Can You Claim Broadband as a Business Expense in 2026? UK Tax Guide Quick answer:
Yes. UK businesses can normally claim broadband costs where they are genuinely incurred for business purposes.
But the amount you can claim depends on how the broadband is used and how your business is structured.
Situation Typical treatment
Sole trader using home broadband for work and personal use
Claim the reasonable business proportion
Sole trader with a separate business-only connection
Potentially claim the full business cost
Limited company broadband at office premises
Normally a company business expense
Company provides home broadband solely for work
Can potentially be provided tax-free if HMRC conditions are met
Director already has personal home broadband
Company reimbursement needs more care; existing private cost is not automatically tax-free
The important rule is not simply whose name appears on the bill.
You need to consider:
why the connection was purchased
how much is used privately
whether the cost already existed before the business use
whether the business is a sole trader or limited company

This guide provides general information and is not personal tax advice. Tax treatment depends on individual circumstances. Consider checking the treatment with HMRC or a qualified accountant if you are unsure.
Key Takeaways
Sole traders can claim the business element of broadband costs.
Mixed home broadband normally needs a reasonable business/private split.
A separate business-only connection is easier to justify as a full business expense.
The self-employed working-from-home flat rate does not include broadband or telephone costs.
Broadband can therefore be claimed separately from simplified homeworking expenses.
Limited-company treatment depends on whether the company provides the connection or reimburses a personal cost.
Employer-provided home broadband can be tax-free where it is provided solely for work and private use is not significant.
From 6 April 2026, new reimbursement rules can apply where an employee incurs qualifying costs on behalf of the employer.
Keep invoices and a reasonable record of how you calculated any business-use proportion.
Do not assume that putting broadband through the company automatically makes all private use tax-free.
Can a Sole Trader Claim Broadband? Yes.
HMRC allows self-employed businesses to claim internet costs as an allowable business expense. so if the same broadband connection is also used personally, you can normally claim only the business share.
For example:
Annual broadband bill: £480
Reasonable estimated business use: 60%
Potential allowable broadband expense: £288
The calculation should be reasonable and reflect the actual circumstances of your business.
How Should You Split Business and Personal Broadband Use? HMRC does not prescribe one universal broadband percentage.
A reasonable calculation might consider:
how many days you work from home
how many hours broadband is used for business
how many other household members use the connection
whether business use includes large downloads, backups or video calls
whether the connection would exist anyway for private use
A blanket “I work from home 50% of the week, therefore I claim 50%” calculation is not automatically correct.
Your method should be reasonable enough that you could explain it if HMRC asked.
Worked Example: Sole Trader Using Home Broadband Suppose you pay:
£45/month for home broadband
Your annual cost is:
£45 × 12 = £540
You estimate that 40% of the overall household broadband use relates to your business.
Your broadband expense would therefore be:
£540 × 40% = £216
The £216 would reduce your taxable business profit.
Does Claiming £216 Mean You Get £216 Back? No.
An allowable expense reduces taxable profit. It is not normally a pound-for-pound tax refund.
For example, if:
your taxable business profit before broadband is £30,000
you claim £216 of allowable broadband costs
your taxable profit becomes:
£29,784
The actual tax saving depends on your wider tax position.
Can You Claim 100% of Broadband as a Sole Trader? Potentially! but only where the cost genuinely relates wholly to the business.
This is much easier to justify where you have:
a separate broadband connection for the business
a dedicated office connection
a second line installed specifically for business
If your whole household uses the same connection for streaming, gaming and personal browsing, claiming 100% would generally be much harder to justify.
What If You Use Simplified Expenses for Working From Home? This is an important point that is often misunderstood.
Self-employed people working from home can use HMRC’s simplified homeworking expenses based on monthly working hours.
Business hours worked at home per month Current flat rate
25-50 hours
£10/month
51-100 hours
£18/month
101+ hours
£26/month
However, that flat rate does not include telephone or internet costs.
You can still calculate and claim the business element of your broadband separately.
Example: Simplified Expenses + Broadband Imagine you work from home for 110 hours every month – you could potentially use:
simplified homeworking expense: £26/month
plus your separately calculated business share of broadband
You do not need to choose between the homeworking flat rate and claiming broadband altogether.
Can a Limited Company Claim Broadband? Yes, but the setup matters.
There are several common scenarios.
Broadband at the Company’s Office
If the limited company pays for broadband at its business premises, this is normally a straightforward business expense.
Company Provides Broadband at a Director’s or Employee’s Home
Home broadband can potentially be provided without creating a taxable benefit where:
the company’s purpose is to enable the employee to perform their work
the connection is genuinely required for those duties
any private use is not significant
This is more straightforward where the employer arranges the service specifically for business use.
Director Already Has Personal Broadband
This is different – if you already pay £40/month for home broadband regardless of whether you work through the company, the company simply paying that existing personal bill is not automatically a tax-free business expense.
The tax position depends on:
whether there is an identifiable additional cost
whether the expense is being incurred on behalf of the company
whether HMRC’s employment-expense exemption conditions are met
Important 2026 Change for Limited Companies and Employees From 6 April 2026 , HMRC introduced a new exemption under Section 316ZA ITEPA 2003.
This can apply where an employee or director incurs expenditure on:
accommodation
supplies
services
on behalf of their employer and the employer subsequently pays or reimburses the cost.
For home broadband, the conditions still matter.
HMRC requires, among other things, that:
the expense is incurred on the employer’s behalf
the employer intends it to be used for work
the sole purpose of providing it at home is to enable the employee to perform their duties
private use is not significant
This does not mean every director can automatically reimburse their existing family broadband bill tax-free.
Existing Broadband vs New Broadband Required for Work HMRC makes an important distinction here.
You already had broadband
If you were already paying for broadband before you started working from home, there may be no additional household cost simply because you now use it for work.
You need a new connection because of work
If broadband did not previously exist and it is installed because it is necessary for the work, the position can be more favourable, and this distinction is particularly important for employees and company directors.
Sole Trader vs Limited Company: Broadband Tax Treatment
Scenario Sole Trader Limited Company
Home connection used personally and for work
Claim reasonable business share
Company reimbursement needs employment-tax analysis
Separate business-only connection
Full business cost may be allowable
Usually much easier to justify as company-provided business service
Office broadband
Allowable business expense
Company expense
Existing personal broadband reimbursed
Not applicable in same way
Not automatically tax-free
New home connection required solely for duties
Business treatment depends on use
May fall within employer-provided/reimbursement exemptions
Can Employees Claim Broadband Tax Relief? Employees have different rules from self-employed people – you cannot generally claim tax relief for a normal broadband subscription that is also available for private use.
HMRC’s working-from-home guidance specifically excludes costs such as broadband where the service is used for both business and private purposes.
The position may differ where the employer provides or reimburses a connection that meets the relevant business-use conditions.
Is Business Broadband Better for Tax? Not simply because the contract says “business broadband”.
The tax treatment depends on the purpose and use of the expense.
However, a separate business connection can make record keeping easier because:
business use is clearer
personal usage can be separated
the invoice is easier to support
the connection may include business-specific services
Business broadband can also include features such as:
static IP
4G/5G backup
business support
enhanced fault response
Should You Upgrade to Business Broadband Just for the Tax Deduction? Usually no.
This is an important commercial point – suppose:
home broadband costs £30/month
business broadband costs £50/month
Paying another £20/month purely because it is “tax deductible” rarely makes financial sense.
An expense only saves a proportion of its cost in tax.
Choose business broadband because the service is better for your business, not simply because you can deduct the bill.
When Business Broadband May Still Be Worth Paying More For The higher cost may be justified if you need:
better support
static IP
automatic broadband backup
better upload speed
minimum speed guarantees
enhanced SLA
See our Business Broadband Comparison .
What Records Should You Keep? Keep:
broadband invoices
contract details
proof of payment
notes showing the business/private split
the reasoning behind your percentage
details of any separate business connection
You do not necessarily need minute-by-minute usage logs.
The important thing is that the method is reasonable, consistent and supportable.

Common Broadband Expense Mistakes Claiming the Whole Home Broadband Bill Automatically
Mixed private and business use normally needs to be separated for a sole trader.
Assuming a Limited Company Can Pay Any Personal Broadband Bill Tax-Free
Company payment does not automatically remove employment-benefit rules.
Forgetting That Simplified Homeworking Expenses Exclude Broadband
Broadband can still be calculated separately.
Treating an Expense as a Refund
The expense reduces taxable profit; you do not normally receive the full expense back.
Buying More Expensive Broadband Solely for Tax Reasons
The service still needs to represent good value.
Our View: How We Would Approach It For a sole trader working from home:
Use a sensible business-use percentage and keep a brief note explaining your calculation.
For a sole trader with a genuinely separate business connection:
The full business cost can be much easier to support.
For a limited-company director:
If you want the company to cover broadband at home, structure it properly rather than simply moving an existing personal household bill into the company accounts.
For an office-based company:
Business broadband at the premises is normally one of the simpler operating expenses
.
What to Check Before Claiming Broadband
Are you a sole trader, partnership or limited company?
Is the broadband used personally as well?
Who holds the contract?
Would the broadband cost exist even without the business?
Was a separate connection installed specifically for work?
What is a reasonable business-use percentage?
Are you using simplified homeworking expenses?
Have you retained invoices?
Can you explain your calculation if HMRC asks?
Does your accountant agree with the treatment?
Our Verdict: Can You Claim Broadband as a Business Expense? Yes, but “broadband is tax deductible” is only the beginning of the answer.
For self-employed people, the key issue is separating business and personal use.
For limited companies, the key issue is whether the broadband is genuinely being provided or reimbursed for employment purposes and whether private use is significant.
Our practical approach is:
mixed home broadband: claim only the defensible business partseparate business line: usually much clearerlimited company home broadband: check the employment-tax treatment before reimbursing an existing household contractoffice broadband: normally a straightforward company expense
And do not pay more for broadband purely to get a larger tax deduction.

Frequently Asked Questions Can I claim broadband as a self-employed business expense?
Yes. HMRC allows internet costs as business expenses, but mixed personal and business use normally needs to be apportioned.
Can I claim 100% of my broadband?
Potentially if the connection is genuinely business-only. If the same home broadband is used personally, a reasonable business proportion is normally more appropriate.
Can I claim broadband as well as simplified working-from-home expenses?
Yes. HMRC’s simplified homeworking flat rate does not include telephone or internet expenses, so broadband can be calculated separately.
Can my limited company pay for my home broadband?
Potentially, but the tax treatment depends on how the connection is provided, why it is needed and whether private use is significant.
What changed from 6 April 2026?
A new Section 316ZA exemption can apply in qualifying cases where an employee incurs expenditure on the employer’s behalf and the employer pays or reimburses it.
Can my company reimburse broadband I already had?
Do not assume this is automatically tax-free. Existing household broadband may not represent an additional business expense, and the relevant employment-tax conditions need to be considered.
Do employees get tax relief on home broadband?
Normally not where the broadband is also available for private use. Separate employer-provided or qualifying reimbursed services can have different treatment.
How should I calculate business broadband use?
Use a reasonable method based on your circumstances and keep a note showing how you reached the percentage.
Does claiming broadband mean HMRC pays the bill?
No. An allowable expense reduces taxable profit; the tax saving is only a proportion of the cost.
Should I buy business broadband for tax reasons?
Not on tax grounds alone. Choose it if the support, speed, static IP, backup or business service level makes the higher cost worthwhile.
