What penalties apply for till tampering or Electronic Sales Suppression (ESS)?

This is a freeview 'At a glance' guide to Electronic Sales Suppression (ESS) penalties.

Finance Act 2022 included legislation covering HMRC's new powers to tackle electronic sales suppression. It follows their Earlier consultation. The rules took effect from 24 February 2022.

Electronic Sales Suppression (ESS), also known as till fraud or till manipulation, is the practice of deliberately manipulating electronic sales records to hide the value of individual transactions. This practice artificially reduces the recorded turnover of the business evading tax while producing a credible audit trail.

The measures are aimed at developers, promoters, suppliers and users of ESS tools and make them liable for penalties.

An ESS tool is a physical device, software, computer code or other digital data, as well as any other thing which:

Penalties of up to £50,000 per tool (by way of a percentage, as an HMRC officer considers appropriate) can be charged to:

The amount charged will depend on how complex the tool is, whether the disclosure was prompted or unprompted, the quality of the disclosure and whether there are any special circumstances to take into account.

Penalties of up to £1,000 can be charged if:

Further daily penalties of up to £75 per day (up to a total of £50,000) can be charged where possession or access to the tool continues.

From 4 March 2024, interest is charged on the late payment/repayment of ESS penalties. Interest is charged/paid under sections 101 and 102 of FA 2009. 

Voluntary disclosure

There was a window of opportunity between 6 January 2023 and 9 April 2023 (previously 28 February) to make a voluntary disclosure to HMRC if you used till systems to reduce your tax bill. 

On 10 April 2023, HMRC updated their guidance to note that the online form could continue to be used to make a disclosure after 9 April 2023. This coincided with HMRC beginning to issue one-to-many campaign letters to suspected ESS users from 11 April 2023. See Electronic Sales Suppression one-to-many letters.
