> Being self-employed does have a monthly quota but it only kicks in after I think 2 years (first 6 months gratis, second 6 months small fee, third 6 months bigger fee and so on), so you can get up and running relatively cheap. Nope, there are some exemptions, but if you want to run a business (even self-employed) in Spain, you need to pay 300€/month, even if you have zero revenue.
