Claiming Home Office Expenses for Your UK Side Hustle: What You Need to Know

Side hustles have become a common way for people in the UK to boost their income. Whether you’re a freelancer crafting brilliant designs, an online seller shipping handmade goods, or a consultant juggling spreadsheets on weekends, you might already be working from the comfort of your home. But did you know that if your side hustle is run from home, you could claim home office expenses to reduce your tax bill?

It's true—you can claim these expenses, provided you meet specific conditions set by HMRC. This guide will break down everything you need to know about claiming home office expenses for your UK side hustle in a simple and approachable way. Let's get started!

What Are Home Office Expenses?

Home office expenses are costs related to using your home as a workspace. These expenses can include a portion of your household costs that directly support your business operations.

Examples of Claimable Costs:

• Rent or Mortgage Interest – A portion of your housing cost attributed to your workspace.
• Utilities – Gas, electricity, water, and other bills necessary for the smooth running of your home office.
• Broadband and Phone Bills – Anything spent on keeping your business connected.
• Office Supplies and Software – Items like stationery, printers, or business-specific software subscriptions.

By claiming these costs, you can reduce your taxable income—helping you keep more of the money you earn from your side hustle. However, only eligible costs directly tied to your business use can be claimed.

For more guidance, HMRC's website explains in detail which expenses are allowable for self-employed individuals and side hustlers.

Who Can Claim Home Office Expenses?

To claim home office expenses, HMRC has specific criteria you need to meet. Here’s how to determine if you’re eligible:

HMRC’s Criteria:

• The space in your home must be used for business purposes, either exclusively or partially.
• You must perform clear business-related activities from home, such as administration, client communication, inventory management, shipping products, or conducting virtual classes.

Side Hustle Examples:

You can potentially claim home office expenses if you:

• Write blogs or design graphics as a freelancer.
• Manage and ship products for an ecommerce business.
• Teach courses or host tutoring sessions as a self-employed tutor.
• Run an online consulting business and meet your clients virtually.

If you’re working from home to fuel your side hustle, you’re likely eligible to claim.

Methods for Calculating Home Office Expenses

HMRC provides two main methods for calculating your home office expenses, depending on how much detail you want to go into.

1. Flat Rate Method

This is the easier, simplified way to claim without getting bogged down in calculations.

• How it Works: HMRC allows you to claim a fixed monthly amount based on the number of hours you work from home.
• Rates:
  • For 25-50 hours/month, claim £10/month.
  • For 51-100 hours/month, claim £18/month.
  • For 101+ hours/month, claim £26/month.

This method works well for those with relatively low household costs or who don’t want to deal with the hassle of precise calculations.

2. Actual Costs Method

This method involves more effort but could yield higher claims if your home office costs are significant.

How it Works:

Calculate the proportion of your household costs attributable to your business use by determining how much of your home is used for work purposes. This may include calculating the percentage of square footage used for your office or the time you spend working from home, helping you allocate expenses like utilities, rent, or mortgage accordingly.

Use the formula:

*]:!bg-transparent ring-1 ring-inset ring-indigo-200/80""><pre><code>**(Total annual expense) × (Percentage of home used for business) × (Percentage of time used for business).**</code></pre>

• Example Calculation:
  • Total annual electricity bill = £1,200.
  • Workspace = 10% of your home, used for business 50% of the time.
  • Claimable Amount = £1,200 × 10% × 50% = £60.

What Can’t You Claim?

Not all home expenses are claimable. Here are some items that HMRC excludes from home office claims:

• Personal Costs – Such as household repairs or rent/mortgage payments unrelated to your business.
• Non-Business Internet or Phone Use – If you’re using services for personal purposes, that portion cannot be included.
• Dedicated Spaces Without Dual Use – Be cautious with exclusive-use areas, as they may impact tax advantages later (more on this below).

To stay compliant, ensure you only claim for costs genuinely related to your business.

Common Pitfalls to Avoid When Claiming Home Office Expenses

Navigating HMRC’s rules can be tricky, but avoiding these common mistakes will help you stay on track:

1. Overclaiming

Claiming personal-use items like your entire internet bill could result in an audit. For details on staying compliant, refer to Gov.uk's guidelines.

2. Lack of Documentation

Keep detailed records of all calculations and supporting documents for at least six years.

3. Misunderstanding the Rules

Exclusive-use spaces may impact tax relief when selling your home. To learn more about potential implications, check HMRC's official resources or speak with a tax professional.

Tax Implications of Claiming Home Office Expenses

Claiming home office expenses can help reduce your taxable income. However, be cautious of lasting effects, such as potential liability for Capital Gains Tax on portions of your home if declared exclusively for business use.
