CRS participating jurisdictions: 100+
UAE: participates in CRS
Nigeria: committed CRS participant (FIRS is competent authority)
Philippines: has not fully implemented CRS automatic exchange
USA: does not participate in CRS (uses FATCA instead)

This post explains how CRS works. It is not tax advice. Your specific obligations depend on your residency status, income sources, and the tax treaties between Nigeria and the countries where you hold accounts. Consult a qualified tax adviser in Nigeria and in any country where you hold accounts or are resident before making any decisions.
If you have a bank account in the UK, Germany, UAE, Mauritius or any of 100+ other countries, that account is being reported to your home country's tax authority every year - automatically, without you being notified. This is the OECD Common Reporting Standard (CRS). Here is exactly how it works.
What CRS is
The Common Reporting Standard (CRS) is an OECD framework for automatic exchange of financial account information between countries. It was developed in 2014 and has been adopted by over 100 jurisdictions.
What gets reported:
- Account balances at year end
- Interest earned
- Dividends received
- Proceeds from sales of financial assets
- Other income credited to the account
Who reports it: Banks, brokers, insurance companies, investment funds and other financial institutions in participating countries.
Who receives it: The tax authority of the account holder's country of tax residence.
How often: Annually, automatically.

How it works in practice
Step 1 - Your bank asks for your tax residency
When you open a foreign bank account, the bank asks you to complete a self-certification form declaring your country of tax residence. This is a legal requirement under CRS.
Step 2 - The bank reports to its local tax authority
At the end of each year, the bank sends your account information to the tax authority of the country where the bank is located (e.g. HMRC in the UK, the Federal Tax Authority in the UAE).
Step 3 - The local tax authority sends it to your home country
The local tax authority sends the information to the tax authority of the country you declared as your tax residence. If you declared Nigeria, it goes to FIRS.
Step 4 - FIRS receives the information
FIRS receives your account balance, interest, dividends and other income from every CRS-participating country where you have accounts and declared Nigerian tax residency.
Which countries participate
CRS participating jurisdictions include:
- All EU member states (UK, Germany, France, Ireland, Portugal, Spain, Italy, Netherlands, etc.)
- UAE (Dubai and all emirates)
- Australia, New Zealand, Canada
- South Africa, Mauritius, Seychelles, Rwanda
- Nigeria (as a receiving jurisdiction)
- Japan, South Korea, Singapore, Hong Kong
Non-CRS or limited CRS jurisdictions:
- USA - uses FATCA (its own system) instead of CRS
- Philippines - has not fully implemented CRS automatic exchange as of 2026
- Panama - signed but limited exchange partners
- Bahrain - signed but limited exchange partners
Important: Non-CRS does not mean zero reporting risk. These countries can still share information on request under anti-money laundering (AML) frameworks. The difference is automatic vs on-request.
Nigeria and CRS
Nigeria is a committed CRS participant. The Federal Inland Revenue Service (FIRS) is Nigeria's competent authority for CRS.
What this means: FIRS receives automatic annual reports from all CRS-participating countries about Nigerian tax residents' foreign accounts.
FIRS enforcement: FIRS enforcement of CRS-reported information is currently limited in practice. However, Nigeria is subject to OECD Global Forum peer reviews, and enforcement capacity is growing. Do not structure your finances on the assumption that FIRS will not act on CRS data.

The self-certification - the most important form you will sign
When you open a foreign bank account, you sign a self-certification form declaring your tax residency. This form determines where your account information is sent.
If you declare Nigeria: Your account is reported to FIRS.
If you declare UAE (because you genuinely live there): Your account is reported to the UAE Federal Tax Authority - which has no personal income tax, so there is no tax consequence.
If you declare incorrectly: Providing false information on a CRS self-certification form is a criminal offence in most jurisdictions. Banks are required to verify your declaration against other information they hold about you.
What CRS does not cover
CRS covers financial accounts. It does not automatically cover:
- Real estate ownership (reported separately in some jurisdictions)
- Cryptocurrency holdings (not yet covered by CRS, though this is changing)
- Cash held outside the banking system
- Business ownership (though dividends from businesses are covered)
