Are you being taxed twice ? I had two recent cases where individuals were being taxed twice, in the UK and Norway.
There are many double-tax treaties between the UK and other countries, both inside and outside the EU. These are in place to stop individuals and companies being taxed twice for working and operating in a different country and their home country. This can especially adversely affect individuals who do not know that there are such treaties and do not have access to information to help them. There are also agreements in place in respect of National/Social Insurance. Even less is know by individuals about these.
Most responsible employers do try to help their employees but what about the self-employed, contractors and small businesses who do not have accountants to hand to research and give advice and assistance ?
Overseas workers should check with their employers to be sure they are being taxed correctly or consult an independent professional.
