Finding out you’ve been entitled to money back from HMRC for years but have just never claimed it can be subtly annoying. The rules seem unclear and the amounts seem insignificant, not because the system is precisely hidden, but rather because no one told you. Many remote workers are familiar with that feeling.
What matters now is that you may be able to claim working from home tax relief going back four tax years if you have been forced to work from home as part of your job—not voluntarily, but truly required to do so. The weekly flat rate is £6. That works out to £1.20 a week at 20% basic rate tax. It doesn’t sound dramatic. However, when multiplied over a four-year period, it adds up, and the idea behind it is more significant than most people realize.
The eligibility line is the first thing to comprehend because it is more stringent than most people realize. If your employer doesn’t have an office and you must work from home, or if your job actually requires you to live too far away from an office to commute, you can make a claim. Choosing to work remotely is something you cannot claim, even if your employer is completely on board, even if you have been doing so for five years, and even if your winter heating bill is significantly higher. HMRC establishes and upholds the boundary between necessity and preference.
Millions of workers were temporarily permitted to make claims during the pandemic because the government was mandating that people stay at home. Silently, those regulations were reversed. Many employees might have been unaware of the change and continued to believe they were still qualified. They weren’t. The regulations did not become more stringent; rather, they reverted to their pre-Covid state.
The procedure is simpler than it was in the past if you do qualify. You can check your eligibility and make a claim using HMRC’s online tool. The claim is processed through that return for anyone who is registered with Self Assessment. The relief is applied to your tax code as an employee, so rather than being paid directly, it is reflected in your salary. If you’re claiming actual costs instead of the flat rate, you’ll need bills or receipts in addition to a note from your employer attesting to the requirement to work from home.
The majority of people will choose the flat rate option. No receipts other than evidence that you fulfil the requirement are required at £6 per week. You can claim the exact amount if your actual additional expenses—such as heating, business phone calls, and electricity for your workspace—amount to more than that. Documentation is needed for this, including phone records and utility bills. The flat rate is easier and still worthwhile for the majority of employees.
The timeline is one item that should be noted. HMRC has confirmed that employees will no longer be eligible for working from home tax relief starting with the 2026–2027 tax year. The current window is crucial because of this. It is still possible to file claims for the current year and up to four prior tax years, but this opportunity is limited.
The situation is a little different in Ireland. Employees who work from home can apply through myAccount to receive 30% of their electricity, heating, and broadband expenses under Revenue’s Remote Working Relief. Additionally, employers can contribute up to €3.20 per day, tax-free, towards those expenses. Both systems exist and go unclaimed more frequently than they ought to, but neither is particularly generous.
People seem to talk themselves out of this. The total appears modest. The form appears to be laborious. The regulations don’t seem clear. However, HMRC will not ask you to check or offer the funds. It only takes fifteen minutes and costs nothing to check your eligibility if you have been working from home due to necessity. That’s arguably the simplest tax advice available.
