The DITC no longer provides an XML generator tool, and from early 2027 every new return, correction and deletion must be in the OECD’s v3.0 schema. AEOIkit is a browser-based generator that produces it, validated, with a workflow you already know. If the DITC’s rules require changes once the portal reopens, every licensed copy gets the update free.

It does one job — producing a schema-valid v3.0 CRS XML file — and is priced like a tool, not a platform.
Output validates against the OECD v3.0 schema set, including the new account-type, joint-account and self-certification data.
The core tool runs entirely in your browser. Entry, CSV import, validation and XML generation happen on your machine — no upload, no server, and it works offline.
The same tab layout and identifier conventions as the retired DITC tool, plus plain-language error lists, CSV bulk import and draft save/load.
CI$1,500 (charged as US$1,800) per FI, per reporting year, as a one-off purchase — about the cost of outsourcing one filing — with volume rates for administrators, TCSPs and director firms.
The DITC’s free XML generator is gone, the portal is expected to reopen in early 2027 for v3.0 files, and the 2026-period deadline is 30 June 2027.
With the move to v3.0, the DITC is no longer providing an XML generator tool.
New reportable accounts, corrections and deletions must all be submitted in XML Schema v3.0 — including corrections to returns for earlier years.
The 2026-period deadline, a month earlier than the old 31 July. The portal is expected to reopen in early 2027.
2025-period deadline — last cycle under the old schema.

Four steps, all on your machine.
Open your licensed copy in the browser you already use. No installer, no account, and no connection needed once it’s open.
Key in accounts using the familiar tabs, or bulk-import from CSV. Save a draft and resume later — drafts stay on your machine.
One click runs schema rules, v3.0 data-quality rules and DITC identifier conventions, and lists anything to fix in plain language.
Download the validated XML and upload it to the DITC portal. The product video shows every step on sample data.
Private trust companies, standalone funds, captive insurers, family-office vehicles — anyone whose compliance officer or director used the free DITC tool.
Per-FI licensing that scales: from CI$8,000 per reporting year for 10 FIs, sliding to about CI$300 per FI at 51+ FIs.
CARF support is planned for 2027, and FATCA is under consideration. Tell us what you file and where, and we’ll write when it’s ready — nothing else.
A two-minute video on sample data: entry, spreadsheet import, the plain-language error list, a correction and the finished v3.0 file. Questions after watching? Email us and we’ll answer within one business day.
What changed in the OECD standard, what it means for the file you submit, and how AEOIkit checks it. This page applies wherever the amended standard is adopted; the jurisdiction pages cover local rules and dates.
The OECD amended the Common Reporting Standard and published a new XML schema, version 3.0, with a user guide for tax administrations (version 4.0, 2024). Jurisdictions adopting the amended standard require returns in the new schema.
For a reporting FI the practical change is more data per account. The v3.0 schema adds elements such as the account type, whether an account is new or preexisting, joint-account details and the number of joint holders, the role behind an equity interest, and whether a valid self-certification is held.
New elements bring new data-quality rules, and receiving jurisdictions validate against them. A file can be well-formed XML and still be rejected. That is why AEOIkit validates twice: against the OECD schema, and against the business rules the status-message guidance describes.
The user guide sets out how corrections and deletions work: a corrected record references the record it replaces, and each correction completely replaces the earlier one. AEOIkit generates correction and deletion records using identifiers consistent with your prior filings.

Local deadlines, portals and identifier conventions differ. Start with yours.
What the DITC has announced, the dates that matter, and what you need to have in place before the portal reopens.
In one line: the DITC’s free XML generator is gone, the portal is expected to reopen in early 2027 for v3.0 files, and the 2026-period deadline is 30 June 2027.
Deadline for 2025-period CRS XMLs and Filing Declarations — the last cycle under the old schema.
The DITC Portal closes for CRS XML and Filing Declaration submissions.
The portal is expected to reopen for the 2026 reporting year, accepting XML Schema v3.0.
Deadline for the 2026 reporting period — a month earlier than the previous 31 July. From the 2026 reporting year onwards (first due 30 June 2027), the CRS return and the CRS compliance form are both due by 30 June.
Deadline for the 2027 reporting period.
With the transition to v3.0 the DITC is no longer providing an XML generator tool. Filers who relied on it need another way to produce a compliant file. AEOIkit keeps the same tab structure and identifier conventions, so the switch is a short one.
The DITC has said that any new reportable accounts, corrections or deletions must be submitted using XML Schema v3.0. If you need to correct or add to a return for an earlier period after the portal reopens, that file must be v3.0 as well. AEOIkit produces v3.0 new, correction and deletion records.
Existing FIs have until 31 January 2027 to complete the Principal Point of Contact appointment. Failure to file returns or keep PPoC details current can attract penalties per breach under the amended CRS Regulations.

The product, your data, licensing and support.
No. The core tool runs entirely inside your browser. Entry, CSV import, validation and XML generation happen on your machine — there is no server and no account, and you can run it offline.
Yes. It needs only a modern browser — Chrome, Edge, Firefox or Safari — on Windows, macOS, Linux or a tablet. No installer, no admin rights, no macros.
Yes. The two-minute product video runs the full workflow on sample data, from a blank return to a validated v3.0 file. Anything it doesn’t answer, email [email protected] and we’ll reply within one business day. We don’t send out trial copies of the tool.
A licence is a personalised, signed copy keyed to your organisation, FI number(s) and reporting year. Pay by card and it is emailed to you as a download link as soon as payment completes. CI$1,500 for one FI, CI$750 for each additional FI, intermediary licences from CI$8,000 for 10 FIs.
Nothing ends: your copy keeps working for returns up to its licensed year, including corrections. When the next year’s return can be prepared, we email you (around mid-November, again in mid-January, and a last time in April) with a link that has your details filled in. Renewal is a deliberate purchase, not an auto-charged subscription.

An independent, Cayman-based team who have prepared and filed CRS returns through the DITC portal. It is deliberately a focused tool: it produces schema-valid v3.0 CRS XML and is priced accordingly.
The OECD standard, wherever you file.
The OECD’s XML schema for the amended Common Reporting Standard. It adds data per account — account type, new or preexisting, joint-account details, equity-interest role, self-certification status — and brings new data-quality rules with it. More on the CRS v3.0 page.
No. The 50-account cap some filers remember came from the tool’s origins, not the schema. AEOIkit is tested with 1,000-account returns.
Yes. AEOIkit produces v3.0 correction and deletion records that reference the records they replace, with identifiers consistent with your prior filings.
The current release implements Cayman conventions. The Isle of Man, Guernsey and Jersey are planned for 2027, each validated against local rules before release. Tell us where you file and we’ll let you know.
Yes. Support for the Crypto-Asset Reporting Framework is planned for 2027. In the Cayman Islands the CARF rules took effect on 1 January 2026, and the first returns, for 2026, are due by 30 June 2027. FATCA is under consideration. If you’ll report under either, tell us at [email protected] and we’ll write when it’s ready.
DITC-specific answers. The dates are on the Cayman guide.
No. AEOIkit is not endorsed or approved by the DITC or any other body. What we can say is that AEOIkit’s output validates against the official OECD v3.0 schema with zero errors on our test returns, and that when the DITC publishes its v3.0 portal rules we will re-validate against them and publish the results.
With the move to v3.0, the DITC is no longer providing an XML generator tool. The portal closed to CRS XML in early August 2026 and is expected to reopen in early 2027 for v3.0 files.
Yes. The DITC has said new reportable accounts, corrections and deletions must be submitted in XML Schema v3.0 — so a correction to a prior period filed after the portal reopens must be v3.0 too.
30 June 2027, a month earlier than the old 31 July. From the 2026 reporting year onwards, the CRS return and the compliance form are both due by 30 June each year.
Yes. MessageRefId and DocRefId follow the DITC identifier conventions used by the retired DITC tool. A correction references the DocRefId of the record you originally filed.

A licence is a personalised, signed copy of the AEOIkit tool. It is keyed to the organisation name, the FI number(s) and the last reporting year you gave us when you ordered. It generates returns only for those FI numbers and for reporting periods up to that year. Please check those details before you pay: the copy is locked to them.
We deliver your copy by email as a download link. The link works for 30 days and 5 downloads. If it expires or you lose the file, get a new link from Your licences on this site (we email a one-time sign-in link to the address you ordered with), or email us and we will re-issue it.
