With effective from November 1, 2007, the airport tax at Denpasar’s International Airport Ngurah Rai is Rp.150,000 for international flights. All travelers heading to a destination outside Indonesia have to pay this tax after check-in.
The payment of airport tax must make in cash and only Rupiah can be accepted; so make sure you reserve some Rupiah for this purpose.
Just for your information, if Indonesian citizens wish to travel oversea, they need to pay an additional Rp.1,000,000 fiscal before leaving Indonesia.
However, if an Indonesian citizen who is currently working in other countries but returns to Indonesia during the employment period, they can be exempted for the fiscal charge provided the address in his passport has updated to his current employer’s company address.
Nobody on the airport knows if this is a "TAX" or "SERVICE FEE" :)
But the real problem ist the exchange rate for foreign currencies.
Of course you can pay in foreign currencies, but for example the exchange rate13 eur for 150 000 Rp. is the worst in all Indonesia - this is a reall ripp-off !!!
Pay must in Rupiah
Airport tax must be paid in Rupiah cash. It is recommended that visitors prepare the required amount of money in advance, and save it for later. If you are arriving in Indonesia and then transiting/connecting to a domestic flight, you will need to get some Rupiah from an ATM or money changer before checking in for the second flight.
