Hi,
If you are confident that you know how much tax you will owe by the end of the 2024 to 2025 tax year, you can reduce your payments on account accordingly. You can do this through your personal tax account online, or by contacting our Self Assessment team.
Personal tax account: sign in or set up
Self Assessment: general enquiries
The code used by your employer should be operated on a Month 1 basis, which ensures that you are neither overtaxed, nor use the tax free allowances that you may have already applied during your self employment. If your code is not issued on this basis, or you feel you are being overtaxed, contact us using the method above and we can review your code.
Thank you.
