Optimal Director Salary 2025/26 Tax Year

Every year, directors of small limited companies face the same question: how much salary should I pay myself? Get it right and you'll save thousands in tax. Get it wrong and you'll hand money to HMRC that you didn't need to.

The answer depends on National Insurance thresholds, the Employment Allowance, corporation tax rates, and how much profit your company makes. This guide breaks down the exact numbers for the 2025/26 tax year (6 April 2025 to 5 April 2026) so you can set the optimal salary from day one.

Why Not Just Pay Yourself the Minimum?

Many directors default to either paying nothing or paying the bare minimum. But there's a sweet spot where salary actually saves you money overall — because salary is a deductible business expense that reduces your corporation tax bill.

The trade-off is:

Salary attracts National Insurance Contributions (NICs) but reduces corporation tax
Dividends don't attract NICs but are paid from post-tax profits
The optimal salary is the point where the corporation tax saving outweighs the NIC cost

Key Thresholds for 2025/26

Before we calculate anything, here are the numbers you need:

Threshold	Annual amount	Weekly equivalent
Lower Earnings Limit (LEL)	£6,396	£123
Primary Threshold (employee NICs)	£12,570	£242
Secondary Threshold (employer NICs)	£5,000	£96
Employment Allowance	£10,500	—
Personal Allowance	£12,570	—

National Insurance rates (2025/26)

Employee (Class 1 primary): 8% on earnings between £12,570 and £50,270
Employer (Class 1 secondary): 15% on earnings above £5,000
Class 2 NICs (self-employed): Not relevant for directors taking salary
Class 3 voluntary: £17.75 per week (for reference)

Scenario 1: No Employment Allowance (Single Director, No Other Employees)

Most single-director companies with no other employees can now claim the Employment Allowance since the rule change in April 2022 — but only if the director is not the sole employee AND no more than 50% of the work involves directorial duties. In practice, many single-director companies cannot claim it.

If you cannot claim the Employment Allowance:

Option A: Salary at the Primary Threshold — £12,570

At this level:

Employee NICs: £0 (salary equals the Primary Threshold exactly)
Employer NICs: (£12,570 − £5,000) × 15% = £1,135.50
Income tax: £0 (salary equals the Personal Allowance)
Corporation tax saved: (£12,570 + £1,135.50) × 25% = £3,426.38 (at main rate)

Net benefit vs. no salary: £3,426.38 − £1,135.50 = £2,290.88

Option B: Salary at the Secondary Threshold — £5,000

At this level:

Employee NICs: £0 (below Primary Threshold)
Employer NICs: £0 (salary equals the Secondary Threshold exactly)
Income tax: £0 (well below Personal Allowance)
Corporation tax saved: £5,000 × 25% = £1,250

Net benefit vs. no salary: £1,250

Option C: Salary just below the Primary Threshold — £12,570

This is the same as Option A in numbers, but worth noting: there's no employee NIC at £12,570 because the Primary Threshold is exactly £12,570. You don't start paying employee NICs until you exceed it.

The verdict (no Employment Allowance)

£12,570 wins. Even with £1,135.50 in employer NICs, the corporation tax saving of £3,426.38 produces a net benefit of £2,290.88 — almost double the benefit of the £5,000 option.

However, if your company pays the small profits rate (19%), the calculation changes:

CT saved at 19%: (£12,570 + £1,135.50) × 19% = £2,604.05
Net benefit: £2,604.05 − £1,135.50 = £1,468.55

Still better than £5,000 at 19% (which saves only £950), so £12,570 remains optimal at both rates.

Scenario 2: Employment Allowance Available

If your company has at least one other employee (not just the director) or the director's duties are less than 50% directorial, you may qualify for the £10,500 Employment Allowance, which offsets employer NICs.

With the Employment Allowance:

Salary at the Primary Threshold — £12,570

Employee NICs: £0
Employer NICs: £1,135.50 — but offset by Employment Allowance → £0 actually payable
Income tax: £0
Corporation tax saved: (£12,570 + £0) × 25% = £3,142.50

Net benefit: £3,142.50 (employer NICs covered by Employment Allowance)

Could you go higher?

With the Employment Allowance covering employer NICs, you might consider paying more than £12,570. But above the Primary Threshold, employee NICs kick in at 8%:

Salary at £20,000:

Employee NICs: (£20,000 − £12,570) × 8% = £594.40
Employer NICs: (£20,000 − £5,000) × 15% = £2,250 — offset by EA → £0
Income tax: (£20,000 − £12,570) × 20% = £1,486
CT saved: £20,000 × 25% = £5,000

Total taxes on the extra £7,430: £594.40 + £1,486 = £2,080.40 CT saving on extra £7,430: £7,430 × 25% = £1,857.50

The extra salary costs more in tax than it saves in CT. So even with the Employment Allowance, £12,570 remains the optimal level.

Summary: The Optimal Salary for 2025/26

Situation	Optimal salary	Employer NICs payable	Net tax saving
No Employment Allowance, 25% CT rate	£12,570	£1,135.50	~£2,291
No Employment Allowance, 19% CT rate	£12,570	£1,135.50	~£1,469
Employment Allowance available	£12,570	£0 (covered by EA)	~£3,143
No qualifying NI record needed	£12,570	Varies	Best overall

The answer in almost every scenario: pay yourself £12,570.

This is the sweet spot — it uses your full Personal Allowance, avoids employee NICs, and generates a meaningful corporation tax deduction.

What About Your State Pension?

To qualify for a year of State Pension, you need to earn above the Lower Earnings Limit (LEL) of £6,396 per year. At a salary of £12,570, you're comfortably above this — so you'll accrue a qualifying year for State Pension purposes.

If you were considering paying at the old Secondary Threshold (£5,000), note that this is below the LEL. You would not accrue a State Pension qualifying year at £5,000.

This is another reason £12,570 is the preferred option — it protects your State Pension entitlement.

How to Set Up Your Director's Salary

Payroll registration

Even if you're only paying yourself, you need to register for PAYE with HMRC and run payroll. Here's the typical setup:

Register for PAYE via HMRC's online service
Set up monthly payroll — pay yourself £1,047.50 per month (£12,570 ÷ 12)
Submit RTI (Real Time Information) returns — an FPS (Full Payment Submission) each month
Pay any employer NICs quarterly or monthly to HMRC

Tax code

Your tax code should be 1257L for 2025/26 (assuming you have one employment and no adjustments). If you have multiple income sources, HMRC may split your Personal Allowance — check your coding notice.

Directors' NIC calculation

Directors have an annual earnings period for NIC purposes, which means NICs are calculated on total annual earnings, not month by month. This works in your favour: even if you pay yourself irregularly, the annual threshold applies.

Taking the Rest as Dividends

Once you've set your salary at £12,570, the rest of your income should typically come as dividends. Here's why:

Dividends don't attract NICs (employee or employer)
The first £500 of dividends is tax-free (the dividend allowance for 2025/26)
Basic rate dividend tax is 8.75% — much lower than the combined income tax + NICs on salary above the threshold

Example: Total extraction of £50,000

Component	Amount	Tax payable
Salary	£12,570	£0 income tax, £0 employee NICs
Dividends (within basic rate)	£37,430	£500 at 0%, £36,930 at 8.75% = £3,231
Employer NICs on salary	—	£1,135.50 (or £0 with EA)
Total personal tax	—	£3,231

Compare this to taking £50,000 as pure salary:

Component	Amount	Tax payable
Salary	£50,000	£7,486 income tax
Employee NICs	—	£2,994.40
Employer NICs	—	£6,750
Total tax	—	£17,230.40

The salary + dividends approach saves over £12,800 compared to pure salary. That's the power of structuring your extraction correctly.

Common Mistakes to Avoid

1. Paying no salary at all

You miss out on the corporation tax deduction and don't accrue State Pension qualifying years. Even at the small profits rate, a £12,570 salary saves over £1,400 in CT.

2. Paying above the Personal Allowance

Every pound above £12,570 attracts income tax at 20% and employee NICs at 8%, plus employer NICs at 15%. The combined cost exceeds the CT saving.

3. Forgetting to run payroll

HMRC requires RTI submissions even for single-director payrolls. Late filing can trigger penalties. Set up payroll before your first salary payment.

4. Not checking the Employment Allowance eligibility

If you qualify, you save £1,135.50 on employer NICs — but you must claim it through your payroll software. It doesn't apply automatically.

5. Ignoring other income

If you have income from another employment or pension, your Personal Allowance may already be used. Paying yourself £12,570 when your allowance is allocated elsewhere means you'll owe income tax.

FAQ

What is the most tax-efficient salary for a director in 2025/26?

£12,570 per year (£1,047.50 per month). This uses your full Personal Allowance, avoids employee NICs, and creates a corporation tax-deductible expense that saves between £1,469 and £3,143 depending on your CT rate and Employment Allowance eligibility.

Should I pay myself a salary or just take dividends?

Both. Pay a salary of £12,570 to get the CT deduction and State Pension credit, then take remaining profits as dividends. Dividends are taxed at lower rates (8.75% basic, 33.75% higher) and don't attract National Insurance.

Can a single-director company claim the Employment Allowance?

Possibly, but it depends on your duties. Since April 2022, the exclusion applies only where the director is the sole employee and more than 50% of their work is directorial. If you do operational work (not just board duties), you may qualify — but check with HMRC or your payroll software.

Do I need to register for PAYE to pay myself a salary?

Yes. Even if you're the only director and paying below the tax/NIC thresholds, you must register for PAYE and submit RTI returns if you're paying any salary. You can register online through HMRC's government gateway.

What happens if I pay myself more than £12,570?

You'll start paying employee NICs at 8% and income tax at 20% on every pound above £12,570. Combined with employer NICs at 15%, the total tax cost exceeds the corporation tax saving — making it less efficient than taking the extra as dividends.

Does my director salary count towards my State Pension?

Yes, provided your salary exceeds the Lower Earnings Limit (£6,396 for 2025/26). At £12,570, you're well above this threshold and will accrue a full qualifying year towards your State Pension entitlement.
