Re: Question about Dubai
This sound more complicated when you're trying to figure out these things with respect to the multiple citizenships and residencies that you hold.
I'm just wondering whether simply "declaring" your Pakistani citizenship is going to suffice in a case when you wish to pay taxes in Pakistan. Don't you have to show that you've maintained residency in Pakistan for x number of years before you started working in the Emirates?
In the Canadian context, there are various categories of residency that need to be acknowledged by the tax payer and approved by the Revenue Agency to determine the tax paying situation. I think we have the Factual-Resident, Non-Resident and Deemed-Non-Resident categories... and each has its own provisions.
Treaties can simplify things greatly though - I think Canada had its treaty with the Emirates a few years back which is why we've seen quite a few people take advantage of opportunities there.
