What is MARD?

MARD (Mutual Assistance in the Recovery of Debt) is an arrangement which allows a relevant authority in another country to ask HMRC for assistance in either:
- obtaining information
- serving legal documents
- recovering a tax or duty debt
where the defaulting taxpayer is living in, or has assets in, the UK. There are a number of different MARD arrangements in place, but all are reciprocal.

This guidance refers only to the recovery arrangements made with countries under the Council of Europe (CoE) / Organisation for Economic Co-Operation and Development Convention (OECD) and Double Taxation Agreements (DTA) for tax and duty debts. For information on the MARD arrangements with other members of the EU see DMBM560010 (https://www.gov.uk/hmrc-internal-manuals/debt-management-and-banking/dmbm560010). For information on the MARD arrangements under the EU Social Security Regulation see DMBM560500. (https://www.gov.uk/hmrc-internal-manuals/debt-management-and-banking/dmbm560500)

The Law and Regulations

There are two routes:
- Council of Europe (CoE) / Organisation for Economic Co-Operation and Development (OECD) Convention
- a bilateral arrangement, typically an Article within a Double Taxation Agreement
Legislation that applies to recovery of debts

HMRC powers to recover taxes and duties in the UK when requested to do so by a country under either of these routes are contained in the following legislation:

Section 173 Finance Act 2006

SI xx-xxxx-xxxx ‘The Recovery of Foreign Taxes Regulations 2007’

SI 794/10 ‘The Recovery of Foreign Taxes (Amendment) Regulations 2010’.

Council of Europe (CoE) / Organisation for Economic Co-Operation and Development (OECD) Convention

The CoE / OECD Convention on Mutual Administrative Assistance in Tax Matters sets out the basis for the agreement.

The Convention is given effect in UK law by SI 2126/07 ‘The International Mutual Administrative Assistance in Tax Matters Order 2007’ and SI1079/11 ‘The International Mutual Administrative Assistance in Tax Matters Order 2011’.

It came into force on 1 May 2008.

Double Taxation Agreements

The documents which set up the basis for the arrangement are typically either:
- a Double Taxation Agreement (DTA) between the UK and another country; or
- a Protocol amending the DTA to include debt recovery provisions if these were not covered by the DTA when it was first signed.
The DTA and any protocol are given effect in UK law by means of a Statutory Instrument.

Memorandum of Understanding / Mode of Application

In addition, the operational detail of how assistance will be given can be agreed and set out in the form of a Memorandum of Understanding (MOU) or Mode of Application (MOA), although this is not a legal requirement.

Countries covered

All those countries where the OECD Convention is in force, and which have not entered a reservation on assistance in collection.

All those countries with which the UK has agreed reciprocal recovery under a DTA or a Protocol amending a DTA.
