As April 2026 approaches, the familiar fear of the end of the pay year (PYE) will surely set in for some.

After all, looming reporting deadlines and mountains of administrative tasks can put pressure on even the most experienced payroll professionals.

What if this year could be different?

To help you move forward and approach this PYE with confidence, we’ve put together a list of common pitfalls you’ll want to avoid to keep your processes stress-free.

Disparate data

Accurate data is the foundation for a smooth payroll year-end.

However, keeping control of your data can be tricky, especially since employee information changes frequently.

People move, change bank accounts, tax codes are updated and salaries are adjusted.

If you keep these records in separate systems – or worse, in spreadsheets – the risk of something slipping through the cracks is enormous.

Now, incorrect data doesn’t just mean a headache for you; Data errors can lead to incorrect tax calculations, underpaid staff or even fines for non-compliance – the last thing you need when you’re already busy.

How to improve your payroll data

To format your data, you have two main options.

The first is to take a rigorous and manual approach – this means regularly auditing your payroll data to catch errors before they become problems.

A manual approach can be effective, but it is extremely time-consuming.

The smartest and time-saving route is Integration of payroll and HR softwarecreating a single source of truth.

Why software integration is a game changer

Software integration uses what is called an application programming interface (API).

Think of an API as a digital bridge that allows your systems to exchange information.

For example, with integration, if an employee updates their new address on your HR platform, the API instantly sends that information to your payroll software.

You don’t need to type it twice and you don’t have to worry about typos.

Excessive admin

During the end of the pay year, you may feel like you’re spending all your time on paperwork.

You should carry out a full review of all your payroll records and processes to ensure everything complies with HMRC requirements.

This requires in-depth analysis to ensure compliance.

On top of that, you have a mountain of other tasks:

• Meticulous record keeping for each employee
• Prepare and distribute P60s to all staff members on time
• Ensure all of your finalized payroll data is submitted correctly via Full Payment Submissions (FPS) and Employer Payment Summaries (EPS).

Relying on manual processes for all of this only adds unnecessary pressure and opens the door to costly mistakes.

How Automation Lightens Your Load

Relying on software significantly reduces the risk of errors and saves a lot of time.

Instead of tackling each task manually, software automation can take the weight off your shoulders.

Modern payroll software can handle the heavy lifting, from automatically generating and distributing P60s to ensuring your FPS and EPS submissions are correct and on time.

Tax changes

Tax codes are small but powerful numbers that decide how much tax to withhold from an employee’s paycheck. A concrete understanding is crucial for the end of the payroll year.

Although tax codes may seem simple at first glance, they can change regularly, creating significant headaches for you and your staff.

Why do tax codes change?

An employee’s tax code may be updated due to changes to their personal allowance, changes to company benefits or a direct update from HMRC based on their individual tax situation.

These updates occur as P9 notices from HMRC at any time of the year, requiring businesses to remain vigilant.

Especially, when the new tax year starts on April 6, you need to check out the P9X guide.

Missing this step is a common mistake that can throw your first paycheck of the year into chaos.

How to stay on top of tax changes

One method for staying on top of tax changes is to establish a process that accurately tracks and implements these changes.

Training staff to help them understand their tax codes can be effective and help them spot any discrepancies.

Of course, the easiest way to manage tax changes is to use good payroll software.

The right system can automate these adjustments for you: when HMRC issues new tax codes, the software can apply them automatically, significantly reducing the time you spend on manual updates and minimizing the risk of errors.
