Hello, sydney.

The reason your Business Activity Statement (BAS) G1 may be showing a wrong amount typically happens due to the following reasons:

• Duplicate entries might be inflating the total sales amount.
• Non-taxable items may have been mistakenly included in the G1 field.

To identify and resolve the issue, you can check and follow this process:

• Double-check all sales transactions for the relevant period.
• Review each transaction to ensure that the correct tax codes were applied (e.g., GST, GST-free, or Exempt).

By carefully reviewing your sales transactions and verifying the tax codes, you’ll be able to pinpoint and correct the cause of the incorrect G1 amount.
