The Role
We have an opportunity for a motivated, inquisitive, and detail-oriented Tax Analyst to join our tax team.
As a Tax Analyst, you will support the tax team across a broad range of UK and international tax matters, with a primary focus on tax reporting, compliance, data analysis, and operational tax processes, alongside opportunities to support advisory and project work. The role is hands-on and deadline-driven, reflecting statutory reporting and tax requirements. Whilst predominantly direct tax focused, you will also support indirect tax matters, enabling you to build a broad, well-rounded, and commercially relevant tax skillset.
The role is ideal for an early-career tax professional looking to develop their tax technical expertise and experience across tax disciplines. Working closely with experienced tax professionals across the team, you will work in a collaborative team environment and benefit from regular guidance, mentoring, and support.
Our tax function is evolving to meet the challenges of a fast-paced, dynamic, and growing international business whilst strengthening capabilities in response to increasing governance, compliance, and control requirements. As a result, this role offers an exciting opportunity to develop alongside the business, gaining greater exposure to increasingly complex tax matters and taking on greater responsibility as your career progresses.
Key Responsibilities:
Direct Tax
- Assist with gathering and preparing data required for global corporate tax returns and other direct tax filings (such as withholding tax returns), liaising with the finance team.
- Maintain the global compliance calendar to ensure all filing, payment, and other regulatory obligations are met on time.
- Assist with the preparation of the UK R&D tax credit claim, including extracting and analyzing data from finance systems.
- Support the roll forward, preparation, and standardization of interim and year-end tax reporting calculations.
- Assist with Transfer Pricing compliance, such as documentation and quarterly calculation reviews.
Indirect Tax
- Assist with the preparation of periodic indirect tax returns, both UK and international.
- Produce, analyze, and validate data to support the monthly US sales tax returns and other indirect tax compliance, including the EU EC Sales List, One Stop Shop, and Intrastat filings.
- Verify and maintain customer sales tax exemption certificates.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
