tried below no luck

Get-VM  | Where { $_.PowerState –eq 'PoweredOn' } | Get-TagAssignment |where{$_.Tag -like ''} | Select @{N='VM';E={$_.Entity.Name}}

Try something like this

Get-VM |
where{$_.PowerState -eq 'PoweredOn' -and -not (Get-TagAssignment -Entity $_ | where{$_.Tag.Name -eq 'Tag1'})} |
Select Name
