Employers must report pay and deductions correctly to HMRC, but errors can usually be fixed in your next FPS.

Employers need to use payroll software or other payroll services to record employees pay, deductions and national insurance contributions on or before each payday. They also need to consider other deductions such as pension contributions and student loan payments.

These payments are reported to HMRC in real time using a Full Payment Submission (FPS). This submission contains all relevant information for each employee.

If you have made a mistake with an employee’s pay or deductions this can usually be corrected by updating the year-to-date figures in your next regular FPS.

HMRC’s guidance also states that you can correct mistakes by submitting an additional FPS before your next regular FPS is due. You would need to:

• update the ‘this pay period’ 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 ‘H - Correction to earlier submission’ in the ‘Late reporting reason’ field

If you need to correct an employee’s National Insurance deductions, the action required will depend on whether the mistake occurred in this tax year or earlier tax years. There are also different actions that may be required to fix a mistake with an employee’s student loan repayments, again depending what tax year the mistake relates to.
