• across our US clients’ portfolios. This is a pivotal, client-facing role for

You will be the subject-matter expert who will build the operating

organizational goals. You will achieve this by collaborating across our

multi-jurisdictional teams (US, UK, Luxembourg, Ireland and Channel Islands) to

business and people growth, help develop the next generation of talent, and help

position Aztec as the golden source of investor tax data for our clients.

Key responsibilities

• Clients and Business Development

• Act as the US tax subject-matter expert for Investor Services, giving clients

confidence that Aztec can own and technically stand behind the investor tax

lifecycle.

• Support senior leaders in identifying, scoping and proposing new and expanded

tax service opportunities (e.g. end-to-end W-form review, K-1 data

preparation support, FATCA/CRS enablement).

• Work effectively within Aztec’s multi-service and multi-jurisdictional client

teams to ensure information is shared effectively and relationships are built

and maintained across US, UK,  Luxembourg, Ireland and Channel Islands.

• Build and maintain trusted relationships with clients’ in-house tax teams and

their external advisers, coordinating clear roles, hand-offs and SLAs

(e.g. with PwC) to eliminate ambiguity over ownership.

• Deliver high levels of client satisfaction across the Tax service client

base, proactively surfacing recommendations rather than waiting for

requests.

• Support the Tax leadership and Business Development team in the pricing of

new tax services opportunities and pilot programs.

Operations

• Technical tax form review: Perform and review technical, end-to-end review of

W-8/W-9 forms – moving beyond completeness checks to accuracy, tax

classification, withholding implications and expiry tracking – embedding this

into the onboarding and periodic review process.

• Data ownership & golden source: Take ownership of investor tax data capture

at onboarding, ensuring Aztec holds clean, structured, validated tax

attributes (books & records) that can be shared with clients’ advisers,

reducing reliance on manual data scraping.

• K-1 collection & tracking: Drive the acceleration and automation of K-1

collection, validation and tracking (partnering on tools such as Aztec

Xtract) to move away from manual, Excel-based processes and improve capture

rates and turnaround.

• Tax refund check controls: Own and strengthen the control framework for US

tax refund check tracking, including a single-source tracker, clear status

tracking (outstanding / received / deposited / written off),

custody, reconciliation and 4-eyes review.

• Tax & payments: Oversee tax payment processing and support evaluation of

automated tax payment solutions, improving cash visibility, forward-looking

payment notification and escalation timing between clients, advisers and the

US team.

• FATCA / CRS: Support and scale Aztec US involvement in FATCA/CRS processes,

partnering with technology to handle volumes through automation.

• Coordinate with clients’ third-party advisers and tax authorities, and act as

a technical escalation point for the wider Investor Services and US team.

• Coordinate with client’s auditor/tax preparer as needed, assist on ad-hoc

projects and unusual notices (e.g. proactively monitoring for items such as

IRS Form 8986).

• Maintain appropriate records of our clients’ tax affairs, the work we provide

on their behalf and associated filings, ensuring continuity year over year.

• Consistently and comprehensively deliver Aztec’s internal control framework

and processes, and build the process work flows, documentation, deadline

calendars, FAQs and operating memos that embed US tax knowledge across the

team.

Governance and Change

• Contribute to Group and/or jurisdictional-specific Tax service projects,

as required, including the design of Aztec’s future tax operating model.

• Partner with the technology and transformation teams to embed digital tax

data capture, automated validation and regulatory/tax reporting into our

platforms.

• Establish and maintain robust governance with clients and their advisers –

defining SLAs, hand-offs, responsiveness expectations and quarterly service

reviews – and ensure global alignment across all jurisdictional teams.

• Support the design of pilots and enhanced operating models, clarifying the

division of responsibilities between Aztec and clients’ external tax

advisers.

Skills, knowledge, expertise

• 8+ years of relevant tax experience, ideally within alternative investments /

private markets, funds or fund administration (partnership tax, investor tax

reporting, FATCA/CRS).

• Strong technical knowledge of investor tax documentation (W-8/W-9), K-1s,

withholding, state tax payments and refund processes.

• A Big 4 / public accounting background is desirable; relevant professional

qualification (e.g. CPA / EA) is desired.

• A relevant undergraduate degree (Accounting / Finance / Business).

• Experience building or improving processes, controls and documentation – with

the credibility to be the technical sign-off and to stand behind Aztec’s work

with clients and their advisers.

• A data-driven, technology-forward mindset – comfortable

partnering on automation and data-extraction initiatives to reduce manual

effort and risk.

• The ability to work collaboratively with diverse, multi-jurisdictional client

teams and to coordinate effectively with external advisers.

• Attention to detail to ensure the delivery of consistent and high standards,

particularly in high-risk, control-sensitive areas.

• Excellent organizational, communication and people skills, with the ability

to translate technical tax matters for non-tax stakeholders.

• A commitment and desire to deliver high levels of client service, and to help

develop the next generation of talent.

• Ability to think critically and creatively, and to work under pressure within

tight, deadline-driven tax cycles.
