The idea that you need to sit across a desk from your accountant to get quality advice is outdated. Here's why thousands of Australians now prefer online accounting services:
No geography limit
You are not restricted to accountants within driving distance. Access Melbourne-quality CPA expertise regardless of where you live in Australia.
Faster turnaround
Digital document exchange and cloud-based processing means returns are often completed faster than traditional firms — individual returns within hours.
Same legal standing
An online tax agent has identical legal authority to lodge returns as a face-to-face accountant. Registered tax agents and BAS agents are regulated by the Tax Practitioners Board regardless of delivery method.
Transparent pricing
No in-person consultation fees. Our flat web-rate pricing structure means you know the cost upfront — no time-billing surprises.
Extended ATO deadlines
Using a registered tax agent online gives you the same extended lodgement dates as any agent — no penalty for lodging through a remote firm.
All software supported
We work with Xero, QuickBooks, MYOB, Wave, and all other major Australian accounting platforms — wherever you are in the country.
Who We Serve Across Australia
Frequently Asked Questions — Online Tax Accountant
Is it safe to use an online tax accountant?
Yes — provided the accountant is a registered tax agent with the Tax Practitioners Board (TPB), which Optium Accountants is. Registered agents must hold professional indemnity insurance, meet ongoing education requirements, and comply with the Tax Agent Services Act. Document exchange is handled via secure encrypted channels.
How do I send my documents to an online accountant?
We accept documents via secure email, cloud storage links (Dropbox, Google Drive, OneDrive), or our client portal. We provide clear instructions on exactly what to send after your initial consultation.
Can an online accountant in Melbourne lodge my return if I live in Perth?
Absolutely. Australian tax returns and BAS lodgements are lodged electronically with the ATO regardless of where the accountant or client is located. There is no geographic restriction on which registered tax agent can lodge on your behalf.
What if I have questions during the process?
We are available by phone, email, and video call during business hours (Monday–Friday, 9am–5pm AEST). All queries are handled promptly — you are never left waiting weeks for a response.
