Director Salary Optimisation 2025/26 — The Complete Strategy
For owner-managed limited company directors, taking a combination of salary and dividends remains the most tax-efficient extraction strategy. The optimal structure changed from April 2024 as the Employment Allowance became available to single-director companies for the first time, and dividend allowance reductions continued. The exact optimal figures change every April — always recalculate at the start of each new tax year.
The Core Principle
Salary is: (a) deductible from the company's taxable profits, reducing Corporation Tax; but (b) subject to both employee NI (Class 1, 8% above the primary threshold) and employer NI (13.8% above the secondary threshold). Dividends are: (a) not deductible from company profits — paid from post-tax profits; but (b) not subject to NI at all. The optimal mix minimises the combined NI + Corporation Tax burden.
Employment Allowance Change — April 2024
From April 2024, single-director companies (where the director is the sole employee) became eligible for the £5,000 Employment Allowance for the first time. This changed the optimal salary calculation:
- Without Employment Allowance: Optimal salary = Secondary Threshold (£9,100/year) — avoids employer NI entirely
- With Employment Allowance: Optimal salary = Personal Allowance (£12,570/year) — Employment Allowance absorbs employer NI on salaries between £9,100 and £12,570, while the full salary generates a Corporation Tax deduction and avoids employee NI (below the Primary Threshold)
Check whether your company qualifies for the Employment Allowance. Companies where the sole employee is a director who is the only employee generally qualify from April 2024. Companies connected to certain public bodies or where all employees are directors' family members may have different eligibility.
Dividend Allowance Reductions
The dividend allowance — dividend income received free of income tax — has been progressively reduced: £5,000 (pre-2018) → £2,000 (2018) → £1,000 (April 2023) → £500 (April 2024). Despite this reduction, dividends remain more efficient than salary for most director-shareholders because dividend tax rates (8.75% basic, 33.75% higher, 39.35% additional) are substantially lower than combined income tax and NI on equivalent salary income.
Corporation Tax Rates 2025/26
- Small profits rate: 19% on profits up to £50,000
- Marginal relief: Between £50,000 and £250,000
- Main rate: 25% on profits over £250,000
The salary deduction benefit increases as Corporation Tax rate increases. For a company at the 25% main rate, a £12,570 salary saves £3,142.50 in Corporation Tax. For a company at 19%, the saving is £2,388.30.
IR35 and Off-Payroll Working
If your company provides services to medium or large businesses, the client must assess whether the engagement is inside IR35. Inside IR35 means tax and NI are deducted by the client as if you were employed, making the director salary optimisation strategy largely irrelevant for that contract. Check your IR35 status before planning any salary and dividend strategy — the entire tax efficiency of a limited company structure depends on genuinely operating outside IR35.
Associated Companies and Profit Thresholds
If you control more than one company (associated companies), the Corporation Tax profit thresholds (£50,000 and £250,000) are divided between them. Two associated companies each reach the 25% main rate at £125,000 profit rather than £250,000. If you operate through multiple companies, factor this into salary optimisation calculations.
Annual Review and Tax Year Planning
The optimal director salary changes every April when new NI thresholds, Corporation Tax rates, and dividend allowance figures take effect. Review your salary and dividend strategy at the start of each new tax year. Key considerations: has the Employment Allowance eligibility changed? Has your company's profit level moved between Corporation Tax bands? Has your personal income from other sources changed? A strategy that was optimal in 2024/25 may not be optimal in 2025/26 without adjustment.
The optimal director salary strategy ultimately depends on your specific company's profit level, your personal tax position, your spouse's income (relevant for pension and Marriage Allowance planning), and your business plans. An accountant who understands all these factors comprehensively — not just the company accounts in isolation — will consistently produce better outcomes than applying generic rules. The cost of an annual tax planning meeting with a qualified accountant is typically recovered many times over in reduced tax liability and avoided errors.
Completing a thorough annual review of your director remuneration strategy — ideally in March before the new tax year begins — positions you to implement any changes from 6 April with full effect. The review should cover: current year profit level and expected CT rate; Employment Allowance eligibility confirmation; personal income from all sources; pension contribution opportunities; and whether the existing salary and dividend split remains optimal. Document the decisions made at a board meeting, produce a dividend voucher for any dividends declared, and ensure payroll is updated in time for the April payroll run. Good documentation and timely administration protects against any challenge to the tax treatment of your remuneration structure.
