Tax efficiency for limited company contractors operates at multiple layers simultaneously. The salary-versus-dividends split is the headline decision but pension contributions, trivial benefits, electric company cars, Relevant Life Policies, and (where genuine) spouse dividend allocation each add increments. The compound effect across all available legitimate strategies can shift the effective tax rate by 5-8 percentage points compared to a contractor optimising only the salary/dividend split.
This guide covers the strategies that materially affect contractor take-home. Each is documented with the specific 2026 numbers and the rules that apply.
The dividend allowance has shrunk to £500
The dividend tax-free allowance was reduced from £2,000 to £1,000 in April 2023, then to £500 in April 2024. Most contractors with dividend income above £50,000 see the entire dividend stream taxed at 33.75% (higher rate) or 39.35% (additional rate). The traditional £2,000 dividend buffer is now largely gone.
The optimum salary and dividend split for 2025-26
For a contractor with profits sufficient to pay £80,000 in remuneration, the standard 2026 structure:
- 1Salary: £12,570 (the personal allowance threshold). Uses the personal allowance, generates a qualifying NI year for State Pension, triggers minimal income tax.
- 2Employer NI on the £7,570 of salary above the £5,000 secondary threshold: ~£1,135 at 15%.
- 3Dividends: £67,430 from post-tax profits.
- 4Personal income tax position: £500 dividend allowance, then £37,200 at 8.75% basic rate, then remaining £29,730 at 33.75% higher rate (above £50,270 personal income).
The total personal income tax on this structure is around £13,250. Combined with £1,135 of Employer NI plus the underlying corporation tax on the company profit, the total effective tax burden is approximately 32-34% on the £80,000 of personal extraction. Substantially better than the equivalent salary route.
Company pension contributions, the highest-leverage extraction
Company pension contributions are the most tax-efficient form of director extraction:
- Tax-deductible against corporation tax (saves up to 25%).
- Tax-free for the director (no income tax, no NI on the way in).
- Grows tax-free inside the pension.
- On drawdown: 25% tax-free; remainder taxed as personal income at retirement-rate income tax.
Annual allowance: £60,000 for 2025-26 (tapered for high earners with adjusted income above £260,000). Carry-forward of unused allowance from the prior 3 years allows catch-up contributions up to £180,000+ in some years. For a contractor in a high-profit year, accelerating pension contributions can be the single largest legitimate tax-saving move available.
Electric vehicles via salary sacrifice
Electric company cars currently offer the most favourable benefit-in-kind treatment of any major employee benefit:
- BIK rate for fully electric vehicles: 3% of list price for 2025-26 (rising to 4% in 2026-27 and 5% in 2027-28).
- For a £40,000 EV, BIK is £1,200; income tax on that is £240-£480 per year.
- Company gets 100% First Year Allowance on the EV purchase (full corporation tax deduction in the year of acquisition).
- Full corporation tax deduction on running costs (insurance, servicing, electricity for charging at the company's expense).
- Salary sacrifice arrangement makes the BIK net cost even lower because the salary reduction itself is tax-free.
For a contractor extracting £80,000+ via salary and dividends, redirecting £4,000-£8,000 of that into an EV salary sacrifice produces a personal-use vehicle at materially lower net cost than buying privately.
Income splitting with spouses, Section 660A
A contractor whose company is owned jointly with a spouse can pay dividends to the spouse, using the spouse's personal allowance, dividend allowance, and basic-rate band. The mechanics need to satisfy Section 660A of the Income and Corporation Taxes Act 1988 (the "settlements" legislation). HMRC challenges arrangements where:
- The shares were initially gifted by the income-earning spouse without genuine commercial substance.
- The shares carry no economic risk (preference shares with cumulative dividend rights, for example).
- The arrangement is purely a tax mechanism with no other commercial reason.
Genuine joint shareholding from incorporation, with ordinary shares that carry full economic risk, is generally accepted. The Arctic Systems case (2007) established the broad principle. Specific advice for each case is essential.
Trivial benefits and the £150 staff event allowance
A "trivial benefit" up to £50 per occasion (capped at £300 per director per year) is fully tax-deductible for the company and tax-free for the recipient. Examples: birthday gifts, gift vouchers, occasional restaurant meals not connected to work. Plus the £150 per head per year for a single annual staff event (Christmas party, summer event), which is a separate allowance. Both are commonly missed by contractors.
Relevant Life Policies for contractors
A Relevant Life Policy (RLP) is a tax-efficient life insurance arrangement structured for limited company directors:
- Premiums paid by the company are corporation-tax deductible.
- Premiums are not treated as a benefit-in-kind (so no income tax or NI for the director).
- Death benefit is paid to a discretionary trust outside the deceased's estate (no IHT impact).
- Compared to personal life insurance: the company premium is effectively at corporation tax rate (saves up to 25%) versus the personal premium at full income tax rate.
For a contractor with substantial life cover requirements, RLP delivers materially lower cost than personal life insurance. Setup is straightforward through specialist insurance brokers familiar with the structure.
