Deliberately Keeping Your Income Under $75k to Avoid Having to Deal with GST? You Might Want to Rethink That

“Better not earn too much or I’ll have to register for GST!”
Sound familiar?
It’s a common practice in the massage therapy world: keeping your income under $75,000 so you don’t have to register for GST.
If you’ve ever slowed down your bookings, kept prices low, or avoided marketing just to stay under the threshold, you’re not alone. But here’s the kicker: that strategy might be costing you more than you think, and not just financially.
Avoiding GST obligations makes sense to many sole trader massage therapists: you avoid another tiresome registration process; you don’t have to modify your invoicing and accounting systems to add GST to client invoices; you don’t have to separate GST out of purchases and expenses; and you don’t have to lodge that quarterly – or worse, monthly — BAS. And you don’t have to spread yourself even thinner to allocate precious time and energy to these things.
But is it actually a good strategy for your business long-term?
Let’s take a look, from both a numbers and a mindset perspective.

If you think it’s not worth the effort, you’d be right… at $75k
Let’s say your annual revenue is $75,000 and then pretend that GST registration is voluntary.
Annual Revenue $75,000, Not Registered for GST
Assuming 20% of that revenue goes to business expenses, here’s how the numbers stack up:
- Income: $75,000
- Expenses: $15,000 ($75,000 Revenue x 20%)
Side note: When you’re not registered for GST, the expense amount you claim on your income tax return includes the GST. But you don’t get the full GST amount back – it just reduces your taxable income and therefore the amount of income tax you have to pay.
- Profit before tax: $60,000 ($75,000 Revenue – $15,000 Expenses)
- Income tax + Medicare Levy (approx): $ 9,988 (see the MoneySmart income tax calculator here for more detail)
- After-tax profit: $50,012
Apart from the conniption you might have due to the realisation that the grubbyment is making out like a bandit with ten grand of your money, it’s straightforward. Maybe the ATO puts you on its PAYG system and you prepay what it estimates will be next year’s bill in quarterly instalments. (I hope you’re setting that money aside throughout the year in preparation for that income tax bill. Too many therapists aren’t!).
Annual Revenue $75,000, Registered for GST
Assuming again that business expenses are 20% of business revenue and include GST, here’s what happens this time:
BAS return:
- GST collected: $7,500.00 ($75,000 Revenue x 10%)
- GST paid (claimable): $1,363.64 ($15,000 Expenses divided by 1.1, unless your receipts include GST-free or non-GST items).
Note: If you suck at maths and thought it should be divided by 10 here, then no. When a price includes GST, that means:
- 10 parts = the original price
- 1 part = the GST
- Total = 11 parts
So, we divide by 11 to get that one part, the GST.
- Net GST payable to ATO: $6,136.36
Income Tax Return:
- Profit before tax: $61,364 ($75,000 Revenue – Expenses without GST, i.e. ($15,000 Expenses – $1,363.64 already claimed on BAS)
- Income tax + Medicare Levy (approx): $10,424 (see the MoneySmart income tax calculator here for more detail)
- After-tax profit: $ 50,940
Here it is side by side if that makes it easier to process it:

Comparison: GST Registered vs Not Registered (at $75k Revenue)
So, you’re $928 better off by registering for GST. The reason for that is that you can claim the full GST amount on business expenses, rather than just your income tax rate percentage of it.
If you’re now thinking, I’m not going through all that rigmarole just for a lousy $928, I don’t blame you!
What if you earned more?
What if you were to let your income go higher and just surrender to the whole GST thing?
Here’s what happens if your revenue is $100,000 and you collect another $10,000 on top of that by adding 10% GST to your client invoices (You’re not earning this money because it’s not your income, you’re just collecting a tax on behalf of the grubbyment (congratulations on your new unpaid job as a tax collector):

You earn $100,000 + $10,000 GST
So your clients pay you $110,000 total
You spend $20,000 total on business stuff (which, again, includes GST)
What happens:
GST (handled in your BAS):
- You collected $10,000 GST from your clients on behalf of the ATO
- You paid $1,818.18 GST to suppliers (the GST included in your $20,000 expenses, or $20,000 / 11)
- You give the ATO the difference: $8,182.82 ($10,000 GST Collected – $1,818.18 GST Paid)
Income Tax (handled in your tax return):
- Income: $100,000
- Expenses: $18,181.82 ($20,000 Expenses – $1,818.18 GST already claimed on your BAS)
- Profit before tax: $81,818
- Income tax + Medicare Levy (approx): $16,970 (see the MoneySmart income tax calculator here for more detail)
- After-tax profit: $64,848
Which is a $14,836 reward ($64,848 after-tax profit less $50,012 after tax profit) per year for getting over your fear of the whole GST thing.
Here’s the $75k “Avoid the GST thing at all costs” vs the $100k “GST-Schmee-ST, I’d rather make more money” scenarios side by side if that makes it easier to process:
Comparison: Not Registered vs Registered for GST (with $100k Revenue + GST)

Honey, that’s enough to pay a registered BAS agent to do your books every month and prepare your BAS every quarter, and go on a damn good holiday each year (assuming your bookkeeping is reasonably straightforward and they don’t have to wade through a decade’s worth of “shoebox accounting”).
If you need to know more about what bookkeepers charge, here’s a good article about it.
And if you have a simple sole trader business, GST and BAS really aren’t that hard once you get the hang of it and set up your systems for it. You might even be able to do it all yourself and have an even better holiday!
$50k after tax profit isn’t the same as a $50k take home pay from a job
Okay, so you’re taking home $50k after tax. But that’s not the same as a $50k take home pay from a job.
A $50k employee salary comes with:
- Paid holidays
- Sick leave
- Super
- Worker’s comp
- Maybe even bonuses, training, or overtime.
But $50k as a sole trader? That’s all on you. No holidays. No super. No safety net. Just your two hands, your body, and the hope you don’t get injured or burnt out.
The GST threshold hasn’t changed since 2007
The final thing I want to say with my accountant’s hat on is that the GST threshold of $75k hasn’t changed since 2007. It was raised to that from the initial threshold of $50k. It’s not indexed to inflation: if it was, it’d be around $120,000 by now.

So, with the inflationary effects of money, deliberately keeping your income under the GST threshold year after year means you’re effectively giving yourself a pay cut every year.
Dude. Your boss sucks.
I’ve written another article about the effect of inflation on your income here.
The money coach’s two cents: how staying under $75k hurts you
Ok that’s the accountant’s argument for getting over your aversion to the whole GST thing. Now let me put on my money coach hat and give you some more things to consider if you’re deliberately keeping your income under $75k just to avoid the GST system.
1. You’re capping your income — on purpose
You start making real money, and instead of riding that wave, you pump the brakes. Why? Because you’re afraid of the paperwork. That’s self-sabotage disguised as “smart business”.
2. You’re not just avoiding admin, you’re avoiding growth
Staying under the threshold usually means:
- Not marketing harder
- Not raising prices
- Not booking out
You shrink your own business so you don’t have to deal with GST. That’s not business strategy, that’s fear management.
3. You’re wasting time managing your limits instead of your potential
Every time you eye your calendar or Stripe account thinking, “Better slow down or I’ll go over,” you’re wasting brainpower that could be spent building better systems, services, or pricing.
4. You’re locking yourself out of legit opportunities
Want to subcontract? Land corporate wellness or sports organisation clients? Apply for grants? Collaborate with allied health providers? They’ll want you GST-registered. Playing small isn’t just about the money, it limits your career options.
And let’s not forget all those government grants you missed out on during the height of the COVID pandemic because you weren’t registered for GST.
5. It builds a subconscious glass ceiling
The longer you stay under, the scarier it seems to go over. The resistance builds. You start believing that $75k is your limit.
Here’s a question for you:
Would you still be keeping your income under $75k if you weren’t dodging GST?
Probably not. And if the answer is no – if your business would naturally grow past that threshold – then dodging GST isn’t protecting your business, it’s stunting it.
The fear of losing clients by charging more
Now, if you’re thinking,
“But I can’t raise my prices — I’ll lose clients!”
You might be right. But here’s the thing: if your clients drop off the second you raise prices, they were probably never in it for the long haul anyway. And, chances are, you’re undercharging for your skill, your presence, and the work you do.
There are clients out there who will happily pay more and they’re often the ones who respect your boundaries, show up on time, and re-book without flinching.
So, ask yourself honestly:
Am I really protecting your business by avoiding GST or am I just holding it back?
Don’t let the tax man stand between you and your potential
If you’ve been treating $75k like a glass ceiling because of GST, it might be time to get your Theracane out and smash it.
You can absolutely learn how to handle GST, or get help from someone who already knows how.
Either way, don’t let fear of paperwork keep you from growing into the business (and income) you’re capable of.
