Tax careers in startups: the skills that set you apart in the UK market

The tech market across the UK is evolving quickly, and so is the nature of tax careers.

Startups are scaling at pace, navigating a more complex tax system and bringing tax professionals into the business much earlier in their growth journey.

For tax professionals, this creates a clear shift in expectations. Traditional experience in corporate tax or professional services is still valuable, but startups now need broader capabilities.

They want tax professionals who understand complex tax environments, can work with technology and offer practical, commercial advice.

At Brewer Morris, we’re seeing strong demand for candidates who can operate in these fast-moving environments. Here are the key skills that will set you apart if you’re exploring tax roles in startups.

Startups are hiring tax talent earlier

Historically, many small businesses relied on external tax advisers to manage corporate tax returns, indirect tax obligations and overall tax compliance. Today, startups are building in-house tax capability much sooner.

This is driven by:

• Increasing HMRC scrutiny and evolving tax law
• The impact of tax planning on fundraising and growth
• The need to manage tax liability and cash flow from an early stage
• Greater complexity in business tax and international tax structures

This means opportunities for tax professionals are opening up earlier, including roles at Tax Manager level within scaling businesses. However, candidates need to be comfortable owning processes and making decisions without the infrastructure of a large team.

Strong technical skills are still needed

Despite the shift towards more strategic roles, technical skills remain the foundation of any successful tax career.

Startups typically look for candidates with a solid grounding in:

• Corporate tax and business tax fundamentals
• Indirect tax, particularly VAT
• Employment tax and national insurance contributions
• Income tax and personal tax considerations
• Capital gains tax and equity-related planning
• International tax and global tax requirements (where applicable)

Professional qualifications such as ACCA supported by knowledge from bodies like CIOT, continue to carry strong weight.

Candidates who can interpret tax law and apply it to real-world scenarios will stand out, particularly in businesses dealing with complex tax issues.

Commercial thinking and problem-solving

One of the biggest differences between startups and traditional employers is the need for commercial awareness.

Startups value tax professionals who can:

• Translate technical tax obligations into business decisions
• Support senior stakeholders with clear, practical advice
• Manage tax obligations and ensure tax-efficient outcomes
• Build relationships with external advisors and authorities
• Solve problems quickly in environments where processes are still developing

Problem-solving is particularly important. You may not have access to large internal teams or detailed precedent.

Instead, you will need to rely on your judgement and ability to interpret the UK tax system in real time.

Technology, automation and AI

Tax functions are being transformed by tax technology. Automation, data tools and AI are becoming central to how startups manage tax compliance and reporting.

Candidates who stand out are those who can:

• Use Excel effectively to manage and analyse tax data
• Work with tax technology platforms to streamline processes
• Support initiatives linked to Making Tax Digital
• Improve efficiency in tax returns and reporting cycles

For many job seekers, this is an area where skills need to catch up with demand. Building exposure to automation and digital tools is increasingly important, particularly in tech-led environments.

Understanding the full tax lifecycle

Startups need tax professionals who can manage a broad range of responsibilities across the tax year.

This includes:

• Preparing and reviewing tax returns
• Monitoring taxable income and effective tax rate positions
• Supporting tax planning and forecasting
• Ensuring compliance with HMRC requirements

Unlike larger organisations, where roles may be highly specialised, startup tax roles often span multiple areas.

This breadth can accelerate learning, but it also requires confidence across different aspects of tax.

International and transfer pricing experience

As startups grow, many expand beyond the UK into international markets. This creates demand for candidates with international tax experience.

Key areas include:

• Transfer pricing
• Cross-border corporate tax structures
• Managing international tax compliance
• Understanding different tax systems and regulatory environments

Even limited exposure to these areas can make a candidate more attractive. Startups value individuals who can help them navigate expansion without relying entirely on external advisers.

The importance of cash flow and tax planning

In startups, tax is closely linked to cash flow. Managing a tax bill effectively can have a direct impact on how a business operates and grows.

As a result, tax professionals need to understand:

• How to forecast tax liability
• Timing of payments within the tax year
• Tax-efficient structuring of income and expenses
• Use of capital allowances and tax relief opportunities

This is where tax planning becomes particularly important. Candidates who can take a proactive approach rather than a purely compliance-focused mindset will stand out.

Employment tax and workforce complexity

As startups scale their workforce, employment tax becomes more complex. This is especially relevant in businesses that rely on flexible or global talent models.

In-demand skills include:

• Managing national insurance contributions
• Advising on self-employed and sole trader arrangements
• Understanding employment status and tax obligations
• Supporting international workforce expansion

These areas are often overlooked, but mistakes can lead to significant financial and reputational risk.

Why these skills are in demand

The demand for these capabilities is being driven by several factors:

• Increasing complexity in tax reform and regulation
• Greater pressure on businesses to maintain accurate tax compliance
• The rise of technology and automation within tax functions
• The need for strategic input from tax professionals in growing businesses

At the same time, there is a limited pool of candidates who combine technical depth, commercial awareness and digital expertise. This is why these skills are so highly valued in the current market.

How to position yourself as a candidate

If you’re considering a move into a startup tax job, there are several practical steps you can take:

• Strengthen your technical grounding across corporate tax, indirect tax and employmenttax
• Build exposure to tax technology and automation tools
• Develop commercial awareness by understanding how tax impacts business decisions
• Seek opportunities to work on international tax or transfer pricing projects
• Stay up to date with HMRC guidance and broader tax law developments

Candidates who can demonstrate adaptability and a willingness to learn are particularly attractive to startups.

Looking ahead

Tax careers in the UK are evolving, particularly within the tech sector. As startups continue to scale, the role of tax professionals will become even more strategic, combining compliance, planning and commercial insight.

For jobseekers, this represents a significant opportunity. Those who can develop a broad skillset, embrace technology and navigate complex tax environments will be well placed to succeed.
