Orthodontist Salary UK 2026/27: How Take-Home Pay Is Calculated After Tax, NI and Pension

Understanding Orthodontist Salary and Take-Home Pay

If you're researching an orthodontist salary in the UK, you'll want to know not just the gross figure but how much actually lands in your bank account each month. Orthodontists are specialist dentists who have completed additional postgraduate training, and their pay reflects that expertise. This article explains how take-home pay is calculated for orthodontists in 2026/27, covering income tax, National Insurance, NHS pension contributions and student loan deductions.

Gross Salary Ranges for Orthodontists

Orthodontists work in the NHS, private practice, or both. For NHS salaried roles, orthodontists are typically employed on the consultant pay scale. According to the After Tax Salary dentist pay guide, NHS dental consultants earn between £93,666 and £126,281 gross per year in 2026/27. Foundation dentists and core trainees start at around £35,799. Salaried staff grade dentists earn approximately £50,971.

Private orthodontist earnings vary widely and are not captured in official NHS data. The NHS Digital dental earnings estimates for self-employed dentists show a 6.1% increase in taxable income in 2024/25, but that covers all dentists, not orthodontists specifically.

How Take-Home Pay Is Calculated

Your take-home pay is your gross salary minus:

• Income Tax – based on your total taxable income
• National Insurance (NI) – Class 1 for employees, Class 4 for self-employed
• Pension contributions – if you're in the NHS Pension Scheme
• Student loan repayments – if applicable

Income Tax 2026/27 (England, Wales, Northern Ireland)

Income band	Tax rate
Up to £12,570	0% (Personal Allowance)
£12,571 – £50,270	20% (Basic rate)
£50,271 – £125,140	40% (Higher rate)
Above £125,140	45% (Additional rate)

An orthodontist earning £100,000 would pay 20% on the first £37,700 above the Personal Allowance, then 40% on the next £49,730, and lose some Personal Allowance (taper).

National Insurance 2026/27

Earnings band	Employee NI rate
Up to £12,570	0%
£12,570 – £50,270	8%
Above £50,270	2%

For an orthodontist earning £100,000, NI would be 8% on £37,700 and 2% on £49,730, totalling about £4,011.

NHS Pension Contributions

If you're an NHS employee, you must contribute to the NHS Pension Scheme. Rates for 2026/27 are tiered:

Salary band	Employee rate
Up to £13,259	5.1%
£13,260 – £26,831	5.7%
£26,832 – £32,691	8.3%
£32,692 – £49,078	9.8%
£49,079 – £62,924	10.7%
Above £62,924	12.5%

An orthodontist on £100,000 would pay 12.5% – that's £12,500 a year into the pension, reducing take-home pay significantly.

Student Loan Repayments

Orthodontists with student loans (Plan 1, Plan 2, or Plan 5) repay 9% of income above the threshold. For Plan 2 (post-2012), the threshold is £27,295. On £100,000, that's an extra £6,544 per year deducted.

Example Take-Home Calculation for an NHS Orthodontist

Let's take an orthodontist on the bottom of the consultant scale: £93,666 gross.

Deduction	Amount
Gross salary	£93,666
Personal Allowance	(£12,570)
Taxable at 20%	(£37,700 × 20%) = £7,540
Taxable at 40%	(£43,396 × 40%) = £17,358
Total Income Tax	£24,898
Employee NI (8% on £37,700 + 2% on £43,396)	£3,884
NHS Pension (12.5% of £93,666)	£11,708
Student Loan (Plan 2, 9% of £66,371)	£5,973
Total deductions	£46,463
Take-home pay	£47,203

That's about £3,933 per month. Without student loan and pension, take-home would be around £64,884 per year (as per aftertax.org.uk).

Scotland Differences

Orthodontists working in Scotland face different income tax bands. Scotland uses:

• Starter rate: 19% on £12,571–£14,876
• Basic rate: 20% on £14,877–£26,561
• Intermediate rate: 21% on £26,562–£43,662
• Higher rate: 42% on £43,663–£75,000
• Top rate: 48% on above £75,000 (note: different from England's 45% above £125,140)

An orthodontist earning £100,000 in Scotland would pay more tax than in England, reducing take-home pay. NHS pay scales in Scotland are also different (generally higher for lower bands), but the tax effect is the main factor.

Private Practice Orthodontists

Self-employed orthodontists pay Class 4 National Insurance (6% on profits £12,570–£50,270, 2% above) and no compulsory Class 2 since April 2024. They can choose their pension contributions and deduct business expenses. Earnings vary hugely; no official median exists for orthodontists specifically.
