If you keep a mileage log, you have probably been told two things that can feel contradictory:
- Keep a contemporaneous record — write it down as the trip happens, not from memory months later.
- Keep your receipts — fuel, parking, tolls, client meals.
The second one is usually framed as expense substantiation: the dollars on the receipt support the dollars you deduct. But receipts do something else, too — something less obvious and more valuable when an auditor is on the other side of the desk. A receipt is a third-party record of where you were and when. A handwritten log entry is not.
That distinction is why RoadStance describes a receipt-backed trip differently from a trip transcribed from a paper logbook. Both records can be useful, but they provide different kinds of corroboration.
Why “third-party” matters
A purchase receipt is printed by the merchant at the moment of the transaction. It may capture the vendor, address, date, time, and amount — independently of anything the taxpayer later writes. The document exists outside your own records and can help support the account when the records are reviewed together.
A handwritten paper log is the opposite. Even when maintained contemporaneously (which is what tax authorities require), the log is a self-created document. Examiners are more likely to scrutinise it because it has no independent corroborating source. Did you really visit that client on Tuesday afternoon, or did you reconstruct it three weeks later from a calendar entry? The log itself can’t answer that question.
The exact treatment of any record depends on jurisdiction, deduction method, and the rest of the file. A receipt can add useful independent corroboration, but it does not replace a sensible contemporaneous mileage record or determine whether a trip is deductible.
How RoadStance scores it
RoadStance describes the evidence associated with each trip in your log:
| How the trip was created | Evidence quality |
|---|---|
| GPS plus linked receipt | GPS + Receipt |
| Auto-captured GPS without a receipt | GPS-only |
| Add to Trips from a receipt row | Receipt-backed |
| Transcribed paper log | Paper log; retain the original |
| Memory reconstruction only | Memory only; weakest support |
“Receipt-backed” and “Paper log” describe different sources of support. A receipt-backed trip may be reconstructed after the fact, but the receipt provides an independent source for details such as the vendor and transaction time. The resulting trip record still needs a sensible purpose, distance, and review.
When a receipt is linked to a GPS-tracked trip, the two records can corroborate one another: the GPS supplies the route, while the receipt supplies independent transaction details. Neither record by itself guarantees that a trip satisfies a particular authority’s requirements.
What about the “Add to Trips” path?
If GPS missed a trip — phone in airplane mode, walking from the parking lot before the app armed, dead battery — a receipt can help you recover the trip. RoadStance’s Add to Trips action lets you create a trip from a vendor receipt for review. Distance is computed from the routing engine (“Map Calculated”, not “User Estimated”), the address is geocoded from the printed vendor location, and the trip is marked Receipt-backed.
For multi-stop outings — Home → Vendor A → Vendor B → Home — you can chain receipts in order, run Calculate Distances, and reconstruct the sequence for review. The resulting trip record should still be checked for a sensible purpose, distance, and supporting documentation.
What this means for your records
Three practical takeaways:
- Link the receipt. If GPS tracked the trip, linking a receipt adds independent transaction details to the route record.
- Keep recording every drive. Many business trips do not generate a receipt at all, such as visiting a client or attending a meeting. A GPS-only record can still be useful supporting material.
- If you missed a trip, use available evidence. A receipt can help reconstruct the trip more reliably than memory alone. Review the completed record and retain the original receipt and other supporting records according to your advisor’s guidance.
RoadStance provides record-keeping tools and general information. It does not determine deductibility, guarantee compliance, or replace advice from a qualified accountant or tax professional. Whether any specific record is accepted depends on jurisdiction, deduction method, and the rest of your records.
