I'm not sure about KLM specifically, but in general it works the following way
One would think that the airline would encourage cancellation to no-shows, so they can resell the seat. But due to their convoluted revenue optimizations systems, that's not the case.

Every flight has rules attached to it which sets out the conditions for the particular flight. You should have received it via email when you booked. You can otherwise request it from the airline.
For example, this is a Qatar flight to Johannesburg from Dublin (https://matrix.itasoftware.com/#view-rules:research=DUBJNB;solution=0fNXz2onl1MHLsrfQzptto8/Bsts6jTuULSSKwKdQlggJE00A;fare-key=0/0), it has the following penalties listed:
Category 16: Penalties
CANCELLATIONS
ANY TIME
CHARGE USD 85.00.
CHARGE USD 170.00 FOR NO-SHOW.
CHANGES
ANY TIME
CHANGES PERMITTED.
CHARGE USD 85.00 FOR NO-SHOW.
On the other hand, I had a ticket with Norwegian Airlines over the summer I didn't use and there wasn't a cancellation fee nor a no-show fee. It depends on the airline and the class of ticket sold.

Either way you should try to recoup the taxes and fees. I think at least in Europe they're required to repay them for flights you don't use, since they're only paying them on your behalf if you actually take the flight.
