SHON and Tax

[Robina]

Hi,

Some advice would be much appreciated.  We have just constructed a new bedroom in our adjoining stable and now I have to fill in the form "Impots Locaux" (form H1) and I am slightly confused about what figures to put in in section 41.  We got the Permis de Construire drawn up by an architect - so my personal understanding is not as comprehensive as it should be - but this shows the figures for the SHOB and the SHON after the work. 

Section 41a  of form H1 asks for the number of rooms used exclusively for habitation and what the suface area is.  It then goes on in section 41c to ask about garages and other elements incorporated in the house.  Can anyone tell me if the figure given for the SHON is the surface given for 41a or if it includes the surface in 41c as well.  If the latter presumably I have to do some calculation to fill the form in.[:(]

Best,
