Running a limited company offers real flexibility — but with corporation tax now sitting between 19% and 25%, proactive strategies are essential if you want to retain more of your earnings in 2026. Most business owners are leaving thousands on the table every year, completely legally. Here's how to change that.

1. Optimise Director Remuneration

One of the most impactful things you can do is get the balance right between salary and dividends. Blend a salary up to the personal allowance (£12,570 tax-free) with dividends, which are taxed at lower rates post-allowance. Dividends also benefit from the £500 dividend allowance (currently frozen).

This split reduces both income tax and National Insurance contributions significantly compared to drawing everything as salary.

2. Claim Every Allowable Expense

Many directors miss out on legitimate deductions simply through lack of awareness. You can deduct:

• Home office costs — simplified rate of £6/week or actual cost method
• Business travel — including mileage at HMRC approved rates
• Professional subscriptions — memberships directly related to your trade
• Marketing and advertising — website, social media, PR costs
• Training and development — courses that improve skills relevant to your business

3. Maximise Pension Contributions

Company pension contributions are fully deductible — and crucially, they don't attract National Insurance. This makes them one of the most tax-efficient ways to extract value from your company while building long-term wealth.

Contributions reduce your corporation tax liability directly, and the money grows in a tax-efficient pension wrapper. There are annual limits, so speak to an adviser to make the most of this.

4. Invest in Qualifying Assets

The government's capital allowances regime rewards businesses that invest in assets. Key reliefs for 2026 include:

5. Review Your Group Structure

If you operate multiple companies, your structure can significantly affect your tax position. Key considerations include:

1. Associated company thresholds Managing the associated company rules carefully protects the lower 19% corporation tax rate. Each associated company divides the thresholds, potentially pushing more profit into the 25% main rate.
2. Holding company structures A holding company can facilitate tax-efficient dividend flow between group companies and may provide Substantial Shareholding Exemption on asset disposals.
3. Transfer pricing If you have international operations, ensure intercompany charges are at arm's length and properly documented to avoid HMRC challenges.

Stay Compliant While You Save

HMRC's compliance focus in 2026 includes disguised remuneration, off-payroll working (IR35), and Making Tax Digital. Ensure you:

• File corporation tax returns on time — penalties start immediately after the deadline
• Maintain proper records for all expense claims
• Review contractor arrangements against IR35 rules regularly
• Are registered and compliant with Making Tax Digital for VAT and, where applicable, Income Tax
