Most accountants are reactive.

They lodge your return, send an invoice, and disappear until next year.

Meanwhile, missed deductions, structural issues, and opportunities your accountant never raised quietly cost you money, and you find out about your tax bill when it's too late to do anything about it.

We work the other way around. We forecast, plan, and check in with you every quarter, so tax is managed all year, not just at lodgement time.

Three steps, starting with one free call.

01
The Conversation
We get to know your business, your goals, and where tax is causing you stress.
02
The Deep Dive
We review your most recent tax return, your entity structure, and your current financials. We're looking for missed deductions, structural issues, and quick wins that can reduce your tax position right away.
03
The Game Plan
You get a clear report showing what's working, what's costing you, and exactly what we'd change. Plus a proposal with quarterly check-ins built in, so your tax is managed year-round, not just when your accountant gets around to doing your tax.

It all starts with a free 30-minute conversation. Book it below.


Book your free 30-minute Tax Structure Review.

Answer a few quick questions so we can prepare for your call.

Step 1 of 5

What’s your biggest challenge right now?
What are your annual sales?
What kind of business do you run?
When was the last completed tax return for your business?
Where do we send your confirmation?

We’d love to chat.

We’re probably not the right fit right now.

Thanks for filling that out. What we do is built for businesses turning over more than $250k a year. It’s a fair bit more involved than what a business your size normally needs, and you’d be paying for things you won’t use yet. We’d rather be upfront about that now.

If that changes down the track, or you’re looking at your structure and want a second set of eyes on it, get in touch, thank you.

Your answers and contact details go into our practice systems so we can prepare for your review and contact you about our services. We never sell or share them. Privacy policy.

Justin and the team at F5 Accountants have been fantastic to deal with. They look after the accounting for my family, my development business, and several friends I’ve referred to them. Professional, reliable and always easy to communicate with. Highly recommend Justin and F5 Accountants.

Couldn’t recommend F5 Accountants highly enough! The team are always friendly, approachable and genuinely helpful. They make everything really easy to understand, are always happy to answer questions and take the stress out of anything accounting related. Communication has always been great and nothing ever feels like too much trouble. It’s nice dealing with people who are professional but still down to earth and easy to talk to. A special shout-out to Josh and Justin as well for all of their hard work, support and advice. It’s always greatly appreciated and definitely doesn’t go unnoticed! Would definitely recommend the F5 team to anyone looking for a reliable and knowledgeable accountant.

F5 Accountants did a great job sorting out my tax return this year. It was a pretty complicated one with a lot of moving parts, but Josh was super helpful and easy to deal with. He actually knows his stuff and made the whole process painless. Definitely recommend them if you want an accountant who just gets it done right.

From my very first conversation with Josh, I immediately understood I was dealing with true professionals. The entire team at F5 Accountants is incredibly knowledgeable and consistently up to speed. Whether you’re speaking with the assistant, an accountant, or the director, everyone knows exactly what’s going on and supports you from every angle. They do what they say they will do. They’re reliable, clear, and factual, and they focus on making sure your tax is handled properly and efficiently. I’ve always felt taken seriously and looked after, regardless of my situation. From day one, I never felt like “just a customer”. They genuinely care and assist you to the best of their abilities. F5 Accountants deliver on professionalism, trust, and service, and I couldn’t recommend them highly enough.

Could not rate Justin and the team at F5 high enough. We had a terrible experience with our previous accountant, having to pay a huge amount in tax from a period where we lived overseas. The next tax year we were recommended the F5 team and at first glance Justin said our recent payment and returns didn’t look right, asking if he could investigate. He did and he was correct, we had been give really bad advice and all the money was returned. Justin was so lovely and it was such an unexpected outcome. The team are super knowledgeable and easy to talk to. High recommend.

“Business owners deserve more than a tax return once a year and a bill in the mail.”

Founder & CEO · F5 Accountants

I started F5 Accountants because business owners deserve more than a tax return once a year and a bill in the mail.

I'm a Chartered Accountant and Registered Tax Agent, and I've been nominated for awards in the industry. But what I'm most proud of is that my clients actually enjoy working with their accountant, probably for the first time.

We're a small team by design. I'd rather work closely with fewer clients and deliver real results than spread my team thin giving everyone the same service.

If you're ready for an accountant who knows your business inside and out, book a free Tax Structure Review and let's chat.

Frequently asked questions.

Here's what we usually get asked.

It starts with a 30-minute conversation (book from the form above). From there, our team does a deep dive into your most recent return, your structure, and your financials. Then we come back to you with a clear game plan: what we found, what we'd change, and how we work together going forward.

Once you decide to move forward, we take care of the paperwork and the hand-over so you don't have to manage it. The whole thing is usually sorted within 1 to 2 weeks.

That's why we start with a detailed review of your past returns and current structure. We look for missed deductions, incorrect entity setups, and opportunities to amend prior lodgements where the ATO allows it. Our clients regularly find savings they didn't know were available, often from things their previous accountant simply never raised.

We explain everything in plain English, not jargon. Our clients tell us we're the first accountant who actually made them feel comfortable asking questions. There's no such thing as a stupid question here.

Every client has different needs and different things they want from us, so we don't have a one-size-fits-all price. On the review call we'll get a clear picture of your situation and give you a transparent, fixed-fee quote. No surprises, no hidden charges. You'll know exactly what you're paying and what you're getting before we start.

We see it all the time, and we can help. Whether it's a shoebox of receipts or a Xero file that hasn't been touched in months, we'll get you sorted. We can clean it up, set you up properly on Xero, and keep it maintained going forward.

No. We're an online accounting firm and we work with clients all over Australia. Client meetings happen virtually, so location is not an issue.
