Tax Self Assessment and Pension question - when you have a SIPP and an employer pension

[MustardAndCustard]

I'm doing a self assessment form as I put a lump sum into my SIPP. Can anyone help me understand what I include on the form? I've googled and I'm not much clearer!

I pay into a pension via my employer. This is via salary sacrifice.
I also have a SIPP where a lot of my old employer pensions are consolidated. Last year I also put a lump sum into this SIPP.

In the section on self assessment about paying into registered pension schemes (Payments to registered pension schemes (also known as PPR) where basic rate tax relief will be claimed by your pension provider (called 'relief at source'). Enter the payments and basic rate tax:) do I put

• only the lump sum amount OR
• the lump sum amount AND my personal contributions to my employer pension.

The next question on the form is about 'one off payments' included, so I am expecting to put the lump sum payment in there.

Thanks in advance for any insight!

No need to put in your work pension contribution as this is via salary sacrifice

So only put in the SIPP lump sum amount into your tax return. This needs to be entered 'gross' - so include both the cash amount you paid in plus the tax releif claimed by the SIPP provider. So if you paid in £8000 in cash, the provider would have claimed £2000 in tax relief, so put £10,000 in the tax return
