Working From Home Tax Relief Calculator (UK)
From 6 April 2026, employees can no longer claim working from home tax relief from HMRC. You can still backdate claims of £6 per week for 2022/23 to 2025/26 if you had to work from home — this calculator shows how much you could get back for each year.
The government removed employees' right to claim tax relief for extra household costs of working from home from the 2026/27 tax year, announced at the November 2025 Budget. HMRC found more than half of the claims it checked were not eligible. Employers can still pay you up to £6 a week (£312 a year) towards these costs without tax or National Insurance.
For earlier years the flat rate was £6 a week, with relief at your tax rate: a basic-rate taxpayer gets £62.40 for a full year and a higher-rate taxpayer £124.80. You can claim for the 4 previous tax years (2022/23 to 2025/26), but only if you had to work from home — for example because your employer had no office. You cannot claim if you chose to, or if your contract simply let you.
To claim for a past year, use HMRC's online service and send evidence that you were required to work from home. If you file Self Assessment, claim through your tax return instead.

Working From Home Tax Relief – What You Need to Know
Who Can Claim Working From Home Relief
The relief was removed for employees from 6 April 2026, but you may still claim for 2022/23 to 2025/26 if your employer required you to work from home – whether full-time or just a few days per week. The key requirement is that you must work from home, rather than simply choosing to. However, HMRC says you cannot claim if you chose to work from home, including where your contract lets you or the office is sometimes full. Self-employed workers cannot claim this relief (they deduct home office costs differently through Self Assessment).
Flat Rate vs Actual Costs
The flat-rate method let you claim £6 per week (£312/year) for 2025/26 and earlier years, with evidence that you had to work from home. Alternatively, you can claim actual additional costs – the increase in your heating, electricity, metered water, and business calls directly attributable to working from home. This requires evidence (comparing bills before and after home working) and must be claimed via Self Assessment. For most employees, the flat rate is simpler and often provides similar value.
How to Claim from HMRC
The fastest route is HMRC's online portal at gov.uk. You'll need a Government Gateway account (free to set up). For past years HMRC refunds the tax owed back to you. Claims for 2026/27 are not possible. If you file a Self Assessment return, you can include the claim there instead. You can also call HMRC directly, though phone wait times can be long during January–April. Remember, you can backdate claims up to 4 years, so it's worth checking if you missed previous years.
