For Cooperlola and Antonia: sorry I have only just picked up on these posts and did not reply sooner. I am far from being an expert, but my understanding is that early retirement occupational pensions (received before UK State pension age is reached) are only subject to the 0.5% Contribution Social Generalisée on the gross figure received; certainly this is what I have been charged for the last five years - (and I suspect is what you also have paid from your comments, Cooperlola). My recollection is that this reduced level of CSG for such pensions was the result of a case taken to the European Court - with which Sunday Driver (and perhaps Parsnips) was/were involved. However, I cannot support my recollection with any documentation, because when my previous hard disk "died", I lost lots of references/articles which I had bookmarked and can no longer quote "chapter and verse". However, I am sure Sunday Driver/Parsnips could confirm. If I am correct, only CRDS box 8TL would need to be completed with the gross pension figure - along with any other relevant figures of income such as UK interest, rent viagères etc - and no entry would be required, in respect of the gross pension, in any of the four CSG boxes. The situation changes, of course, when one or other of you/spouse reaches UK State pension age and obtains a form S1 (former E121), whereupon you cease to have any liability to CSG on pension income - as no longer "à la charge" of the social security system, courtesy of the S1 - and you become no longer liable to make CMU contributions. The whole thrust of boxes 8TQ/8TV/8TW/8TX confuses me, as they do not appear very relevant rates of CSG for UK immigrants/ex-pats; there is no mention of the 8.2% standard rate of CSG, which is levied on UK interest, rent viageres etc; there is also no provision on form 2047K for the third Social Charge viz the 4.8% Prélèvement Social et Contributions Additionnelles - which is levied on UK interest, rent viagères etc! Leaving taxpayers to determine themselves which rate of CSG is appropriate for particular sources/levels of income seems wholly inappropriate to me and is just asking for mistakes. In my own case, I have merely provided ALL the figures to the tax office, but asked what level of Social Charges should apply - and from what year - as it appears, from explanatory note 2041GG, that I may be exonerated completely from CSG on pension income, because of the level of our overall Revenue Fiscal de Reference (for the last couple of years). (Here was I fairly comfortable with my knowledge of tax return process - until this year)!
