PAYE and self employed

I am currently working as a supply teacher and tutor and so I have multiple income streams, the majority are PAYE but for one company I am invoiced. I understand that for any earnings over £1000 I will have to complete a self-assessment. This income is for the tax year 2024/25 so I am I right in understanding that the deadline for registering for self-assessment is October 2025 and I would have to complete the self-assessment by 31st January 2026? many thanks

Hi annac,

Hi 
You are correct - you need to register for Self Assessment by October 5th 2025.
