I have been in receipt of a taxable social welfare payment for a number of years.
It was discovered this year that I had been underpaid all along.
There were arrears of approx 10,000 due which were paid in 2025.
If all 10k is included in my 2025 tax return it will be taxable whereas I had unused tax credits for each of the previous years in which it should have been paid.
Can I include only the portion which should have been paid in 2025 in my 2025 tax return and redo my previous returns or is it just "tough luck"? If I can, do I need a statement from Social Welfare detailing which years or can I calculate it myself?
Also, why do Social Welfare just say: This is your payment, appeal if you want rather than detailing where they got their figures so that you can see whether you should appeal? In my case it would have been immediately obvious that they were incorrect and I really could have done with the money at the time (one child was omitted from qualified child allowance for years).
Thanks as always for any info.
