How an Accountant Can Save Your Limited Company Thousands
Running a limited company gives you flexibility — but flexibility is worthless if you don't know how to use it. Every year, directors leave thousands of pounds on the table simply because they don't know what's available to them: the right salary and dividend split, employer pension contributions, legitimate expenses, or the tax advantages of an electric company car. All figures and rates in this guide are correct as of 28 July 2026.
- The right salary/dividend split can save thousands in tax and National Insurance every year.
- Employer pension contributions are 100% corporation tax deductible and carry no NI charge — up to a £60,000 annual allowance.
- Expenses that are "wholly and exclusively" for business use reduce your taxable profit — but the rules trip up many directors.
- An electric company car currently attracts a benefit-in-kind rate of just 3% for 2026/27, a huge saving versus a petrol/diesel equivalent or extra salary.
- A proactive accountant does far more than file your accounts — they actively plan your tax position throughout the year.
1. Director Salary & Dividends: Getting the Split Right
One of the simplest — and most overlooked — ways an accountant saves a limited company money is structuring how the director is paid. Most owner-directors take a low salary combined with dividends, rather than one large salary, because the tax treatment is significantly more favourable.
For 2026/27, the personal allowance remains £12,570 — income up to this level is tax-free. A salary set at or around the National Insurance threshold means the company pays little to no employer NI, while still counting as a qualifying payment for state pension purposes. Dividends are then drawn from remaining profits, taxed separately from salary, with basic rate dividend tax currently at 8.75%.
Getting this wrong — taking a salary that's too high, or drawing dividends without checking there are sufficient retained profits — can trigger unnecessary tax bills or even illegal dividend issues. This is exactly the kind of detail covered under our Payroll Services, working alongside your Personal Taxation planning to make sure company and personal tax positions are optimised together.
2. Employer Pension Contributions: A Triple Tax Win
Employer pension contributions are one of the most tax-efficient ways to extract value from a limited company — yet they're consistently underused. Contributions made directly by the company into a director's pension are 100% deductible against corporation tax, and unlike salary, they attract no employer or employee National Insurance at all.
For 2026/27, the standard annual allowance is £60,000, meaning a company can contribute a substantial sum each year while reducing its taxable profits pound for pound. For directors who don't need to draw all their company profit as immediate income, this is often the single biggest saving an accountant can identify — building long-term wealth while cutting the current year's tax bill.
3. Expenses That Are Wholly and Exclusively for Business
HMRC allows a limited company to deduct expenses that are incurred "wholly and exclusively" for the purposes of the trade. Getting this right reduces your corporation tax bill; getting it wrong can trigger enquiries and penalties. Commonly claimable costs for limited company directors include:
- Home office costs (a reasonable proportion of utilities, or a simplified flat rate)
- Business travel and subsistence (excluding ordinary commuting)
- Professional subscriptions and trade body memberships
- Accountancy, legal and other professional fees
- Business insurance, including professional indemnity cover
- Mobile phone contracts used for business purposes
- Training and continuing professional development directly related to your trade
- Equipment, software and other tools of the trade
An experienced accountant will review your spending pattern and flag which costs qualify, which need apportioning between business and personal use, and which are simply not allowable — protecting you from an unwelcome surprise at year end. This is a core part of what's covered by our Limited Company Accounts service.
4. Electric Company Cars: A Major Tax-Saving Opportunity
Providing an electric vehicle through the company remains one of the most powerful tax planning tools available to limited company directors. For 2026/27, the benefit-in-kind (BIK) rate on fully electric cars is just 3% of the vehicle's list price — dramatically lower than the rate charged on petrol or diesel equivalents, which can run as high as 37%.
Beyond the low BIK charge, electric company cars also benefit from no fuel duty on business charging costs, no road tax under current rules, and the company can usually claim capital allowances on the purchase. Compared to taking additional salary or dividends to fund a personal car purchase, running an EV through the company can represent a substantial National Insurance and income tax saving for the director, alongside a corporation tax deduction for the business.
Every director's circumstances differ, so it's worth reviewing the sums for your specific vehicle and mileage pattern — our Company Car Tax Guide walks through the calculations in detail.
5. The Value of a Proactive Accountant
Beyond salary structuring, pensions, expenses and company cars, the biggest saving many directors make is simply having an accountant who plans ahead rather than just filing returns after the fact. A proactive accountant will:
- Run tax planning reviews well before your company's year end, not after
- Flag upcoming deadlines so you avoid late filing and late payment penalties
- Identify reliefs and allowances you may not know exist
- Keep you compliant as legislation and rates change year to year
- Give you a clear, jargon-free picture of your company's financial position
This is the difference between "compliance" accounting and genuine advisory support — and it's usually where the largest savings are found. If you'd like a review of your own company's position, you can book a call with our team or take a look at our pricing to see how we can help.

What's the ideal salary to take as a limited company director in 2026/27?
There's no single "correct" figure — it depends on your personal allowance usage, whether you want to maintain state pension qualifying years, and your company's profitability. Most directors take a modest salary up to a NI-efficient threshold and draw the rest as dividends, but this should always be reviewed with your accountant.
Can my company pay into my personal pension?
Yes — employer pension contributions can be paid directly from the company into your pension scheme. They're fully deductible against corporation tax and don't attract National Insurance, making them one of the most tax-efficient ways to extract value from the business.
What happens if I claim an expense that isn't "wholly and exclusively" for business?
If HMRC challenges an expense and it isn't wholly and exclusively for business purposes, it can be disallowed for corporation tax purposes and may also be treated as a taxable benefit in kind for you personally. Keeping clear records and checking with your accountant before claiming unusual costs avoids this.
Is an electric car really cheaper than taking the money as salary?
In most cases, yes. With a benefit-in-kind rate of just 3% for 2026/27, the personal tax cost of an EV is far lower than the income tax and National Insurance you'd pay on the equivalent salary needed to buy or lease a car privately — and the company can also benefit from capital allowances.
How often should my accountant review my company's tax position?
Ideally at least twice a year — once mid-year to allow time to act on any planning opportunities, and again shortly before your year end to finalise decisions like pension contributions, dividends and capital expenditure.
What's the current rate of corporation tax for limited companies?
The main rate of corporation tax is 25% for companies with profits above £250,000, with a small profits rate and marginal relief available for lower-profit companies. Your accountant can confirm exactly which rate applies to your business.
