An 8332 can be filled out for more than one year. Otherwise, it needs to be a new form each year.
All that’s needed is
your child's name, the tax year, your Social Security number, then the custodial parent signature and date. If you prefer to get release of claim to your child's
exemption for more than one tax year, enter the same information in part two rather
than part one.
Once complete, file
it with your tax return. If they release claim for multiple tax years, you only
need to fill out the form once and attach copies of the original to your return
each year.
