What makes you think that?
The UAE can tax companies based on their effective place of management.
Same as if you have a
Dubai company with employees working from Dubai, but you manage the company from France. Then France can also tax that company.
How much they can tax depends on whether there is a tax treaty.
Obviously
Qatar and UAE will be less strict than France. But it's still a risk. I would say the risk of them going after your "offshore" company is significantly lower if you don't have local clients etc., but if they do, the problem is that you don't know what will happen. There is no case law, no rule of law, potentially high fines or even jail time.
That's why I would always try to set things up in a way that are clear for them to understand.
"No, I don't operate my
offshore company from here, of course. Everything I do here, I do through my local freezone company!" - clear.
vs.
"I don't have a local company here. I only have an
offshore company. Oh yeah, I live here. Yes, I sometimes work online for my offshore company from here. No, I don't think I have operations here, why would you want to tax me?" - not so clear...
