Yes, and if something is not allowed in the constitution, then the federal government does not have the power to do it. The states could do it, but I find the likelihood of all 50 states adopting a wealth tax to be extremely unlikely.
If it's popular enough to get through the House and Senate, it would have to be drawing widespread public support across the political spectrum.
At that point, there would be a lot of pressure on state legislatures to ratify an amendment. Anyone who voted against it would be putting a target on their back in the next election.
