Payroll Clean Up

May is a key month for employers because the payroll year end process does not finish when the tax year closes on 5 April. For the 2025 to 2026 tax year, which ran from 6 April 2025 to 5 April 2026, employers still need to check that payroll records are complete and that employees receive the right year end documents.
The most immediate deadline is the P60 deadline on 31 May 2026. Employers must give a P60 to employees who were on the payroll on 5 April 2026. The P60 summarises pay, Income Tax, National Insurance and other key payroll details for the tax year.
This is not just an employee document. It is also a useful checkpoint for employers. If payroll data is wrong, the error can flow into employee tax records, mortgage applications, benefit claims, Self Assessment Tax Returns, P11D reporting and director records.
A good payroll year end clean up helps small businesses move from year end administration into cleaner ongoing Payroll, stronger Bookkeeping, better Employee Benefits records and more reliable Management Reporting.
Payroll Clean Up
A payroll clean up is the process of checking that payroll information for the closed tax year is complete, accurate and ready for the next reporting step.
The tax year ended on 5 April 2026. By May, the final Full Payment Submission for the year should already have been sent to HMRC on or before the final payday of the tax year. If the final payroll submission was not marked correctly, or if payroll information was incomplete, employers may need to check whether any further correction is required.
The P60 is the most visible part of the May process. Employers must give a P60 to every employee who was working for them on 5 April 2026. The deadline is 31 May 2026. The P60 can be provided on paper or electronically, depending on the payroll process used.
The P60 should reflect the employee’s total pay and deductions for the tax year. This includes taxable pay, Income Tax deducted, National Insurance contributions and other payroll information produced through the employer’s Payroll software.
For small employers, this is where errors often become visible. A payroll record may have an incorrect address, wrong tax code, missing starter details, incorrect leaving date, director pay issue, pension contribution mismatch or duplicated employee record. These may seem like admin details, but they can create problems later.
May is also a good month to check whether any benefits or expenses need further attention. If the business provided taxable benefits during the 2025 to 2026 tax year, such as company cars, private medical insurance, fuel benefits, beneficial loans or certain director benefits, the next deadline may be the P11D process. Expenses and benefits are normally reported by 6 July 2026, with electronic payment of Class 1A National Insurance due by 22 July 2026Â where applicable.
This makes May a useful bridge between payroll year end and Employee Benefits reporting. If benefit records are left until late June or early July, it becomes harder to check values properly. That increases the risk of rushed calculations, employee queries and late adjustments.
The same applies to Workplace Pensions. Payroll records should agree with pension submissions. Contributions should be checked against employee records, pensionable pay and provider submissions. This is especially important where employees joined, left, changed hours or moved between pay categories during the year.
Good Bookkeeping also matters. Payroll journals, PAYE liabilities, pension payments, staff costs and director payroll entries should agree with the accounting records. If the bookkeeping does not match the payroll reports, year end accounts and Corporation Tax Returns may be harder to prepare later.
The purpose of the clean up is not only compliance. It is to create a reliable payroll base for the 2026 to 2027 tax year, which started on 6 April 2026. Clean data makes monthly Payroll smoother, helps avoid employee queries and gives business owners a better view of staff costs.
How it impacts you
For employees, the P60 is an important document. It shows pay and tax information for the year and may be needed for mortgage applications, tax checks, benefit claims, student loan reviews or personal financial records. If it is late or incorrect, employees may need to ask questions at a busy time.
For employers, the P60 deadline is also a sign that the payroll year end process needs to be under control. Missing records, incorrect tax codes, wrong starter details or unresolved pay adjustments can create avoidable problems.
For directors of small limited companies, payroll year end can be especially important. Many directors take a low salary, dividends and sometimes benefits. If director payroll has not been processed correctly, the issue can affect personal tax, company records, dividend planning and future Self Assessment Tax Returns.
For contractors operating through limited companies, the impact depends on how the company uses payroll. A simple director only payroll may still need accurate P60 records, PAYE records and employer submissions. If there are additional employees, the process becomes more important.
For small businesses with staff, payroll clean ups can also highlight wider issues. Staff costs may have changed. Pension contributions may have increased. Benefits may have been added. Overtime or bonuses may have become more regular. These details affect cash flow, pricing and Management Reporting.
If payroll data is poor, the business owner may not know the true cost of employing people. Payroll is not only a compliance task. It is a major business cost and should feed into financial planning.
This is where payroll systems and Accounting Software need to work properly together. If Payroll reports, pension records, PAYE payments and Bookkeeping entries do not agree, the business may have unreliable financial information.
What you can do
Start with the P60 deadline. Check that every employee who was on the payroll on 5 April 2026Â has received their P60 by 31 May 2026. Make sure the P60 details are consistent with the payroll records submitted to HMRC.
Review employee records. Check names, addresses, National Insurance numbers, tax codes, starter dates, leaving dates and payroll IDs. Small data errors can create larger issues later, especially where employees need the information for personal tax or financial checks.
Check the final payroll submission for the year. Confirm that the final payroll information for the 2025 to 2026 tax year was submitted correctly and that any correction needed has been reviewed.
Reconcile PAYE and National Insurance balances. Compare the payroll reports to HMRC liabilities and the payments made from the business bank account. Any difference should be investigated before it carries forward into the next year.
Check Workplace Pensions. Payroll data should agree to pension submissions and payments. This is especially important where employees joined, left, opted in, opted out or changed pay during the year.
Review Employee Benefits early. If the business provided taxable benefits during the 2025 to 2026 tax year, start preparing before the 6 July 2026Â deadline. Gather invoices, benefit values, company car details, medical insurance records, director benefits and any relevant expense information.
Check Bookkeeping entries. Payroll journals should match the payroll reports. PAYE, National Insurance, pension liabilities, net pay and staff costs should all be correctly recorded in the accounting system.
Use the clean up as a planning exercise. Staff costs are often one of the largest expenses in a business. A clean payroll record can support better Management Reporting, cash flow forecasting and pricing decisions.
Ledgr Accountants can help employers review Payroll records, prepare P60s, check Employee Benefits, reconcile Bookkeeping entries and improve payroll processes for the new tax year. The aim is to make payroll clear, organised and less stressful before small errors become bigger year end problems.
