Working From Home Tax Relief calculator 2024
Calculate work from home expenses for filing your Self Assessment Tax Return to HMRC
If you’re a sole trader working from home, you can claim back some of the costs you incur, like council tax, heating, lighting, phone calls and broadband when you file your Self Assessment Tax Return. We’ve made a calculator to help you calculate what you can claim back.
Fill in the information about your home office
Describe your home office
Provide a reasonable description of the spaces at your home that you work from. Keep in mind that you need to be able to explain your reasoning to HMRC if they decide to contact you to check your self assessment report.
About your property
For the number of rooms, count every separate room you have that can be described as a “normal living space”. This includes a living room, a kitchen, the bedrooms – but doesn’t include bathrooms and toilets.
About your monthly outgoings
Fill in any regular expenses you pay for your home – electricity, gas, rent or mortgage, and anything else. Add or remove the missing or not applicable expenses.
Percentage of rooms used for your business
How much of each of the rooms’ space do you use for your business? If you don’t use a room for business, leave the value at 0%
The estimated monthly cost to your business
This is how much you can claim tax relief on based on the information you’ve entered.
This is only a guide, so please contact us if you have any questions.

How does ANNA's Work From Home Calculator for Sole Traders work?
- We’ll ask you about your property:
- How many hours worked at home per day

- We’ll ask you about your monthly outgoings:
- Mortgage interest or rent paid per month
- Electricity bill
- Gas bill
- Council tax bill per year
- Phone (landline and mobile) and internet costs/year
- Buildings and contents insurance/year
- Building maintenance and repair/year
- Cleaning and cleaning services/year
- We’ll ask you what percentage of each room in your house you use for your business – you just enter or adjust the percentages.',
- Then let our calculator do the work and you’ll see the estimated amount we think you’ll be able to claim back.
What is the ‘Actual Cost’ method?
- If you own a catering business and sometimes use your home kitchen for trying out recipes, you might say that 15% of your home kitchen is used for your business needs.
- If you’re a photographer and have a separate studio room and and a dark room at home – and you don’t use those rooms for anything else – then each of those rooms is 100% business.
- If you live in a studio apartment and have a designated home office area, a rough percentage of the room’s area will be the one you indicate as used for business.
