About

A Sydney practice since 1974.

Tsia Partners is a Sydney chartered accounting and tax practice working with individuals and businesses across Australia. We handle the annual compliance work and advise on the decisions around it. We have kept the practice small so a principal stays responsible for your work.

Many clients have been with us for decades, through business sales, family changes and the occasional ATO review.

Our history

The practice began in 1974 as L K Tsia Chartered Accountants, founded by Loi Kah Tsia. Tsia Partners was formed in 2019 to continue that work, led by Jia Hao Tsia.

Founder

Loi Kah Tsia

Known to clients as Tom
BComm, FCA, FCPA — Tax Agent and Registered Auditor

Tom was born in Sandakan, Sabah, in 1947. He grew up in Malaysia and came to Australia on his own to study. After qualifying as a Chartered Accountant he worked in other firms for several years, and in 1974, with the support of his wife, he opened his own practice, L K Tsia Chartered Accountants, in Sydney.

Over more than forty-five years he advised charities, unions and employer associations, manufacturers, family businesses and individuals. Many of those clients are still with the practice today.

He worked to three principles, and Tsia Partners still does:

Client first
Honesty
Responsibility

The firm is now led by Jia Hao Tsia.
