Advance payment received from my customer in respect of works contract

If you've received an advance payment for a works contract, you'll need to account for GST on this amount. This is because works contracts are treated as a supply of services, and GST is applicable on advances received for services. You must issue an advance receipt voucher to your customer, charging GST on the amount received. Remember to declare this advance in your GST return and pay the applicable GST, which is considered inclusive of the GST amount.
