The Fund Annual Return deadline — 30 June for December year-end funds — is one of the most operationally demanding dates in the Cayman fund compliance calendar. But it is far from the only one. A registered Cayman fund faces a series of annual obligations across multiple regulators, each with its own deadline, its own data requirements, and its own penalty regime.
Missing any one of them can leave a fund out of good standing, expose its operators to regulatory sanction, and create complications that outlast the missed deadline by years. This post maps the full annual compliance calendar so that fund operators and their service providers can see every obligation in one place — and plan accordingly.
The FAR: The Anchor Obligation
Everything in the Cayman compliance calendar is organised around the FAR because it is the most data-intensive and time-consuming obligation, and because the audit it depends on sets the pace for much of what follows.
Deadline: 30 June (for December year-end funds); six months after year-end for all others
Filed with: CIMA via REEFS
What it requires: Completed FAR form (Excel), audited annual financial statements, operator declaration (private funds), and filing fee
Consequence of missing it: Serious or very serious breach under CIMA's Administrative Fines Regime; fund loses good standing; cannot deregister until resolved
The FAR is the obligation that requires the longest lead time — preparation should begin in January, running in parallel with the audit process. Every other deadline in this calendar sits downstream of getting the FAR right.
FATCA Reporting: US Investor Disclosure
Deadline: 31 July (for the prior calendar year)
Filed with: Cayman Department for International Tax Cooperation (DITC) via the DITC Portal
What it requires: Account-level reporting of US person investors (names, account balances, tax identification numbers) to the DITC, which passes the data to the US Internal Revenue Service. Funds with no US person investors must file a nil return confirming that status.
How it relates to the FAR: FATCA requires individual-level investor data; the FAR requires only aggregate investor jurisdiction data. FATCA reporting does not satisfy the FAR and vice versa — they are separate obligations with separate regulators.
CRS Reporting: Global Investor Disclosure
Deadline: 31 July for the current reporting cycle (note: from 2027 onwards, under the amended CRS Regulations effective 1 January 2026, the CRS deadline moves to 30 June — aligning it with the FAR for the first time)
Filed with: DITC via the DITC Portal
What it requires: Account-level reporting of investors who are tax residents of any of the 100+ CRS participating jurisdictions. Broader in scope than FATCA — most Cayman funds will have CRS reportable accounts. A CRS Compliance Form must also be filed annually (deadline: 15 September), covering the fund's CRS compliance policies and procedures.
How it relates to the FAR: The investor jurisdiction data gathered for CRS due diligence is the same underlying data that informs the FAR's investor section — but at different levels of granularity. CRS data is individual-level; the FAR uses aggregates. Neither satisfies the other.
Economic Substance Filing
Deadline: 12 months after the end of the relevant financial year (i.e. 31 December for December year-end entities)
Filed with: Cayman Islands Department for International Tax Cooperation (DITC) via the DITC Portal
What it requires: Cayman entities that conduct relevant activities (which for most funds means holding company or investment fund business) must file an economic substance notification and, where applicable, an economic substance report. Registered investment funds are generally exempt from the substance test itself but must still file a notification confirming their exempt status.
How it relates to the FAR: The economic substance filing and the FAR are entirely separate obligations filed with different regulators. However, the entity classification and activity information required for the economic substance notification draws on the same underlying information about the fund's structure and operations that is captured in the FAR.
Beneficial Ownership Filing
Deadline: Ongoing — updates required within 15 days of any change; annual confirmation required
Filed with: The fund's registered office in the Cayman Islands, which maintains the beneficial ownership register on behalf of the competent authority
What it requires: Cayman funds must maintain a beneficial ownership register identifying all beneficial owners (natural persons who ultimately own or control 25% or more of the fund's interests, or who exercise ultimate effective control). The register is not public but must be kept current and filed with the competent authority.
How it relates to the FAR: The beneficial ownership register and the FAR capture overlapping but different investor data. The FAR records aggregate investor information; the beneficial ownership register captures specific identifying information about qualifying individuals. Neither filing satisfies the other.
Annual General Meeting and Corporate Filings
Deadline: Varies by fund structure and constitutional documents
Filed with: Cayman Islands General Registry (for companies); relevant registered office
What it requires: Cayman exempted companies must file an annual return with the Registrar of Companies confirming basic corporate information and paying the annual government fee. The annual government fee for exempted companies is due by 31 January each year. Failure to pay triggers a 33% surcharge.
How it relates to the FAR: The annual Registrar filing and government fee are entirely separate from the CIMA FAR. A fund that has paid its Registrar fee and filed its corporate return has not satisfied its CIMA obligations — and vice versa.
Putting the Calendar Together
For a December year-end fund, the annual compliance calendar looks like this:
Deadline | Obligation | Regulator |
31 January | Annual government fee (exempted companies) | Cayman General Registry |
30 June | FAR + audited accounts + filing fee | CIMA via REEFS |
31 July | FATCA report / nil return | DITC |
31 July | CRS report (moving to 30 June from 2027) | DITC |
15 September | CRS Compliance Form | DITC |
31 December | Economic substance notification / report | DITC |
Within 15 days of change | Beneficial ownership register update | Registered office / competent authority |
Every deadline on this calendar has consequences for missing it. But the FAR is the one that takes the longest to prepare, depends on the most moving parts, and sets the tone for everything that follows. A rejected submission in late June is not just a FAR problem — it is a compliance year problem.
CIMA's REEFS system validates every FAR automatically on upload. Missing fields, invalid drop-down selections, financial data that doesn't reconcile, deprecated classification codes — any of these will trigger an automatic rejection with no human review. By the time you find out, the clock is still running.
Validation before submission means running the completed form through a systematic check of every field, every selection, and every data point before it reaches REEFS. You can spend hours manually validating each FAR file or use a validator to identify cells that REEFS is likely to flag as errors.
