parents visitor visa - tax return

[lata]

I came to USA in beginning of 2005, so my tax return has not been filed. I am sponsoring for my parents visitors visa.
I saw the website and it mentions that "written explanation why tax return was not filed" needs to be given. Is there a sample document for this?
Thanks & Regards,

Just say the same thing that you wrote here. As you came here only in 2005, you can't have any income tax returns yet.
