The value of your company as at 31.12.2025, independently fixed.
A valuation report drawn up by an independent professional. Ready in four weeks.
Possible until 31.12.2027. After that, the option is gone.
Since 1 January 2026, Belgium taxes realised capital gains on financial assets at 10%, with an annual exemption of 10,000 EUR per taxpayer. Only the increase in value from 1 January 2026 onwards is taxable. For unlisted shares, the value as at 31 December 2025 is therefore the dividing line between the taxed and untaxed part of a later sale.
Three dates
31.12.2025
The snapshot
The value on this date is the starting point. Everything built up before it stays out of scope.
01.01.2026
The tax applies
10% on the gain realised after this date, with an exemption of 10,000 EUR per year per taxpayer.
31.12.2027
End of the window
Until then, an independent valuation report can be drawn up. After that, the option is permanently gone.
The difference in one view
1,250,000 EUR
Substantiated valuation, DCF cross-checked against multiples. Signed by an independent professional.
870,000 EUR
The formula the tax authority falls back on without a report. The 380,000 EUR difference is taxed later.
Figures shown for illustration. Every value here sits next to the date it refers to.
What happens if you do nothing
Without a report, the tax authority falls back on a fixed formula: equity plus four times ebitda. For many healthy companies, and for almost every holding or real-estate company, that formula sits below the real value. The difference is taxed later.
A report changes nothing about your company. It fixes what it was worth on 31 December 2025, in a form that is still readable and reconstructable years later.
Your own accountant cannot draw up this report. The law requires a statutory auditor or certified accountant who is not the company's usual practitioner.
Three things are fixed
- Independent
- Drawn up by a professional who is not your own accountant, exactly as the law requires.
- Defensible
- One method, documented, reconstructable years later. You do not use this report in 2026, you use it in 2031.
- On time
- Fixed steps, a price confirmed in writing up front, and a date on which you have the report.
The four questions
Does this apply to me?
It applies if you hold shares in an unlisted Belgian company that could later be sold or transferred. The value as at 31.12.2025 then determines which part of the gain is taxable.
What does doing nothing cost me?
Without a report, the statutory formula applies: equity plus four times ebitda. If that formula is below the real value as at 31.12.2025, the difference is taxed at 10% on a later sale.
What does it cost and how long does it take?
The price depends on the company and is fixed in writing before work starts. The lead time is four weeks to the draft report, counted from the moment the general ledgers and the business plan or budget are available.
Will it hold up if the tax authority pushes back?
The report states the method, the inputs, the sources and the judgements, and is signed by an independent, ITAA-certified professional. That keeps it reconstructable years later.
