Last updated 14 February 2026

What is it?

The Import GST Deferment Scheme (IGDS) is administered by the Inland Revenue Authority of Singapore (IRAS).

This scheme is designed to alleviate the cash flow of taxable traders by deferring the imports’ Goods and Services Tax (GST) payment at the point of import.

Please note the following details when obtaining the import permits:

  • For import of non-dutiable goods with GST under deferment

    • Message Type = In-Non Payment (INP)

    • Declaration Type = APS (Approved Premises/Schemes)

    • Place of Receipt Code = IGDS

  • For import of dutiable goods with duty payable and GST under deferment

    • Message Type = In-Payment (IPT)

    • Declaration Type = DUT (Duty)

    • Place of Receipt Code = IGDS

  • For import of dutiable goods with duty exempted and GST under deferment

    • Message Type = In-Non Payment (INP)
