Part time second job tax

Hi Keman,
Hi, the standard personal allowance this tax year is 12570, this is shown on your payslip under the tax code 1257L, what this means is that every tax month from April 2024 to March 2025 you can earn up to £1047.50 before any tax will be deducted. And any unused amount is carried forward to the follwing month, so if you earned say 547.50 in April 2024 then you will have 500 spare tax free earning that will be rolled over to May 2024 pay, so that month you will then be able to earn £1547.50 before any tax will be deducted. This  carries on like this for the full tax year.
If you have 2 employments, usually the main employer has the tax code 1257L and your second operates a BR code,  20% tax, on all earnings there. You can, if you know what you income will be at both sources, ask HMRC to split your allowances between both sources ,or after the tax year has ended we will auto review your record and if you have any unused personal allowance we will review if any tax repayment is due.
Thank you.

Hi binczekoladen,
To review your tax codes for both jobs please contact HMRC here:
Income Tax: general enquiries
You can then request your tax code be split between your two jobs/employer. 
Thank you.
