax on those gains and dividends, but you're free and clear when it comes to federal income tax. Any additional 2008 long-term gains or dividends would be taxed at the maximum federal rate of 15%, which is still pretty low.
