Loans with reduced interest payment are classified as 'advantages of all kinds' (voordelen van alle aard/avantages de toute nature). On these advantages tax is to be paid. The taxable amount is mainly calculated on the basis of the difference between:

• the reference interest rate per loan type determined by the government
• the interest rate to be paid to the employer.

Depending on the regularity of the loan repayments, the taxable advantage is added to the total of taxable amount or liable to an exceptional tax rate (e.g. Capital paid back at the end of the loan duration).
