Mandatory Class 2 NI was abolished in April 2024 — with profits above the £7,105 Small Profits Threshold you get the State Pension credit automatically.
What to set aside for the tax bill
Nothing is deducted from your invoices at source, so the discipline that matters is moving £53 a month — about 4.2% of everything you earn — into a separate account the day you get paid.
Because the bill on £15,000 of profit is £632, it is below the £1,000 payments-on-account threshold, so you simply pay it in one go by 31 January after the tax year ends.
