01 April 2025

As we step into the new tax year, payroll management for UK accounting firms is set to be more complicated than usual. With the legislative changes coming into effect, payroll accountants must position themselves as pivotal advisors to businesses navigating these new regulations.

However, with the industry’s ongoing recruitment challenges, many firms are considering payroll outsourcing as a strategic solution. But what does this mean for your practice? Should UK firms outsource payroll and is it right for your business?

Let’s delve into the pros and cons of outsourcing payroll for accountancy firms in today’s context.​

The Current State of Payroll Outsourcing in the UK

Outsourcing has become a cornerstone for many UK accounting firms aiming to enhance efficiency and capacity.

A recent report by Deloitte indicates that businesses spent over $700 billion on outsourcing in 2022, with projections suggesting this figure will continue to rise. Another study shows that outsourcing payroll saves costs for around 32% of SMEs, as they find it more affordable than managing payroll in-house.

The shifting trend is evident: when it comes to payroll outsourcing vs in-house payroll, accountants lean toward the former owing to growing benefits beyond just cost savings.

But what exactly are these benefits? Let’s explore payroll outsourcing benefits and risks for accountancy firms in 2025.

Pros of Outsourcing Payroll in 2025

1. Cost Efficiency

Managing payroll internally involves significant overheads, including software expenses, staff salaries, and ongoing training. By outsourcing, firms can reduce these costs, saving an average of £10,000/year per FTE and other related expenses. Cost savings with outsourced payroll is one of the primary reasons why accounting firms rely on external support.

Cons of Outsourcing Payroll and How to Mitigate Them

1. Loss of Control

Handing over payroll functions can lead to concerns about reduced oversight. To address this, establish clear communication channels and set expectations with your provider to maintain transparency.

2. Data Security Risks

Sharing sensitive employee information with a third party introduces potential security vulnerabilities. Ensure your chosen provider has robust data protection measures and complies with GDPR regulations.

3. Hidden Costs

While outsourcing can be cost-effective, be wary of additional fees for services like setup, pension auto-enrolment, or HR integration. For instance, setup costs may be around £2 per employee, with HR integration ranging from £10 to £25 per employee per month.

4. Dependency on External Providers

Relying heavily on an external partner may pose risks if the provider faces operational issues. Mitigate this by conducting thorough due diligence before engagement and having contingency plans in place.

The efficiency of outsourced payroll services depends on the provider you partner with. All the above risks can be eliminated by partnering with the best payroll outsourcing solutions UK.
