You can get a VAT refund if you are a permanent resident of a non-EU country and if you have spent more than €175.01 on your purchases. Please read the official tax refund guidelines.
Please note VAT refund is available not only at the airports, but also at some large stores in Paris. Please learn more at Global Blue website.
If you are planning to take care of tax refund right before you leave, please allow enough time at the airport to complete all steps required to receive your tax refund.
