1

Gather Your Inputs

First, identify your total sales and purchases for the quarter, including GST. Also, gather your PAYG withholding and instalment amounts. For example, let's say your total sales are $22,000 (including GST) and your total purchases are $11,000 (including GST). Your PAYG withholding is $1,000 and PAYG instalment is $500.

2

Calculate GST on Sales and Purchases

Next, calculate the GST on your sales and purchases. The GST rate in Australia is 10% of the GST-inclusive amount. For sales: $22,000 / 11 * 10 = $2,000. For purchases: $11,000 / 11 * 10 = $1,000.

3

Apply the BAS Calculation Formula

Now, apply the formula to find the net GST. Using the numbers from our example: Net GST = $2,000 (GST on sales) - $1,000 (GST on purchases) = $1,000. This means you have a net GST amount of $1,000 to pay.

4

Report PAYG Withholding and Instalments

Report your PAYG withholding ($1,000) and PAYG instalment ($500) as is. These amounts are not subject to the GST calculation but are part of your overall BAS submission.

5

Combine Your Calculations for BAS Submission

Finally, combine your net GST amount with your PAYG withholding and instalment amounts for your BAS submission. In our example, you would report a net GST liability of $1,000, PAYG withholding of $1,000, and PAYG instalment of $500.

Using the BAS Calculator for Convenience

While manual calculations are educational, using an online BAS calculator can save time and reduce errors. These calculators will prompt you for the necessary inputs and perform the calculations automatically, providing you with the figures you need for your BAS submission.

Introduction to BAS Calculator

The Business Activity Statement (BAS) is a crucial document for Australian businesses, helping them report and pay their Goods and Services Tax (GST), Pay As You Go (PAYG) withholding, and PAYG instalments. While there are online calculators available, understanding how to calculate BAS manually is essential for a deeper grasp of your business's financial obligations. In this guide, we will walk you through the steps to calculate your BAS manually.

Prerequisites

Before you start, ensure you have the following information:

  • Total sales (including GST)
  • Total purchases (including GST)
  • PAYG withholding amounts
  • PAYG instalment amounts

Understanding the BAS Calculation Formula

The BAS calculation involves determining the net GST amount payable or refundable. The formula is: [ ext{Net GST} = rac{ ext{GST on Sales} - ext{GST on Purchases}}{11} ] For PAYG withholding and instalments, you will report these amounts as is, without additional calculations.
