Have you noticed your payroll software consistently prompting you to send something called an FPS to HMRC? It’s a term that might seem confusing at first, but understanding it is crucial for managing your payroll effectively. So, what is FPS, and why is it so important?
If you're running a small or medium-sized business, you might have come across this term more than once without fully understanding its significance. Don’t worry, you’re not alone, and we’re here to clear things up.
Payroll NI has been helping businesses across Northern Ireland and beyond manage the complexities of payroll, including FPS. We’ll break down everything you need to know about FPS in a way you’ll understand.
FPS stands for Full Payment Submission. It’s a report you send to HMRC (Her Majesty’s Revenue and Customs) every time you pay your employees. This submission is a vital part of the Real Time Information (RTI) system that the UK government uses to track employees’ pay, tax, and National Insurance contributions in real-time, rather than relying on end-of-year reporting.
For businesses, this means each time you run payroll, you also need to send an FPS to HMRC so that they’re kept up to date with the amount you’ve paid your staff, as well as the tax and National Insurance contributions that have been deducted.
You might be wondering why it’s necessary to submit payroll information to HMRC every time you pay your employees. The short answer is compliance. Without sending an FPS, HMRC wouldn’t know how much tax and National Insurance has been paid, and this could lead to issues for both your business and your employees.
Here's why the FPS is so crucial:
The FPS helps HMRC ensure that your employees are paying the correct amount of tax and National Insurance based on their earnings. It prevents underpayment or overpayment of taxes, which can lead to penalties or even refunds.
Failure to submit an FPS on time can result in fines from HMRC. If you miss a deadline or provide incorrect information, you could face additional charges. Keeping your FPS submissions accurate and timely helps you avoid unnecessary penalties.
HMRC uses the information from your FPS to calculate benefits like Universal Credit or tax credits for employees. Late or incorrect submissions could delay your employees receiving these benefits, potentially causing them financial stress.
Submitting your FPS on time shows that your business is compliant with UK payroll regulations. It’s an essential part of maintaining good standing with HMRC, especially if your company is ever audited.

The FPS must be sent on or before the day you pay your employees. This means that every time you run payroll, whether it’s weekly, biweekly, or monthly, you need to send this submission.
For example, if you’re paying your staff on the 25th of the month, you need to send the FPS on the 25th (or earlier). Sending it late could result in a fine, even if it’s just by a day or two.
An FPS includes all the key payroll information for each employee. It contains:
Names, National Insurance numbers, and tax codes.
Gross pay, tax deducted, and National Insurance contributions.
Any deductions for pensions, student loans, or other items.
Whether the employee has left or joined your business.
Payroll NI ensures that all this information is submitted accurately and on time, so you can focus on running your business rather than worrying about compliance.
If you’re using payroll software, it will typically prompt you to submit an FPS at the appropriate time. Most modern payroll software integrates directly with HMRC’s systems which makes it easy to file your FPS online with just a few clicks.
Here’s a quick overview of the process:
Calculate your employees' pay, including any overtime, bonuses, or deductions for that pay period.
Your payroll software will generate an FPS report. Review this carefully to make sure all the information is correct.
Once you’re satisfied that everything is correct, submit the FPS to HMRC through your payroll software. You should receive a confirmation that it has been submitted successfully.
With Payroll NI’s fully managed payroll services, we take care of this entire process for you. You don’t have to worry about software glitches or missed submissions because our team ensures everything runs smoothly and on time.
Mistakes happen, but when it comes to payroll, accuracy is crucial. If you accidentally submit an incorrect FPS, it’s important to correct it as soon as possible to avoid any penalties or issues with HMRC.
Here’s what you can do:
If the mistake is for the current pay period, you can usually correct it in your next FPS submission. Most payroll software will allow you to make adjustments for errors like underpayments or overpayments.
If you discover the mistake after submitting your FPS, you may need to send an additional FPS to correct the error. This is known as an "FPS adjustment."
Payroll NI makes sure your submissions are accurate, but in case any errors do occur, our team can promptly resolve them and ensure that your business stays compliant.

Submitting Full Payment Submission (FPS) reports is crucial for keeping your business compliant with HMRC regulations. However, it’s easy to make mistakes that can lead to penalties, stress, and extra work. Payroll NI has seen many businesses face unnecessary challenges simply because of avoidable errors in their FPS submissions.
Here are some of the most common mistakes we’ve encountered and how you can avoid them:
Mistakes such as wrong names, National Insurance numbers, or incorrect addresses can cause delays and rejections by HMRC. These might seem like small errors, but HMRC’s systems require precise information to match employees’ details. It's essential to double-check this data before submitting FPS.
Solution
Make sure employee records are always up-to-date, and run a quick verification before each payroll cycle.
Submitting FPS late is one of the easiest ways to face a fine. You must submit FPS every time you pay your employees, and it should be done on or before payday. Some businesses fail to submit on time due to a misunderstanding of the deadline, system errors, or simply overlooking it.
Solution
Use reminders, or better yet, let Payroll NI handle it for you to ensure your FPS is always submitted on time.
Sometimes, employers forget to include all employees in their FPS, especially if they’ve recently hired someone or had temporary workers. Also, submitting the wrong pay figures, whether underpaying or overpaying, can cause major issues for both you and your employees.
Solution
Regularly audit your payroll records to ensure all employees are included, and their pay is accurate.
Using incorrect tax codes, especially after a change in an employee’s tax status, can cause errors in FPS submissions. For example, if an employee has switched jobs or had a tax code change, failing to update this information will lead to discrepancies.
Solution
Keep an eye on any tax code changes and make sure they are reflected in your payroll system immediately.
When employees receive statutory payments like Sick Pay (SSP) or Maternity Pay (SMP), employers must report these in the FPS. Some businesses overlook these, leading to errors in both payroll records and HMRC submissions.
Solution
Ensure that any statutory payments are accurately recorded in your payroll software before submission.
If there are months where no employees are paid (e.g., due to seasonal business), some employers think they don’t need to submit FPS. However, you still need to submit an FPS stating that no payments were made.
Solution
Even if you’re not paying employees during a payroll cycle, submit a "nil" FPS to avoid penalties.
