How to keep notes that hold up
Write notes as soon as you can. Keep the original account rather than replacing it later; the venue decides what weight it gets.
- Write it down straight away, on paper or in the box on a step.
- Put the date, time and place at the top, and who you spoke to.
- Use their words where you can; separate what you saw from what you were told.
- Sign or initial a paper note, photograph it and add the photo.
- Never edit an old note. Add a new dated entry when something changes. A device save time is not independent time evidence or proof of event order.

Receipts should show the work purpose too
Taxpayers sought tax relief for entertainment and other work costs. Some receipts showed where money was spent but not why or who attended. The court rejected those costs but allowed a few other work expenses.
Tax court decision with mixed expense findings; it also addressed a separate building-loss issue.

Expense dates can test a worker's explanation
A worker listed ski-weekend costs as a work trip elsewhere and blamed an app's default city. The court weighed a dated hotel booking and the worker's account. It kept the employer's win on the worker's claim of payback at work.

Past expense approval does not settle unfair firing
A manager was fired after an expense review, though her boss had approved earlier bills. She pointed to co-workers who had also claimed costs. The court said they were not in the same position and ruled for the employer on all claims.

Positions below refer to the cited rule or record type, not endorsement of Timevolt. This service is not represented as an eIDAS qualified timestamp provider. A non-qualified timestamp does not receive the qualified timestamp presumption.
IRS Publication 463, Chapter 5 Recordkeeping
Adequate records: an account book, diary, log or statement of expense plus documentary evidence such as receipts. Receipts are generally required for lodging and for any other expense of $75 or more. A computer-prepared record counts. A record made close to the time of the expense is worth more than one prepared later. If records are lost for reasons beyond your control (fire, flood), you may reconstruct them. With incomplete records you must back the missing element with your own detailed statement plus supporting evidence.
Selected expense-substantiation provisions only; this is not a complete summary of Publication 463. A time receipt dates exact file bytes. It does not establish contemporaneous expense entries or satisfy IRS substantiation requirements.

Read the source26 CFR 1.62-2 (accountable plans for employee reimbursements)
Expenses must be substantiated to the payor. Safe harbor: substantiation within 60 days after the expense is paid or incurred, and return of any excess within 120 days. Other periods are judged by facts and circumstances.
The 60-day clock makes a date on your receipt files directly useful, but the regulation requires substantiation to the employer, not a third-party timestamp. Employer policy sets the format.

Proves / Doesn’t prove
Proves
A completed time receipt shows that the exact selected file existed by the independently witnessed time. You can check whether a later copy has the same bytes. It does not establish creation time, authorship, identity, event order, location or the truth of the contents.
Doesn’t prove
It does not prove who made or paid for the receipt, that the purchase happened or was business related, that the amounts are true, or that an employer, the IRS or a tribunal will accept it.
This cannot establish a genuine purchase, business purpose, payment, true amounts or reimbursement.
These are the bounds of a completed proof. The local tester does not establish any time. The chosen court, scheme or regulator decides what to accept.
Questions, answered plainly.
Your file stays on your device. During normal receipt creation, your device sends a randomized code made from its fingerprint, plus encrypted recovery data. It doesn't send the plain fingerprint or the random value that opens the code. Keep the original file and the complete receipt for checking. Privacy Policy.
Do I need the original paper receipt, or is a photo enough?
The IRS says a computer-prepared record is acceptable, and a scanned or photographed receipt is commonly used. Your employer's expense policy decides what they accept, so check it. A time receipt can show the photo existed unchanged by a date.
