7. In February 2018, Miss S sent HMRC a digital change of circumstances stating she had started a new job in January. This did not contain information about any increase in her household income.
8. In March 2018, Miss S sent a further digital change of circumstances advising that her income had reduced to £22,001 from £29,363. HMRC sent a revised award notice two days later.
9. In July 2018, HMRC received Miss S’s tax credit renewal which indicated a household income of £23,000 and four days later it issued her award notice for the 2018/19 tax year. This indicated that she was entitled, based on the information it held, to Child Tax Credit totalling £6,459.81.
10. In April 2019, HMRC issued a final declaration and asked Miss S to confirm her household income for the 2018/19 tax year. Miss S submitted a digital change of circumstances on 30 July 2019 indicating that her household income for that year was actually £42,680.
11. In September 2019, HMRC issued a finalised award notice for the 2018/19 tax year based on the most recent household income of £42,680. This stated that she had not been entitled to Child Tax Credit and had, therefore, received an overpayment of £6,459.81.
12. Miss S called HMRC in January 2020 to discuss the overpayment. HMRC explained that this was due to the increased household income it had been unaware of. Miss S and HMRC agreed a repayment plan that day.
13. In February 2020, Miss S disputed the overpayment as she said she called HMRC in January 2018 to inform it of her increased household income.
14. HMRC completed its consideration of her dispute on 18 February and called to advise that the amount remained recoverable. It explained that she had not met her responsibilities as set out in Code of Practice 26.
15. In April 2020, HMRC withdrew her Child Tax Credit for the 2019/20 tax year, but as she had already received a payment of £122.33, this became an additional overpayment.
16. On 5 September, Miss S disputed the overpayment again and stated she had evidence she had called HMRC to notify it of her change in income that it had failed to act on at the time. This led to the overpayment.
17. On 15 September, HMRC responded advising she was out of time to dispute the overpayment further as she had to do so within 30 days of its February decision.
18. On 26 September, Miss S contacted HMRC to again dispute the overpayment and said this was new evidence it needed to review that had not been considered before. She explained it had been difficult to obtain until that point.
19. On 29 September, HMRC again refused to consider the dispute as she was out of time.
20. On 1 October, Miss S submitted a complaint to HMRC stating she had written twice and submitted new evidence, but this had not been considered. She reiterated that she had called HMRC to update her information and HMRC had not acted on this information.
21. On 6 October, HMRC responded stating it had no details of her contacting them during the 2018/19 tax year regarding an increased household income. It asked for a copy of her phone bill to review possible dates of contact.
22. On 8 January 2021, Miss S complained further and provided a copy of her phone bill from February, March, and April 2018. She highlighted calls made to 0300 200 3300 in March and April and requested it review this evidence.
23. On 14 January, HMRC issued its response stating it was unable to locate the call dated March 2018. It explained that the overpayment remained recoverable as she did not notify it that her income was wrong following the July 2018 award notice.
24. Miss S contacted the Adjudicator’s Office to complain about HMRC’s actions. It did not uphold her complaint as it felt the evidence suggested she had not complied with Code of Practice 26.
