Can someone explain this situation with pensions to me in very small words?
I have a private pension which I contribute to by direct debit each month. These payments are made after tax (my workplace takes tax out of my salary each month with PAYE, and I have a separate workplace pension). The private pension provider then adds an extra 20% of each payment into my fund, as tax relief. So I "get back" the tax I've paid on my private pension payments - so far, so good.
I've now started some side work on top of my job, and wanted to put the money made from this self-employed work directly into my private pension. I haven't paid tax on this side work money as yet - it's literally just come into my bank account. If I put this money into my pension (say, £30k) into my pension, the pension provider then automatically adds on an extra 20% to this - even though I haven't paid any tax on the side work money as yet. So I've effectively got £7.5k "free money" added to my pension. Now, obviously I have to pay that money back to HMRC! So I have to find £7.5k from my savings to pay my next tax return.
Is the above correct? Is there any way of telling the pension provider "I haven't paid tax on this money, so don't give me the extra 20%"?
All figures made up, btw - my side job is not that lucrative!
