New spanish taxes

According to https://www.avalara.com/vatlive/en/country-guides/europe/spain/spanish-v..., I think we're already covered. Commerce defines the rates described there: 21%, 10% and 4%.

So marking this as "won't fix".

Sorry for the long response delay. @jacsick The page you are referring to is outdated. You should read the current taxes in the official government website: https://sede.agenciatributaria.gob.es/Sede/en_gb/iva/calculo-iva-repercu...
Since the beginning of October (2024), there is a new tax for bread and other kind of food (2%).

I have changed two files for the new conditions and mantain the others:

$zones['es'] = new TaxZone([
      'id' => 'es',
      'label' => $this->t('Spain'),
      'display_label' => $labels['vat'],
      'territories' => [
        // Spain without Canary Islands, Ceuta and Melilla.
        ['country_code' => 'ES', 'excluded_postal_codes' => '/(35|38|51|52)[0-9]{3}/'],
      ],
      'rates' => [
        [
          'id' => 'standard',
          'label' => $labels['standard'],
          'percentages' => [
            ['number' => '0.21', 'start_date' => '2012-09-01'],
          ],
          'default' => TRUE,
        ],
        [
          'id' => 'reduced',
          'label' => $labels['reduced'],
          'percentages' => [
            ['number' => '0.1', 'start_date' => '2012-09-01'],
          ],
        ],
        [
          'id' => 'super_reduced',
          'label' => $labels['super_reduced'],
          'percentages' => [
            ['number' => '0.04', 'start_date' => '1995-01-01'],
          ],
        ],
        [
          'id' => 'second_reduced',
          'label' => $labels['second_reduced'],
          'percentages' => [
            ['number' => '0.02', 'start_date' => '2024-10-01'],
          ],
        ],
        [
          'id' => 'aceites_pasta',
          'label' => $labels['aceites_pasta'],
          'percentages' => [ 
            ['number' => '0.1', 'start_date' => '2023-01-01'],
          ],
        ],
        [
          'id' => 'exento_alm',
          'label' => $labels['exento_alm'],
          'percentages' => [ 
            ['number' => '0.00', 'start_date' => '2023-01-01'],
          ],
        ],
      ],
    ]);

It works good on the website, but the problem with JSON:API isn't solved.

I have reopened the issue because It isn't solved.

You already have a reduced rate... Why not using tax? What would be missing would be the 0% tax, but if we add it it'd have "zero" as its id... We don't typically localize the rate IDS.

Hi. Thanks for your help.
We have products in all kind of rates. We can't use "reduced rate" because it is different to "aceites_pasta". At this moment It has the same percentage, but It may change sooner. The tax rate is assigned individually to each product and I have to assign the right tax to every one base on the kind of tax and not by the percentage. It works good with this rates.
But actually, my problem is with json:api. When I add the new rates to those files, I don't know why It throws an error. If I remove my new rates, I works good. Investigating the problem, I have found that in the validate function in TaxNumberConstraintValidator class, $tax_number_type returns "other" type instead of "european_union_vat". And then, $tax_number_type instanceof SupportsVerificationInterface returns false.
