Trying to book a hotel using booking.com it states that "Additional charges may apply"

What are those charges?
How to calculate them?
Do I have to Pay them in cash?

It really depends and even Booking.com does not know which is why they use the word may. Generally speaking there are additional fees that they either cannot collect or cannot calculate due to complex rules that need more information than provided.

Sometimes there are no additional fees at all but often there is something charged by the locality. From the one example you show, Booking.com already calculated with local city tax which is included and known at the time. The last time I booked with them, the additional fee was 0.5 Eur per night which was a Tourist Tax with it being applicable to me as a tourist but probably not be applicable to someone local or on a different visa. Some hotels will collect them at check-in but most at checkout when you settle the bill which makes it easy to pay by card. I did not encounter a time when it was required to pay cash but that does not mean it is impossible.

To calculate them you can do some research about your destination but the more certain way to know is to just call the hotel in question.

    @blankip, it may depend on location but I have never had to pay more than the advertised price (plus tourist tax) nor have I heard from friends that they were charged more.

    Re tourist tax: I once would have had to pay a trivial amount of such a tourist tax in Germany. Only I was there on business, so it didn't apply to me - I just had to fill out a simple form stating the purpose of my trip. And of course booking.com or other channels can't know such details (or whether I'll even bother to spend half a minute filling out that form to save a few Euros). Commented Sep 16, 2020 at 6:27

    @blankip Which country are your experiences from? I've used booking.com extensively throughout Europe and never once been charged more than stated on the booking

    I've certainly paid a tourist levy (in France) on top of booking.com a couple of times. Often it's a requirement by the city for hotels to collect this directly. Sometimes if you go to the hotel's webpage (even after booking through booking.com) there will be a warning about this on their webpage. Commented Sep 17, 2020 at 9:18

    @HannoverFist Wow, that's outrageous. I don't recall anything of the like last time I was in Vegas (but that was like 6 years ago). Also, Raider tax - as in Oakland Raiders? Why the hell would you pay for them in Las Vegas????

As booking.com states, requirements made directly to the hotel, like extra beds, cots for babies or pets allowed at extra pay, will be charged by the hotel.

Those are charges you should know about as you requested them or agreed to them.

Tourist tax is also to be paid directly to the hotel but is often already mentioned on the booking page.

An extra charge not yet know may be cleaning cost after illegal smoking or having pets in the room when not allowed.

How you pay these charges depends on the hotel, often they give you the options cash or cards but some only take one kind of payment, booking.com mostly mentions that in the hotel information on the booking page.

Cleaning charges can be taken through the credit card with which you secured the booking.
