What the new ATF VAT rates mean
The revised rates apply to aviation fuel sold by oil companies to scheduled airlines for domestic flights. Under the notification, airlines will have to submit a declaration signed by the purchaser along with their monthly tax returns to establish that the fuel is intended for domestic aviation operations.
