New Tax Year, Less Payroll Stress: How Accounting Firms Can Save Time in 2026

April is a challenging time for accounting practices. Updating systems, recalculating taxes, and ensuring compliance for hundreds of employees. One mistake will trigger HMRC fines, disrupt the cash flow for your clients, and cause hassle for employees.

We noticed many accounting practices struggle to adjust to new PAYE thresholds and tax codes. Manual updates take time and will overwhelm your staff, leading to delays in payslips and reporting.

All this hassle can be avoided by adopting a structured payroll process and using payroll outsourcing support. Practices that have adopted this route and managed to bring down their payroll preparation time considerably, while improving their accuracy and client satisfaction.

This shows that saving time is possible even in the busiest payroll season, only if you approach it strategically.

In this guide, we’ll cover:

• The important updates for payroll in 2026
• Common pain points for UK accounting practices
• Time-saving strategies and automation
• How outsourcing with Corient can streamline payroll operations

Why the New Tax Year Changes Payroll

Every April, HMRC conducts changes in rates, and April 2026 is no different. These changes are in:

• Income Tax allowances and thresholds
• National Insurance rates and thresholds
• Statutory payment rates (SSP, SMP, SPP, SAP)
• Pension contributions and auto-enrolment rules

Even a small error in calculations or non-compliance will trigger HMRC penalties (ranging from 1 to 4% depending on the number of defaults in a tax year) or complaints from your clients. For firms managing multiple clients, manually updating each payroll is inefficient and risky.

Common Payroll Challenges at the Start of a New Tax Year

The new tax year in 2026 may look routine, but it often comes with multiple updates that, if missed, could lead to errors, delays, and compliance risks. Let’s break down these challenges in a practical, real-world way so you can manage them better.

Updated Tax Codes

On every new tax year, HMRC updates employee tax codes, and even a slight change can affect take-home pay.

This becomes a challenge when:

• Multiple clients are involved, which means hundreds of employees to update
• Mid-year changes can create confusion
• Incorrect codes lead to over- or under-taxation

What can go wrong:

• Employees receive incorrect payslips
• Client queries increase
• HMRC corrections become necessary

The best approach would be to:

• Cross-check all tax codes against HMRC notices before the first payroll run
• Use the best payroll software that auto-updates tax codes

Changes in National Insurance Threshold

National Insurance (NI) thresholds and rates are updated regularly and implemented in the new tax year that begins, and these changes must be applied accurately.

It can get confusing due to:

• Different thresholds for different employee categories
• Changes affect both employer and employee contributions
• Even minor miscalculations can accumulate over time

The impact of missing it will be:

• Incorrect payroll costs for clients
• Compliance risks with HMRC
• Time spent recalculating and correcting errors

The best approach will be to:

• Update payroll systems before the first pay cycle
• Verify calculations for different salary bands

Pension Adjustments

Auto-enrolment pension rules require careful attention, especially when thresholds or contribution percentages change.

It creates problems when:

• Employees are moved in/out of eligibility thresholds
• Contribution percentages needing updates
• Coordination is required between payroll and pension providers

It will lead to:

• Non-compliance with The Pensions Regulator
• Missed contributions or incorrect deductions
• Employee dissatisfaction

The ideal approach would be to:

• Review all employee eligibility at the start of the tax year
• Reconcile payroll data with pension provider reports

Statutory Payments

Statutory payments like:

• Statutory Sick Pay (SSP)
• Statutory Maternity Pay (SMP)
• Statutory Paternity Pay (SPP)

are updated each year and must be recalculated correctly.

Why this is challenging:

• Eligibility rules vary
• Calculation periods can be complex
• Errors are not always immediately visible

Impact of these challenges will be:

• Underpayment or overpayment
• Reprocessing payroll
• Increased client queries

The best approach will be to:

• Use payroll software with built-in statutory calculations
• Train staff on updated rules each year

Data Discrepancies

Errors in data are one of the most common and neglected challenges.

Typical issues under it include:

• Missing or late timesheets
• Incomplete employee data
• Outdated payroll records
• Incorrect working hours or rates

Why these matters:

• Without data accuracy, achieving payroll accuracy is impossible

Impact:

• Delayed payroll processing
• Rushed submissions
• Increased risk of errors

Best approach would be to:

• Standardise data collection from clients
• Set deadlines for updating timesheets and updates
• Use cloud systems for real-time data sharing

Before you start, your payroll conducts a thorough review of:

• Employee tax codes

Outsource Payroll Support

Many accounting practices in the UK are also placing their faith in payroll outsourcing services for expert support.
