Belgian mobility budget cash balance 2026 : your net amount
Calculate the net amount received on the cash balance (pillar 3) of your mobility budget, after the 38.07% special contribution. Free, sourced from ONSS law/CIR 1992.
This tool only calculates the net amount received on the cash balance (pillar 3) of your mobility budget, not the total budget, nor pillars 1 and 2, which you should obtain from your employer.

A cash balance subject to a special contribution
The mobility budget is split into 3 pillars. The unused balance from pillars 1 (replacement car) and 2 (soft mobility) is paid out in cash, but subject to a 38.07% special contribution charged to the worker, a mechanism designed to equalise this cash-out with the social contributions normally due on a salary.
Reference points on the total budget, for information only
The total mobility budget cannot legally be lower than €3,233/year, nor exceed 20% of gross annual salary with a cap of €17,244/year (2026), reference points, not a calculation performed by this tool.
What this calculator does not do
It does not calculate the total mobility budget (depends on the TCO of the reference vehicle), nor the detail of eligible expenses for pillars 1 and 2, these amounts must be known or obtained from your employer.
Frequently asked questions
Why doesn't this tool calculate my total mobility budget?
The total budget depends on the total cost of ownership (TCO) of the replacement car you would have been entitled to, an amount specific to the leasing contract negotiated by your employer, with no generalisable public scale. This amount is normally communicated to you by your employer; this tool focuses on what it can calculate with certainty: the treatment of the cash balance.
Why aren't the expenses of pillars 1 and 2 recalculated?
Pillar 1 (replacement car) depends on the same TCO specific to your contract. Pillar 2 (soft mobility) covers a long list of eligible expenses (bicycle, public transport, housing near work...) too varied for a reliable calculation in this v1. You enter these amounts as you already know them.
Who pays the 38.07% contribution?
It is charged to the worker, not the employer, it is deducted from the cash balance before you receive it. The rate is officially described as equal to the sum of the personal and employer contributions normally due on a salary.
Is the net amount received then taxed?
No. Once the special contribution has been deducted, the net balance constitutes professional income exempt from tax (article 38, §1, 33° of the CIR 1992), no additional tax deduction.
