CCH iKnow is the best resource I have seen for a concise summary of corona virus stimulus measures.
Kylie Parker
Thank you and a big shout out to to CCH iKnow for providing a detailed explanation every night of all the changes to #JobKeeper and other tax changes, as well as a weekly tax news summary email provided promptly each Friday. Taking services like this for granted can become easy, especially when you’re subscribing to them, but this resource is easily the best investment I make for my practice. Being regularly provided information about tax news and topics such as these keeps me informed, alert and current – which right now is the most important thing an accountant can be!

The powerful search function of CCH iKnow makes it easier and faster to find and share the exact content that you are looking for. With its very readable format our clients can see for themselves that the information straight from iKnow supports the advice we are giving them. We’re a CCH iFirm practice and the integration of the entire suite means it’s become second nature to include CCH iKnow in our advisory processes.

Product Excellence – As a corporate tax specialist, I have managed to solve two tax questions this afternoon alone relating to Duties and Fringe Benefits tax by using the Boolean search function and simply clicking into the right Practice Area. Having the search results categorised by Practice Area helps to enhance the efficiency of my research skills.
