Revenue has again indicated its concern about the level of Brexit readiness by some businesses here.
Revenue said that over the last three weeks, it has written to 90,000 businesses and directly contacted over 2,500 businesses by phone, as part of its Brexit trade engagement programme.
It said it will continue its direct phone contact with up to 14,000 business over the coming weeks as it works to support their efforts to be Brexit ready in a little over 90 days from now.
Lynda Slattery, head of Revenue's Brexit Policy Unit, said it had seen a welcome increase in the level of customs registrations with some 1,300 registrations completed in September alone.
But she added that some businesses seem to mistakenly believe that Brexit will not actually happen and are not getting Brexit ready.
"The truth is that Brexit takes full effect from January 2021 and there won't be any change in that," Ms Slattery said.
"This means that customs procedures will apply from 1 January to trade with and through Great Britain, regardless of the outcome of the current EU/UK talks," she stated.
"Given this reality, it is vital that businesses get Brexit ready now to avoid serious disruption to how their business operates and minimise what will otherwise be a potentially significant impact on their revenues," she added.
Currently 97% of the value of export trade to the UK and 93% of the value of the import trade from the UK is undertaken by businesses with an existing customs registration.
A customs registration provides a business with an EORI (Economic Operators Registration Identification) number which is an essential requirement to be able to complete customs formalities for trade with Great Britain from 1 January 2021.
Revenue is now asking each business to urgently take the following steps - get fully and accurately informed on what Brexit means for the business, undertake an immediate Brexit impact assessment and act on that assessment by taking all the actions needed to be ready on January 1.
Ms Slattery also encouraged businesses who are preparing or need to start preparing for Brexit to register for Revenue's Brexit seminars on October 5 and 6.
