Around the world, the space for hiding money offshore has been shrinking for years and in 2025 it’s tighter than ever. Global standards like the Common Reporting Standard (CRS) and FATCA mean that financial institutions routinely report account information to tax authorities, who then exchange that data with partner jurisdictions. At the same time, African countries are rapidly strengthening their information systems, often with international support, and domestic reporting channels between banks, central banks and tax authorities are becoming increasingly robust.
South Africa is a perfect example of how these developments converge: automatic exchange of information, domestic oversight by the South African Reserve Bank (SARB), and targeted SARS compliance programmes, including a sharpened focus on crypto-assets.
Below is what taxpayers and advisors really need to know.
The world is sharing more information than ever.
For nearly a decade, tax authorities have been receiving automatic data on foreign financial accounts under CRS and, for US persons, under FATCA. These systems typically capture:
- Account holder identity
- Account numbers
- Year-end balances
- Interest, dividends and other income flows
The key point: many jurisdictions now exchange this information with one another each year. While reporting varies by country and whether an account is “reportable,” the trend is unmistakable; more data, more partners, more transparency.
On top of automatic exchange, double tax agreements (DTAs) and tax information exchange agreements (TIEAs) allow for information-on-request and spontaneous exchange. These channels are frequently used to clarify cross-border ownership structures, confirm residency, or verify the source of funds.
Africa’s rapid uptake: strengthening the “domestic plumbing”
African countries have been steadily expanding their participation in global transparency initiatives through the Africa Initiative of the OECD Global Forum and related regional programmes.
The result is that a growing number of African jurisdictions now have:
- Legislative frameworks for AEOI
- IT systems to receive financial account data
- Operational procedures for using the information in audits
- Expanding domestic pipelines between banks, financial intelligence units, central banks, and tax authorities
Not every country is at the same stage, but the regional direction is clear: greater visibility of cross-border financial flows and tighter alignment between tax and financial supervision.
Governments are adding AI and analytics to the mix
Collecting data is only half the battle, using it effectively is the game-changer.
Countries like France have been open about deploying machine-learning tools to detect anomalies, match third-party data to taxpayer filings and identify undeclared income or assets (including property). OECD surveys show that many administrations globally are actively piloting or scaling similar analytics tools.
This means tax authorities can now:
- Match AEOI data to tax returns more quickly
- Identify inconsistencies with higher accuracy
- Prioritise high-risk taxpayers for audit
- Issue targeted nudges and verification requests
In other words: smarter systems mean faster detection.
South Africa: international exchange meets domestic oversight
South Africa illustrates how international standards and domestic systems reinforce each other:
CRS, FATCA and cross-border transparency
SARS administers CRS and FATCA domestically. South African financial institutions submit detailed reports to SARS, which then exchanges the data with participating jurisdictions. SARS has publicly stated that it uses this information in its compliance programmes.
SARB, banks and exchange-control oversight
SARB continues to tighten exchange-control processes, and authorised dealers must increasingly align cross-border payment approvals with tax compliance status. In practice, this reduces the ability to externalise funds where tax affairs are not in order.
While SARS and SARB remain distinct institutions, their processes and oversight requirements are more coordinated than they were previously, meaning fewer gaps through which funds can quietly flow.
Crypto reporting and SARS’ compliance focus
SARS has clarified that ordinary tax rules apply to crypto-assets, and crypto gains/losses must be declared. Recent compliance programmes have included:
- Public warnings about non-declaration
- Requests for crypto transaction records during audits
- Coordination with exchanges and service providers as global standards (including the OECD’s new crypto reporting rules) come online
Crypto is no longer uncharted territory, the enforcement risk has increased materially.
What this means for taxpayers
Visibility is increasing
Whether through CRS, FATCA, domestic bank reporting, or supervisory data, tax authorities are receiving more information than ever. Not every account is reportable and not every jurisdiction exchanges with every other, but the likelihood of detection is significantly higher.
Crypto must be declared
SARS is now treating crypto similar to any other financial asset. Non-disclosure is a compliance risk, not a loophole.
Cross-border remittances face greater scrutiny
Banks and authorised dealers will increasingly expect tax compliance to be demonstrable before facilitating transfers.
Three key takeaways
1. Information sharing is now the norm, not the exception.
Automatic exchange, EOI treaties and domestic reporting give tax authorities unprecedented visibility.
2. Africa is accelerating, the data pipes are being installed.
More jurisdictions have the legal and technical infrastructure to use the information effectively.
3. South Africa is tightening the net, especially on crypto.
SARS, SARB and banks form a more coordinated ecosystem, and crypto enforcement is clearly rising.
Final thoughts
The days of relying on opaque structures, offshore bank secrecy or unreported crypto holdings are behind us. Tax authorities in Africa and globally have better tools, more data and smarter systems than ever before. For taxpayers, the safest strategy is full disclosure and proactive compliance. For advisors, early housekeeping and coordinated planning across tax and exchange control are essential.
