Important UK monthly payroll deadlines + dates for your 2025 calendars

Between preparing for the end of the UK tax year and generally planning out your time, it’s important not to miss key payroll dates. 

Forgetting important submission deadlines not only causes delays when running payroll but can also lead to fines or penalties from HMRC. This resource outlines all the essential annual payroll deadlines UK businesses need to observe.

Important annual payroll deadlines

Report your gender pay gap

March 31st

If you’re a public authority employer, you have until the 31st of March to submit your gender pay gap data for the previous tax year (or until the 5th of April if you’re a private employer). 
 You must gather your pay gap data by making a list of your relevant employees, and the gender of your employees.

For your gender pay gap calculations, you’ll need to gather relevant information on all your employees. PayFit provides all of this data for you.

New tax year begins

April 6th

Nope, it’s not a national holiday — it’s a major date for your payroll calendar (yay!). On the 6th of April, the new tax year begins, which means any new changes for the new tax year come into effect. So make sure you’re clear on what these mean for your organisation.

Submit final Employer Payment Summary (EPS)

April 19th 

By the 19th of April, you must submit your final Employer Payment Summary (EPS) for the previous tax year. You must submit the EPS to HMRC so they know there are no further submissions for the previous tax year. HMRC also requires a final submission of the tax year. This can be included either on your final FPS or EPS submission. 

P60 deadline (for employees to receive)

May 31st 

The 31st of May is the P60 deadline, or the day by which employees must receive their P60 if they were employed on the 5th of April of the current year.

Filing deadline for Expenses and Benefits Forms

July 6th 

By the 6th of July, you must file your Expense and Benefits Forms P11D(b) and P11D with HMRC. It’s also the last date to give P11D forms to relevant employees and the last date for the Employee Share Scheme Annual Return Form 42 to reach HMRC.

National Payroll Week

Sept 2nd to 6th 

There’s more to payroll than sending out payslips, and that’s what this week signifies. Although actually paying employees is imperative to how your organisation operates, payroll data can help drive important business decisions too. Payroll data unlocks useful information when it comes to identifying gender pay gaps, salary benchmarking to attract and retain great employees and understanding and reallocating resources. Dedicate this week to educating the wider business on the important part payroll plays.

PAYE and Class 1B National Insurance Contributions (NICs)

October 19th and 22nd 

If you submitted a PSA in July, this payment is for PAYE and NIC related to this. If paying by a nonelectronic method, such as a cheque, your PAYE and Class 1B NIC are due on the 19th of October, but if you’re paying electronically, this is due on the 22nd of October. 

As a reminder, here are some important payroll dates you’ll need to observe every month in order to have a smooth and compliant pay run. 

 

1st of every month 
 

Auto-enrolment staging date for a new group of companies.

5th of every month 
 

The month-end date for PAYE.

19th of every month 
 

The last day for submitting a real-time information employment payment summary (EPS).

22nd of every month 
 

The deadline date for payment of PAYE and NICs to HMRC’s Accounts Office by an electronic method is the 22nd of each month. The deadline for submitting by cheque is the 19th of every month.

Remember: Late or missed payments and submissions can result in an interest charge and a penalty fee. Avoid ever getting a late submission fee again with our automated payroll software — PayFit is HMRC-recognised and handles all RTI submissions (FPS & EPS) on your behalf.
