How Quantity Surveyor Tax is Calculated 2025/26
UK quantity surveyors pay income tax under the standard PAYE system. For 2025/26, the personal allowance is £12,570 (no tax). Income from £12,571 to £50,270 is taxed at the basic rate of 20%, from £50,271 to £125,140 at the higher rate of 40%, and above £125,140 at the additional rate of 45%. Personal allowance is tapered above £100,000, creating an effective marginal rate of 60% between £100,000 and £125,140.
National Insurance for employees in 2025/26 is 8% on earnings between £12,570 and £50,270, and 2% on earnings above £50,270. NI funds the State Pension, NHS and contributory benefits.
Worked example for a quantity surveyor earning £45,000: Income tax = £6,036, National Insurance = £2,594, 5% pension contribution = £2,250. Take-home pay = £34,120 per year, equivalent to £2,843 per month or £656 per week.
Quantity Surveyor Salary Sacrifice & Pension Tax Relief
Pension contributions are one of the most tax-efficient ways for UK quantity surveyors to boost their long-term wealth. Under salary sacrifice, your gross pay is reduced before income tax and National Insurance are calculated, meaning every £1 you contribute saves both income tax (20% or 40%) AND National Insurance (8% or 2%).
Worked example: If you earn £45,000 as a quantity surveyor and contribute 8% (£3,600/year) via salary sacrifice, you save approximately £720 per year in tax and NI compared with making no pension contribution. Many employers also pass back their own NI saving (15% on the sacrificed amount), boosting your contribution further. Auto-enrolment minimum is 5% employee + 3% employer, but most financial planners suggest aiming for 12-15% total contributions for a comfortable retirement.
