Annex IV Reporting: AIFMD Filings, Deadlines, and 2026 Changes

Annex IV reporting is the standardized disclosure that Alternative Investment Fund Managers file with their national competent authority under Article 24 of the Alternative Investment Fund Managers Directive (AIFMD), covering portfolio exposures, leverage, liquidity, and risk data for each fund they run or market in the European Union. The obligation applies to hedge fund, private equity, real estate, and other non-retail fund managers, and it is expanding on 16 April 2026 when AIFMD 2.0 takes effect.¹

Who Has to File

Any entity classified as an AIFM owes Annex IV to the competent authority of its home member state. That covers managers based anywhere in the European Economic Area that run hedge funds, private equity funds, real estate funds, or other non-retail vehicles, and it reaches every EU AIF the manager operates plus every non-EU AIF it markets to European investors.²

p>Non-EU managers are pulled in too. A U.S. or other non-European firm that markets a fund to professional investors in Europe through a National Private Placement Regime (NPPR) under Article 42 takes on reporting and disclosure obligations for those funds. Physical location does not matter; access to European capital does.

Full-Scope Versus Sub-Threshold

The directive splits managers into two categories with very different burdens. Full-scope AIFMs report the complete regime under Articles 24(1), 24(2), and where applicable 24(4), reaching individual instrument exposures and stress test results. Sub-threshold (or “registered”) managers report a lighter package under Article 3(3)(d): AIFM-level information plus high-level AIF data such as main instruments traded, principal exposures, and most important concentrations.³

The dividing line is €100 million in assets under management for managers whose funds use leverage, or €500 million for managers whose funds are entirely unleveraged. Stay below and you are sub-threshold. Cross either figure and you are full-scope, with a much heavier reporting load.⁴ Threshold calculations must include assets acquired through leverage, not just net asset value, and the AIFMD definition of leverage is broad enough to capture leverage embedded in derivative positions as well as traditional borrowing.

How Often You File, and By When

Reporting frequency depends on three variables: total AUM, whether the funds use leverage, and the type of fund. A single manager may end up filing different funds on different cycles.

Quarterly: non-PE funds with AUM above €500 million, and leveraged AIFs where the manager’s total AUM exceeds the registration threshold. Funds using substantial leverage report additional data under Article 24(4).
Semi-annual: funds with AUM below €500 million, including leveraged AIFs under that ceiling.
Annual: unleveraged private equity funds focused on acquiring control of non-listed companies, regardless of size; sub-threshold managers also file annually under the lighter regime.

Managers with AUM above €1 billion face the most intensive quarterly obligations. Sitting near a threshold means monitoring AUM carefully, because crossing the boundary mid-year shifts your frequency for the next period.⁴

Filings are due 30 or 45 days after the end of each reporting period, with the exact window set by the national competent authority. Quarterly filers work from 31 March, 30 June, 30 September, and 31 December. Semi-annual filers work from 30 June and 31 December. Annual filers work from 31 December. Fund-of-funds managers get an additional 14 days beyond the standard deadline to reflect the practical difficulty of aggregating data from underlying funds. Confirm which window (30 or 45 days) your NCA applies before you build your calendar.

One date to mark for 2026: manual Annex IV submissions will be discontinued starting 1 June 2026, and from the 30 June 2026 reporting reference date onward, all reports (and any corrections to prior filings) must be submitted in XML.

What Goes Into the Report

The filing has two layers: AIFM-level information about the manager’s overall business, and AIF-level information for each individual fund.

AIFM Level

At the manager level, the report captures identifying details (legal name, LEI or other identification codes, jurisdiction), total AUM across all reported funds in euros, and a ranking of the top five markets and top five instrument types by aggregated value.³

AIF Level

Each fund requires its own profile:

Fund identification: legal name, ISIN or other codes, LEI, inception date, domicile, base currency, NAV, total AUM, and any prime brokers.
Investment strategy: the predominant fund type (hedge fund, private equity, real estate, fund of funds, or other) and a percentage breakdown of NAV by strategy.
Principal exposures: the five most important individual instruments, the ten principal exposures by sub-asset type, and the five most important portfolio concentrations by asset type and market, each flagged long or short.
Investor concentration: the five beneficial owners with the largest equity interests and a split between retail and professional investors.
Geographical focus: where investments are domiciled and the three main funding sources by jurisdiction.

Full-scope managers filing under Article 24(2) go further, reporting instrument-level exposures across a taxonomy of sub-asset types running from listed equities and sovereign bonds through credit default swaps and real estate, alongside turnover (total buys and sells) per asset class and currency exposure broken into long and short values.²

Leverage

Managers running funds that employ leverage on a substantial basis face additional reporting under Article 24(4): the overall level of leverage for each fund, split between leverage from borrowing cash or securities and leverage embedded in financial derivatives, plus the identity of the five largest sources of borrowed cash or securities and the amounts received from each.² Leverage must be calculated using both the gross method (Article 7 of Delegated Regulation 231/2013) and the commitment method (Article 8), and both figures reported.⁵

Liquidity and Stress Testing

The liquidity section forces a side-by-side comparison. For the portfolio profile, each investment goes into exactly one time bucket based on the shortest period within which it could reasonably be liquidated at or near carrying value; the buckets must total 100%. For the investor profile, NAV is divided among time buckets based on the shortest period within which investors could withdraw, assuming the manager would impose gates where allowed but would not suspend redemptions entirely.³ The comparison surfaces mismatches: a fund whose assets take six months to sell but offers monthly redemptions is the pattern regulators are looking for.

Stress test results round out the section. Managers report outcomes from market risk stress tests under Article 15(3)(b) and liquidity risk stress tests under Article 16(1). Closed-ended unleveraged AIFs are exempt from conducting liquidity stress tests, but the field still needs a response indicating the question is not applicable and noting the fund’s structure.

How You Submit It

Annex IV reports must be submitted electronically in XML format. No other format is accepted.⁶ The file must conform to ESMA’s XSD schema (currently Version 1.2), and ESMA’s IT technical guidance provides XML samples, validation rules, and geographic reference tables for building compliant files.⁷

Submission runs through the digital portal of whichever NCA oversees the manager or the jurisdiction where the fund is marketed. In Germany, for example, XML files must be submitted through BaFin’s MVP reporting portal, and no other transmission method is permitted.⁸ Other NCAs run their own portals along similar lines.

On upload, the regulator’s system checks the file against the XSD schema to confirm the structure is valid and no mandatory fields are missing or misformatted. Revision 6 of the technical guidance tightened those validation rules, making more fields mandatory.⁷ A file that fails validation is rejected with an error message. If data passes technical checks but looks inconsistent with prior filings or market norms, the regulator can request a correction or resubmission.⁶

Most managers use compliance software or third-party consultants to map internal portfolio data onto the XML structure. The report contains hundreds of fields with specific formatting expectations, and a mismatch between your internal classification of an instrument and ESMA’s sub-asset taxonomy will trigger a validation failure. Getting the data pipeline right the first time is cheaper than debugging rejections against a deadline.

What Changes on 16 April 2026

Directive 2024/927, known as AIFMD 2.0, requires member states to transpose its provisions into national law by 16 April 2026.¹ Enhanced Annex IV reporting content goes live that day, so managers need to provide more granular data in their first filing period after implementation. The fully refreshed XML templates arrive a year later: ESMA’s new regulatory and implementing technical standards reshaping the templates are due by 16 April 2027.

Notable additions:

Delegation data: the revised templates will capture how fund management functions are delegated.
Fee and expense disclosure: managers must annually provide investors with a complete list of all fees, charges, and expenses borne directly or indirectly by investors, plus disclosure of any parent undertaking, subsidiary, or special purpose vehicle used in connection with the fund’s investments.
Loan-originating AIFs: new rules for open-ended loan-originating funds introduce specific liquidity management requirements and stress testing obligations effective 16 April 2026.⁹
Non-EU manager scope: the enhanced reporting reaches non-EU AIFMs marketing funds in the EU, not only EU-domiciled managers.

The gap between April 2026 and April 2027 is where trouble concentrates. Managers must supply the new content in 2026, but the standardized templates that make filing routine do not arrive until 2027. The first year of enhanced reporting may run on manual processes or interim formats issued at national level.

AIFMD 2.0 also tightens eligibility for non-EU managers marketing under Article 42: neither the manager nor the fund can be domiciled in a country on the EU’s anti-money laundering blacklist or the list of non-cooperative tax jurisdictions, and the manager’s home country must have a signed OECD Model Tax Convention with the marketing country. Slipping out of compliance on any of these can independently block access to European investors.

What Happens If You Miss or Fail a Filing

Sanctions vary widely because each member state runs its own administrative sanctions regime; there is no single EU-wide fine schedule. In 2022, ten NCAs imposed a combined 128 penalties totaling more than €2 million, including one penalty of €1,520,000 from a single NCA.¹⁰

Non-financial measures matter as much as fines. Regulators can issue formal warnings, attach conditions to marketing authorizations, or revoke permission to market funds within the jurisdiction. For a non-EU manager relying on an NPPR to reach European capital, losing that marketing route effectively shuts down European fundraising. Persistent late filings or data quality problems also tend to attract heightened scrutiny of future submissions, and the ongoing staff time and consultant fees often cost more than the original penalty.
