Gyms and fitness centres look straightforward from the outside — people pay for memberships, they work out. In practice, the bookkeeping involves deferred income recognition, contractor floor-fee arrangements, complex equipment finance structures, mixed-GST revenue streams, and a persistent bad-debt problem created by failed direct debit payments. Every one of those areas can generate a material misstatement if handled incorrectly.
Membership Income: Timing and Deferred Revenue
Monthly direct debit arrangements are the dominant membership model for Australian gyms. A member's account is debited on, say, the 1st of each month and the gym earns that revenue as the month progresses. At month-end, amounts received but not yet earned (for example, the final three days of a billing cycle that straddles two months) should be held in a deferred income liability, not immediately recognised as income.
Annual memberships paid upfront create a larger deferred income balance. Under AASB 15 (Revenue from Contracts with Customers), the performance obligation is the right to access the facility over the membership term. Revenue must be recognised ratably over that term — one-twelfth per month for an annual plan. A gym that books the full annual fee as income in the month of receipt overstates income in the first month and understates it in every subsequent month.
Practical bookkeeping setup: create a "Membership Fees in Advance" liability account. Each month, process a journal to move the earned portion from the liability to the revenue account. At BAS time, GST on membership income is recognised when earned, not when received, unless the gym is on a cash basis for BAS.
Personal Trainer Contractors and the Floor Fee Model
Many gyms engage personal trainers as independent contractors under a floor-fee arrangement: the PT pays the gym a weekly or monthly room-hire fee for the right to operate from the premises, and then bills their own clients directly for PT sessions.
For the gym, the floor fee is assessable income — a taxable supply on which the gym charges GST. The gym is not employing the PT; it is renting access to its facility.
However, the independent contractor classification must withstand scrutiny against the ATO's multi-factor tests: whether the PT can subcontract, whether they provide their own equipment, whether they bear the risk of poor results, and whether they work for multiple clients. A PT who works exclusively at one gym, follows the gym's schedule, and uses gym-owned equipment looks a great deal more like an employee. If re-classified as an employee, the gym is liable for PAYG withholding, superannuation guarantee contributions, and payroll tax (above the relevant state threshold).
Where the gym sells PT session packages itself and then pays PTs for delivering those sessions, the employment character of the arrangement is even stronger. These arrangements should be reviewed against the contractor versus employee tests before treating PT payments as contractor invoices.
Equipment Finance: Chattel Mortgage and Hire Purchase
Commercial gym equipment — treadmills, weight racks, cable machines, cardio equipment — typically costs tens of thousands of dollars and is almost always financed. The two most common structures are chattel mortgage and hire purchase.
Under a chattel mortgage, the gym takes ownership of the equipment at acquisition. The full GST on the purchase price is claimable immediately (in the BAS period of acquisition). For SBE-eligible operators, the full cost of the asset (up to the instant asset write-off threshold, $20,000 for 2024-25 for small business entities) is deductible in the year of purchase. The loan appears on the balance sheet as a liability; interest is deductible as incurred.
Under a hire purchase, the finance company retains title and the gym acquires the equipment at the end of the term. For accounting purposes, the gym recognises a right-of-use asset and a corresponding liability under AASB 16. Interest is recognised over the lease term using the effective interest method. GST under a hire purchase is typically spread across the payments rather than claimable upfront — confirm the treatment with the finance documents.
Maintain a separate fixed-asset register for each piece of commercial equipment, noting acquisition date, cost, finance structure, accumulated depreciation, and effective life (ATO Table B: exercise equipment, 10 years for commercial grade).
GST on Memberships, Training and Café Revenue
Gym memberships are taxable supplies — there is no GST-free health services exemption for gymnasium memberships. The ATO's GSTR 2002/3 confirms that a general right to use a gymnasium facility is not a health service under s.38-7 of the GST Act. Membership fees, casual visit fees, and personal training sessions delivered by the gym (or its employees) are all taxable.
Many gyms operate a café, smoothie bar, or supplement retail outlet. These represent separate revenue streams with distinct GST profiles:
- Protein powders and sports supplements are taxable supplies (they are not "food" as defined in s.38-4 GST Act).
- Whole food café items (sandwiches, fruit) may be GST-free.
- Bottled water and juices can be GST-free; energy drinks are taxable.
- Pre-packaged items sold at retail (protein bars with added ingredients not ordinarily consumed as a food) are taxable.
Separate revenue accounts for membership, PT, café, and retail ensure the BAS is correctly populated and GST reporting is accurate at line level.
The Delinquent Member Problem: Failed Direct Debits and Bad Debts
Gym direct debit failure rates of 5–15% are common. When a direct debit fails, the gym attempts re-presentation and then may refer the debt to a collection agency or write it off. Failed debits create a receivable on the balance sheet that, if left uncleaned, accumulates into a material overstatement of assets.
A gym on accruals accounting will have recognised GST on those invoiced amounts. When a debt becomes genuinely bad and is formally written off, a GST adjustment is available under Division 21 of the GST Act. The gym can reduce its net GST liability by 1/11th of the written-off amount, reported at label G18 on the BAS in the period of write-off.
The ATO's TR 92/18 sets the standard for what constitutes a bad debt: the gym must have taken reasonable recovery steps, further action must not be expected to result in payment, and the debt must be formally written off in the accounts (not merely provisioned). A board or management-level write-off authorisation document is good practice. If a written-off debt is subsequently recovered (the member catches up on a payment plan), the recovery amount is assessable income in the period of receipt, and the GST adjustment is reversed at label G15 of the BAS.
Separating Personal and Business Finances for Owner-Operated Gyms
Owner-operated single-site gyms are frequently structured as a company or family trust, but the operator often blurs the line between personal and business expenditure — gym gear, nutrition products, and travel to industry events can all be dual-purpose. For tax purposes, the deductible portion of a mixed expense is only that which relates to producing assessable income. Where an owner uses the gym's equipment personally, there may be an FBT implication (a property fringe benefit) if the facility is also available to the owner outside the ordinary course of business.
A clearly defined chart of accounts, a consistent expense classification policy, and monthly bank reconciliation through a tool like ReconLink ensure that membership income, PT floor fees, café takings, and equipment finance costs are tracked separately — giving both the bookkeeper and the tax agent an accurate picture when BAS lodgement and year-end compliance fall due.
