14.6. Interest Compensation for Overpayment of Tax

The taxpayer is entitled to an interest compensation for overpaid tax.

Effective from tax year 2018, the interest penalty for late payment of tax is based on the average of the reference indices with respect to 10-year OLO's (euro-denominated securities) published by the Belgian Debt Agency for the months of July, August and September of the preceding year, which may range between 4% - 10%. The interest rate on overpaid tax/ refund is 2 percentage points lower than the interest rate for late payment.

The rate of interest compensation for overpaid tax is 2% (previously, 7% up to 2017).
