Common Reporting Standard After Eight Years

The Common Reporting Standard (CRS) has been in force since 2017 and now covers more than 100 participating jurisdictions. The technical guidance has matured; the reporting flows are routine; the data-quality issues that affected the first few years of reporting have largely been resolved.

For a private client, the practical effect of mature CRS reporting is that residency in one jurisdiction and account-holding in another is, in 2026, visible to the tax authorities of both. The reporting is annual, in arrears (with a lag of nine to fifteen months typically); the formats are standardised; the receiving authorities' tools for processing the inbound data have improved sharply since 2020.

Three operational realities now apply.

First, the matching between CRS data and the receiving authority's own taxpayer records is largely automated. A new account opened in jurisdiction A by a resident of jurisdiction B is, after the CRS lag, matched to the taxpayer's record in B. The match is now done at the level of name, date of birth, and tax identification number; matches with high confidence are accepted into the receiving authority's data without manual review.

Second, the data the receiving authority holds informs its risk-rating of the taxpayer. A taxpayer with significant cross-border account balances, declared properly, is risk-rated routinely. A taxpayer whose CRS data is inconsistent with their declared position is flagged for review.

Third, the audit's reading of a private client's CRS footprint is now meaningful in a way it was not five years ago. The audit reads the client's known accounts, the jurisdictions in which they are held, and the reporting status of each (whether the account-holding institution is a Reporting Financial Institution under the local CRS implementation). Where the client holds accounts they were unaware would be reported (some pension-style products, some insurance-wrappers, some intermediary structures), the audit identifies them.

What the audit does not do is replicate the client's tax position; that is properly the work of tax counsel. What the audit does is identify the picture that CRS has now placed on the public record (or, more precisely, on the tax-authorities' records) about the client's cross-border position.
