Hi,
You can earn £12,570 tax free in the year, represented by the tax code 1257L. Whichever PAYE employment has this code allocated to it will have these tax free allowances applied to your income from that employment. Your other PAYE employment, and your self employment, will be charged at the basic rate of 20%.
However, depending on your income levels, your allowances can be split across your employments, and any unused allowances will be applied when you file your tax return. If you want to discuss the tax due on your specific income in more detai, please contact our Self Assessment team.
