Starting and running a limited company is a popular choice for many UK business owners because it offers opportunities to operate efficiently and plan tax effectively. However, to save tax legally and reduce your overall tax burden, it’s important to understand how limited company tax works and what strategies are available in 2026. Keeping compliant with HMRC rules while using effective tax planning can improve cash flow and retain more profit.
Paying Yourself
One of the main ways directors of a limited company can reduce tax is through a tax-efficient mix of salary and dividends. A limited company pays corporation tax on profits first, and after tax profits can be distributed as dividends to shareholders. Dividends are not subject to National Insurance Contributions (NICs), which makes them more tax-efficient than salary alone.
A common strategy is to take a small salary up to your personal allowance and then take the remainder of income as dividends. Because dividends are taxed after corporation tax and attract no NICs, this approach often reduces the overall tax you pay. However, from April 2026 dividend tax rates will be higher than in prior years, with basic and higher rate dividend tax increasing by 2 percentage points.
Utilising Your Spouse or Partner’s Allowances
If your spouse or civil partner is a shareholder in your company and has unused tax allowances or lower income, allocating shares to them can spread dividend income more tax-efficiently. Always seek tailored advice to ensure this aligns with your wider family tax position and complies with relevant HMRC guidance.
Employer Pension Contributions
Making pension contributions on behalf of directors and employees can be an effective tax-saving strategy. Contributions made by the company to approved pension schemes reduce your corporation tax liability because they are an allowable business expense. Pension contributions also build future retirement income and avoid NICs on both employer and employee contributions.
Claiming Allowable Expenses
Your limited company can claim a wide range of allowable business expenses that reduce taxable profits. Typical expenses include office costs, travel expenses, software subscriptions, professional fees, training costs, and other costs incurred wholly and exclusively for business purposes. Accurate records and valid supporting receipts are essential when claiming expenses.
Timing Dividend Declarations
Another legitimate planning technique is timing dividend declarations across tax years to remain within your personal tax-efficient thresholds. Delaying or advancing dividends can help you use allowances effectively and avoid moving into a higher personal tax band. Consult a specialist accountant to decide the best timing based on your company’s profit profile and personal tax position.
VAT Planning
If your company is VAT-registered, choosing the appropriate VAT accounting scheme can improve cash flow. For example, the Cash Accounting Scheme for VAT allows you to pay VAT on sales only when you’ve been paid by your customers. This can ease cash pressures in businesses with slow-paying clients.
Dividend vs National Insurance
Because dividends do not attract National Insurance, using them alongside salary can reduce overall tax costs for directors. NICs are payable on salaries but not on dividends, making the right mix a key consideration for tax efficiency.
Stay on Top of Tax and Statutory Deadlines
Maintaining compliance with HMRC and Companies House deadlines is crucial to avoid penalties. Ensure your company files annual accounts, corporation tax returns, VAT returns and self-assessment on time. Timely filings also support better tax planning and reduce the risk of interest or late penalties.
FAQs on How to Save Tax on a Limited Company
How can a limited company save tax?
A limited company can save tax through tax-efficient profit extraction, claiming all allowable expenses, using pension contributions and structuring remuneration in a way that leverages allowances and reliefs.
What are allowable expenses for a limited company?
Allowable expenses are costs incurred wholly and exclusively for running your business. These may include office rent, professional fees, travel expenses and software subscriptions. Keeping accurate records is essential to support these claims.
How can pension contributions help reduce tax?
Company pension contributions reduce your corporation tax bill because they are deductible business expenses. They also build retirement savings without NICs on contributions.
What are the tax implications of paying dividends?
Dividends are paid from after-tax profits and attract income tax at dividend rates. From April 2026, dividend tax rates are higher than in previous years, so planning the level and timing of dividends matters for personal tax efficiency.
Can a limited company benefit from research and development tax credits?
Yes. Limited companies undertaking qualifying innovation or development activities may be eligible for R&D tax credits, which can reduce corporation tax or provide a payable tax credit. Aim to consult a specialist early to assess eligibility.
How can a limited company stay compliant while maximising tax savings?
Staying compliant requires keeping accurate financial records, filing returns on time, and seeking professional tax advice for any planning strategies. Using cloud accounting software and working with a specialist accountant can help you implement tax-efficient strategies while remaining compliant.
