Common Reporting Standard (CRS) Guide for Forex Traders 2026
Your forex broker is a Reporting Financial Institution under the OECD Common Reporting Standard. Every year, it sends your account data to the tax authority in the jurisdiction where you declare tax residence. This guide covers exactly what is reported, when, to whom, and what to do if the data is wrong.
Quick Answer: What Your Broker Reports
Under CRS, your forex broker reports the following to its local tax authority every year, which then forwards it to your tax authority:
- Your name, address, date of birth, and Tax Identification Number (TIN)
- Your jurisdiction of tax residence
- Account balance at 31 December
- Total gross income (interest, dividends, other income credited to the account)
- Gross proceeds from the sale or redemption of financial assets
Timeline: 2025 trading data → broker reports to local authority by ~30 June 2026 → your tax authority receives it by 30 September 2026.
What Is the Common Reporting Standard
The Common Reporting Standard (CRS) is an international framework developed by the OECD and adopted in 2014 for the automatic exchange of financial account information between tax authorities. Over 100 jurisdictions participate, including all 27 EU member states, Norway, Switzerland, and the United Kingdom. The first automatic exchanges took place in 2017.
CRS requires financial institutions — banks, brokers, custodians, certain insurance companies, and investment funds — to identify account holders who are tax resident in another participating jurisdiction and report specified financial data to their local tax authority. That authority then transmits the data to the account holder’s country of tax residence via bilateral Competent Authority Agreements (CAAs).
For forex traders, the practical consequence is straightforward: your broker is a Reporting Financial Institution (RFI). Every year, it compiles data on your account and sends it — not to you, but to the tax authority in the jurisdiction where you declared tax residence when you opened the account (or last updated your self-certification). Your home tax authority then matches this data against your filed return. If there is a discrepancy, an automated enquiry is generated.
Legal basis: OECD Standard for Automatic Exchange of Financial Account Information in Tax Matters (2014), transposed into EU law via Council Directive 2014/107/EU (amending Directive 2011/16/EU, known as DAC2).
What Your Broker Reports Under CRS
CRS reporting is structured. Your broker does not send a narrative — it transmits a fixed set of data fields in CRS XML schema format. The exact fields reported for every reportable account:
| Data Field | What It Contains | Forex-Specific Notes |
|---|---|---|
| Account holder identity | Full legal name, address | As registered on broker KYC documents |
| TIN | Tax Identification Number for each jurisdiction of tax residence | Reported per jurisdiction. Dual residents: TIN for each country. |
| Date of birth | For individual account holders | Used for matching where TIN is absent |
| Jurisdiction of tax residence | Country code(s) where the account holder is tax resident | Determines which tax authority receives the report |
| Account balance / value | Balance at 31 December (or closure date if account closed during year) | Includes cash, margin, unrealised P&L if reported as a single balance. Currency converted to reporting currency. |
| Gross interest | Total interest credited during the calendar year | Includes swap/rollover credits on forex positions |
| Gross dividends | Dividend income credited during the year | Relevant for CFD dividend adjustments on equity CFDs |
| Other income | Any other income credited to the account | Catch-all category. May include rebates, bonuses, or other credits. |
| Gross proceeds | Gross proceeds from sale or redemption of financial assets | For custodial accounts. Captures total proceeds from closed forex/CFD positions, not net profit. |
Critical distinction: gross proceeds vs net profit
CRS reports gross proceeds, not net profit. If you traded EUR 500,000 notional value during the year and made a net profit of EUR 5,000, the CRS report shows the EUR 500,000 in gross proceeds. Your tax authority knows this is gross — but if your filed return shows only EUR 5,000 in gains and doesn’t reconcile against the gross figure, it can trigger an automated mismatch alert. Always ensure your tax return methodology is consistent with how your broker reports.
CRS Reporting Timeline
CRS operates on a fixed annual cycle. The following timeline applies to the 2025 tax year as an example:
1 January – 31 December 2025: Data Collection Period
Your broker records all account activity: balances, income, proceeds. At year-end (31 December), it snapshots your account balance and compiles the annual totals.
January – June 2026: Broker Reports to Local Tax Authority
The broker files its CRS return with the tax authority in its own jurisdiction. Most EU deadlines fall on 30 June, but some are earlier (Finland: 31 January, Denmark: 1 May, Sweden: 15 May, Norway/Spain/UK: 31 May). The broker’s local authority is the intermediary — not yours.
By 30 September 2026: Exchange Between Tax Authorities
The broker’s local authority transmits the data to the competent authority in your country of tax residence. The 30 September deadline is the OECD standard; in practice, bilateral exchanges often occur earlier. After this point, your tax authority holds the data and runs automated matching against your filed return.
October 2026 onwards: Automated Matching & Enquiry
If the CRS data does not match your filed tax return — or if no return was filed — an automated enquiry letter is typically generated. Response timescales vary by jurisdiction (Germany: 30 days; France: 60 days; UK: 30 days). The fact that CRS data triggered the enquiry is usually stated explicitly in the letter.

CRS Due Diligence: Thresholds and What Triggers Flags
CRS imposes different levels of due diligence depending on account type, account value, and whether the account existed before CRS implementation (“pre-existing”) or was opened afterwards (“new”).
Pre-existing Individual Accounts: Balance <$250,000
Simplified due diligence applies. The broker may rely on existing records (address, KYC documentation) to determine tax residence without requiring a new self-certification. However, the account is still reported if the broker determines the holder is tax resident in another CRS jurisdiction based on available data. The $250,000 threshold reduces the due diligence burden on the broker, not the reporting obligation.
Pre-existing Individual Accounts: Balance >$1,000,000 (High-Value)
Enhanced review required. The broker must search electronic records andpaper records for indicia of tax residence in another jurisdiction. The relationship manager (if assigned) must be consulted for actual knowledge of the account holder’s tax status. This is the most thorough tier of CRS due diligence and applies to accounts that exceed $1,000,000 at 31 December of any year.
New Accounts: Self-Certification Required
Every new account opened after CRS implementation requires a self-certification at onboarding. This is the form where you declare your jurisdiction(s) of tax residence and provide your TIN(s). It is the CRS equivalent of the W-8BEN used for FATCA. If you do not complete it, the broker cannot open the account (in most jurisdictions) or must report the account as “undocumented.”
Entity Accounts: Passive NFE Look-Through
If your trading company (OÜ, SIA, UAB, Ltd) is classified as a Passive Non-Financial Entity (Passive NFE) — which it almost certainly is if its primary activity is holding financial assets — the broker must “look through” to identifying the controlling persons(shareholders with >25% ownership or control). The controlling persons’ personal details (name, TIN, residence) are reported alongside the entity account data.
Undocumented Accounts
If the broker cannot determine your tax residence — because you haven’t completed a self-certification and available records are contradictory or incomplete — the account is reported as “undocumented” to all jurisdictions in which the account holder may be tax resident based on available indicia. This means your data could be sent to multiple countries simultaneously. Completing your self-certification is the only way to control which jurisdiction receives your CRS report.
Common CRS Problems for Forex Traders
1. Wrong tax residency on file
The most common issue. You relocated from Germany to Portugal but never updated your broker. The broker continues reporting to BZSt (Germany) instead of AT (Portugal). Germany receives data for an account holder who no longer files there. Result: Germany queries you; Portugal never sees the income and may eventually query the discrepancy when you file a Portuguese return showing foreign broker income they have no CRS record for.
2. Multiple broker accounts across jurisdictions
If you hold accounts with a CySEC broker, an FCA broker, and a BaFin broker simultaneously, each broker reports independently to its own local authority (Cyprus, UK, Germany), and all three exchange with your country of tax residence. Your tax authority receives three separate CRS reports. If your filed return doesn’t reconcile with all three, any one can trigger an enquiry.
3. Dual residents: reported to both countries
If you are tax resident in two jurisdictions (e.g., you hold dual nationality with tax obligations in both), CRS reporting goes to both. The broker reports the same account to each jurisdiction. Both tax authorities expect to see the income on your return. Tax treaties determine which has primary taxing rights, but the reporting itself is parallel.
4. Self-certification not completed
If you never completed a CRS self-certification (common with pre-existing accounts at brokers that grandfathered old clients), the broker falls back to your address on file to determine tax residence. If your address is outdated, reporting goes to the wrong jurisdiction. Worse: if the broker cannot determine any jurisdiction, the account may be reported as undocumented to all potential jurisdictions.
5. Tax authority mismatch triggers automatic enquiry
CRS matching is increasingly automated. The comparison is typically: CRS gross proceeds figure vs declared capital gains on your return. A mismatch doesn’t mean you did anything wrong — gross proceeds and net gains are different numbers. But the automated system flags the difference, and you receive a letter requesting reconciliation. Knowing this in advance and being ready to explain the methodology prevents unnecessary anxiety and accelerates resolution.
6. Offshore broker in a non-CRS jurisdiction
Brokers registered in Belize, St Vincent and the Grenadines, Vanuatu, or the Marshall Islands are not CRS Reporting Financial Institutions. No automatic reporting occurs. However, this does not eliminate your tax obligation. If your tax authority issues a bilateral information request to one of these jurisdictions (possible under Tax Information Exchange Agreements, TIEAs), or if you are subject to a random audit, the undisclosed income surfaces with significantly harsher penalties than a simple filing error. Using a non-CRS broker to avoid reporting is a strategy with asymmetric downside.
How to Verify and Fix Your CRS Details
Six steps to ensure your broker’s CRS report matches your actual tax position. Do this annually, ideally in January before the broker compiles its report.
Log into your broker → Account Settings → Tax Residency
Find the section where your tax residence and TIN are stored. The exact location varies: eToro: Settings > Account > Personal Details; Interactive Brokers: Settings > Tax Information; XTB: Account > Personal Data; most CySEC brokers: Profile > Tax Information.
Verify your TIN
Cross-reference the TIN on file against your national tax portal or latest tax assessment notice. Common formats: Germany (11-digit Steuerliche Identifikationsnummer), France (13-digit Numéro fiscal), UK (10-digit UTR), Ireland (7-digit PPS + letter), Netherlands (9-digit BSN). A single transposed digit prevents automated matching.
Complete or update your self-certification form
If your broker offers a CRS self-certification form (the CRS equivalent of the W-8BEN), complete it with your current details. This is the primary document your broker relies on. Some brokers call it “Tax Residency Declaration” or “FATCA/CRS Declaration.” It typically asks: jurisdiction of tax residence, TIN, and confirmation of the information’s accuracy.
Update tax residency after relocation
If you moved countries, submit a new self-certification reflecting your new jurisdiction. The change takes effect for the next CRS reporting period. If you move in November 2025 and update your broker in December 2025, the 2025 report may still go to your old country (depending on the broker’s cut-off date). The 2026 report goes to the new country.
Request your CRS report from your broker (GDPR Art. 15)
Under GDPR Article 15 (right of access), you can request a copy of the CRS report your broker filed with the tax authority. Email your broker’s compliance or DPO address with a Subject Access Request specifying you want the CRS/AEOI report data filed for tax year [YEAR]. The broker has one calendar month to respond. This is the most reliable way to see exactly what your tax authority received.
Reconcile and flag discrepancies
Compare the CRS report against your own records: year-end balance, total income, gross proceeds. If any figure is wrong (e.g., the broker reported an incorrect year-end balance because of a currency conversion error), contact the broker’s compliance team and request a correction. Corrections are filed as amended CRS reports and take effect in the next reporting cycle.
CRS and Forex Relocators
Traders who have moved countries face the most complex CRS situations. The 183-day rule used in most tax treaties is irrelevant to CRS— CRS uses your self-certification and broker records, not a day count.
Exit Tax Considerations
Six European countries impose exit taxes on unrealised gains when you cease tax residency. CRS data does not directly trigger exit tax — but the CRS report confirming your account still exists after departure gives the old country evidence that unrealised gains were present at the time of exit.
| Country | Exit Tax Scope | Key Thresholds |
|---|---|---|
| Germany | Unrealised gains on shares >1% holding | Not applicable to forex/CFD positions directly; applies to company shares |
| France | Exit tax on unrealised gains, receivables, and certain income | >EUR 800,000 in securities or >50% of company profits |
| Norway | Unrealised gains on shares/fund units held >5 years | Deferred payment with guarantee required; lapses after 5 years in EEA |
| Spain | Exit tax on unrealised gains for departing tax residents | >EUR 4,000,000 in securities or >EUR 1,000,000 + >25% participation |
| Italy | Exit tax on unrealised capital gains (Art. 166 TUIR) | Applies to qualifying holdings; deferral available within EU/EEA |
| Denmark | Haemse-beskatning on unrealised share gains | DKK 100,000 exemption; mark-to-market already taxes forex CFDs annually |
Dual Reporting Year
If you move mid-year, both the old and new countries may receive CRS data for that year. The broker reports to whichever jurisdiction is on file at its reporting cut-off date. If you update your self-certification promptly, the report goes to the new country for the full year. If you update late, the old country receives the report and the new country does not — creating a gap that becomes visible when you file in the new country claiming income that their CRS records do not corroborate.
The 183-Day Rule Does Not Apply to CRS
Tax treaties use the 183-day rule to determine tax residency for treaty purposes. CRS does not. CRS reporting is driven by the self-certification you provide to your broker. If your self-certification says “Germany,” the broker reports to Germany — regardless of how many days you spent there. This is a common source of confusion for relocators who assume CRS tracks physical presence.
Common Relocator Trap
Scenario: you move from Germany to Portugal in March 2025. You update your Portuguese tax registration but forget to update your broker. The broker still has Germany on file. CRS data for 2025 goes to BZSt (Germany). You file a Portuguese return declaring the income. Portugal’s tax authority checks CRS records — no data from any broker. They may accept your self-declared figures, or they may query the discrepancy. Meanwhile, Germany receives CRS data for an account holder who filed no return. Both authorities are now asking questions. The fix is simple — update the broker — but the cost of not doing so is two parallel enquiries.

CRS vs FATCA: What European Forex Traders Need to Know
CRS is the OECD’s global standard. FATCA (Foreign Account Tax Compliance Act) is the US-specific predecessor. Both require financial institutions to report account holder data, but they differ in scope, thresholds, and who is targeted.
| Dimension | CRS | FATCA |
|---|---|---|
| Governing body | OECD | United States IRS |
| Adopted | 2014 (first exchanges 2017) | 2010 (enacted), 2014 (first reporting) |
| Participating jurisdictions | 100+ (all EU, UK, CH, Singapore, HK, etc.) | All jurisdictions with US IGA agreements (~113 IGA partners) |
| Who is reported | Tax residents of any participating jurisdiction | US persons (citizens, green card holders, substantial presence) |
| Reporting entity | Reporting Financial Institution (RFI) in each jurisdiction | Foreign Financial Institution (FFI) reporting to IRS |
| Self-certification form | CRS Self-Certification (varies by jurisdiction) | W-8BEN / W-8BEN-E / W-9 |
| Reporting basis | Tax residence of account holder | US indicia (citizenship, birthplace, address, phone) |
| Thresholds | Pre-existing individual <$250k: simplified due diligence (still reported) | Pre-existing individual <$50k: exempt from review (depository), <$250k simplified (custodial) |
| Exchange mechanism | Bilateral — jurisdiction A sends to jurisdiction B via Competent Authority Agreement | IGA Model 1: FFI reports to local authority, local authority sends to IRS. Model 2: FFI reports directly to IRS. |
| Applies to EU forex traders? | Yes — this is the primary reporting framework | Only if the trader is a US person or the broker has US operations |
If you are not a US person, FATCA does not apply to you directly. Your broker may still collect a W-8BEN form to confirm your non-US status. CRS is the framework that governs your reporting.
Decision Framework: CRS Complexity by Trader Profile
Not every trader faces the same CRS burden. Your complexity depends on how many brokers you use, whether you’ve moved countries, and your legal structure.
Single-Country, Single-Broker
LOWSimplest case. One broker reports to one tax authority. Your only action: verify your TIN and tax residency are correct on the broker’s records. Annual check in January. If the CRS data matches your return, no issues arise.
Multi-Broker, Single Country
MODERATEEach broker reports independently. Ensure all brokers have the same TIN and tax residency on file. Your tax authority receives multiple CRS reports — the sum must reconcile with your filed return. Consolidating to fewer brokers reduces friction, but is not strictly necessary if records are consistent.
Relocator / Expat
HIGHHigh complexity. You must update every broker’s self-certification to the new jurisdiction. Check for dual-year reporting obligations. Review exit tax provisions in your departure country. Expect both old and new tax authorities to hold CRS data for the transition year. Keep certificates of tax residency from both jurisdictions as evidence.
Corporate Trader (OÜ / SIA / UAB)
HIGHEntity CRS rules apply. Your trading company is likely a Passive NFE, meaning the broker reports both the entity account data andthe personal details of controlling persons (>25% shareholders). If you are the sole shareholder, your personal CRS data is reported alongside the company account. Ensure the company’s self-certification correctly identifies the entity type and all controlling persons.
Digital Nomad Without Fixed Tax Residency
HIGHESTMaximum CRS risk. If you have no fixed tax residency but your broker has an address on file, the broker reports to the jurisdiction of that address. This may not match your actual tax obligations. If the address jurisdiction queries you and you claim non-residency, you need to demonstrate where you aretax resident — which may be nowhere, or everywhere, depending on the treaties and domestic rules involved. CRS does not accommodate statelessness gracefully. The pragmatic solution is to establish and maintain formal tax residency in one jurisdiction, update your broker accordingly, and file there.
