I think TracyS1 is correct. Based on the OBBB provision, those who are married filing jointly and have MAGI over S150,000 have their total 12,000 senior bonus reduced at an accelerated rate since the 6% reduction is stacked on each taxpayer. So, If the joint income is 180,000, there is an overage of 30,000 (180,000 minus 150,000 equals 30,000).
That overage is multiplied by 6% (30,000 x .06 = 1,800). That 1,800 is then subtracted from each taxpayer's 6,000 bonus, leaving each with only 4,200. The total reduced deduction is then only 8,400 instead of 12,000.
The accelerated reduction continues until, at 250,000, the bonus disappears.
