Why accountants should outsource payroll in the UK to a global expert like Accace Adept: Navigating rising costs and multi-jurisdiction compliance

Accace Adept - outsource payroll in the UK

For many accountancy firms, payroll has quietly become one of the most demanding services to deliver. It is operationally heavy, highly regulated and increasingly exposed to risk. Yet clients expect it to run flawlessly, every single month.

As regulatory pressure grows and employer costs rise in the UK, more accountants are reassessing whether payroll still makes sense to manage in-house. The reality is that payroll today requires constant legislative monitoring, specialised systems and local expertise, especially when clients operate across borders.

This is where a dedicated payroll service for accountants comes into play. By outsourcing payroll in the UK to a global expert such as Accace Adept, accounting firms can protect margins, reduce compliance risk and free up capacity for higher-value work.

Payroll has changed – and so have the risks for accountants

Payroll is no longer “routine”

Payroll used to be predictable. Today, even relatively small clients may employ staff in multiple countries, hire remote workers or move quickly between growth phases. Each of these scenarios introduces new payroll obligations, reporting rules and statutory deadlines.

For accounting firms, this means payroll is no longer a standardised process. It is a complex compliance function with real financial and reputational consequences if something goes wrong.

Regulatory pressure keeps increasing

In the UK, payroll legislation continues to evolve. The planned increase in Employers’ National Insurance Contributions (NIC) from April 2025 is only one example. When combined with frequent changes to employment rules, reporting obligations and international payroll regulations, the compliance burden on in-house teams becomes significant.

For many accountants, keeping payroll compliant across jurisdictions now requires specialist knowledge that sits outside their core expertise.

The impact of rising Employers’ NIC on accounting firms

More scrutiny, more questions from clients

Higher employer costs inevitably lead to more client questions. How will this affect payroll budgets? What can be optimised? Are calculations correct? Can payroll errors be avoided?

Accountants remain responsible for the accuracy of payroll, even when margins are tightening and workloads are increasing.

Internal payroll teams feel the pressure

Rising NIC costs do not just affect clients. They also increase the cost of running payroll internally within an accounting firm. Skilled payroll professionals are harder to recruit and retain, systems require ongoing investment and compliance errors carry higher consequences than ever before.

This is why many firms are turning to an outsourced payroll service for accountants that is built specifically to handle scale, complexity and change.

Why accountants are outsourcing payroll in the UK

Reduce compliance and operational risk

Payroll errors can damage client trust and expose accounting firms to penalties or disputes. Outsourcing payroll to a global specialist significantly reduces this risk. Dedicated payroll providers focus exclusively on compliance, ensuring calculations, filings and reporting meet all local and international requirements.

This allows accountants to step away from day-to-day payroll risk while maintaining confidence in the outcomes.

Free up internal capacity

Payroll consumes time, often disproportionate to its profitability. Month-end pressure, corrections, client queries and legislative updates drain resources that could be better used elsewhere.

By outsourcing payroll, accountants can release internal capacity and redirect it towards advisory services, client development or strategic work that generates higher margins.

Access specialist payroll technology

A modern payroll service for accountants is underpinned by automation, secure data handling and real-time reporting. These systems reduce manual work, limit errors and improve transparency for both accountants and their clients.

Building and maintaining this level of payroll infrastructure internally is expensive. Outsourcing gives accountants immediate access without long-term system investment.

Scale without adding headcount

Client portfolios change. Some clients grow internationally, others restructure or downsize. A global payroll provider can absorb these changes quickly, without forcing accounting firms to expand or restructure their own teams.

This flexibility is especially valuable for firms supporting growing or internationally active clients.

Cost control and commercial clarity

Manage rising payroll-related costs

Outsourced payroll providers operate at scale, spreading expertise and system costs across many clients. This often results in lower overall costs compared to maintaining an in-house payroll function, particularly when international payroll knowledge is required.

As Employers’ NIC increases take effect, this efficiency becomes a key advantage.

Predictable pricing

A professional payroll service for accountants typically offers clear, transparent pricing models. This gives accounting firms cost certainty and helps avoid unexpected expenses linked to staffing, training or system upgrades.
