Pro rata means your salary is adjusted proportionally. Working 3 days out of 5 = 60% of the full-time equivalent (FTE) salary. Tax and NI are calculated on the pro rata amount, which often means a lower tax rate than full-time.
Part-Time Tax on £24,000
Part-time workers are taxed exactly the same way as full-time workers — there is no separate part-time tax system. If your part-time salary is £24,000 per year, your tax and NI calculations are identical to a full-time worker on the same annual salary. The key difference is that part-time workers are more likely to earn below certain thresholds, which can affect tax efficiency.
Part-Time Benefits and Pension
Part-time workers have the same employment rights as full-time workers on a pro-rata basis, including holiday entitlement (minimum 5.6 weeks, pro-rated), pension auto-enrolment (if earning over £10,000/year and aged 22-66), statutory sick pay, and redundancy rights after 2 years of service. On £24,000, you qualify for pension auto-enrolment. Your employer must contribute a minimum of 3% of qualifying earnings.
Multiple Part-Time Jobs
If you hold multiple part-time jobs, each employer deducts tax independently. Your Personal Allowance (£12,570) should only be applied to one job — your main employment. Additional jobs should use tax code BR (20% on all earnings). If your tax codes are wrong across multiple jobs, you may overpay or underpay tax during the year. Check your tax codes through your HMRC Personal Tax Account to ensure they are correct. See £24,000 salary after tax for the complete breakdown.
