Common mistakes in mileage logs. What Skatteverket looks for
Ten errors often found in mileage logs during Skatteverket audits. What to watch out for and how to avoid trouble.
Most mileage logs that fail during a Skatteverket audit have the same kind of shortcomings. They are not serious manipulations but incomplete documentation that starts as carelessness and ends in default benefit taxation. Here are the ten most common mistakes and how to avoid them.
1. Odometer missing or inconsistent
The single most common error. Odometer is forgotten one day a week and reconstructed afterward. When Skatteverket sums it up, gaps appear that are hard to explain. Solution: read the odometer automatically from the car.
2. Identical purpose on multiple lines
“Meeting” or “client” line after line is a red flag. Skatteverket reads it as the line being filled in after the fact without connection to actual errands. Solution: write clearly who the meeting was with, ideally company name and purpose.
3. Individual days missing
If you normally commute to the office but a Thursday in March is missing entirely it looks odd. Were you sick? On holiday? Skatteverket does not ask, but notes that the log is not comprehensive. Solution: even sick days and vacation days should be marked as “no driving”.
4. Driver missing on multi-driver cars
Cars driven by multiple people should have the driver indicated per trip. If missing the assessment becomes default. Solution: set main driver and confirm or adjust on individual trips.
5. Business trips without clear start or end address
“Stockholm to Gothenburg” is not enough. Addresses or at least clear locations for start and stop are required. Solution: use actual addresses or geofence zones with clear names.
6. Private trips classified as business
This is the expensive one. Trips to and from the regular workplace are commute, not business. Misclassification here makes Skatteverket question the rest of the log. More on the borderline in Private trip vs business trip.
7. Corrections without justification
A modified odometer or a changed line without explanation suggests manipulation. Solution: an audit trail showing when and why the change was made.
8. Detours not counted correctly
A business trip that passes the preschool or a grocery store often needs to be split. Long detours classified as business all the way is a classic error. Solution: rules that handle passage zones.
9. Car change mid-year without log following
When the car is replaced with a new one the odometer should be broken and a new one started. Without the transition, total driving becomes impossible to verify. Solution: change vehicle in the app and let the system handle odometer handover.
10. Log not kept for six years
Skatteverket can require a log up to six years back. A lost file or deleted app can make old years impossible to show. Solution: a service that stores history centrally and exportably.
“Is any of this disqualifying?”
Individual errors are rarely disqualifying, but a pattern of several errors can make the entire log questioned. It is the credibility of the whole that counts.
What an automatic log solves
Of the ten errors, eight are directly eliminated by an automatic mileage log like DriveLog: odometer automatically, purpose and driver with audit trail, corrections with justification, geofence for addresses, rules for commute and detours, six-year storage.
What remains? Just filling in purpose where needed and checking individual trips once a week.
