If the AAD page is locked, can I still save the return?

Yes. You can still save the W1 Return if the AAD page is locked. If the AAD page is locked it may be because someone else in your organisation, or HMRC, has another Declaration open for the same warehouse.

If this means that your W1 Return will be late please contact the eCustomer Support Helpdesk on 0300 200 3701 who will notify the National Warehouse Return Centre (NWRC) in Glasgow that you are waiting to submit your W1 Return.
