What is the Average Cost for a Good Payroll Accountant?

Payroll is one of the most important admin tasks of any business. Employees expect to be paid by their companies on time, correctly and with full compliance. Many businesses see Payroll as a simple admin task. They might think that the cost of payroll is just about software subscriptions or the time the staff spends running it.

But payroll carries hidden costs that every business owner must know to avoid paying extra money. These hidden costs can drain budgets, increase risks and consume management time.

Here, we will discuss what payroll actually costs, where businesses lose money and how you can make payroll more cost-effective without losing its efficiency.

Understanding Payroll Charges

Payroll charges are the total expenses an employer incurs to compensate their employees, which include both the amounts withheld from an employee’s pay and additional costs paid by the employer. They cover more than just gross salary and can be broken down into direct and indirect costs.

Why Payroll Costs Are More Than Just Salaries And Software?

You might think that payroll is a fixed cost that includes buying software and hiring a payroll clerk. But this is just a small part of the cost of payroll. Payroll also includes compliance, accuracy and technology. A single error can activate HMRC fines, which can cost you extra money. The errors in the payslip can upset employees or damage trust.

The hidden costs of payroll do not appear on your balance sheet directly. They show up in the time wasted or when you change staff.

Direct Payroll Costs

The final cost of payroll is directly influenced by your business’s size, operational model, and employee locations. The most easily identified payroll costs include: 

• Salaries and wages: The most fundamental and obvious expense is the total compensation paid to employees for their work.
• Employer payroll taxes and contributions: Statutory payments that employers must make, including Employer’s National Insurance contributions, the Apprenticeship Levy, and workplace pension contributions.
• Software subscription fees: Fees for payroll software, which can be tiered based on employee count or charged at a flat monthly rate.
• Outsourcing fees: For companies that use a third-party payroll provider, fees can vary based on the number of employees, pay frequency, and the specific services included. Common pricing models include a per-employee, fixed, or tiered fee.
• Internal administrative costs: The direct cost of payroll or HR staff whose salaries are explicitly linked to managing the payroll function. 

Hidden Charges of Payroll

To save money, businesses should be aware of the often-overlooked hidden costs that arise from inefficiency and error. These indirect expenses can significantly impact your bottom line. 

• Penalties and fines: Incorrect tax filings, late submissions to HMRC, or missed payments can result in substantial penalties. For example, late payment of PAYE can trigger escalating fines and interest charges.
• Costs of miscalculated payslips: Fixing payroll errors consumes valuable staff time and can significantly impact employee morale and trust. Poorly handled mistakes can increase the risk of higher staff turnover, leading to additional recruitment and training costs.
• Administrative inefficiencies: Processes that rely on manual data entry, outdated systems, or a lack of employee training can lead to wasted time and resources. These inefficiencies, though not appearing on a monthly invoice, act as a drag on productivity.
• Costs of outsourcing providers: Additional and sometimes unexpected fees may be charged by payroll providers for services beyond the basic package. These can include setup fees, fees for correcting errors, or costs for services like advanced reporting and special payroll runs.
• Employee turnover: Errors and general dissatisfaction with payroll can lead to a higher turnover rate. The expense of hiring, onboarding, and training a new employee is a significant hidden cost. 

Payroll Management Options

Running Payroll in-house

Most small businesses manage their payroll internally. This option gives them control. But, this also comes with risks like human error, compliance pressure and time drains.

Its costs usually includes:

• Buying software licences
• Installing the hardware and software in office
• Maintain and upgrade the in-office payroll infrastructure

Outsourcing to a provider

You can hire a specialist to deal with payroll in your business. It mostly costs a monthly fee, but reduces internal workload and compliance risks.

Its cost consists of:

• Payroll processing fees that include employee wage calculations, payslips, HMRC submissions, and legal payments.
• Costs for compliance and reporting services that include pension auto-enrolment, tax filings, and year-end reporting.
• Fee for employee self-service portals, data security, and integration with HR or accounting systems.

Cloud-based solutions

Cloud software provides you with automation, remote access, and easy updates. However, they still need human oversight to check for any errors.

Its cost includes:

• A fixed fee for implementing software. It depends on how many employees you have and their regions
• Salaries to internal staff required for implementation, like HR, IT and project management teams

Tax Implications of UK payroll (2025–26)

The UK payroll tax system has significant implications for businesses, particularly with the 2025–26 tax year bringing notable changes to employer costs. Hidden costs can also erode profitability, but these can be minimised through strategic management and automation. 

Employers are responsible for deducting and paying a variety of taxes and contributions, which directly impacts staffing costs. 

Employer National Insurance Contributions (NICs)

• Rate increase: For the 2025–26 tax year, the main employer NICs rate will increase from 13.8% to 15%. This applies to earnings and most taxable benefits provided to employees.
• Secondary threshold decrease: The annual earnings threshold at which employers start paying NICs will drop from £9,100 to £5,000. This means employers will incur NICs on a larger portion of their payroll, particularly impacting businesses with many part-time or lower-paid staff. 

Employee taxes and deductions

• Income tax: Employers must deduct Income Tax from employee wages via the Pay-As-You-Earn (PAYE) system. Tax bands and rates for England, Wales, and Northern Ireland are currently frozen, while Scotland has its own tiered rates.
• Employee NICs: Employees also pay Class 1 NICs on their earnings, and employers must deduct this from their pay.
• Other deductions: Employers are also responsible for deducting and paying contributions for:
  • Automatic enrolment workplace pensions.
  • Student loan repayments.
  • Court orders and other statutory deductions. 

Employment Allowance

• Increased relief: To help offset rising employer NICs, the Employment Allowance has increased from £5,000 to £10,500 from April 2025. This allows eligible businesses to reduce their annual employer NICs bill.
• Expanded eligibility: The £100,000 eligibility cap on the allowance is now removed, meaning more businesses can benefit from the relief. Rules for connected companies and sole directors still apply.

Average Cost for an Accountant

For general accounting services, a UK accountant typically charges an hourly rate or a fixed monthly fee.

• Hourly Rates: A basic accountant’s hourly rate ranges from £25 to £60 per hour, while specialists may charge more.
• Monthly Fees: Many firms offer fixed monthly packages starting from under £50 per month for small businesses, which can include annual accounts and bookkeeping. 

Average Payroll Costs

The cost for payroll services is often based on the number of employees, with most providers charging on a per-employee, per-month basis.

• Per Employee: Outsourcing payroll for a small business (under 10 employees) typically costs between £4 and £10 per employee, per month.
• Monthly Payroll Costs: For a small business with 1–8 employees, the average monthly cost for a provider is between £25 and £60. This can rise to £75 to £250 per month for a business with 11–20 employees. 

Cost of Outsourcing Payroll

Outsourcing payroll can be a cost-effective alternative to hiring an in-house specialist, who would command a salary of £20,000 to £45,000 per year. The total cost of an outsourced service depends on whether you opt for a fully or part-managed solution.

• Fully Managed Payroll

This comprehensive option covers all payroll tasks and costs around £5 to £10 per payslip, per month, or £25 to £50 per month for a small business with 5 employees. Additional costs may include setup fees and pension auto-enrolment charges.

• Part-Managed Payroll

This hybrid service, where some tasks are handled in-house and others are outsourced, is cheaper at around £3 to £5 per payslip, per month, or £15 to £25 per month for a small business with 5 employees. However, consider the additional costs of in-house payroll staff and software.

How To Choose The Right Payroll Provider?

Outsourcing payroll is mostly cheaper in the long run than in-house payroll. Prices are different. But many UK providers charge £50–£200 per month. The cost depends on company size and services required. Outsourcing offers predictable costs and scalability for growing businesses.

Here’s how you can choose the right payroll provider for your company:

• You must find a provider with a proven UK client portfolio and positive reviews.
• You should ask the provider about data encryption, GDPR compliance, and cyber protection measures.
• You should choose a solution that grows with you. Payroll must scale without issues, even if you hire five or fifty more staff.
• Know that cheapest isn’t always best. You should analyse reporting tools, employee self-service portals, and integration with HR systems of the provider.

Bottom Line

Payroll is far more than a monthly admin task. It is an important function with hidden costs that businesses can’t afford to ignore. Well-managed payrolls in companies can budget more effectively, reduce risks, and strengthen employee trust. 

A smart payroll strategy will save money, and it will also improve accuracy, compliance with HMRC, and staff’s trust.  Most importantly, organised payroll frees owners to focus on business growth rather than struggling with payroll issues.
