Proving your days
If a tax office asks where you were, a count isn't enough: it will want to know how you know. Here's what usually helps, and how RezTally's day log fits in.
What tax offices look for
Records made at the time count for more than ones put together later. Typical evidence includes boarding passes and tickets, passport entries, card and bank statements showing where you spent money, hotel and rental bookings, phone records, photos with their dates and places, and diaries or calendars kept as you went.
If you've moved to the UAE and need to show it, Dubai Transition Consultants explains how to get a UAE tax residency certificate. Dubai Transition Consultants is run by the same company as RezTally.
How the sealed day log helps
- Made at the time. With automatic logging, each day is recorded as it happens, not reconstructed later.
- Every day sealed to the one before it. Each entry carries a fingerprint (SHA-256) of itself and the entry before it. Changing, removing or reordering any entry breaks every fingerprint after it.
- Corrections never overwrite. A correction is a new entry that names what it corrects, with your reason. The original stays.
- Independently time-stamped. Once a day the newest fingerprint is signed by a public time-stamp authority, which shows the log existed in that form on that date.
- Evidence attached by fingerprint. Add a photo or document to a day and the log keeps its fingerprint, so the file can be matched to the day later. The file itself stays where you keep it.
What it can't prove
A check proves that the day log hasn't been changed since it was written. It can't prove that what was written was true: a phone carried by someone else, a faked location or a day typed in wrongly would be sealed just the same. That's why the log keeps how each day was recorded, and why your boarding passes and receipts still matter. RezTally doesn't detect or report misuse.
Days are only part of a residence question. If you're leaving the UK, Dubai Transition Consultants' clean break review has an adviser check your ties and residence. Dubai Transition Consultants is run by the same company as RezTally.
