When we had this same deal 4 years ago, we were not asked to pay anything at the airport other than the airport taxes. If there was any gringo tax, it must have already been included in the price of the ticket at the time of purchase.
Looks like this time around even the airport taxes are already included in the ticket. ITA shows it as HW:
Peru Airport Departure Tax (HW) $30.74
This HW is not reflected in the fare construction seen on my receipt; however, my ticket shows 135.00 fare +
103.64 taxes = 238.64 USD; and if you add up the taxes listed on ITA, including the HW amount, they total
103.64 
US September 11th Security Fee (AY) $2.50
US Passenger Facility Charge (XF) $4.50
US International Departure Tax (US) $16.70
Peru Int'l Arrival Tax (DY) $15.00
Peru Airport Departure Tax (HW) $30.74
US International Arrival Tax (US) $16.70
US Customs Fee (YC) $5.50
US Immigration Fee (XY) $7.00
USDA APHIS Fee (XA) $5.00
Hopefully this HW is indeed the same thing that we had to pay separately at the airport last time, and not an additional departure tax...
So amazing to have bought a ticket for $239 and seeing the identical itin now pricing at over $1500...!
