For many dentists, career progression brings longer hours, greater responsibility, and higher earnings. But for a growing number of practitioners earning over £100,000, that progression can come with an unexpected consequence: less money in their pocket at the end of the month.
While specialisms and increased workloads are often expected to deliver greater financial security, the reality for some higher-earning dentists is more complex. In particular, dentists earning over £100,000 and raising children can experience increased financial pressure rather than relief.
This issue is most commonly seen among dentists operating as Sole Traders where income cannot be sheltered in a corporate structure.
The £100,000 income threshold
When an individual’s adjusted net income exceeds £100,000, a series of tax-related changes are triggered. Whilst this applies across every profession and industry, dentists can feel the impact more acutely as associate income often skitters due to holidays, the sporadic nature of big-ticket treatments, et cetera. Hence, some cross the threshold without realising they actually have done so!
For those entering this higher income bracket, the consequences can include:
- Reduced access to free childcare hours (subject to certain criteria, children are entitled to 1,140 hours per year of childcare funded by the government, from the academic term after their 9-month birthday)
- Ineligibility to Childcare Choices where the government ‘tops-up’ paid childcare on an 80:20 principal.
- Higher effective marginal tax rates
- The tapering or loss of certain personal allowances and tax benefits
Individually, these changes might seem manageable. Taken together, however, they can result in a situation where earning more actually reduces take-home pay.
What Dental Elite is seeing
Dental Elite is increasingly seeing dentists actively managing their income to avoid breaching the £100,000 threshold. In some cases, principals are delaying dividends, restructuring income, or even reducing clinical sessions to avoid triggering higher marginal tax rates or losing access to childcare support.
Because dentists’ income structures are often more complex that salaried roles, the effects of crossing income thresholds can be felt more sharply. Without forward planning, higher earnings can quickly translate into higher stress rather than greater financial security.
Children and households
Although Child Benefit is paid per household, the tax charge itself is calculated based on the highest individual earner as is eligibility for childcare funding, rather than combined household income. This can create stark differences between families with similar overall earnings.
This impact is often compounded by childcare costs, which frequently peak at the same stage in the dentist’s career when income rises above £100,000. With long clinical hours making childcare essential, reduced access to support can offset pay increases almost immediately.
When the threshold is exceeded, certain childcare support schemes can be restricted or become entirely inaccessible. This, alongside the higher tax exposure, can place families with higher earnings under financial pressure despite headline earnings appearing strong.
Marginal tax effects
The income range between £100,000 and approximately £125,000 is commonly described as a marginal ‘tax trap’. Within this band, additional income can be taxed at a significantly higher effective rate than many expect.
This can be particularly challenging for dentists whose income fluctuates due to dividend timing, bonus payments, or changing workloads. In some cases, practitioners only become aware they have crossed the threshold when the tax year ends, leaving little opportunity to mitigate the impact.
Proactive planning, not reactive decisions
Despite the thresholds and changes, there is still plenty that individuals can do to support their family more predictably. Understanding how income thresholds operate and planning around them early can significantly reduce surprises later in the year.
For dentists approaching or exceeding £100,000, planning discussions with accountants may involve:
- Reviewing the timing and structure of dividend payments
- Assessing the balance between salary and dividends
- Ensuring any family members employed by the business are in genuine roles that are paid a reasonable market value salary
Each of these steps require professional advice to remain compliant, which can be supported by working with professional assistance.
“This is no longer a niche issue,” Dental Elite notes. “As earnings rise across parts of the profession, more dentists are having to make strategic decisions not just about how much they earn, but when and how that income is taken.”
Timing matters
With the new tax year beginning on 6 April, it poses a perfectly positioned point for dental professionals to review their financial situation and make the necessary amendments to their specific circumstance. Early planning grants greater control and helps to avoid surprises later in the year.
Income planning should not sit in isolation. For many dentists, decisions around pay dividends and workload are increasingly tied to broader questions of sustainability, family life, and long-term career planning.
