Work incapacity in Belgium 2026: what you actually receive
Nobody reads this page before they need it, and that is precisely the problem. An employee who falls ill goes from 100% of their salary to 60% of a capped amount in a month. A self-employed person drops straight onto a flat rate with no connection to their income. Here are the exact amounts for 2026, and the deadlines that cost you rights when you miss them.

Benefits insurance is the other side of your health insurance fund: alongside reimbursing care, it pays a replacement income when you can no longer work. The system distinguishes two periods — primary incapacity, the first year, and invalidity beyond that — and treats employees and the self-employed very differently.
Employee: the first month is on the employer
Before the health fund steps in, the employer owes a guaranteed salary. Its duration and amount depend on status — the rules for blue-collar workers, historically less generous, are set out below.
| Period (blue-collar worker) |
Pay owed by the employer |
| Days 1 to 7 | 100% of gross pay |
| Days 8 to 14 | 85.88% of gross pay |
| Days 15 to 30 | 25.88% of capped gross pay plus 85.88% of the portion above the cap |
For a white-collar employee, the guaranteed salary is in principle paid at 100% for the first month. In both cases blue-collar workers must have one month's uninterrupted service, and a waiting day may apply depending on circumstances.
⚠️ On day 31 the drop is brutal. The guaranteed salary stops and the health fund takes over at 60% of a capped amount. On a high salary, that transition can wipe out more than half your net income overnight. That is when a guaranteed-income insurance — often bundled into fringe benefits — makes all the difference.
Employee: the health fund amounts in 2026
From the second month, the benefit is 60% of lost gross pay, capped, and calculated on a six-day week (Monday to Saturday) — hence amounts expressed per day rather than per month.
| Daily benefit (primary incapacity) |
1/1 → 28/2/2026 |
From 1/3/2026 |
| Maximum | €108.68 | €112.08 |
| Minimum from month 3 | €63.01 | €64.27 |
| Minimum, regular worker with dependants (from month 4) | €79.51 | €81.10 |
A floor therefore only kicks in from the third month of incapacity, and it can never exceed your gross daily salary. From the seventh month, minimums differentiate by family situation — with dependants, single, cohabiting — and by whether the worker is classed as regular.
💡 Converting to a monthly amount
The six-day system means a month counts roughly 26 payable days. A benefit at the maximum of €112.08 a day therefore comes to around €2,900 gross a month. To compare with your current position, our net salary calculator and our page on understanding your payslip give the starting point.
Self-employed: a flat rate, from day one
The self-employed regime is simpler and, depending on your income, far harsher: the benefit is a daily flat rate with no link to turnover or profit.
| Family situation |
1/1 → 28/2/2026 |
From 1/3/2026 |
| With dependants | €79.51 | €81.10 |
| Single | €63.01 | €64.27 |
| Cohabiting | €48.32 | €49.29 |
What that really means
A cohabiting self-employed person receives about €1,280 gross a month, whatever income they were generating before.
Two direct consequences:
🛡️
Guaranteed-income insurance is not a luxury
It is the only way to bridge the gap between the flat rate and your actual standard of living. The premium is deductible and the subject belongs in every self-employed person's plan, alongside the PLCI.
💳
An exemption from contributions is possible
From the second quarter following the start of incapacity, a self-employed person recognised as incapacitated can obtain an assimilation for illness: exemption from social contributions while retaining rights, including pension rights. The application goes through the social insurance fund — see self-employed social contributions.
The flat rate also varies depending on whether the business is continued or ceased during invalidity: the INAMI scales distinguish the two, with higher amounts on cessation.
Beyond one year: invalidity
After twelve months of recognised incapacity you enter invalidity. The decision rests with INAMI's Medical Invalidity Council, on the proposal of your health fund's medical adviser.
1
The percentage now depends on your family situation
Highest with dependants, intermediate for a single person, lowest for a cohabitant. Guaranteed minimum amounts apply in each category.
2
Withholding tax has been deducted since 2026
New from 1 January 2026: the health fund deducts withholding tax on benefits paid during invalidity. The gross does not change, the net falls — but your tax balance at return time falls by the same amount.
3
The reintegration pathway
A structured process allows an adapted return: adjusting the workstation, a different role, or partial resumption. It is separate from the procedure for termination on medical force majeure.
4
Authorised partial resumption
With the medical adviser's prior agreement, you can resume part-time work while keeping part of the benefit. The agreement must be obtained before you resume: starting and then asking exposes you to losing benefits and having to repay them.
The three changes of 1 January 2026
1 January 2026
Withholding tax on invalidity benefits
Deducted at source by the health fund. The measure, originally planned earlier, was postponed to this date.
1 January 2026
Certificate limited to 3 months, renewable
An incapacity certificate can no longer cover more than three months at a time. You must have it renewed, or payment stops.
1 January 2026
Mandatory electronic transmission by the GP
For incapacities over fourteen days and their extensions, the doctor sends the certificate directly to the health fund. That does not exempt you from checking the declaration actually arrived.
The steps and deadlines not to miss
📞
Notify the employer immediately
From day one, following the procedure in the work rules. A delay can cost you the guaranteed salary for the days concerned.
📄
Declare to the health fund within the deadline
The declaration deadline is short and lateness carries a financial penalty: reduced benefits for the period of delay. It is the most common cause of lost rights, and the most avoidable.
🩺
Attend the medical adviser's appointments
An unjustified absence can suspend benefits. A change of address must be reported, or you will never receive the summons.
✈️
Seek permission before any stay abroad
Travelling abroad during incapacity requires the medical adviser's prior agreement. Without it, benefits for that period can be reclaimed.
💼
Never resume any activity without prior agreement
Even a few hours, even unpaid for your own business. That is the heaviest ground for recovery, because it covers the whole period concerned.
Planning ahead: what you arrange while all is well
👔 Employee
Your safety net may already exist
•
Check whether your employer has taken out
guaranteed-income insurance: many group schemes include one, and few employees know it.
•
Look at what your joint committee provides: some impose a top-up benefit.
•
Your mortgage protection insurance generally covers death only: incapacity is a separate, often optional cover.
💼 Self-employed
Nobody will do it for you
•
Guaranteed-income insurance with a suitable waiting period is the first protection to put in place.
•
A cash reserve covering three to six months of fixed personal and business costs.
•
Knowing the assimilation-for-illness procedure at your fund in advance: invoking it early avoids unpaid contributions piling up.
