Article 27

1. Interest shall be calculated from the day following the last day for payment of the refund pursuant to Article 22(1) until the day the refund is actually paid.

2. Interest rates shall be equal to the interest rate applicable with respect to refunds of VAT to taxable persons established in the Member State of refund under the national law of that Member State.

If no interest is payable under national law in respect of refunds to established taxable persons, the interest payable shall be equal to the interest or equivalent charge which is applied by the Member State of refund in respect of late payments of VAT by taxable persons.
