Running a limited company comes with plenty of responsibilities. But one thing we see time and time again is directors paying more corporation tax than they need to, simply because they don’t realise what they can legitimately claim.
And most of the missed opportunities are not complicated tax schemes. They’re practical, everyday business expenses and director benefits that often get overlooked.
This guide is designed to be a practical checklist to help you understand some of the most common tax-saving opportunities available to limited company directors, and the rules you need to be aware of to use them properly.
Because good tax planning is not about avoiding tax. It’s about making sure you are not paying more than necessary while still investing back into yourself, your wellbeing, and your business.
First Things First: What Actually Reduces Corporation Tax?
Your limited company pays corporation tax on its taxable profits.
In simple terms, allowable business expenses reduce your company’s profit before tax is calculated. The actual tax saving depends on your company’s marginal rate of corporation tax.
For example:
- If your company incurs a £1,000 allowable expense, this does not mean your tax bill reduces by £1,000.
- Instead, it reduces your taxable profit by £1,000.
- The tax saving is therefore the corporation tax rate applied to that £1,000.
So if your company pays corporation tax at 25%, a £1,000 allowable expense could save £250 in corporation tax.
Simple in principle. But where things get interesting is understanding:
- What HMRC considers allowable
- Which benefits create additional personal tax
- Which benefits are most tax-efficient
- And how to structure things properly
Let’s dive into the opportunities directors commonly miss.
1. Business Mileage
One of the most commonly forgotten claims.
If you use your personal vehicle for business journeys, your company can reimburse you using HMRC’s approved mileage rates.
Current rates include:
- 55p per mile for the first 10,000 miles
- 25p thereafter
This covers:
- Fuel
- Wear and tear
- Insurance contribution
- Servicing
For a full breakdown of the latest mileage rates, you can read our guide here:
HMRC Mileage Rates 2026/27 Guide
What counts as business travel?
Typically:
- Visiting clients
- Travelling to networking events
- Temporary workplaces
- Supplier meetings
- Travel to qualifying training courses related to your business
But ordinary commuting to a permanent workplace usually does not qualify.
Practical tip
Keep a simple mileage log:
- Date
- Journey
- Purpose
- Miles travelled
Apps make this easy now, and good records are essential if HMRC ever asks questions.
2. General Business Travel
Directors often forget how broad legitimate travel expenses can be.
Allowable costs can include:
- Trains
- Flights
- Hotels
- Parking
- Taxis
- Congestion charges
- Subsistence (meals while travelling)
The key test is whether the travel was wholly and exclusively for business purposes.
Commonly missed examples
- Hotel stays for conferences
- Overnight accommodation before early meetings
- Networking event travel
- Co-working space visits
- Business retreats and strategy days
- Travel to qualifying business training
And yes, if there’s a genuine business purpose, overseas travel can absolutely qualify too.
3. Pension Contributions (One of the Biggest Wins)
Company pension contributions are one of the most tax-efficient ways to extract money from your business.
Why?
Because:
- The company usually receives corporation tax relief at its marginal tax rate
- There’s no employer National Insurance
- You personally don’t pay income tax on the contribution
It’s often dramatically more efficient than taking additional salary or dividends.
Example
If your company contributes £20,000 into your pension:
- The company will receive corporation tax relief based on its marginal tax rate
- You avoid personal tax on extraction
- Your future self benefits too
Important considerations
- Contributions must be wholly and exclusively for business purposes
- Pension annual allowance rules apply
- Large contributions should be planned carefully
For a deeper breakdown, read our guide here:
Making Pension Contributions via Your Limited Company
For many directors, pensions remain massively underused.
4. Relevant Life Insurance
This is one of the most overlooked director benefits.
A Relevant Life Policy is a tax-efficient life insurance policy paid for by the company.
Typically:
- The company pays the premiums
- The premiums are often corporation tax deductible
- The benefit is usually tax-free to beneficiaries
- No benefit-in-kind charge in many cases
For directors wanting life cover personally, this can be far more efficient than paying from post-tax income, but its important that the policy is set up correctly so advice is needed here.
5. Income Protection & Key Person Insurance
These are often confused, but both can be valuable.
Key Person Insurance
Protects the business if a key individual becomes seriously ill or dies.
Useful where:
- Revenue heavily depends on one person
- Specialist expertise is difficult to replace
- The business would suffer financially from absence
Tax treatment depends on policy structure and purpose.
Executive Income Protection
Some policies allow companies to provide income protection for directors and employees in a tax-efficient way.
This area gets nuanced quickly, so advice matters here.
But many directors do not even realise these options exist.
6. Trivial Benefits
A surprisingly useful exemption.
Your company can provide directors and employees with small benefits without tax implications, provided they:
- Cost £50 or less per benefit
- Are not cash or cash vouchers
- Are not performance-related
- Are not part of contractual remuneration
For directors of close companies
Directors of close companies are usually limited to:
- 6 trivial benefits per tax year
- Maximum annual value of £300
For employees
There is generally no annual limit for employees who are not directors of close companies, making this a great way to reward staff tax-efficiently.
Common examples
- Birthday gifts
- Christmas hampers
- Restaurant vouchers
- Bottles of wine
- Flowers
The key is ensuring the benefit remains genuinely “trivial” and not a disguised form of salary or bonus. For more information on this refer to our guide.
7. Staff Annual Party / Christmas Party
Yes, your company can pay for your Christmas party.
HMRC allows up to:
- £150 per head per year
And this can include:
- Food
- Drinks
- Entertainment
- Accommodation
- Transport
Importantly:
- It’s an exemption, not an allowance
- Go over £150 and the whole amount may become taxable
The event must also be mainly for employees.
For example:
- A company with one director and several subcontractors or clients attending may struggle to qualify
- In that scenario, HMRC may view this as business entertaining instead, which is generally not tax deductible
We covered this in more detail here:
Christmas Tax Savings You Don’t Want to Miss
8. Private Medical Insurance
This one is less about corporation tax saving alone and more about overall value.
Your company can pay for private medical cover.
Usually:
- The company receives corporation tax relief
- The director pays benefit-in-kind tax personally
- The company also pays employer’s National Insurance on the value of the benefit
So why do directors still do it?
Because:
- Access to healthcare is faster
- It supports wellbeing
- It reduces disruption to the business
- The overall cost can still be worthwhile
For many business owners, protecting health is one of the smartest investments they make.
9. Electric Cars Through the Company
This has become hugely popular and for good reason.
Electric vehicles currently attract very low benefit-in-kind rates compared to petrol or diesel vehicles.
Potential advantages include:
- Corporation tax relief
- Capital allowances
- Low personal tax
- Reduced National Insurance
- Charging cost savings
In the right circumstances, electric vehicles can be incredibly tax-efficient.
But watch out for:
- Leasing vs purchasing differences
- Personal usage implications
- Charging equipment rules
- Salary sacrifice interactions
This is an area where tailored advice matters.
10. Mobile Phones
A company can usually provide:
- One mobile phone per employee/director
- Including contracts and line rental
- Without creating a taxable benefit
However, the contract must be in the name of the company.
If the mobile contract remains in your personal name and the company simply reimburses you, the exemption may not apply in the same way.
11. Use of Home as Office
If you work from home, your company may be able to contribute toward household costs.
Options include:
- Simplified flat-rate claims
- Formal rental agreements
- Reimbursement of incremental costs
Potential claim areas:
- Electricity
- Heating
- Broadband contribution
- Office space usage
For many directors, “simple and sensible” usually means using HMRC’s flat-rate allowance of £6 per week without needing detailed calculations.
More complicated arrangements can sometimes create:
- Capital gains tax issues
- Administrative burdens
- HMRC scrutiny
Usually, keeping things proportionate is the best approach.
12. Professional Development & Training
Training is often deductible where it:
- Maintains or updates existing skills
- Relates to your current business activities
Examples:
- Industry courses
- Conferences
- CPD memberships
- Technical training
- Business coaching
What’s usually not allowable?
Training for an entirely new trade or profession.
13. Professional Subscriptions & Memberships
Many directors forget these completely.
Allowable examples may include:
- Trade associations
- Industry memberships
- Professional subscriptions approved by HMRC
Examples:
- Chartered Institute of Marketing (CIM)
- CIPD
- Federation of Small Businesses (FSB)
- British Chambers of Commerce
- Creative industry memberships
The membership should relate to your business or profession.
14. Staff Welfare & Wellbeing
This is an area many business owners either overlook entirely or misunderstand.
Some wellbeing expenses can qualify as allowable business costs, while others may create taxable benefits.
Potentially allowable areas include:
- Eye tests for employees using display screen equipment
- Employer-provided counselling services
- Annual health checks
- Flu vaccinations
- Employee Assistance Programmes (EAPs)
- Certain workplace wellbeing initiatives
Important rules to understand
Eye tests
If employees regularly use screens as part of their role, the company can generally pay for eye tests without creating a taxable benefit.
However, paying for regular prescription glasses usually creates a taxable benefit unless they are specifically required solely for screen use.
Health screenings & medical checks
One annual health screening and one medical check-up per employee per year can often qualify for exemption.
Counselling services
Certain welfare counselling services can be exempt provided they relate to:
- Stress
- Mental health
- Financial wellbeing
- Workplace issues
But the exemption does not normally extend to:
- Medical treatment
- Leisure activities
- General wellbeing perks unrelated to work
Gym memberships
A common misconception.
In most cases:
- Company-paid gym memberships are taxable benefits
- The employee/director usually pays personal tax on the value
- The company may also pay employer’s National Insurance
The key takeaway?
Just because something supports wellbeing does not automatically make it tax-free.
15. Equipment & Technology
This sounds obvious, but many directors still personally pay for business equipment unnecessarily.
Potential claims include:
- Laptops
- Monitors
- Office furniture
- Software subscriptions
- Cameras
- Printers
- Headsets
- Business tools
If the business uses it, the business should usually pay for it directly.
16. Annual Investment Allowance (AIA)
If your business purchases qualifying equipment or assets, you may be able to claim full tax relief through the Annual Investment Allowance.
This can apply to:
- Machinery
- Equipment
- Tools
- Office fit-outs
- Certain commercial vehicles
Timing large purchases properly around year-end can make a significant difference to corporation tax.
17. Charitable Donations
Company charitable donations can:
- Reduce corporation tax
- Support causes aligned with your business values
- Strengthen brand reputation
However:
- The donation must usually be made to a UK registered charity
- Payments must be genuine donations
- Sponsorship works differently from charitable giving for tax purposes
18. Director Salary Planning
A surprisingly common issue:
Directors either take too much salary… or not enough.
Getting the balance right between:
- Salary
- Dividends
- Pension contributions
- Benefits
…can significantly affect:
- Corporation tax
- National Insurance
- Personal tax efficiency
If you are a client of Orenda Collective, salary levels are something we proactively review for you throughout the year to ensure your remuneration remains as tax-efficient as possible.
19. Family Members Working in the Business
If family members genuinely work in the business, paying them a commercial salary may:
- Reduce overall family tax burden
- Reduce corporation tax
- Utilise unused personal allowances
But:
- The work must be real
- The pay must be reasonable
- Documentation matters
HMRC does look closely at this area.
20. Don’t Forget Timing
One of the simplest tax planning tools:
Timing your expenditure properly.
For example:
- Bringing forward equipment purchases
- Paying pension contributions before year-end
- Clearing reimbursable expenses promptly
- Reviewing benefits before the accounting period closes
Small timing decisions can create meaningful savings.
The Biggest Mistake Directors Make
The biggest issue is rarely missing one giant tax strategy.
It’s missing 15 small ones consistently over several years.
We regularly see business owners:
- Paying personal costs the company could cover
- Forgetting legitimate claims
- Missing tax-efficient benefits
- Or only getting support reactively rather than proactively
That’s exactly why we built our support packages to give business owners flexibility around the level of proactive support they need, from compliance-only support through to more strategic business and tax planning.
You can explore our service packages here:

Final Thoughts
Tax efficiency is not about chasing loopholes or complicated schemes.
It’s about:
- Understanding your options
- Using legitimate reliefs properly
- Structuring things intentionally
- And making your money work harder for both your business and your life
Because ultimately, every pound unnecessarily lost to tax is a pound that could have gone toward:
- Growth
- Financial security
- Your wellbeing
- Or simply making business feel less stressful
And that’s exactly the kind of straight-talking business support we care about at Orenda Collective.
