The gross you would need to match

Comparing net pay at the same gross answers one question. The more useful one is usually the reverse: what would you have to be paid on the other side to be no worse off?

Belgium at 100,000, working in Luxembourg €79,813 -20.2%

Solved by running each engine backwards until the take-home figures agree, so the answer accounts for the whole deduction structure rather than applying an average rate.

What a raise costs at this level

In Luxembourg, 49.9% of the next 1,000 euro of gross pay disappears into deductions, against 59.6% of the next 1,000 euro in Belgium. Both sit above the effective rates in the table, which is the normal shape of a progressive system: the average is held down by allowances and lower bands that the last slice of your pay has already passed.
