Claiming Input Tax on Over-Declared or Under-Declared Value of Import Permits
If you had over-declared or under-declared the value of your imports, you may need to inform Singapore Customs and make adjustments in your GST returns.
If you had under-declared the value of
your imports and under-paid GST, you need to pay the additional GST to
Singapore Customs by taking up a short payment permit. You can claim the total
GST amount as reflected in the original and short payment permit in your GST
return.
If you had over-declared the value of your imports and
over-paid GST, you can claim the GST amount as reflected in your import permit but
report the correct value of imports in your GST return.
Refer to Mistakes in
Import Declarations for detailed instructions on what you should do in
the above situations.
