Private Pension contribution for self-employed

Dear HRMC, I am a self-employed people (working as a sole trader) for 2023/24 and my total income (net expense) is around £81K which I shall become a higher rate tax payer. I am considering to join a private person pension scheme since I want to pay fewer tax. If I contribute £30K to a private pension, will this reduce my total taxable income to £50K? Will I get £30K tax relief which can be reflected on self assessment return? Such that I don't need to pay for 40% portion
