Hi, I live in Spain and I have a house a few years that was used by family to live in and I also sometimes stay when I visit Ireland. I have just realised that in Spain we have to fill out a 720 module and I never did this as never heard of it and because not rented I never looked into it. In the last few months due to illness I decided to rent it and registered it for rent and registered with revenue etc and rtb.. but I am nervous now as I have never heard of the 720 module until now. Has anyone had a similar issue and not done it but done it later and what happened? Spain gave massive fines before for this and I know in 2022 this changed as they had to change this as fines were 5000 euros- 10,000 euros etc and some went to 150% fines which went to the eu court.. I am just reading up on this now..
