Last updated: 12 July 2026. The UK has no special part-time tax regime — pay is hourly rate × hours, with the same £12,570 personal allowance and National Insurance rules as full-time. Because NI is charged per pay period, part-timers earning below the Primary Threshold (£1,048/month) pay £0 employee NI but still build a State Pension year if they earn above the Lower Earnings Limit (£6,708/yr). NMW is £12.71 (21+). Source: gov.uk — rates and thresholds 2026 to 2027.

iHow it is calculated
Part-time pay in the UK is simply your hourly rate × hours worked (or a full-time salary scaled to your contracted hours). The same deductions apply as for full-time: income tax at 20/40/45% above the £12,570 personal allowance, and employee National Insurance at 8% between the Primary Threshold and the Upper Earnings Limit. Earn below £1,048/month and your NI is £0 — but stay above the Lower Earnings Limit (£6,708/yr) to keep your State Pension qualifying year.
take-home = gross − income tax − National Insurance
At £12.71/hour (the 21+ minimum wage) for 20 hours/week, gross is about £1,101/month — just above the Primary Threshold, so a little NI is due, but well under the personal allowance so no income tax. Take-home is nearly the full gross. Drop to 15 hours/week and NI falls to £0, while you still earn a State Pension credit for the year.

?Frequently asked questions
Is part-time pay taxed differently in the UK?
No. There is no special part-time regime. Pay is your hourly rate times the hours you work, and the same income tax bands, £12,570 personal allowance and National Insurance rules apply as for full-time staff.
How is part-time pay calculated?
Either hourly rate × hours worked, or a full-time annual salary scaled down to your contracted hours. From the gross, income tax and employee National Insurance are deducted through PAYE to give your take-home.
Do part-time workers pay National Insurance?
Only on earnings above the Primary Threshold of £1,048 a month. Because NI is worked out per pay period, many part-timers earn below that and pay £0 employee National Insurance, even though income tax is worked out over the whole year.
What is the Primary Threshold?
It is the point at which employee National Insurance starts — £1,048 per month (£12,570 a year) for 2026/27. Below it you pay no employee NI; above it you pay 8% up to the Upper Earnings Limit.
Will I still get a State Pension if I earn below the threshold?
Yes, as long as you earn above the Lower Earnings Limit (£6,708 a year, about £559 a month). Earnings between the LEL and the Primary Threshold cost you no NI but still count as a qualifying year toward your State Pension.
What is the minimum wage for part-time work?
The same as for full-time. The National Minimum/Living Wage for workers aged 21 and over is £12.71 an hour in 2026/27. Part-time hours must be paid at least at your age-band rate.
Do part-timers get the full personal allowance?
Yes. The £12,570 personal allowance is annual and not reduced for part-time work. Many part-timers earn under it and so pay no income tax at all, keeping their full gross minus any National Insurance.
Do holiday and pension rights differ for part-time?
They are pro-rata, not reduced in principle. Part-timers accrue 5.6 weeks of statutory holiday scaled to their hours and, if they earn above the auto-enrolment trigger, are enrolled into a workplace pension the same as full-time staff.
Do I pay less tax overall working part-time?
Usually yes, because your total earnings are lower — you may stay within the personal allowance and below the Primary Threshold, so both income tax and NI can be zero. The effective rate on each pound, however, follows the same bands as full-time.
