An authority enquiry requires a clear explanation supported by consistent records. We help businesses assess the issue, organise evidence and prepare technical responses - from first information request through reconsideration and dispute - with specialist legal or authorised representation coordinated when the matter requires it.

Focused expertise for your requirements
Clear analysis, supported by your records

An information request, audit notification or assessment has arrived and the response clock is running.
You have found an error and need to understand the correction routes and their consequences.
A penalty or decision looks wrong and you want the realistic options assessed before deadlines pass.
A significant position needs a written technical defence prepared before anyone asks for it.
Tax Regulatory & Controversy
We identify the documents, calculations and explanations needed to support significant tax positions. A readiness review highlights missing evidence and inconsistencies so the business can address them before or during a review.
We run your significant positions through a simulated review: for each one, does the evidence exist, is it retrievable, do the numbers reconcile and does everyone tell the same story? Gaps are fixed while there is still time to fix them, and the resulting defence file means an actual review starts from organisation rather than panic.
You receive: A position-by-position readiness assessment with a completed defence file and gap-closure plan.
We help interpret requests, allocate information-gathering responsibilities and prepare responses. The focus is a complete, accurate and consistent submission, with material assumptions and open points identified for management rather than concealed.
We decode exactly what is being asked and why, split the request into owned tasks with deadlines, and quality-check the assembled response for completeness and consistency with prior filings before submission. Where information is genuinely unavailable or an earlier explanation needs adjusting, we address it deliberately rather than leaving it to be discovered.
You receive: A managed response process with a tracked request register and a reviewed, consistent submission.
We assess the relevant facts and legal framework and prepare a reasoned explanation of the position adopted. The paper identifies evidence, counterarguments and uncertainty so management and its representatives can evaluate the matter realistically.
We build the argument the way it will be tested: full factual chronology, the legal framework applied to those facts, the supporting evidence indexed against each claim - and an honest treatment of the counterarguments and remaining uncertainty. A paper that concedes nothing convinces no one; ours are written to be relied on.
You receive: A reasoned technical position paper with an indexed evidence annex and candid risk assessment.
We help frame a suitable technical question and assemble the factual and interpretative material required for an application. The service addresses the request and follow-up process; it cannot promise a favourable interpretation or ruling.
The framing of the question largely determines the usefulness of the answer, so we invest there first - precise, complete and honest about the facts. We then compile the factual annexes and the interpretative analysis, and manage follow-up questions during the review so the process reaches an answer you can actually apply.
You receive: A framed application with complete factual and technical annexes, managed through to response.
We assess identified errors, quantify relevant differences and review the available correction route. Support includes preparing workings, documenting the reason for the correction and recommending process changes to reduce recurrence.
We establish the full extent of the error across every affected period and entity - partial disclosure creates its own risks - quantify the differences with workings that survive scrutiny, and prepare the disclosure with a clear account of cause and correction. The engagement closes with the process fix, because repeating the same disclosure twice is avoidable.
You receive: Quantified correction workings, a prepared disclosure and a recurrence-prevention recommendation.
We review the decision and relevant evidence and help prepare the grounds and supporting material for an available application. Eligibility, procedural conditions and deadlines must be checked for the specific matter; relief is not guaranteed.
We give you a realistic merits view first - where the decision is genuinely challengeable and where it is not - then prepare the application: grounds argued against the specific reasoning of the decision, evidence organised to support each ground, and the procedural conditions and deadlines tracked so form never defeats substance.
You receive: A merits assessment and a complete, deadline-tracked application with argued grounds and evidence.
We assist with factual chronologies, technical analyses, economic evidence and reconciliation schedules. For proceedings requiring legal representation, we work alongside appropriately qualified counsel rather than presenting tax advisory support as unrestricted rights of audience.
We produce the technical backbone counsel builds on: the agreed and disputed facts separated, every figure reconciled between filings, correspondence and accounts, economic analyses prepared to evidential standard and technical briefings that put counsel fully inside the tax issues. Weaknesses are identified internally first - the other side will find them anyway.
You receive: A litigation support pack: chronology, reconciliations, economic evidence and counsel briefing materials.
We assess how a tax adjustment in one jurisdiction affects the group elsewhere and help prepare the information needed for relevant resolution discussions. Treaty-based procedures require separate eligibility and procedural analysis in the countries concerned.
When one country adjusts, we map the knock-on effects across the group - double taxation created, positions elsewhere contradicted, filings needing amendment - and prepare the consistent information set that any resolution procedure will demand, coordinating the advisers in each jurisdiction so the group argues one coherent case, not several conflicting ones.
You receive: A group impact map and a coordinated, consistent information pack for resolution proceedings.
