I have written a method below like this:

IList
JaredPar already provided the correct answer, I just wanted to suggest a simpler implementation of the method:
internal static IList GetEmpowerTaxViewsByLongAgencyAndAgencyTaxTypes(
IList validEmpowerCompanyTaxDatas,
IList empowerTaxViews)
{
var results =
from empowerCompanyTaxData in validEmpowerCompanyTaxDatas
from etv in GetEmpowerTaxViewsByLongAgencyAndTaxType(
empowerCompanyTaxData, empowerTaxViews)
select etv;
return results.ToList();
}
