self assessment calculation

My husbands 2023-2024 assessment is showing first and second payments of £582.20 and then a balancing payment of £1164.40 which totals £2328.80 to pay before 31/1/25, could this be a mistake

Hi EunBen01,
We would need to access your husbands record to review to see if the statement is correct.
