Types of Disclosures
It is important to note that there are two main ways to make a disclosure, namely voluntary disclosure or Prompted Disclosure:
Voluntary Disclosure
Voluntary disclosure means you contact the HMRC prior to any letters or notifications from the HMRC Worldwide disclosure facility. You benefit in this case as the penalties may be lighter due to your diligence and proactiveness in attempting to resolve unpaid tax issues. This type of disclosure has a standard penalty of 200% PLR (Potential Lost Revenue), however a minimum PLR of 100%. Therefore, it is favorable to voluntarily disclose to the HMRC before they contact you.
Prompted / Non-Voluntary Disclosure
The HMRC have been continuously sending out letters as of 2020 to individuals that are classified as “at-risk”. These letters are referred to as “nudge” letters and serve as an opportunity for individuals to send in documentation of having all tax affairs in order, or to disclose any unpaid or inaccurate tax payments. This type of disclosure has a standard of penalty of 200% PLR (Potential Lost Revenue), however a minimum PLR of 150%. This means it is at least a 50% higher penalty than when voluntarily disclosed.
How to Make Voluntary Disclosure
It is recommended that you make a voluntary disclosure as soon as you realise there may be discrepancies in offshore tax paid, or any unpaid taxes relating to international income. The HMRC is more likely to rule on lighter penalties on those who voluntarily disclose.
Step 1: Reach Out To Your Accountant

An accountant can assist you in sorting through your finances and helping you to possibly lower the penalties paid.
