Frequently Asked Questions

A Belgian tax consultant advises on corporate tax planning, VAT structuring, transfer pricing, cross-border tax optimisation, withholding tax relief, tax incentives (innovation deduction, investment deduction), tax return preparation, and representation before Belgian tax authorities. They also assist with tax audits and disputes.
Hourly rates for Belgian tax consultants typically range from €150–€350/hour depending on seniority and firm size. Annual tax advisory retainers for SMEs range from €2,000–€8,000. Specific projects (transfer pricing documentation, tax ruling applications, restructuring) are quoted separately.
A bookkeeper handles daily transaction recording and basic VAT/tax filings. A tax consultant provides strategic tax planning, advises on complex structures, handles tax incentive applications, manages tax authority correspondence, and optimises your overall tax position. For international businesses, both roles are typically needed.
ITAA (Institute for Tax Advisors and Accountants) is the Belgian professional body regulating tax advisors, accountants, and bookkeepers. Only ITAA-registered professionals can use the title 'belastingconsulent/conseil fiscal' and represent clients before Belgian tax authorities.
Yes. ITAA-registered tax consultants can represent you before the SPF Finances during tax audits, rulings, objections, and appeals. They can sign and file tax returns on your behalf, respond to information requests, and negotiate settlements with the tax administration.
Key incentives include: SME reduced rate (20% on first €100K), innovation income deduction (up to 85%), notional interest deduction, investment deduction (8-13.5%), R&D tax credit, expatriate tax regime, withholding tax exemption on researchers' salaries, and various double tax treaty benefits across 95+ treaties.
A tax ruling (voorafgaande beslissing/décision anticipée) is a binding advance agreement from the Belgian Ruling Commission (DVB/SDA) on the tax treatment of a specific transaction or structure. Companies use rulings to obtain certainty on transfer pricing, restructurings, or the application of tax incentives before implementing them.
Strongly recommended. Foreign companies operating in Belgium face permanent establishment risks, withholding tax obligations, VAT registration requirements, and transfer pricing rules. A Belgian tax consultant ensures compliance and identifies opportunities to reduce tax exposure through treaties and incentives.
