Buying a Phone Through Your Business in the UK: Save 20%+ on Tax in 2025/26
Buying a phone through your business in the UK is one of the simplest and most effective ways to reduce your tax bill. Whether you’re a limited company director upgrading your own handset or a sole trader equipping yourself for client work, purchasing through your business unlocks VAT reclaim, corporation tax deductions, and capital allowances that can cut the real cost of a flagship smartphone by a third or more.
However, the rules differ depending on your business structure, how you use the phone, and whether it’s purchased outright or acquired on contract. Understanding these distinctions is essential if you want to stay compliant with HMRC while maximising the financial benefits.

Whether you’re upgrading your own handset or equipping an entire team, Connection Technologies’ business mobile solutions can help you find the right deal at the best price.
How Much Can You Actually Save? Real-World Example for 2025/26
Before diving into the detailed rules, let’s look at a concrete example of what buying a phone through your business in the UK actually saves you. We’ll use a popular flagship device — the Samsung Galaxy S25 Ultra — on a 24-month business contract.
Scenario: A VAT-registered limited company purchases a Samsung Galaxy S25 Ultra on a 24-month business mobile contract.
- Upfront handset cost (inc. VAT): £1,440
- Monthly contract (inc. VAT): £45/month × 24 months = £1,080
- Total cost over 24 months (inc. VAT): £2,520
Step 1 — VAT Reclaim (20%):
- VAT on handset: £1,440 ÷ 6 = £240 reclaimed
- VAT on contract: £1,080 ÷ 6 = £180 reclaimed
- Total VAT reclaimed: £420
Step 2 — Corporation Tax Deduction at 25% (2025/26 rate):
- Net cost after VAT: £2,520 − £420 = £2,100
- Corporation tax saving: £2,100 × 25% = £525 saved
Total tax saving: £420 (VAT) + £525 (corporation tax) = £945
Effective cost to the business: £2,520 − £945 = £1,575
That’s a 37.5% saving compared to buying personally.
And that’s just for one phone. If you’re equipping a team of five, multiply those savings accordingly — potentially over £4,700 saved across a single contract cycle.
Tax Benefits of Buying a Phone Through Your Business in the UK
One of the primary reasons business owners purchase phones through their company is the potential for significant tax savings. Here are the main advantages for the 2025/26 tax year:
VAT Reclaim (Save 20% Immediately)
If your business is VAT-registered, you can reclaim the VAT on a mobile phone purchased for business use. This applies to both the handset cost and the monthly contract charges.
Use this simple formula to calculate your VAT saving on any business mobile purchase:
VAT reclaimable = Total cost (inc. VAT) ÷ 6
| Phone Cost (inc. VAT) | VAT You Reclaim | Real Cost to Business |
|---|---|---|
| £600 | £100 | £500 |
| £900 | £150 | £750 |
| £1,200 | £200 | £1,000 |
| £1,500 | £250 | £1,250 |
| £1,800 | £300 | £1,500 |
The same formula applies to your monthly contract charges. A £40/month (inc. VAT) tariff saves you £6.67/month — that’s £160 over a 24-month contract.
The same principle applies to ongoing tariff costs — every monthly bill becomes 20% cheaper in real terms when you reclaim the VAT.
Corporation Tax Deduction (25% Rate for 2025/26)
For limited companies, the cost of a business mobile phone is treated as a legitimate business expense. This means the full cost (excluding VAT, which you’ve already reclaimed) reduces your taxable profits.
The UK corporation tax rate for the 2025/26 tax year remains at 25% for companies with profits over £250,000, with a small profits rate of 19% for companies with profits under £50,000 (marginal relief applies between £50,000 and £250,000).
| Phone (ex. VAT) | CT Saving at 19% (profits under £50k) | CT Saving at 25% (profits over £250k) |
|---|---|---|
| £500 | £95 | £125 |
| £1,000 | £190 | £250 |
| £1,500 | £285 | £375 |
Capital Allowances (Claim 100% in Year One)
Mobile phones qualify for capital allowances under the Annual Investment Allowance (AIA). The AIA is permanently set at £1 million, meaning most businesses can deduct the full cost of the phone in the year of purchase, rather than depreciating it over several years. This provides an immediate tax benefit and simplifies your accounting.
Additionally, under the full expensing regime introduced in 2023 (now made permanent), companies investing in qualifying plant and machinery — including mobile phones — can claim 100% first-year capital allowances. This is particularly beneficial for larger fleet purchases.
Monthly Contract Costs Are Fully Deductible
Beyond the handset itself, your monthly airtime, data, and any additional services are fully deductible as business expenses. Over a typical 24-month contract, these savings add up considerably — especially if you’re running multiple lines for a team.
For example, a team of 10 employees on £35/month contracts generates £8,400 in deductible expenses over two years — reducing your corporation tax bill by up to £2,100 at the 25% rate.

Limited Company vs Sole Trader: Different Rules for Buying a Phone Through Your Business
The tax treatment of business phones varies significantly depending on whether you operate as a limited company or a sole trader. Here’s a detailed comparison:
Limited Company Phone Purchases
If you run a limited company, the business is a separate legal entity. This means:
- The company owns the phone — it’s a company asset, purchased with company funds and listed on the balance sheet.
- Full VAT recovery — provided the contract is in the company’s name, you can reclaim 100% of the VAT on both the handset and monthly charges.
- No Benefit in Kind (BIK) tax — HMRC allows one mobile phone per employee as a tax-free benefit, provided the contract is between the employer and the network provider. This is a significant advantage: the employee (including you as a director) pays no additional tax, and the company gets full relief. This exemption is found in ITEPA 2003, Section 319.
- Corporation tax deduction — the full cost reduces your company’s taxable profits at 25% (or 19% for small profits).
- Multiple phones — if you employ staff, you can provide each employee with one tax-free mobile phone under the same rules.
Sole Trader Phone Purchases
As a sole trader, there’s no legal separation between you and your business. This changes the picture:
- Mixed-use complications — HMRC expects you to only claim the business proportion of phone costs. If you use your phone 60% for business and 40% personally, you can only claim 60% of the costs.
- VAT recovery is partial — you can only reclaim VAT on the business-use percentage.
- No BIK exemption — the one-phone-per-employee exemption doesn’t apply because you’re not an employee of your own business.
- Income tax relief — you claim against income tax rather than corporation tax, at your marginal rate (20%, 40%, or 45% for the 2025/26 tax year).
- Simpler accounting — despite the limitations, claiming phone costs as a sole trader is straightforward. You simply include the business portion in your self-assessment expenses.
Quick Comparison Table
| Feature | Limited Company | Sole Trader |
|---|---|---|
| VAT reclaim | 100% (business contract) | Business-use % only |
| Tax deduction | Full cost against corporation tax (19–25%) | Business portion against income tax (20–45%) |
| BIK exemption | Yes (one phone per employee) | No |
| Personal use | Permitted under BIK rules | Must apportion costs |
| Contract name | Must be in company name | Can be personal or business name |
| Best for | Maximum tax efficiency | Simplicity with partial savings |

Business Phone Contract vs Personal Phone for Work
Many business owners wonder whether it’s worth getting a dedicated business phone contract or simply using their personal phone for work. Here are the key differences:
Advantages of a Business Phone Contract
- Full tax relief — business contracts qualify for complete VAT reclaim and tax deductions (for limited companies).
- Professional image — a separate business number keeps your personal and professional lives distinct.
- Better tariffs — business mobile deals often include more data, international minutes, and priority support.
- Easier accounting — no need to calculate business-use percentages when the entire contract is for business.
- Team management — business contracts allow centralised billing, shared data pools, and easier device management.
- Security features — many business plans include mobile device management (MDM), remote wipe capabilities, and enhanced security.
- 5G and priority network access — business plans from networks like EE and Vodafone increasingly offer prioritised 5G connectivity and guaranteed uptime SLAs.
Disadvantages of Using a Personal Phone
- Partial claims only — you can only claim the business-use portion of costs.
- HMRC scrutiny — mixed-use claims can attract questions during tax investigations.
- No BIK exemption — personal contracts don’t qualify for the tax-free phone benefit.
- Data security risks — personal devices may lack the security controls needed for business data, which is increasingly important under UK GDPR requirements.
- Work-life boundary issues — without a separate number, you’re always “on call.”
For most businesses, a dedicated business phone contract is the smarter choice — both financially and operationally.
How to Buy a Phone Through Your Limited Company (Step-by-Step)
If you’ve decided that buying a phone through your business is the right move for your limited company, follow these steps to ensure you maximise tax benefits and stay compliant:
Step 1: Choose the Right Phone and Plan
Compare business mobile deals to find a handset and tariff that suits your needs. Consider data allowances, international roaming, and whether you need features like Wi-Fi calling or 5G. Get a free quote from Connection Technologies to compare options from all major UK networks.
Step 2: Ensure the Contract Is in the Company Name
This is critical. For the BIK exemption to apply and for full VAT recovery, the contract must be between your limited company and the mobile network provider. A contract in your personal name won’t qualify, even if the company pays for it.
Step 3: Pay from the Company Bank Account
All payments — both the upfront handset cost and monthly charges — should come directly from your business bank account or company credit card. This creates a clear audit trail.
Step 4: Record It Correctly in Your Accounts
The handset should be recorded as a fixed asset (or expensed immediately under AIA). Monthly charges go under telecommunications or mobile phone expenses. Your accountant can advise on the best treatment for your specific situation.
Step 5: Keep Records for HMRC
Retain all invoices, contracts, and proof of payment. HMRC may request these during an enquiry, and good record-keeping makes everything straightforward. You must keep these records for at least six years from the end of the accounting period.
Step 6: Limit to One Phone Per Person
Remember, the BIK exemption covers one mobile phone per employee. If you provide a second phone to the same person, the additional device becomes a taxable benefit. However, replacing a phone (e.g., upgrading at the end of a contract) does not count as a second phone.

How Sole Traders Can Claim Phone Costs
While sole traders face more restrictions when buying a phone through their business, there are still legitimate ways to reduce your phone costs:
Proportional Use Method
The most common approach is to calculate the percentage of business use and claim that proportion of your total phone costs. For example:
- Monthly phone bill: £50
- Estimated business use: 70%
- Monthly claim: £35
- Annual claim: £420
- Tax saving at 20% basic rate: £84/year
- Tax saving at 40% higher rate: £168/year
Keep a log of your usage for at least a representative period (one to three months) to support your claimed percentage. This doesn’t need to be a call-by-call record — a reasonable estimate based on your working patterns is acceptable.
Simplified Expenses
HMRC’s simplified expenses scheme allows sole traders to use flat rates for certain costs, though mobile phones aren’t specifically covered by flat-rate allowances. You’ll generally need to use the actual-cost method with a business-use percentage.
Separate Business Phone (The Best Option)
The simplest approach for sole traders is to have a completely separate phone and contract for business use. If you’re buying a phone through your business exclusively for work purposes, you can claim 100% of the costs — no apportionment needed.
This also makes your accounting much simpler and reduces the risk of HMRC queries. It’s the approach we recommend to most sole traders we work with.
What You Can Claim
- Monthly contract or pay-as-you-go costs (business proportion)
- Handset purchase price (business proportion)
- Business-related apps and subscriptions
- Phone cases, screen protectors, and accessories used for work
- Repairs and insurance (business proportion)
Common HMRC Rules and Pitfalls to Avoid
When buying a phone through your business in the UK, there are several HMRC rules and common mistakes to be aware of:
The One Phone Per Employee Rule
The BIK exemption under ITEPA 2003, Section 319 only applies to one mobile phone per employee. If a company provides two phones to the same employee, the second phone is a taxable benefit in kind and must be reported on a P11D.
Contract Must Be in the Company Name
For limited companies, the contract must be between the company and the network provider — not in the employee’s personal name. If the contract is personal, the company can still reimburse the employee, but the BIK exemption won’t apply and VAT recovery becomes complicated.
Don’t Forget About SIM-Only Deals
The same tax rules apply to SIM-only deals. If your employees already have suitable handsets, a business SIM-only plan is still fully deductible and VAT-reclaimable. This can be a cost-effective option, especially for BYOD (bring your own device) policies.
Tablets and Smartwatches
Note that the BIK exemption specifically covers mobile phones. Tablets, smartwatches, and other devices don’t qualify for the same exemption — though they may still be deductible as business expenses if there’s a genuine business need. Speak to your accountant about the best treatment.
Record Keeping
HMRC expects you to retain records for at least six years. Keep all invoices, contracts, and bank statements showing payments. Digital records are perfectly acceptable — in fact, they’re preferred under Making Tax Digital requirements.
Buying Phones for Your Team: Scaling Up
If you’re not just buying a phone for yourself but equipping a whole team, the savings multiply quickly. Here’s what a fleet purchase looks like for a small business:
| Cost Element | Per Phone | 10 Phones (24 months) |
|---|---|---|
| Handset + contract (inc. VAT) | £1,800 | £18,000 |
| VAT reclaimed | −£300 | −£3,000 |
| Corporation tax saving (25%) | −£375 | −£3,750 |
| Total saving | £675 | £6,750 |
| Effective cost | £1,125 | £11,250 |
That’s £6,750 saved — plus every employee gets a tax-free phone with no P11D liability.

Frequently Asked Questions: Buying a Phone Through Your Business UK
Can I buy an iPhone through my limited company?
Yes, absolutely. You can buy any mobile phone — iPhone, Samsung, Google Pixel, or any other brand — through your limited company. The phone becomes a company asset, and you benefit from full VAT reclaim, corporation tax deductions, and the BIK exemption. Just ensure the contract is in the company name and paid for from the company bank account.
Is there a limit on how much I can spend on a business phone?
There’s no specific HMRC limit on the cost of a business mobile phone. However, the expense must be “wholly and exclusively” for business purposes (or qualify under the BIK exemption for limited companies). In practice, any mainstream smartphone — even a top-tier iPhone 16 Pro Max or Samsung Galaxy S25 Ultra — is considered a reasonable business purchase.
Can I buy a phone through my business if I’m not VAT-registered?
Yes, you can still buy a phone through your business and claim it as a business expense against corporation tax or income tax. You simply won’t be able to reclaim the VAT. For limited companies, the BIK exemption still applies regardless of VAT registration status.
What about buying refurbished phones through my business?
Refurbished phones receive the same tax treatment as new phones. They can be claimed as a business expense, and VAT can be reclaimed if you’re VAT-registered (provided the seller charges VAT). Refurbished devices can be an excellent way to equip a team cost-effectively.
Can my company buy me a phone and a tablet?
Your company can buy both, and both are deductible as business expenses. However, only the mobile phone qualifies for the BIK exemption. A tablet provided for personal use would be a taxable benefit in kind and must be reported on a P11D — unless it’s only used for business purposes.
What happens to the phone when I leave the company?
If an employee leaves and keeps the company phone, the market value of the phone at that point becomes a taxable benefit. The company should either reclaim the device or account for the transfer appropriately. Many businesses include phone return clauses in employment contracts.
Can I switch my existing personal contract to a business contract?
Most networks allow you to transfer a personal contract to a business account, though the process varies. It’s often easier to start a new business contract at your next upgrade. Contact our team and we can advise on the best approach for your situation.
Do these rules apply to phone accessories too?
Yes. Cases, screen protectors, chargers, car mounts, and other accessories purchased for business phones are deductible business expenses. VAT can be reclaimed on these items too if you’re VAT-registered.
