old nil returns

my wife would like to use your service. Her scenario, she used to work up to 2009, then became a housewife till mid 2015 when she started working again. Before, she never earned enough to file tax returns (dunno if that's still effective). She does have a tax number and would need to do her tax return this year. Se started working 1 July 2015. Would the lite or smart package be sufficient and is she most likely looking to have some penalties?

She would still need to file those old tax returns which she can do on TaxTim - she can make use of our blog on How to submit a nil tax return, but the lite package would be sufficient.
