The pandemic fundamentally changed how Britain works. Three years on from the return to offices, hybrid working has become the default arrangement for millions of employees across the UK. According to the Office for National Statistics, around 28% of working adults now split their time between home and the office, and another 16% work from home full time. That is a combined 44% of the workforce doing at least some work from their kitchen table, spare bedroom, or home office.
With so many people working from home regularly, you would think the tax relief rules would be straightforward. They are not. HMRC tightened the criteria after the pandemic-era relaxation, and many people who claimed during 2020–2022 would no longer qualify. Here is a clear guide to where things stand in 2026.
The Fundamental Rule: Required, Not Chosen
The single most important distinction is this: you can only claim working from home tax relief if your employer requires you to work from home. Choosing to work from home for convenience, even if your employer permits it, does not qualify you for the relief.
During the pandemic, this requirement was effectively met by default because the government told everyone to work from home. HMRC accepted claims almost without question. That era is firmly over. Since the 2022/23 tax year, HMRC has returned to the pre-pandemic interpretation, and claims are being scrutinised more carefully.
You are likely to qualify if:
- Your employment contract states your home is your primary workplace
- Your employer has no office or desk available for you
- You live too far from the nearest office to commute reasonably, and your employer has agreed to home-based working
- Your role requires you to work from home on specific days (documented in writing)
You probably do not qualify if your employer has office space available and you choose to work from home under a flexible working arrangement. The word "choose" versus "require" is everything in HMRC's eyes.
What Can You Claim?
If you do qualify, there are two routes:
The flat-rate method: Claim £6 per week (£312 per year) without needing to provide any evidence of actual costs. At the basic tax rate, this saves you £62.40 per year. At the higher rate, £124.80. It is not a fortune, but it requires minimal effort.
The actual-cost method: Calculate the proportion of your household bills (electricity, gas, water, broadband) attributable to your work. This requires more record-keeping but can yield a larger deduction, particularly if you have a dedicated home office and work from home full time. You will need to calculate the proportion based on the number of rooms used for work and the hours worked.
Our working from home tax relief calculator lets you compare both methods side by side, so you can see which gives you the better result for your specific circumstances.
What You Cannot Claim
There are several common misconceptions about what counts as a claimable expense:
- Rent or mortgage payments: These are not claimable because you would pay them regardless of whether you work from home
- Council tax: Same principle — it does not increase because you work from home
- General furniture: A new sofa for your living room is not a work expense, even if you sometimes sit on it while on conference calls
- Broadband (entirely): You can only claim the proportion of your broadband bill attributable to work use. If you use it for personal streaming 80% of the time, you cannot claim the whole bill
Equipment that your employer does not provide and that you need exclusively for work — a second monitor, an ergonomic chair, a headset — may be claimable separately under the general employment expenses rules. The key word is "exclusively" — if the item is used for both work and personal purposes, HMRC is unlikely to allow the full cost.
How to Make the Claim
For employees, the claim is made through HMRC's online portal. If your total employment expenses (including working from home relief) are under £2,500, you can use the P87 form. If they exceed £2,500, you will need to file a self-assessment tax return.
You can backdate claims for up to four previous tax years. So if you qualified in 2022/23, 2023/24, and 2024/25 but never claimed, you can still do so now. That could be worth up to £374 for basic-rate taxpayers or £749 for higher-rate taxpayers across three years using the flat-rate method.
If you are self-employed rather than an employee, the rules are different. You claim use-of-home expenses as part of your self-assessment, either using HMRC's simplified expenses method or by calculating the actual proportion. Our self-employed tax calculator includes home office deductions in its calculations.
The Employer Allowance Alternative
Some employers pay a tax-free working from home allowance directly. HMRC allows employers to pay up to £6 per week (£26 per month) without requiring evidence of actual costs and without it counting as taxable income. If your employer already pays you this amount, you cannot also claim the tax relief — that would be double-dipping.
If your employer pays you less than £6 per week, you can claim the difference through HMRC. And if they pay you nothing, the full £6 per week relief is available (assuming you meet the eligibility criteria).
Check your payslip for any working from home payments. If you are not sure whether your employer provides an allowance, ask your HR or payroll department. For a complete picture of how all your deductions interact, run your salary through our salary calculator and check your tax code to ensure it reflects any allowances correctly.
Is It Worth the Hassle?
For the flat-rate claim, absolutely. It takes about ten minutes to submit a P87 form online, and the saving — while modest — is money you are entitled to. For actual-cost claims, it depends on the amount. If you work from home full time in a dedicated office, the claim could be worth several hundred pounds, making the record-keeping worthwhile. If you work from home one day a week at your kitchen table, the flat rate is likely your best and easiest option.
The important thing is to be honest about your eligibility. HMRC has been issuing more enquiries into working from home claims since 2023, and an incorrect claim can result in penalties. If you genuinely meet the criteria, claim with confidence. If you are in the grey area, err on the side of caution.
