Attention to all admins using scripts for reducing VAT for Spanish regions:
Shopify is starting to implement zero VAT for these regions. As of 12 NOV 2021, out of four, two are VAT compliant.
This means that unsupervised scripts giving 21% back for ZIP codes starting with 35, 38, 51, 52 need to be fixed until all regions are done.
As there isn’t a clear timeframe when all the regions will be compliant, having both Shopify’s fix and a script will generate double price reductions.
Regions implemented: Melilla and Ceuta.
Pending: Santa Cruz de Tenerife and Las Palmas.
