Clear BAS and GST support for Perth sole traders, ABN holders, companies and small businesses. Hamro Accountant Perth can help organise your records, review GST treatment, reconcile business transactions, prepare BAS information and keep your reporting process easier to understand from one period to the next.
General information only. BAS labels, reporting cycles, GST treatment and PAYG obligations depend on your registrations and business circumstances.
A Business Activity Statement, or BAS, is used by registered businesses to report tax obligations such as GST. Depending on the business, the statement can also include PAYG instalments, PAYG withholding and other tax amounts. If your business is registered for GST, the ATO generally requires you to lodge a BAS for the reporting periods assigned to you.
The labels on your activity statement depend on the tax obligations registered to the business. Not every business reports every item below.
Report GST-related sales and purchases using the labels relevant to your business and reporting method.
Some businesses and individuals make PAYG instalments during the year toward their expected income tax liability.
Employers and other businesses with withholding obligations may report PAYG withholding through their activity statements.
Some businesses can have additional activity-statement labels based on their registrations and tax obligations.
BAS preparation is easier when the records are reviewed in the right order rather than trying to calculate GST from scattered receipts at the deadline.
Sales, purchases, bank transactions, invoices and receipts need to be recorded so the BAS starts from complete business data.
Bank accounts and relevant balance-sheet or transaction records are checked so unexplained items do not flow into the BAS unnoticed.
GST coding, taxable and GST-free transactions, eligible GST credits and any PAYG obligations are reviewed against the business records.
The activity-statement figures are prepared and reviewed before lodgment so you can understand the amounts being reported.
Once the figures are ready, the BAS can be lodged through the appropriate channel and you can plan for any amount payable by the due date.
For most businesses, GST registration is generally compulsory when annual GST turnover reaches $75,000 or more. The ATO generally requires registration within 21 days of becoming required to register.
Businesses below the threshold can choose to register voluntarily. Taxi and ride-sourcing passenger services have special GST registration rules and are not covered by the normal turnover threshold in the same way.
See rideshare GST guidanceGST turnover is different from business profit.
Voluntary registration may be possible below the threshold.
Ride-sourcing passenger services have special GST registration rules.
Under Simpler BAS, which is the default GST reporting method for eligible small businesses, the GST section focuses on three main labels: total sales, GST on sales and GST on purchases.
Simpler reporting does not remove the need for correct bookkeeping. Transactions still need to be classified properly so the totals behind the BAS can be supported.
Prepared from the business records according to the GST reporting method.
The GST collected or payable on relevant taxable sales during the period.
Based on eligible business purchases and the tax invoice requirements that apply.
Do not assume every business has the same BAS deadline. Use the due date shown for your activity statement or the date confirmed for your business.
Some businesses report monthly. Monthly BAS lodgment is generally due on the 21st day of the following month, subject to the specific due date that applies.
Many small businesses report quarterly. Standard quarterly due dates vary by quarter, and agent or electronic lodgment concessions can differ depending on eligibility.
Some businesses that are voluntarily registered for GST and remain below the compulsory registration threshold may be eligible to report GST annually.
BAS figures are only as reliable as the records behind them. If bank transactions are unreconciled, invoices are missing or GST codes are inconsistent, the activity statement can become harder to prepare and explain.
Regular bookkeeping also helps you see the GST and PAYG amounts building up during the reporting period rather than discovering the position only at the deadline.
Explore Bookkeeping & AccountingCheck that business income for the period has been recorded completely.
Support business purchases and any GST credits being claimed.
Identify duplicated, missing or unexplained transactions before BAS preparation.
Check taxable, GST-free, input-taxed and non-GST transactions where relevant.
Where the business employs staff, relevant payroll records should align with the reporting period.
Prior lodgments can help identify adjustments, recurring issues or inconsistent coding.
BAS problems are often record-keeping problems first. Fixing the process can be more useful than correcting the same issue every quarter.
Missing source documents can make GST credits harder to support and create uncertainty when transactions are reviewed.
Duplicate, uncategorised or missing transactions can affect sales, purchases and GST figures.
Treating every transaction as containing GST can be incorrect because GST treatment varies by the type of sale or purchase.
Mixed-use expenses may require apportionment rather than treating the full amount as a business purchase.
Leaving BAS work until the deadline can make it harder to resolve missing records, coding issues or cash-flow problems before payment is due.
Accounting software can automate calculations, but the transactions and GST coding still need to be reviewed for accuracy.
A business with a handful of invoices is different from a restaurant with daily sales, a tradie using subcontractors, a cleaning company with staff, or a rideshare driver with special GST rules. We tailor the BAS workflow around the actual activity and records involved.
These Perth services connect directly with the records and obligations that often feed into BAS preparation.
Keep transactions reconciled and GST coding cleaner throughout the period instead of rebuilding the books at BAS time.

Explore small business accountingThese answers are general information only. Your BAS requirements depend on the tax roles, GST registration and reporting cycle attached to your business.
A BAS can be used to report GST, PAYG instalments, PAYG withholding and other tax obligations. The actual labels shown depend on the registrations and obligations attached to the business.
No. Having an ABN by itself does not automatically create a BAS requirement. BAS obligations arise from registrations and tax roles such as GST, PAYG instalments or PAYG withholding.
For most businesses, GST registration is generally compulsory when annual GST turnover reaches $75,000 or more. The ATO generally requires registration within 21 days of becoming required to register. Special rules apply to taxi and ride-sourcing passenger services.
Businesses can have monthly or quarterly reporting cycles, and some voluntarily registered businesses below the compulsory GST threshold may be eligible for annual GST reporting. Use the due date and reporting cycle assigned to your business.
Simpler BAS is the default GST reporting method for eligible small businesses. The main GST labels are G1 total sales, 1A GST on sales and 1B GST on purchases.
Yes. The first step is usually to understand what records are available, bring the bookkeeping up to date where possible, reconcile the accounts and identify any missing information before preparing the BAS.
Accounting software can calculate and summarise BAS information, but the result still depends on the underlying transactions, GST coding, reconciliations and records being correct.
We can help review the available business records and BAS position. The appropriate next steps depend on which periods are outstanding, what information is available and whether earlier lodgments need review.
Tell us briefly what your business does, whether you are registered for GST and whether your bookkeeping is up to date. We can then start with the BAS, GST or record-keeping support relevant to your situation.
