What is Home Office Tax Relief?
Home office tax relief allows UK taxpayers to claim a portion of their household expenses as a business expense if they work from home regularly. This reduces your taxable income, ultimately leading to lower income tax and potentially National Insurance contributions. For the 2026 tax year, the rules remain largely consistent with recent years, but it’s crucial to stay updated as HMRC guidance can evolve. The relief aims to recognise the costs associated with using a portion of your home as your workplace – be it a dedicated office or even a corner of your living room. It’s an often overlooked benefit, so understanding your eligibility and how to claim it can significantly impact your finances.
Who is Eligible for Home Office Tax Relief in 2026?
Eligibility for home office tax relief depends on your employment status:
- Employees: You must work from home regularly and exclusively. ‘Regularly’ isn’t precisely defined by HMRC, but generally means more than just occasionally. Critically, you must be required to work from home by your employer. If you *choose* to work from home, you are less likely to qualify.
- Self-Employed Individuals: If you run your own business and use a part of your home for work, you’re generally eligible. This includes sole traders, partners in a partnership, and members of a limited liability partnership.
- Directors: Directors of limited companies can also claim, subject to the same rules as self-employed individuals, provided the work is genuinely for the benefit of the company.
When Relief Isn’t Available: You cannot claim relief if your home working is simply a matter of convenience. If your employer allows it but doesn’t require it, your claim may be rejected. Furthermore, you can’t claim for the portion of your home that is used for personal use only. Relief is strictly for the ‘business’ portion.
Allowable Expenses: What Can You Claim?
A wide range of household expenses can be claimed, proportionally to the amount of your home used for work. These include:
- Heating: A proportion of your heating bill.
- Electricity: A proportion of your electricity bill.
- Council Tax: A proportion of your Council Tax bill.
- Mortgage Interest (or Rent): A proportion of your mortgage interest payments or rent.
- Internet: A proportion of your internet bill.
- Phone Bills: A proportion of your phone bill (business calls only).
- Stationery: Costs of pens, paper, and other stationery.
- Office Furniture: Costs of items like desks, chairs, and computers (see section on ‘Home Office Setup & Tax Relief’).
Proportioning Costs: Accurate proportioning is key. HMRC typically accepts using the number of rooms in your home. For example, if your home has five rooms and you use one exclusively for work, you can claim 20% of eligible household bills. Time spent working from home can also be used as a basis for calculation, but this requires more detailed record-keeping.
Calculating Your Home Office Relief: Two Methods
You have two main options for calculating your home office relief: the Simplified Expenses method and claiming Actual Costs.
Comparison Table: Simplified Expenses vs. Actual Costs
| Feature | Simplified Expenses | Actual Costs |
|---|---|---|
| Complexity | Simple, minimal record-keeping | Complex, detailed record-keeping |
| Calculation | Flat rate per week/month | Proportion of actual household bills |
| Potential Relief | Lower, fixed amount | Potentially higher, depending on expenses |
| Suitable For | Low expenses, minimal home office setup | High expenses, significant home office usage |
Simplified Expenses: A Quick and Easy Approach
For the 2026 tax year, the flat rates for the simplified expenses method are:
- £18 per month (equivalent to £4.50 per week) if you work from home 25-50 hours per month.
- £26 per month (equivalent to £6.50 per week) if you work from home 51-100 hours per month.
- £34 per month (equivalent to £8.50 per week) if you work from home 101+ hours per month.
You simply multiply the appropriate monthly rate by the number of months you worked from home during the tax year. This method is best suited for those with relatively low expenses and a simple home office setup.
Actual Costs: Maximising Your Tax Relief
To calculate actual costs, follow these steps:
- Determine the business portion of your home: Calculate the percentage of your home used exclusively for work (e.g., room size).
- Gather household bills: Collect bills for heating, electricity, council tax, mortgage interest/rent, internet, and phone.
- Calculate the business portion of each bill: Multiply each bill by the business portion percentage.
- Add up the total business portion of all bills: This is your total allowable expense.
Record Keeping Requirements: Maintaining detailed records of all household bills and calculations is vital. HMRC may request this information if they investigate your claim.
Record Keeping: What Evidence Do You Need?
HMRC requires you to keep records for at least six years. Essential documentation includes:
- Receipts for all household bills.
- Detailed calculations showing how you apportioned costs.
- A record of the number of hours worked from home (if using the simplified expenses method).
- Invoices for any home office equipment purchased.
Both digital and physical records are acceptable. Using accounting software can greatly simplify record-keeping.
Claiming Home Office Tax Relief: How to Do It
You can claim home office tax relief in several ways:
- Self-Assessment: If you complete a self-assessment tax return, include the relevant expenses on your return.
- PAYE Adjustment: If you’re an employee, you can request a tax adjustment through your employer, or directly through HMRC if your employer doesn’t offer this service.
- Contacting HMRC Directly: You can contact HMRC directly to claim relief.
Important Deadlines: The deadline for submitting self-assessment tax returns is 31st January following the end of the tax year (e.g., 31st January 2027 for the 2025/2026 tax year).
Home Office Setup & Tax Relief: Can You Claim for Furniture?
Yes, you can claim for the cost of office furniture, but it depends on the item and its cost.
- Items costing £200 or less: You can claim the full cost as an expense in the year of purchase.
- Items costing more than £200: You’ll need to claim capital allowances. This allows you to deduct a portion of the cost each year over several years. The Annual Investment Allowance (AIA) allows you to deduct the full cost of qualifying assets up to a certain limit (currently £1 million, but subject to change).

FAQ
Q: What if I work from home sometimes, but not regularly?
You’re unlikely to be eligible for tax relief if your home working is infrequent and not a requirement of your job.
Q: Can I claim for the cost of a new broadband package if I’m working from home more regularly?
You can claim a proportion of the cost of your broadband package, based on the business use.
Q: What happens if HMRC rejects my claim?
You have the right to appeal HMRC’s decision. Gather any additional evidence to support your claim and follow the appeals process outlined on the HMRC website.

There’s no strict limit, but your claim must be reasonable and justifiable based on your actual expenses and the proportion of your home used for work.
