GST Registration and Refund

GST Registration and Refund

GST stands for Goods & Services Tax. It was first introduced on 1st April 1994 at 3%. In order to maintain its international competitiveness, the Singapore government began to collect GST rather than taxing corporate and top marginal personal income at a high rate of 40%*. It was a move from collecting direct to indirect taxes. Currently, Singapore’s GST rate stands at 7% and poised to increase by 9% sometime between 2021 and 2025.

What does this mean for a business owner?

As a business owner, your business might be required to register for and collect GST.

It would mean that you need to include GST in the prices for the products and services that you are selling or providing, and then pay the collected GST back to IRAS. You can claim back GST for your business purchases.

GST Registration

There are 2 types of GST registration:

1. Compulsory registration
2. Voluntary registration

1. Compulsory registration

As a business, it is required by law to register for GST when:

  • Your taxable turnover for the past 12 months ending Mar, Jun, Sep or Dec (referred to as “quarter”) is more than $1  million; or
  • You are making or intend to make taxable supplies and you can reasonably expect your taxable turnover in the next 12 months to be more than $1 million (e.g. signing of a sales contract or business agreement)

2. Voluntary registration

For businesses that have an annual turnover that is less than $1million, it is not required by law to register for GST but can voluntarily do so. Once registered, businesses must stay registered for a minimum of 2 years.

Company directors are also required to complete and pass 2 Elearning courses –  “Registering for GST” and “Overview of GST”, before registering for GST.
