Different Tax Proposals and Their Reach The deadline for resolving the pending fiscal crisis is less than a week away and, absent a breakthrough, spending cuts and tax increases on every income level will go into effect on Jan. 2. During their negotiations, President Obama and Speaker John A. Boehner have sought to keep tax rates at their current level for some taxpayers while letting them rise for high earners, but they have not agreed on where to set the income threshold. Mr. Obama has called for rates to go up on income above $250,000 (he later increased his offer to $400,000), Congressional Democrats have said they would agree to $500,000, and Mr. Boehner has called for a $1 million threshold. Here is a breakdown of what portion of earners, income and taxes would be affected at three different levels.
