This article summarises the main tax late filing and payment penalties. In addition, you should be aware there are penalties for providing incorrect information.
As a small business owner you will have to deal with a number of different departments within HMRC. Each department has different forms to complete with different deadlines and different penalties should either your submission or payment be late. The following is a quick guide as to what you need to be aware of when dealing with HMRC and which deadlines you should put in your diary.
Under HMRC's Real Time Information (RTI) system, late filing penalties apply on a monthly basis. However, no penalty will apply for the first month in each tax year that a return is filled late.
New employers will not be penalised if their first Full Payment Submission (FPS) is received within 30 days of making their first payment to an employee.
Filing penalty notices are issued quarterly in July, October, January and April, showing the amount of the filing penalty for each tax month identified in that quarter.
Penalties for late filing may be imposed as follows:
Number of employees |
Monthly penalty (£) |
1 to 9 |
100 |
10 to 49 |
200 |
50 to 249 |
300 |
250 or more |
400 |
If you feel that a penalty has been issued in error, make sure to appeal against the penalty in writing to HMRC. Details of how to appeal can be found on HMRC's website.
Interest is payable on every late payment throughout the year. For PAYE purposes, periods run from the 6th of the month to the 5th of the following month. If paying by cheque, payment must be made by the 19th, whereas electronic payments must clear in HMRC’s bank account by the 22nd. HMRC now accepts Faster Payments, meaning funds can clear on the same day or the next working day, depending on your bank.
HMRC charges daily interest on late PAYE payments at a rate of the Bank of England base rate plus 4%, effective from 6 April 2025. The latest interest rates can be found on the Gov.uk website at: https://www.gov.uk/government/publications/rates-and-allowances-hmrc-interest-rates-for-late-and-early-payments. Interest will be backdated at the end of the tax year once you have filed your Employer Annual Return.
Penalty charges may also be issued for missed PAYE payments...

If you operate in the construction industry you must file a return to report the deductions you have made from your subcontractors on a monthly basis. The period runs from the 6th of the month to the 5th of the following month and you have 14 days to make the return. For example, for the period from the 6th of May to the 5th of June you must file the return by the 19th of June.
The payment of the CIS deductions is made at the same time as your PAYE payments and have the same deadlines as described above.
You must make a return every month even when no deduction has been made: if no deductions have been made then you must file a nil return. The penalties for failing to file the monthly return are the same as the PAYE penalties described above.
CIS is paid at the same time as PAYE and follows the same payment pattern. The same penalty and interest regime applies as outlined above.
P11D forms are required if you provide benefits to employees. Some examples include a company car, fuel, private medical insurance, beneficial loans and accommodation. The P11D also give a breakdown of the expenses provided to each employee. The P11D(b) declares the Class 1A National Insurance payable by the employer.
Forms P11D should be filed by the 6th of July following the tax year. An initial penalty of up to £300 per return may be charged for late filing, with a maximum penalty of £60 per return per day being charged where the failure continues.
For the P11D(b) summary form, where the return is up to 12 months late, HMRC may charge a penalty of up to £100 per month (or part month) for each batch (or part batch) of 50 earners for whom Class 1A is payable. Returns over 12 months late may be subject to a penalty of an amount not exceeding the amount of unpaid Class 1A NICs outstanding at 19 July.
Class 1A NICs need to be paid to HMRC by the 22nd of July if paying electronically, or by the 19th of July if paying by cheque.
The same penalties and interest rates apply to Class 1A National Insurance as to that under PAYE.
VAT returns are typically submitted quarterly, though monthly and annual accounting schemes are available. Each return must be filed online within 37 days after the end of the accounting period. For example, for a quarter ending on 31 May, the submission deadline is 7 July.
Cheque Payments: Must reach HMRC by the due date of the VAT return, which is the same as the filing deadline (e.g., 7 July for the period ending 31 May).
Electronic Payments: Payments must clear into HMRC’s account by the same due date. HMRC accepts Faster Payments, allowing same-day or next-day transfers, depending on your bank's processing times.
Direct Debit Payments: If you have a Direct Debit arrangement, HMRC will collect the payment automatically, typically three working days after the due date.
From 1 January 2023, HMRC implemented a penalty points system for late VAT return submissions:
For detailed guidance, refer to HMRC's official page www.hmrc.gov.uk.
Effective from April 2025, the late payment penalty structure is as follows:
These updated rates were announced in the Spring Statement 2025 to encourage timely payments.
In addition to penalties, HMRC charges late payment interest from the first day a payment is overdue until it is paid in full. The interest rate is linked to the Bank of England base rate plus 2.5%.
Avoiding Penalties
To avoid penalties:
Timely Submissions and Payments: Ensure VAT returns and payments are submitted and cleared by the due dates.
Time to Pay Arrangements: If unable to pay on time, contact HMRC promptly to discuss a Time to Pay arrangement, which may prevent penalties if agreed upon within the specified periods.
Staying informed about these regulations and adhering to deadlines will help you avoid unnecessary penalties and interest charges.
