Will you be taxed twice on the same income?
The UK has Double Taxation Agreements (DTAs) with over 130 countries. Select your destination to see whether a treaty exists, which country taxes what, and how the tie-breaker rules work.
One income, one tax bill
DTAs prevent the same income being taxed in two countries. They also set the tie-breaker rules when both countries claim you as a resident.

Where are you living or planning to move?
DTAs only eliminate double taxation β you still pay tax somewhere. The rules can be complex; always confirm your position with a cross-border tax adviser.

Guidance, not advice. DTA summaries are simplified for general awareness. Treaty interpretation is complex β article-level details, protocol amendments and anti-avoidance provisions are not shown. Always consult a qualified cross-border tax adviser before making decisions based on treaty treatment.
