My mam paid 17,000 in fair deal scheme for nursing home fees for my dad. She did not apply for the loan on the home, she just paid the fair deal amount. Dad was in the nursing home for a few months in 2024. Mam applied for tax back for 2024 but because she hadn't paid too much tax she didn't get a huge amount back. Can she claim these fees against tax paid in previous years? So could she complete a tax return for 2023 for example stating the fair deal was paid in 2024. Seems like tax office told her she could but seems wrong to me?
