Can I Claim Dental Work as a Business Expense?

Dental treatment is firmly in the category of personal expenditure as far as HMRC is concerned. Your limited company cannot pay for dental work as a tax-free business expense, regardless of the circumstances. However, there are ways to structure dental benefits through your company that, while not tax-free, can still be financially advantageous.

If your company pays for your dental treatment directly, the cost is treated as a Benefit in Kind. This means the company gets Corporation Tax relief on the payment (it is a deductible staff cost), but you as the director pay income tax on the value of the benefit, and the company pays Class 1A National Insurance at 13.8% on the benefit value. For a 40% taxpayer, a £500 dental treatment paid by the company would cost you £200 in income tax plus £69 in employer NI, though the company saves £125 in CT relief.

Dental insurance is a more structured approach. Your company can take out a dental insurance policy for employees and directors. The premiums are tax-deductible for the company and constitute a Benefit in Kind for the individual. Typical dental insurance costs £15-30 per month per person and covers routine check-ups, hygiene appointments, and a proportion of treatment costs. The BIK tax on a £25/month policy (£300/year) would be £120 for a 40% taxpayer, which is still cheaper than paying for private dental care out of taxed personal income.

The one exception that sometimes catches directors' attention is the trivial benefits exemption. Under this rule, your company can provide benefits worth up to £50 each without a BIK charge, provided they are not cash or cash vouchers, not a reward for services, and not in the employment contract. While you could not structure a course of dental treatment this way, a £50 dental check-up could theoretically qualify as a trivial benefit. However, this is a stretch and should not be relied upon as a regular arrangement.

For directors comparing options, the most tax-efficient approach to funding dental care is usually to extract money from the company via the most efficient route (pension contributions, salary up to the NI threshold, then dividends) and pay for dental care personally. Company-funded dental insurance makes sense primarily when offered to all employees as part of a benefits package, as it aids recruitment and retention.
