This is great, but republicans are gonna hate it. They want everyone to hate taxes with a passion, so they make it difficult, time consuming and expensive to pay your taxes, and make government services as bad as possible so even poorer people who don’t pay much tax feel they get a bad deal out of taxation.
If ordinary people found it easy and convenient to pay taxes they might notice that they get more out of government than they put in and that rich people are bearing more of the cost than they are. If they thought that, they might support tax increases or things that horrify republicans like medicaid for all.
