Currently, there are multiple Joint Resolutions in the House - 112th Congress, for a balanced budget amendment. There appears to be two which have the most support, H.J.Res.1 with 109 cosponsors and H.J.Res.2 with 178 cosponsors. They are basically the same but do have a few minor differences. HJR1 includes a Section about limiting spending to 20% of GDP (Gross Domestic Product - the sum of the production for the country in a given year) unless 2/3 vote for increase. #2 does not have this section. #1 requires 3/5 vote to increase taxes where #2 requires a majority. Other sections appear to be identical.
