This is the second return that I've made since we moved here and I am pretty pleased that once again I have managed to complete the 8 or so pages in French and had them accepted by the authorities.
I think with even very limited French anyone moving here should with a bit of common sense be able to fill these out plus I have put together some notes on my Living in Brittany website which although fairly basic ie: relating to others in similar positions to ourselves being on old age pensions plus some private pensions and some income from investments should give anyone a good reference to start with.
The tax return is important to us as by proving our income to be below a certain level, and this is the only proof that is accepted, means that we get out Tax D'habitation reduced to zero and a hundred euro reduction on our Tax Fonciere. Tax D'habitation and Tax Fonciere together are the equivalent of house council tax or rates in the UK.
By doing some reading up on the rules I was also able to reclaim nearly 300 euros of tax that I had paid on a wood burner that we had installed last year, It is worth noting though that this has to be installed by a professional with a copy of the original paid invoice to enable this. This would also be reclaimable on other eco friendly installations such as cavity or roof insulation, double glazing etc.
