Employer NI in Scotland 2026/27: Same Rules, Different Income Tax for Employees

Employer NI in Scotland: identical to the rest of the UK

Employer secondary Class 1 National Insurance is a reserved tax, meaning it is set at Westminster and applies identically across all four UK nations. Scottish employers pay 15% on employee earnings above the secondary threshold of £5,000 per year for 2026/27 — exactly the same rate and threshold as employers in England, Wales and Northern Ireland. There is no Scottish variation in employer NI, and no special payroll treatment is required for this calculation.

The Employment Allowance — which allows eligible employers to reduce their annual employer NI bill by up to £10,500 in 2026/27 — is equally available to Scottish employers who meet the eligibility criteria. A small Edinburgh business and a small London business with the same payroll size and structure receive exactly the same Employment Allowance relief. Eligibility rules, including the exclusion for companies where the sole paid worker is a director, apply UK-wide.

For a practical example: a Scottish employer with an employee on £35,000 per year pays £4,500 in employer NI annually — 15% of (£35,000 minus £5,000). This is precisely the same calculation that would apply in Birmingham or Cardiff. The employer cost calculator on this site produces correct Scottish employer NI figures without any regional adjustment because none is required.

What does change: Scottish income tax for employees

While employer NI is unchanged, employees based in Scotland are subject to Scottish income tax rates set by the Scottish Parliament. Scotland has six income tax bands ranging from the starter rate of 19% to the top rate of 48%, compared to three bands in the rest of the UK. This means a Scottish employee takes home less net pay than an equivalent rUK employee at the same gross salary above approximately £27,500.

The employer's payroll obligation is to apply the correct tax code for Scottish employees. HMRC issues S-prefixed tax codes (such as S1257L) for employees whose main residence is in Scotland. Payroll software must recognise this prefix and apply Scottish income tax calculations accordingly. If a Scottish employee is incorrectly processed on a standard 1257L code, they will pay too little income tax and face a debt to HMRC at year end.

When hiring in Scotland, employers should factor in that Scottish employees at mid-to-higher salaries may negotiate differently when comparing offers across the border. A £45,000 salary in Edinburgh produces approximately £60–£90 per month less take-home than the same salary in Manchester due to Scottish income tax. Transparent communication about this during offer discussions can reduce late-stage negotiation friction and avoid surprises for relocating employees.

Payroll compliance checklist for Scottish employees

For any employee who becomes Scottish resident — either a new hire from Scotland or an employee relocating — the employer must apply the S-prefix tax code notified by HMRC. This code change should be made in the payroll system from the effective date of Scottish residency. HMRC will communicate the new code via the PAYE coding notice system; employers should not change tax codes based on employee self-declaration alone but should wait for HMRC notification.

If an employee moves from Scotland to England or vice versa during the tax year, a new tax code will be issued by HMRC reflecting the change in residency. Employers who operate across multiple UK locations should ensure their payroll software is updated promptly when residency changes, as incorrectly applied codes create reconciliation issues at year end.

Employer NI calculations require no special treatment in Scotland — use the standard 15% above £5,000 as for all other employees. Pension auto-enrolment rules are also UK-wide and unchanged in Scotland. The only Scottish-specific payroll element is the S-prefix income tax code for employee PAYE purposes.

Frequently asked questions

How much does it cost to employ someone in the UK?

The true cost to employ someone in the UK is typically 15–20% above gross salary. At £30,000: employer NI £3,750 + pension £713 = approximately £34,463 per year. At £50,000: employer NI £6,750 + pension £1,313 = approximately £58,063 per year. Adding workplace overheads of £2,000–£5,000 can bring the total to 20–25% above the headline salary.

What is the employer NI rate for 2026/27?

For 2026/27, employer Class 1 National Insurance is charged at 15% on employee earnings above the secondary threshold of £5,000 per year (£96 per week, £416 per month).

What is Employment Allowance and who can claim it?

What is the total employer cost above salary?

Beyond salary, employer cost includes: employer NI (15% on earnings above £5,000), employer pension (minimum 3% of qualifying earnings between £6,240 and £50,270), and overheads such as equipment, software and workspace. For most UK salaries this adds 12–20% above headline pay. Use the inputs above to set your exact pension rate and overhead figure.

What changed for employers in April 2025?

Three changes took effect from 6 April 2025: the employer NI rate rose from 13.8% to 15%, the secondary threshold was cut from £9,100 to £5,000, and Employment Allowance increased from £5,000 to £10,500 with the eligibility cap removed. For a £30,000 salary, annual employer NI increased from approximately £2,884 to £3,750 — a rise of £866 per year.

How is employer NI different from employee NI?

Employer NI is a cost paid by the employer on top of gross salary — it does not reduce take-home pay. Employee NI is deducted from the employee's wages instead. For 2026/27, employees pay 8% on earnings between £12,570 and £50,270, then 2% above that. Employers pay 15% on all earnings above £5,000 with no upper cap. This calculator covers the employer side; for employee take-home pay see AfterTaxSalary.co.uk.

UK employer costs in 2026/27 are: gross salary, employer NI at 15% on earnings above £5,000, employer pension at minimum 3% of qualifying earnings (£6,240–£50,270), and any operational overheads such as equipment or software. For a £35,000 salary, statutory employer costs (NI + pension) add approximately £5,363/year before overheads.

How much do I cost my employer in the UK?

Your employer pays these on top of your salary; they are not deducted from your pay. Use this calculator to see the exact figure for your salary.

Is this a PAYE cost calculator for employers?

Yes. PAYE employer costs include employer NI — calculated at 15% above £5,000 for 2026/27 — plus the employer's auto-enrolment pension contribution. The full calculator models both alongside any overhead assumptions to give a total PAYE-basis employer spend per employee.

What is a cost to company (CTC) salary in the UK?
