Small employers usually choose between group dental insurance, a health cash plan that refunds part of dental bills, or paying towards a dental practice's own membership plan. In most cases HMRC treats employer-funded dental cover as a taxable benefit in kind: if you pay the provider directly, you report it on a P11D and pay Class 1A National Insurance on its cost.
Dental care is one of the more tangible perks a small business can offer. It is used regularly, it is easy for staff to understand, and unexpected dental bills are a common worry. But the options work quite differently, and the tax and payroll treatment depends on how you pay, so it is worth understanding both before you commit.
Some local practices make this simpler by offering a monthly plan that covers routine care. For example, St Peter's Lodge, a dentist St Albans employers can look at, publishes the details of its membership plan online, which shows the kind of information you should look for when comparing a practice plan with an insurance or cash plan product.
What are the main types of dental benefit?
There are three broad routes, plus the simplest option of contributing cash. Each suits a different kind of team.
| Option | How it works | Points to consider |
|---|---|---|
| Group dental insurance | An insurer covers a set range of treatment, usually up to annual limits, at practices of the employee's choice or within a network | Check waiting periods, exclusions for existing problems and annual caps |
| Health cash plan | Staff pay their dental bills, then claim back a set amount or percentage up to a yearly limit; often covers optical and other everyday costs too | Refund limits can be modest; check what counts as dental |
| Practice membership plan | A monthly fee to a specific practice, or a plan provider working with it, covers routine check-ups and hygiene visits, sometimes with treatment discounts | Tied to one practice; staff must be accepted as patients there |
| Cash allowance or reimbursement | You pay staff extra, or refund receipts, towards dental costs | Flexible, but treated as earnings through payroll |
Remember that NHS dentistry is still an option for many staff, with fixed band charges in England. Some employees may prefer a benefit that helps with NHS charges, while others already use a private practice and would value a plan there.
How does HMRC treat dental benefits?
GOV.UK's guidance on medical or dental treatment and insurance says that what you need to report and pay depends on the kind of treatment or insurance you provide and whether you pay the provider directly. Dental cover is generally not exempt. The exemptions listed include one health screening or medical check a year, certain eye tests and glasses for screen work, and treatment or insurance related to injuries or diseases caused by the employee's work. Routine dental cover does not fall into these categories.
The guidance sets out three main scenarios:
- You arrange and pay the provider directly. Report the benefit on form P11D and pay Class 1A National Insurance on its value.
- Your employee arranges the cover and you pay the provider. Report it on a P11D and add the value to the employee's earnings for Class 1 National Insurance through payroll. GOV.UK says no PAYE tax is deducted through payroll on this route.
- You reimburse the employee. The payments count as earnings, so you deduct PAYE tax and Class 1 National Insurance through payroll. A cash allowance or extra salary for medical costs is treated the same way.
The value of the benefit is the cost to you of providing it, or the amount you reimburse. Salary sacrifice arrangements are not exempt; GOV.UK says that if the cost is lower than the salary given up, you report the salary amount instead.
The employee pays income tax on the benefit value through their tax code, so it is worth explaining this when you introduce the perk. A benefit that costs you a set amount a year will reduce the employee's take-home pay slightly, even though it is still usually good value.
What are the reporting deadlines?
For benefits reported on P11D, GOV.UK lists these deadlines after the end of each tax year:
- 6 July: report expenses and benefits to HMRC, give employees a copy of the information, and report the total Class 1A National Insurance you owe.
- 22 July: pay Class 1A National Insurance (19 July if paying by cheque).
If you payroll benefits instead of using P11D, the tax is collected monthly through payroll. Your payroll provider or accountant can confirm which method you use.
How do I choose the right option for my team?
Start with the people, not the product. A few questions help:
- Where do staff live and work? A practice plan suits a team based in one town; insurance or a cash plan suits a spread-out or remote team.
- Do staff already have a dentist? Many people are reluctant to switch. Cash plans and most insurance let them stay where they are.
- What is your budget per head? Compare annual cost per employee, including Class 1A National Insurance, not just the headline monthly price.
- Who is eligible? Decide whether part-time staff, new starters and family members are included, and put this in writing.
- What happens when someone leaves? Check whether cover ends immediately and whether the employee can continue it personally.
Your checklist before launching a dental benefit
- Asked staff whether they would value dental cover and how they currently pay.
- Compared at least one insurance, one cash plan and one practice plan.
- Read the exclusions, waiting periods and annual limits in writing.
- Worked out the total cost per head, including Class 1A National Insurance.
- Decided whether you will pay providers directly or reimburse staff.
- Confirmed the reporting method with your payroll provider or accountant.
- Written a short policy covering eligibility, leavers and how to claim.
- Explained to staff that the benefit is taxable and how it appears on their tax code.
A local example
For an employer in St Albans, a local practice plan is one option to compare. St Peter's Lodge Dental Practice on Adelaide Street describes itself as a family-run private practice and offers a practice membership plan run by Denplan. Its website lists two levels: Essentials, from £24.15 a month, covering regular check-ups, routine X-rays when needed, up to two hygiene appointments a year and up to 10% off treatments not covered by the plan; and Care, from £29.05 a month, which adds fillings and extractions, treatment for gum problems and a discount on crowns. The practice says interested patients should call to enquire, so an employer would need to confirm directly whether and how a business could fund places for staff.
Frequently asked questions
Is employer-paid dental insurance tax-free?
Usually not. Unless it relates to an injury or disease caused by the employee's work, GOV.UK treats it as a reportable benefit, normally on P11D with Class 1A National Insurance.
Can I offer dental cover through salary sacrifice to save tax?
GOV.UK says salary sacrifice arrangements for medical or dental treatment or insurance are not exempt, so they still need to be reported.
Do I have to offer it to every employee?
There is no single rule for this in the tax guidance, but you should apply consistent, written eligibility criteria and take advice on employment law if unsure.
What value goes on the P11D?
The cost to you of providing the treatment or insurance, or the amount you reimbursed.
