It is possible to claim a $3,300 exemption for each of the following, provided you are not subject to the phaseout of exemptions for high income taxpayers:

• Yourself. You claim an exemption for yourself unless you are the dependent of another taxpayer. If someone else can claim you as a dependent for 2006, you may not claim a personal exemption for yourself on your own return; this is true even if the other person does not actually claim you as a dependent. This rule prevents your child or other dependent from claiming an exemption on his or her return if you may claim an exemption for the child or other dependent.
• Your spouse. You claim your spouse as an exemption when you file a joint return. If you file a separate return, you claim your spouse as an exemption if he or she has no income and is not a dependent of another person.
• Your dependents. There are two categories of dependents: qualifying children and qualifying relatives. You may not claim any dependents if you can be claimed as a dependent by another taxpayer. In addition, a qualifying child or relative must meet a citizen or resident test, and, if married, must generally not file a joint return; see below.

In other words:

• you may claim yourself, your husband/wife , and your dependents
• If a dependent who otherwise met the tests for a qualifying child or relative died during the year, you can claim an exemption for that person.
• !!You can claim an additional exemption of $500 for each person who was displaced by Hurricane Katrina!!
