Receiving State Pension from EU countries (e.g Belgium)

Is the pension received from Belgium and other EU states (not private pensions) taxable in the UK or in the State that pays the pension? In this case we are a married couple and are UK citizens and resident. We complete self assessments every year but were resident in Europe prior to 2016 . In our specific case only one of us receives the Belgian state pension, Do we need to declare that on a Belgian tax return or a UK self assessment form?

Hi
The Belgian state pension is not taxable in the UK under the Double Taxation Agreement.
Any private pension received will b e taxable here.
For other EU countries it depends on the double taxation agreement as to whether the state pension is liable in the UK.
