Running a limited company comes with many benefits, but it also brings responsibility when it comes to tax. For many business owners, understanding how much tax is due and how to reduce their tax liability legally can feel overwhelming. However, there are several legitimate, HMRC-approved ways to manage your tax efficiently, helping you keep more of what your business earns without taking unnecessary risks.
In this article, we explain the most effective and compliant ways limited company owners can reduce their tax bill, including utilising allowable expenses, capital allowances, making company pension contributions or paying yourself strategically with dividends.
Whether you are newly established or looking to improve your current set up, these strategies can help you plan with confidence and clarity.
Paying yourself using a tax-efficient mix of salary and dividends
One of the most effective ways limited company owners can manage their tax bill is through how they take money out of their business.
Rather than paying themselves a full salary, many limited company owners choose a combination of salary and dividends.
This approach can be more tax-efficient because:
- A lower salary, often set around the individual National Insurance threshold of £12,570, helps maintain entitlement to state benefits while claiming tax relief in the limited company.
- Dividends are not subject to National Insurance.
- Dividends currently benefit from an annual £500 tax-free allowance and are taxed at lower rates than salary.
How individuals are taxed
Any dividends above the £500 allowance are taxed based on your Income Tax band.
The following rates will come into effect from April 2026 and are +2% higher for basic and higher rate tax bands:
| Income Tax band | Tax rate on dividends (over the allowance) |
| Basic rate | 10.75% |
| Higher rate | 35.75% |
| Additional rate | 39.35% |
For example:
For a company director wishing to withdraw a salary of £46,000 from their business, the most tax‑efficient structure typically involves combining a modest salary with dividends.
A common approach is to take a £12,570 salary alongside £37,700 in dividends.
The salary is set at the level of the personal allowance, meaning it attracts no Income Tax, while still providing the company with a tax‑deductible expense that can generate a 19–25% Corporation Tax saving, depending on profitability.
The remaining £37,700 is then drawn as dividends, which are taxed more favourably than salary:
- £500 taxed at 0% (dividend allowance).
- £37,200 taxed at 10.75%, resulting in a personal tax bill of £3,999.
This means the director receives £46,091 with only £3,999 of personal tax to pay.
Dividends remain attractive because they are taxed at lower rates and are not subject to National Insurance. However, they can only be paid from sufficient distributable reserves and must be properly declared to remain compliant with HMRC rules.
When managed correctly, a blended approach of salary and dividends offers an efficient and fully compliant way for business owners to reduce their overall tax burden.
Utilise allowable business expenses
Allowable expenses are costs incurred wholly and exclusively for business purposes. These expenses can be deducted from your company’s income when calculating taxable profit, which helps reduce your overall Corporation Tax bill.
For example, if a company earns £120,000 and incurs £20,000 in allowable expenses, the company will only pay Corporation Tax on the remaining £100,000.
Allowable expenses for limited company’s typically include:
- Salaries and wages for directors and employees.
- Employer’s National Insurance contributions.
- Employer pension contributions.
- Office costs such as stationery, equipment, Wi-Fi and work mobile phones.
- Business mileage.
- Public transport costs for business travel (e.g. trains or buses).
- Subsistence costs, such as meals and accommodation during business trips or events.
If you work from home, you may be able to claim a proportion of your household bills based on the space used and time spent working.
For example:
- Annual running cost of home: £1,800.
- Rooms in the home: 6.
- Rooms used for work: 1.
- Days worked from home: 3 days per week.
Step 1: Work out the space used for work
1 room out of 6 = 1/6 of the home.
Step 2: Work out the time used for work
3 days out of 7 = 3/7 of the week.
Step 3: Calculate the claimable amount
£1,800 × 1/6 × 3/7 = £129.
Result:
You can claim £129 per year as a business expense.
The remaining £1,671 is personal use and not claimable.
The alternative is to claim a flat rate expense for using your home as an office which allows up to £6 per week or £312 per year.
Important note:
To remain compliant with HMRC rules, all expenses must be properly recorded, supported by evidence (e.g. receipts or invoices), and claimed accurately.
Keeping clear records ensures you claim everything you are entitled to without risking errors or penalties.
Use capital allowances for large purchases
Capital allowances allow limited companies to claim tax relief on certain large or long-term business assets, such as IT equipment, machinery, tools, office furniture, company vehicles and laptops. Instead of treating these purchases as everyday expenses, they are treated as capital investments and can be deducted from your profits over time.
The benefits of using capital allowances
When your company buys larger items, capital allowances can:
- Lower your Corporation Tax bill, by reducing your taxable profit.
- Improve cash flow as tax savings can be reinvested into the business.
- Support business growth by allowing you to upgrade equipment and technology without paying the full tax cost upfront.
If you own a smaller business
Most small businesses can use the Annual Investment Allowance (AIA), which currently allows up to £1 million of qualifying purchases to be deducted from profits in the year of purchase. This can significantly reduce your Corporation Tax bill for that year.
Contribute to company pensions
For limited company owners, employer pension contributions are one of the most tax-efficient ways to extract money out of the business while also building long-term investments.
When your company makes pension contributions on behalf of employees or directors, they are generally treated as an allowable business expense, meaning:
- They reduce the company’s taxable profit, lowering Corporation Tax.
- Unlike salary, pension contributions are not subject to Income Tax or National Insurance.
- They are paid before tax, meaning more money goes directly into the pension rather than being lost to tax.
This makes pension contributions particularly effective for business owners who want to reduce their tax liability while investing in their future.
To remain compliant, contributions must be made to a registered pension scheme, be wholly and exclusively for business purposes, and stay within annual pension allowance limits (may vary depending on circumstances).
A company can therefore contribute up to £60,000 per year (plus any carried forward unused amount) into director pension funds.
Offset trading losses (if applicable)
If your limited company makes a loss in a financial year, you may be able to use that loss to reduce tax in other financial periods. This is known as Loss Relief and can be a valuable saving tool, particularly for new businesses or those experiencing a temporary downturn.
Losses can typically be offset in the following ways:
- Carry forward losses.
Most commonly, trading losses are carried forward and offset against future profits of the same trade. This means your business can reduce its taxable profit in later years when it becomes profitable.
For example, if your company makes a £10,000 loss in year one, but £20,000 profit in year two, you can offset the loss from year one and only pay Corporation Tax on £10,000 profit.
- Carry back losses (under certain conditions).
You may be able to carry losses back to previous accounting periods to reclaim tax already paid, however this approach is limited and depends on the type of loss and timing.
- Group relief (if you own multiple companies).
If you own more than one company within a group, losses in one company can sometimes be offset against profits from another, which can reduce overall tax liability across the group.
Important note:
However, it is important to note that loss relief rules can be complex and are subject to specific HMRC criteria.
Due to this, it is essential that trading losses are correctly identified, calculated, and recorded in company accounts and that you use the correct method of relief for your circumstances.
At Cooper Associates Accountancy, our accountants can help you claim loss relief correctly and maximise the benefit; while ensuring you are complying with HMRC guidelines.
Strategic planning for income and expenses
The timing of when your business receives income and pays expenses can directly affect which accounting period they fall into and when tax is due. This approach can be a legitimate way to manage tax liability and cash flow, providing it remains commercially justified and compliant with HMRC guidelines.
Why timing matters
Corporation Tax is calculated based on your company’s accounting period. By carefully planning the timing of income and expenses, you can influence your taxable profit for that period, helping to reduce your tax liability or regulate cash flow.
Examples of tax planning
For example, you might choose to delay or bring forward new work and the right to income or selling assets for capital gains in a particular accounting period if it reduces the profit position of the company in a particular year.
Making decisions on the acquisition of new equipment can also utilise capital allowances in an earlier year if profits and tax are higher than expected. Likewise, making additional company pension contributions in a particular accounting period can mitigate tax.
This type of planning should always be done carefully with the help of an accountant to ensure you are complying with HMRC guidelines. However, when used appropriately, it can be an effective way to manage tax more efficiently.
