Kylie started with Callaghans as a starry eyed young undergraduate while still at university in 2001. Since that time, her enthusiasm for tax has not waned (do not invite her to dinner parties), and she is now well versed in all areas of Callaghans, most of which she has worked in at some stage over the years. Kylie became a partner of Callaghans in January 2017.
Kylie specialises in individual taxation including advice relating to investment properties, capital gains tax, salary packaging and estate planning.
She loves being able to work personally with clients and see the rewards of collaboration and tax effective planning come to fruition.
When not watching spreadsheet videos, Kylie spends her time with her adopted retired greyhound, on a volleyball court or finding great walk and coffee spots around the Canberra region.

Ruth qualified as a Chartered Accountant in 1987. After a career in auditing and a break to raise a family, she joined Callaghans in 2012. Progressing up the ladder, she is now Business Services Manager specialising in companies, partnerships and trusts with a few individuals and SMSFs thrown in.
As she is Scottish, she has a wicked sense of humour (Scots need it) and is a straight talker – no sugar coating.
For relaxation, she walks her two dogs and has sustained a number of injuries while doing so (broken tibia, broken nose and broken toe) – apparently not the dogs’ fault.
