How to Fill Out a BAS Statement: Step by Step Guide for Australian Businesses
What Is a BAS Statement?
If you run a business in Australia, understanding how to fill out a BAS statement is essential. A Business Activity Statement (BAS) is used to report and pay your GST, PAYG withholding, and other tax obligations to the Australian Taxation Office (ATO).
Getting your BAS right ensures you stay compliant and avoid penalties. Many businesses choose to work with professionals like Blue Duck Bookkeeping services to simplify the process and reduce errors.
Who Needs to Lodge a BAS?
You are required to lodge a BAS if your business is registered for GST. Depending on your turnover, this may be done monthly, quarterly, or annually.
If you are unsure about your obligations or deadlines, working with Blue Duck Bookkeeping services can help ensure everything is submitted on time and accurately.
How to Fill Out a BAS Statement Step by Step
Learning how to fill out a BAS statement becomes much easier when you break it down into clear steps.
1. Gather Your Financial Records
Start by collecting all relevant data for the reporting period. This includes sales invoices, purchase receipts, payroll records, and bank statements.
Accurate record keeping is critical. Using Blue Duck Bookkeeping services ensures your data is always organised and ready for BAS preparation.
2. Calculate Your Total Sales (G1)
At label G1, you need to report your total sales for the period. This includes both GST inclusive and GST free sales.
Ensure all income streams are captured to avoid discrepancies.
3. Report GST on Sales (1A)
Next, calculate how much GST you collected from your sales. This amount is reported at label 1A.
Most businesses calculate this as one eleventh of their GST inclusive sales, but always check your specific circumstances.
4. Calculate GST on Purchases (1B)
At label 1B, you claim the GST credits for eligible business expenses. Only include purchases that have GST applied and are used for business purposes.
Missing valid claims can cost your business money, which is why many rely on Blue Duck Bookkeeping services for accuracy.
5. Complete PAYG Withholding (If Applicable)
If you have employees, you must report PAYG withholding amounts. This ensures you meet your obligations as an employer.
6. Review and Lodge Your BAS
Before submitting, double check all figures for accuracy. Errors can lead to penalties or delays.
Once confirmed, lodge your BAS through the ATO portal, your accounting software, or with the help of a registered BAS agent.
