PAYE and Self-employment

Hello there, I recently left a PAYE job and started a self-employment job. 1. Would the NI class 2 & 4 payment only start from date of self-employment (disregarding what I’ve already paid via PAYE) ? 2. Does my personal tax allowance for self-employment continue from my recent PAYE job this 2023/2024 tax year, or does it start at a new personal tax allowance (disregarding what I’ve already earned from my PAYE) Thank you in advance.

Hi,

1. It starts from your self employment. Any class 4 would take into account an adjustment for Class1 paid.  
2. Only 1 personal allowance of £12570 covers the income for the whole tax year.

Thank you.
