Is the Elcano compliance report legally binding?

No. The report is not a legal instrument and does not constitute legal or tax advice. It is a structured documentation of self-reported travel data, formatted to give your tax advisor a clear, auditable record of your movements. The SHA-256 hash and report ID allow advisors to verify the document has not been modified after generation. Whether the document satisfies a specific authority's evidence requirements depends on that authority's standards; consult a qualified tax advisor for your jurisdiction.

What types of evidence files can I attach?

You can attach PDFs and images to each trip: boarding passes, hotel bookings, Airbnb confirmations, rental agreements, utility bills, bank statements showing domestic transactions, and any other document that substantiates your physical presence in or absence from a country. The Evidence Index section lists all attached files by trip, and Appendix B reproduces the actual documents in the PDF. Files are stored locally on your device and are not uploaded to any server.

Does Advisor Mode change the travel data in the report?

No. Advisor Mode does not modify your travel records. It adds four things to the standard report: a Table of Contents, a Methodology Statement explaining the counting rules and data source, a SHA-256 hash of the underlying data so the report can be verified against the source, and a Report ID embedded as a watermark on every page. All underlying travel entries, day counts, and risk assessments are identical to the standard report.

Tax Residency Compliance Report

Q: Can I share this report with HMRC, AEAT, or another tax authority?

Yes, you can share it as supporting documentation. The report is formatted as a formal PDF with a methodology statement explaining how days are counted, six signed data integrity declarations, and a complete daily log. It is structured to accompany a tax filing or advisory engagement, not replace one. Most tax authorities accept self-reported travel records as supporting evidence; the key is that the methodology is explicit and the data is internally consistent, which the validation checks in the report confirm.

Updated May 2026 · 12-section PDF · SHA-256 data integrity

Most tools that generate “tax residency proof” produce a spreadsheet or a screenshot. The Elcano compliance report is a structured PDF document with a formal methodology statement, an evidence index, and six signed data integrity declarations — the kind of document a tax advisor can review alongside the rest of your filing without having to question its provenance.

The standard report covers your travel record for a calendar year: days per country, residency risk per threshold, trip timeline, and a complete daily log. Advisor Mode adds a Table of Contents, a Methodology Statement, and a SHA-256 hash embedded as a page watermark, making the document verifiable after the fact.

What the report contains

Sections 1–2 are standard. Sections 3–12 appear in Advisor Mode (sections 11–12 are appendices).

1

Cover Page

Year, total days logged, number of countries, generation timestamp. In Advisor Mode: Report ID, ISO generation datetime, SHA-256 hash, and the “Prepared for” identifier.
2

Table of Contents Advisor Mode

Auto-generated index of all sections with page numbers, filled after pagination is complete.
3

Methodology Statement Advisor Mode

Four declarations: how days are counted (calendar day, midnight to midnight), data source (manual entry, no GPS), threshold data (internal rules database, country-specific), and how future-dated entries are handled.
4

Executive Summary

Days tracked, countries with recorded presence, unassigned days. Data validation results: duplicate dates, overlapping country assignments, and invalid date ranges, with pass/fail status for each check.
5

Travel Context

Trip streaks grouped by country — consecutive runs of days in each place, with start date, end date, and length. Gives advisors a readable itinerary rather than a raw date table.
6

Country Comparison

Proportional bar showing all tracked countries as segments of the year, with the 183-day marker indicated. Per-country table: days, percentage of year, risk level.
7

Risk Overview

Residency risk status for each country (Safe / Caution / High) against the applicable threshold. Countries with no recorded presence are excluded.
8

Timeline

Chronological sequence of trips with evidence coverage indicators. Each stay shows whether supporting documents have been attached.
9

Evidence Index

Table of all documents attached to each trip: filename, stay dates, and country. Gives advisors a structured reference list before they look at the actual files in the appendix.
10

Data Integrity

Six signed declarations on data source, storage, import policy, user responsibility, evidence handling, and legal scope. See the full text below.
11

Appendix A — Daily Log

Complete date-by-date table of every entry for the year. Each row: date, country. Used by advisors to cross-check specific dates independently.
12

Appendix B — Evidence Files

Reproductions of all uploaded documents — boarding passes, booking confirmations, bank statements, and similar. Included automatically when evidence files are attached to trips.

What Advisor Mode adds

Advisor Mode does not change your travel data. It adds verification infrastructure and a formal methodology statement, making the document auditable after generation.

Report ID

A unique identifier (e.g., RD-M0F3X2A) assigned at generation time. Embedded on the cover and in the watermark on every subsequent page. Advisors can request a specific report by ID if they need to verify which version they received.

⋮

SHA-256 Data Hash

A cryptographic hash of the underlying travel data (year, all dated entries, and country assignments). If the document is modified after generation, the hash will not match the source data. Every page carries the hash in its footer watermark:

RD-M0F3X2A • 2026-05-19T10:32:15.000Z • SHA-256 a3f9c1e8d2b47f6e...

☰

Table of Contents

Auto-generated section index with page numbers, inserted on page 2. Page numbers are resolved after the full document is paginated, so they are always accurate regardless of how many trips or evidence files are present.

“Prepared for” field

An optional identifier (typically your email address or your advisor’s firm name) shown on the cover page. Useful when sharing the report with a specific advisor or for a specific engagement.

Evidence you can attach

Each trip in Elcano can have one or more supporting documents. They are stored locally on your device and reproduced in Appendix B when you export. The most commonly useful types:

Boarding passes Hotel bookings Airbnb confirmations Rental agreements Utility bills Bank statements Train & ferry tickets Insurance documents Passport scans Work contracts

Evidence does not have to be exhaustive to be useful. An advisor reviewing your position needs enough documentation to establish a credible pattern of presence — not a receipt for every day. Boarding passes for entries and exits, combined with accommodation bookings for multi-week stays, are typically sufficient for most jurisdictions.

Six data integrity declarations

The Data Integrity section of the report contains the following statements, identical across all languages:

Data source

This report is generated automatically from user-recorded travel logs. All presence data is entered manually by the user.
Data storage

When signed in to an account, presence records are stored securely in the cloud and synced across devices. When used without an account, records are stored locally on the device only.
No automatic import

No third-party travel history data is automatically imported. This report reflects only what the user has explicitly recorded.
User responsibility

Users are responsible for verifying the accuracy of recorded travel dates. This tool does not independently verify travel data.
Evidence files

Evidence files are stored locally and referenced by filename. They are not altered by the application.
Legal disclaimer

This report does not constitute legal or tax advice. A qualified tax advisor should be consulted.

Frequently asked questions

Is this report legally binding?

No. The report is not a legal instrument and does not constitute legal or tax advice. It is structured documentation of self-reported travel data, formatted to give your tax advisor a clear, auditable record of your movements. The SHA-256 hash and Report ID allow advisors to confirm the document has not been modified after generation. Whether it satisfies a specific authority’s evidence requirements depends on that authority; consult a qualified advisor for your jurisdiction.

Can I share this with HMRC, the AEAT, or another tax authority?

Yes, as supporting documentation. The report is formatted as a formal PDF with an explicit methodology statement, six signed integrity declarations, and a complete daily log. It is intended to accompany a tax filing or advisory engagement, not replace one. Tax authorities routinely accept self-reported travel records as supporting evidence; the key is that the methodology is stated explicitly and the data is internally consistent, both of which the report’s validation checks confirm.

What file types can I attach as evidence?

PDFs and images (JPEG, PNG). The application accepts any file you can view on your device. Common formats that advisors find most useful: PDF boarding passes, JPEG hotel booking confirmations, PNG screenshots of calendar bookings, and scanned passport entry stamps. Files are stored locally and are never uploaded to any server.

Does Advisor Mode change my travel data?

No. Advisor Mode adds verification infrastructure — Report ID, SHA-256 hash, Table of Contents, Methodology Statement — without touching the underlying travel entries. Day counts, risk assessments, and trip sequences are identical between standard and Advisor Mode exports of the same data.
