Why every gym owner should consider tax calculation before setting membership fees

Taxes are facts of life, and miscalculating them can make your membership pricing fall apart.

A new gym owner starts out with a dream. A dream to build a place where people get stronger, healthier, and happier. But forgetting taxes can break this dream faster than a dumbbell falling onto your toe. 

So what is the right way to tax? We’ve taken two examples to show you the right way and the wrong way to go about it.

Mr Wrong set up his gym and made 10 big mistakes. Let’s look at what they are.

How taxes sneak into your membership pricing

Many gym owners think: “I’ll just set a price that feels right, cover my costs, and watch the profit roll in.” Wrong. What they forget is that taxes are not optional; they eat into every membership payment you collect.

Failing to calculate them upfront, and suddenly your pricing model is upside down:

• Your “profit” shrinks before you even see it.
• You undercharge members without realising it.
• And when tax bills arrive, you’re scrambling to pay instead of planning to grow.

In short, taxes don’t just affect compliance; they shape your membership fees, profit margins, and peace of mind.

10 rookie tax mistakes that wreck membership fees

Here’s where most gym owners slip up, and yes, every mistake eventually seeps into how you price your memberships:

1. Forgetting sales tax/VAT – Charge $100/month without tax planning, and after VAT/GST, your take-home might be closer to $85.
2. Mixing personal and business funds – A tax nightmare that makes tracking gym income (like memberships) impossible.
3. Guessing deductions – Over- or under-claiming costs like equipment can skew how you set fees.
4. Ignoring payroll taxes – Trainer salaries aren’t just salaries; they carry employer tax burdens you must price into memberships.
5. Not accounting for local levies – City taxes, permits, or fitness-specific fees creep in.
6. Cash-only mindsets – No proper invoicing? You can’t track income or justify membership pricing strategies.
7. Skipping quarterly tax planning – Wait until year-end, and you’ll find your membership revenue model doesn’t hold up.
8. Copying competitors’ fees blindly – Their prices might not include proper tax planning; why repeat their mistake?
9. Forgetting tax on retail sales – Selling supplements, merch, or drinks? That’s taxable income tied to memberships.
10. Not using software: Manual spreadsheets lead to errors that misalign fees with actual profit.

Bottom line? Tax mistakes don’t just hurt compliance; they undercut the very foundation of your membership fee structure.

James vs. Tom: A Tale of Two Gym Owners

Let’s make this real with two gym owners who took very different approaches.

James: The Passionate Planner

James sets a simple but firm goal: he wants to take home $15,000 after taxes by the end of the year. To get there, he works backwards.

With a 20% income tax rate, James knows he needs a pre-tax profit of $18,750. His yearly expenses add up to $45,000. On top of that, the state requires him to collect sales tax, money that passes through his account but never belongs to him.

So his total revenue must cover three things:
Expenses + Pre-tax Profit + Sales Tax.

James does the math with 100 members in mind. To reach his goal, he charges $68.75 per member each month before tax. With a 6.25% sales tax added, each member pays $73.04 per month.

At the end of the year, James collects the sales tax and remits it to the state, pays 20% income tax on his $18,750 profit, and takes home exactly $15,000, just as planned.

Because James built taxes into his pricing from day one, he hits his target with no surprises. His system is solid, and his business feels steady.

Tom: The Well-Meaning but Unprepared Owner

Tom also wants his gym to succeed, but he doesn’t plan as carefully. Instead of working backwards, he picks a number that “feels right” and charges $59 per member per month, without thinking about sales tax.

With 100 members, Tom’s yearly revenue looks like $70,800. After subtracting his $45,000 in expenses, he assumes he has a profit of $25,800.

But here’s the catch: Tom forgot that sales tax must come out of his pocket. On $70,800 in revenue, he owes the state $4,425 in sales tax. That leaves him with an actual pre-tax profit of $21,375. After paying 20% income tax (another $4,275), his real take-home drops to $17,100.

At first glance, Tom takes home more than James. But his numbers are shaky. Since he never accounted for sales tax, a small rise in expenses or a dip in membership could slash his earnings much faster. His pricing leaves no cushion, no predictability, and no peace of mind.

James vs. Tom

Item	James (Tax-aware)	Tom (Tax-unaware)
Monthly fee (before tax)	$68.75	$59.00
Monthly member pays (incl. tax)	$73.04	$59.00
Annual revenue (incl. tax)	$87,648	$70,800
Sales tax collected/owed	$4,898	$4,425
Revenue after sales tax	$82,750	$66,375
Expenses	$45,000	$45,000
Profit before income tax	$18,750	$21,375
Income tax (20%)	$3,750	$4,275
Final take-home profit	$15,000	$17,100

Tax-smart membership pricing: how to do it right

So, how can you avoid Tom’s mistakes and act more like James?

1. Start with after-tax profit goals
   Ask yourself: “How much do I want to take home each month?” Then work backwards by adding expected taxes and costs.
2. Research local tax rates
   VAT, GST, or city-specific fitness levies all impact the membership fees you need to charge.
3. Include payroll & operations
   Trainer salaries, utility bills, and equipment maintenance all feed into your pricing model. Don’t ignore their tax load.
4. Plan quarterly, not annually
   Quarterly reviews keep your fees aligned with changing tax rates or new laws.
5. Use gym management software
   Manual spreadsheets? Too risky. Smart software calculates taxes automatically, keeps your pricing transparent, and ensures compliance, without draining your time.

Why this isn’t just about compliance

Some gym owners treat tax planning like a box to tick. Big mistake.

This is about:

• Profit margins – Protecting what’s yours.
• Growth potential – Pricing fees that fund expansion, not just survival.
• Peace of mind – No nasty surprises come tax season.

Tax-aware pricing is not just smart, it’s the difference between thriving and barely surviving.

Don’t let taxes weigh you down

So, why should every gym owner consider tax calculation before setting membership fees?

Because your fees don’t just represent a number on a flyer, they’re the heartbeat of your business model. Taxes eat into them silently, but only if you let them.

Plan like James, and you’ll build a gym that grows strong, stays compliant, and keeps you financially fit. Ignore it like Tom, and your gym will always feel like it’s running out of breath.
