- Is it necessary to pay excise duty and in what amount?
- Is reporting in the SENT system mandatory?
- Does the entered CN code imply an obligation to pay fuel duty or emission fee?
- Does the purchase of goods with a specific CN code involve keeping the mandatory fuel stocks?
- Is it necessary to have an energy license?

High fines for violation of obligations
Our experience shows that an unexpectedly large number of entities are not aware of the fact that their business has obligations specified in: the Excise Duty Act, the Energy Law, the Act on monitoring of transport of sensitive goods (SENT), Act on fuel stocks, act regulating the fuel surcharge.
Even if at first glance it seems that these regulations do not apply to many entities due to the type of business conducted, the reality may be completely different.
Few people are aware that purchasing even small quantities of lubricating oils from abroad involves, for example:
- Registration for excise duty purposes.
- Submitting excise duty declarations.
- Payment of excise duty.
- Entering in the register of importing entities.
- Submitting monthly reports thereon.
Violation of the above obligations may result not only in high fines, but also in personal criminal and fiscal responsibility. Our Tool helps to mitigate this risk.
