CRS / CFC stocktake: take stock first, then decide whether to move
The most expensive mistake on this subject is not "having made no arrangements" but "moving before taking stock". Where information is already transparent, hurriedly shifting accounts, changing shareholdings or dissolving entities leaves a trail that is harder to explain — and timing matters a great deal. So the first step is always to take stock. These five sheets set out what has to be captured: residence, accounts and holdings, offshore entities, and filing gaps. Fill them in first; then discuss whether anything should change.
01It does only the first of three steps
The sequence set out in our article is take stock → assess the gap → then redesign. This workbook does the first step only, and deliberately not the other two — discussing changes before taking stock is treating assumptions as facts.
Why the order is worth insisting on: structural change is better done early than late, but it is far worse to act before the position is clear. Transferring shares, closing accounts, changing control — these actions leave a trail of their own, and a position that was controllable and explainable can become hard to explain because of one hasty adjustment.
02What the five sheets capture
Each sheet exists because of a specific way this goes wrong:
- Read this first — what the workbook answers and what it does not.
- Residence — the starting point for everything else. The two jurisdictions apply different tests, and you can be treated as resident in both, in which case the treaty tie-breaker applies. Until residence is settled, nothing downstream can be assessed.
- Accounts and holdings — the point here is that identification is not limited to personal accounts. The controlling persons behind a company account are within scope as well: putting a company in between does not change the look-through logic. So this sheet covers accounts held in company names too.
- Offshore entities — control, effective tax burden and substance are looked at together. An entity enjoying a local exemption has a low effective burden, which makes attention more likely rather than less — and that interacts with investment promotion.
- Filing gaps — a gap that already exists matters more than any future arrangement. It is an accomplished fact, and it gets harder to deal with the longer it is left.
03Why every conclusion column is left blank
Almost every judgement here depends on the individual case: how residence is determined, which situations create an entity that must be looked through, how control and tax-burden tests are computed. Building a sheet that lets you tick your way to a conclusion would be the genuinely harmful thing to do — so every cell involving a judgement is amber, and what goes in it is "to be determined", not an answer.
You record the facts (which accounts exist, who holds what, whether profits were distributed); an adviser reaches the conclusion. That division does not work in reverse.
04One thing to note before you start
This workbook will end up holding personal account and shareholding information. It is your own internal material. Keep it as such and do not send it over an unprotected channel; when you want our help with the assessment, we will agree a secure way to hand it over.
The tests, thresholds and exemptions follow the rules and practice currently applied in both jurisdictions. This workbook states no percentages or threshold figures; an individual position has to be assessed by our advisers against residence and the specific facts.
What is in the workbook
- Read this first: what the workbook answers, what it does not, and why taking stock has to come before moving
- Residence factors: time present, permanent home, centre of vital interests, economic interests, the position taken in past filings, and whether dual residence is possible
- Accounts and holdings: including those held in company names, recording the controlling person behind each company
- Offshore entities: control, whether a local exemption applies, how profits have been dealt with, and substance — set out side by side
- Filing gaps: what should have been filed and was not, whether the records are complete, what is missing — with the order of work left to an adviser

Common questions
- My account is in the company's name. Does it still need to be recorded?
Yes. Identification is not limited to personal accounts — the controlling person behind a company account is within scope too. Putting a company in between does not change the look-through logic; what matters is how that company is characterised, and whether it falls into the category that must be looked through.
- The stocktake shows a filing gap. Should I fix it straight away?
Not on your own initiative. Remediation is sensitive to timing, and the wrong order can cost more than the gap did. Gaps also tend to span several years and several entities, so fixing one point in isolation can expose an inconsistency elsewhere. That is why the "order of work" column is left to an adviser.
- Profits have stayed in the Thai company and never been distributed. Will this tell me whether that is a problem?
No — it only helps you lay the factors out: control, whether a local exemption applies, whether anything was distributed, and substance. Whether those together reach a threshold has to be judged against the current rules and the specific facts.
- How long does it take to fill in?
It depends how many accounts and entities there are and how easy the records are to find. "We cannot produce it" is itself a finding — there is a "what is missing" column, and marking the gap is more useful than leaving the row blank. There is no need to wait until everything is to hand before starting.

- General note: the control tests, effective tax-burden thresholds and exemptions under controlled foreign company rules, together with the determination of tax residence and the treaty tie-breaker where dual residence arises, follow the rules and administrative practice currently applied in both jurisdictions. This toolkit states no percentages or threshold figures and does not substitute for an assessment of the individual case. What the workbook produces is an organised set of facts; the conclusion must come from our advisers, taking residence, control, the ownership chain and past filings together.
What the facts add up to, and whether anything should change, depends on residence and the specific case.
