Thank you for your response today. It's helped a lot.
I'm sure my Italian husband would love it if I dragged him all over the EU so I can work without restriction
Unfortunately we have to assume he is definitely busy working in Italy and I'm the one that's off galavanting around.
The majority of my invoicing is done out of my UK company and the Italian company behaves like a management company. BUT having said that I can invoice out of my Italian company if I want to. At the moment I choose not to as the tax is higher for annual earnings over a certain level.
I would definitely not be entering another EU country to be an employee within it and when travelling to the UK it's mainly for client meetings. So it seems that so long as I'm travelling on a business trip rather than to 'work' for an extended period I'm generally OK.
So thanks again for your assistance. I feel a little more at ease now.
Regards, Deanne
