Indirect taxes include stamp duties, a fixed fee on increase in capital of EUR 50, a transfer or registration tax on the transfer and leasing of real estate (at rates varying between 0.2% and 12.5%). At the regional level in Belgium, an annual tax is levied on the notional rental income of immovable property, including land, buildings, and industrial equipment. The rate varies by region: 3.97% in the Flemish region and 1.25% in the Brussels and Walloon regions. Provinces and communes may impose additional surcharges. While the tax and surcharge are deductible for corporate income tax, they are not deductible for individual income tax unless the building is used for business purposes.A 100% special assessment is applied to "secret commissions," which refer to expenses where the beneficiary isn't properly identified through correct forms filed with Belgian tax authorities. These expenses encompass various forms of professional income, including commissions, bonuses, and benefits in kind, paid to beneficiaries, as well as remuneration to company personnel or former members and lump-sum allowances for staff expenses. The reporting scope extends to variable allowances, albeit only resulting in administrative fines for omissions rather than the secret commissions tax. Additionally, income from copyrights and related rights falls under this assessment. Under specific conditions, the secret commissions tax may be reduced to 50%, and in certain instances, it may not apply at all.
Banks are subject to a bank levy and a subscription tax on savings deposits.
Social security contributions - generally fixed at 30.57% of 1.08 times the gross salary for blue-collar employees and 25% of the gross salary for white-collar employees - in practice vary according to the size and industry of the company and the salary of the employee. For blue-collar employees, an additional annual contribution of 10.27% is due on 1.08 times the gross salary.
Certain components of the salary package are subject to specific social security contributions. These include a carbon dioxide solidarity contribution for personal use of a company car, an 8.86% contribution on the employer's contribution for group insurance, and a 3% contribution known as the "Wijninckx contribution" on supplementary pension premiums exceeding certain thresholds.
An annual tax is levied on securities accounts held by both resident and nonresident individuals, companies, and legal entities, including those subject to the "Cayman tax." This tax aims to prevent Belgian residents from exploiting tax advantages by holding assets in low-taxed entities, implementing "look-through taxation" and taxing distributions. For residents, the tax encompasses both Belgian and foreign securities accounts, while for nonresidents, it applies primarily to Belgian securities accounts. However, certain tax treaties may exempt nonresident-held securities accounts from taxation. The tax rate is 0.15% on the average value of taxable financial instruments within the securities account, excluding nominative securities, exceeding EUR 1 million during the reference period, which spans from October 1 to September 30. Certain financial undertakings are exempt from this tax.
