Is W2 and Tax Return BOTH required for Parents visa interview?

Hi,
I am slightly confused about the requirement of W2 Vs Tax Return for the visa interview of my parents. Are both the W2 and Tax Return required or only having W2 is enough? Please advice asap. Thanks very much in advance.

Regards,

There is nothing mandatory from sponsor's side other than I-134. It is up to you what you would like to provide. More documents you provide, better it is.
