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?
| To match | You would need | Difference |
|---|---|---|
| Luxembourg at 120,000, working in Belgium | €149,840 | +24.9% |
| Belgium at 120,000, working in Luxembourg | €95,943 | -20.0% |
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.
