You can theoretically send money to yourself if you have two distinct Cash App accounts. You might send money to yourself directly from your account. You can send money right now to your other Cashtag or email account.
Can you Transfer Money to your self on Cash App between two of my own payment methods or pay myself using Cash App? You can, but Cash App is only meant to be used for payments between different people, not for transferring cash between your own payment methods.
