Architects are able to reduce their taxable profit by claiming various expenses. Common allowable expenses include professional subscriptions (such as RIBA membership), software licenses (e.g. CAD programs), office supplies, and equipment. If you work from home, you can claim a portion of household bills. Travel costs to client sites are also deductible. Professional indemnity insurance is a key expense. It’s important to remember ongoing education costs and relevant books or publications. If you use a vehicle for business, log your mileage for claims. It’s crucial to keep all receipts and maintain detailed records. Some larger purchases qualify for capital allowances, so be sure to keep this in mind. Additionally, it’s important to differentiate between revenue and capital expenditure. The HMRC may investigate claims to ensure that all expenses are genuine and business-related.
