I am looking for a high quality Australian company that does Business Tax Returns online. I have found 3 companies: www.taxspot.com.au , www.ezytaxonline.com.au& www.taxeazy.com.au . I want to know if anybody on this forum has ever used any of these three companies to do their business tax returns online and if they are any good? If not, what company would people recommend
