3What this role really is

You design and build the technology solutions that keep a tax function running. This role covers systems architecture, integration, and creating new tools that solve real problems.

4What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

Thomson Reuters ONESOURCE (or Corptax, Vertex, Avalara) Expert

Configuring complex tax logic, building custom reports, managing user roles, troubleshooting calculation errors, and leading module implementations (e.g., Indirect Tax, Provision).

SAP S/4HANA (FI/CO) / Oracle NetSuite / MS Dynamics 365 Finance Advanced

Writing custom queries to extract tax-relevant data, defining requirements for 'tax sensitisation' of the ERP, and understanding end-to-end transaction flows and their tax impact.

Alteryx Expert

Designing and building complex, automated data transformation workflows from scratch for tax data preparation, reconciliation, and reporting. You'll be the go-to person for Alteryx solutions.

SQL Expert

Writing advanced SQL queries with multiple joins, subqueries, and complex logic to extract, transform, and validate tax data from various databases. You'll be comfortable optimising queries for performance.

Using Python for data manipulation, analysis, and automation tasks that go beyond what's easily achievable in Alteryx or Excel, especially for large datasets or complex statistical analysis for tax analytics.

Power BI / Tableau Advanced

Building complex, interactive dashboards for tax analytics (e.g., ETR analysis, cash tax forecasting, nexus tracking). This involves using DAX/LOD expressions for sophisticated calculations and presenting insights to tax leadership.

Advanced Excel (Power Query, Power Pivot, VBA) Expert

Automating complex reporting packages using VBA, building sophisticated financial models that integrate with external data sources, and establishing best practices for spreadsheet governance (while pushing for automation out of Excel).

5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Technical Architecture Design Follows pre-defined architecture, escalates deviations. Proposes minor architectural adjustments for specific projects, seeks approval. Designs and approves technical architecture for significant workstreams, consults Lead/Manager on cross-system impact.
Project Budget Allocation No budget authority, flags potential overruns to supervisor. Manages project expenses within a defined budget (e.g., £5K), escalates variances. Manages project budgets up to £25K, makes recommendations for larger expenditures to Lead/Manager.
Hiring for Direct Reports No involvement beyond interview feedback. Participates in interviews, provides feedback. Conducts technical interviews, provides strong recommendations for hiring.
Vendor Selection (Software/Consulting) No involvement. Researches vendor options, provides input on features. Evaluates vendor capabilities, participates in demos, recommends preferred vendors for specific projects.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Project Delivery & Automation Impact
Number of automation projects successfully delivered and the quantifiable reduction in manual effort.
Target · Successfully deliver 3-5 major automation projects annually, reducing manual effort by at least 300 hours per project.

Leading the implementation of a new indirect tax engine, which cut manual sales tax reconciliation time by 40% (roughly 500 hours annually) and reduced error rates by 75%.

System Stability & Uptime
Operational stability and reliability of critical tax technology systems under your purview.
Target · Maintain 99.9% uptime for core tax compliance and provision systems, with zero critical defects post-deployment for projects you lead.

After a major ERP tax sensitisation project, no critical tax-related system errors were reported in the first six months post-go-live, indicating robust design and testing.

Data Quality & Accuracy
Improvement in the accuracy and completeness of tax-relevant data across integrated systems.
Target · Reduce identified data discrepancies in key tax reports by 25% year-on-year, and ensure data lineage is traceable for all critical tax data points.

Designed and implemented a data validation routine that automatically flags inconsistent GL account mappings, reducing manual clean-up time by 20 hours per month and improving provision-to-return true-up accuracy.

Budget Adherence for Projects
Managing project costs within approved budgets for initiatives you lead.
Target · Deliver projects within a 10% variance of the approved budget (typically £50K-£500K).

Led a tax data mart build project with an approved budget of £150K, delivering it at £145K, demonstrating effective cost management.

Technical Leadership & Mentorship
Your ability to guide and develop junior team members, and to act as a technical authority within the team.
  • You'll be the first point of contact for complex technical roadblocks for your team. Junior analysts will proactively seek your advice. You'll lead regular technical deep-dives and knowledge-sharing sessions. We'll see clear growth in the technical capabilities of your direct reports over time.
Cross-Functional Collaboration & Influence
How effectively you work with IT, Finance, and other business units to get things done, often needing to influence without direct authority.
  • IT teams will recognise you as a reliable partner. You'll be invited to early-stage discussions on new ERP modules or system changes that might impact tax. Tax leadership will trust your technical recommendations. You'll be able to get different teams to agree on a common solution, even when their priorities clash.
Proactive Problem Solving & Innovation
Identifying potential issues before they become major problems and proposing innovative technical solutions.
  • You'll bring solutions to the table before a problem is formally raised. You'll propose new tools or methodologies that improve our tax processes. We'll see you researching and experimenting with new tech to address long-standing tax challenges, not just waiting for instructions.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Solving Complex Puzzles

You'll spend your days dissecting intricate tax calculations, unravelling convoluted data flows, and figuring out how to automate processes that seem impossible to non-technical tax professionals. It's a constant intellectual challenge.

Successfully designing and implementing a solution to automate the provision-to-return true-up process, which involved integrating data from three different systems and accounting for complex permanent vs. temporary differences.

Building Tangible Solutions

You'll get to build actual systems, workflows, and dashboards that directly improve the lives of your colleagues and reduce financial risk for the company. You'll see your work in action, making a real difference.

Creating a new tax data mart that becomes the 'golden source' for all tax reporting, eliminating hours of manual data manipulation for the entire tax team each month.

Technical Leadership & Mentorship

You'll guide and develop a small team of analysts, sharing your expertise and helping them grow. You'll be the technical authority for your domain, shaping how we approach tax technology.

Mentoring a junior analyst to independently build their first Alteryx workflow for VAT reporting, seeing them grow in confidence and capability under your guidance.

What frustrates people
  • The 'Excel is not a database' crusade: Constantly trying to persuade highly intelligent tax professionals to abandon their sprawling, multi-linked, macro-heavy spreadsheets that are the backbone of the department but are also a massive operational risk.
  • IT's 'Security Policy' Roadblock: Hearing 'no, we can't open that port' or 'no, that software isn't on our approved list' from IT, which often feels like a bureaucratic excuse to avoid dealing with a niche, complex finance application.
  • Being the 'Tax Helpdesk': The Head of Tax views you as a strategic automator, but the rest of the team sometimes sees you as the person to call when their VLOOKUP breaks or the printer won't work.
  • Last-Minute Law Changes: Spending six months building a perfect automation workflow, only for a new piece of tax legislation to render the logic obsolete weeks before go-live. It happens.
  • 'Garbage In, Gospel Out': The source data from sales or operations is a mess, but when your system produces a flawed tax result, everyone assumes your technology is broken, not the data it was fed. You'll spend a lot of time proving that point.
  • The UAT Quagmire: Users reporting 'bugs' that are actually features of the new, more efficient process, requiring you to spend more time on change management and training than on technical fixes.
What this role does not give you
  • A predictable, unchanging technical landscape – tax law and technology are always evolving.
  • A 'hands-off' approach to people management – you'll be actively mentoring and guiding your team.
  • A purely technical role – you'll need strong communication and influencing skills.
  • Immediate gratification on every project – some big builds take a long time to deliver value.

8Who you work with

This role directly shapes the efficiency, accuracy, and risk profile of our global tax function. Your designs and implementations will determine our ability to comply with tax laws, optimise our tax position, and defend our tax filings. Essentially, you're building the engine that drives our tax strategy, which has a direct impact on the company's financial health and reputation.

Inside the business
  • Tax Leadership (Head of Tax, Tax Directors)
  • Finance Systems Team
  • IT Infrastructure & Security
  • Controllership & Accounting Teams
  • Business Unit Finance Leads
Outside the business
  • External Auditors (PwC, Deloitte, EY, KPMG)
  • Tax Software Vendors (Thomson Reuters, Vertex, Avalara)
  • Consulting Partners (for major implementations)

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • A minimum of 8 years of dedicated experience in tax technology or a closely related finance systems role, with at least 3 years focused on leading projects or workstreams.
  • Demonstrable experience designing and implementing complex data integration and automation solutions using tools like Alteryx, SQL, or Python.
  • Proven track record of successfully leading at least two end-to-end tax technology implementation projects (e.g., tax engine, data mart, provision software).
  • Experience managing or mentoring junior analysts, including providing technical guidance and conducting code reviews.
  • A deep understanding of at least one major tax engine (e.g., ONESOURCE, Vertex, Corptax) and its configuration capabilities.
  • Solid grasp of financial accounting principles and how they relate to tax reporting (e.g., trial balance structure, GL accounts, basic tax provision concepts).

Working with AI on the job

Working with AI

Where AI is starting to help

Imagine cutting down on the tedious, repetitive parts of your job, freeing you up for the really interesting, strategic work. That's exactly what AI can do for a Lead Tax Technology Specialist. We're not talking about replacing you; we're talking about giving you a superpower.

In tax technology, AI isn't just a buzzword; it's a practical tool that can automate data classification, spot risks, process documents, and even let your tax colleagues query complex data in plain English. Here's a glimpse of how you'll be using AI to transform our tax function.

Automated Transaction Classification

AI will review millions of AP/AR transactions, intelligently suggesting the correct tax code or product category, and flagging ambiguous items for your human review. This drastically cuts down on manual data cleansing and ensures higher accuracy from the get-go. No more sifting through endless spreadsheets to fix miscoded items.

AI-Powered Risk & Opportunity Identification

Imagine an AI analysing historical audit findings, transactional data, and external legal databases to proactively identify high-risk areas (like potential nexus creation or incorrect exemptions) and pinpoint opportunities (such as unclaimed tax credits or refund claims). You'll get a heads-up on issues before they become problems, and find money we might be missing.

Intelligent Document Processing (IDP) for Audits

During an audit, AI can extract and structure key information from unstructured documents like tax authority notices, invoices, and legal contracts. It automatically populates audit defence workpapers and flags discrepancies, saving you and your team countless hours of manual review and data entry. It's like having a super-fast, tireless paralegal.

Natural Language Query for Tax Data

This is a game-changer. It allows tax professionals to ask plain-English questions—like 'What was our total sales tax paid in California for Q3?'—and get an immediate, accurate answer from the tax data mart, without needing to know SQL or run a complex report. You'll build the underlying systems that make this possible, empowering the whole team.
