Key Takeaways
- The GST registration threshold is $75,000. A business or sole trader generally must register when current GST turnover or projected GST turnover reaches $75,000. Current turnover looks at the current month and previous 11 months; projected turnover looks at the current month and following 11 months. The threshold is based on turnover, not profit, and GST itself is excluded. The threshold for a non-profit body is $150,000. Taxi and ride-sourcing drivers generally must register regardless of turnover. The ATO says registration is required within 21 days of becoming aware that the threshold will be met.
- Quarterly BAS is the usual cycle for businesses with GST turnover below $20 million, unless the ATO requires a different cycle or the business chooses monthly reporting. 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 smaller business can also choose monthly reporting, which may suit a growing startup with high setup costs or a business that wants GST reporting closer to its day-to-day cash flow. A monthly activity statement is generally due on the 21st day of the following month.
- PAYG withholding is money withheld from wages, director fees and certain other payments, then reported and paid to the ATO. Small withholders, with annual withholding of $25,000 or less, generally pay quarterly. Medium withholders, with annual withholding from $25,001 to $1 million, generally pay monthly by the 21st day after the month ends. Large withholders above $1 million follow more frequent ATO payment dates.
- PAYG instalments are different from PAYG withholding. They are prepayments towards the expected income tax of a company, sole trader, partner or trust beneficiary. The ATO normally sets an instalment amount or rate using the latest tax information. Most affected small businesses report quarterly, but the actual frequency and amount shown on the ATO activity statement should be followed.
BAS and GST lodgement without the overwhelm
A straightforward answer for Chatswood business owners
A Chatswood business generally must register for GST when its current or projected GST turnover reaches $75,000, then report and pay GST through monthly, quarterly or, in limited cases, annual activity statements. Accurate BAS lodgement means reconciling sales, expenses, GST, payroll and PAYG records before submitting the figures to the Australian Taxation Office by the applicable due date.
Graham Chee, FCPA, CPA, GRCP and GRCA, principal of Local Knowledge, writes from a principal-led practice that combines FCPA-grade compliance with institutional experience at Goldman Sachs, BNP Investment Management and Merrill Lynch. Local Knowledge Pty Ltd is a CPA public practice and registered tax agent established in Mascot in 2003; the services described by Sydney Bookkeeping are delivered by that operating entity, with FCPA sign-off on every file.
For a cafe near Victoria Avenue, a sparky working across the Lower North Shore, or a growing business close to Chatswood Interchange, BAS can become stressful when receipts, payroll and bank transactions pile up meeting your Single Touch Payroll reporting obligations. Our job is to keep it simple, work through the records step by step and provide reasonable assurance that the activity statement is supported by properly reconciled books.
Six BAS and GST points to understand
The thresholds, reporting cycles and due dates that matter
The GST registration threshold is $75,000. A business or sole trader generally must register when current GST turnover or projected GST turnover reaches $75,000. Current turnover looks at the current month and previous 11 months; projected turnover looks at the current month and following 11 months. The threshold is based on turnover, not profit, and GST itself is excluded. The threshold for a non-profit body is $150,000. Taxi and ride-sourcing drivers generally must register regardless of turnover. The ATO says registration is required within 21 days of becoming aware that the threshold will be met.
Quarterly BAS is the usual cycle for businesses with GST turnover below $20 million, unless the ATO requires a different cycle or the business chooses monthly reporting. 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 smaller business can also choose monthly reporting, which may suit a growing startup with high setup costs or a business that wants GST reporting closer to its day-to-day cash flow. A monthly activity statement is generally due on the 21st day of the following month.
PAYG withholding is money withheld from wages, director fees and certain other payments, then reported and paid to the ATO. Small withholders, with annual withholding of $25,000 or less, generally pay quarterly. Medium withholders, with annual withholding from $25,001 to $1 million, generally pay monthly by the 21st day after the month ends. Large withholders above $1 million follow more frequent ATO payment dates.
PAYG instalments are different from PAYG withholding. They are prepayments towards the expected income tax of a company, sole trader, partner or trust beneficiary. The ATO normally sets an instalment amount or rate using the latest tax information. Most affected small businesses report quarterly, but the actual frequency and amount shown on the ATO activity statement should be followed.
Due dates can change where the date falls on a weekend or public holiday, and eligible clients of a registered tax or BAS agent may receive a different lodgement date under the ATO lodgement program. An agent extension should never be assumed. We confirm the applicable date for each Chatswood business and work backwards from it.
How BAS works in a real Chatswood business
From daily transactions to a lodged activity statement
The BAS cycle starts day to day, not on the due date. Sales, supplier bills, bank transactions, wages and owner purchases need to be recorded under the correct entity and given the correct GST treatment.
Consider a Chatswood cafe. Card settlement deposits may reach the bank after merchant fees are deducted. If the deposit is recorded as total sales, both income and GST can be understated. We reconcile the gross sales from the point-of-sale system, record merchant fees separately and match the net settlement to the bank.
For a local electrician, tools and materials may include GST, while some supplier charges, insurance items or government fees may not. A bank payment alone does not prove that a GST credit can be claimed. For taxable purchases above $82.50 including GST, the business generally needs a valid tax invoice before claiming the GST credit.
A growing Chatswood startup may have subscription costs, overseas suppliers, contractor payments and employee wages. Each category needs separate attention broader business cash-flow and financial guidance. GST does not apply to wages, and overseas purchases do not always follow the same treatment as an Australian supplier invoice. Contractor arrangements should also be reviewed carefully because calling someone a contractor does not settle their legal status.
Payroll creates another checkpoint. Amounts reported through Single Touch Payroll should agree with payroll records, general ledger accounts and the PAYG withholding reported on the activity statement. Fair Work Ombudsman requirements also apply: employee records generally need to be kept for seven years, and payslips must usually be issued within one working day of payday.
Company directors remain responsible for company obligations even when bookkeeping and lodgement work is outsourced. ASIC company details, the Australian Business Register information, payroll records and the accounting file should identify the correct legal entity. Changes to company details often need to be reported to ASIC within 28 days.
Before lodgement, we check the bank and credit card reconciliations, GST control accounts, sales reports, payroll, PAYG figures, director or owner transactions and unusual entries. This principal-led review provides reasonable assurance that the BAS is consistent with the available records.
Common BAS errors we fix
Small issues that can create larger reporting problems
Recording only the net amount received from card processors, delivery platforms or online marketplaces instead of recording gross sales and fees separately.
Claiming GST on wages, superannuation, bank interest, private spending or supplier invoices where no GST was charged.
Missing GST credits because receipts, supplier bills or commercial rent invoices were not entered before the BAS was prepared.
Using the wrong GST code for GST-free sales, exports, food items, government charges, insurance settlements or overseas purchases.
Claiming all vehicle, phone or home-office costs without separating the private portion from the business portion.
Reporting PAYG withholding that does not agree with payroll reports and Single Touch Payroll submissions.
Lodging from an unreconciled bank feed, leaving duplicate transactions, missing transfers or old suspense-account balances in the books.
Using the wrong accounting basis. A business reporting GST on a cash basis records transactions differently from one reporting on a non-cash basis.
Preparing the activity statement under the wrong ABN or entity after a company, trust or sole trader arrangement has changed.
Treating the BAS amount as spare cash during the quarter, then discovering there are not enough funds available by the payment date.
Our step-by-step BAS process
How we help Chatswood businesses stay on top of lodgement
Confirm the obligations
We check the legal entity, ABN, GST status, reporting basis, BAS cycle, PAYG registrations and ATO due date. We also identify missing activity statements or earlier periods that may need attention.
Bring the books up to date
We organise sales, purchases, payroll and bank transactions, then request any missing tax invoices or explanations. Bank accounts, credit cards and clearing accounts are reconciled rather than relying only on bank-feed matches.
Review and lodge
GST, PAYG withholding and PAYG instalment figures are checked against the underlying records. Graham Chee provides FCPA sign-off on every file before an approved activity statement is lodged through Local Knowledge Pty Ltd as the registered tax agent.
Plan for the next due date
We confirm the amount and payment date, explain anything unusual in plain English and set the next records deadline. Regular GST and payroll set-asides can make the next BAS easier on cash flow.
BAS questions Chatswood owners often ask
Practical answers for small businesses, trades and startups
Q.My turnover has just passed $75,000. What should I do?
Check both current and projected GST turnover rather than waiting until the end of the financial year. If the business is required to register, the ATO generally allows 21 days from when you become aware that the threshold will be reached. The effective date matters because invoices and prices may need to include GST from that date.
Q.Should my Chatswood business lodge monthly or quarterly?
Businesses with GST turnover below $20 million generally report quarterly unless the ATO directs otherwise or they choose monthly reporting. Monthly reporting can suit a business with significant GST credits or one that wants reporting closer to its trading cycle, but it also requires the books to be completed more often. We can explain the practical effect before a cycle is changed.
Q.What happens if I cannot pay the BAS by the due date?
Lodge the BAS on time where possible, even if the full amount cannot be paid. Lodgement and payment are separate obligations, and late lodgement can add avoidable penalties. The ATO may consider a payment plan based on the circumstances, but interest can continue to apply and approval is not guaranteed.
Q.Can I claim GST if I have lost the receipt?
It depends on the amount and the evidence available. For a taxable purchase above $82.50 including GST, a valid tax invoice is generally required before claiming the GST credit. Ask the supplier for a replacement invoice rather than guessing. Some limited ATO exceptions may apply, but they should be considered case by case.
Q.Does using a registered agent give me more time?
Eligible clients included in a registered agent's lodgement program may have later dates for some activity statements. The extension is not automatic for every business or period. We confirm the actual ATO due date and ask for records early enough to complete a proper review.
