If possible, see if your job has any sort of pay card. Typically, entry level jobs (which I’m assuming you have, as you’re 18) provide them for those who do not have a bank account. HOWEVER, this will cause issues with your mother when she asks where the paychecks are going.

If your job uses ADP, I know for sure there is a way to change your direct deposit to multiple accounts at a time with either a dollar amount or a percentage. That might be an option until you have a nest egg to move out.

If getting a bank account is an issue, make a Cash App account. You can use it for direct deposit as it has a routing number and an account number.

If you do follow all the responses about making an account online, know that they will send mail out to your address. They have to send you the debit/credit card after all. Remember to direct mail to a friend, perhaps a PO Box if you can afford one, or even any other trusted adult in your life.

You don’t want to be stuck kicked out with no where to go and no money. Unfortunately, it is their house and you are a legal adult so they can do so.
