Sole Traders, Partnerships and HMRC
HMRC has started a new campaign targeting sole traders and partnerships, checking that expenses claimed in self-assessment returns are properly adjusted for private use. If you’re self-employed, it’s worth paying attention; mistakes can trigger unnecessary questions or even penalties.
The focus is on disallowable expenses (especially costs that are partly personal). Think cars, phones, and similar items where you use them for both business and private purposes. For example, if you spend £2,200 on car costs and only 8,000 of the 14,000 miles are business, HMRC expects you to adjust the private portion proportionally.
It’s not just cars and phones, either. Business entertainment, travel, or marketing expenses can also come under scrutiny if they include personal use. The safest approach is to be clear and consistent in your calculations and records.
Tips to stay on HMRC’s good side:
- Keep detailed records for items like mileage or phone use. Don’t just copy last year’s figures.
- If you account for private use before filling in your tax return, explain it in the additional information section.
- HMRC accepts reasonable estimates where precise calculation is tricky (for example, home office costs or phone use). Using simplified expenses for homeworking can help avoid disputes.
In short, make sure you understand HMRC’s rules on private use, check each tax return carefully, and adjust expenses appropriately. Unsure or just want a friendly, helping hand? Give Rustrick Accountants a call on 01622 738165!
