Belgian-Spanish Double Taxation Treaty
The 2009 Belgian-Spanish Double Taxation Treaty (Verdrag ter voorkoming van dubbele belasting) prevents Belgian tax residents from being taxed twice on the same income or capital gains in both countries. For Spanish tax residents, worldwide income is taxed in Spain. However, specific assets like real estate are generally taxed where they are located. Wealth tax (Impuesto sobre el Patrimonio) and inheritance tax (Impuesto sobre Sucesiones y Donaciones) are governed by separate rules and can apply in Spain depending on residency and asset location.
