Unfortunately, PayPal doesn't send out tax invoices but if you follow the steps below you can get a statement to use for tax.
PayPal's Monthly Financial Summary provides you with a monthly snapshot of your PayPal account activity. This report consolidates fees, payments, chargebacks, and refunds, detailing your account transactions from beginning to ending balance.
Here's how to view your monthly financial summary report:
Log in to your PayPal account.
Hover on History and click on "Reports".
Click "Monthly financial summary."
Enter the month or date range you want to view and click "View Report."
Select what format you'd like to download your report in, and then click "Download.
The statement defaults to your primary currency. If you wish, you can select to view the statement for a different currency. For a list of descriptions for the different sections of the statement, click the 'Help with this page' link in the upper right-hand corner of the screen. You can download this report as a PDF, Excel, CSV, or TAB file.
