Working From Home Tax Relief UK: Claim Your Allowance

Working from home has become a permanent fixture for many across the UK, bringing with it both flexibility and a host of new expenses. From increased heating bills to extra electricity usage, the costs can add up. Thankfully, HMRC offers working from home tax relief UK to help offset some of these expenditures.

This comprehensive guide will walk you through everything you need to know about claiming this relief, ensuring you don't miss out on what you're entitled to. We'll cover who is eligible, what you can claim for, how to make a claim, and answer some common questions.

What is Working From Home Tax Relief?

Working from home tax relief, often referred to as 'working from home allowance' or 'home working expenses', allows employees to reclaim a portion of the additional household costs they incur by working from home. It's not about claiming for your commute or lunch, but specifically for the extra money you spend on things like heating, electricity, and internet because your home is now also your workplace.

The relief is designed to compensate for the legitimate increased costs where your employer requires you to work from home, or where there are no appropriate facilities at your usual workplace.

Who is Eligible for Working From Home Tax Relief?

Eligibility for working from home tax relief UK depends on specific criteria set by HMRC. It's not available to everyone who works from home; there are key conditions you must meet:

• You must be an employee: Self-employed individuals claim their expenses differently through their self-assessment tax return.
• You must be required to work from home: This is the crucial point. It means your employer requires you to work from home, or your job necessitates it (e.g., no office available, or it's too far away). You generally cannot claim if you choose to work from home when an office is available.
• Your employer does not pay your expenses: If your employer already reimburses you for the additional costs of working from home, you cannot claim tax relief on those same costs.

The 'Required to Work From Home' Criterion

This condition can sometimes cause confusion. HMRC's official guidance states that you can only claim if you have to work from home, for example, because:

• Your employer does not have an office.
• Your employer has an office, but it's not practical for you to work there (e.g., it's too far away).
• The terms of your employment contract state you must work from home.

Simply preferring to work from home or your employer allowing you to work from home does not typically qualify. However, during the height of the COVID-19 pandemic, HMRC relaxed this rule, allowing claims if you were advised to work from home. For most current claims, the 'required to work from home' rule applies as described above.

What Can You Claim For?

When claiming working from home tax relief UK, you can claim for 'allowable expenses'. These are the additional costs you incur directly because you're working from home. You cannot claim for things you would pay for anyway, even if you weren't working from home.

Allowable expenses generally include:

• Heating and electricity: The increase in your bills due to keeping your home warmer or using more lights and powering your equipment during working hours.
• Internet access: The additional cost of having a broadband connection, or an upgrade specifically required for work. You cannot claim for the basic cost of broadband if you would have it anyway.
• Business phone calls: The cost of calls made for work purposes from your personal phone.
• Water (in some cases): If your water usage has significantly increased due to work (e.g., showering after a messy work task at home), this might be allowable, but it's less common.

You cannot claim for:

• Fixed costs: Rent, mortgage payments, council tax, or water rates (unless specifically increased due to work).
• Phone line rental: Unless it's solely for business use.
• New equipment: Such as a laptop or printer. These are usually your employer's responsibility. If you bought specific equipment for work and your employer hasn't paid you back, you might be able to claim capital allowances or a deduction, but this is a separate process.

How Much Can You Claim?

HMRC offers two main ways to claim working from home tax relief UK:

1. Flat Rate Allowance (Simplified Expenses)

This is the most common and easiest way to claim. Without needing to keep detailed records of your actual expenses, you can claim a flat rate allowance.

• £6 a week (or £26 a month) from 6 April 2020 onwards.
• For previous tax years: £4 a week (or £18 a month) before 6 April 2020.

This flat rate covers all your additional costs. You do not need to provide proof of your expenses. To calculate the total, simply multiply the weekly rate by the number of weeks you worked from home during the tax year. For example, if you worked from home for 52 weeks in a tax year, you could claim £312 (£6 x 52).

Example Calculation:

If you worked from home for 30 weeks in the 2023-2024 tax year, your claim would be:

30 weeks * £6/week = £180

This £180 is then deducted from your taxable income. The actual cash refund you receive depends on your tax rate:

• Basic rate (20%) taxpayer: You would get 20% of £180 back, which is £36.
• Higher rate (40%) taxpayer: You would get 40% of £180 back, which is £72.

2. Actual Costs

If your additional expenses are greater than the flat rate, you can claim for the actual amount. However, this requires meticulous record-keeping.

To claim actual costs, you must be able to demonstrate:

• Proof of expenditure: Keep all receipts for increased electricity, gas, or internet bills.
• Proof of additional cost: You'll need to show how much more you spent compared to when you weren't working from home. This can be complex, often requiring you to work out the proportion of your bills that relate to your work usage.

For example, if your average electricity bill was £50 before working from home and rose to £70 after, you could claim for the £20 increase, multiplied by the number of months. You might also need to factor in how many hours a day you use certain appliances for work against total household usage.

Given the complexity, most people find the flat rate claim much simpler and sufficient for their needs.

How to Claim Working From Home Tax Relief UK

The process for claiming working from home tax relief UK is relatively straightforward, primarily done through HMRC's online services.

Claiming Online for the Current Tax Year (or previous 4 years)

If you have never claimed employment expenses before, or haven't claimed for this tax year:

1. Visit GOV.UK: Search for 'claim tax relief for job expenses' or navigate directly to the relevant HMRC page.
2. Use your Government Gateway account: You'll need a Government Gateway user ID and password. If you don't have one, you can create one during the process.
3. Complete the online form: Follow the instructions. You will be asked questions about your employment, your reason for working from home, and the period you wish to claim for.
4. HMRC processes your claim: Once submitted, HMRC will adjust your tax code to reflect the allowance for the current tax year. This means you'll pay slightly less tax each month through PAYE. For previous tax years, they will send a one-off payment directly to you.

Important: If you claim for a previous tax year and you're eligible, HMRC will usually send you a cheque or pay directly into your bank account.

Claiming via Self Assessment

If you already complete a Self Assessment tax return, you should claim your working from home expenses through this method.

• Go to the 'Employment' section of your Self Assessment form.
• Enter the amount you are claiming (either the flat rate or your calculated actual costs) in the 'Expenses' box.

What if I've claimed before?

If you successfully claimed the flat rate allowance online for a previous tax year, your tax code might have been adjusted automatically for subsequent years. You should check your PAYE coding notice to see if 'Expenses' is listed. If it is, you don't need to do anything further for that year, as the relief is already being applied.

If your circumstances change (e.g., you stop working from home), you should inform HMRC.

Comparison: Flat Rate vs. Actual Costs

Feature	Flat Rate Allowance (£6/week)	Actual Costs
Proof Required	None	Detailed receipts for all additional expenses
Calculation	Weeks worked from home x £6	Proportional calculation of increased bills due to work usage
Ease of Claim	Very easy, simplified online process	Complex, requires diligent record-keeping and calculations
Max Claim Potential	Up to £312 per tax year (based on 52 weeks)	Potentially higher than flat rate if actual costs are very significant
Common Use Case	Most employees, when additional costs are modest or undeterminable	Employees with exceptionally high additional costs (e.g., specialist equipment heating)

For the vast majority of employees claiming working from home tax relief UK, the flat rate allowance is the preferred and most practical option.

What if My Employer Pays a Working From Home Allowance?

Some employers choose to provide their own working from home allowance to help with costs. If your employer pays you a non-taxable homeworking allowance, you cannot claim tax relief for the same expenses through HMRC for those costs.

As of the 2024/25 tax year, employers can pay up to £6 a week (or £26 a month) as a tax-free homeworking allowance to employees who work at home under an arrangement with their employer. If your employer pays more than this tax-free amount, the excess may be taxable.

If your employer pays less than the £6 a week, you may be able to claim tax relief on the difference with HMRC. For example, if your employer pays you £3 a week, you could claim relief on the remaining £3 a week from HMRC.

Important Considerations and Tips

• Claim on time: You can claim for the current tax year and the previous four tax years. Don't delay, as claims older than four years will generally not be accepted.
• Be honest: Only claim for expenses you genuinely incur and for periods you were genuinely required to work from home. HMRC takes tax evasion seriously.
• Keep records (if claiming actuals): If you opt for claiming actual costs, keep all relevant bills and proof of payment for at least six years after the end of the tax year to which they relate.
• Check your tax code: After making a claim, especially for the current year, check your PAYE coding notice. Ensure the allowance has been applied correctly. If not, contact HMRC.
• Don't forget other expenses: Working from home tax relief is just one type of employment expense. If you incur other work-related costs (e.g., professional fees, mileage), remember to check if you can claim for those separately.

Conclusion

Working from home tax relief UK is a valuable benefit for eligible employees, helping to ease the financial burden of increased household bills. While the amounts may seem small on a weekly basis, they can add up over a tax year, returning a welcome sum to your pocket.
