If you’re a VAT-registered business, you’ll be accounting for the import VAT on your VAT Return – so you must select method of payment ‘G’ when completing your supplementary declaration. You can submit declarations individually or in batches, and you can also submit more than one supplementary declaration for each entry in your own records.

After you submit

When your supplementary declaration is accepted, CHIEF will send a customs response message telling you how much import VAT and Customs Duty you owe.

If you’re not VAT registered, payment will be taken from your deferment account on the 15th day of the following month.
