Replying to this because I can't edit the comment anymore. I overestimated the tax by a lot, I misread the chart and was adding the "Cuota" (sum of previous row taxes) from 1 row below what I should have. They only pay 3,108.51 on the first 668,499.75. This puts the total tax at about half of my estimate, so only a ~0.35% drag on their 2M portfolio. It's a very progressive tax, basically goes up 10X for really rich folks (>10M they take 3.5% of total wealth).
