Interest on late payment of PAYE and CIS for employers

Find information on how interest is charged on PAYE and Construction Industry Scheme (CIS) payments made late if you're an employer.

When interest is charged

HMRC charges interest on any late PAYE and Construction Industry Scheme (CIS) payments. This is to compensate the Exchequer for late payment and to provide a measure of fairness to those taxpayers who pay what is due on time.

HMRC will charge interest on all unpaid:

  • PAYE tax, Class 1 National Insurance contributions (NICs) and student loan deductions including specified charges
  • Construction Industry Scheme (CIS) charges
  • in-year late filing penalties
  • in-year late payment penalties
  • any amount payable for month 12 at the end of the tax year which is still outstanding after 19 April
  • underpayments that arise because of an adjustment reported on an Earlier Year Update (EYU) or Full Payment Submission (FPS)
  • annual payments such as Class 1A and Class 1B National Insurance contributions which remain unpaid after the due date

How much you pay

HMRC will charge interest daily, from the date a payment is due and payable to the date it is paid in full. Current interest rates are set out at HMRC interest rates.

Charge Interest is charged from
PAYE tax, Class 1 National Insurance contributions, student loan deductions and CIS payments Day 19 of relevant month or quarter for all cheque payments, day 22 of relevant month or quarter for all electronic payments
EYU or FPS 19 April for all cheque payments, 22 April for all electronic payments
Underpayments at the end of the tax year 19 April for all cheque payments, 22 April for all electronic payments
Penalties Relevant due date of the penalty charge
Class 1A National Insurance contribution charges 19 July for all cheque payments, 22 July for all electronic payments
Class 1B National Insurance contribution charges 19 October for all cheque payments, 22 October for all electronic payments

Accrued interest is only a guide to what may be due and is calculated on the full charge due, even if this has been cleared in part. Interest is charged when the amount due is settled. Interest is shown as accruing from day 19 of each month, regardless of how the employer pays.

Employers who pay electronically will see an accrued interest entry between day 19 and day 22 a month. Once the electronic payment is received, the calculation will correctly use day 22 as the due date, and any interest charge generated between day 19 and day 22 will be cancelled.

HMRC will apply repayment interest where you make a payment and the charge is then reduced resulting in an overpayment which is either reallocated to a later charge or repaid.

Find out what is due

Your online PAYE account will be updated regularly to show the amount of any charged or repayment interest that is building up or due as follows:

  • late payment interest (due or paid) will appear at the bottom of the month in which the interest charge was made
  • accruing late payment interest will appear at the bottom of the current tax month — accrued interest is only a guide to what may be due
  • repayment interest to be paid will appear at the bottom of the current tax month
  • repayment interest already paid will appear at the bottom of the tax month in which it was repaid
  • for more detail, you can select a link from these items to a breakdown showing more detail about it

You cannot appeal against an interest charge. If you do not agree with the amount charged, write to the issuing office explaining why.
