Tax return after a month self employment?

greenchicken

Hope this is the right place to post - looking for some advice!

All my life I have had jobs that I pay tax for via PAYE. However I was made redundant in June and before starting a full time job in August I did 4 weeks of casual work where I was paid by submitting an invoice, and told I should sort out my own tax.

I therefore registered as self-employed, and then told HMRC when this period was over.

I now have no idea what I need to do in terms of my tax return. Do I need to do a whole return for just those weeks? What happens to my old and new PAYE jobs on the return?

I am really confused by the whole thing!

Any advice much appreciated.

I believe that if it's a single one-off payment that you received outside the PAYE system, you can just call the tax office, tell them about it (they might want proof) and they will adjust your tax code to suit. That's the best thing, though - call the tax office and ask them.
