UK employees have been able to travel to the EU on business with ease for the last 25 years. However, few have been aware of certain rules associated with business travel between EU member states.
A certain requirement that may have passed UK employers by, is the need to have an A1 form when conducting business in the EU.
An A1 form is simply a certificate issued by HMRC that proves an individual pays UK NICs. Why then would a UK worker or employer need to prove they pay UK NICs and why does it matter in the context of travelling to the EU on business?
This requirement has long been in place and in July 2020, the EU increased its enforcement of the rules for business travel, including the requirement to have an A1 form, before you travel.
As such, we have seen members being turned away from countries such as France and Spain as their workers have arrived without their A1 forms.
But why does it matter?
There is an EU rulebook for the temporary movement of workers between EU Member States, known as the Posted Workers Directive. Within this, a worker temporary working or visiting another Member State would be required to pay local NICs of that Member State on Day 1 of arrival, something UK employers would want to avoid.
But the rule only applies if the worker can prove they already pay social security in their host state – in our case this means the UK. Therefore, in advance of travel, UK employers and workers need to obtain an A1 form to avoid paying local social security in the Member State they will be travelling to.
There are two types of A1 form that UK employers should be aware of; a single-trip A1 form (you’ll need to fill out a form CA3822 in all cases) and a multi-state A1 form (CA8421).
The former is suitable for workers visiting or working in just one Member State within a single trip. The latter, is suitable for workers visiting or working in multiple Member States within one trip before returning to the UK.
Each individual who travels to the EU will require their own A1 form and will need to state the length of time they intend to visit that Member State.
However, A1 forms are valid for 24 months and if UK employers travel frequently, it would be sage to include on the form that workers could be visiting any Member State at any time for a 24 month period. This would save the UK employer and workers from updating their A1 form each time they made a trip and cuts down on the red tape.
So remember, before you travel, apply for an A1 form and send a copy in advance to the local labour authority in the State you are visiting; PS. it helps to travel with a copy as well!
