Key Takeaways
- The GST registration threshold is $75,000. You generally need to register when your current or projected GST turnover reaches $75,000 over a 12-month period. The threshold is $150,000 for a non-profit body. Taxi and ride-sourcing drivers generally need to register regardless of turnover. GST turnover is based on sales, not profit, and excludes GST itself and certain other amounts.
- Registration is generally required within 21 days of becoming aware that the threshold will be reached. A new business should check both actual sales and its realistic sales forecast. Waiting until year-end can create backdated GST, invoice and cash-flow problems.
- Quarterly BAS lodgement generally applies when GST turnover is below $20 million. The standard quarterly due dates are 28 October for July to September, 28 February for October to December, 28 April for January to March, and 28 July for April to June.
- Monthly GST reporting is generally required when GST turnover is $20 million or more. A business below that threshold can also choose monthly reporting. Monthly activity statements are normally due on the 21st day after the end of the reporting month. If a due date falls on a weekend or public holiday, the ATO generally moves it to the next business day.
- PAYG withholding is separate from GST but is often reported on the same activity statement. A small withholder that withholds $25,000 or less each year generally reports quarterly. A medium withholder that withholds $25,001 to $1 million generally reports monthly. Large withholders above $1 million have more frequent payment obligations set by the ATO.
BAS and GST Lodgement Without the Stress
A straightforward answer for Randwick business owners
If your Randwick business has GST turnover of $75,000 or more, you generally need to register for GST and lodge activity statements by the Australian Taxation Office due dates. Most businesses with GST turnover below $20 million lodge quarterly, while businesses at or above $20 million generally lodge monthly.

Six BAS and GST Points to Understand
The thresholds, cycles and obligations that matter
The GST registration threshold is $75,000. You generally need to register when your current or projected GST turnover reaches $75,000 over a 12-month period. The threshold is $150,000 for a non-profit body. Taxi and ride-sourcing drivers generally need to register regardless of turnover. GST turnover is based on sales, not profit, and excludes GST itself and certain other amounts.
Registration is generally required within 21 days of becoming aware that the threshold will be reached. A new business should check both actual sales and its realistic sales forecast. Waiting until year-end can create backdated GST, invoice and cash-flow problems.
Quarterly BAS lodgement generally applies when GST turnover is below $20 million. The standard quarterly due dates are 28 October for July to September, 28 February for October to December, 28 April for January to March, and 28 July for April to June.
Monthly GST reporting is generally required when GST turnover is $20 million or more. A business below that threshold can also choose monthly reporting. Monthly activity statements are normally due on the 21st day after the end of the reporting month. If a due date falls on a weekend or public holiday, the ATO generally moves it to the next business day.
PAYG withholding is separate from GST but is often reported on the same activity statement. A small withholder that withholds $25,000 or less each year generally reports quarterly. A medium withholder that withholds $25,001 to $1 million generally reports monthly. Large withholders above $1 million have more frequent payment obligations set by the ATO.
PAYG instalments are prepayments towards expected income tax. The ATO generally places a business or individual into the instalment system after a tax return is assessed. Instalments are usually reported quarterly, either using an ATO amount or a rate applied to instalment income. A variation may be possible when expected tax changes, but it needs to be reasonable and properly supported.
Current BAS Due Dates for 2025–26
Put these dates in your business calendar
The standard quarterly BAS dates for the 2025–26 financial year are:
July to September 2025: 28 October 2025 October to December 2025: 28 February 2026 January to March 2026: 28 April 2026 April to June 2026: 28 July 2026
Eligible quarterly clients who lodge electronically through a registered tax or BAS agent may receive dates under the ATO agent lodgment program. These commonly include 25 November for quarter one, 28 February for quarter two, 26 May for quarter three and 25 August for quarter four.
An agent concession is not automatic in every case. Monthly statements, overdue obligations and other circumstances can have different dates. The date shown in the ATO system for the business should always be checked.
The payment date is generally the same as the lodgement date broader financial guidance for business owners. If cash flow is tight, lodge the BAS on time and speak with the ATO or your registered agent about the next step. Delaying lodgement usually makes the position harder to manage, and interest may continue to apply to outstanding amounts.
How BAS Works in Day-to-Day Randwick Businesses
Practical examples from suburban Sydney
A cafe near Belmore Road or The Spot may receive money through its point-of-sale system, delivery platforms, cash and card settlements. The bank deposit from a delivery platform is often net of fees. Recording only that deposit can understate sales and miss GST credits on the platform fees. We reconcile the gross sales, fees and settlement amount step by step.
A Randwick electrician or builder may receive deposits and progress payments while buying materials from several suppliers. The GST timing depends partly on whether the business reports on a cash or non-cash basis. Businesses with aggregated turnover below $10 million can generally choose cash accounting for GST, subject to the ATO rules. Supplier invoices also need to be checked before GST credits are claimed.
A medical or allied health clinic near the Randwick Health and Innovation Precinct may make a mix of GST-free and taxable sales. Some recognised health services can be GST-free when the legal conditions are met, but product sales, reports, room hire and other services may be treated differently. Assuming that every clinic receipt is GST-free is a common mistake.
A Kensington startup may have subscription income, online payment fees and overseas software costs. Foreign invoices do not always contain Australian GST, while some overseas suppliers are registered for Australian GST. Each transaction should be coded from the invoice rather than guessed from the supplier's location.
These checks give reasonable assurance that the BAS matches the books, payroll records and supporting documents before it is lodged.
Common BAS Errors We Fix
Small mistakes can flow through several reporting periods
Reporting net bank deposits instead of gross sales from card processors, booking platforms or delivery services.
Claiming GST on wages, superannuation, loan repayments, private expenses, bank fees or other items that do not include claimable GST.
Missing GST credits because supplier invoices were coded as GST-free or left unreconciled.
Claiming a GST credit without adequate evidence. For purchases above $82.50 including GST, a valid tax invoice is generally needed before the credit can be claimed.
Treating all food, health, education or property transactions the same even though GST treatment can vary between individual supplies.
Using cash figures when the business reports on a non-cash basis, or recording invoices twice after they are later matched to bank transactions.
Leaving PAYG withholding out of the BAS or failing to reconcile BAS payroll figures with payroll reports and Single Touch Payroll records.
Posting owner drawings, director loans, asset purchases or finance transactions entirely to ordinary expenses.
Carrying old bookkeeping errors into each new quarter instead of correcting them through an appropriate current or revised activity statement.
Our Step-by-Step BAS Process
How we help keep Randwick businesses lodged accurately and on time
Gather and Reconcile
We collect the relevant bank, card, payment platform, sales, purchase and payroll records. Bank accounts and clearing accounts are reconciled so unexplained differences can be followed up.
Check GST and Payroll
We review GST codes, tax invoices, unusual transactions, payroll reports, PAYG withholding and PAYG instalments. We also check whether the GST reporting basis and lodgement cycle remain suitable.
Review and Confirm
A clear BAS summary is prepared and questions are resolved with the owner or director. Our principal-led process includes FCPA sign-off on every file before lodgement authority is requested.
Lodge and Stay on Top
Once approved, the activity statement is lodged through the registered practice. We confirm the amount and due date, record the lodgement and identify bookkeeping items that should be corrected before the next cycle.
BAS Is Only One Part of Good Business Records
Payroll, company records and cash flow also matter
The ATO activity statement needs to agree with the underlying accounts. Single Touch Payroll does not replace the need to report PAYG withholding on the BAS, and super guarantee payments have their own quarterly deadlines.
Fair Work Ombudsman guidance requires employers to keep employee records for seven years and provide pay slips within one working day of payday. Payroll records should support the wages and withholding amounts reported to the ATO.
For companies, ASIC expects directors to keep adequate financial records and understand whether the company can meet its debts when they fall due. The ASIC annual review date is separate from the BAS cycle, so it should have its own reminder.
Keeping these records up to date makes each BAS easier to review and gives the owner a clearer view of cash flow before tax and supplier payments fall due.
BAS and GST Questions Randwick Owners Ask
Plain-English answers to common concerns
Q.Do I need to register for GST as soon as I start my Randwick business?
Not always. Registration is generally compulsory once current or projected GST turnover reaches $75,000 over a 12-month period. You may choose to register earlier, but that creates ongoing reporting duties. Taxi and ride-sourcing drivers generally need to register regardless of turnover.
Q.Should I lodge quarterly or monthly?
Most small businesses with GST turnover below $20 million lodge quarterly. Monthly reporting is generally compulsory at $20 million or more, although a smaller business can elect monthly reporting. Monthly reporting may suit a business that regularly receives GST refunds, but it also means more frequent bookkeeping and due dates.
Q.What if I cannot pay the BAS by the due date?
Lodge it on time if possible. Lodgement and payment are separate obligations, and an outstanding amount may be easier to discuss once the correct BAS has been filed. A registered agent can help you understand the balance and contact the ATO about options, but approval of any payment arrangement is an ATO decision.
Q.Are all medical and allied health services in Randwick GST-free?
No. Some health services are GST-free when they are supplied by a recognised professional and meet the relevant treatment requirements. Other services, products, reports or room arrangements may be taxable. Each supply should be checked rather than applying one GST code to the whole clinic.
Q.Can an old BAS mistake be corrected?
Often, yes. The right method depends on the type, size and age of the error. It may be possible to correct an eligible GST error in a later BAS, while other issues require a revision of the original statement. We first reconcile the period and review the supporting records before recommending the appropriate correction.
