What is an HMRC advance ruling?
Answered 17 March 2026
HMRC Guidance / Practice
An HMRC advance ruling (also referred to as a clearance) is an agreement or written confirmation made between HMRC and a taxpayer in advance of a transaction or event, upon which the taxpayer can rely regarding their tax position.
Definition and Nature
In international tax terminology, a "ruling" refers to "an agreement made between a tax authority and a customer, upon which the customer can rely." In HMRC's context, this includes both statutory and non-statutory clearances, and other types of assurance about a customer's tax position.
The key characteristic of an advance ruling is its timing: it must be provided in advance of the tax return covering the event or transaction in question. Settling an enquiry or confirming the tax treatment of a past transaction during an enquiry does not constitute a ruling.
The Non-Statutory Clearance Service
HMRC's Non-Statutory Clearance Service provides written confirmation to customers "where there is genuine uncertainty in relation to the application of tax law to a specific transaction or set of circumstances." It is available to both business and non-business customers.
HMRC will not use the service to:
- Help where there are no genuine points of uncertainty;
- Provide tax planning advice; or
- Advise on transactions designed to avoid or reduce a tax charge.
What a Ruling Covers
A clearance letter "reflects HMRC's view of the tax consequences of the specific transaction/circumstances." The taxpayer is entitled to act on HMRC's view or on their own view of the appropriate tax treatment and self-assess accordingly.
Importantly:
- The ruling is not for general application — it only relates to the specific circumstances and facts disclosed.
- "In the vast majority of cases a clearance we give will be correct in law and therefore binding on HMRC." However, there are some circumstances in which HMRC can no longer be bound by a clearance it has given.
- HMRC reserves the right to change its view in the future, and where tax avoidance is suspected, HMRC reserves the right to review the tax consequences and form another view.
Statutory vs. Non-Statutory Clearances
There are both statutory clearances (provided for by specific legislation, e.g. in relation to certain investment fund regimes) and non-statutory clearances provided under HMRC's general clearance service. HMRC also provides specialist advance rulings such as Advance Pricing Agreements (APAs) and advance thin capitalisation agreements for transfer pricing matters.
International Dimension
Certain advance rulings (particularly those with a cross-border element) are subject to automatic or spontaneous exchange with other tax authorities under the OECD's Base Erosion and Profit Shifting (BEPS) Action 5 framework, to increase transparency and tackle international tax avoidance.

We should only exchange rulings where we provide them in advance of the tax return covering the event or transactions in question (IEIM520800). This means that settling an enquiry, or otherwise confirming the tax treatment of a transaction or event in the course of an enquiry, is not in itself a ruling to be exchanged. If in the course of the enquiry we give agreement or an opinion on which the customer can rely about the treatment of future transactions, this will be a ruling that we need to ex
