What Are Payments on Account for Dentists?
Payments on Account are advance tax payments required by HMRC under the Self-Assessment system.
Dentists who are self-employed (particularly associates) often face large Payments on Account in their first year of trading — creating unexpected cash flow strain.
Why Do Payments on Account Matter for Dental Associates?
HMRC assumes your next year’s income will be similar to the last. This means associates must pay:
- Last year’s tax bill, plus
- 50% advance for the current year, and
- Another 50% advance mid-year.
Example:
- Year 1 tax bill = £12,000.
- Year 2 January: HMRC demands £18,000 (12k + 6k advance).
- Year 2 July: HMRC demands another £6,000.
- Total paid = £24,000 in one year — double the expected outflow.
Without planning, this can wipe out cash reserves or lead to overdrafts.
How Do Payments on Account Work?
| Date | What You Pay |
| 31 Jan | Previous year’s bill + 50% of next year |
| 31 Jul | 50% of next year |
| 31 Jan following year | Balance adjusted to actual liability |
Common Pitfalls for Dentists
- First-Year Shock – New associates don’t expect 150% payment in one go.
- Underestimating Growth – If year 2 income is higher, more tax is due on top of payments on account.
- Cash Flow Crunch – July payment often lands alongside summer holidays or slow diary months.
- Ignoring Superannuation – Pension contributions not factored properly into payments.
