For six years have lived in self build (self financed) with full planning permission etc on 1/4 acre site that is owned by farming parent. Have no idea what site is worth or house (but would guess site less than 40k and house really 200K to 250K). Sibling did same thing after me but nows wants to transfer site into own name and after visiting solictor realise there is trouble ahead. The solictor advised immediate action as next budget looks like there will be big changes around this area. I have read other posts here (and other tax/legal websites) around stamp duty, CAT and CGT and their was only one post ideally reguarding my issue and no one had answered it. My questions are 1) to register site what tax is payable 2) i have no intention of moving or selling etc so should I just let things lie as they are (implications of this). Any advice is welome. Thank You for your time in advance.
