In general, you may claim an exemption for your child on your tax return if you are the custodial parent following a divorce or separation. Form 8332 is one way for the custodial parent to transfer the tax exemption to the other parent. Instead of using this form, you may use a similar statement containing the same information as on the form.
The noncustodial parent claims the exemption by attaching Form 8332 (or a similar statement) to his or her tax return. Note, however, that the parent claiming the exemption must meet all the other requirements for the claim (relationship, marital status, citizen or resident, and income). See IRS Publication 504 for details.
If the custodial parent completes Part II (Release for Future Years), the noncustodial parent must attach a copy of the Form 8332 each year that the exemption is claimed.
