If you are 65 years old and a resident of Ecuador you can get the IVA tax you paid during the year refunded by the SRI. In Salinas, you will need to go to the SRI office located in the Centro de Atencion building located on the main road going towards El Paseo Shopping Center and speak to a representative.
I was told that you will be issued an SRI number. You are required to keep your facturas – these are the receipts showing your cedula number, name etc. I understand that you are required to complete a form and submit it to the SRI for your refund. This can be done several times during the year, it is not necessary to hold your receipts and submit them at the end of the year. At 12% this adds up to a nice savings.
