Just in the process of getting to grips with the new IMU tax, with the help of a very good site at the local comune, but it seems that the base figure of my cadastral value has gone uo by about 20%. I had a slight upward revision in 2006 when the renovations were finished, but I just wonder whether anyone can confirm the rough date of this latest hike. And point me in the direction of a site that works which provides accurate information on valuations.Another slight issue will be how to find out if, and by how much, the comune will uplift the final figure applied to the calculation. And of course, any advice on how to pay this would also be greatly appreciated. Hopefully the Agenzia Entrata will get something on line soon.Many thanks from a keen tax-payer!!
