UK accountability · mostly for researchers and builders

Who checks the checkers — and how you can complain.

A map of how UK tax investigators, auditors and regulators are themselves reviewed, audited and appealed. If HM Revenue & Customs (HMRC — the UK tax office) treated you badly, start with the complaint box below.

How to complain about HMRC See the method

The short version

Unhappy with HMRC? You can appeal a tax decision, or complain about poor service. The routes differ.
Every watchdog here has its own review, complaint or appeal route — or we say we could not map one.
An open investigation or complaint is never proof of wrongdoing.
The framework below is mostly for researchers and builders.

For ordinary people

Unhappy with how HMRC treated you?

To challenge a tax decision: preserve the appeal shown by the notice and governing rule. A statutory review may be available or offered; tribunal timing and any later appeal depend on the exact regime.
To complain about service: HMRC's first and second review, then the Adjudicator, then—where eligible—an MP and the Parliamentary and Health Service Ombudsman (PHSO).
A complaint does not by itself pause a tax, payment or appeal clock and does not replace the decision-specific route.

The principle

Watchdogs follow the same evidence rules they apply to others.

“The observer is also observed” means scrutiny power joins the same evidence discipline it applies to others. It does not mean the investigator and subject are the same legal body, that observation proves motive, or that anybody owes the internet their private life.

The ten questions an honest investigation record must answer

Open for the checklist we hold every watchdog record to — including our own.

Identity

Which exact public institution is acting, in what official capacity and jurisdiction?

Authority

Which statute, appointment, contract, terms of reference or published rule permits the work—and where does it stop?

Commission and money

Who commissioned, funds, appoints, sponsors or supplies the observer? Each relation keeps its own meaning.

Scope

Which organisation, programme, decision, period and question are actually under examination?

Method

What was gathered, selected, excluded, tested and limited? Is the method public and versioned?

Words

Is this an allegation, provisional finding, final finding, auditor opinion, tribunal decision or TaxSorted analysis?

Doings

What public procedural action happened, which exact institution acted on which declared subject, and where did any referral go?

Response

What did the observed institution publicly accept, dispute, correct or appeal?

Challenge

Who can review, hear a complaint, audit, inspect, overturn, recommend or judicially review the observer?

Our hand

Why did TaxSorted include, omit, paraphrase or compare this record, and how can that editorial act be corrected?

Power in a graph

Start with real institutional routes, not a conspiracy hairball.

A network edge must be published and typed. Funding is not control; appointment is not operational direction; cooperation is not collusion; a complaint is not a finding.

The Adjudicator: independence has structure

The Adjudicator is personally independent and is not an HMRC officer.

The published service agreement also says the office uses HMRC staff, funding, premises and legal personality. Both facts belong in the graph.

Check the official source

Charity Commission: opening is not a verdict

A regulatory concern can become a statutory inquiry, with evidence and protective powers, then a published outcome.

Opening an inquiry is not itself a finding of wrongdoing. Service complaints, Commission decision review and Tribunal appeal have different scope and clocks.

Check the official source

The National Audit Office (NAO): the auditor is audited

The Comptroller and Auditor General (C&AG) and the NAO audit public spending and report to Parliament. The Public Accounts Committee (PAC) uses that work for scrutiny.

The Public Accounts Commission scrutinises the NAO budget and appoints its external auditor; that auditor also performs an annual value-for-money study of the NAO.

Check the official source

Electoral Commission: process states matter

Assessment, then investigation, then a determination or no determination, representation, sanction, and possible court appeal.

Police retain parts of the criminal lane. Published closed cases include no-offence and no-determination outcomes as well as breaches.

Check the official source

Private investigator is not a magic licence

TaxSorted's reading of the current Security Industry Authority (SIA) licensable-activity list: private investigation is not itself named.

That means only that this specific SIA licence category is absent, not that the work has special powers or immunity. Data-protection, criminal, civil and activity-specific rules still apply.

Check the official source

Words and doings

Keep the states separate or the record lies.

“Their words” means a dated, attributed, human-reviewed faithful paraphrase with a link back to the publisher. Exact source bodies are not copied by default. Corrections and reversals must be as visible as the original record.

A bounded experiment loop

Try things, check the evidence, keep an off-switch.

Explore a bounded question freely; findings earn weight through evidence, counterevidence, limits, challenge and correction. This is a controlled inquiry loop, not ambient surveillance.

1 · Hypothesis
Ask one falsifiable public-interest question.
2 · Pilot
Choose one small territory and a tiny field allowlist.
3 · Observe
Collect public institutional artefacts, not private traces.
4 · Evidence
Attach exact identity, source, date, method and limits.
5 · Counterevidence
Find the subject response and a real challenge route.
6 · Risk
Test rights, privacy, observer effect, bad joins and hostile reuse.
7 · Decide
Observe, adopt, adapt or discard—and publish why.
8 · Stop
Abort, contain and roll back when a wall is hit.

The wall

Transparency must not become surveillance wearing a halo.

No named-investigator roster, biography, home, private contact or individual pay dossier.
No inferred beliefs, personality, honesty, trust, motive, affiliation or private network.
No unpublished or operational case files, witness, complainant or suspect data, tactics or private submissions.
No guilt, hypocrisy, watchdog, integrity or virtue score.
No name-, address-, domain- or person-based institutional join.
No inference that a complaint, funding link, appointment or inquiry proves wrongdoing.

For developers

The machine framework, its schema and the honest release state.

The contract is live. Investigation records are deliberately zero-row.

Builders can align now around five collections: institutional relations, investigation engagements, public actions, institutional responses and coverage gaps. Real rows stay closed until source-by-source rights, confidential correction, operational privacy review, review-audit proof, monitored emergency stop and rollback are real—not strings claiming they happened.
