Main Tax Late Filing and Payment Penalties

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.


Late Filing

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


10 to 49


50 to 249


250 or more


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.

Late Payment

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 should be made by the 19th whereas if paying electronically the payment has until the 22nd to clear in HMRC's bank account. HMRC do not accept Faster Payments so make sure to allow for at least 3 working days for the funds to clear.

HMRC charge daily interest on late payments of PAYE using HMRC late payment interest rates which can be found on the website at Interest will be backdated at the end of the tax year once you have filed your Employer Annual Return.

Late Filing

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 are 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.

Late Payment

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.

Late Filing

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.

Late Payment

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.


Late Filing and Late Payment

VAT returns are made quarterly in the majority of cases, but there are monthly and annual schemes.

You must file your VAT return online by the end of the month plus 7 calendar days of the period end. For example for a quarter ended in May, you must file your VAT return by the 7th of July.

If paying by cheque you must pay by the VAT return due date but if paying electronically you can also pay any VAT due by the 7th. Again, HMRC do not accept Faster Payments so you must ensure funds clear by then. Furthermore, if paying by direct debit HMRC will collect payment a further 3 working days after the 7th.

From January 2023 the rules changed regarding late VAT returns. Offenders receive penalty points. The level of fines are based on how many points you get. Each late return incurs penalty points. You’ll receive a £200 penalty when you hit the threshold.

HMRC explains with this example, stating: “A company submits their VAT Return quarterly. This means their penalty point threshold is 4. They already have 3 penalty points because they submitted 3 previous returns late. They submit their next return late and get a fourth penalty point. Because they’ve reached the penalty point threshold, they receive a £200 penalty.”

For the full details visit this page.

Late payment fines for VAT payments begin if they arrive 16 days or more overdue.

The penalties increase, the longer the payments are overdue. Between 16 and 30 days a rate of 2% is charged on the amount of VAT owed. Then it goes up to after 31 days or more with a 2% charge on what’s outstanding at day 30.

See a detailed table on HMRC’s website here.

Personal Tax - Self Assessment

Late Filing

The penalties for late Self Assessment returns are as follows:

  • Initial £100 penalty for late filing of the tax return, irrespective of the tax due or if you have paid tax on time.

  • If you haven't filed your return after 6 months a further penalty of 5% of the tax due or £300: whichever is greater.
  • After one year, another 5% or £300 charge, whichever is greater. In serious cases the penalty after 12 months can be up to 100% of the tax due.

The penalties are applicable even if no tax is due.

Late Payment

Interest is applied to any late payment of tax at the rates shown at If you don't pay the tax you owe for the previous tax year on time by 31st January the following penalties apply...

  • If not paid within 30 days a 5% surcharge of the tax due applies.
  • If the payment is six months late a further 5% penalty is payable.
  • If the tax goes unpaid for 12 months a further 5% surcharge is payable.
