Hello, I’ve recently changed jobs and therefore wish to complete a self assessment to process my SIPP payments to ensure I pay the correct tax. This is for the tax year 24-25. What is the deadline for registering for this? I couldn’t work out if the 5th October is for this tax year, or the tax year 23-24. Thanks

Hello, In addition to an employee pension I make contributions to, I also invest money in a SIPP. Will HMRC be notified automatically of this and adjust my income tax calculations automatically? Thanks
