About Optium Accountants
Optium Accountants is a CPA-qualified accounting firm based in Clifton Hill, Melbourne. We provide tax returns, BAS lodgement, SMSF accounting, small business bookkeeping, and business advisory services for individuals and businesses across Australia — in person and online since 2007.
Our Story
Optium Accountants was founded with a straightforward purpose: to give everyday Australians and small business owners access to professional-grade accounting and tax services at fair, transparent prices — without the excessive fees or impersonal service that larger firms often deliver.
We launched our online tax return service in 2007, well before remote accounting became mainstream, and established our Clifton Hill office in 2018. Today, our team of five serves individual taxpayers, sole traders, partnerships, companies, trusts, SMSFs, and non-profit organisations across Australia.
Our approach is deliberately different from reactive compliance-only firms. We plan for next year's tax position while managing this year's affairs — finding legitimate savings early, avoiding surprises at year-end, and delivering genuine strategic value to every client relationship.

What Makes Us Different
Proactive, not reactive
We plan for next year's tax position during this year — not just after EOFY. Clients receive proactive advice throughout the year, not just at lodgement time.
Extended lodgement dates
As registered tax agents and BAS agents, we secure extended ATO lodgement and payment deadlines for all client return categories — reducing stress and penalties.
Plain English communication
We explain tax and accounting in language our clients actually understand — no jargon, no confusion. Transparency is non-negotiable.
Transparent fixed fees
We quote a fixed fee upfront, scoped clearly to avoid bill shock. No scope creep, no hidden charges.
Minimal staff turnover
Clients deal with the same team members year after year — building deep familiarity with their situation and reducing the need to re-explain their history.
Fast turnaround
Individual tax returns are typically completed within a few hours. Business tax returns are completed within about one business day.
