Myself and my brother bought a house in 1998. Rented it to various tenants for 4 years. After 4 years in 2002 my brother bought me out. Settled with revenue for CGT and paid 4,000 euro. We never made returns for income from 1998 to 2002. Income was small as a lot of setup expenses and also interest on mortgage. Any advice as to what should we do as regards making a tax return for those years (1998 - 2002) ?
