Who regulates bookkeepers

No single regulator licenses bookkeeping in the UK, but a bookkeeper working for clients is an accountancy service provider under the Money Laundering Regulations and must be supervised either by a recognised professional body or by HMRC. Bookkeepers who deal with HMRC for paying clients must also register with HMRC as tax advisers and follow its standard for agents. Membership of a body such as AAT, the Institute of Certified Bookkeepers or the Institute of Accountants and Bookkeepers adds its own rules on top.

Is bookkeeping a regulated activity?

Bookkeeping is not a reserved activity in the way that statutory audit or insolvency work is, and nothing stops a person setting up as a bookkeeper without a qualification. ICAEW’s consumer guidance makes the same point about the word “accountant”: legally anyone can use it. Regulation of bookkeepers therefore comes from three directions rather than one: anti money laundering law, HMRC’s rules for anyone who deals with it on clients’ behalf, and the rules of any professional body the bookkeeper chooses to join.

The wider comparison between qualified and unqualified practitioners is covered in regulated vs unregulated accountants. This page looks at bookkeepers specifically.

Why do the Money Laundering Regulations cover bookkeepers?

The Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017 apply to “external accountants”, defined in regulation 11 as a firm or sole practitioner who by way of business provides accountancy services to other persons. HMRC’s guidance on accountancy service providers explains that these services include recording, reviewing, analysing, calculating and reporting on financial information for other people, and it names professional bookkeeping services expressly. A bookkeeper who also helps with tax returns will usually be a “tax adviser” under regulation 11 as well.

Being in scope brings the full set of duties: a firm wide risk assessment, customer due diligence, written policies, training, record keeping and suspicious activity reporting. Under regulation 26, the beneficial owners, officers and managers of an external accountancy firm, and a sole practitioner, must be approved by the firm’s supervisory authority.

Who can be a bookkeeper’s AML supervisor?

Regulation 7 makes each professional body listed in Schedule 1 the supervisor for its own members, and makes HMRC the supervisor for external accountants and tax advisers who are not supervised by one of those bodies. Schedule 1 includes two bodies focused on bookkeeping: the Institute of Certified Bookkeepers and the Institute of Accountants and Bookkeepers. The latter replaced the International Association of Bookkeepers in the Schedule from 30 June 2026, although HMRC’s own list had used the new name since March 2023. The Association of Accounting Technicians, ACCA, ICAEW, ICAS, CIMA, the Institute of Financial Accountants, the Association of Taxation Technicians and the Chartered Institute of Taxation are also listed.

HMRC’s guidance says an accountancy service provider must register with HMRC unless it is already supervised by a professional body, or all its customers are themselves supervised accountancy firms or banks and strict conditions are met. In practice that gives a bookkeeper three routes:

Route	Who it suits	What it involves
Professional body supervision	Members of a Schedule 1 body that supervises practising members	The body’s licensing or practising rules, AML monitoring visits and annual returns
HMRC supervision	Bookkeepers not supervised by a professional body	Online registration, approval of owners and managers, an annual fee for each premises
Working only under another firm’s supervision	Subcontractors whose only customers are supervised accountancy firms or banks	No direct dealings with the end clients, inclusion in the customer firm’s AML procedures, and a written contract confirming this

The professional body supervisors are themselves overseen by OPBAS, the Office for Professional Body Anti Money Laundering Supervision, which is housed within the FCA. In October 2025 the government announced that the FCA will take over AML supervision of accountancy service providers; see AML supervision reform.

Is there an exception for virtual assistants?

HMRC operates a concession for virtual assistants who do a small amount of bookkeeping. It applies only if all of these are true: virtual assistance is the main business, annual turnover is under £30,000, no more than 5% of turnover comes from accountancy services, those services support the main business, there is no other activity needing registration, and the work is reviewed by an accountant or bookkeeper who is AML supervised. The assistant must email HMRC a declaration explaining how each condition is met and keep a copy. If the business grows beyond the limits, registration is needed.

What does professional body membership add?

A professional body regulates the person as well as the AML process. AAT, for example, says all self employed members offering bookkeeping or accountancy services to clients must hold an AAT licence, which lets them describe themselves as an AAT Licensed Accountant or AAT Licensed Bookkeeper depending on the services approved. Applicants must show technical competence, meet practice assurance standards and be fit and proper. Licence holders must have professional indemnity insurance, continuity arrangements and client money procedures, and are subject to practice assurance reviews that also test AML compliance. The detail is in AAT licensed accountants.

Members of the Institute of Certified Bookkeepers or the Institute of Accountants and Bookkeepers should check that body’s current practising, insurance and CPD requirements directly with it.

Do bookkeepers need to register with HMRC as tax advisers?

Often, yes. Under the Finance Act 2026 a business that is paid and interacts with HMRC about someone else’s tax affairs must register through an agent services account, unless an exception applies. HMRC’s guidance says this applies even where the business does not see itself as a tax adviser, where tax is not its main function, or where it acts for only one client. A bookkeeper who files VAT returns, sends Making Tax Digital quarterly updates, runs client payroll or phones HMRC for a client is interacting with HMRC. One who only maintains records and passes them to the client’s accountant, and never contacts HMRC, is not. See mandatory registration of tax advisers for the conditions.

Registration also brings the bookkeeper within HMRC’s standard for agents, which lists accountants and bookkeepers among the agents it covers and applies whether or not they belong to a professional body. HMRC will not accept an agent services account application until AML supervision has actually been approved.

What does regulation not cover?

None of these regimes guarantees the quality of a particular set of books. AML supervision checks the firm’s controls for spotting financial crime, not the accuracy of its VAT returns. HMRC’s registration conditions look at the bookkeeper’s own tax compliance, convictions and insolvency, not technical competence. Only professional body membership brings competence requirements, CPD, a complaints and disciplinary process, and in some cases compulsory professional indemnity insurance. A client harmed by an unaffiliated bookkeeper’s error may be left with a civil claim and no regulator to complain to.

Illustration only. Sam is a self employed bookkeeper with eight small business clients and no professional body membership. Sam prepares and submits VAT returns for three of them. Sam must be supervised by HMRC for AML, must have AML supervision approved before applying for an agent services account, and must register as a tax adviser. If Sam joins a bookkeeping body that supervises its practising members, that body replaces HMRC as AML supervisor, but the HMRC tax adviser registration still applies.

What mistakes do bookkeepers make?

Assuming that a small client list or part time work takes them outside the Money Laundering Regulations.
Claiming the virtual assistant concession without meeting every condition or emailing HMRC.
Believing that membership of a body automatically means AML supervision by it; ACCA, for example, only supervises firms in which its practising certificate holders have majority control.
Applying for an agent services account while AML supervision is still pending.
Operating without professional indemnity insurance because no law requires it; see fee protection for bookkeepers for a related cover.
