How much money will PayPal report to the IRS?

PayPal may report qualifying business or commercial payments to the IRS based on current tax reporting rules. There is not a single universal number for all users because reporting depends on how the account is used and what thresholds apply that year. Personal payments generally are not reported the same way as business income. If you sell goods or services through PayPal, you should assume records may be reported if thresholds are met. The app itself is not the issue; taxable income is. To stay safe, keep clean records and separate personal activity from business activity. If the payment is income, report it even if no tax form arrives immediately.
