Are you building a home office? What you need to know.




As home working becomes more common, many people are considering building a dedicated office space at home. Whether it’s converting a spare room, an attic, or even constructing an office in the garden, there are important tax considerations to keep in mind. Understanding these will help you make informed decisions and maximise potential reliefs. Let’s take a look at a few of these implications.

When you build or convert a space into a home office, you might be able to claim capital allowances on the cost of certain fixtures and fittings. However, it’s important to note that the structure of the building itself generally doesn’t qualify for capital allowances. Instead, you can claim against the cost of assets such as desks, chairs, other office furniture, electrical wiring, heating and lighting.

The key point to remember? Always keep detailed records of all expenses to make accurate claims.

You can also claim tax relief on some of the ongoing running costs of your home office. These include utilities, internet, and even a portion of your mortgage interest or rent. However, the claimable amount must be proportionate to the amount of your home used for business purposes.

Building an office at home can have implications for Capital Gains Tax (CGT) when you sell your property. Normally, your main home is exempt from CGT under the Principal Private Residence (PPR) relief. However, if part of your home is used exclusively for business, that portion may not qualify for PPR relief, potentially leading to a CGT liability on the sale of your home.

If you’re VAT registered, you may be able to reclaim VAT on some of the costs associated with building and maintaining your home office. This could include VAT on construction costs, materials, equipment and running expenses. These would need to be adjusted in line with the proportion that relates to personal use compared to the business use.

If your home office is considered a separate business premises, you might be liable to pay business rates. This typically applies to offices that are entirely separate from the main house, such as a garden office. However, in many cases, small businesses can qualify for small business rate relief, potentially reducing or eliminating the liability.

Building a home office can provide a practical solution for your business needs, but it’s important to navigate the tax landscape carefully. From capital allowances and running cost reliefs to the potential for CGT and business rates, there are several factors to consider. Consulting with an accountant can help ensure you maximise available reliefs while avoiding unexpected tax liabilities.
