How custodial accounts work in Wisconsin
A custodial account lets an adult (the custodian) hold and manage investments, such as stock, for a child. The assets legally belong to the child, and the custodian must manage them for the child's benefit.
Under Wisconsin's Uniform Transfers to Minors Act (UTMA), the custodianship generally ends and the child takes full control at age 21. Older UGMA accounts in Wisconsin use the age of majority, 18.
Extension rules: Wisconsin does not list a special option to change the termination age; the default of 21 generally applies.
SpaceX pledge
What this could mean for a SpaceX share in Wisconsin
SpaceX and Elon Musk have not announced how shares would be delivered to children. If a share were placed in a custodial account, Wisconsin's rules above would typically decide when your child could control or sell it.
There is currently no official sign-up. Don't share your child's Social Security number or pay anyone to "claim" a share. Track official updates on our Latest News page.
Taxes
Taxes and financial aid
- Investment income in a child's name may be subject to the federal "kiddie tax".
- Wisconsin state income tax rules may also apply — check with the state's tax agency or a tax professional.
- Custodial accounts are counted as the student's asset on federal financial aid forms, which can affect aid eligibility more than parent-owned savings.
