We'll only calculate your tax deduction for the months you worked from home.
Impact of Using a Room Solely for Business
Be aware that dedicating an entire room in your home exclusively for business use could affect your Capital Gains Tax (CGT) liability. This may result in a reduction in your CGT relief.

How to Claim the Work From Home Allowance
Claiming this allowance is simple:

  1. Calculate your Work From Home expense using an approved method.
  2. Add the calculated figure to your total business expenses when completing your next self-assessment tax return.
  3. Keep detailed records of how the calculation was made for compliance purposes.

Understanding 'Use of Home as Office' Claims
If you're self-employed and work from home occasionally, you may be eligible to claim a portion of your household expenses as business expenses, potentially lowering your tax bill.

There are two ways to calculate this:

  1. Reasonable Method: Often results in greater savings compared to the simplified expenses method.
  2. Simplified Expenses Method: Uses flat rates set by HMRC.

Why You Should Keep a Record
HMRC may request evidence of your calculation, so it’s essential to retain accurate records. Emailing a copy to yourself or your accountant is a good practice.

Who Can Use This?
This allowance and calculator are specifically for UK-based self-employed individuals.

Make sure to leverage this allowance to maximise your tax savings while staying compliant.

What is Work From Home Allowance?

Work From Home Allowance refers to a tax relief or financial reimbursement provided to employees who work from home. It is designed to help offset the additional costs incurred while working remotely, such as increased utility bills, internet usage, and other home office expenses.

In the UK, employees who work from home either full-time or part-time may be eligible to claim tax relief on certain expenses if their employer does not already reimburse them. The allowance is meant to ensure that individuals are not out of pocket for work-related costs incurred as a direct result of working from home.

What costs can I claim when working from home?

When working from home, you may incur additional household expenses directly related to your work. HMRC allows you to claim tax relief on some of these expenses, but only the portion used for business purposes. This ensures that you’re not out of pocket for the costs associated with maintaining your home workspace.

Here’s a breakdown of the main costs you can claim using the reasonable method approach:

  • Heating
  • Electricity
  • Council Tax
  • Mortgage Interest or Rent
  • Internet and Telephone Use
  • Repairs and maintenance

You can’t claim for the parts of these bills that are used for private or domestic purposes. For example, if you use a room in your home as an office for 30% of the time, you could only claim for 30% of the heating costs attributed to that room.

What is the ‘Simplified Method’ of calculating Working From Home Tax Relief?

The Simplified Expenses Method allows you to claim tax relief for using your home for business by applying flat rates based on the hours you work from home each month.

This method is easy to use but may not reflect your actual costs, potentially resulting in a smaller tax saving compared to the more precise Actual Cost Method, which calculates claims based on specific expenses.

What is the ‘Actual Cost’ method?

The Actual Costs method calculates the proportion of your home used for business and applies it to your actual bills.

For example:

If your home has 4 rooms, and you use 1 as an office 50% of the time, with a £400 electricity bill, your claim would be:
£400 × 1/4 × 50% = £50.
Include your ‘main’ rooms, like bedrooms, living rooms and kitchens (but not hallways or bathrooms).

Calculations can get tricky, but our Working From Home Calculator simplifies it all. Just ensure you keep records and evidence of your expenses for HMRC.
