Does the IRS know if you have a Venmo account?

The IRS may not automatically know every detail of your Venmo account, but it can receive reported information in some cases. Venmo and similar platforms may send tax forms for qualifying business or commercial activity. In addition, transaction records may be accessible through audits, subpoenas, or bank and platform reporting requirements. Having an account itself is not the issue; taxable activity is. If you only use Venmo for personal transfers, that is usually not a taxable event. If you use it for business income, you should assume the activity may be visible and report it accurately.
