Does anyone know, within reasonable doubt, what the Portugal tax rate might be for an American citizen, after the end of their 10 year NHR regime status? This question applies to Social Security and IRA Distributions only and not regular income. Is there a special rate for Social Security and/or IRA Distributions? Is there a specific paragraph within Financas regulations that apply to these two categories, if known? Thank you for any accurate information that can be presented.
