Key takeaways

• Choose HMRC-recognised payroll software to automatically handle Real Time Information submissions, tax code updates, and year-end reporting, which protects your business from penalties that can reach £10,000 per day for missed pension duties.
• Calculate the true cost of manual payroll by adding up the hours spent on data entry, tax calculations, and HMRC submissions, then compare that figure against a software subscription to see whether automating pays for itself.
• Prioritise key features when comparing payroll tools, including automatic tax calculations, pension auto-enrolment, cloud access, and scalability, and use free trials to check that the software suits your business before committing.
• Switch from free tools like HMRC's Basic PAYE Tools to paid payroll software once your team grows beyond 10 employees or you need accounting integration and automation, as the time saved typically outweighs the monthly cost within the first few pay runs.

What is payroll software?

Payroll software automates paying employees, calculating deductions, and reporting to HMRC. It handles the calculations, paperwork, and submissions that would otherwise take hours of manual work, simplifying processes like the regular submission of payment information to HMRC.

At its simplest, payroll software calculates gross pay, deducts tax and National Insurance, and produces payslips. More comprehensive tools also manage:

• workplace pensions and auto-enrolment
• statutory payments like sick pay, maternity pay, and paternity pay
• holiday tracking and leave requests
• Real Time Information (RTI) submissions to HMRC

Most modern payroll software runs in the cloud, meaning you access it through a web browser rather than installing it on a computer. This makes it easier to run payroll from anywhere and share access with your accountant.

What payroll software does for your business

Some small businesses still manage payroll manually or outsource it entirely. Both approaches work, but they come with trade-offs in time, cost, and control. Payroll software offers an alternative that many small businesses find more practical.

This guide helps you decide whether payroll software can save your business money by examining what it costs, what it does, and how it compares to the alternatives.

HMRC-recognised software and compliance requirements

HMRC-recognised payroll software meets the technical standards required to submit payroll reports directly to HMRC. Using recognised software is the simplest way to stay compliant with UK payroll regulations.

HMRC recognition means the software:

• submits Real Time Information (RTI) reports electronically
• meets HMRC's security and data standards
• provides updates when tax rates or rules change

Recognised payroll software automates several compliance tasks that would otherwise require manual attention:

• RTI submissions: Every time you pay employees, you must send a Full Payment Submission (FPS) to HMRC (though if no payments are made, you must submit an EPS instead). Recognised software does this automatically.
• Tax code updates: HMRC sends tax code changes electronically, and the software applies them without manual input.
• Year-end reporting: The software generates P60s for employees and submits final reports to HMRC.

Accurate payroll protects your business from costly penalties. Non-compliance penalties include:

• late RTI submissions: Penalties start at £100 per month for small employers.
• incorrect tax calculations: You may owe back-payments plus interest.
• missing pension duties: The Pensions Regulator can fine employers up to £10,000 per day, as demonstrated when Swindon Town Football Company received fines totalling £22,900 for non-compliance, as reported by ACCA.

HMRC-recognised software eliminates the most common compliance failures, though you should still review your submissions.

Free vs paid payroll software

Free payroll software is available, and understanding its features helps you choose the right option for your growing business.

Basic PAYE Tools: HMRC's free option

Basic PAYE Tools is free payroll software from HMRC for businesses with fewer than 10 employees. It handles core payroll tasks including:

• calculating PAYE tax and National Insurance
• submitting RTI reports to HMRC
• producing payslips and P60s
• recording statutory payments

Basic PAYE Tools involves more manual data entry than paid alternatives. You enter data for each pay run manually, and accounting software integration and task automation are available in paid versions.

When paid payroll software becomes essential

Paid payroll software makes sense when your business needs automation, integration, or support that free tools don't provide. Consider upgrading when you:

• have more than 10 employees
• want automatic tax calculations without manual data entry
• need integration with your accounting software
• require pension auto-enrolment management
• value time savings over subscription costs

For most small businesses, the time saved with paid software outweighs the monthly cost within the first few pay runs.

What to consider for payroll

Payroll involves far more than paying wages on time. Small businesses need to manage pay and compensation tasks including:

• recording payment dates and amounts for every employee
• handling salaries, hourly rates, bonuses, and commissions
• processing expense reimbursements

Beyond pay calculations, tax and compliance tasks require ongoing attention:

• calculating and submitting PAYE to HMRC
• meeting government reporting deadlines
• managing workplace pensions

Accurate employee records are essential for compliance and audit readiness:

• tracking holiday entitlement and carry-over
• recording sick days and absences
• processing statutory maternity and paternity pay
• logging start dates and termination dates

Benefits administration adds another layer of complexity to payroll:

• accounting for taxable perks and benefits

Mandatory payrolling of benefits in kind has been delayed until April 2027.

Each of these tasks requires accuracy and timeliness. Handling them correctly helps you avoid penalties and keeps employees satisfied.

Choose payroll accounting software wisely

The right payroll software depends on your business needs. When comparing options, prioritise these features:

• Automatic tax calculations: The software should automatically calculate PAYE, National Insurance, and student loan amounts to deduct, with rates updated each tax year. Assigning payroll numbers can also help you manage your employees more easily.
• Workplace pension compliance: Look for software that automatically calculates what employers and employees contribute to pensions under auto-enrolment rules.
• RTI submissions: Choose software that submits Full Payment Submissions (FPS) directly to HMRC each pay run.
• Audit trail: Every payment, adjustment, and leave record should be logged and traceable.
• Cloud access:Browser-based software lets you run payroll from any device without installing updates.
• User permissions: Set different access levels so employees can view payslips while sensitive data stays protected.
• Leave management: Allow staff to request holiday through the system and approve it with a click.
• Scalability: Check the software handles your current team size and can grow with your business.
• HMRC relief claims: Some software helps you claim Small Employers' Relief and other allowances automatically.

Before committing, test the software yourself. Most providers offer free trials. Check that the interface is intuitive and easy to learn, and read recent reviews from businesses similar to yours.

What is payroll software worth to your business?

Payroll software is worth the cost when the time it saves and the errors it prevents outweigh the subscription fee. For most small businesses with employees, the answer is yes.

Some accounting systems include payroll as standard. Others charge extra. Either way, the real cost comes from the hours you spend on manual payroll tasks and ensuring compliance accuracy.

Four questions help you decide whether payroll software makes financial sense for your business.

What will the software cost you?

Research what payroll software actually costs in the UK market. Prices vary based on features and number of employees, so compare these typical pricing factors:

• monthly subscription fees: Most cloud-based payroll software charges per month, often with tiers based on employee count.
• per-employee costs: Some providers charge a base fee plus an amount per employee.
• user limits: Check whether adding your accountant or bookkeeper costs extra.

What will manual payroll cost you?

Calculate how much time you currently spend on payroll each month. Include time spent on:

• entering employee hours and calculating pay
• working out tax and National Insurance deductions
• submitting reports to HMRC
• managing pension contributions
• answering employee payroll queries

Multiply these hours by your hourly rate or the salary cost of whoever handles payroll. This gives you the true cost of manual payroll processing.

What could mistakes cost you?

Consider the financial impact of payroll errors. Common mistakes include:

• late HMRC submissions leading to penalty charges
• incorrect tax calculations requiring back-payments
• missed pension contributions attracting regulator fines
• employee dissatisfaction from pay errors

These costs often exceed the price of payroll software many times over.

How much will you save with automation?

Compare the total cost of manual payroll and potential errors against the software subscription fee. Most small businesses find that payroll software pays for itself within a few months through:

• reduced time spent on payroll tasks
• fewer errors and compliance issues
• better use of staff time on revenue-generating activities

FAQs on payroll software

Common questions about choosing and using payroll software for your small business.

Do I need payroll software if I only have a few employees?

Payroll software helps businesses of all sizes. Even with just one or two employees, you must comply with HMRC reporting requirements, calculate tax correctly, and manage pension auto-enrolment. Software automates these tasks and reduces the risk of costly errors.

Can I switch payroll software mid-year?

Yes, you can switch payroll software at any time during the tax year. Most providers help you transfer your data from your current system. Choose a time between pay runs to make the transition smoother.

Does payroll software integrate with my accounting software?

Most modern payroll software integrates with popular accounting platforms. This connection automatically transfers payroll data to your accounts, saving time and reducing duplicate data entry. Check compatibility before choosing your software.

How secure is cloud-based payroll software?

Cloud-based payroll software from recognised providers uses bank-level encryption and security measures. Look for software that meets HMRC's security standards and stores data in secure UK or EU data centres.

What happens if I make a mistake using payroll software?

Payroll software reduces errors but doesn't eliminate them entirely. If you spot a mistake, you can usually correct it in the next pay run. For HMRC submissions, the software lets you send corrected reports. Many providers offer support to help you fix issues quickly.
