Paye employed in the 40% tax bracket + freelance all going into my sipp

Hi is there a way to put all my freelance into my sipp in order to increase my pension contributions and avoid paying any tax at all on it? I make enough from my main job so the freelance work id love to have all in my Sipp Whats the best way to this?

Hi Amy R,
HMRC cannot advise you on this as this is financial advise which we are not authorised to give.
Thank you.

Do you have any recommendations?

Hi Amy R,
You will need to register for self assesment to declare the £15910. For pension relief, please see additional guidance at:
Tax on your private pension contributions.
Thank you.

Hi HMRC Admin 21, Im super confused now. Can you clairfy this? I have a paye job making 58k. This is taxed already in my pay check. I made 15k as a sole trader and put this full 15k into my sipp. I need to call HMRC to do declare this? I can't just do a self assessement?

Hi Amy R,
You need to do a tax return for this in order to declare both - Self Assessment tax returns.
Thank you.

Ok thanks!
