What happens if you do nothing?

The consequences of non-compliance with GoBD / § 4 EStG.

1% rule
an expensive flat rate

If the mileage log is rejected, the 1% rule applies — often far more expensive than the actual private use.

Rejected
for gaps

Retroactive changes or gaps cause the tax office to reject the entire mileage log.

Back payment
plus interest

Rejected mileage logs lead to back taxes plus interest for the entire audit period under § 4 of the German Income Tax Act (EStG).
