Prohibits the taxation of unrealized gains

SJR 53 would prohibit state taxation on increases in the value of assets (like stocks or property) that haven't been sold yet. It directly affects individuals and businesses holding assets that have gained value but haven't been sold. The bill simply states that these "paper profits" cannot be taxed until the asset is sold. This is a procedural bill focused on a specific tax rule change, with no additional mechanisms described in the provided details.
