Support from the first letter, because the position taken early usually determines how the matter ends.
Objection windows are strict. A right lost to timing is generally not recoverable by the strength of the underlying argument, however good that argument is.
What is said before the exposure has been assessed constrains everything afterwards. Volunteering material that was not requested is the most common way a manageable matter becomes a difficult one.
The amount in dispute is rarely static. A matter allowed to drift can grow materially even where the original position is eventually accepted in part.
Identify every running deadline first, then assess the actual exposure as distinct from what has been asserted, before any substantive response is sent.
Determine what is genuinely arguable, what is merely uncomfortable, and what should be conceded early because contesting it costs more than it saves.
Managed correspondence and, where appropriate, a formal objection prepared and filed within the applicable window.
Negotiate where that produces the better outcome, and coordinate with admitted counsel where a matter proceeds to formal proceedings.
“I will explain it to them and it will go away.”
An unconsidered early explanation is the most common way a manageable matter becomes a difficult one. What is volunteered before the exposure has been assessed constrains everything afterwards.
“The deadline is probably flexible.”
Objection windows are strict, and a right lost to timing is generally not recoverable by the strength of the underlying argument, however good that argument is.
“Admitting a historic issue will make it worse.”
Frequently the opposite. The treatment of a voluntary disclosure is generally materially better than the treatment of the same issue once discovered independently, though it is a judgement on the specific facts.
The outcome of a tax dispute is usually shaped well before anyone reaches a formal stage. It is shaped by what was said in the first response, by what was volunteered without being asked, and by whether the position taken at the outset can be sustained once more is known. Responses sent before the exposure has been assessed are the single most common way a manageable matter becomes a difficult one.
Marco Aalbers spent more than a decade working within the tax inspectorate before advising from the outside. That experience is directly relevant here, not because it produces influence, which it does not and should not, but because it informs a realistic assessment of how a position will be received, which arguments carry weight, and where a matter is genuinely arguable as opposed to merely uncomfortable.
Deadlines govern this work in a way they do not govern advisory. Objection windows are strict, and a right lost to timing cannot usually be recovered by the strength of the underlying argument. Any matter with a running deadline is treated as urgent from the first contact.
It is worth stating plainly what the inspectorate background does and does not provide, because it is easily misread. It confers no influence, no access and no special treatment, and any suggestion otherwise should be treated with suspicion by a client wherever they encounter it. What it provides is calibration: an informed sense of how a file is read, which arguments are routinely made and routinely rejected, where a position is genuinely arguable, and when a matter is better resolved than contested. That calibration is most valuable at the earliest stage, when the range of options is widest.
Proactive disclosure deserves its own consideration, because the instinct to say nothing is strong and frequently wrong. Where a historic problem has been identified internally, the treatment of a voluntary disclosure is generally materially better than the treatment of the same issue once it has been discovered independently. That is a judgement made on specific facts and not a universal rule, but clients are often surprised by how much room exists on one side of that line and how little exists on the other.
Every Private Client engagement opens the same way: a fixed fee review of your current position, delivered as a written memorandum with risks and opportunities ranked and a recommended path. No open ended discovery.
