Other 'posts' on this blog deal with the substance of this.
Consider an elderly couple who retired to France before 1998. We will call them Mr and Mrs. Briton. He is now over 80 and was a teacher.
How much do they lose out taking on board EU law?
The total they appear miss out on and/or have to find is 2627+344+1500 = 4471 euros. But note later- we need to take in their other pension - The State Retirement Pension, which is their only other income. Although taxable in France it is too little to attract more tax.
If EU law on health costs as it appears to be written was observed they would have no health costs. see note b/.
IF all their income were taxed in France then one has to include their joint State retirement pension (11640 euros) in the calculations of taxable income in France. The French Tax bill would be 1812 euros. This is 815 euros less than their existing UK tax bill. The amount they lose out on then has to be recalculated as 815+344+1500 = 2659 euros
So, if all were really fair for this elderly British couple they would have an extra 2659 euros a year to enjoy life.
When they retired the exchange rate between £ and France was very favourable and these financial matters were not particularly important. Since then the £ has collapsed and they are watching the centimes.
