Workplace Pension

To utilise my annual allowance, a large pension contribution was deducted from my payslip in March 2023 (2023/24) and then again in April 2023 (2024/25). The pension provider has allocated the two payments into 2024/25 which I believe is incorrect for tax purposes. The pension provider works on payment date as opposed to payslip date and therefore not aligned with HMRC. In terms of the the tax return, the March pension contribution should be included on my 2023/24 tax return and April contribution in 2024/25. Is this correct?

Hi.
You can see guidance below, as the method of payment determines the date:
