GST Registration Without Losing Part of Your Cleaning Price
Adjust cleaning prices when registering for GST so the tax is not quietly absorbed from the amount the business previously retained from each customer.
Key takeaways
- GST turnover is based on business income, not profit.
- A business generally needs to register once the A$75,000 threshold test is met and must act within the required timeframe.
- Adding 10% and extracting GST from an inclusive price are different calculations.
- Existing residential and commercial clients may respond differently to the change.
Registering for GST does not automatically damage a cleaning business's margin. Absorbing GST into an unchanged customer price can. If a A$100 non-GST price remains A$100 after registration, part of that amount is now collected for the ATO rather than retained as sales revenue. The pricing decision needs to be made before the first GST invoice is sent.
Confirm the registration position first
The ATO states that a business generally must register when GST turnover reaches A$75,000 or is expected to reach it under the current or projected turnover tests. Once required, registration is generally needed within 21 days.
Use current ATO guidance or professional advice. Do not wait until the annual tax return to ask whether the threshold was crossed months earlier.
What happens to a A$100 price?
Before registration
Customer pays A$100. No GST is included.
After registration, GST added on top
Customer pays A$110. The business records A$100 in sales and A$10 GST on the taxable sale.
After registration, customer price stays at A$100
The GST component of a GST-inclusive A$100 price is A$9.09. Net sales revenue is A$90.91.
The business has not “lost 10%” in a simple sense, but the amount retained as sales revenue has fallen by A$9.09 compared with the previous A$100 price.
That reduction can remove a large share of the contribution left after labour and other costs.
Decide how to handle existing clients
Options include:
Add GST on top from the effective date
This preserves the previous net sales price. It creates the largest visible customer increase.
Absorb part of the change
The business may choose a smaller increase and accept some reduction in net revenue. Calculate the annual impact before deciding.
Review the entire price
If the client has not had a review for years, separate the GST explanation from the broader commercial price. Be clear about the final amount rather than presenting a confusing stack of increases.
Change the scope
Where a customer cannot accept the new price, a smaller service may preserve the relationship without forcing the business to absorb the full difference.
Residential and commercial customers may see GST differently
A GST-registered commercial client may be able to claim GST credits where the normal requirements are met. A residential customer generally experiences the GST-inclusive amount as the final cost.
That does not change the business's obligation. It may change how the conversation feels.
Update every customer-facing place
Before the effective date, update:
- quote templates
- invoices and tax-invoice fields
- booking-page prices
- service descriptions
- recurring customer records
- payment links
- terms where prices are referenced
An old price on one page and a new price on the invoice creates unnecessary disputes.
The bottom line
GST turnover is based on business income, not profit. A business generally needs to register once the A$75,000 threshold test is met and must act within the required timeframe. Adding 10% and extracting GST from an inclusive price are different calculations. Existing residential and commercial clients may respond differently to the change.
Frequently asked questions
Short answers to common questions about this topic.
No. GST turnover is broadly based on business sales under the ATO's turnover rules, not the profit left after expenses.
