Property valuation and accounting

1What impact do Aestim reports have on capital gains calculations?
 The new provisions (2026 Tax Reform Act) on capital gains tax require absolute precision. Our experts provide Brussels-based firms with objective and certified valuation reports. This gives you a solid, quantified basis for ensuring the accuracy of your clients’ tax returns.
2In what ways are your experts essential for a share deal?
When selling a property company in Brussels, the valuation of the property is at the heart of the negotiations. Aestim commissions independent experts to carry out a thorough audit of the asset. Their factual findings provide the basis for justifying the value of the shares during the due diligence process.
3Are the reports enforceable against the Federal Public Service (FPS) Finance?
Absolutely. Aestim works with professionals who are authorised by the Federal Public Service Finance and certified by RICS or TEGoVA. In the event of a tax audit relating to capital gains or a restructuring, our legally binding reports protect your accountancy firm’s liability vis-à-vis the tax authorities.
4Are Brussels’ town planning restrictions taken into account?
The Brussels property market is complex, and compliance with town planning regulations (CoBAT) has a significant impact on an asset’s market value. Our experts have a thorough understanding of these local requirements. They take these factors into account in their valuations to ensure a realistic valuation with no unpleasant surprises.
5How long will it take for my practice to receive the assessment report?
Corporate transactions such as share deals require a high degree of speed. As soon as our Brussels-based expert has completed the site visit, they will draw up and provide you with a comprehensive, impartial and well-documented report within three working days. This helps to speed up your due diligence process and the signing of contracts.
