Enhanced VAT Return Service – Online Corrections Now Available

Following recent upgrades to the functionality of the online VAT return submission process, businesses and agents are advised that they are now able to make online corrections in respect of errors identified in previously submitted VAT returns. Previously, corrections would have required the manual completion of a VAT 652 MAN error correction form.

VAT returns can be amended up to a maximum of four years prior to the current date. When submitting a correction, businesses must provide a full and detailed explanation to enable the Customs and Immigration Division to process any additional tax due to or from the business as efficiently as possible. Relevant supporting documentation (for example, detailed VAT workings) may also be uploaded alongside the corrected return.

While the majority of corrections can now be completed online, there remain limited circumstances where the online facility is not available and a manual VAT 652 MAN submission will still be required.

Users should also note that newly submitted returns may not be immediately available for amendment, as the option to amend will only become available once processing has been completed within the system. In addition, where an amendment has been submitted, the updated return details may not be immediately reflected while standard validation checks are completed.

Care should be taken when submitting or amending VAT returns to ensure that the information provided is accurate, complete, and relates to the correct return period. Penalties may apply where incorrect or misleading information is submitted.

A guide on how to amend a VAT return in RMS online services is available on the Correcting a VAT Return Error webpage.
