Class 4 National Insurance calculations on self-employed income incorrect

Hi, I've just completed (but not submitted) my Self Assessment for the 22-23 tax year. My income is a combination of PAYE and self employment. From my PAYE income I have already paid over £4800 in National Insurance this year, therefore by Regulation 100 my self employed income should have NI levied at the 2.73% rate, but Self-Assessment is not taking my PAYE payments into account, and charging NI at 9.73% on my self-assessment income. How do I correct this so that the right NI amount is charged?

Hi
You will need to submit the tax return first.
Once it comes through to our systems it will be updated and an amended calculation will be issued.
Thankyou.
