Pension Contribution Tax Refund Added - which financial year?

I have just (26th Feb 2025, during the 24/25 tax year) added some money to my SIPP. I am told that the 25% tax topup for that contribution will be paid into the SIPP in 6-8 weeks. If that repayment from HMRC arrives in my SIPP account in, say, mid April (during the 25/26 tax year), is the tax deemed to have come from the 24/25 tax year, or the 25/26 tax year for self-assessment purposes? And does it count against the £60k pension contribution limit for 24/25, or 25/26?

I have the exact same question. If anyone could contribute would be really appreciated. Thanks.

I'm fairly sure the date that matters is the always the date of the original contribution reached the scheme, as Self Assessment doesn't seem capable to representing a net contribution in one year and its relief in the following year, and nothing seems to be written anywhere about that kind of split treatment being a thing. However since I've never been able to find anything online that outright confirmed this, when this mattered to me, I chose to ask the SIPP provider to confirm the tax treatment of the particular payment, so I had something in writing - which they did, attributing the relief to the tax year of the original contribution.

Hi,
It will be the 2024 to 2025 tax year as it is when your actual contribution is made.
Yes, the tax relief counts towards the 60k limit for 2024 to 2025.
Thank you.

Thank you - fabulous!
