Self-Employed Working from Home Expenses in the UK
Working from home as a self-employed individual in the UK comes with various expenses that can be claimed to reduce taxable income. Understanding what you can and cannot claim is essential for maximising deductions while staying compliant with HMRC regulations.
1. What Expenses Can You Claim?
Self-employed individuals can claim two types of expenses: direct expenses (fully claimable) and proportional expenses (partly claimable based on business use).
Fully Claimable Expenses
These are costs incurred solely for business purposes, including:
- Office supplies (paper, printer ink, pens, etc.)
- Business phone and internet bills (if separate from personal use)
- Software subscriptions and cloud storage for business use
- Advertising and marketing costs
- Professional fees (accountants, consultants, legal fees related to business)
Proportionally Claimable Expenses
These expenses must be shared between personal and business use and claimed proportionally:
- Rent or Mortgage Interest – Claim the portion of your home used for business.
- Utilities (Electricity, Water, Heating) – Deduct the percentage used for business activities.
- Council Tax & Home Insurance – If applicable, claim a business-use proportion.
- Home Maintenance & Repairs – If the repair is specifically for your home office space, you may be able to deduct the cost.
- Depreciation (Wear and Tear) – If applicable, claim a portion of the value of your home office equipment.
2. How to Calculate Home Office Expenses
There are two ways to claim home office expenses:
A. Actual Cost Method
Calculate the portion of your home used for business based on:
- Floor Space Percentage – If your home office is one room in a five-room house, you can claim 20% of relevant expenses.
- Usage Hours – If the room is used part-time for business, adjust the percentage accordingly.
B. Simplified Expenses (Flat Rate Method)
HMRC offers a simplified expense method based on the number of hours you work from home per month:
| Hours Worked from Home per Month | Flat-Rate Deduction |
|---|---|
| 25 to 50 hours | £10 per month |
| 51 to 100 hours | £18 per month |
| 101+ hours | £26 per month |
This method is easier but may not always provide the maximum deduction.
3. Record-Keeping and Compliance
To ensure compliance with HMRC, keep detailed records and receipts of all claimed expenses. Maintain:
- Utility bills, rent/mortgage statements, and insurance documents
- Invoices and receipts for business-related purchases
- Logs of business usage for shared expenses
4. Common Mistakes to Avoid
- Claiming personal expenses as business expenses.
- Failing to keep proper records of business use.
- Overestimating business-use percentage, which could trigger an HMRC audit.
5. Should You Use an Accountant?
While small business owners can handle their own tax returns, consulting an accountant can help optimise deductions and avoid errors.
Conclusion
Understanding self-employed home office expenses can significantly reduce your taxable income. Choosing the right method—actual cost or flat rate—depends on your specific situation. Keeping accurate records ensures compliance and maximises tax relief. If in doubt, seek professional advice to make the most of available deductions.
