Fix problems with running payroll

Printable version

1. Your PAYE bill is not what you expected

Every month you have to pay HM Revenue and Customs (HMRC) what you owe as part of running payroll for your employees.

There are things you should check if your PAYE bill is not what you expected when you view your

This guide is also available in Welsh (Cymraeg).

What to check

Make sure you sent your Full Payment Submission (FPS) or Employer Payment Summary (EPS) in time for the account to update.

You should also check that you:

  • used the date you paid your employees on your FPS report, not the date you sent it
  • reported other details in your FPS correctly, for example pay and deductions
  • reported your EPS correctly, for example to reclaim any statutory pay
  • previously paid HMRC the right amount - you may have paid too much or too little if your reports were incorrect

Employees starting and leaving

Check that you correctly reported any employees starting or employees leaving.

You may get an incorrect bill and duplicate payroll records if you made a mistake. Both are usually corrected automatically - contact HMRC if your PAYE bill is still wrong by the 12th of the next tax month.

Correcting errors

If you find a mistake, follow the guidance to:

You can also correct mistakes if you paid your employee the wrong amount or made incorrect deductions.

2. You made a mistake in your FPS or EPS

Your PAYE bill might be wrong if you made a mistake in your Full Payment Submission (FPS) or Employer Payment Summary (EPS). You might have to correct:

You鈥檒l only be charged a penalty for a mistake if you did not take reasonable care or did it deliberately.

If you鈥檝e reported the wrong pay or deductions

To correct a mistake made in the current tax year, update the year-to-date figures in your next regular FPS.

If you鈥檙e correcting an聽FPS聽for a previous payment and the 鈥榩ayment after leaving (PAL)鈥� box is ticked do not enter the same amounts in the 鈥榩ay in period鈥� and 鈥榩ay in year-to-date鈥� fields. Doing this will create a duplicate record for your employee.

The rules are different if you find a mistake in your final FPS of the year.

If the mistake was in the tax years between 6 April 2020 and 5 April 2025

Submit another FPS with the correct year to date figures.

If the mistake was in the tax year between 6 April 2019 and 5 April 2020

You can either submit:

  • a further FPS with the correct year to date figures
  • an Earlier Year Update (EYU) showing the difference between what you originally reported and the correct figure

You can only use an EYU for tax years when you were reporting online in real time.

If your payroll software cannot send an EYU, you can use HMRC鈥檚 Basic PAYE Tools.

Correct a pension death benefit or flexibility payment

If you鈥檙e a pension administrator who needs to correct a flexibility payment or death benefit payment:

  • select the 鈥榩ension flexibility payment鈥� or 鈥榩ension death benefit payment鈥� indicator
  • update the 鈥榩ensions drawdown taxable payment鈥� or 鈥檖ensions drawdown non-taxable payment鈥� fields (or both) with the difference between what you originally reported and the correct figures

If your payroll software cannot do this, contact your software provider.

If your employee has stopped working for you

Include them in your next FPS and correct their year-to-date figures. Include their original 鈥楧ate of leaving鈥� and put the same or a later 鈥楶ayment date鈥� than the one shown on their final FPS.

Correct the payment date in your FPS

You should use the date you paid your employees in your FPS.

Send an additional FPS with the correct payment date if you鈥檝e sent one with the wrong payment date. Write 鈥楬 - correction to earlier submission鈥� in the 鈥楲ate reporting reason鈥� field.

If you鈥檙e correcting an聽FPS聽for a previous payment and the 鈥榩ayment after leaving (PAL)鈥� box is ticked, do not enter the same amounts in the 鈥榩ay in period鈥� and 鈥榩ay in year-to-date鈥� fields. Doing this will create a duplicate record for your employee.

You need to put 0.00 in the 鈥榩ay in period鈥� field. The year-to-date entry should stay the same for the previous聽FPS.

Send your corrected FPS by the 19th of the tax month after you sent your original FPS. HMRC will apply the correction to the right month.

If the wrong date was in different tax month, you must realign your payroll to the correct tax period.

Correct an employee鈥檚 start or leaving date

Update your payroll records with the correct date if you put the wrong start or leaving date for an employee in your FPS.

Do not report the amendment in your next FPS as this may create a duplicate record for the employee.

Correct your employee鈥檚 personal information

Correct your next FPS if you鈥檝e made a mistake with your employee鈥檚 personal details.

Do not report updates to more than one of your employee鈥檚 personal details (for example their name, date of birth or gender) in the same FPS. Your payroll records may be duplicated if you do, and your PAYE bill might be wrong.

If your employee鈥檚 details (for example their address or surname) change:

Correct FPS reports sent in advance

If you鈥檝e sent FPS reports in advance that need to be corrected (for example because an employee leaves), you should:

  • send another FPS for the tax month the correction relates to, making sure you fill in all relevant fields and revising the year-to-date figures if needed

  • correct any other FPS reports you sent in advance that are affected by the change

Correct an employee鈥檚 National Insurance category letter

How you do this depends on why the category letter changed, and in which tax year.

You鈥檝e used the wrong category letter in the current tax year

Report the mistake in your next FPS.

  1. Add the category letter you鈥檝e used incorrectly.

  2. Put 鈥�0鈥� in all National Insurance fields for this category letter except 鈥楨mployee鈥檚 NICs this payment鈥�, and enter the amount you have repaid or recovered here, for example put -拢300 if you鈥檙e repaying an employee鈥檚 overpayment of 拢300.

  3. Add the correct category letter, and enter the correct year-to-date National Insurance for this category letter.

  4. Put 鈥�0鈥� in all National Insurance fields for the incorrect category letter for the rest of the tax year - you do not need to do this if the category should never have been used.

Some software allows you to correct this by adjusting net pay. You鈥檒l still need to keep a record of the change.

Your employee鈥檚 category letter changed during the tax year

In your next FPS:

  1. Continue to report year-to-date information for the old category.

  2. Put 鈥�0鈥� in all 鈥業n this pay period鈥� fields for this category, and use the 鈥楨mployee鈥檚 NICs this payment鈥� field to adjust any underpayment or overpayment of National Insurance.

  3. Add the correct category letter, and enter the correct year-to-date National Insurance for this category letter.

You鈥檝e used the wrong category letter in the tax years between 6 April 2021 and 5 April 2025

Send an additional FPS with the correct category letter and correct year-to-date National Insurance for this category letter.

If the mistake was in the 2020 to 2021 tax year or earlier

Send an EYU with:

  • negative amounts in all the National Insurance year-to-date fields in the incorrect category letter, to reduce the employee鈥檚 National Insurance to zero
  • the correct category letter and correct year-to-date National Insurance

If you鈥檙e correcting a mistake in the 2019 to 2020 or 2020 to 2021 tax years, you may be able to send an FPS instead - use your payroll software to check. Send it with the correct category letter and correct year-to-date National Insurance.

If the mistake caused an overpayment or underpayment

You must correct your employee鈥檚 National Insurance deductions if they paid too little or too much because they were on the wrong category letter.

Correct an employee workplace postcode when claiming National Insurance relief in UK Freeport or Investment Zone special tax sites

If you鈥檝e submitted an FPS with an incorrect employee workplace postcode, use the correct workplace postcode from your next regular FPS.

Correct an EPS

To correct a mistake in the current tax year, send an EPS with the correct year-to-date figures.

For previous tax years, send an EPS with the correct year-to-date figures for the tax year where you made the mistake.

3. You paid HMRC the wrong amount

What you need to do to correct a payment depends on whether you paid too much or too little, and how the error occurred.

If you鈥檝e paid HMRC too little

If you underpaid because of a mistake in your Full Payment Submission (FPS) or Employer Payment Summary (EPS), correct it in your next regular report. HM Revenue and Customs (HMRC) will add the underpayment to your next PAYE bill.

If you underpaid because you entered the wrong amount when paying HMRC, pay the balance as soon as possible or you may have to pay interest or a penalty. Use your Accounts Office reference when paying.

If you鈥檝e paid HMRC too much

If you overpaid because of a mistake in your FPS or EPS, make the correction in your next regular report. HMRC will take the overpayment off your next PAYE bill.

If you overpaid because you entered the wrong amount when paying HMRC, or you made a duplicate payment, you can balance your account by paying less in your next PAYE bill.

You can also claim a refund if you鈥檝e overpaid.

4. You paid your employee the wrong amount or made incorrect deductions

You can correct a mistake with an employee鈥檚 pay or deductions by updating the year-to-date figures in your next regular Full Payment Submission (FPS).

You can also correct it by sending an additional FPS before your next regular FPS is due. You need to:

  • update the 鈥榯his pay period鈥� figures with the difference between what you originally reported and the correct figures
  • correct the year-to-date figures
  • put the same payment date as the original FPS
  • put the same pay frequency as the original FPS
  • put 鈥楬 - Correction to earlier submission鈥� in the 鈥楲ate reporting reason鈥� field

Correct a pension death benefit or flexibility payment

If you鈥檙e a pension administrator who needs to correct a flexibility payment or death benefit payment, you must:

  • select the 鈥榩ension flexibility payment鈥� or 鈥榩ension death benefit payment鈥� indicator
  • update the 鈥榩ensions drawdown taxable payment鈥� or 鈥檖ensions drawdown non-taxable payment鈥� fields (or both) with the difference between what you originally reported and the correct figures

If you underpaid your employee

Pay your employee the amount you underpaid them. On or before the day of this payment, send an additional FPS with:

  • the difference between what you originally reported and the correct amount in the 鈥業n this pay period鈥� field
  • updated year-to-date figures
  • 鈥楬 - Correction to earlier submission鈥� in the 鈥楲ate reporting reason鈥� field

Correct an employee鈥檚 National Insurance deductions

What you need to do depends on when you made the mistake.

If the mistake was in this tax year

Repay or deduct the balance from your employee. Update the year-to-date figures to the corrected amount in your next regular FPS or send an additional FPS.

If you deducted too little, you cannot recover more than the employee鈥檚 National Insurance contribution due that month.

Example:

You deducted 拢100 too little in January. In February, your software calculates an 拢80 National Insurance deduction, which means you can recover up to 拢80 towards the underpayment that month (a 拢160 deduction in total).

Recover the remaining 拢20 in another month.

If the mistake was in the tax years between 6 April 2020 and 5 April 2025

Send an FPS with the amount you should have deducted.

You鈥檒l need to write to HMRC if both the following apply:

  • the difference is negative because you deducted or reported too much National Insurance
  • you still owe your employee a refund, for example because they鈥檝e left your employment

In the letter you鈥檒l need to include:

  • the reference 鈥極verpaid NI contributions鈥�
  • your employee鈥檚 name, date of birth and National Insurance number
  • why you overpaid National Insurance contributions
  • which tax years you overpaid in
  • how much National Insurance you overpaid
  • why you are unable to make the payment to the employee

For a claim for one employee, send the letter to:

HM Revenue and Customs
National Insurance Contributions and Employer Office
BX9 1AN

For a claim for more than one employee, send the letter to:

HM Revenue and Customs
National Insurance Contributions and Employer Office
BX9 1BX

If the mistake was in the tax year between 6 April 2019 and 5 April 2020

Send an FPS with the correct year-to-date National Insurance if:

  • your payroll software will let you submit an FPS
  • you can pay any National Insurance refunds you owe

If you cannot use an FPS, send an Earlier Year Update (EYU) with the difference between:

  • the amount of National Insurance you originally deducted
  • the correct amount you should have deducted

If the difference is negative (because you deducted or reported too much National Insurance), you also need to set the 鈥�NIC refund indicator鈥� to:

  • 鈥榊es鈥� if you鈥檝e refunded your employee or no refund was due
  • 鈥楴o鈥� if you still owe your employee a refund (for example because they鈥檝e left your employment)

If there鈥檚 an underpayment

If you deducted too little National Insurance, pay HMRC the underpayment straight away. You can then recover the amount from your employee by making deductions from their pay.

You cannot recover more than the amount of National Insurance the employee owes in a month (so the employee pays no more than double their normal contribution). Carry over the difference to later months - you can only make deductions in the tax year when you made the mistake and the year after.

Correct an employee鈥檚 student loan repayments

What you need to do depends on when you made the mistake.

If the mistake was in this tax year

Repay or deduct the balance from your employee. Update the year-to-date figures to the corrected amount in your next regular FPS or send an additional FPS.

If you deducted too little, you cannot recover more than the student loan repayment due that month.

Example:

You deducted 拢50 too little in June. In July, your software calculates a 拢30 student loan deduction, which means you can recover up to 拢30 towards the underpayment that month (a 拢60 deduction in total).

Recover the remaining 拢20 in another month.

If the mistake was in previous tax years

You do not need to take any action if either of the following apply:

  • you鈥檝e deducted too little
  • you鈥檝e already submitted your final FPS for that year

Your employee should contact the Student Loans Company to find out how it affects them.

If you have deducted too much, and you have not sent your final FPS for that year, you can repay your employee. Send an FPS with the correct 鈥榮tudent loan repayment year to date鈥� figure as of 5 April for the previous tax year.
