Advance Ruling System for GST

You may apply for an advance ruling to find out from IRAS how the GST Act applies to particular business arrangements or transactions.

The Advance Ruling System

To provide greater clarity and certainty to taxpayers, the Comptroller of GST (CGST) operates an advance ruling system.

The system provides written interpretation on how specific provisions of the GST Act apply to a particular business arrangement or a specific transaction.

The advice or clarification given under the advance ruling system is legally binding on the CGST.

The advance rulings will not be published as they are private and confidential.

Who Should Apply

As a rule of thumb, it is the supplier's responsibility to ask for an advance ruling on the taxability of his supply of goods or services. The supplier and his customer may also submit a joint application.

If you are under GST Group registration, the application should only be made by a member of the GST Group.

How to Apply

To apply for a ruling, you must submit the following at least 1 month before the filing deadline of the relevant GST return to the CGST:

  1. GST F19: Application for GST Advance Ruling (132KB) form;
  2. An application fee of $620 (inclusive of GST); and
  3. A written ruling request providing:
    1. A comprehensive description of the proposed arrangement;
    2. Issue(s) to be considered;
    3. Propositions of the law that relate to the issues raised in the request including the relevant sections of the GST Act;
    4. Any outcome of and reference to the ruling issued on a previous request made on the same or a similar arrangement; and
    5. A draft ruling.

When the CGST Will Not Rule or May Decline to Rule

The CGST will not rule or may decline to rule when:

  1. The matter on which the ruling is sought:
    1. Involves the interpretation of a foreign law;
    2. Requires the CGST to form an opinion as to a generally accepted accounting principle or a commercial practice; or
    3. Is subject to an objection or appeal, whether in relation to you or any other person.
  2. The correctness of the ruling depends on the making of assumptions. The assumptions can be in respect of a future event or any other matter.
  3. An assessment (excluding an assessment of any estimated tax) relating to you, the arrangement and a period to which the proposed ruling would apply, has been made, unless the application is received by the CGST before the date of assessment is made.
  4. The CGST has embarked on an audit or investigation on how any provision of the GST Act applies to you or other similar arrangements.
  5. In the CGST's opinion, you are not seriously contemplating the arrangement for which the ruling is sought or that the application is frivolous or vexatious.
  6. You have not provided, within the specified timeframe, sufficient information in spite of the CGST's request for additional information.
