Understanding Business Use of Phone and Internet
For online coaches, phone and internet aren't just utilities—they're the lifeblood of your business. Whether you're conducting client calls, delivering virtual sessions, marketing your services, or managing administrative tasks, these tools generate legitimate business expenses that can significantly reduce your tax liability. The fundamental question of what can online coaches claim for phone and internet comes down to accurately identifying the business portion of these mixed-use expenses. HMRC recognises that many self-employed individuals use these services for both personal and business purposes, and they provide clear guidelines for making proportional claims.
The key to maximising your claims lies in maintaining accurate records and using a reasonable method to apportion costs. Many coaches miss out on hundreds of pounds in tax relief each year simply because they're unsure about the rules or find the record-keeping overwhelming. This is where modern tax planning tools can transform your approach to expense tracking and ensure you claim everything you're entitled to while remaining fully compliant with HMRC requirements.
HMRC-Approved Methods for Claiming Expenses
When determining what can online coaches claim for phone and internet, HMRC accepts several approaches depending on your circumstances and the quality of your records. The simplest method involves claiming a flat rate if you work from home, but for phone and internet specifically, more detailed apportionment usually yields better results.
For broadband and landline costs, you can claim the business percentage based on actual usage. This requires tracking the time spent on business versus personal activities. Many coaches find that business use constitutes 60-80% of their total internet usage when accounting for client work, marketing, research, and administrative tasks. For example, if your monthly broadband costs £40 and you determine 70% is for business, you can claim £28 per month (£336 annually) as a business expense.
Mobile phone expenses follow similar principles. If you have a separate business phone with a dedicated contract, you can claim 100% of the costs. However, most coaches use a single device for both purposes. In this case, you'll need to apportion costs based on usage. Modern tax planning platforms like TaxPlan's expense tracking features can simplify this process by helping you categorise calls, data usage, and other mobile expenses throughout the year.
Calculating Your Legitimate Claims
Let's examine specific calculations to demonstrate what can online coaches claim for phone and internet in practical terms. For the 2024/25 tax year, these expenses reduce your taxable profits, providing relief at your marginal tax rate—20% for basic rate taxpayers, 40% for higher rate, and 45% for additional rate taxpayers.
Consider a typical scenario: an online coach paying £35 monthly for broadband and £25 monthly for a mobile contract. Through usage tracking, they determine 65% of broadband and 60% of mobile usage is business-related. Their annual claim would be:
- Broadband: £35 × 12 months × 65% = £273
- Mobile: £25 × 12 months × 60% = £180
- Total annual claim: £453
For a basic rate taxpayer, this claim reduces their tax bill by £90.60 (£453 × 20%). For a higher rate taxpayer, the saving increases to £181.20. These savings compound year after year, making accurate expense tracking well worth the effort.
Using dedicated tax calculation software ensures you never miss these deductions. The platform can automatically apply the appropriate tax rates and help you model different scenarios to optimise your tax position throughout the year rather than waiting until tax return season.
Record-Keeping Requirements and Best Practices
Understanding what can online coaches claim for phone and internet is only half the battle—proving it to HMRC is equally important. You must maintain records for at least 5 years after the 31 January submission deadline of the relevant tax year. For phone and internet expenses, this includes:
- Itemised bills showing call details and data usage
- Records of business versus personal usage percentages
- Documentation supporting your apportionment method
- Receipts for equipment purchases like routers or phones
Many coaches struggle with this administrative burden, which is where technology provides significant advantages. A comprehensive tax planning platform can store digital copies of bills, track usage patterns, and generate reports that demonstrate your methodology if HMRC ever questions your claims.
For those using simplified expenses, be aware that the flat rate method for working from home doesn't specifically cover phone and internet costs. You'll still need to claim these separately using one of the apportionment methods discussed above. The current flat rates for working from home are £6 per week (2024/25) without the need to justify specific costs, but this doesn't replace claiming phone and internet expenses directly.
Maximising Claims with Technology
The question of what can online coaches claim for phone and internet becomes much easier to answer with the right tools. Modern tax planning software transforms what was once a tedious manual process into an automated, accurate system that ensures compliance while maximising your claims.
Platforms like TaxPlan offer features specifically designed for self-employed professionals and business owners. These include expense categorisation, receipt scanning, usage tracking, and real-time tax calculations that show exactly how each claim affects your tax position. This proactive approach to tax planning means you can make informed decisions throughout the year rather than discovering missed opportunities after filing your return.
Beyond just phone and internet, a comprehensive tax planning solution helps you identify all allowable expenses specific to online coaching—from home office equipment and software subscriptions to professional development and marketing costs. This holistic approach ensures you're optimising every aspect of your tax position, not just the obvious expenses.
Common Pitfalls and How to Avoid Them
Many coaches unintentionally limit their claims or make errors when determining what can online coaches claim for phone and internet. The most common mistake is claiming 100% of costs without adequate justification, which can trigger HMRC inquiries. Conversely, being overly conservative means leaving legitimate tax savings on the table.
Another frequent error is failing to claim the business portion of phone handset costs. If you purchase a smartphone primarily for business use, you can claim the business percentage of the cost through capital allowances or the annual investment allowance. Similarly, claims for internet installation fees, router purchases, and other setup costs are often overlooked.
The solution lies in systematic tracking and documentation. Establishing a consistent method for recording business usage at the time it occurs—rather than estimating retrospectively—provides the most defensible position. Technology supports this process through mobile apps that allow instant categorisation of expenses as they occur, creating an audit trail that stands up to scrutiny.
When you understand exactly what can online coaches claim for phone and internet and implement robust systems to support your claims, you transform tax compliance from a source of stress into a strategic advantage. The savings generated through legitimate expense claims can be reinvested in growing your coaching business, developing new offerings, or enhancing your marketing efforts.
