Definitions

Recent tax legislation:The "Jobs and Growth Tax Relief Reconciliation Act" passed in 2003, and additional, related legislation in almost every year since, has included some significant, often temporary, and somewhat confusing changes. This is in addition to the already complex tax code changes passed by Congress in 2000. Below is a summary of the changes that impact most taxpayers in 2008.

  1. Child tax creditThe child tax credit has been increased from $600 to $1,000 through 2010. Starting in 2010, the tax credit returns to the level originally passed in the 2000 tax bill. The credit is, however, still phased out for higher incomes.

  2. Marriage penalty reliefThe new law makes the standard deduction for married couples filing jointly and qualified widowers to be double that of single tax filers. This puts the standard deduction for 2008 at $10,900. In addition to the increased standard deduction, the 15% tax bracket has been increased for married tax filers to further reduce the impact of the marriage penalty.

  3. 2008 Tax ratesBelow are the resulting tax rates and income ranges for 2008:

  1. Reduced Taxes on Capital Gains: Capital gains tax rates reduce to 0% and 15% respectively, for 2008. These capital gains rates are for property that was held for at least one year. This calculator assumes that all of your long-term capital gains are taxed the new rates of 0% and 15%.

  2. Reduced Taxes on Dividends: The new law applies the capital gains tax rates to qualified dividends paid from most U.S. corporations and certain qualified foreign corporations. This calculator assumes that all dividends are qualified, however, you should make certain that this is the case in your particular circumstance. All qualified dividends will appear in column 1b of Form 1099-DIV, which should be sent to you in January of the year following the dividend payment. Taxpayers in the 10% or 15% bracket pay 0% percent in 2008. Taxpayers in tax brackets above 15%, pay a 15% rate of tax on dividends paid between January 1, 2003, and December 31, 2008.

  3. IRA and retirement plan deductions: The new tax law did not change IRA deduction and contribution limits. However, the 2000 tax code increased the amount for most individuals to $5,000 for 2008. Those age 50 and over can contribute $6,000.

Filing statusChoose your filing status. Your filing status determines the income levels for your federal tax bracket. It is also important for calculating your standard deduction, personal exemptions, and deduction phase out incomes. The table below summarizes the five possible filing status choices. It is important to understand that your marital status as of the last day of the year determines your filing status.

Filing Status for 2008
Married filing jointlyIf you are married, you are able to file a joint return with your spouse. If your spouse died during the tax year, you are still able to file a joint return for that year. You may also choose to file separately under the status "Married filing separately".
Qualified Widow(er)Generally, you qualify for this status if your spouse died during the previous tax year (not the current tax year) and you and your spouse filed a joint tax return in the year immediately prior to their death. You are also required to have at least one dependent child or step child whom which you are the primary provider.
SingleIf you are divorced, legally separated or unmarried as of the last day of the year you should use this status.
Head of householdThis is the status for unmarried individuals that pay for more than half of the cost to keep up a home. This home needs to be the main home for the income tax filer and at least one qualifying relative. You can also choose this status if you are married, but didn't live with your spouse at anytime during the last six months of the year. You also need to provide more than half of the cost to keep up your home and have at least one dependent child living with you.
Married filing separatelyIf you are married, you have the choice to file separate returns. The filing status for this option is "married filing separately".

DependentsA dependent is someone you support and for whom you can claim a dependency exemption. In 2008, each dependent you claim entitles you to receive a $3,500 reduction in your taxable income (see exemptions below). In 2008, each dependent under the age of 17 also receives a tax credit of $1000. The credit is, however, phased out for at higher incomes.
Total exemptions claimedEach exemption you claim reduces your taxable income by $3,500 for 2008. You receive an exemption for yourself, your spouse and one for each of your dependents.
Capital Gain or LossThis is the total capital gain you realized from the sale of assets. This calculator allows you to enter your total short-term capital gain for investments held less than one year and your total long-term gain for investments held at least one year. Any amount you enter as a short-term capital gain is taxed as normal income. Any amount you enter as a long-term capital gain is taxed as follows:

  • This calculator assumes that all of your long-term capital gains are taxed at either 0% or 15%.
  • The tax is 0% for the portion of your gain that would have been taxed at 15% or lower tax if it were a short-term gain.
  • The tax is 15% for any of your capital gain that would have been taxed at a rate higher than 15% if it were considered a short-term gain.
  • This calculator assumes that none of your long-term capital gains come from collectibles, section 1202 gains or un-recaptured 1250 gains. These types of capital gains are taxed at 28%, 28% and 25% respectively (unless your ordinary income tax bracket is a lower rate).
