Top 10 common GST mistakes in BAS reports

It’s easy to make a mistake when preparing your BAS. The key is to be aware of common pitfalls so you can avoid them.

Thankfully, with online accounting software, preparing your own Business Activity Statement (BAS*) is easier.

Even so, the ATO has identified a number of mistakes commonly made in the BAS reporting form.

Here are the top 10 mistakes that I see regularly.

1. Accidental ‘double dipping’ on GST

Many business owners make mistakes in the Hire Purchase/Lease of Vehicle of Plant or Equipment area of the BAS. Initially, the client (or their accountant) will claim the full GST component in the first quarter that they purchase their vehicle.

The confusion sets in when they record their regular monthly payments. The client will either continue to code it as a GST or as a Capital Expense. Both the tax codes GST and CAP appear on their BAS Reporting sheet, effectively causing them to ‘double dip’ on the GST.

Always check your purchase invoice and BAS records to make sure you code your monthly repayments accurately.

2. Incorrect tax codes in your chart of accounts

I would advise you to ask your accountant to provide a default chart of accounts or ask a BAS agent to set up your tax codes before you begin using your online accounting software. You can look up an experienced accountant near you here.

3. Claiming GST against all expenses

There are expenses that do not have a GST component. They include:

  • Motor vehicle registrations
  • Bank charges
  • ASIC fees
  • Paypal transaction fees
  • Google Adwords
  • Interest and director fees / drawings

4. Claiming GST against all sales

Some services and products in the medical and health care areas also do not include GST. Also, basic food for human consumption does not include GST.

5. Including wages and superannuation in G11 as a purchase

You are to report wages in W1 on your BAS statement. They are not an expense to be included in G11, which is for non-capital purchases.

Superannuation is not required to be included as part of your gross wage in W1.

6. Forgetting to include all cash sales and purchases

You can get into a lot of trouble if you discount the GST when receiving payments by cash.

The ATO has a sophisticated process of cross-matching data, especially in the building and construction industry where business owners are obliged to submit a Taxable Payments Report annually, so make sure you declare all cash payments.

On the flip side, make sure you discuss all genuine tax deductions and GST credits with your bookkeeper or accountant.

7. Claiming on GST for private purchases

Items like personal loans, director’s fees and any other purchase for private consumption cannot have the GST credit collected on your BAS Statement.

8. Reporting purchases of capital items with the wrong tax code

If you purchase a business asset costing more than $1000, you need to report these in G10 under capital purchases in the BAS and not G11. If in doubt, check with your accountant.

9. Not including capital sales in G1 (Total Sales)

This includes the sale of motor vehicles, a trade-in or office equipment.

10. Claiming GST credits on purchases where the supplier is not registered for GST

Check the source invoice to see if it has GST or if it is a tax invoice. When in doubt, go to the ABN lookup page and type in the supplier’s ABN number or look up their business name to check.

Suppliers are required by law to provide you with an ABN when you purchase goods or services. If a supplier refuses to quote an ABN, you may need to withhold an amount of payment for that supply called “No ABN withholding”.

This amount is 46.5 percent of the total payment owed unless the following is provided:

1. An invoice or some other document is supplied with an ABN quoted

2. The ABN of the supplier’s agent is quoted

3. The supplier is not entitled to an ABN or required to as the payment is less than $75

As a business owner, it’s important to develop good record-keeping habits and avoid unnecessary mistakes.

RESOURCE: How to register your business for GST

Make sure you take the time to stay up to date by reading the bulletin from the ATO when it comes with your quarterly BAS (instead of throwing it straight into the bin). The ATO also hosts free webinars from time to time.

If you find all this too time-consuming or too difficult, the best way to prepare your BAS correctly is to engage the services of a qualified BAS or Tax Agent.

*According to the ATO, the BAS is used to report and pay a number of tax obligations, including GST, pay as you go (PAYG) instalments, PAYG withholding and fringe benefits tax.
