Understanding allowable expenses for contractors
For operations contractors working through their own limited companies, understanding what you can claim for phone and internet expenses is crucial for tax efficiency. Many contractors overlook legitimate business expenses, particularly around communication costs, leaving significant tax savings unclaimed. The key lies in understanding HMRC's specific rules around mixed-use assets and ensuring your claims are properly documented and proportionate to business use.
When considering what can operations contractors claim for phone and internet, it's important to recognize that these aren't just minor expenses. For contractors who rely heavily on mobile communication and internet connectivity for client work, research, and administrative tasks, these costs can represent substantial business expenditures. Properly claiming these expenses can reduce your corporation tax bill and improve your overall tax position.
Using dedicated tax planning software can transform how you approach expense claims. Rather than guessing at percentages or missing eligible claims, technology provides a structured approach to tracking, calculating, and documenting your business expenses throughout the tax year.
Mobile phone expenses: Contract vs personal use
HMRC allows contractors to claim the business portion of mobile phone costs, but the rules differ depending on how the contract is structured. If your company pays for the contract directly, you can claim 100% of the cost as a business expense, provided the contract is in the company's name. This is often the most straightforward approach when considering what can operations contractors claim for phone and internet.
For personally-owned phones used for business, you can claim a reasonable proportion of the costs based on actual business usage. Many contractors use the 70/30 split (70% business, 30% personal) as a starting point, but this should reflect your actual usage patterns. Keeping detailed records of business vs personal calls, or using app-based tracking, provides the evidence needed to support your claim.
The 2024/25 tax year maintains the same approach to mobile expense claims, with no specific monetary caps provided the claim represents genuine business use. For contractors using their mobile extensively for client communications, project management apps, and business research, these claims can easily reach £40-£60 monthly, representing significant annual tax savings.
Broadband and internet connectivity costs
When examining what can operations contractors claim for phone and internet, broadband expenses require careful consideration. Unlike mobile phones, broadband is typically considered a household utility with mixed personal and business use. HMRC allows claims for the business proportion of your broadband costs, calculated based on the time spent using the internet for business purposes.
A common approach is to calculate the percentage of business use relative to total household use. For example, if you work 40 hours weekly and your household has 112 waking hours (16 hours daily), your business use would be approximately 36%. On a £40 monthly broadband bill, this translates to £14.40 monthly claimable expense. More sophisticated calculations can factor in data usage patterns and specific business applications.

Home office and connectivity setup costs
Beyond ongoing monthly costs, contractors can also claim for equipment and setup expenses related to phone and internet usage. This includes routers, modems, ethernet cables, and other connectivity equipment necessary for your business operations. When purchased by your limited company, these represent capital allowances claims that can be offset against corporation tax.
For contractors working from home, you may also claim a proportion of household costs through simplified expenses or actual cost method. While this covers utilities like heating and lighting, it's separate from your specific phone and internet claims. Understanding the interaction between these different expense categories is essential when determining what can operations contractors claim for phone and internet.
The current corporation tax rate of 25% for profits over £250,000 (19% for profits up to £50,000, with marginal relief between £50,001-£250,000) means every £100 of legitimate expense claims saves £19-£25 in corporation tax. For contractors with significant communication costs, this represents meaningful tax optimization.
Documentation and compliance requirements
When claiming phone and internet expenses, documentation is paramount. HMRC expects contractors to maintain records that demonstrate the business purpose of expenses and the methodology used for apportioning mixed-use costs. This includes itemised phone bills highlighting business calls, records of business-related data usage, and calculations supporting your broadband apportionment.
Many contractors struggle with the administrative burden of tracking these expenses manually. This is where technology becomes invaluable – automated expense tracking through tax planning software ensures you capture all eligible claims while maintaining the audit trail HMRC requires. The software can automatically calculate appropriate percentages based on your working patterns and generate reports for your company records.
For contractors concerned about compliance, the simplified approach of having your company contract directly for business phones and claiming a reasonable percentage for broadband use typically satisfies HMRC requirements. The key is consistency and being able to demonstrate that your claims represent genuine business expenditure.
Strategic planning for maximum benefit
Understanding what can operations contractors claim for phone and internet is just the first step. Strategic planning throughout the tax year ensures you maximize your legitimate claims while minimizing administrative hassle. Consider conducting a communication audit every quarter to review your usage patterns and adjust your claim percentages accordingly.
Many contractors find that restructuring their communication arrangements – such as moving business mobile contracts into the company name and maintaining separate personal contracts – simplifies their expense claims and reduces compliance risk. This approach clearly delineates business and personal use, making it easier to demonstrate the business purpose to HMRC.
For contractors seeking to optimize their tax position, understanding what can operations contractors claim for phone and internet represents a significant opportunity. With proper planning and documentation, these everyday business expenses can translate into substantial tax savings while remaining fully compliant with HMRC requirements.
