Make a disclosure about misusing your till system

Use this form to tell HMRC that you've been using your till system to reduce your tax bill.

You cannot use this form if you want to report someone else for using till systems to reduce their tax bill.

If you know anyone who is using till systems to reduce their tax bill, known as electronic sales suppression (ESS), you can report tax fraud and avoidance to HMRC. When reporting this way, choose ‘Fraud related to VAT’ as the type of activity and quote ESS23 when you describe the activity.

HMRC is writing to businesses that are suspected of using till systems to reduce their tax bill.

What the form is for

You should use this form to tell HMRC about any tax you owe as a result of using till systems to reduce your tax bill. This is known as ‘making a disclosure’. You do not have to wait for HMRC to contact you.

If you have received a letter from HMRC about your till system, you can also use this form to tell us you do not have any undeclared sales.

By making this disclosure now, you could reduce the amount of penalties you receive. If you do not make your disclosure in time, HMRC may open an investigation into what your business owes.

HMRC will follow up with those who do not make a disclosure, which could lead to more severe penalties.

You can use this form if you’re:

  • an individual

What happens next

If we accept your disclosure, we will raise a charge and tell you how to pay it. If we do not accept your disclosure, we will write to you and explain what to do next.

If we find that the information you have provided is significantly incorrect, we will open an investigation.

The maximum penalty amount we can charge for an inaccuracy or failure to notify is 100% of the tax due. If your non-compliance involves offshore transfers outside the UK, you may be subject to higher penalties. There is more information on penalties in our factsheets:

HMRC charges daily interest on late tax payments. Paying any tax you owe sooner will reduce the amount of interest you have to pay.
