How to claim work-from-home tax relief in 2026/27

Work-from-home tax relief tightened significantly after COVID. From April 2022 onwards, employees can only claim if their employer requires them to work from home — not if they merely choose to. The rules are different for self-employed people. Here's how to claim correctly and what you can actually expect.

6-minute read

For 2026/27, employees can claim £6/wk flat-rate (£312/yr) tax relief if their employer requires them to work from home. The relief is worth ~£62/yr at basic rate, ~£125/yr at higher rate. If you only sometimes work from home by choice, you don't qualify under the post-2022 rules. Self-employed people use simplified expenses (£10-£26/month based on hours) or proportional actual costs. You can backdate four years via form P87 (employees) or your tax return (self-employed).

Employee rules — 2026/27

You qualify if ALL of the following apply:

The COVID-era waiver expired.From April 2020 to April 2022, HMRC let almost any employee claim work-from-home relief because of COVID. That blanket waiver is gone. The pre-COVID test is back: required, not chosen.
Hybrid working usually doesn't qualify.If your employer has an office you could use, and you choose hybrid for convenience, you don't qualify even if your employer's policy says "work from home 2 days a week is fine". The test is whether the job genuinely requires home working.

How much relief and what it's worth

Your tax rateAnnual relief £6/wk × 52Tax saving
20% basic rate£312£62.40
40% higher rate£312£124.80
45% additional rate£312£140.40

You don't get £312 in your bank account — you get £312 added to your tax-free Personal Allowance, which reduces your tax bill by the rates above.

£6/wk flat vs actual costs

You can claim either:

Actual-cost calculation

Sarah works from home 3 days/wk in a dedicated room (10% of her home's floor area). Her gas + electric bill is £180/month.

  • Time apportionment: 3/7 days × 10/24 work hours = 1.79% of home use
  • Floor apportionment: 10% of bill = £18/month
  • Time-floor apportionment: 10% × 3/7 = 4.3% per month = £7.74/month = £93/yr
  • £6/wk × 52 = £312 is much better.Take the flat rate.
Broadband is excluded.You'd have broadband regardless of work — no proportion is allowable. Only direct work-from-home additional costs count (incremental gas/electric, business calls).

Step-by-step: claiming via P87

If you don't file Self Assessment, claim using form P87.

Step 1: Decide online or paperOnline (faster): gov.uk/tax-relief-for-employees has an interactive service that submits a P87 electronically. Paper: download form P87 and post to HMRC.
Step 2: Sign inThe online P87 needs Government Gateway sign-in. If you don't have one, you can still use the form via paper.
Step 3: Answer questionsHMRC asks: employer name, employer PAYE reference, your job role, why you need to work from home (job-required), the tax years you're claiming for, the £6/wk amount (or actual costs).
Step 4: HMRC processesHMRC adjusts your tax code to add £312 to your tax-free allowance for each tax year claimed. For prior years, HMRC issues a refund via your bank or by cheque. For the current year, you'll feel the benefit through reduced tax in payslips going forward.

Step-by-step: claiming via Self Assessment

If you already file SA, put the £312 (or actual amount) in SA102 box 20 ("Other expenses and capital allowances"). HMRC's automatic calculation gives you the relief.

Self-employed rules

Self-employed people don't use P87. They claim "use of home as office" on the SA103 self-employment supplementary page.

Hours/month worked from homeSimplified rate
25-50 hours£10/month (£120/yr)
51-100 hours£18/month (£216/yr)
101+ hours£26/month (£312/yr)

Or use actual costs (gas, electric, water, council tax, mortgage interest, repairs — proportional to business use). Most freelancers and sole traders find simplified is easier and HMRC enquiry risk is lower.

Backdate four years

You can claim work-from-home relief for the four previous tax years:

Be careful with 2021/22 and earlier.The COVID-era waiver applied — you may have already claimed via the special HMRC tool launched in 2020. Don't double-claim.

Worked example: 4-year backdated claim

Tom is a software engineer required to work fully remote since April 2022 (his employer closed its London office). He's never claimed WFH relief. As a higher-rate taxpayer:

  • 4 years × £312 = £1,248 total relief on his tax-free PA
  • Tax saved: £1,248 × 40% = £499 refund
  • Plus ongoing £125/yr from tax code adjustment

Common mistakes

Mistake 1: Claiming when you're hybrid by choice.If your employer offers hybrid working but doesn't require you to work from home, you don't qualify. HMRC may not flag this immediately but can ask later — keep an email from your employer confirming the home-working requirement if applicable.
Mistake 2: Claiming and then changing jobs.If your new role doesn't require home working, the relief should stop. Tell HMRC.
Mistake 3: Using a refund agency."Tax refund agencies" advertise WFH relief claims for a 20-30% fee. The claim is free via P87 — don't pay anyone.
Mistake 4: Confusing employee and self-employed routes.Employees use P87; self-employed use SA103. Some freelancers who also have employment incorrectly use SA for everything; this can under-claim.
Mistake 5: Forgetting reimbursed expenses.If your employer reimburses you for home-working costs (e.g. tax-free £6/wk via payroll), you can't claim again through P87. Check your payslip first.
