How to deal with imposter syndrome as a tax leader

As organisations continue to strengthen their in-house tax capabilities across the Netherlands, many professionals have recently been promoted into management and leadership positions.

These promotions are often well deserved, but they can also trigger imposter syndrome.

Many newly promoted tax leaders find themselves questioning whether they’re ready for the role, despite years of experience and a strong track record.

If you’ve recently stepped into a leadership position and you’re experiencing self-doubt, you’re not alone.

Imposter syndrome is particularly common among high achievers, especially during periods of career progression and change.

Here’s how to deal with imposter syndrome as a tax leader.

What is imposter syndrome?

Imposter syndrome is the feeling that your success is not fully deserved and that others may discover you’re less capable than they believe.

First identified by psychologists Suzanne Imes and Pauline Clance, imposter syndrome affects professionals across industries and levels of seniority. It’s particularly common among ambitious professionals who continually set high standards for themselves.

For tax leaders, imposter syndrome often appears after a promotion.

Rather than focusing on the experience and expertise that earned them the opportunity, they focus on perceived gaps in their knowledge or leadership experience.

Why promotions can trigger self-doubt

Many tax professionals spend years developing technical expertise. But after a promotion, expectations change.

Success is no longer measured only by technical knowledge. Leaders are expected to manage teams, influence stakeholders, contribute to business strategy and lead through change.

This shift can create persistent self-doubt, particularly for professionals who are used to being the subject matter expert in the room.

Common concerns include:

• Feeling unprepared for a leadership role
• Comparing yourself with more experienced leaders
• Experiencing a fear of failure when making decisions
• Worrying that others overestimate your abilities
• Struggling to accept positive feedback

Why tax professionals are particularly vulnerable

The tax profession attracts individuals who are analytical, detail-orientated and driven. While these qualities contribute to success, they can also increase the likelihood of imposter syndrome.

Many tax professionals have perfectionist tendencies. This can be valuable when dealing with compliance and technical tax issues, but leadership often requires making decisions without having complete information.

As responsibilities increase, perfectionism can lead to feelings of inadequacy, particularly when combined with negative self-talk and unrealistic expectations.

Research by Dr. Valerie Young identifies several common patterns of imposter syndrome. Recognising these can improve self-awareness and help you understand your own behaviours. They include:

• The perfectionist focuses on flaws rather than achievements and believes anything less than perfect is failure
• The natural genius expects immediate success and becomes discouraged when learning new skills requires time and effort
• The soloist believes asking for support demonstrates weakness and feels they should solve every challenge independently

Many tax leaders will recognise aspects of themselves in at least one of these categories.

Signs imposter syndrome is affecting your leadership

The signs of imposter syndrome are not always obvious. In many cases, they appear as behaviours that look productive on the surface but are driven by insecurity.

Some common signs include:

• Downplaying achievements
• Overpreparing for meetings and presentations
• Reluctance to delegate work
• Constant comparison with peers
• Difficulty accepting praise
• Negative self-talk after setbacks

Recognising these behaviours is the first step towards addressing them.

How to overcome imposter syndrome

The aim isn’t to eliminate every moment of self-doubt. Even experienced business leaders experience periods of uncertainty. The goal is to stop those feelings from affecting your confidence and performance.

Focus on evidence

When imposter syndrome appears, look at the facts.

Think about the reasons you were promoted. Consider the projects you have delivered, the teams you have supported and the challenges you have overcome.

Many professionals remember mistakes far more clearly than successes. Keeping a record of achievements, successful projects and stakeholder recognition can help create a more balanced perspective.

Challenge negative self-talk

Negative self-talk can quickly reinforce feelings of inadequacy.

When thoughts such as “I’m not qualified for this role” arise, ask yourself what evidence supports that statement. Most newly promoted leaders would never judge a colleague as harshly as they judge themselves.

Replacing assumptions with facts can significantly reduce persistent self-doubt over time.

Stop expecting perfection

Leadership isn’t about getting every decision right. It revolves around making informed decisions, learning quickly and helping others succeed.

Many professionals struggle because they continue to hold themselves to the standards of their previous technical role. Successful leaders understand that progress is often more valuable than perfection.

Accepting that mistakes and learning curves are part of growth can make imposter syndrome much easier to manage.

Seek mentorship and support

Mentorship can be a valuable way to overcome imposter syndrome. Speaking with experienced tax leaders often reveals that many have faced similar challenges after promotions or career transitions.

Some professionals also benefit from working with a leadership coach to strengthen self-awareness and build confidence in their leadership style.

Don’t let self-doubt lead to burnout

One of the biggest risks associated with imposter syndrome is burnout.

Professionals who constantly feel they need to prove themselves often take on too much work, avoid delegating and hold themselves to unrealistic standards. Over time, this can have a negative impact on both performance and mental health.

Confidence rarely arrives the moment you receive a promotion. It develops through experience, learning and exposure to new challenges.

If you’ve recently secured a promotion within the Dutch tax market, remember that your organisation recognised your expertise, leadership potential and ability to add value. Trust that judgement and give yourself permission to grow into the role.
