Smart GST Categorisation for Australian small businesses
Group expenses into sensible GST and BAS categories for quarterly reporting. BAS Bright is built for Australian sole traders, rideshare and delivery drivers, contractors, tradies, freelancers, consultants and small business owners who want clearer quarterly records without turning every BAS period into a spreadsheet marathon.
The goal is practical: record income and purchases throughout the quarter, check the GST treatment, apply business-use percentages where needed, and turn those details into a plain-English BAS estimate. BAS Bright helps estimate common ATO GST labels including G1, G2, G3, G10, G11, 1A, 1B and the net GST position at label 9.
Why this matters before BAS time
Most BAS stress does not start on lodgement day. It starts earlier, when receipts are missing, platform statements are unclear, GST-free sales have not been separated, or a mixed-use expense has been claimed at 100% business use without supporting notes. A simple record-keeping workflow makes every quarter easier to review.
BAS Bright does not replace your accountant, tax agent or registered BAS agent. It provides educational information and estimates only. The value is in preparing cleaner numbers, clearer reports and better questions before you lodge through the ATO or seek professional advice.
How BAS Bright helps
1. Calculate GST
Use the free GST calculator for GST-inclusive and GST-exclusive amounts, then apply a business-use percentage for mixed-use purchases such as fuel, EV charging, phone bills, internet or vehicle costs.
2. Estimate BAS labels
BAS Assist organises sales, capital purchases and non-capital purchases into a quarterly GST summary so you can see an estimated payable or refund position.
3. Save quarter history
Registered users can save estimates, revisit previous quarters and download a BAS summary PDF for their records or professional review.
4. Prepare for Receipt AI
Receipt AI is planned for OCR receipt scanning, merchant recognition, GST extraction, smart categorisation, receipt storage and quarterly reporting.
Records to keep
Keep tax invoices, receipts, bank records, sales reports, platform statements, merchant settlement reports, vehicle logs, odometer notes and calculations used to support business-use percentages. For rideshare and delivery drivers, gross fares and platform deductions should be reviewed carefully because platform fees may need to be recorded separately from sales.
For larger purchases, equipment, laptops, vehicles and other assets, check whether the item is a capital purchase. In BAS Bright, ordinary operating expenses generally flow to G11, while capital purchases generally flow to G10. Where GST treatment is uncertain, ask a registered professional before relying on the figure.
Useful examples
Fuel or EV charging
If a $110 fuel receipt includes GST and the vehicle is 80% business use, the estimated GST credit is generally based on one-eleventh of the amount multiplied by 80%, subject to eligibility and records.
Mobile phone bill
A mixed-use phone bill needs a business-use percentage. BAS Bright lets you record the total, GST treatment and business-use allocation rather than assuming the full amount is claimable.
New laptop or vehicle
Capital items can belong at G10 rather than G11. BAS Bright includes category defaults to reduce misclassification, while still leaving “Other” items flexible where judgement is needed.
Platform income
Rideshare and marketplace users should review gross sales, other income and platform deductions separately so BAS labels are easier to explain and reconcile.
