Do I need to pay taxes on Cash App?

You do not pay taxes simply because you use Cash App. Taxes depend on what the money represents. Personal transfers, gifts, reimbursements, and splitting expenses are generally not taxable income. Money earned from work, sales, or services is usually taxable and should be reported according to tax rules. If Cash App is used for your business, you should treat it like any other payment processor and keep records. The app does not create the tax liability; the underlying income does. Good bookkeeping is the easiest way to stay compliant and avoid confusion later.
