Linden Lab Official:How do I view statements of my account activity in printable PDF form?

After you've logged into your Dashboard on secondlife.com, click the Account section on the left to expand it, then click the Account Statements link. You can download statements for every month of your account's existence, up to and including the last complete month (if you check in the middle of December 2008, you'll see November 2008 as the latest statement). These statements will be permanently available and can be downloaded as many times as you like. For Residents who need to claim Value Added Tax (VAT) back from their tax office, the Summary section of the statement groups all VAT charges into a single total; this serves as a summary of VAT invoices for each month.
