CRS Reporting

This page explains why you may have been contacted by your local tax authority in connection with CRS reporting and how the reported figures relate to your account data. CRS reports contain standardized information that is shared with tax authorities and may differ from the figures shown in your Activity Statement. These differences are expected and do not indicate an error.

What is CRS reporting?

The Common Reporting Standard (CRS) is an international framework developed by the OECD for the automatic exchange of financial account information between tax authorities.

Financial institutions are legally required to report certain account data to their local tax authority, which may then share this information with the tax authorities of the account holder’s country of tax residence.

Why has my tax authority contacted me?

Being contacted by your tax authority in connection with CRS data is a standard regulatory process and does not indicate an error or wrongdoing.

Tax authorities may contact you to:

Reconcile reported financial data
Request clarification on specific amounts
Compare CRS data with your submitted tax return

Important: The information reported under CRS may not always match the figures shown in your activity statement, as the two can be based on different reporting rules and purposes.

Difference: CRS Report vs. Activity Statement

The CRS Report and the Activity Statement serve different purposes:

The CRS Report is a standardized report sent to tax authorities and contains total gross proceeds.
The Activity Statement reflects your actual trading activity, including gains, losses, and costs. Some of the gross amounts included in the CRS report may be shown in aggregated form in the cash report section of the activity statement.

Differences between the two documents are expected and do not indicate an error.
