CRS reportable jurisdictions

Exchange relationships are directed, not mutual. Twenty-five jurisdictions in this dataset send information and receive none back, and two thousand relationships run one way only. Pick a jurisdiction and see who it reports to, who reports to it, and where the two lists diverge.

Look up a jurisdiction

Runs in your browser · nothing uploaded

Choose the jurisdiction of the reporting financial institution. The outbound list is what its FIs report on; the inbound list is who sends information about its residents. A jurisdiction appearing in one list and not the other is the case worth looking at.

What this means: a reading of one dataset, not a legal determination. A jurisdiction being listed does not mean every account is reportable, and the operative list for any filing is the one your own tax authority publishes for the reporting period in question — those lists are set domestically and are amended between periods. Effective dates are shown only where the source recorded one, which is roughly a third of relationships. This is not tax advice.

A reportable jurisdiction list is an input, not an answer. The CRS module holds the list per reporting period, applies it to account holder residences and produces validated XML — with a free tier to start.

Direction

Reciprocity is the exception you have to check

The instinct is to treat an exchange relationship as a handshake. In this dataset a fifth of them are not.

Outbound

Who you report on

The jurisdictions your financial institutions must identify and report account holders resident in. This is the reportable-jurisdictions question, and it is the one that drives due diligence and file content.

Inbound

Who reports on you

The jurisdictions that send information about your residents to your authority. Relevant to enforcement risk and to advising clients, and entirely irrelevant to what your own FIs have to file.

One-way

Non-reciprocal by design

Twenty-five jurisdictions here appear only as senders. A jurisdiction with no income tax has nothing to do with the data it would receive, so it commits to sending and not to receiving. That is a feature of the framework, not a gap in it.

Instrument

Four routes, same effect

Most relationships run through the CRS MCAA. Within the EU, exchange runs on Directive 2014/107/EU; some third countries sit under EU agreements; and a minority rest on bilateral competent authority agreements.

Scope

What this tool does, and what the data will not support

Being explicit about the limits of the source matters more here than on a calculator, because the output looks authoritative either way.

It doesRead the dataset faithfully

  • Separates outbound from inbound rather than presenting one list.
  • Flags every relationship that runs in one direction only.
  • Names the legal instrument for each relationship.
  • Shows the effective period start where the source recorded one.
  • Normalises four spelling variants in the source instrument field, including a misspelling of Cyprus, so counts are not split across duplicates.
  • Runs entirely in your browser against an embedded copy of the data.

It does notReplace your authority's list

  • Confirm current activation status. The source's active flag is empty on every row, so every relationship is shown as present and none can be shown as suspended.
  • Give an effective date for the two thirds of relationships where the source recorded none.
  • Reflect changes made after the file was supplied.
  • Determine whether a particular account or account holder is reportable.
  • Cover FATCA, which is bilateral with the United States and works differently.
  • Produce anything you can file.

The operative list is domestic

An exchange relationship existing at OECD level is a precondition, not the obligation. What binds a financial institution is the list of reportable jurisdictions its own authority has specified for the reporting period, and those lists are amended between periods. Use this to understand the network and to sense-check; use the domestic list to file.

Classify an entity

Nothing you select here leaves your browser

The dataset is embedded in the page and every lookup runs on your own machine. No query is sent to REGREP or to anyone else, and nothing is logged.

That is deliberate. Which jurisdictions you are checking is itself informative, and it is not something we want to hold.

Questions

About exchange relationships

Why are outbound and inbound different?

Because an exchange relationship is a pair of unilateral commitments, not a single mutual one. A jurisdiction can undertake to send information without undertaking to receive it, and several do — typically those with no personal income tax, which would have no use for incoming data. Treating the relationship as symmetric produces a reportable-jurisdictions list that is wrong in both directions at once.

Is this the list I file against?

No. The list that binds a financial institution is the one its own tax authority specifies for the reporting period, and it is amended between periods. An OECD-level relationship is necessary for exchange but is not itself the domestic obligation. This tool is for understanding the network and sense-checking a domestic list, not for replacing it.

Why do some relationships show no effective date?

Because the source records one for roughly a third of them. Where it does, the tool shows the year the relationship took effect for taxable periods; where it does not, the field is left blank rather than filled with a guess. A blank means the source is silent, not that the relationship is recent.

Can I tell whether a relationship has been suspended?

Not from this data. The source carries an active flag, but it is empty on all 10,229 rows, so it cannot distinguish a live relationship from a suspended one. Every relationship in the file is shown as present. If suspension matters to your analysis, check the OECD's published status directly.

What are the four legal instruments?

The CRS Multilateral Competent Authority Agreement, which covers the large majority; Directive 2014/107/EU, which governs exchange between EU member states; agreements between the EU and certain third countries; and bilateral competent authority agreements where jurisdictions have contracted directly. The instrument changes the legal basis and the amendment mechanics, not the substance of what is exchanged.

Does a relationship mean every account is reportable?

No. It means information can flow. Whether a particular account is reportable depends on the account holder's tax residence, the entity classification where the holder is an entity, the controlling persons behind a passive entity, and the due diligence outcome. The jurisdiction list tells you which residences matter; it does not tell you what to report.

Knowing the network is not the same as filing against it.
