How to calculate toll taxes in HERE Routing API

Question:

How can I get the toll cost with no taxes, or with the taxes details that I can subtract?

(background: using the toll cost calculation in the routing API, it is returning full cost with all taxes. For some of our clients, only the net amount, without taxes, is of importance)

Answer:

The HERE Routing API does not provide tax‑exclusive toll prices, nor does it expose the tax components so you can subtract them.

HERE returns final toll prices exactly as charged by the toll operator, which already include whatever taxes or fees that operator applies.
HERE does not provide any breakdown of:

Base toll price (net)
Tax amount
VAT percentage
Additional surcharges

This is confirmed by the fact that HERE returns toll data as flat “prices in local currencies” with no tax fields, as described in the official HERE Toll Cost documentation. https://www.here.com/learn/blog/toll-cost-routing

Additionally, HERE provides options for rollups (per road link, per country, per toll system) and breakdowns of toll categories (road sections, area admissions, ferry costs), but none of these include tax details.
