The IRS announced it has delayed the filing requirement for
companies to report the cost of supplying healthcare coverage to their
employees. Employers were originally required next year to include on workers' W2
forms what it cost to supply them healthcare coverage. That requirement
is now optional in 2011, to give employers more time to adjust their
payroll systems.
