Previously mentioned the expanded 1099 reporting that would have gone into effect in 2012. This would have required all businesses and ministries to report on 1099s the payments to any vendor over $600. The major change in the rules is the exception for incorporated businesses would have gone away.
On 3-14-11 the President signed legislation that repeals the expanded reporting requirement.

The bill passed the House on March 3, approved in the Senate on April 5, and was signed April 14.
