How It Works
Employees who are required to work from home by their employer can claim tax relief on additional household costs. The simplest method is the flat-rate deduction of £6 per week (£312 per year) which does not require receipts. This gives a tax saving of £62.40 for basic-rate taxpayers or £124.80 for higher-rate taxpayers.
Alternatively, you can claim the exact additional costs of working from home — such as the proportion of your heating, electricity, broadband and phone bills attributable to work. This requires keeping records and calculating the business-use percentage. HMRC accepts a reasonable apportionment method.
Claims can be made through your employer (who adjusts your tax code) or via Self Assessment. You can backdate claims for up to four years. Note: you cannot claim if you choose to work from home — it must be a requirement of your job. This calculator shows the relief available under both the flat-rate and actual-cost methods.
Example: Higher-rate taxpayer, flat-rate claim
- Flat-rate claim: £6/week × 52 = £312/year
- Tax relief at 40%: £312 × 40% = £124.80 saving
- Or actual costs: £50/month extra heating/electric = £600/year
- Tax relief at 40% on actual: £600 × 40% = £240 saving
- Actual costs method saves £115.20 more but requires records
