This ranking covers accounting firms in Sydney, including chartered practices, tax specialists and bookkeepers who work in cloud software. TrustList lists 91 of them, and 21 earned a rank number in the Q4 2026 edition. Of those 21, two hold a professional accreditation and 20 state a founding date, from the 1910s to the 2010s, with the 2000s the most common decade. Nine give Sydney as their base, two the Sydney CBD, and the rest name areas such as Norwest Business Park, the Northern Beaches, Roseville, Kirrawee and Bankstown.
The order rests on the evidence TrustList held on 5 October 2026: client reviews, vetting, awards, and facts each business states on its own website, which we read and dated. Nobody pays to be placed. Listings with nothing checkable are listed but not ranked, and positions stay fixed until the January 2027 edition. A business can move up by adding client reviews or verified facts to its free profile.
