Wise 'cashback' and Belgian & Spanish Tax
Like some other members, I have Wise accounts. Wise has recently started paying 'cashback' (interest) from which Belgian tax is being deducted at the rate of 30%. It is obligatory to declare this income on annual Spanish tax declarations, which, for me, means paying more tax on the this income at 37%, meaning the income is being taxed at a total of 67%. I have clicked on the Wise links to various Belgian tax forms in the hope of applying for an exemption from paying Belgian tax as a non-resident buy cannot understand them. Does anyone know of a Belgian tax assessor who can help me with this, although to be honest I think it might be easier to just opt out of the Wise 'cashback' system, having already had some skirmishes with the Hacienda in the past which took years to sort out.
